Guys need your help. When my Android battery is over 60%, it shutdowns and goes to 0%.My phone Battery is new.What is the problem?
Calibrate the batt. Discharge it completely and then charge it to full without interruption for at least 2 times.
Turn the phone off,press volume up and the power button, to enter boot mode,using the volume down key, highlight the “clear cache partition” press the power key to select “clear cache partition” and eventually use the power key to restart your phone
If a hard reset doesn’t fix your problem then it’s hardware related.
