Nope, only 29% used up. I just followed some tips that were posted in other threads (Maybe here as well).
I turned off anything that syncs except for my weather and my sports widget (gotta have my scores
), so now the FriendsStream and the NewStream I have on my homescreens only update when I hit the update bar at the bottom, I also have my screen brightness down to about 25% and I can see just fine, I also turned off any haptic feedback when I press on screen buttons.
Do some of that and see how your battery improves.
