The use of mobile phones is also very extensive now. For the use of mobile phones, I believe many people will encounter the problem of not charging. So what's the reason why the mobile phone can't be charged? Follow Xiaobian to find out.
1. Let's first see if it's a battery problem.
2. If the condition allows, the cell phone can remove the battery and use universal charging to try to charge it.
3. If the battery can be charged, it indicates the problem of data cable or mobile phone socket. If not, then it's the battery. If it's a battery problem, Xiaobian has a small way. Wrap the battery in a newspaper and put it in the refrigerator for three days. Then take it out and dry it in a ventilated place for a while. Then the battery will be OK.
4. If there is a problem with the phone socket, try to wipe the dust inside the interface with a brush or a small brush. It may also be caused by excessive dust accumulation on the interface
5. If you can't wipe it, it's recommended to change a socket or data cable. It may be caused by poor contact of power supply.
6. If the above methods still can't make your mobile phone charge normally, it is recommended to go to the local maintenance point for maintenance.

1. Power off and charge test.
2. Replace the charging position and eliminate the charging problem caused by the intermittent connection of the socket
3. If conditions permit, replace the original charger for test. Or send it for repair and inspection
4. When the phone is powered on and charged, for example, a third-party plug-in such as a charging doctor is installed on the phone. It is recommended to test after unloading.
5. Check whether there is any foreign matter in the charging interface of the mobile phone, such as liquid inlet and foreign matters, which cause the poor contact between the charging interface of the mobile phone and the charger. If this situation, it is recommended to send it for repair as soon as possible.
6. Back up the data of mobile phone (phonebook, SMS, picture, etc.) and restore the mobile phone to the factory settings (enter the mobile phone settings - reset - restore the factory settings).
7. Try not to answer or make phone calls during charging. A good habit is to turn off the phone when it is charging, so as to ensure high-quality charging effect. In the process of normal use of mobile phone, try to conduct healthy charging every time when charging, that is, when the power is less than 20%, do not wait until the power is exhausted to recharge, so as not to affect the service life of mobile phone battery.
8. For the users who use the voltage regulator converter to charge the mobile phone, they should connect the correct mains power for charging according to the requirements of the charging instructions. In general, the domestic market power is 220V, while in foreign countries, such as Japan, the market voltage is 110V. Therefore, if the mobile phone is charged abroad, it will be unable to charge normally due to insufficient voltage. The user who charges through the data line shall ensure that the normal 5V voltage is provided to the USB interface.
9. There may be a problem with the quality of the battery itself. A new battery can be replaced. Either because the battery is used too long or for some reason, the positive and negative poles of the battery are short circuited and damaged.
10. It may also be caused by the quality problem of the mobile phone itself that the mobile phone cannot be charged. In this case, it is recommended to get it to the mobile phone repair shop for repair. If the mobile phone is in the warranty period, it can be returned to the factory for repair.
