I started seeing much better battery life when I stopped using systray monitor, if you use it try going a day without it.
ALSO have you calibrated your battery??? This is essential if you have wiped battery stats in recovery. I mistakenly thought it was good to wipe everything before flashing a rom so that's what I did, wiped everything every time I flashed a rom. Little did I know I was jacking my battery usage up by throwing the gauge off by wiping the batt stats.
That's all I got, hope it helps
this is my signature
