I have a 3G iPod. Runs great. Except one problem... Randomly, the iPod shuts off completely and drains its own batteries! I mean it shuts off so that the next time you press a button, the Apple logo pops up doing a complete startup. It doesn't matter if it's in its dock charging or if it's out in the wild. The battery would be litterally full at one moment, then the next moment you turn it on, most or all of the battery is discharged! It usually happens overnight about weekly. It's like its restarting itself or something. Any solutions or does this happen for the rest of you guys?
