1. The charging cable is not tightly plugged or damaged. You can re-plug it to confirm.
2. The temperature is too low, you take the phone to blow the hair dryer for a while, or stay at the room temperature of 22 degrees for a while, 20 minutes is certainly enough, and then charge it, you can fill it.
3. Interface problem, remove the battery (can not be removed, don't forcibly grab it), use the universal charge to rush, if the charge is the problem of the mobile phone charging interface.
4. It may be that you can't full or turn off the charge while playing.
5. Maybe the charging time is not reached or the battery is faulty so it cannot be charged to 100%.
6. Caused by program problems.
7. The output voltage is insufficient, and the output voltage and power of the computer charging can not reach the standard charging voltage and power, which results in less and less charging, and will also have a certain impact on the mobile phone hardware.
