Why won't my phone charge from the charger? If the device shows charging but is not charging

If the phone stops charging, then this is an extremely unpleasant problem. Most often, owners of old, almost used-up batteries encounter this problem - their service life is 3-5 years, and with modern load on mobile device It may not even reach two. However, the reason is not always the old battery; there are others.

Which phones are affected by the problem?

A modern smartphone is a complex communication device, and not just a telephone. With it, you can surf the Internet, listen to music, play games, watch videos, take photos, and so on. Therefore, the load on it is much greater than on a device designed only for making calls and sending SMS.

In addition, at modern models There is no connector dedicated specifically for charging. As a result, charging is carried out through a single connector, which is integrated with USB, and this process is closely linked to the software.

Therefore, charging problems are the most common failure among mobile devices. And no one is safe from them, not the owners expensive smartphones, nor cheap Chinese ones. Although it is believed that the latter are still more vulnerable and less reliable.

Main reasons and their solution

Reasons why your phone won't charge charger, several, and they manifest themselves in different ways. Most often the problem is in the memory itself. If it is faulty, the smartphone will not respond in any way to connecting to the network. It’s easy to check: you need to find a 100% working charger suitable model and try connecting your mobile phone to it. If the process continues, then it’s time to change the memory. But there are also more complex situations. For example, when the phone does not turn on or shows that it is charging, but in reality the opposite happens.

Important! The reason your phone won't charge could be... a faulty socket! It's trivial, but before you panic, it's worth checking this too.

Phone shows charging but won't charge

Many smartphone owners have encountered this problem: when connected to the mains, the corresponding indicator lights up and a filling battery appears on the display, but in fact the charge level does not increase or, worse, charges at reverse side- that is, it is discharged.

There may be several reasons for this:

1. Not the original memory. Modern mobile devices may not charge from non-original chargers, that is, they see the connection, but do not allow electricity into themselves, since the voltage is supplied above or below the recommended one. iPhones are especially famous for this.
2. Weak memory. If the charging power is noticeably less than required for a given battery model or the process is carried out via USB from a computer, then the device will take a very long time to charge, and if at the same time you play on your smartphone, watch videos or sit on social media. network, then the phone will simply discharge faster than charge.
3. Memory fault. The cable, adapter or connector may be damaged. There may be a tear or bend in the cable, oxidation of the contacts or a failure in the board of the adapter itself.
4. Battery failure. The battery has outlived its usefulness and all that remains is to replace it.
5. Calibration failure. The smartphone may not correctly see the battery capacity; for this it needs to be calibrated. Discharge and charge several times.
6. Background applications. If you do not use your smartphone while charging, but it still does not charge, then the processor may be spinning large number running applications V background. It is worth turning off wi-fi, mobile internet and GPS. Close all applications, check your phone for viruses with an antivirus.

Phone won't turn on or charge

If the mobile device stops turning on and charging, this may be evidence of a serious breakdown, which can only be diagnosed and repaired by a service center.

1. Problems with the memory. Perhaps the smartphone does not turn on because it is completely discharged and the memory has become unusable. You can check this by connecting the device to another suitable charger.
2. Deep discharge. If the phone is discharged to 0 and does not charge, then perhaps the battery has gone into a deep discharge and the controller no longer passes current; in order to revive it, you will have to use a universal charger.
3. Phone or battery failure. If the battery is removable, then you can temporarily ask someone you know for the same battery to find out who has the problem. As a last resort, you can try to turn on the phone from the wires.
4. Firmware glitch. This can happen when failed update Software, virus infection or glitch. You'll have to take it to the SC.

Phone charges but won't turn on

If, after connecting to the charger, the indicator on the smartphone lights up, but it does not turn on, then the following could happen:

1. Didn't have time to recharge. If the smartphone is very discharged, then you need to let it sit on the charger for a while, from 5 to 30 minutes. After which it should turn on.
2. Firmware. You need to hold down the hot keys on your smartphone to reset the settings to factory settings. (You can view them on the Internet, since each model has its own). If it doesn’t help, then we take it to the SC.
3. Hypothermia. If exposed to sub-zero temperatures for a long time, the device may turn off and not turn on. You shouldn’t put it on charge right away; it’s better to wait until it warms up to room temperature, and then connect it to the network.
4. Battery problems. If the battery has become unusable, it may indicate that the charge is coming, but in fact there is no more capacity left in it and there is simply not enough power to run the smartphone.

The phone does not charge in the car using the cigarette lighter

When connecting a mobile device to the cigarette lighter, you need to know that the current here will be weaker than from electrical outlet, so the phone will take longer to charge. If you are using a navigator or running other applications at this time, the phone will not charge, and may even begin to discharge.

Another reason is simple contamination of the cigarette lighter socket. If so, then you should clean it. The socket may also be faulty. You can check it by connecting another device. Another possible reason is a “non-native” wire.

New phone or battery won't charge

1. Factory defect. If you bought a new battery or phone in a store and it does not charge, then the most probable cause- This is a factory defect. The memory may also be defective. There is no need to try to fix the device yourself; it is better to return to the store and exchange it for another one.

Important! Be sure to check the functionality of the phone, battery and charger in the store, then you won’t have to go twice. When shopping in an online store, you need to be aware that returning will be more difficult.

1. Taped contacts. On a new battery, the contacts are sealed with adhesive tape to protect them from oxidation. If it is not removed before inserting the battery into the phone, it will block the flow of current. Therefore, before this, the battery must be inspected from all sides and unnecessary protection removed.
2. Deep discharge. If the device or battery was stored in improper conditions, then the battery could go into a deep discharge; we go to the store to exchange it for a new one. If it dies after short-term use and this is no longer a warranty case, then you can try pushing the battery.
3. Hypothermia. If everything was in order at the store, but when you got home the battery refused to charge, then this could have happened due to frost. You need to give the device time to warm up to room temperature, and then put it on charge again.
4. Incompatible battery. New battery may not charge because it is not compatible with your phone. You need to be more careful when choosing.
5. Oxidation of phone contacts. A new battery in an old phone may not charge due to oxidation of the contacts between the battery and the smartphone. If this is the problem, then maybe the old battery is good.

Important! If you have new phone or battery, you should not repair it, as you may lose your warranty. Within 14 days of purchase, the store must replace the device without question, then the warranty will be from 1 to 2 years, depending on the manufacturer.

Have you ever had a case where your smartphone stopped charging from the charger? Tell us in the comments what the reason was and how you managed to solve it this problem. This will help make the material more complete and useful.

The battery capacity of most Android smartphones and tablets allows you to actively use the device without recharging for 12–24 hours. The charging time of the device is two to three hours. But sometimes the gadget suddenly drops its charge level, quickly discharges, loses battery charge when connected to an outlet, or completely stops responding to the charger being connected. If your smartphone has stopped charging, check possible reasons and solutions to this situation.

What to do if your Android phone or tablet is not charging. Possible reasons

Common reasons for lack of charging are a breakdown of the power supply or Micro connector USB, battery wear, software glitches. When you realize that your smartphone or tablet is not charging, first check the voltage at the contacts of the battery and charger. If everything is fine, use other methods to restore your smartphone or tablet.

Shows that charging is in progress, but is not charging from the mains

If, when connected to an outlet, the indicator shows the charging process, and when you disconnect the cable, the smartphone or tablet turns off, the charge level controllers are probably shorted. A short circuit occurs as a result of water getting inside the case or a broken connector.

Try testing the device with a different cable and battery - if the result is the same, take your smartphone or tablet to service center. Specialists will detect and replace the faulty element.

The charging percentage does not change via USB from the computer

Users often charge smartphones and tablets from a laptop rather than from a wall outlet. Reasons why a smartphone, with a working battery, does not receive power from the computer:

• broken or insufficient cable thickness;
• insufficient current for charging;
• the connection is blocked by the PC operating system;
• The “USB charging” function is disabled in the device menu.

If you find a break in the wire, connect the two broken ends together and rewind with electrical tape. If the current supplied to the USB port is not sufficient to charge, try connecting the device to a different port.

The Ubuntu operating system blocks charging more often than others. To bypass the blocking, blacklist your smartphone at /etc/default/tpl.

Completely discharged and won't charge

Smartphones and tablets do not respond to connecting a charger when the battery is deeply discharged. If the gadget was discharged more than a day ago and shows no signs of life, plug it into an outlet and leave it turned off. After 10 minutes, check if the charge indicator lights up. If yes, you can turn on the device.

If the indicator does not light up, clean the Micro contacts USB connector and the plug on the charger cable. Take a thick needle and use the opposite end to remove small dust particles and pellets. Insert the plug into the connector and leave the smartphone or tablet for another 10 minutes.

A common situation when users suspect charging problems is a broken display. At the same time, the gadget is charging, but you don’t see it - the screen remains dark. To check whether charging is in progress or not, use the light indicator on the case. If there is no indicator, turn on the device. If the display breaks down, you will hear a characteristic system startup sound, and if the charging connector does not work, the gadget simply will not turn on.

Stopped charging from the cigarette lighter

When charging your smartphone in a car, you may encounter the problem of a lack of charging from the cigarette lighter. First, try connecting another device and check the fuse box in the car. Perhaps the one responsible for supplying current to the cigarette lighter socket has burned out. If the fuse is OK, disassemble the charger plug and check the condition of the fuse.

If the battery indicator is displayed on the screen, but the charge level does not increase and even decreases, it means that the cigarette lighter is supplied with a low current that is insufficient to power the smartphone or tablet.

The device blinks but does not charge

Smartphones and tablets equipped with a color indicator blink while charging. If your charging indicator blinks unusually (for example, it was always blue, but is now blinking green and red alternately), and the device is discharged, the problem may be that the processor is overheating. In this case, restart your tablet or smartphone in Recovery mode and try charging. If the situation does not return to normal, clean the connector and plug contacts and reconnect the cable. Continued flashing means it is time to replace the battery with a new one.

Problems charging a smartphone or tablet

Problems modern gadgets are associated not only with the lack of charging when the cable is connected. It happens that a tablet or smartphone is charging, but then the charge level drops sharply, or the device turns off when the battery level is 90% and stops turning on. The recommendations below will help you cope with the problem.

Charges only when turned off

After a fall or software failure, the smartphone can only accept charging when it is turned off. Options to solve the problem:

• reset settings to factory settings;
• reflashing the device.

If software methods don't help, maybe it's damaged Micro USB connector, and assistance from service center specialists is required.

Charging, but not fully charged

If the power indicator is displayed, but the smartphone does not show a 100% charge level, battery calibration is necessary. The second reason is insufficient current for a full charge. Check the charger for cable integrity and, if necessary, change to a two-amp model with a thicker cord.

If the suggested methods do not help, replace the battery with a new one.

Doesn't charge more than 1%

In a situation where the charge percentage does not rise above 1%, check chargers with other gadgets and try charging your smartphone or tablet from a computer. If that doesn't help, replace the battery with a new one.

Doesn't charge until rebooted

Incorrect charging of gadgets is often associated with software. If your smartphone does not charge without restarting or restarts while charging, follow these steps:

• remove unnecessary programs from the system that may affect the charging process;
• roll back to standard settings;
• connect another cable;
• reflash the device.

The device discharges when turned off

It is normal for a working battery to gradually decrease its charge level even when the smartphone or tablet is turned off - by about 1% per week. But if you turned off the device at night with a 100% charge level, and turned it on in the morning and saw a reading of 50%, most likely the battery needs to be replaced. If the replacement does not produce results, the problem is in the processor - take the device to a service center.

The device is charging but shows an incorrect charge value

When the charge indicator displays an incorrect value - for example, it shows 50%, and after a minute it turns off and displays 0–5% the next time it is turned on, calibrating the battery helps. To calibrate the battery:

1. Discharge your smartphone or tablet. When it turns off, turn it back on and wait until it turns off. Do this until the device begins to turn off after a second of active mode.
2. Remove the battery for five minutes and install it back.
3. Connect the charging cable to the gadget. Charge it without turning it on.
4. Remove the battery again for 5 minutes without turning on the device.
5. Install the battery and turn on the smartphone/tablet.

If manual calibration does not help, try downloading a calibrator app.

Why does my Android phone or tablet run out quickly?

Android gadgets maintain their charge level throughout the day. If the device discharges faster and you need to extend the operating time of the device, use the recommendations below.

What processes contribute to battery discharge?

The charge level is affected by the brightness of the screen and communication modules. You can optimize battery consumption by making a number of settings. Go to your device settings and disable the following features:

• 4G connection - 4G networks do not work in all regions, and when the option is connected, the smartphone is in constant search networks;
• bluetooth - connect only to transfer files;
• wi-fi - increases charge consumption by 15%;
• GPS - required only for navigation and location determination;
• auto-rotate display - the function uses the accelerometer and gyroscope, consuming energy;
• vibration response to touch.

Close applications running in the background. If you are using a launcher and themes, disable them. Also disable automatic synchronization and application updates.

The device charges quickly and discharges quickly

If your smartphone discharges quickly and charges just as quickly, the problem lies in the battery. Try charging your phone to 100%, then discharging it until it turns off, and so on several times. If the battery does not charge better, replace it with a new one.

The device takes a long time to charge and discharges quickly

The charging time for a smartphone or tablet depends on the power source. It is not recommended to use universal cables to power the device - the current may not be sufficient and charging will occur slowly.

If you are using an original charger, but the battery level is growing slowly, try charging the device while it is turned off. If 2-3 hours after turning off the phone the charge indicator shows 100%, look for problems with software. If charging a switched-off gadget takes longer, the problem is in the hardware.

Charging a cold battery is slower, so do not connect the cable to the phone immediately after returning from the cold. Wait until the device warms up to room temperature.

The gadget quickly discharges in standby mode

In standby mode, the accelerometer and gyroscope consume the battery. They are designed to control the movement of the device relative to the ground and the human body. To make the level drop more slowly, turn off the sensors. Also close background applications. To do this, go to the “Settings” menu, select “Applications” and on the “Running” tab, stop unnecessary ones.

If actions with the software do not help, there may be damage to the motherboard. In this case, the smartphone or tablet requires repair.

Battery charge drops sharply

Changes in charge level values ​​do not give the user the opportunity to determine how long a smartphone or tablet will last without recharging. If you're concerned about battery level fluctuations, try calibrating your battery manually or using the Battery Calibrator app.

When calibration does not help, connect a light bulb directly to the battery contacts and wait until it stops shining. Then install the battery in the smartphone and charge it to 100%. After repeating the procedure three times, the charge level will be displayed more evenly.

The charge began to drain quickly after the update

Software updates require more energy from smartphones and tablets, which means they drain their charge faster. If after the update your gadget begins to discharge faster, reset the settings to factory settings, first saving important information.

Another common reason is a virus that got into the phone with the update. Find virus program and delete it. To do this, use an antivirus - Kaspersky, McAfee or Dr. Web.

How to check the battery status

There are various ways checking the battery condition.

During charging, you may see a question mark on the battery icon - it appears when the battery is worn out, indicating the need for replacement, or in cases where the plug contact comes off.

How to charge an Android device with a broken connector

Charging problems are often associated with a broken Micro USB connector. If it fails and you need to extend the operating time of your gadget, use a wireless charger. Attach the receiver to the battery and turn it on. In an hour the battery will be charged.

In extreme cases, the battery can be charged directly from the power cable. To do this, just cut off the plug, connect the wires to the contacts and plug the power supply into the outlet. Do not use this method if you are not confident in your knowledge of electrical engineering, and if you use it, constantly monitor the charging process.

How to properly charge Android devices

To extend the life of your battery, charge it properly. The charging method depends on the material from which the battery is made. Lithium-ion batteries charge to 100% and discharge completely, and recharge lithium-polymer as needed. Other rules for charging smartphones and tablets:

• Do not leave a charged gadget connected to the cable. Once the battery is 100% saturated, turn off the power.
• Use original power supplies from the manufacturers.
• Do not charge the device after returning from the cold.

Users usually experience charging problems a year or two after purchasing a smartphone or tablet. If you notice a problem since purchasing the device, before repairing it yourself, contact a service center where the gadget will be repaired or replaced under warranty.

Battery charging problems are one of the most common problems with tablet computers. It is especially common on unnamed products by Chinese craftsmen: one could even argue that it is typical for tablets costing $30-50. Branded models of popular brands in Russia - Asus, Lenovo, Samsung, etc., do not suffer from this so often, but sometimes you have to tinker with them.

The majority of charging faults are related to the hardware of devices, but some are caused by software glitches and are quite easy to eliminate. Let's talk about the reasons for charging "glitches" of tablets and how to "revive" your iron friend on your own, whenever possible.

Battery wear

Lithium-ion and lithium-polymer batteries used in tablet computers last less than the device itself: approximately 2-4 years. But their performance depends more strongly not on the duration, but on the operating conditions: the number of charge cycles (battery life) is inversely proportional to the depth of charge-discharge: the greater the latter, the faster wear occurs.

As the battery ages, it loses capacity. When it becomes very low, the tablet discharges from 100% to 0% in less than an hour. In addition, a battery that has reached the end of its life is characterized by an incorrect indication: the system shows a higher or low level charge than it actually is.

To solve this problem, as you may have guessed, just replace the battery with a new one. To do this, you will need skills in disassembling your gadget and soldering (in tablets, batteries are most often soldered).

When choosing a new battery, you should look at the following:

• Voltage: 3.7 (3.8 V) or 7.4 V. This indicator should exactly match yours.
• Dimensions: length, width and thickness do not have to be the same as the old one, but new battery should fit freely into the housing. You can't squeeze it.
• Capacity (in milliamp-hours). Preferably not lower than it was.
• Number of contacts: there can be 2 (positive and negative) or 3 (plus, minus and temperature sensor output). If the old battery had 2 contacts, any one will do (you don’t have to solder the third wire), if there are 3, it is advisable to take the same one.
• Novelty. A “not fresh” battery most likely does not correspond to the declared capacity, since the latter decreases during long-term storage.

Owners of branded devices such as Samsung Galaxy Tab 3 or iPad, the choice is easier - they should look for a battery specifically for their model.

Faulty charger (charger)

Chargers inexpensive tablets fail quite often. And sometimes they initially do not correspond to the nominal characteristics. Such a charger can “cunningly pretend” to be working, but the current it produces is so small that the gadget does not have enough of it (the average tablet computer consumes about 2 A).

When connected to a “half-dead” charger, the following picture is possible:

• The tablet shows charging, but is not charging.
• The tablet takes several times longer to charge than usual.
• The charge level does not increase, but decreases, despite the fact that the indicator shows the charging process.

To check this version, connect the device to a known-good charger or external battery, the voltage and current of which correspond to the rating of your charger. If the problem is resolved, the charger should be replaced.

By the way, the computer’s USB port is not suitable for testing, since it produces only 0.5 A (USB 2.0) or 0.9 A (USB 3.0) instead of the required two.

Malfunction of the charging and/or power supply system of the tablet

Problems internal system nutrition is one of common reasons, according to which the tablet made in China does not charge. Explanation - low quality element base and assemblies.

Devices from well-known manufacturers “get sick” with such a disease more often due to the fault of the users. For example, due to the connection of cheap, low-quality chargers (especially car chargers), careless handling (falls, impacts), or liquid getting inside.

Externally, the malfunction manifests itself in a variety of ways:

• The tablet shows charging constantly, including when it is not connected to a charger. And vice versa: does not detect the power source when it is connected.
• Charging is no longer detected from time to time.
• The battery drains quickly even after turning off the gadget.
• The tablet does not turn on, turns off on its own, or freezes (until rebooted).
• The charge indicator shows incorrect numbers.
• The tablet becomes very hot while charging.

Attention! Excessive heat during charging may indicate battery damage. You cannot operate or charge such a device: faulty lithium batteries tend to ignite and even explode!

The culprit of the problem may be the connector, the power controller chip (it also controls charging), its wiring elements, or the battery. At home, without knowledge of electrical engineering and diagnostic tools, the problem cannot be solved, so it is best to take the gadget to specialists.

Software failure, viruses

The reason that the tablet takes too long to charge and discharges quickly may be trivial viruses. Some of them, unnoticed by the owner, use the computing resources of the processor, Wi-Fi, cellular communication, turn on the camera and microphone. This requires additional energy.

We recently told you... The advice given in that article is also relevant for other devices: if you suspect an infection, immediately scan the system and removable media good antivirus.

Software failures of other origins (not related to viruses) may manifest themselves as the following symptoms:

• Incorrect charge indication.
• Discharge too fast.
• Incomplete charge (when a certain indicator is reached - less than 100%, the charge level stops increasing).
• The device “thinks” it is charging when the charger is not even connected to it.

To resolve this problem, try the following (one thing doesn’t help, go to the second, etc.):

• Remove applications that you installed before the crash.
• Carry out 2-3 full discharge cycles (before turning off) and then charging the battery for 6-8 hours.
• Reset operating system to factory settings.

Battery over-discharge

Tablet batteries operate in a narrow voltage range: from 4.1-4.3 V to 2.7-3.3 V. A higher value corresponds to 100% charge, a lower one - 0%. When the voltage drops below the threshold level, the protective controller (a small card connected to the battery cells) disconnects the battery from current consumers (tablet devices) in order to prevent further discharge and failure. But at the same time, the battery is also disconnected from the charging circuit, that is, it loses the ability not only to discharge, but also to replenish electricity reserves.

When the charge level drops to 10-15%, the tablet should, in theory, turn off, but sometimes this does not happen. As a result, overdischarge occurs, and the gadget stops responding to connecting a charger to it.

In order for the battery to regain the ability to charge, its cell voltage must increase to 2.7-3.3 V. This can be achieved in two ways: slow and fast.

• The “slow” method is very simple: connect the charger to the tablet, turn it on and leave it for several hours. Safety controllers lithium batteries capable of detecting a connected charger and allowing charging when voltage appears at the terminals.
• The quick method or, as it is called, “push” the battery is recommended only experienced users. Recover with it normal function Charging can be done in 10-30 minutes, but this requires some knowledge of electrical engineering and the ability to disassemble your tablet. Let's look at it in more detail.

How to “push” a dead lithium battery

To do this you will need:

• Voltmeter.
• Soldering iron (optional).

Operating procedure:

• Cut off the connector from the charger and strip the ends of the wires by 3-5 mm. Use a voltmeter to determine the positive and negative wires. The first one is usually red, the second one is black.
• Connect a resistor to the positive wire (you can simply screw it on, but it’s better to solder it).
• Disassemble the tablet. Connect the negative wire of the charger (solder or glue with tape) to the battery terminal marked with a (-) sign, the other end of the resistor to the terminal with a (+) sign.

• Plug the charger into a power outlet.
• After the voltage at the battery terminals rises to 3.3 V, remove the structure and connect the tablet to the power source through the connector. It will now charge as usual.

Attention! During the “pushing” process, be sure to control the temperature of the battery with your hand. If it starts to get noticeably hot, immediately disconnect it from the power source.

Imagine the situation - you discover that your phone's battery is dead. You take the charger, connect it to the mains, connect the handset, but there is no response. Why won't my phone charge from the charger? There can be many reasons, and many of them can be eliminated at home, without special tools or knowledge. Let's find out what you can do if there is no battery charge.

Phone stopped charging

Phone battery not charging? The reason may lie on the surface - this is a broken charger. So we need to test it. To do this, use other phones or digital gadgets with a suitable connector. We connect the charger to the selected device and look at its reaction.

If the battery does not charge, this indicates a faulty charger. Repair shops don't repair them - it's easier to buy a new one. If your connected device starts charging, this may indicate a problem with your phone.

There is no point in disassembling it, since you will not be able to find the fault without diagnostic equipment. Therefore, we recommend checking the socket to which the charger plug is connected - it can be cleaned with a piece of paper folded several times, thin cardboard or a toothpick.

After this, we check the charging capability again. Didn't that help either? Then you can try charging your phone with a different charger. Sometimes, for reasons that are not very clear or explainable, this works. Find another charger in your house and try connecting it to your phone. If the battery charge begins to replenish, continue charging.

The phone does not charge from the charger under any conditions? Take it to the nearest service center or a private repair shop - it is quite possible that something has happened to the built-in charging circuit (damage to the electronic part of the device). This may also be due to a broken socket or microcracks on the system board phone or smartphone.

Phone shows charging but won't charge

Charging is in progress, but the phone is not charging? It is possible that the problem is related to a faulty charger. By all indications, it works, but the current it produces is simply not enough for full charging. As a result, the charge indication is present, but the current strength is not enough to fully fill the battery.

Under such conditions, the duration fully charged battery may be too large. If the current consumption is greater than the charging current, the battery will soon be discharged to zero and the phone will turn off.

Sometimes this problem occurs as a result of electronic failure - it incorrectly calculates the remaining battery capacity, preventing it from charging normally. It is impossible to do anything about this at home, even if you replace the charger with a more powerful one. All that remains is to contact the service center for help.

Phone doesn't charge well

The phone does not charge from the charger - what should I do? There are several checks you need to perform:

• Test the current charger on another gadget;
• Test another charger on your phone;
• Try more powerful charging(for example, from a tablet);
• Clean and check the connector.

If the phone battery does not charge even after this, feel free to go to the service center. But what to do if the phone charges, but poorly? We have already said that for this you need to check the charge current and check the phone itself. But we forgot the most important thing - The reason for the lack of normal charging may be a loss of battery capacity.

In this case, the charging process extends for several hours, and after disconnecting from the power supply, the phone discharges literally before our eyes. If so, try replacing the battery - this helps in most cases.

Is your smartphone not charging? Then you need to try removing third party application, responsible for saving the battery (if it is available). The thing is that some of them come into conflict with the hardware, making normal battery charging impossible.

It often happens that the phone does not charge, and this problem occurs on both old and new phones.

There are also situations when charging in progress, but very bad, slowly, up to a day.

Why such problems arise and what to do to solve them will be discussed further.

Problem #1. Broken cable

Often, USB cables burn out, break at bends, or simply stop transmitting a signal.

Therefore, the first thing to do if the battery does not charge is simply check the charger cable.

If, for example, a defect is found on it, which is shown in Figure No. 1, you can try to manually press one end to the other or wrap the break with electrical tape.

You can also try taking a toothpick or a regular match and literally picking at the inside of the USB tip in those places shown in Figure 2 with arrows.

You can take a regular painting brush for this and walk it along the inner surface of the tip.

It is quite possible that the reason is that there is dust or some kind of debris inside.

No. 2. USB cable tip

To rule out this option, you need to try charging using a different charging cable. You may have to buy new charger.

If the problem does not go away, then the problem does not depend on charging.

Problem #2. Phone connector

There is only one way to eliminate this option - charge the battery outside the phone itself.

For this there are special individual devices for charging batteries. An example of this is shown in Figure 4.

The same can be done using another phone that uses the same one. You can also use a homemade charger. It's very easy to make.

This could be two simple wires connected to the battery terminal (shown by the red arrow in Figure No. 5). You can attach them even with the most ordinary electrical tape.

The video at the end of the article explains this method in more detail.

Problem #3. Bad battery

Batteries tends to break down after long use. Therefore, you can install another battery and try to charge the phone again.

You can simply remove the battery and put it back in. There are times when this helps too.

Important! When you open the phone, feel the battery - it is quite possible that there are some irregularities, bulges or other deformations on it. This means that there is no point in trying to restore the battery - corrosion begins to do its job.

Then you definitely need to buy a new one, because otherwise other metal parts will begin to corrode.

If the phone is without any curved decorative elements on the body, you can simply put it on the table and unwind it.

If it spins, it means the battery is swollen and this will cause back cover some bulges appeared.

A swollen battery looks as shown in Figure 6. Of course, it may not reach such a critical state, but if the swelling process has already begun, then it will not end.
