Received my new Iphone 4 just last week. Like it so far. Have become concerned about the fact that it has to be charged on a daily basis. I do not us it that much; would think that I would get more than a day out of it. Leaving it sit at 100% charged overnight; it will loose 50% of it's charge by the morning. I have turned everything that I can of in the settings menu. I have a app called "System Lite" that shows what applications are running on my Iphone. It shows 15 as running. That can't be good. Is there a way to shut this applications down so that they do not use any of the Iphone's resources??
