The phone does not charge through the computer. Why your phone won't charge - reasons and solutions

Useful tips

Over the past 20 years, phones have become an integral part of our lives. Not every home may have a TV, but every family member has a smartphone. Even little first graders usually have a means of communication for emergency calls. The gadget performs various functions: from the ability to call to music player and readers. Therefore, a person whose phone stops charging finds himself in a state of mild panic. We have collected various reasons why your phone won't charge and ways to solve these problems yourself.

It sounds very stupid, but sometimes it is this side that really lets you down. And it will be very disappointing, after disassembling the phone and trying all the options, to suddenly realize that the problem was with the socket. Therefore, first of all, try moving the charger to a different outlet.

Faulty wire

Very often the problem lies in the charger itself. They are not as durable as we would like, and constant use of the cord greatly shortens its life. This usually doesn't happen suddenly. First, you start to notice that the phone only charges in a certain position. You begin to twist the charger, fix it in a bent state to get the desired charge. But at some point the cord stops working completely.

First of all, check that your power cord is working properly. If your phone is standard android, then finding the cord is not a problem. You can go to any communication store and ask to check the gadget. Usually such requests are not refused, because you will buy a new cord in the same store.

Attention: if your mobile phone is one of those models where there is access to the battery, then it is tempting to connect the wires directly to the battery. In an emergency, this method will work. Simply cut off the adapter, strip the wires, and connect them to the battery contact. But such experiments damage the battery itself; it stops holding a charge. Then you will have to buy not only a charger, but also a new battery. Therefore, do not resort to this method.

Clogged contacts

The problem may be contamination or oxidation of the contacts. To solve the oxidation problem you will need alcohol and a thin brush. Lightly wet the brush with alcohol and carefully clean the connector. It is more convenient to remove dirt and dust from the connector using a thin needle or toothpick. Just be very careful not to damage the connector.

Power adapter failure

If your phone won't charge when plugged in, try checking the power adapter (the small box that plugs into an outlet). If it is too hot or, conversely, cold, this may be an indirect sign of a breakdown. Connect your phone to your computer via a USB cable. If it starts charging, the problem is with the adapter. Go to any hardware store and buy a new one that matches the model of your device.

Faulty charging connector

It happens that the phone shows that it is charging, but the charge still “melts before our eyes.” Even if you connected it to the network or power bank.

If everything is absolutely fine with the cord, the reason may lie in a faulty connector. This problem also manifests itself gradually. Usually it was not possible to put the device on charge right away; we had to move the charger a little in the area of the connector. The cause of the breakdown is usually careless use of the phone. At risk are people who like to leave their smartphone charging but continue to use it. Also, the cause of this problem may be the age of the mobile or simply a poor-quality connector. Cheap chargers also greatly loosen the connector socket and dislodge the contacts.

You can try to solve this problem yourself.

Turn off your device. Remove the battery if possible.
Take a small thin object (toothpick or needle).
Insert a needle into USB port and pull the small fastener up. This should be done very lightly and as carefully as possible.
Insert the battery. Check if your phone is charging.

If you couldn’t fix it yourself, then use the services of a specialist. The problem is solved quite quickly and inexpensively. After repairs, try to charge your phone less often. Try to charge your phone fully once a day.

Operating system problems

Due to a failed update or harmful viruses The phone may stop showing that it is charging. These problems are solved differently in different operating systems.

Android

Use programs to optimize system performance (CCleaner, Clean Master, Smart Manager).
Install an antivirus and scan your device for viruses.
Reset the system to factory settings. To do this, find the “Settings” menu item on your phone.

Find "Backup & Reset".

Then select Factory Reset.

If the problem was precisely operating system, That last method will definitely help. Just don't forget to transfer all important data to the flash card.

iPhone

Force restart your iPhone. To do this you need to simultaneously press Home buttons and Power for about 30 seconds.
If the problem occurs after the update, you can simply cancel them. To do this, connect your device to your computer. Open iTunes and make a backup.

Windows Phone

Reboot your phone.
Try turning off the device and charging it for 20 minutes while it is turned off.

Battery fault

If your phone won't charge, then the problem may be with the battery. Like any thing, it has its own service life. It is especially shortened if the mobile gets wet or falls. If it is possible to take out the battery and examine it, then be sure to do so. Pay attention to whether the battery has any deformation, swelling or bending. This is a sign that the battery is not working.

If the battery is non-removable, then there is another way to check for defects. Place your smartphone on the table and try to rotate it around its axis. A swollen battery will cause the phone to spin vigorously.

When buying a new battery, try to buy an original one from the manufacturer. They cost more, but the quality is much better than third-party developments.

Problem with the controller

If you have checked everything you could and the phone is not charging, then most likely the problem lies in a broken controller. It is he who is responsible for ensuring that the phone is charged. You won’t be able to identify the problem yourself, much less fix it. It is better to contact a specialist who can accurately determine the cause of the breakdown and fix it.

The phone has become such a part of our lives that without it you feel like you have no hands. But if your phone has stopped charging, this is not a reason to despair. Replacing a battery, connector, or charger is quite quick and inexpensive. It’s much worse when, for example, the screen glass of a gadget breaks. That's where the repair can cost as much as buying a new phone. Here the problem is local in nature and is solved very quickly.

If the phone stops charging, then this is an extremely unpleasant problem. Most often, this is encountered by owners of old batteries that have almost expired - their service life is 3-5 years, and with the current load on a mobile device it can be less than two. However, the reason is not always 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

There are several reasons why the phone does not charge from the charger, 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 is more difficult 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.

The phone shows charging, but does not 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:

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.
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.
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.
Battery failure. The battery has outlived its usefulness and all that remains is to replace it.
Calibration failure. The smartphone may not correctly see the battery capacity; to do this, it needs to be calibrated. Discharge and charge several times.
Background applications. If you do not use your smartphone while charging, but it still does not charge, then the processor may be spinning a large number of 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.

Problems with storage. 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.
Deep discharge. If the phone is discharged to 0 and does not charge, then the battery may have gone to waste. deep discharge and the controller no longer passes current, in order to revive it you will have to use a universal charger.
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.
Firmware glitch. This can happen due to an unsuccessful software update, a virus infection, or a 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:

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.
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.
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.
Battery problems. If the battery has become unusable, it may show that it is charging, but in fact there is no more capacity left in it and there is simply not enough power to start 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. Also possible reason in the “non-native” wire.

New phone or battery won't charge

Manufacturing defects. 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.

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.
Deep discharge. If the device or battery was stored in improper conditions, then the battery could go into a deep discharge, 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.
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.
Incompatible battery. New battery may not charge because it is not compatible with your phone. You need to be more careful when choosing.
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 old battery OK

Important! If you have new phone or battery, then you should not repair it, as you may lose the 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.

Many users, when trying to connect their phone to a computer using a USB cable, are faced with the fact that the computer does not recognize the connected gadget. The connected device is charging, but there is no access to the smartphone itself and its internal contents. I also encountered this synchronization problem, and in this material I will tell you why the computer does not see the phone via USB, and I will also share various methods for solving this issue.

I would divide the whole complex of reasons for the problem that the PC does not see the smartphone via a USB cable into hardware and software, and below I will list each of them, simultaneously providing instructions for correcting it. But before using the methods I indicated, try restarting your computer and smartphone - this does not help as rarely as it seems. This problem mainly occurs with devices Samsung, Lenovo, HTC, LG and Fly.

So why doesn’t the computer see the phone via USB, but charges - hardware reasons

1. The cable is damagedUSB. It often happens that the cause of this dysfunction is damage to the USB cable itself. Cables from little-known or “non-name” manufacturers do not have a large margin of safety, and can fail within just a couple of months from the start of operation, and as a result, the computer will not recognize the connected phone.

In addition, even the most reliable cables from global brands are subject to stochastic damage - they can be accidentally damaged during use, chewed by pets or spoiled by children. Therefore, first of all, inspect your USB cable for the possibility of mechanical damage, and, if the cable is externally intact, try using it to connect your device to another computer. If the device is not recognized on another PC, try replacing the cord.

2. The port is damagedUSBon the computer. USB ports used on a computer are also susceptible to various mechanical damage, including damage to the USB controller, as well as south bridge motherboard. Try inserting the cable into another USB connector, if this did not help fix the connection of the phone to the PC, follow further advice.

3. The cable socket on the phone is damaged. Has water entered the smartphone socket or is it damaged? If yes, then it needs to be replaced.

4. Try to remove the battery. According to reviews from some users who also had a problem with the computer not seeing the phone through U-ES-BI, removing the battery from the smartphone helped.

Turn off the battery, remove the battery from it for a few seconds, then put it back, and turn your device back on.

If nothing helps you fix this problem, then describe your situation. What have you already done and what is happening to your Android device at USB connection gadget for PC in the comments, I will try to help not only me, but also everyone who has encountered this problem.

The computer does not see the phone via USB - software reasons

After describing the hardware reasons, we list the main ones software reasons, if your computer still does not recognize cellular telephone, connected using USB cable, follow further instructions.

1. Working with the settings.We go to the settings of our device, select “Memory” there, click on the three dots at the top (Properties), select “USB connection to a computer” and check the box next to “Media device” (“ USB drive"). If you have a tick opposite USB usage like a modem - remove it.

Must be enabled on PC Windows service Update (for downloading phone drivers) and new device discovery service. Don't forget to unlock your phone when connecting to your computer, this is important.

If you are a conservative and have Windows XP, download the MTP (Media Transfer Protocol) for XP from the Microsoft website and install it on your computer.

2. If your drivers are lostUSB-ports, the computer may not see the phone.If drivers for USB ports malfunction, the latter simply stop working. To fix this problem install USB drivers from the “native” disk with drivers for the motherboard of your PC, or download fresh drivers on the motherboard manufacturer's website.

Also, due to some reason, power may be turned off for a number of ports.

3. Device drivers have crashed. Go to Device Manager and see if there is a question or exclamation point in the "Portable Devices" section.

Check if your device is there and make sure it is working properly by right-clicking on it and clicking “Properties”. If it is not there, or you have doubts, remove the driver, disconnect the phone from the computer, and then turn it on again, and let the system install the driver again. This may help solve the problem that the smartphone does not connect via USB to the computer.

It will also not be superfluous to go to the website of the manufacturer of your smartphone and download the latest drivers for it to your PC (for example, there is special software for Samsung Samsung Kies).

4. Install the updateK.B.3010081 (K.B.3099229). For Windows 10 owners, you may need to install update KB3010081, which is responsible for working with Windows Media Player. This player directly related to normal operation MTP (Media Transfer Protocol) services, so download and install the update data.

Also common cause There may be an unreliable build of the OS itself on the PC. Only reshuffling Windows will help here working version.

5. Custom firmware is not working. The desire of many fans to play with the firmware for their Android device can do them a disservice in the form of the device’s failure to work normally with the computer. Try to restore standard firmware or restore from backup (if available).

There are no drivers for the phone on the computer

Although, usually, a computer with the latest OS detects and sees a smartphone via USB without problems, the opposite cases may also occur. Try looking for a driver for your smartphone on the Internet, sometimes a driver for similar models may be suitable of this brand.

The phone may not be detected by the computer due to viruses

Trite, but all kinds virus programs may block work with external mobile devices. Try checking your computer with Dr. antivirus applications. Web CureIt!, in some cases this may help.

If the problem of the computer detecting a mobile device is not resolved, reset the settings

If still, your computer does not see the phone via USB, resetting the smartphone settings using Hard Reset. Go to your phone's settings, select the menu item " Backup", and in it select "Data reset".

But I warn you right away that you will lose your files and settings that are in internal memory phone (the files on the SD card will remain untouched), so this item should be used only as a last resort!

Conclusion

As you can see, problems with the lack of visibility of a connected phone on a PC can be both software and hardware in nature, and there are a considerable number of such problematic factors. I would advise you to first pay attention to the probable mechanical damage in the cable and device, and only then switch to software methods.

In many cases, simply rebooting the smartphone (temporarily removing the battery), as well as working with the phone’s USB connection settings, can help. If all of the above does not help and the computer does not see the phone via USB, but is charging, then you may need to contact a qualified service center.
