As you know, many Windows tablets cannot boast the same long battery life. battery life, which we are used to on tablets with the Android operating system on board, so we have to charge them much more often.

At the same time, we constantly have to monitor the battery level of our devices, and it would be nice if our Windows tablet or laptop itself gave us signals when the charge of its battery during operation (or recharging) reached certain levels.

Currently, there are several theories as to what levels should be kept within the battery charge of a tablet or laptop.

One of them says that in order to ensure the longest possible service life, you can keep your laptop or tablet constantly connected to charger and most importantly - do not let the battery drain too much.

The second theory says that it is best to keep the charge level lithium battery ranging from 40 to 95 percent.

In both cases, we need to constantly monitor the level of discharge or battery charge of our devices and not allow it to go beyond the established limits.

Today I want to tell you how you can automate this process.

How to set a low battery warning Windows batteries tablet or laptop

Low battery alerts are easy to set. To do this, you need to do the following:

1. Go to "Control Panel" -> "Hardware and Sound" -> "Power"

2. Open the current power plan and click on "Set power plan"

3. Click on "Change advanced power settings"

4. In the window that opens, open the "Battery" item by clicking on the "+" next to it

5. Here you can set the level, when the battery is discharged to which, you will receive a corresponding warning.

Warning when the battery of a tablet or laptop reaches a certain level

With a warning that the battery of a tablet or laptop reaches a certain level when it is charging, things are a little more complicated.

Here we need a special script (a set of commands), which you can create in the Notepad application by simply copying the following text into it:

set oServices = oLocator.ConnectServer(".","root\wmi")

set oResults = oServices.ExecQuery("select * from batteryfullchargedcapacity")

for each oResult in oResults

iFull = oResult.FullChargedCapacity

next

while(1)

set oResults = oServices.ExecQuery("select * from batterystatus")

for each oResult in oResults

iRemaining = oResult.RemainingCapacity

bCharging = oResult.Charging

next

iPercent = ((iRemaining / iFull) * 100) mod 100

if bCharging and (iPercent > 95) Then msgbox "Battery charge: " & iPercent & "%",vbInformation, "Battery Monitor"

wscript.sleep 300000 "5 minute battery poll interval

wend

This script, authored by John Howard, polls the battery level every five minutes, and when it reaches 95 percent, it displays sound signal and the corresponding warning.

You can set the charge level for the warning in the third line from the bottom (iPercent > 95), changing 95 to the value you need, but not more than 99%.

After you do this, save the script to your desktop under any name, but always with the .vbs extension

For example: battery.vbs

That's it, now if you run this script, then when the battery level reaches the level you set, it will give you a warning about this. If you want the script to automatically run every time you start your device, put it in the startup folder .

You may have noticed that in the script above, you can set the battery level to no more than 99%. But what if we need to be notified when the battery is fully charged to 100%?

In this case, you can use a script I created based on John Howard's script:

set oLocator = CreateObject("WbemScripting.SWbemLocator")

set oServices1 = oLocator.ConnectServer(".","root\cimv2")

set batItems = oServices1.ExecQuery("Select * from Win32_Battery")

while(1)

for each battery in batItems

ischarged = battery.BatteryStatus

next

if (ischarged = 2) or (ischarged = 3) Then msgbox "Battery is charged!",vbInformation, "Battery monitor"

wscript.sleep 300000 " 5 minutes

wend

Next time we will talk about why some tablets lose their battery quickly in sleep mode, as well as how to deal with this problem.

Android is indeed an excellent operating system, but at the same time it has its drawbacks. Some of them are congenital and only have to be put up with, others can be eliminated quite easily. In this article, we have collected some of the most common Android problems and tips to fix them.

Increasing battery life

This is still one of the biggest disadvantages of mobile gadgets. Manufacturers continue to produce smartphones that last less than one business day. It is clear that the design features of modern batteries and the ever-increasing needs of devices have entered into a deep contradiction. However, there are ways to solve this problem.

• When buying a gadget, please close attention to battery capacity. Yes, you may have to pay a little more for this pleasure, but freedom from socket addiction is worth it. Pay attention to the MAXX line from Motorola, a series samsung galaxy Note and other devices that can show outstanding survivability.
• Buy an extra battery. If you do not currently have plans to buy new phone, it is better to purchase an additional battery. It can be either just an additional battery, or replacing an existing one with a more capacious one.
• Reduce App Power Consumption. If you are seeing that the battery is running low even when you are not using your phone, then it's time to look into applications that work in background. For this, it is good to use the recently described by us or the tips from this one.
• Use Airplane Mode. If the battery indicator shows less than 10%, then there is no time for fine-tuning. Just activate the flight mode and you will extend the life of the device for several hours. The same can be done at night if you do not expect important calls. Turning off all communications reduces energy consumption to almost zero.

Get rid of junk software

Manufacturers and sellers install a huge amount of unnecessary commercial software for many device models. And this can turn into a real problem. The software imposed on you not only takes up space, but also eats up system resources, consumes the battery, and simply interferes. Fortunately, there are ways to fix this.

• Disable them in system settings. Most of these programs have the status of system programs and cannot be so easily removed. If you don't want to root your device, you can almost always go into the settings and disable the programs you don't need, as shown in the illustration above.
• Get root and remove junk. Getting superuser rights is not such a terrible procedure. You can use or article. After that, you can completely remove or only freeze the programs of your choice. For this there is a large number of special utilities, the most popular being Titanium Backup and RootAppDelete.

Hide or eliminate branded shells

Many manufacturers use branded launchers on their devices, which, however, may not be very convenient or consume too much system resources. You can solve this problem as fine tuning the corresponding shell, and its complete replacement.

• Return to Stock Android as much as possible. If you want to solve the problem "with little bloodshed", then you will have to individually select and replace the launcher, keyboard, dialer, calendar, and so on with real google apps. How to do it on Android example 4.4 we talked about in these articles (,). Pay attention also to third party applications, which sometimes differ in even greater capabilities and low consumption of system resources. You can start, for example,.
• Flash third party firmware. If you are leaning towards a more radical and complete solution, then you will have to reflash your gadget with one of the third-party firmware. Such developments, as long ago, have come out of children's diapers and provide quite stable, convenient and safe operating systems.

Turn off annoying notifications

As a rule, almost all programs have a corresponding section in the settings. Just do not be lazy to look for options that are responsible for what, when and how often the application will display in the notification bar. This, by the way, can further reduce battery consumption.

There is also a more radical way. In Android 4.1 and above, you can open the application page in the system settings and disable all notifications from it altogether. Just uncheck Show notifications as shown in the picture above.

Set the correct orientation for each application

Some programs look great in portrait orientation, others in landscape. To put this under control, use the Smart Rotator utility, which provides us with a single interface to manage these settings and allows you to choose which applications will use automatic rotation and which will always adhere to vertical or horizontal orientation. It is especially good to use this program on tablets.

Do you have problems with your laptop battery and need to keep a close eye on it? By Windows default displays low battery notifications only when it drops to 10% and 5%.

How to set notifications for other battery levels in a windows 10 laptop (similar in other versions)?

If your battery is draining fast, it's worth editing your notifications to display an alert when the battery drops to 50% and 25%.

Then you will be able to react faster and better control the rate of battery depletion. How to do it?

Low battery notification settings

The appropriate setting can be found in your meal plan options. To change them, go to "Control Panel", then to "System and Security" -> "Power Options".

Meal plans will appear in the list. Click the "Scheme Settings..." link next to the active plan (we can change the settings later for each plan). In the new window, go to the "Change advanced..." section.

The Power Options window will appear with a list of settings in the drop-down menu. Next, go to the very bottom and expand the "Battery" section.

Then we expand the "Notification of low battery" field, and look that in both cases it is set to "Enable".

Then we deploy two fields: a low level and an almost complete discharge. In both of these options, you can change the default charge levels.

Windows systems may have different notification settings, but you can set the low level to 50% and almost full discharge by 25%.

Now you're done - the system will give you a notification after exceeding the threshold charge level that you specified. Good luck.

On my Lenovo laptop Y410 I installed Windows7. I used to have Windows XP. In XP, I got a low test notification when my battery reaches 10% life. In I even set the low notification notification, but still it doesn't notify me when the battery reaches 10% life and when it reaches the critical level of 5% it automatically goes to sleep. It annoys me.

Can anyone tell me why he doesn't notify me when he reaches low testosterone? I use a balanced diet. Low test tone notification is enabled and battery level is 10%. The critical battery level is 5%.

UPDATE: During the internet search problem, I kept the laptop on battery and every minute I watched the battery level. Previously when I used Windows XP it lasted 3 hours with dim light. Now, in Windows 7, it lasts one hour and as some other user asked a question saying battery life suddenly drops from 26%-5% (question here) even my laptop right after I saw 26%, it went into sleep mode According to the action of the critical level. I admit that some things are similar to this user, such as my battery is a year old. But I don't understand why it started all of a sudden when I switched to Windows 7 from XP. This is a little doubtful for me. Should I accept the solution given in this question, or is there another thing I should try?

Here are some more reasons. There was a bug related to Vista. However, some issues are related to the BIOS. So try updating it. Another solution is to remove the battery and clean the contacts with a pencil eraser. One person said that when he or she changed the action Critical Battery on the " Shut down" from " Hibernate”, a low battery notification appeared.

EDIT: The notifications you can set are just battery [level, notification] and spare battery*[level]. Win7 missing critical battery notification [only level and action].

If, for example, you set a low battery battery to 6% and a critical battery to 3% [the lowest bypass is accepted], you can set a spare battery to 4% to act as the last power connection ditch warning until The battery operates without any additional warnings.

[* The battery backup level is not associated with any action other than the warning alert - "Critical Battery Warning. You are now in standby mode. Your battery is very low (4%), please connect immediately. No, your computer will automatically go into hibernation soon. "]

So, to sum up - your spare battery level should be HIGHER than the rest.

Google annually adds many settings and features to the Android operating system, many of which are hidden from the eyes of ordinary users. This was done on purpose, but with good intentions. The American corporation believes that if an inexperienced owner of some inexpensive Android smartphone accidentally activates certain important settings, then his device may start to work more slowly or discharge much faster, therefore, right out of the box, all smartphones based on Google's OS have only basic activated functionality, but this is very easy to fix.

Although every year all smartphones work longer on a single battery charge, largely due to better software optimization for hardware, but hidden setting in all Android smartphones, it significantly increases battery life, and absolutely anyone can activate it now, since it is definitely available in any custom firmware and in all models of mobile devices.

All smartphones based operating system Android has an incredibly large margin of power, which is simply redundant for dealing with simple everyday screens. It's like driving a car, sometimes pressing the gas to the floor, and then slowing down again. In the case of smartphones, it’s not gasoline that runs out faster, but the battery charge. To increase battery life mobile device you need to open "Settings", then go to the "Battery" section.

In the "Battery" section in the upper right corner, three vertically located dots should be visible, which you need to click on. In the menu that appears, you will need to select "Power Saving Mode", and then activate it. As a result, processor performance will be reduced, which will allow up to 50% increase in battery life on a single battery charge. This feature is available in all smartphones and tablets running Android 5.0 Lollipop and higher.

To achieve even greater effect, the editors of the site recommend installing the “Doze-energy saving” application, which significantly increases the battery life of all Android smartphones, since a lot of charging is “eaten up” by processes running in the background that the user does not even see. After installing it in the list, you need to select only those programs and services that should continue to work normally.

It is worth choosing the most basic messengers, mail clients and other major programs that should receive notifications in real time and not with a delay. This program works in such a way that all processes that run in the background and consume battery power are automatically frozen. This does not harm them or the data stored in them in any way, and using this application allows you to significantly increase battery life up to 40% of the standard. This is especially noticeable at night, when without this program the smartphone battery will be discharged by 10-12%, and with it only by 5-6%.
