I'm having a similar issue. I'm sure I have a rogue app that's keeping the main android process awake. Kept it awake for 45 minutes out of 6 hours today.

Turn of "Smart Stay", that feature constantly runs and it drains ur battery
I turned mine off and noticing a good difference

Smart Stay does nothing when the screen is off. Using diagnositcs, it never shows up as a significant user of cpu or battery.

There are relatively simple ways to figure out what's killing your battery. First step is to look at battery stats, and from that screen tap on the graph and see additional detail about radio use, then tap on the Display row and see what screen on time is. Capture all 3 screens and post here.

Wakelock Detector can tell you what apps are keeping the system from sleeping. Remember that any background syncing (email, facebook, twitter, Google) will cause a wakelock while it runs.

System Panel will detect and report on CPU usage by apps and system processes. Other than screen and radio, CPU usage is good indicator of what's using battery.
