1. Restart the phone
< br >
It seems that there is no technical content, but in fact, there are many cases that the problem of mobile phones not being charged has been solved by this simple way. Sometimes processes and software running in the background can cause system conflicts and hinder battery charging. Restarting the phone will shut down all processes running in the background of the device. So, before you charge, try turning off your iPhone, Android phone, and then turning it back on. In addition, in the case of a phone crash or a fault, restarting is also a simple and safe repair method.

2. Replace the charging socket
< br >
When the charging power supply is weak, your phone will definitely charge slowly, and may even be unable to charge the battery. For example, the input power needs 220V, but if you plug it into a 110V socket, of course, it will not be able to provide enough power for the phone to charge quickly. In this case, although the phone is charging, it is understandable that it takes a long time to fully charge. Therefore, you should check and replace the charging socket to see if there is any improvement.

3. Check the electricity in the house
< br >
When the current output of the power supply at home is unstable, it will also lead to the problem of the phone being unable to charge. Plug a lamp into the same socket as your phone charger to see if the bulb sometimes flickers.
< br >
If it blinks continuously, it indicates that the current in your home is unstable, and vice versa. If you can't do it yourself, ask an electrician to check it for you.

3. Repair the USB port
< br >
Inside the charging port is a metal surface made up of a number of contacts, called connectors, each of which touches the corresponding metal strip on top of the charging cable. It is possible that these contacts are not good, repeated insertion and removal caused by the connector bending, or collapse.
< br >
All you need to do is turn off the phone, remove the battery as much as possible, and then use a small tool like a toothpick or sim card pin to pry up the contacts inside the USB port of your smartphone or tablet. Be careful to be gentle or the contact may break. Then reinsert the phone to charge. In most cases, after doing this, the problem of not being charged will be solved.

4. Clean the fluff of the phone charging port
< br >
Do you often carry your phone in your jeans pocket? If so, fluff may be the culprit keeping your phone from charging. After placing the phone in the pocket of the jeans for a period of time, the fluff will gradually block the USB charging port and get stuck in the charging needle, resulting in poor contact between the phone charging port and the charger. In this case, you can blow hard into the charging needle to allow dust or fluff to fly away, or you can pry it out with a small object.

6. Replace the charging cable
< br >
The most vulnerable part of the charger is the data cable, not the large adapter that plugs into the socket. This is especially true for users of Apple products, as Apple's expensive and proprietary Lightning cable is even more vulnerable.
< br >
The easiest way to check if the data cable is damaged is to test with a different charging cable, and if the new charging cable is working properly, the one you are currently using is damaged. If not, the charging cable is ruled out as the cause.

7. Replace the adapter
< br >
If there is no problem with the charging cable, then you should check the adapter again, especially if the charger uses a separate charging cable. The problem with many chargers with removable charging cables is that the USB port becomes loose after a long time of use. Try to plug the charging cable and adapter back in tightly, if the problem persists, it may be that the adapter is damaged and can only be replaced or taken to a professional for repair.

8. Replace the battery
< br >
Batteries in cell phones degrade over time. Frequent high-intensity charging and discharging will result in faster battery depletion. Usually used within 2 years of the battery will not be charged into the problem. But if you have been using it for 2-3 years, it is likely that the battery has reached its useful life.
A Huawei mobile phone cannot be charged due to the following reasons: The charging head is faulty, the battery is damaged, and the charging cable is damaged.
First of all, we can try to replace the charging head and charging cable, and if it is still unable to charge, we need to consider whether it is a battery fault. If the battery is damaged, we need to replace it.
In addition, if the phone is placed for a long time, the phone can not be charged after the battery is consumed, we can use some techniques, such as connecting the phone to the computer or the power cord to charge, and it is best to use the original cable to charge.
At the same time, users also need to pay attention to protect the battery life when using the mobile phone, avoid frequent charging or overtime charging, and pay attention to control the power. In short, we need to judge according to the specific situation, if the above methods can not solve the problem, need to consider replacing or repairing the mobile phone.
1, the mobile phone can not be charged, of course, we have to find which piece of the problem, only to find the problem to the right medicine. Let me go step by step from the simple to the difficult to check what the problem is.
2, first of all, the phone is connected to the charger and plugged into the plug-in board to see if it can be charged. If you can't charge, the current possible problems are: the charger is broken, the cable is broken, the phone interface is broken, the battery is broken, and the system is faulty. And then we can eliminate that.
3, change a cable or change the charging plug, and then charge to see if you can rush into the electricity, if the rush into the electricity, it proves that this is the problem, change a cable, or change the charging plug. When the charging plug is changed, pay attention to the same parameters as the current and voltage of the original charging plug of your phone to prevent harm to the phone. If you can't rush, the possible problems are: mobile phone interface problems, battery problems, system problems.
4, the battery is removed (can not be removed, don't forcibly grab it), the use of universal charge to rush, if the charge is the problem of the mobile phone charging interface, if not, then continue to investigate the possible problem: battery, system.
5, change the battery to try to be able to rush into, if the battery can be charged, it is likely that the battery is scrapped. Just change the battery. If it doesn't, it's a system problem. Pay attention to the battery is best original or buy good quality business battery, I once because of a bad quality battery and broke the phone, everyone must pay attention!
6, many people do not understand how the system can affect the charge, I take the Android system as an example, the Android system has a file in the log is to record the battery information, if the battery information is wrong, it will lead to the phone can not be charged.
If the charger and cable are damaged or the charging interface of the mobile phone\/tablet is foreign or deformed, it may cause failure to charge or intermittent charging. Please ensure that the charging interface is clean and free of deformation before charging, and check whether the charger and cable are damaged, and try another charger
