Galaxy S6 bad battery drain after update

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.

 

Any suggestions???

Outside of upgrading to the S7 Edge (which has a fantastic battery btw),There really is no solution.Marshmallow is a BIG update and the S6 is starting to show its age to you.

Re: Galaxy S6 bad battery drain after update

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.

Do you have Google Now launcher? I had it installed on my S4 and it drained the battery. Uninstalled and everything was better.

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.

We recommend including additional information about you device. This would include your full model number, carrier, current baseband, and any information on any other applications you are using. It does appear that you have your WiFi on, are you using this with an accessory that utilizes any S Health applications, the Gear manager, or other application that utilizes bluetooth. This information may help in assist figuring out what is leading to your battery drain.
