Hi!
Since updatets was installed battery drops very fast. I return to original and cleen all my programs. Now is the same 
Can I return to old android? I think that new Android have problems with using battery. For me is very importand my battery to have long live.
Some people say that updates must be settled down for a couple of days to get more battery hours. But it was not the case for me. I found that if I let google or other apps to access my location even when the gps is off, it drains battery. I disabled location services for google and my battery turned back to normal. You may want to try that. Also check for other things like syncing, nfc etc.
Thank you!
You are very kind to help me! 
I turn it off allready, but the same. In the same plase everithing is off, thay are not active, but the same.
It was perfect before updates to new Android...

Google Logation is off too. I check now. Some other Ideas? 
Try to boot the phone in safe mode,see if the same drainage occurs:

You should stay in safe mode for about 1-2 days.Report here.
Thank you!
I will try and I will write what hapend

Ok,waiting for the reply.
you need to let new SW setteled downl..it might take while...for me it took 1 week
after that battery usage returned to normal
some things that drain battery are "auto sync...data connection...location services...high screen brighness"
also if you have apps like battery saver or antiviruses uninstall them
You are welcome, my suggestion didn't actually help. Thanks for the flower
you're very kind, too.
Try other suggestions, I hope they help. If they don't then maybe you could tell us more about your problem.
Does the drain happen when you are actually using the phone, or when on standby? Is Stamina mode on?
Also, take a look at battery usage graph/list and see which apps come on top and maybe upload a screenshot of that.
I try but nothing happend.. Can I will try to downgrade and I will write here.
Thank you everyone!
