I charged my ipod overnight on my ihome so I am sure that it had a full charge. I went to class in the morning and surfed the web for about 10 minutes. Then at lunch, I got on facebook for about 5 minutes. I locked it and put it back in my pocket and went to class. When I got out of class 1.5 hours later, the ipod was completely dead. I know that there was no way that the battery was even close to being dead before class. There is a small possibility that I left the screen on, but i have it set to autolock in one minute. So that shouldn't be the problem. (either way, it should last 1.5 hours) I plugged it in, and in about 5 minutes it was showing 50%. I am not really sure if this is a hardware problem or a software problem. (I am restoring now) Has anyone else had any issues like this? Does anyone have any advice?
