What do you have running on your phone?
If you are on a mac you might as well use Pwnage and upgrade to the latest version of the OS. That may clear some things up.
Then you gotta be careful of what you install. I was having some aweful battery life until I removed Backgrounder (Even though I was almost never using it) then I started getting much more.
I don't have hardly anything running (i believe🙁). I DON'T HAVE the backgrounder thing installed. All i installed since i JB & unlocked was asbattery, a profile for MMS activation, memtool and the ultrasn0w unlock. Plus about 3 or 4 new apps from the app store. That's it and i hardly use my phone now because the battery is draining too fast. It has been in my pocket from 8:15am today and now its at 25%! I was on the facebook app for about 20 mins and checked my emails today. That's it. NO GAMES, NO SAFARI SURFING.😡
