I use Advanced Task Killer and even after I kill all running apps (Facebook, Google App Store, voicemail, video player, just to name a few) they all seem to come right back on, with a few new ones showing as running. My battery life is abysmal. I haven't used these apps - they just appear. Any ideas? P.S. I've done all the things to enhance battery life - screen brightness, hepatic feedback, no Bluetooth, GPS off, etc.
