It seems like my battery is getting drained semi quickly. I noticed when I go to the multi tasking menu that pressing and holding an app makes them shake and have a delete logo. When I delete the apps like games, and reopen them it looks like it does close out of the app. I am just confused as to whether I am on the right track here? It seems like simply pressing the Home button on Pandora now doesn't close out of the app competely because it auto resumes the music playing when you reopen it. Sorry if this is a dumb question, but I just want to help my battery a bit. What exactly does deleting the App icons out of the multitasking bar do?
