ok guys. I usually charge my iPhone with the wall charger. But sometimes i plug it into my macbook pro to transfer songs, and larger apps and stuff. But i have noticed the last two days that while plugged into the computer, i have LOST battery life while "chargeing" I will look at my useage. Where as it was 2 hours or so when i plugged it in, the useage shows 4 hours and 30 min of useage time.. while not doing a single thing on the phone! i turned off the phone and turned it back on. I noticed it was doing the same thing today. anyone know why?? simplify all of this: my iphone is LOOSEING battery while plugged into my computer?!
