4 possibilities
1. Change the charger, maybe the charger is broken
2. Changing the battery may be that the battery has been used for a long time, and the general life is 1 year
3. It may be that the battery power is too low, because the current battery power is automatically protected as long as it is below 3.6, so it is impossible to charge it again! In this case, you can use the universal charge for 5 minutes, and then charge it
4. The worst result, take a look at the charging interface of the charger and the phone, it may be too much force when charging, and the interface is plugged bad! Then you have to go to the repair station and pay for it
A common cause is aging cell phone batteries. This problem usually occurs when mobile phones are used for a long time. At this point, you can solve the problem by replacing the battery.

2, it is also possible that the phone charger current is insufficient, which will lead to very slow charging, and even charging is not as fast as power consumption. At this time, we need to replace a charger with a larger current output.
one
Shutdown charging test.
two
Replace the charging position and eliminate the intermittence caused by poor socket contact.
three
If conditions permit, replace the spare charger for testing.
four
If the mobile phone is equipped with a third-party plug-in during charging, uninstall it and test it.
five
Check whether there are foreign objects in the charging interface of the mobile phone, such as liquid intake and debris resulting in poor contact between the charging interface of the mobile phone and the charger, which is recommended to be repaired as soon as possible.
