Nexus S 4G Battery

I'm getting awful battery life. i have brightness all the way down, GPS off, synch on half the time, off half the time, show some screen animations, vibration for keyboard off, wifi on at work/home, off elsewhere, static wallpaper (no live wallpaper).
 
I get about 10 hrs before it needs sharging (fairly heavy use). I'm ok with this. I also prefer using the word sharge.
