my nokia 5.1 phone has an issue in that whenever the battery is zero % it can’t power on again not until you install the software again
The problem is not the software, it’s the battery. You can try to calibrate the battery by doing the following procedure : Fully charge the phone and let it charge 1 more hourDischarge the phone fully until it shut downFully charge the phone again If calibration works, you should get a more accurate battery level. If calibrate the battery did not resolve the problem, your phone’s battery is failing and should be replaced. In order to restore your phone’s battery life and get a more accurate battery level, you should try to replace the battery.
