Dear users: Too many programs running in your phone will also consume a lot of power, you can use Android Optimizer to close some apps that are not used temporarily. If it still doesn't work, it is recommended that you contact the Lenovo repair station for testing.

Try to use the cradle charger as little as possible, connect the phone to the appropriate charger, if there is still a problem with the proper operation, you can try to change the battery. Try not to charge in a very cold environment, as this may cause the battery to not be fully charged.

I saw that your situation is generally due to the mobile phone battery itself, not energy consumption is so large, if it is not full, the mobile phone battery should not show full charge, I personally recommend that you consider changing to a Pinsheng battery to try, super core chip, the same as the original.

It is a problem with the phone battery, and it is recommended that you replace it with a new one.
