I have a 2.1 steup and receiver. I plug my ipod into my 360 to play music through the speakers. I havent took the ipod from the 360 in weeks. I play music everyday, and the ipod charges every time I play music. So its been fully charged for months, and continues to charge every day. I recently saw someone say that doing this hurts it and I HAVE to drain the ipods battery really low once a month or something stupid like that. Does leaving my ipod on my 360 and playing music hurt it?
