It may be because you do not use lithium battery aging for a long time, you charge it for a while to try to see if it can be good, and it will be bad if it is not good. First change the data cable and socket, and then consider whether the device is too long battery aging, and finally consider whether it is the motherboard problem. The reasons why the battery is not charged from a large aspect can be divided into the inherent internal reasons of the battery itself and the external reasons for the battery to implement charging.
First replace a data cable and charging head. If it is still not charged, it is necessary to remove the machine and test the battery.
