I keep haptic feedback off - I'm thinking it's a battery killer for those of us who type a lot.
I've just now turned on CPU power saving and screen power saving (but not the setting that flips black for white in the email app - hate that). We'll see how it does. It was doing pretty good without any of that before, so perhaps this will really help things.
Either way, the standard battery on the GS3 is giving me what the Sedeio extended battery was giving me on my GNexus LTE.
