See what causes it and fix it:
1, the current output is not enough or the plug is not plugged in: this situation is generally caused by charging through the computer, because the usb output is small, sometimes it can not be charged, or the plug is not plugged in when charging, thinking that the phone is charging, in fact, the phone is not charging.
2, charger, data cable connector used for a long time aging or dirty interface can not be charged: you can change a charging head. Or take a fine piece of metallographic sandpaper cut the appropriate size, fold it in half a few times, gently polish it at the interface, and then plug it in to charge it.
3, mobile phone battery damage: If the above reasons are still unable to charge, suspect that the mobile phone battery has been damaged, please go to after-sales testing and maintenance.
