Android System and Kernel (Android OS) draining battery.

[ShenWeii]

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.
