Ok the good news is that it doesn't appear that you have something in the background keeping your phone awake when the screen is off.
You might want to check the phone signal graph to see if it's fluctuating a lot. Also, Wifi Analyzer can tell you if you're on a network with channel conflicts, that's not the best thing.
If you're running a live wallpaper, that's not your battery's friend.
@samakhan - please look up a few posts, I have instructions and a link for posting screen shots.
