iPhone 4 bought at launch, dies mid day while in standby. I brought it to the store, they restored it and said the os was reading the battery wrong. Ok, I went with that. A week later, no dice. Today I'm told I need to periodically open the multitasking bar and kill every app shown. Was told that every single app shown in that list was draining my battery. I even talked with the manager and he told me the same thing. I'm not buying it and I'm pretty bummed that Apple is going with this. After all, if we have to task manage we are "doing it wrong" right? I know about the API's and suspended state and which apps should be "running" using battery and which are idle or saved. Or so I thought! I keep up with this stuff, I know how it's supposed to work. Now according to Apple retail, I have to remove even the settings app from the quick launch bar to save my battery life. I tried to explain to them that I understood the os to use certain API's for actual background use of apps... I didn't bother going further because they denied that's how it works. They say you have to regularly clear out all the app icons, including ones for settings and others like it. I was flummoxed.
