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!!
Unfortunately it seems the aftermarket charger costed you dearly in the end. Unless you had the bad luck to pick up a faulty replacement battery, but that seems a bit unlikely since it shows the same issue experienced with the replaced one, odds are the brick damaged your phone. Such high battery drain is usually caused by a shorted component wasting power constantly. If you feel like it, you may try a further battery but there’s a high risk of wasting further money. Alternatively you may hand your phone to a microsoldering Pro for testing, many work on a no fix no fee basis and would avoid you shooting again in the dark with yet another battery purchase.
Did you replaced the previous battery with a genuine new one or a cheap Chinese brand? Just to make sure, go to Settings, Battery, Batttery Health and double check if they health is above 80%.
