captainMADApart from drain , everything else you complain about has to be enabled from settings and what do you mean by no background process just turn off super clean if your are having issues with appa in background,
Things are getting worst day by day in terms of battry
I kept phone idle for 8 hours,it drained upto 18%
And 1.no always on display
2.no screen wakeup on notification
3. No background process
Why thes things happening??
