Whenever I end all of the apps in task killer and go back into it they're all opened again. I never even opened some of these. Also anyone know if WiFi uses less battery than 3g?
Some apps open automatically. You don't need to kill them manually, Android manages tasks on its own and kills them off as needed. Just because the app is "open", doesn't mean its doing anything.
Yes, wifi uses less battery than 3G.
Additionally, even with wifi on, 3G will engage as soon as your are out of range of a known wifi network. Win-Win.
