In Galxy android 6.0.1 cyanomod. New battery. One day the telephone fell down and the display crashed. It has been replaced with a new one. But since then, the battery when using the phone discharges extremely quickly 1% in 3 minutes and of course the screen heats up strongly at the height of the flash. It sometimes heats like it would hang, because even if I turn off the phone, it won't cool down anyway, only the phone off and on. With charging the phone no problem there is no heating, but sometimes you can see how the charging LED blinks slightly. Is going to diagnose and fix the fault yourself.
