ive been noticing ever since 2.0 and downloading apps, my battery life has suffered significantly. at the end of a business day, my phone has 10% battery life. i decided to look at the usage of the phone today and it said i used the phone for 9hrs and some minutes all day today after my full overnight charge. there is no way that this is possible since i know im never on my iphone that much, even if i did have the time, i would just get sick of playing with it. is there a way to see what apps are actually running in the background? apple said no apps in the background. but i just read one of the IM clients will actually run in the background even when the phone goes to sleep. id like to get my battery life back...anyone got any suggestions? tia.
