Your phone isn't charging? So what, it’s a small problem. You still have a functional device in your hands, which just decided to play around. The main thing is not to panic, find out, at least quickly, the cause of the malfunction and fix it immediately. Don't know how to do this? Then you have come to the right address. We'll tell you why your phone won't charge and what you can do about it at home.

Why is my phone not charging?

The phone does not charge for only one reason - the device’s battery cannot receive energy from the outlet. Simply put: some obstacle has appeared in the path of electricity, breaking the power circuit. And this obstacle could be:

• Cable or charger. The first may refuse to conduct current, and the second may simply break and not supply voltage to the cable.
• A phone connector that easily becomes clogged with dust and other debris that interferes with normal contact between the cable connector and the smartphone port.
• Phone or battery board, or rather controllers that monitor the charge level.
  A worn-out battery that is unable to hold the required amount of charge.

Now that you understand why the phone is not charging, all that remains is to find out how to eliminate this or that obstacle.

Cable and charging problems and how to fix them

This problem is usually encountered by owners of old devices. Over the course of a long and faithful service, both the charging and the cable itself may wear out. Moreover, this failure is diagnosed very simply: the user inserts the charger into the socket, connects the phone to the cable and sees that it does not even think about charging.

What to do in this case:

• First, remove the cable and connect it to the USB port of your computer. If your smartphone starts charging, then you need a new charger.
• Secondly, try charging your smartphone using a new cable. If your phone battery shows signs of life, you will have to throw away the old cable.

At the same time, do not forget that a new charger can bring another problem into the house - a loss of charging speed. This usually happens when, instead of an original and expensive charger, they buy something more affordable. And if your smartphone charges slowly after replacing the charger, then you are better off replacing the current charger with a branded module. The fact is that some chargers can generate significantly more voltage (and current) than a regular USB port.

By the way, it happens that the iPhone does not charge due to the absence of a chip in the cable. Cunning Apple engineers came up with a mechanism for identifying peripherals, including chargers, using a special chip, installation of which is possible only with the consent of the Apple corporation. Therefore, non-original cables and chargers without a chip simply will not be perceived as functional by the phone itself.

Solving problems with the connector

If you have changed both the charger and the cable, but there is still no use, then the obstacle is most likely the phone port. What to do in this case:

• Unplug the charger and turn off the phone.
• Remove the battery and turn on a bright desk lamp.
• Hold the connector up to the light and examine it carefully. Usually a lot of debris gets into the phone port and you will have to remove it using a needle, toothpick and syringe.

The first tools can be used to pry up pieces of debris and pull them out. A syringe with alcohol will be useful if you need to wash out deposits of dust and dirt in the connector. In this case, alcohol is simply injected into the contact area of ​​the connector under pressure.

After rinsing the port with alcohol and gently cleaning it with a needle or toothpick, you can replace the battery and try to charge the phone again.

Problems with the board and battery

Have you changed the cable and cleaned the port, but your phone still doesn't work? In this case, you will face a more serious breakdown. Usually, if the smartphone battery does not charge, and the cable and port are 100 percent working, the source of the problem will be the smartphone board or battery.

And if you checked the cable on another smartphone, and the phone’s port allows data transfer (synchronization with a computer works), then your device will have to be taken to a service center. This problem cannot be solved at home. Just try resetting the settings using the “reboot” button or a combination of “hot keys” pressed at the start. But even in this case, you will not have any guarantees to restore the charging process.

Probably every car owner has encountered power supply problems. Even on foreign cars, not to mention domestic cars, it happens that the generator does not charge the battery. This is a serious problem. Someday, at the most crucial moment, the car simply won’t start because the battery has not been charged properly. But often we need a car right now.

Theory of the issue

While the car is moving, a dead battery receives a charge voltage of 13.6 to 14.2 V. For the correct and stable operation of all systems in the car, these voltages must be maintained until the engine starts and the crankshaft rotates. Together with the motor, torque is supplied to the generator through the drive belt. At this moment, an amount of energy is generated that will be sufficient for the stable functioning of all systems and to maintain a charge on the battery.

The internal combustion engine can operate in different modes. At the same time, the number of revolutions on the crankshaft changes. The number of revolutions of the pulley also changes, this leads to an increase in the voltage produced by the generator. To maintain a level of 13.6-14.6 V in the on-board network, there is a special relay in the excitation circuit. It regulates the voltage level. When the rise exceeds the normal value, then the current supplied to the winding will decrease. At the same time, the magnetizing force of the rotor also decreases. This leads to a decrease in output voltages.

If the generator does not charge, then in most cases the reasons must be sought in the excitation circuits, as well as in the output voltage circuits from the generator to the battery. But this is not always the case. Sometimes problems are related to the generator itself.

When the driver turns the key in the lock, the relay in the ignition system also starts at the same time. “Plus” flows through the relay and fuse in the mounting block. Next, the voltage passes through the on-board network, reaching the battery charge lamp and charge sensors. It then passes through diodes, relays, elements in the mounting block and finally to the connector in the generator. There, electricity comes to the relay-regulator and, passing through brushes and slip rings, enters the exciting winding.

As the crankshaft speed increases, the phase stresses increase. Then, through a diode block, they increase the voltage on the excitation winding and on the diode of the control lamp. When the output phase voltage reaches 12 V on both terminals, the voltage will be equalized. Due to the lack of voltage difference, the control lamp will go out. In this case, the generator produces a voltage that is higher than 12 V.

How to determine that the generator is not charging the battery

The easiest way to check that the generator is not charging (VAZ-2110 is no exception) is by looking at the dashboard. There is a control lamp on it. Classic VAZ models also have a voltmeter. The arrow should be in the green zone, and the control lamp should be in normal mode (when everything is in order, it does not light up). If this is not the case, then charging does not occur. It is worth considering the problem in detail.

A better and more accurate way to help determine that the generator is not charging is to check the voltage at the battery terminal with a multimeter. If there is a charge, then the device will show from 13.6 V to 14.6 V. If there is no charge, then the readings will be from 12 V and below.

Typical reasons

There are several reasons that lead to such a malfunction. Let's look at them and find out how to eliminate them.

Generator overload

If the battery is charging, but the voltage is insufficient, it means the generator is overloaded. This is facilitated by the installation and connection, in addition to standard electrical equipment, of various gadgets that require electricity. The generator is operating at the limit of its capabilities.

Modern drivers love various car tunings. Thus, serious music systems, powerful lighting and other equipment are installed. Someone also increases the battery power. So, with a 70 Ah battery, the standard VAZ generator cannot fully charge it. It just doesn't have enough power. As a result, the generator provides little charge.

Poor or weak contact

Contact is weakened if the brushes and slip rings on the rotor are covered with dirt and oil. The culprit is also considered to be the shrinkage of the spring, which puts pressure on the brushes. Often the brushes get stuck. All this causes an increase in excitation resistance, and sometimes even a circuit break.

It helps to cope with this problem by cleaning dirty elements with a rag pre-moistened with gasoline. If the brushes are very worn, they are replaced. Oxidized rings are cleaned with glass sandpaper.

Breaks in the winding

If there is a break in the excitation winding, then the generator does not charge. This is determined simply. It is enough to touch the generator with your hand. If the winding breaks, the device will heat up. To diagnose more accurately, the end of the excitation winding is disconnected from the brush and connected to a terminal on the generator. The measurement is carried out using a multimeter from the battery.

If there are breaks, the multimeter will not show anything. If a signal lamp is used instead of the device, it will not light up. In order to find the problematic coil, wires from the battery are connected to each of them in turn. If the break is inside, the coil is replaced. External breaks are removed using a soldering iron.

Short circuit to the rotor housing

In the event of this malfunction, the entire field winding will be closed and the generator will not be able to operate. Often, short circuits to the frame occur in places where the ends of the winding are connected to the slip rings on the rotor. You can check this using a 5 V lamp. To check, the wire should be connected to one of the slip rings, and the second to the rotor core or its shaft. In the event of a short circuit, the lamp will light up. This generator is faulty. You can insulate the short circuit or replace the winding completely.

Short circuits in the phase winding on the stator

Here is another reason why the generator does not charge. It may short out due to the destruction of the insulation between the turns in the generator stator coils. The generator will heat up and will not charge the battery enough, since it only provides full voltage at high engine speeds.

Short circuit of the stator to the housing

As with other short circuits, the device will become very hot. The noise during its operation will increase and the power will decrease.

You can check the malfunction using the same light bulb or multimeter. One terminal of the lamp is connected to the core, and the second to any of the winding terminals. If there is a short circuit, then the lamp will light up. A damaged coil cannot be repaired. Only replacement can solve the situation.

The positive terminal shorts to the body

If the generator does not charge the battery, this may be the reason. In the event of this malfunction, the device will not only heat up, but also breakdowns on the diode rectifier unit are possible. As a result of the breakdown, the battery will short-circuit. As a result, there is a serious risk of battery failure.

Mechanical breakdowns

If the generator does not charge, the reasons may be not only electrical, but also mechanical. In the first place among the malfunctions is a stretched drive belt. This can be easily diagnosed - the pulley will become very hot.

There is also no charging at a sufficient level. Additionally, it is recommended to inspect the device, terminals, and wires for poor contacts, breakage and other mechanical damage.

Algorithm for finding the cause

We looked at typical faults. But it is important to find the main reason. If the car has standard equipment and there are no abnormal energy consumers, then you can begin to diagnose the generator directly. If there are additional consumers, it is better to turn them off. In this case, it must be disconnected physically, from the on-board network.

First, measure the current output with the motor turned off. Here it is important to find out whether there is energy consumption when the engine is not running and the ignition is turned off (the key is also removed from the lock hole). It is important that even the alarm is turned off during the measurement process. Most domestic cars exhibit small current leaks. It always gets stuck somewhere “to ground” (that is, the negative wire is in contact with the body). But often they are not able to completely discharge the battery even in two or three weeks.

Next, all consumers are connected and the leakage is measured in the same way with a multimeter. If it is large, then the reason should be sought not in the generator or battery, but in one of the devices in the on-board network. If no leakage currents are detected at rest, then most likely the VAZ generator is not charging. We have already discussed the reasons.

Conclusion

So, we found out why the generator in the car does not charge. If problems associated with current leakage are detected, you must immediately begin to find the breakdown and fix it. The generator is the main part of the vehicle's electrical system. Like the human heart, it provides energy to all instruments and devices. The generator must be treated with care - install non-standard devices and acoustics wisely. And if problems arise, it is better not to put off repairs “for later.” Now novice car enthusiasts know how to check whether the generator is charging or not. This will help in self-repair.

Greetings to all motorists! Unfortunately, a modern car is not a trouble-free thing, and periodically throws up surprises. One of them is that the battery is not charging. Sometimes this problem is easily solved, but sometimes the help of specialists is required. But before treating the consequences, you need to find the cause. So let's look at them.

Reasons why the battery stops charging

There are several reasons why the battery is not charging:

• stretching or breakage of the generator belt;
• oxidation of battery terminals;
• oxidation or breakage of generator wires;
• problems with the generator.

Let's take a closer look at how to diagnose and, if possible, eliminate these causes. Although, sometimes the problem may be in the battery itself. Therefore, when the charge lamp on the dashboard is on, and a visual inspection did not help to find the fault, you can use the method of elimination.

To do this, you will need to find a working battery and replace it with yours. In this case, the size of the batteries does not matter. If the charge goes on, then the problem is in the battery, if not, most likely there is a problem with the generator.

The battery may stop charging for various reasons. But most often this is sulfation of the plates, which occurs after deep discharges, or from old age. By the way, in advanced cases, electrolyte replacement may be required. In general, to combat sulfation there are several methods based on cyclic charging and discharging of the battery using a charger.

Often the reason for the lack of charge is oxidation of the terminals. This is very easy to determine. You need to open the hood and look at the current output contacts. If they are covered with a strong mushy coating, it means that the terminals have oxidized.

This usually happens when cracks appear on the battery case in the area of ​​the positive and negative terminals. Electrolyte vapors come out of them, come into contact with lead and oxidize, forming an unpleasant coating.

The issue is resolved in several stages:

• the terminals are thoroughly cleaned;
• the cause of oxidation is determined and eliminated;
• The terminals are dressed and a special anti-oxidation compound is applied to them.

Most often, oxidation problems occur in inexpensive batteries, as well as in cases where the battery is often removed from the vehicle. Simply when removing the terminals from the battery terminals, they can be loosened.

When oxide appears, one more point needs to be taken into account - The electrolyte level in the banks may have dropped below level. Therefore, you should check it and, if necessary, raise it. At the same time, remember that you need to add distilled water to the battery.

If there is a problem with the belt, charging from the generator will not take place.. Therefore, during a visual inspection, it is advisable to carefully examine it. Even if the belt is intact, it does not mean that it is in order.

Typical problems:

• belt break;
• loosening the tension;
• microcracks;
• pollution.

If the belt breaks, everything is clear - it needs to be changed. But, as stated above, he could simply stretch out. Therefore, we check its tension, and at the same time its cleanliness. If it is wet or covered in oil, when the pulleys rotate, the belt may slip. As a result, the light on the dashboard is on, and the generator does not work.

Problems in the on-board circuit

Along the way, you need to check the integrity of all wiring. Sometimes problems can lie precisely in the flight chain. We start from the generator:

• all connections must be well tightened;
• There should be no oxide and especially soot.

You should immediately remove the brushes from the generator. Their development is another common problem. Not allowed:

• different output, i.e. when one is longer than the other;
• The brush size is less than 5-7 mm.

In addition, you need to check the weight on the body. Poor contact in this place is another reason why the battery charge lamp may light up.

Generator malfunction

A car generator can throw up surprises from time to time. Unfortunately, brush wear is not the only reason why the charge check light may be on.

Possible malfunctions:

• damage to the regulator relay;
• problems with the diode bridge;
• broken stator winding.

Determining that something is wrong with a generator is quite simple. For this you will need a multimeter. In this case, you can immediately determine how charged the battery is. If the readings on a switched off engine are 12.6-12.7V, this indicates a full charge. 12.2-12.4 – charging about 50%. Less than 11.7 – the battery is completely discharged.

Methods for checking the generator:

• when the engine is started, the voltage at the battery contacts should be about 14.7V. If it is very different, there is a problem with the generator;
• If you remove the terminal from the battery while the engine is running, it should continue to work. Otherwise, there is a malfunction with the generator;
• When the car is running, there is a clearly noticeable lack of energy.

To accurately diagnose and cure generator malfunctions, you need to have at least minimal knowledge of electrical engineering. If they are not there, it makes sense for you to seek advice from a specialist - you will definitely save time.

So, the problem of lack of charging can be either the most trivial, which can be easily fixed with your own hands, or more serious. To eliminate malfunctions arising from improper operation, you need to follow two rules.

Firstly, periodically charge the battery, and secondly, monitor its external condition. And don’t forget to carry a spare alternator belt and brushes with you.

That's all, I hope the article was useful.

What to do if your Android smartphone is not charging, and what could cause this?

Almost every user of a mobile gadget, be it a smartphone or a tablet, has found himself in a situation where the gadget does not charge, does not see the connected charger, or incorrectly displays the battery charge. Before taking your phone to a service center, you can try to troubleshoot problems at home. First you need to find out what exactly the problem is.

After a strong discharge?

If problems appeared after the device was discharged to zero, read. If the methods suggested in it do not help, you will have to spend a little time troubleshooting.

Charger cable

The cable is one of the most vulnerable elements of the charger: it can burn out, break at the bend, or stop transmitting a signal. Instead of buying a new cord outright, try charging your phone using a different compatible cable. Perhaps replacing it will be enough to solve the problem.

power unit

If the cable turns out to be working, but the charger still does not perform its function, check the operation of the power supply on another smartphone or, if possible, measure the voltage at the charging output connector using a voltmeter. If there is no voltage, the unit is faulty and must be replaced.

Contacts

Another common cause of problems with charging a smartphone or tablet is clogged contacts. Dust and other small debris may get into the charger connector and the phone itself. The contacts can be cleaned with a soft brush, and you can also try to “lift” the fasteners inside the connector with a toothpick.

Attention! These actions are dangerous and must be performed carefully and competently. Remember that all responsibility for the gadget lies on your shoulders.

Battery

If everything is fine with the charger and its components, the problem may lie in the battery itself. If your smartphone has a removable battery, remove it and inspect it for damage or deformation. If it turns out to be faulty, you need to purchase a new battery. Read the material about verification methods at the link.

Software

If the smartphone firmware is unsuccessful or an update is installed, the system may malfunction, including during the charging process. There are several ways to fix this:

• Use applications to optimize the system and remove accumulated garbage (CCleaner, Clean Master, Smart Manager).
• Do a flashing.
• Resort to a system rollback through the Recovery utility, if you used it to create backups, or reset to factory settings.

Battery calibration on Android

If your mobile device sees charging, but charges slowly or displays incorrect battery indicators, you can try calibrating the battery (see brief instructions below).

1. Completely discharge the gadget until it turns off. When you try to turn it on, it should turn off immediately.
2. If the battery is removable, remove it from the device and keep it separately for a few minutes.
3. Reinsert the battery.
4. Charge the device to 100% without turning it on.
5. Remove the battery again and put it back after a while.

This procedure must be repeated 2-3 times, which will help restore the vitality of your battery and “teach” it to correctly calculate its capabilities.

If none of the above has returned the Android phone's ability to charge, there is only one thing left to do - take it to a service center, where specialists can detect and fix problems.

To avoid such problems as much as possible and extend the life of your battery and charger, you need to follow simple tips:

• As soon as you notice that the gadget is charging slower or slower, calibrate the battery. In addition, it is recommended to do this for preventive purposes once every few months.
• Try to charge your smartphone (or tablet) from a power outlet rather than from a computer - this way charging will be more efficient.
• Do not overexpose or leave the device connected to the charger overnight, as this may cause overheating and damage to the battery.
• Do not charge the device in an extremely humid or hot environment (for example, in a bathroom or in direct sunlight).

Are you trying to find the problem that is associated with the phone charging error, but nothing works? We recommend that you familiarize yourself with the likely problems that often affect new smartphones.

The phone takes a long time to charge: why does this happen?

Charging problems with smartphones are common. If you are faced with a situation where the phone only gained a couple of tens of percent during the entire night of charging, most likely the battery has failed. Usually this happens suddenly, without preliminary symptoms.

In emergency situations, if there is a problem with charging, you can cut off the cord plug and connect the contacts directly to the battery. Experts from our editorial team argue that such a procedure is often impossible, as it reduces the service life of the battery.

Why did my phone stop charging?

A complete lack of charge in the phone may be the cause of a malfunction of the smartphone output or its clogging. Often it is enough to blow the phone connector with cold air to restore charging ability.

The adapter may have an invisible (internal) defect, in which case it is necessary to ring the bends.

A broken wire can also cause a lack of charge. You can try moving the cord in different places to see the electrical signal going to the battery. If the smartphone does not receive energy when turned on, but charges normally when turned off, there may be a problem with the chip. Fixing such a problem can be quite expensive, and the cost of repair also depends on the smartphone model. For more details about the causes and methods of diagnosing them, see our next sections.

How to diagnose if your smartphone does not charge

When it is absolutely necessary to use the phone, the user must try in every possible way to check the device for functionality. At home, you can detect a malfunction of the connector, adapter, or software dysfunction.

If the battery fails, the smartphone may charge, but not fully.

Some reasons can be easily fixed with your own hands - for example, replacing the battery or connecting another charger.

A way to check the connectors on your phone if it won’t charge

It is necessary to carry out an inspection of the charging cords and phone connector first. According to statistics, malfunctions with these components most often occur in smartphones. All the user needs to do to test is to connect another adapter to the socket. If no changes are observed and there is no nutrition logo, the problem is in the internal mechanism. Try to solve this problem by cleaning the contacts: take a cotton swab, lightly moisten it in alcohol and go over all accessible places. If the socket is too narrow, take a thin paint brush (a makeup brush will do) and clean off any accumulated dust.

Mobile phone battery diagnostics

Lack of charge is a fixable matter if the fault is only in the battery. It is enough to simply replace it with a new one, and the smartphone will be ready for use. However, you should first confirm that it is the battery that is the problem.

First of all, visually inspect the battery: if it is swollen, then it is on its way to disposal. If there are no signs of deformation of the battery case, you need to check its ability to receive and hold power. This can be done using a special tester (radio technicians usually have one). You need to call your contacts back.

If you do not have any skills in this area, you can try a simpler method of determination. It’s worth noting right away that it is risky, as it carries the risk of injury from accumulated voltage. Take the battery and place your tongue on its contacts - if you feel a tingling sensation, the battery is working.

If the phone refuses to charge through the connector, but you need to receive or make a call in the near future, you can charge the battery separately using a frog charger.

universal frog charger

The USB cable is considered the weakest link in a smartphone device.

Scanning with an antivirus program

A virus is a potentially dangerous program that can harm not only the phone’s software, but also cause problems with the hardware. One of these problems is the lack of charge. Associated signs of infection with the virus are:

• “sluggishness” of the smartphone;
• unreasonable “kickout” from games or applications;
• Players freeze;
• lack of indication for various connections made using the phone;
• advertising pops up on the screen even when there is no Internet connection.

The user can only check the smartphone for viruses with a special program. If this cannot be done using the built-in utility, connect the gadget to the PC via USB. If an infected component is detected, the protection program will automatically remove the virus.

If the problem cannot be solved, you need to contact a service for professional cleaning of the cellular operating system.

How to use USB to check charging functionality

When a comprehensive diagnosis of a smartphone begins, it is imperative to check the power supply via a USB cable. To understand whether the problem is with the adapter, you need to connect one end of the cord to the smartphone and the other to the output on the PC. If a signal appears on the monitor about a new device connection, the cable is working. If the charge does not come from the computer with a working cable, the problem is most likely in the internal board of the mobile phone.

What to do if your phone is charging very slowly or not at all

Charging problems are not always related to the battery itself being exhausted. There are plenty of problems that manifest themselves with such signs, so it is important to first make a diagnosis, and then think about what to do next. In this section, we will look at some possible solutions that, if they do not resuscitate your smartphone, can at least suggest some further actions.

When the power cord or adapter is damaged

First of all, try buying a new charger of the appropriate model. However, many people practice quite successful independent repairs. It is necessary to purchase a new charger when the battery is normally charged from another suitable adapter.

Try cleaning the charging connector contacts. An ordinary match or toothpick is suitable for this.

Try charging your smartphones directly until you solve the problem with the natural way of power supply.

Software failure as a cause of charging failure

Failed smartphone firmware or downloading of certain applications may result in incorrect charging display. Perhaps there are junk files in the operating system's memory that urgently need to be cleaned out. To do this, you can use applications such as Clean Master or Cleaner.

If this does not help, at home you can roll back all changes by restoring to factory settings or completely reboot the device by pressing the Reset button. It is a small hole on the smartphone body with the diameter of a regular sewing needle.

What to do if your Android phone won't charge

Android gadgets require power every two to three days. This usually happens not so much due to intensive use, but rather due to the low capacity of the batteries. One day the user may experience a lack of charge. If you have analyzed all of the above reasons and have not found a problem, it is most likely caused by software instability.

What to do if your Windows smartphone does not charge

If a smartphone running Windows OS does not charge, then you can immediately suspect a software failure, since the chargers and the phone case connectors themselves are very durable. The first thing we can do is reset the system to factory settings. You can find the cleaning tool in the settings of your smartphone.

Also, the problem of lack of charge can occur when updating your phone data. In this case, you can roll back the changes to a previous working version. Please note that this procedure can only be performed when the parameters provide for data backup.

Oxidation of the inside of the connection socket

The first symptom of oxidation of the charging connector is loss of power if the smartphone is directly charged. You can fix the problem with the nest using soda and a thin needle. To get into the compartment and thoroughly clean everything, you need to wrap a thin layer of cotton swab around the needle (so that it still fits into the connector), then lightly moisten the top and dip it in soda. Insert the needle inside and carefully remove the plaque.

The disadvantage of this method is that sooner or later oxidation will appear again. If you want to get rid of oxide forever, you need to order a new connector and replace it.

Loss of battery starting impulse

Complete battery depletion can occur for various reasons. However, there is a high chance of the battery being restored. First, you need to connect a completely discharged smartphone to the adapter for a day. Do not rush to panic if there is no reaction on the screen. Sooner or later, the phone will “seize” the impulse and begin to accumulate battery capacity.

A charging error may indicate an uneven insertion of the charging plug.

The following method of resuscitating batteries is suitable for any type of smartphone, but does not always work. Try removing the battery from the cell phone case, then connecting the charger to an empty smartphone, and then inserting the battery into its place. Leave your smartphone turned off for half a day.

Controller malfunction

The smartphone board contains mechanisms that are responsible for the operation and adaptability of the battery to charge. During sudden voltage surges, a problem may arise with the controller, which begins to ignore the charge; accordingly, the received power does not reach the battery and is not displayed on the phone screen.

Repairing such a problem is quite expensive. Sometimes the cost of this operation can be close to the price of the smartphone itself. In this case, it is more profitable to buy a new gadget. If repair is not possible, purchase a Power Bank for the kit and connect your phone to it via Micro-USB.

The phone shows charge, but does not charge after being dropped

If the smartphone suffered a hard fall and from that moment stopped charging, and when connected to the power adapter the charging indicator lights up, this indicates that after the impact the battery was deformed, or the contacts of the battery or the socket itself to which the container is connected came loose. Check all these points; in the worst case, you will have to purchase a new battery.

Why phones of different brands do not charge well: how to fix the defect

Each brand of smartphone has its own nuances that can affect the performance of the batteries.

Apple phone won't accept charge

For example, Apple phones are often sold with non-original charging adapters, because real ones are quite expensive. Due to unscrupulously manufactured products, nutritional problems occur. Chinese iPhones can work for about two years without a hint of malfunction, but at one point they simply refuse to charge. This is due to damage to the chip, which is responsible for many of the device’s functions. You can try charging such a device in the off state for some time.

The following principle will help you determine exactly what the problem is when the chip is not working: when the smartphone is turned off, it charges in the usual mode, but when it’s working, power can accumulate for two to three days.

What to do if your Samsung phone won't charge?

Most Samsung smartphones run on the Android operating system, so if the charging problem is not due to mechanical damage, then only the existing software could have an effect.

In this situation, we will try to calibrate the battery. First of all, you need to obtain Root rights. This can be done using a special pre-installed utility. Then download the Battery Calibration program from the Play Market service and run it with permission to make changes to files.

Now you can connect the charger and wait until the battery reaches 100% charge. Then calibrate, then re-discharge and charge the smartphone. As a result of such actions, the old file about the battery status will be deleted, and the new one will be saved in the settings.

Each smartphone has individual structural features of its internal circuits, so each problem may have some internal differences from, at first glance, an absolutely similar one. Write in the comments what brand your phone is, and we will tell you in a reply message how you can revive it.
