If the battery is reduced while the phone is charging, it is recommended that you try the following methods:
1. Try to use the original charger to connect to the home power supply.
2. Keep the phone on standby to charge or turn it off to charge.
3. If conditions permit, replace the battery
If the problem still exists according to the above methods, please bring the purchase invoice, repair card and machine to the Samsung service center for inspection. Due to the inability to charge the situation may be caused by the battery, charging interface, charger and other reasons, in order to provide you with more targeted help, professional after-sales engineers are needed to help detect post-processing.
Note: If you are playing a game or watching a video while charging, the charge may become less and less.
