As we know mobile battery life is the life of your phone,
Charging the battery to 70% increases battery life.
Also if the battery is getting heated up during charging it loses life rapidly.
This app sounds an alarm when it is getting heated up over a preset temperature like 40-45 C.
Also, you can set the charging limit like 70-80%.

Close all other apps while charging.
Switch off wifi, Bluetooth, and location if not using them.
Keeping data off or activating flight mode will greatly help in keeping battery temperature down.
