Android system battery drain

Hi,
Im getting bad battery life in the past 2 months, I tried to flash the latest stock rom, rooted the phone and deleted bloatware, and im also using greenify.
after doing all of those things im still having trouble with battery drain.
at GSAM battery monitor it says that the app usage is 62% (screen is 31%)
20% goes for Android system, and 13% goes for Kernel (Android OS)
at settings - Android system 25%, 15% android os, compared to 15% screen.
Is there anything left that I can do it order to fix this?

Android System and Kernel (Android OS) draining battery.

My battery has been acting weird these days, It has been losing battery when the phone is not being used. I wiped cache from recovery and it was good again, but after 1 day, the drain came back. I used GSAM to see what was draining my battery and I saw that Android System used 22% and Kernel (Android OS) used 10%, it means that both used 30 of my battery, is that normal or what ? I have 6.0.1 Thanks.

Thanks !

Extreme battery drain by android system

Hi friends....
I have the exynos version of s7 edge and am suffering extreme battery drain... when the phone is off it still costs around 2% in one hour and sometimes without even using the phone feels hot in hand.... i have tried everything that was on youtube and all the methods in the xda thread.... twice factory reset my phone and tried resetting as well but the results are same after i update the apps on my phone....
The major reason for the battery drain was 1) wifi active around 37% and 2) apps usage around 61%....
But i couldn't find out which apps were causing the drain since no apps were listed except some with 1 to 4% of drain....
Any help please...
Ps: am not rooted
