A stylish smartphone with impressive technical characteristics is the Idol X. Initially (in 2013) it was positioned as a mid-price solution. But now, 2 years after the start of sales, this device can safely be classified as a budget device. It is its capabilities and technical parameters that will be described and discussed in detail in the proposed material.

Equipment

This “smart” phone has typical equipment (as for a device from this manufacturer). There is nothing unusual about her. It includes the following accessories and components:

• The smartphone itself has a 2000 mAh battery.
• Charger.
• Entry-level wired stereo headset.
• Interface cord.
• Brief instruction manual (it also contains a warranty card at the end, on which, when purchasing a device, the seller must put his stamp and fill it out completely).

The list above clearly lacks a cover. The body of the device is almost entirely made of plastic, it is not difficult to damage it, but it will be quite problematic for the owner of this gadget to do without this accessory. Although the front panel of the smartphone is protected by impact-resistant Dragontrail glass, in order to prevent various types of damage, it is recommended to glue a special protective film to the front panel of the device. It is also not included in the package, and this accessory will have to be purchased at an additional cost. Also, owners of the single-SIM version of this phone will have to purchase an external flash drive. The phone has only 8 GB of internal memory, and this is clearly not enough for comfortable work today.

Gadget design and its features

Most of the front panel of the gadget is occupied by a touch screen. Its diagonal is impressive even by today's standards - 5 inches. The frame width on the left and right is only 2.4 mm. Not every mid-level smartphone currently can boast of such a characteristic. The length of its case is 141 mm, width - 68 mm, and the thickness is “fantastic” 6.9 mm. Its weight is very small - 130 grams. For a device with such dimensions and characteristics, these are truly phenomenal indicators. Above the screen there is a front camera window, there is an earpiece and several sensors. Under the display there are backlit controls. It consists of three standard buttons. On the bottom side of the smartphone there are harmoniously located: a hole for a speaking microphone and a USB port. On the right are buttons that control the volume. If Idol X does not turn on after briefly pressing the lock button (located on the top edge of the smartphone), then you need to press it for 5-15 seconds and wait until the device turns on. Here, on the top edge of the device, there is an audio port (3.5 mm). With its help, the audio signal is output to a wired speaker system. These can be either speakers or headphones with a microphone. On the back cover, in addition to the manufacturer’s logo, there is also an “eye” for the main camera with LED backlight and a loud speaker.

Computational basis

Alcatel One Touch Idol X is based on one of the most productive 4-core chips from MediaTek - MT6589T. It consists of four computing modules based on an architecture code-named “Cortex-A7”. The maximum frequency of each of its computing modules can reach 1.5 GHz, and no other CPU from this manufacturer can boast exactly the same values ​​or higher. At the time of the release of this gadget, this semiconductor crystal made it possible to solve any problem. But now, 2 years later, he will no longer be able to cope with the latest generation of the most demanding toys. And here the problem is not in the CPU itself, but in the fact that software has appeared designed to run on 64-bit platforms, but this processor can only perform 32-bit calculations. All other tasks on this computing platform are performed without problems (watching videos, simple games, reading books, listening to audio, and so on).

Device video card

PowerVR SGX544MP is used as a graphics accelerator in this device. At the time of the start of sales, this video accelerator allowed solving all problems without exception. But now more demanding games of the latest generation have appeared that will simply run on it. But at the same time, this graphical solution still allows you to solve most everyday problems. This includes browsing the Internet, reading books, playing videos (including movies), and even mid-level toys - all this is possible with the Alcatel One Touch Idol X with such a graphics card.

Display

The Alcatel One Touch Idol X phone has a 5-inch display. Its resolution is equal to what is impressive today - 1920 x 1080. It is based on a matrix made using IPS technology (hence the impeccable color rendition). Well, with the help of OGS technology, the picture on the screen is not distorted even at angles that are very close to 180 degrees. Even now, two years later, not every mid-range gadget, let alone entry-level devices, can boast a display with similar characteristics. In addition to everything else, the screen in this device is protected by Dragontrail glass (an analogue of which is applied to the surface (with its help, fingerprints do not remain on the front panel of the phone).

Cameras

The main camera of the Alcatel One Touch Idol X also has impressive parameters. The photos taken with its help are of really high quality. It has a 13 megapixel sensor, which is also produced by Sony, a leading manufacturer of “sensitive” elements for phones and cameras. A similar sensor is used in the Samsung Galaxy S4 and Sony Xperia Z. The developers did not forget to equip this gadget with an autofocus system and LED backlight. This camera can record video in 1080p format (with an image refresh rate of 30 frames per second). The front camera has a more modest sensor - only 2 megapixels. But this will be quite enough for selfies or making video calls using the same Skype, for example.

Memory

Now let's look at the Alcatel One Touch Idol X from the perspective of the memory subsystem. The amount of RAM in different modifications of this gadget is always the same and equals 2 GB. At the same time, system processes occupy about 700 MB. The remaining 1300 MB can be used by the smartphone owner to run application software. The capacity of the built-in storage in the 2-SIM version of this device is 16 GB. However, there is no slot for installing an external drive. But the single-SIM version of this device is equipped with only 8 GB of disk space, but in this case, instead of a slot for a second SIM card, there is a slot for installing a 32 GB flash card. If for some reason the specified capacity of the integrated drive is not enough, then you can use “cloud” information storage services, for example, Yandex disk.

Smartphone autonomy

The Alcatel One Touch Idol X is equipped with a rather modest battery, by today's standards. Its characteristics are really not impressive: 2000 mAh based on lithium-ion manufacturing technology. According to the manufacturer, the specified capacity in standby mode should be enough for 320 hours in second-generation cellular networks and 240 hours in 3G mode. In reality, with such a battery and similar technical characteristics, you can count on 2 days of battery life in maximum saving mode. If you use this device to the maximum, then the battery will have to be charged every evening. However, there is no guarantee that he will be able to finish the work until the evening. As a result, it is imperative to purchase an additional one that can be used when the main battery charge level is low. In this case, your phone will definitely not let you down. But in this case, you will have to carry an external battery with you and also monitor its charge level.

Communications

The communication set of this smartphone includes the following interfaces:

• Wi-Fi is the main way to exchange information with the World Wide Web.
• Mobile networks of GSM and 3G standards. They allow you to make calls and exchange SMS. You can also use them to connect to the Internet. In the latter case, it will even be possible to make video calls.
• The GPS sensor allows you to determine the location of the device with a high degree of accuracy. Also, A-GPS technology can sometimes be used for these purposes.
• Bluetooth is perfect for those cases when you need to use a wireless headset or exchange data with a similar mobile device.
• The wired speaker system can be connected to a smartphone using the audio port (3.5 mm).
• Micro USB allows you to charge the battery or synchronize the device with a PC.

Software

The Alcatel One Touch Idol X smartphone, as expected, runs on the most popular operating system for various mobile devices - Android. Its version is 4.2. Of course, this is far from the latest system software today, but its presence is quite enough to run most applications. The only thing that will not work on this 32-bit version of the operating system is the latest 64-bit application programs of the latest generation. The proprietary shell of this mobile gadget manufacturer is installed on top of the operating system. Its interface is quite reminiscent of a similar MIUI shell from Xiaomi. In addition to standard applications (calendar, calculator, organizer, etc.), the installed software includes clients of international social networks (for example, Facebook) and a set of mini-utilities from Google (Gmail+, Chrome, and so on) . The user will have to install everything else from the content store (“Play Market”).

Current price

Although 2 years have passed since the start of sales, the price has remained virtually unchanged for the Alcatel One Touch Idol X. Reviews highlight its rather high cost. The smartphone itself has long been discontinued and can now only be purchased from stock. Well, regional dealers bought the device at a fairly high price, below which they now cannot lower its market value. It is currently priced at $375. Its starting price was $500. On the one hand, the device has fallen in price by $125, on the other hand, now for the same money you can buy an Xperia M4 from Sony or Mi4 from Xiaomi. Any of these devices is technically an order of magnitude better than the Idol X. As a result, this smartphone no longer looks like such a good buy compared to its analogues, which can offer their owner much more for the same money.

The Alcatel smartphone brand (owned by the Chinese company TCL Communication), which was practically in oblivion (in our country, for sure), woke up this year and presented a fairly extensive line of Android smartphones. All of them are united by the ideology of thin design, bright colors and the name OneTouch. Alcatel OneTouch Idol X is the flagship model in the line. It is thin (6.9 mm), light (120 g), bright, and interesting. Interesting first of all with a FullHD display with a diagonal of 5 inches and an IPS matrix, and in addition - a 13-megapixel camera, Android 4.2 and a price of about 3200-3500 UAH at the start of sales. The smartphone definitely looks like the most desirable among its OneTouch relatives and not only among them - with such and such characteristics and for such and such money. But Alcatel turned out to be the perfect device, and we’ll look at whether this device has any chance of becoming an idol for technophiles in this review.

Specifications

With the growth of smartphone diagonals and the ongoing arms race, the need for Full-HD screens was brewing naturally. By the end of 2013, only the lazy did not release an Android smartphone with a display resolution of 1920x1080 pixels and a pixel density of more than 400 ppi. Among the pioneers were primarily first-tier smartphone manufacturers: Samsung (Galaxy S4), HTC (One), Sony (Xperia Z /), LG (Optimus G Pro), but less famous Huawei (Ascend D2) and Oppo (Find 5), and then other Chinese. And now, by the second half of 2013, we have a good selection and a very wide range of prices. If the major players for their flagship devices also chose the most advanced processors available at the time of the device’s release (Exynos 5 Octa 5410, Qualcomm Snapdragon 600, Qualcomm Snapdragon S4 Pro), then the companies managed better than God sent. Huawei in its Ascend D2 limited itself to a processor of its own production, HiSilicon K3V2. An excellent processor by the standards of 2012, but already rather weak as of today (how rapidly everything is changing in the smartphone segment). And its performance is not the same (for a large FullHD display), and its energy efficiency is poor. Alcatel (more precisely TCL Communication) also chose a more budget-friendly option for its flagship - a quad-core Mediatek MT6589T with a clock frequency of 1.5 GHz and PowerVR SGX544 graphics. In Fly smartphones (namely, in them we first encountered this processor), it showed itself to be quite powerful and energy efficient. And definitely inexpensive. Thus, in the end, Alcatel ended up with an inexpensive smartphone with a gorgeous Full-HD display in an impressively thin body (seriously, even thinner than the Galaxy S4 by a whole millimeter). It remains to check how well the Mediatek MT6589T and 2 GB of RAM correspond to the immodest resource requirements of a Full-HD screen and how much the battery resources with a frankly modest capacity of 2 Ah are enough to work in real conditions, whether it makes sense to pay more for smartphones with cool brands on the nameplate, when there are such affordable and attractive solutions and is there life on Mars.

Frame

Those who designed this smartphone clearly did a good job and deserved, if not a prize, then certainly the right to be especially noted. After all, they broke two records at once for another “smallest five-inch smartphone” - the Samsung Galaxy S4. Alcatel OneTouch Idol X is a millimeter thinner and 2.3 millimeters narrower than the top-end Samsung smartphone of 2013. This slight difference is clearly felt when the device is in your hands. Although it cannot be said that after the Alcatel flagship, the Samsung device seems like a huge shovel. They are both compact and both comfortable. I don’t know why, but in OneTouch Idol X it’s not annoying even that the device’s screen lock button is on the top edge.

In terms of design, the OneTouch Idol X did not bring anything new to the smartphone segment. With the screen off, the device looks equally like the Oppo Find 5 and the Huawei Ascend P6. This is probably all thanks to the universal black color and touch keys that blend into the body, as well as the perfect assembly and the absence of pronounced design frills on all three devices. However, the OneTouch Idol X is a well-built smartphone. It fits well in the hand and its back cover (non-removable) is made of pleasant plastic. If the device had metal or LEDs on its body, it could easily be mistaken for an HTC or Sony smartphone - those few manufacturers who still care about using beautiful and pleasant materials.

Apparently, the connectors for the SIM card and memory card were placed according to the residual principle. Both are located in unusual places behind the plugs - on the left and right ends, respectively. Under the memory card slot there is a volume rocker key. It rises slightly, but it is difficult to feel it blindly.

Alcatel OneTouch Idol X and its kit

In general, the impressions from the assembly of the device are very good, as are the ergonomics of the case. OneTouch Idol X is not inferior to top devices from first-tier manufacturers either in terms of comfort of use or integrity of assembly.

Screen

Screen under the sun

Five inches, FullHD, IPS - and all this for fairly modest money. Sounds like a fairy tale. Looks the same. OneTouch Idol X has a practically reference screen. It is bright, with rich colors, ideal sensitivity, oleophobic coating and good color rendering. In terms of tactile sensations, the screen resembles those that respond to touches with gloves. I, of course, checked this suspicion. But the screen refused to work with thick winter gloves.

But despite the fact that the screen brightness of the Idol X is higher than that of the Samsung Galaxy S4 (see table), under the sun the screen of the Samsung smartphone looks better than the Alcatel in both manual and automatic settings. And the auto-brightness adjustment of the Alcatel flagship works strangely. Or even bad. On sunny days, I had to force it to turn off and set the screen brightness to maximum, because otherwise nothing could be seen on the screen at all. The same problem was observed in the ZTE Grand S smartphone.

Device name	White field brightness, cd/m2	The brightness of the black field, cd/m2	Contrast
Alcatel Idol X	360,76	0,24	1503:1
Huawei Ascend D2	310,52	0.30	1037:1
Sony Xperia ZL	394	0.66	596:1
Samsung Galaxy S4	320	0	∞
Sony Xperia T	421	0.28	1503:1
iPhone 4S	434	0.53	818:1

The color gamut and color temperature of the Alcatel OneTouch Idol X screen are close to ideal. There is some slight color distortion, but it's fairly minor for a smartphone.

Sound

The OneTouch Idol X smartphone has a strange sound in the player. If you listen to music on headphones, which, in principle, have little bass, then with the Alcatel OneTouch Idol X there will be no bass at all, and the equalizer doesn’t really help the situation. In headphones that have nothing wrong with low frequencies, the bass will be weak and poorly developed. In general, a person who loves music so much that he listens regularly, but not so much that he lacks the capabilities of a “regular smartphone,” is better off taking a closer look at any other model in this price category. Most likely, simply everything will sound better. In addition, with this device you don’t have to worry about going deaf; its maximum volume is low. Although in conversation mode the interlocutor can be heard clearly and well.

Autonomy

The smartphone received a battery with a capacity of 2 Ah. I'm not the most active user, but even in my hands the Alcatel OneTouch Idol X barely survived until the evening. For a 2013 device, especially a flagship one, this is a weak indicator. If you are on the road with a smartphone with constant access to mail, browser and all sorts of social networks, then the battery charge will evaporate in half a day, or even faster. Thus, a test of autonomy in web surfing mode (using only a browser, screen brightness in the middle, Wi-Fi active) showed that approximately 80% of the smartphone’s battery is ready to be discharged in 3.5 hours. Perhaps this is one of those cases when one could forgive a thicker case for the sake of a higher-capacity battery.

Performance and interface

The smartphone demonstrates performance at the level of last year's flagships in benchmarks, and in real life too (gallery with screenshots below). In my opinion, for its price range it is simply wonderful. The smartphone copes with FullHD video, and a heavy load in “working” conditions also does not burden it too much. Although just in the mode of active use and constant switching between tasks, it begins to think and slow down slightly. I had approximately the same sensations from working with Huawei Ascend D2. This is not the performance of a top A-brand smartphone, but it is a very decent performance for a mid-range mobile device.

OneTouch Idol X runs on Android operating system version 4.2. The smartphone interface is closest to the interface used in top-end Huawei devices. There is no separate application menu, there are only six common desktops. There are not enough options for personalization. Thus, desktops can only be added automatically when space on existing ones runs out. The gallery is securely attached to the first desktop; transition effects cannot be changed. If the user is accustomed to a large number of widgets, applications that do not fit will have to be hidden in folders. But everything is drawn very nicely. Perhaps too cute for some grown-up and important guy. Out of the box, the device received a huge number of applications, including many games and useful (and not so useful) tools. In my opinion, the OneTouch Idol X interface lacks practicality and seriousness, but lovers of bright colors and beautiful pictures should be pleased. I suggest looking at the smartphone interface in the screenshots below or in a short video review.

Camera

The Alcatel OneTouch Idol X smartphone is equipped with a 13-megapixel camera. Our experience (one, two, three) has shown that more does not always mean better. The cameras of smartphones from second-tier manufacturers are most often unable to compete with industry giants (the exception, perhaps, is the Huawei Ascend D2, whose images are superior in quality to those taken by the Sony Xperia Z/ZL camera). So Alcatel OneTouch Idol X is not one of the best camera phones of 2013. However, this is not to say that its camera takes downright disgusting pictures. They are good, but if in place of the 13-megapixel module there was a good 8-megapixel module, no one would lose. The camera takes a long time to focus (especially against the background of the Samsung Galaxy S4), and in low light it may not focus at all; it takes a long time to process the image. In HDR mode, your hand can literally get tired of holding the smartphone. The output in most cases is normal photos, but they are weaker than, in particular, the best camera phone (if you do not take into account the Galaxy S4 Zoom) 2013 Galaxy S4, which we just had in our hands and with which we had the opportunity to compare the results . Below are examples of pictures. They can also be seen in a separate gallery on Torba.

Another disadvantage of the Alcatel camera is the almost complete lack of settings.

Competitors

Alcatel OneTouch Idol X's closest competitors are Huawei Ascend D2, Oppo Find 5 and ZTE Grand. They demonstrate exactly the same autonomy (the only exception is the more durable Oppo Find 5) and performance. Everyone received a beautiful IPS display with FullHD resolution. Smartphones (again, all except Oppo) have an almost identical interface. There is a difference in price (Alcatel is cheaper by about 500-1000 UAH), the thinness of the case (again, the advantage is on Alcatel’s side). But Huawei has a better camera and is waterproof, while ZTE and Oppo are equipped with a Qualcomm S4 Pro processor, which is more powerful than the MTK6589. But in general, all devices make the same impression: in terms of reliability, build quality, and capabilities. These are all smartphones of the same level. Alcatel, due to its more attractive price tag, looks more interesting compared to the others, that’s a fact. But let me remind you that it has a rather strange sound in the player. If music is not an important issue for you, then there is a reason not to overpay and stick to a budget solution.

Bottom line

The Alcatel OneTouch Idol X smartphone is not without its shortcomings. Rather, on the contrary, this is a device that has plenty of them: mediocre battery life, not the best camera (in general compared to other 13-megapixel cameras, but decent considering the price of a smartphone), and strange sound in the player. But this is also the most affordable FullHD smartphone today. It's almost impossible to find fault with its screen. Since it is through the screen that the user interacts with the device and through it the attractiveness and convenience of the model is primarily assessed, we can say that Alcatel has done a good job of making an affordable and very attractive smartphone. It will satisfy an audience that does not need top-end performance, but still wants a fairly fast and efficient gadget. In my opinion, the device honestly earns its money. But if you need a flagship device with cutting-edge performance, reasonable battery life and an exemplary camera, then the Idol X will not suit you, you should look at the top devices of A-brands.

4 reasons to buy Alcatel OneTouch Idol X:

• Android 4.2;
• excellent build quality, very thin body;
• almost standard screen;
• delicious price;

3 reasons not to buy Alcatel OneTouch Idol X:

• poor autonomy;
• strange sound in the player;
• Performance is lower than most other smartphones with a Full-HD display (but normal for the money).

The ALCATEL One Touch Idol X smartphone is the manufacturer’s first device with a Full HD screen and a price of less than $400. Idol X is expected to hit store shelves in early November. Together with one of the best Full HD screens, the smartphone is able to offer the user a quad-core 1.5 GHz processor, 2 GB of RAM, the Android 4.2 operating system and, depending on the configuration, 8 GB of internal storage and a memory card slot, or 16 GB and two slots for SIM. In our case, we are dealing with a dual-SIM version equipped with 16 GB of memory.

Let's start with the fact that Idol X is not just one of the most advanced smartphones based on MTK processors today, it also has the thinnest frames in the world. Their thickness is a record 1.75 mm, although taking into account the plastic framing the tempered glass, its size increases to 2.4 mm. However, this does not change the essence, ALCATEL One Touch Idol X remains the owner of the thinnest frames.

At first, you never cease to be amazed how the manufacturer managed to fit a 5-inch display into such a narrow case, and at the same time leave the mechanical keys on the sides and ends in their usual places. But that's not all. In addition to the thickness of the frames, the body itself is thin, only 7 mm, and the weight is 120 g. As a result, the combination of all these little things makes the ALCATEL One Touch Idol X a very unusual and attention-grabbing device. From November, three colors will be available to the user: dark gray, red and yellow. We had the opportunity to use the first option for two months, and the second for several weeks. In the case of a gray case, the user receives a more pleasant plastic rear panel, but a less bright color. In the case of red and probably yellow, the back of the case is also matte, but not as rough as in gray.

As for the rest of the materials, the front part is protected by Dragontrail glass with an oleophobic coating. In terms of reliability, the glass can easily compete with Gorilla from Corning. The glass is framed by a painted plastic frame with a hint of metal. Over time, the paint does not wear off, so you don’t have to worry about this, but the fact that there is black plastic underneath is not at all pleasing, especially if you have peeled off the top layer.

In addition to the 5-inch display, the front panel contains proximity and light sensors, a camera, a slot for the speaker grille, an LED notifying about missed events and battery charge level, as well as three touch keys, from left to right: “Back”, “Home”, "Menu". To call the running applications manager, you need to hold down the “Menu” key; Google Now is called by holding down “Home”. Keys and commands cannot be reassigned. The backlighting of the keys is uniform.

There are slots for microSIM on the left and right sides of the case, symmetrically to each other. Both are covered with magnetic folding curtains. A similar principle of attaching plugs could be found in the Nokia N9 and Nokia Lumia 800 - an elegant and convenient solution. On the right side, under the slot for SIM or memory card, depending on the configuration, there is a double volume key. The button has easy-to-feel edges, so finding it during a call is not difficult. Another use for the volume keys is to wake up from sleep mode. In view of the location of the power/lock key on the right edge of the top end, such care for users looks at least pleasant. In our sample, the keys worked very poorly, in other words, they were glitchy. For example, pressing the volume key could trigger three or four presses at once, and accordingly the volume would decrease by that much. The same applies to increasing the volume. Judging by the comments of some users from the 4pda.ru forum, this problem is also observed in the original model. In this regard, we strongly recommend checking the operation of the keys when purchasing.

Unlike the metal-patterned sides, the keys are glossy and made of black plastic. In addition to the power/lock button, there is a headphone jack on the top edge. At the bottom there is a microUSB connector and a hole for the main microphone.

On the back side of the case, attention is drawn to the protruding camera module framed by a silver rectangle above which you can see the hole for the second microphone at the top, the flash at the bottom, and the inscription FHD 13.1 MP on the right. Below is a metal inscription onetouch, and at the very bottom - ALCATEL with many holes for a multimedia speaker. On the edges of them there are small legs that prevent muffling of the speaker sound.

If we talk about the build quality, then after two months the smartphone body is still the same monolithic, not making any extraneous sounds when squeezed. For a device of this class, this can be considered a compliment. Usually, after a few weeks, most smartphones begin to creak one way or another, this did not happen with the ALCATEL One Touch Idol X.

Operating system and shell

The smartphone runs the Android 4.2.2 operating system and, which is completely unusual for MTK models, has its own interface. The shell resembles a cross between the MIUI interface and what we saw in previous ALCATEL models.

The lock screen can accommodate up to nine widgets (only pre-installed ones are supported). They are all located at the top of the screen. To expand the selected application to full screen, you need to pull it down. If you do not do this, an icon with a lock enclosed in a circle will be displayed at the bottom of the screen. By clicking on it, four shortcuts will appear on the sides of the circle for calling messages, launching the camera, going to dialing or unlocking. The icon itself changes its location depending on how you hold the phone; if you tilt it to the left, it will roll to the left edge. An accelerometer is used to determine the location of the device in space. From the lock screen you can go to the notification panel, which, like all smartphones based on Android 4.2, consists of two tabs: notifications and switches for various modes. You cannot select which of them will be displayed or change their location. The settings menu is divided into five groups. The first contains settings for wireless networks and data transfer. In the second setting of the smartphone. In the third: location, security, language and keyboard, recovery and reset. The fourth is accounts. The fifth contains the date and time, on and off timer, as well as various legal information and information about the device, including a menu for updating software over the air.

The desktop consists of five windows; the number of windows changes depending on the number of installed applications. The one on the far left contains only the image. The following houses several branded widgets. In order to see those that do not fit on the screen, you need to move the list up or down. To edit elements placed on the desktop, use the pinch-to-zoom gesture or hold your finger on a free part of the screen.

The amount of pre-installed software exceeds reasonable boundaries; the good news is that it can be removed and that among the abundance of applications there are programs for working with office documents and an antivirus. It is likely that many of the users will never use them, but those who still need such applications will be grateful for the provision of them for free.

Folders are created by dragging shortcuts on top of each other. To delete an application, you need to hold your finger on it and then drag it to the upper left corner of the screen. By calling the context menu on the desktop, you can remove windows with photo wallpapers and widgets, display hidden applications (you can hide an application using the same action as when deleting, only instead of dragging it to the left corner, drag it to the right).

Among the unusual features, we note a menu with a choice of which applications will display notifications in the status bar, gestures - turning off the sound by turning the smartphone or switching to a new song by shaking, the ability to connect Flash drives (USB OTG is supported), as well as selecting the memory where applications will be installed (valid for the Idol X version with a memory card).

As for the smoothness of the interface, everything is typical here - moving between desktop windows is often accompanied by twitching, but scrolling in applications often works smoothly.

The digital dialing keypad contains letters from the Latin and Cyrillic alphabets. By default, SwiftKey is set as the text keyboard. In most cases the browser is fast. Among the problems noticed, including the original TCL Idol X model, we note the problem with scrolling photos up and down when the smartphone is held horizontally. The sensor doesn't always respond to user input if you're viewing photos at a larger scale and trying to move them up and down.

The operating principle of SIM cards is standard: in standby mode, both SIM cards are available for calls and messages; when accessing the Internet with one of them, both also remain available for calls and messages, but when the former arrive, the data transfer is interrupted; when talking on one of the SIMs, the second will be out of range.

Hardware platform

The smartphone is based on the MediaTek MT6589T hardware platform, equipped with 2 GB of RAM and 8 or 16 GB of ROM. Four Cortex-A7 processor cores operate at a clock speed of 1.5 GHz. The PowerVR SGX544MP accelerator is responsible for working with graphics.

Similar characteristics will be found in Chinese smartphones more and more often, but TCL Communication will remain the first to bring it to the masses in our country.

In terms of performance, the MT6589T shows itself to be a good average, at the level of last year’s flagships, which in itself is not bad, especially considering the Full HD screen. You can get acquainted with the benchmark results below; as for impressions of smooth operation, we recommend that you refer to the previous section. The smartphone slows down when playing games. For example, in Real Racing 3, insufficient fps is often noticeable, especially in scenes with a large number of cars. However, unless you compare ALCATEL head to head with something based on Snapdragon 600/Snapdragon 800, only an experienced user will notice the lack of smoothness. That is, there is slowness, but this can only be understood by switching from or to a more productive device.

In terms of the quality of GPS signal reception, WiFi, 3G operation, ALCATEL One Touch Idol X does not bring any surprises. Although in one thing it is still better than many “Chinese” ones - searching for GPS satellites takes relatively little time, and it finds a smartphone a little more than others.

The volume of the ringing (multimedia) speaker is good, it can be heard under any circumstances. The quality of the speaker is not bad, the preset melodies do not cause wheezing even at maximum volume. The sound in the headphones also has a good volume reserve, but the quality is all standard. The situation can be somewhat improved by using third-party players and headphones, but ALCATEL is not up to par with Qualcomm-based smartphones. The sound volume of the earpiece is average, sufficient for most situations, but without reserve.

Having at its disposal a battery with a capacity of 2000 mAh, the smartphone is capable of quite decent operating time. Under the author's typical workload, I had to charge Idol X every second evening. During this time, 10-15 minutes of calls, 1.5-2 hours of reading social networks, working in WiFi and 3G networks, synchronizing two accounts occurred. Display brightness is automatic. With continuous load, the smartphone owner can count on 4-4.5 hours of screen operation. In two-hour tests, ALCATEL One Touch Idol X showed the following results.

To listen to music, we used a standard player, volume at 12 out of 15 possible, MP3 files with a bitrate of 320 Kbps. In reading mode, all wireless communications are disabled, including data transmission on the mobile network, and the display brightness is set to 50%. Navigation includes getting directions in the Google Navigation app. The brightness is set to 50%, all data communication modules are disabled. When playing a video, the display brightness is set to 50%, the sound volume in the headphones is at level 12 out of a possible 15. The video file format is MKV, resolution 1024x432 pixels, frame rate 24. When playing a video from Youtube, the display brightness is set to 50%, the sound volume in the headphones is at 12 out of 15 possible levels.

Display

There is an opinion that the display is the business card of a smartphone or tablet. The better the display, the more positive emotions the device as a whole evokes. Perhaps this is the key to the success of the ALCATEL One Touch Idol X, since the IPS display (Sharp) used in it is built using OGS technology (without an air gap) and has a resolution of 1920x1080 pixels (441 PPI). The viewing angles are maximum, in this parameter it is not only able to compete with the best displays of HTC smartphones today, but also to be at least as good. The colors are saturated and remain so even with maximum deviation from the perpendicular. The color temperature fits perfectly at 6500K, the color gamut is close to Adobe RGB, and only the gamma curve shows a noticeable oversaturation of light tones, which makes them indistinguishable.

The minimum display brightness is 58.3 cd/m2, the average is 217 cd/m2, the maximum is 420 cd/m2. The first value is too high, and without using applications to adjust the brightness, reading or simply working with the device in complete darkness is tiring for the eyes. A similar drawback on the TCL Idol X was solved by installing the Lux Dash application. It also leads to errors in the light sensor, for example, it does not turn on the display backlight when there is an incoming call, while all functions remain working, including answering a call by moving the lock to the right, but you have to do this at random. Therefore, Idol X users will either have to put up with the application's minor shortcomings or give up using their smartphone in the dark. It is the last factor that does not allow us to give the smartphone the highest possible rating for the screen, because, as we have already said, in everything else it showed itself excellently. Add to all this an ultra-sensitive sensor that can process touches even through cardboard, not to mention gloves, and you can see why we were so impressed with it.

Camera

It is quite possible that ALCATEL One Touch Idol X is the only smartphone not included in the A-brand category that uses Sony sensors. The main module is exactly the same as in - 13 MP Exmor RS ( IMX135). The front camera has a 2 MP sensor ( IMX132) with the ability to record Full HD video. To be fair, we note that the sensor is only one component of image quality. In addition to the sensor, there are also optics, software processing, and here ALCATEL does not show itself in the best way, although the results are superior to most of its classmates. The fast optics (f/2.0) partly help to be better, at least when shooting in poor lighting. You can evaluate examples of camera operation using the examples below. Since there weren't many sunny days during testing of ALCATEL One Touch Idol X, some of the photos were taken by TCL Idol X.

The viewfinder of the camera has a minimalistic design with a minimum of settings. On the right there is a mode switch: photo, video, below it is a large shutter key, illustrating which mode (HDR, panorama) is currently selected. On the left are three icons, from top to bottom: switching to the front camera, settings and flash mode. In the settings, you can enable full screen - photos with an aspect ratio of 16:9 (10 MP) and select HDR or panorama. When recording video, there are no additional settings, only turning on the flash. Video recording can be paused and focused by touch. There is only one complaint about video recording - constant refocusing, which is noticeable even when shooting static scenes.

Results

ALCATEL One Touch Idol X is another proof of how interesting “Chinese” smartphones are becoming. The TCL Idol X model was available for purchase at the end of July. At that time, it was the only smartphone with similar characteristics and capabilities that could be ordered from the Middle Kingdom. But even after three months, the relevance, now ALCATEL One Touch Idol X, does not become less. For 3,100 hryvnia, the user gets a smartphone with one of the best Full HD screens with a record thin frame, a good camera, a quad-core processor, 2 GB of RAM, the ability to choose between a single-SIM version with a memory card slot or a dual-SIM version with a 16 GB drive, high-quality build and good autonomy.

Most readers probably know that the same ubiquitous Chinese are now hiding under the once European brand of Alcatel smartphones - in this case, it is the TCL company, which bought the trademark several years ago and continues to produce and sell devices under this brand. So when buying mobile equipment with the Alcatel label, you need to understand that you are no longer buying a French device, as it was once before, but a Chinese one. However, this in no way detracts from the advantages of Chinese products of this class - modern factory China is quite ready to oppose itself to HTC, Samsung and Sony, which have established themselves as leaders, and our latest reviews of fresh products of high-quality Chinese production can serve as an example of this (the list of such companies includes , primarily Oppo, Meizu, Xiaomi, as well as the ubiquitous Huawei). However, TCL also sells smartphones under its own name, but usually in its home market. By the way, you can also find an “original” model on it, related to the hero of today’s review, and even with a similar name: TCL One Touch Idol X. However, the devices are not exactly exact copies of each other, there are also minor differences between them. However, today we are interested in the European version, which is officially presented on our market, and it is called Alcatel One Touch Idol X.

If we talk about the prerequisites for writing this review, it is worth recalling that we have recently repeatedly addressed the topic of high-quality Chinese mobile products of a high level of performance (Oppo Mirror, Oppo Find 5, Jiayu G4, Meizu MX2, Meizu MX3 and others). Quite recently, we reviewed another advanced Chinese smartphone, sold under the Fly brand (Fly Luminor IQ453), which turned out to be quite high-quality, interesting, but for a “Chinese” - an expensive smartphone. Users themselves on numerous forums compare this model primarily with the Alcatel One Touch Idol X - the devices have very similar characteristics, so the occasional comparison of these two models on the pages of this review will be quite natural and not accidental. It is also worth immediately noting that today’s testing involves a model with support for two SIM cards - 6040D (there is still exactly the same device in nature, only with one SIM card - OT Idol X 6040, but it supports microSD memory cards) .

Contents of delivery

The smartphone goes on sale in a small cardboard package. A rectangular box made of simple, unvarnished cardboard cannot be called chic, but it does not cause rejection either. There is no lurid variety of colors, there is no overload of information either, everything is quite neat and concise.

The box contained: a charger, a Micro-USB cable, a wired headset and some papers. The headphones are equipped with in-ear gel ear pads and a regular, non-noodle-shaped wire that constantly tends to get tangled into a ball. No additional accessories in the form of cases or the like were included in the package of the flagship smartphone at the factory, which is a pity - for a Chinese this device is not so cheap, it would be possible to take care of additional “goodies”.

Appearance and ease of use

In terms of its external characteristics, the smartphone is very good: comfortable dimensions, balanced weight, neat appearance, bright but non-irritating multi-colored back covers, reliable assembly, high-quality materials - all this is Alcatel One Touch Idol X. To be honest, I liked the smartphone much more than the recently reviewed Fly Luminor IQ453: it was clearly made with a bias towards the already popular products of brands such as Apple and Sony, and the Alcatel One Touch Idol X has no claims to anyone else’s account - the design is simple, cheerful, easy to look at, direct and original, and it is precisely this independence from other people’s opinions that inspires respect.

In addition, the device, in terms of the technical arrangement of the case, is not without its own “opinion”: I really liked the way the developers implemented the method of installing the SIM card. More precisely, even two SIM cards: the monoblock case of the Alcatel One Touch Idol X 6040D has one slot-like slot embedded on both side faces, but the method of opening their covers is non-standard. There are no annoying secret buttons and keys here, and you don’t even need a paper clip. The covers of both slots open perfectly without special master keys; you just need to press on one of the edges of the cover, which has a magnetic latch, and it immediately opens unhindered access to the SIM card - a very convenient solution, reminiscent of the first Nokia Lumia devices.

The smartphone fits comfortably in the hand: due to the small width of the case, achieved by thin frames around the screen (no more than 3 mm), very small thickness (7.7 mm) and, most importantly, the non-glossy, matte, rough back cover, the device fits well in the palm and it stays there perfectly. If we take into account the recently increased standards for the size of mobile devices, which have become the norm, then the Alcatel One Touch Idol X model can even be called neat and not too large. It is definitely also quite suitable for a woman’s hand, and the design of this line of smartphones can definitely be classified as unisex.

The materials used are plastic, there is no metal here. There are two types of plastic: matte but hard (without a soft-touch effect) on the back cover and shiny varnished on the sides. The plastic on the sides has the texture of a rough sanded material, but it still feels smooth to the touch and appears shiny due to the layer of varnish.

The back cover is non-removable, you cannot access the battery using standard means, and there is no slot for a memory card at all. More precisely, the microSD slot is provided, as we have already said, in the 6040 version of the smartphone, and in this (6040D) it is replaced with an additional slot for a second SIM card. By the way, it would be appropriate to immediately note that one of the slots can only work with SIM cards from the MTS operator - such a slight injustice. But you can insert any card into the second slot.

In addition to two SIM card slots covered with magnetic covers, there are also a paired volume key on the side faces, as well as connectors: Micro-USB at the bottom, and a 3.5 mm audio output at the top.

There, at the top, there is also a power button, which is a noticeable disadvantage of the device - the body itself is too big for you to comfortably reach up to the power button with the fingers of the hand that holds the smartphone. Probably, it would still be possible to place the lock key on one of the side faces.

The landscape of the rear surface consists of a camera window that protrudes slightly from the plane, a single-section LED flash and a number of small holes in the lower part that make up the speaker grille.

The front panel is entirely covered with scratch-resistant protective glass. It is stated that here, as in Oppo smartphones, it uses not the familiar Corning Gorilla, but a Japanese competing solution called Asahi Glass Dragontrail. Let us repeat that the thickness of the side frames from the edge of the screen to the edge of the body is just under 3 mm, which is a very good indicator. Most users who pick up the Alcatel One Touch Idol X for the first time immediately note this point.

Below the screen there is a block of buttons for controlling the system and applications. The buttons, naturally, are touch-sensitive, have a bright whitish backlight, the duration of which cannot be changed in any way.

There are no rubber pads, protective edges or even a hook for a wrist strap here - we are looking at a typical pampered city dweller, designed for use in “greenhouse” conditions.

And finally, traditionally, about color options: this smartphone, unlike the Fly Luminor IQ453, presented in only one color, black, has a much more diverse range of body colors. At foreign exhibitions there are samples of almost all the colors of the rainbow, but on our market, apparently, only three main ones are officially presented: red, black and yellow. There are no functional differences between models of different colors, and the front panel under the glass is the same black.

Screen

The Alcatel One Touch Idol X smartphone is equipped with an IPS touch matrix measuring 62x110 mm with a diagonal of 127 mm (5 inches), a resolution of 1920x1080 pixels (which gives a very high pixel density of 440 ppi).

The display brightness has both manual and automatic adjustment, the latter based on the operation of the light sensor. The multi-touch technology here allows you to simultaneously process up to 10 simultaneous touches - it seems not very popular, but, nevertheless, a noticeable difference from the Fly Luminor IQ453, which, for some reason, only has five-finger control. The smartphone also has a proximity sensor that blocks the screen when you bring the smartphone to your ear.

A detailed examination using measuring instruments was carried out by the editor of the “Monitors” and “Projectors and TV” sections, Alexey Kudryavtsev. Here is his expert opinion on the screen of the sample under study.

The front surface of the screen is made in the form of a glass plate with a mirror-smooth surface that is scratch-resistant. Judging by the reflection of objects, there is a very effective anti-glare filter, superior in reducing the brightness of reflection to the screen filter of the Google Nexus 7 2013. The ghosting of reflected objects is very weak, which indicates that there is no air gap between the layers of the screen. The outer surface of the screen has a special oleophobic (grease-repellent) coating (very effective, but slightly worse than that of the Google Nexus 7 2013), so fingerprints are removed much more easily and appear at a slower rate than with regular glass.

When the white field was displayed in full screen, the maximum brightness value was about 470 cd/m², the minimum was 80 cd/m². The maximum brightness is quite high, which, given the high efficiency of the anti-glare filter, will ensure excellent readability even on a sunny day outdoors. True, in complete darkness, the minimum brightness may seem excessive. There is automatic brightness adjustment based on the light sensor (it is located to the right of the front camera). In automatic mode, as external lighting conditions change, the screen brightness both increases and decreases. In complete darkness in automatic mode, the brightness is reduced to 108 cd/m² (too much), in an artificially lit office, the brightness is set to 206 cd/m² (acceptable), in a brightly lit environment (corresponding to lighting on a clear day outdoors, but without direct sunlight light) increases to 470 cd/m² (which is to be expected). As a result, this function works adequately, although in the dark the brightness could be lower. At lower brightness, there is some brightness modulation, but its amplitude is small, and the frequency is tens of kilohertz, so the flickering of the screen cannot be visually seen, and the presence of such modulation cannot in any way affect the comfort of working with this smartphone.

This smartphone uses an IPS matrix. The microphotographs show a typical IPS subpixel structure:

The screen has good viewing angles without inverting shades and without significant color shifts, even with large viewing deviations from perpendicular to the screen. For comparison, here are photographs at an angle of approximately 45 degrees to the plane and to the side of the screen, in which the same images are displayed on the Alcatel One Touch Idol X and LG G Pro Lite Dual D686 (it is larger) screens, with the brightness of both screens set to approximately 200 cd /m².

Black and white field:

From this photo we can judge that the Alcatel smartphone maintains color balance and that its brightness drop is slightly less than that of the LG D686.

It can be seen that from this angle the Alcatel colors are better preserved.

When deviated diagonally, the black field brightens quite a bit and acquires a red-violet hue. A photo from the LG D686 shows this for comparison (the set brightness of the white areas on both screens is the same!):

When viewed from a perpendicular perspective, the uniformity of the black field is acceptable. The contrast is high - about 935:1. The response time for the black-white-black transition is 19 ms (10 ms on + 9 ms off). The transition between halftones of gray 25% and 75% (based on the numerical value of the color) and back takes a total of 27 ms. The gamma curve constructed using 32 points did not reveal a blockage either in the highlights or in the shadows, and the index of the approximating power function is 2.05, which is lower than the standard value of 2.2, while the real gamma curve noticeably deviates from the power-law dependence:

Due to the aggressive dynamic adjustment of the backlight brightness in accordance with the nature of the displayed image (in light images the brightness increases, in dark images it decreases), the resulting dependence of brightness on hue (gamma curve) does not correspond to the gamma curve of a static image, since the measurements were carried out in sequential displaying shades of gray on the entire screen. For this reason, we carried out a number of tests - determining contrast and response time, comparing black illumination at angles - when displaying special templates, and not single-color fields in the entire screen. As an example, we present a graph of the transition from a black field to a white field and back for the case of displaying fields in full screen (100%) and when alternating display of black and white fields on half the screen (50/50% line, average brightness does not change and dynamic adjustment does not work ):

You can see how the brightness is adjusted stepwise and that within 0.5 s it does not reach the maximum value.

Color gamut is sRGB:

The spectra show that the matrix filters mix the components with each other to a moderate extent. As a result, visually the colors have a natural saturation.

The balance of shades on the gray scale is not bad, since the color temperature, although higher than the standard 6500 K, but the deviation from the spectrum of a completely black body (delta E) is significantly less than 3, which is considered an excellent indicator for a consumer device. At the same time, color temperature and delta E change little from hue to hue, which has a positive effect on the visual assessment of color balance. (Dark areas of the gray scale can be ignored, since color balance there is not very important, and the error in measuring color characteristics at low brightness is large.)

The screen has a high maximum brightness and an effective anti-glare filter, so you can use the smartphone without much difficulty even on a clear sunny day. But in complete darkness, the minimum brightness may seem excessive, for example, for comfortable reading from the screen. Also, although automatic brightness adjustment changes the brightness in accordance with external conditions, in a not very bright environment it sets the brightness slightly higher than a sufficient level, which will lead to some waste of energy on the screen backlight. The advantages of the screen include a very good oleophobic coating, the absence of flicker and air gap in the layers of the screen, high contrast, excellent stability of black color to the deviation of the gaze from perpendicular to the screen, sRGB coverage and a fairly good color balance. In total, and at the moment, this gives a top-level screen.

Sound

In terms of sound, the smartphone is average. Both speakers produce a fairly clean sound, but without a noticeable presence of low frequencies, mixed with some barely noticeable metallic notes. However, this does not particularly affect the perception of sound during a conversation - the voice of a familiar interlocutor, timbre and intonation remain recognizable. At this point I would like to especially note one point: in their reviews on the forums, users who have already bought an Alcatel One Touch Idol X often complain about some extraneous clicks during telephone conversations. Moreover, it is the interlocutors on the other side of the line who hear them. We carefully checked our copy many times for such clicks: as a result, none of the interlocutors listening on the other side were able to detect any extraneous sounds. The sound is clear, maybe slightly reminiscent of ringing metal, but completely free of foreign “impurities”. Obviously, this is due to a software flaw: perhaps users who discover such a problem should bother updating the firmware or take the device for repair, because this problem, as it turned out, is not widespread.

By the way, the Alcatel smartphone offers the ability to record a conversation from a line using standard built-in tools, which is now extremely rare. Both talking parties are recorded, the recording of the conversation can be listened to by clicking on the icon with the image of a magnetic tape right in the call list opposite a specific call with time and date - everything is organized extremely conveniently, really worthy of praise. In fact, such functionality should be an integral part of any intercom, and even more so a modern smartphone. Surprisingly, such rich functionality is found in Chinese flagship solutions much more often than in generally recognized A-class brands. To be fair, it is worth noting that Fly Luminor IQ453 can also record telephone conversations of both parties. Alcatel One Touch Idol X also has a separate regular voice recorder, which is used only for creating audio notes, and there is also an FM radio.

Camera

Alcatel One Touch Idol X comes standard with two digital camera modules. The front camera here has a 2 MP sensor, takes photos with a maximum resolution of 1792×1008, and can shoot video at a maximum resolution of 720p (the Fly Luminor IQ453 also has 720p).

The main rear camera is equipped with a 13-megapixel module. By default, the camera shoots with a wide aspect ratio, and you must switch to the maximum resolution (13 megapixels) manually, then the pictures are obtained with a resolution of 4224 × 3168. Examples of photos taken in automatic mode “out of the box” are given below with comments.

	Sharpness is generally good, falling slightly towards the left edge of the frame.
	The grass and leaves are worked out quite well. The number plate of the nearest car is clearly visible.
	The branches are quite clear, albeit due to sharpening.
	In the center of the frame, small details are worked out well, although sharpness decreases towards the edges.
	The license plate of the car that is not closest is clearly visible. Noise is processed quite moderately.
	Macro photography is quite acceptable if you know where the focus is.

	Lighting ≈1300 lux. The camera does a good job.
	Lighting ≈460 lux. When the lighting deteriorates, everything is still not bad.
	Lighting ≈240 lux. With a further decrease in lighting, the situation worsens significantly.
	Lighting ≈240 lux, flash. The outbreak hardly changes the situation.
	Lighting<1 люкс. В темноте камера не справляется, но контуры различимы.
	Lighting<1 люкс, вспышка. В данном случае вспышка работает относительно неплохо.

The image quality of this camera is not flagship, but quite decent. Quite standard shortcomings for cameras on inexpensive smartphones are noticeable: aggressive noise reduction in places, noticeable sharpening, a drop in sharpness towards the edges of the frame. The flash is also not very well adjusted and does not allow you to shorten the shutter speed, but nevertheless, it helps in the absence of lighting. The center sharpness of the camera is very good.

Perhaps one of the obvious and few advantages of this camera allows us to classify it as a documentary camera. I would still like to note that the camera shoots quite well, has good sharpness and moderate noise - but only in the central part of the frame, and towards the edges all these advantages are gradually lost.

The camera can shoot video, does it without visible delays or artifacts in the image, and there is only one shooting mode and resolution to choose from. An example of a test video is presented below. Videos are saved in a 3GP container (video - MPEG-4 Visual (Main@L4), sound - AAC LC, 128 Kbps, 48 ​​kHz, 2 channels).

• Video No. 1 (75.9 MB, 1920×1080)

There are very few settings for controlling shooting - mostly the capabilities are left to automation. Shooting can be done either by clicking on a virtual icon on the screen or by using the hardware volume rocker - at this moment it works as a photo button. You cannot take photos while recording video here.

Telephone and communications

The smartphone works as standard in modern 2G GSM and 3G WCDMA networks; There is no support for fourth generation networks (LTE). In general, the network capabilities of the smartphone today are minimal: the 5 GHz Wi-Fi band is not supported, and there is no support for NFC technology either. You can organize a wireless point via Wi-Fi or Bluetooth channels; there is a Wi-Fi Direct mode.

There were no freezes or spontaneous reboots/shutdowns observed during testing. The screen is large, so drawing letters and numbers on virtual keyboards is quite comfortable to control. The layout and location of the keys are standard: switching languages ​​here is done by pressing the button with the image of a globe; there is no separate top row with numbers; you need to constantly switch the layout from letters to numbers and back.

The implementation of working with two SIM cards is standard for the platform: there can be only one active conversation, any of the cards can work in both 3G and 2G modes. In a separate settings section, you can assign default conditions to each SIM card so that, for example, voice communication is always carried out using the first one, and data transmission is always carried out through the second SIM card. In the case of the device officially sold on the Russian market, the first slot is locked to work only with MTS SIM cards, however, users have already learned to bypass this limitation at the software level, just google the topic.

OS and software

The system uses the Google Android software platform version 4.2.2 and a third-party graphical interface, which significantly changes the appearance and introduces noticeable changes to the internal structure and the entire organization of work with the system as a whole. Here, like many Chinese products, there is no application menu as such, and all the icons of installed applications are simply placed on the desktop, like the unforgettable MIUI. Naturally, it is possible to create folders, and the developer himself, in principle, has already “combed” the appearance of the workspace as best he could: most programs are carefully arranged by topic. There is also a whole set of colorful functional widgets - the interface is full of colors, but now it is already becoming fashionable.

A section for managing gestures has been added to the settings menu. Using familiar manipulations, you can, for example, reduce the ringer volume, turn off the alarm clock, or shuffle tracks in the media player. There are a lot of pre-installed programs, there is a full-fledged office suite, a file manager, an antivirus, and even several pre-installed games. In general, the interface is nice and quite flexible in customization.

Performance

The Alcatel One Touch Idol X hardware platform is based on the MediaTek MT6589T single-chip system (SoC). The central processor here has 4 Cortex-A7 cores operating at 1.5 GHz. It is assisted in graphics processing by the PowerVR SGX 544MP video processor. The device has 2 GB of RAM, which is quite modern. The smartphone doesn't have a lot of built-in memory - 16 GB of internal memory nominally and only about 12.7 GB of free flash storage in reality. The smartphone does not support memory expansion using microSD cards (the 6040 model has such support). The problem is partly solved by the ability to connect external devices to the USB port (USB Host, USB OTG). This, by the way, is a significant difference between the Alcatel One Touch Idol X and its main competitor: the Fly Luminor IQ453 does not have the ability to connect external devices.

Based on the data obtained during testing, the Alcatel OT Idol X system demonstrated quite expected average performance indicators, at the level of other devices we have previously tested, which operate on the same platform. In nature, there is also a regular version of MediaTek MT6589 with an operating core frequency of not 1.5 but 1.2 GHz (on which, for example, the Oppo Mirror R819 is based), and a comparison of the results of these platforms showed a natural advantage of the MT6589T version. Well, a comparison with its closest competitor, Fly Luminor IQ453, revealed an almost absolute coincidence of results, which is logical, since both devices are built on the same platform.

Test results in MobileXPRT, as well as the latest versions of AnTuTu 4.x and GeekBench 3:

As for benchmarks for assessing the speed of the javascript engine, you should always make allowance for the fact that their results significantly depend on the browser in which they are launched, so the comparison can only be truly correct on the same OS and browsers, and this is possible during testing not always.

Playing video

To test the omnivorous nature of video playback (including support for various codecs, containers and special features, such as subtitles), we used the most common formats, which make up the bulk of the content available on the Internet. Note that for mobile devices it is important to have support for hardware video decoding at the chip level, since it is most often impossible to process modern options using processor cores alone. Also, you shouldn’t expect a mobile device to decode everything, since the leadership in flexibility belongs to the PC, and no one is going to challenge it.

Format	Container, video, sound	MX Video Player	Standard video player
DVDRip	AVI, XviD 720×400 2200 Kbps, MP3+AC3	plays normally	plays normally

¹ MX Video Player only played sound after switching to software decoding or Hardware+; The standard player does not have this setting

We did not find the MHL interface, like Mobility DisplayPort, in this smartphone, so we had to limit ourselves to testing the output of video files on the screen of the device itself. To do this, we used a set of test files with an arrow and a rectangle moving one division per frame (see “Method for testing video playback and display devices. Version 1 (for mobile devices)”). Screenshots with a shutter speed of 1 s helped determine the nature of the output of frames of video files with various parameters: the resolution varied (1280 by 720 (720p) and 1920 by 1080 (1080p) pixels) and frame rate (24, 25, 30, 50 and 60 frames/ With). In tests we used the MX Player video player in Hardware. The test results are summarized in the table:

File	Uniformity	Passes
Screen
watch-1920x1080-60p.mp4	Fine	a lot of
watch-1920x1080-50p.mp4	Fine	a lot of
watch-1920x1080-30p.mp4	Fine	No
watch-1920x1080-25p.mp4	Fine	No
watch-1920x1080-24p.mp4	Fine	No
watch-1280x720-60p.mp4	Fine	a lot of
watch-1280x720-50p.mp4	Fine	a lot of
watch-1280x720-30p.mp4	Fine	No
watch-1280x720-25p.mp4	Fine	No
watch-1280x720-24p.mp4	Fine	No

Note: If in both columns Uniformity And Passes“green” ratings are given, this means that, most likely, when watching films, artifacts caused by uneven alternation and frame skipping will either not be visible at all, or their number and visibility will not affect the viewing comfort. "Red" marks indicate possible problems associated with the playback of the corresponding files.

The intervals between frames (or groups of frames) alternate slightly unevenly, and in the case of 50 and 60 fps files, some frames are skipped. When playing video files with a resolution of 1920 by 1080 pixels (1080p), the image of the video file itself is displayed one-to-one, exactly along the border of the screen. The brightness range displayed on the screen corresponds to the extended range (that is, the range 0-255). And since most video files are encoded in the video luminance range of 16-235, the white color of such video files appears as light light gray on the screen of this smartphone, and the black color appears as dark dark gray, which obviously does not improve the image quality.

Battery life

The capacity of the lithium-ion battery installed in the Alcatel OT Idol X is small by today's standards of 2000 mAh. However, all ultra-thin Chinese models that we have tested recently are equipped with the same amount of energy - this applies to both the Fly Luminor IQ453 and the Oppo Mirror. The battery here, as already mentioned, is non-removable, so you cannot remove it, replace it, or take a spare one with you on the road.

Continuous reading in the FBReader program (with a standard, light theme) at a minimum comfortable brightness level (brightness was set to 100 cd/m²) lasted about 10 hours until the battery was completely discharged, and when continuously watching videos from YouTube in high quality (HQ) with The device lasted less than 7 hours at the same brightness level via a home Wi-Fi network - these are average figures. In 3D gaming mode, the smartphone lasted just over 4 hours.

Bottom line

Currently, the official price of Alcatel OT Idol X is set in our market at around 14 thousand rubles. The competitor's price is slightly higher: Fly Luminor IQ453 now costs 15 thousand rubles, but it is difficult to find anything that would make it more preferable in comparison with the hero of today's review. Perhaps a larger amount of built-in memory. Otherwise, it turns out that Alcatel OT Idol X looks better in all respects and is even cheaper. Of course, the list of competitors is not exhausted by these two models, however, most of them are characterized by either much worse characteristics (most often the screen is not Full HD) or a significantly higher price - 20 thousand and above.
