I want to know if there is a way to turn off multi-tasking. For those that don't realize it yet, every program you open stays open in the multi-task bar until you close it manually. My phone got to 20% battery in 4 hours today with decent use. (new iPhone 4) About 10 minutes of web surfing. 93 minutes of talking. No streaming video 2 Pictures 1 Recorded Video for 3 minutes. My only guess is that since I forgot about multi-tasking that it left everything running. (12 apps) Is there any way to turn it off, and only enable it when I actually want something to multitask? I can't see any reason to have ANY apps multitask now especially since most apps are not updated to support it. In a perfect world, I would have a menu that I can select which apps I want to be able to multitask.
