Unbelievable Battery drain G900F

[rebelbet]

First of all im happy to find you !

Then i have a big problem with battery drain and i cant find a way to fix it.
It's little unbelievable but I have this battery ... With marshmallow, btu last version.
I bought a new battery, but the results are same.
I did a full factory reset and install only Rom with a gsam, to find what drain the battery. I leave the phone , no "play" with it, and the results is over 6% drain per hour!

Close Google back up, auto brightness, weather app...and many apps, don't need as Polaris office, i put out SD card





I try something different yesterday. Downgrade to Lolipop, but i have again drain 7-8% per hour, without do anything at phone! I dont install any app from playstore except Gsam.

I try to find a solution at forum, but unfortunately i dont find same problem...
Thanks for your help!

There are always background services running so some drain with no other activity is normal. With Marshmallow and Lollipop it takes a few days for the battery optimization to kick in for apps that aren't in constant use. One thing that does stand out in your screenshots is the Phone Radio using 28% of battery life, but this could just make up a higher % due to lack of other apps running. How is the signal where you are testing?

It's no so good, but I change to 2g/3g for better signal
