Updated to Android 6.0.1 (Marshmallow) several weeks ago and have been experiencing sever battery drain. When looking at battery status top users are consistantly Andoid OS and/or Google Services.
I have wiped cache, run in safe mode, turned off auto backup, wifi and bluetooth. Nothing seemed to help. This weekend I decided to perform a compelete factory reset and only install minimum apps back onto phone: Samsung Pay, Gmail account and 2 banking apps.
It does not appear that phone every goes into deep sleep and Android OS is keeping phone awake for extended times.
This morning I pulled phone off charger at 7:30am, 15 minute ride to work and phone has been on desk all day. Wifi and Bluetooth were left on. Made no phone calls, no Google searches, sent 3 text messages and accessed banking app for < 60 seconds.
~9 hours later battery is showing 72% with Android OS and Google Services as top power users. Battery graph and Android detail attached. Had screen on for 3-4 minutes taking screen capture and reviewing battery information and now with phone off for ~20 minutes battery now showing 65% (see last photo). Need help as can't use this phone when traveling for work with this battery life.
Hard to believe solution is to replace a 14 month old phone. Before update to Android 6.01 which occured 2-3 weeks ago the phone made it through an entire day and had 40%+ battery life at 10:00pm.
After update phone is routinely below 20% before 5:00pm. No apps added since update and have tried factory reset. Seems to point towards update as causing the battery drain impact.
I am experiencing the same thing. Everthing is set to default. No 3rd party launchers or anything. Battery is going down faster than before update. My phone is only 2 months old.
