I'm just adding to the chorus of what appears to be many many others that are experiencing this serious flaw and I hope a fix is being worked on to roll out as soon as possible.

After any major update, you should always run a cache wipe procedure. It flushes out the old OS files. This will NOT cause you to loose any personal settings or apps.   Try this.

1. Turn phone off

2. Hold Power , volume up and home button till you see phone turn on and os recovery loading

3. Now mark the entry "Wipe cache partition" with the volume down key. With the power on / off button the entry can be selected selected and the process gets started. This usually takes only a few seconds. Then the previously displayed menu appears again. Now select the first entry with "Reboot system now" and run the command again with a press of the power button. Your Samsung Galaxy S6/S5 will now reboot.

4.Thats it! enjoy your phone again. Smiley Happy

Software updates should be just that, an update to help your phone preform better. I am alarmed to read that is not the case here. I want to dig a little bit deeper to gather a few more clues, how long does your battery life last now? Have you looked at your battery life manager to see which particular functions are using your battery the most? http://vz.to/1S0foUh

AmberK,

I followed the instructions given by Cybergoobr on clearing the cache partition and that seemed to have helped and the battery drain is not nearly what it was.  My suggestion would be that when future software updates are done that after it's complete, instructions are given as to how to clear the cache partition so that people don't run into this issue.

Thanks

I've been having serious battery drain since updating to Marshmallow.  I have cleared the cache twice, according to directions from @VZWSupport, but it still drops to 15% in about 15 hours.  I don't watch videos. and seldom talk on the phone.  This past 3 weeks I've been almost entirely on my home and work wifis -- no roaming or searching, and Bluetooth is turned off.

I will be traveling soon, and need my battery to last like it used to.

My phone will not do that,when I do the combination of buttons all I get is recovery.... in a blue lite at the left hand corner of my phone.Then sometimes I can get to the 3 options start normal.....reset the phone....or safe mode.

kathy65793,

Let's wipe this cache. I know I personally had to do this on my phone. I actually had some assist me as I needed to press all three buttons at the same time. With doing just two it does put it in Safe Mode. We encourage you to try again.
