since i flashed stock lollipop a30 ( was using cloudy g3 2.2 previously) charging speed has gone really bad for me
its 1% per 3 minutes ..
did a clean wipe berfore flashing.
calibrated battery few days ago with a software but that didnt cause any issue n the phone used to charge full in 2 hours max
any idea what might be the cause now ??
