I'm a student that's always transfering things on and off of the ipod. When I connect the ipod via firewire to access the files, the battery begins to charge. When I'm finished using the ipod I disconnect it from the computer. Sometimes the ipod is charging for 2 mins and sometimes it can be charging for 1 hr, depending on what I need the ipod for. I was wondering does this kill the battery life? I bought my 3G ipod 10gig, 10 months ago and the battery life now isn't as close as it was before. I drain out the battery before I charge each time. Does anyone else have this problem? Any help will be much appreciated. Thanks.
