Battery draining even on airplane mode
After using(in emergency) a fake charger , the battery life slightly decreased 89 to 80% and heating issue started..
battery has been replaced but still have heating issue and new battery getting drained much before the normal timeframe (getting 1% reduced in 10 minutes in airplane mode with screen off ). All apps has been deleted. CPU usage still appearing 20-40%
what could be the issue and what best can be done to resolve this
please suggest, any help would be highly appreciated!!
