This is something that happens on whichever ROM I've tried. For a couple of days everything is great and then suddenly the phone shows constant awake and screen on, even of the phone is locked. You can see it on the attached screenshots, the blue line when the phone was awake with the screen on is actually from when the phone was locked with the screen off. After I wiped the dalvik and cache, it went back to normal. Anyone found a solution to this?
