my SM-G906s doesnt enter sleep mode. the battery stats show that its awake the whole time. and android sys is eating up most of the battery power. and the phone heats up(powers button area) at times. im running the latest NK1 4.4.2 unrooted firmware.
Please help me figure out the issue!
I have the same problem whereas I'm on the stock rom or miscom's one. I installed Greenify (it works without root) and wakelock detector. Sometimes I managed to have 50% of deep sleep.
But others times, others apps are acting crazy like Gmail which kept my phone awake half of last evening.
I didn't find any satisfying solution apart from cutting off the data connection which I need...
