Hey, about 2 weeks ago I noticed weird behavior from my battery.
When phone is locked battery drain is too fast.
It seems that the "android system" keep the phone awake for long periods,
And that the "android os" keep using the cpu.
I've been trying many thing - wifi, location, sync etc but nothing helped.
Used system panel to monitor my battery life,
Here are the results from the last 8 hours (100% at morning till now)
Attached photos - Overall battery usage, Screen on, Android System, Android OS, System Panel and More detailed system processes,

In the first 3 system processes there is high cpu usage even when screen is off..
(Top one, System, attached)
I know the overall battery using seems to be good,
But it's only because I've been using the phone the whole day.
The problem is when I'm not using it - it drain very fast with no reason.
I don't remember any change I've done (didn't update the software, maybe an app),
And before that the battery life was great (and so they are now if I'm using the phone continuously without "putting it in my pocket".)

Well if i look at your screenshot i could say it was normal, the one that draining your battery is your screen (based on your ss). But in other way you can download some apps to control your kernel (e.g kernel auditor) and swipe to "kernel samepage merging" tab, look if its on or off, if on just turn it off and see your battery life then, it happen to me sometimes.
