if your having battery issues install this: http://forum.xda-developers.com/showthread.php?t=1179809 and let it monitor the phone for a few hours then check to see whats draining it. if nothing looks weird your battery is probably going bad.

I didn't get any problems starting up my phone when I put power nap incorrectly and correctly

even if its not the least amount of power used with the script, its still good since some background processes keep this thing running at 768 MHz or higher at times.
