First of all, your screenshot aren't (yet!) visible. So it is hard to tell what can be the problem.
I had similar problems with android stayed awake and draining the battery, but in this couple of times it was only needed to restart my phone and nothing else.
I your case, maybe is some application that keeping awake your phone?
Maybe antivirus or some kind of app that is always active, (e.g. Facebook app, Email, etc.)
Last problem I've noticed is mediaserver and Walkman app as cause of my problem with battery drain.
You said you have flashed your phone? It takes some time for Android to settle down after update. So if you upgraded your phone when you bought it and now reinstalled it, then it may still be settling down.
On the other hand did you make discharge (under 20%) and charge of your battery after update?
There are many possible reasons, but some of them are more likely to be, then others.
EDIT: Well meanwhile pictures and another suggestion came on 🙂
