well so far I'm using Facebook app version 2.2. Seems to me much better.Yes because it's always accessing background crap. I uninstalled it and use the website, night and day on my battery.
Yeah I just deleted it again as well. I'll see if I have any battery improvements as well.I fired the fb app several weeks ago and it made a world of difference. Not only is my battery life better, but now I'm not constantly checking fb. I'm free!
