I'm curious what the answer is to this. I plugged my iphone in last night and unplugged it this morning. I text'd a few times and left my phone in standby mode. I went back to make a call and my battery life was at 20%. So on a fully charged battery, from the time I unplugged my phone (about 8a) till I went to make a phone call (about 2p) my battery was at 20% with it in standby mode. I've got facebook, myspace, ebay, one connect, earthscape and about 5 games like iBowl and Cube Runner. Normally after I'm done with a game or like Facebook or one connect, I just click the home button to get back to my home screen. Does that mean my apps are still running in the background? Would it help if I held the home button for 10 seconds? I heard if you do that the app won't run in the background. Do I have to do that for EACH app after I'm done with them? Unjailbroken phone here. wifi is off, location is off, auto brightness is at a good setting, bluetooth is off, latest upgrade.
