If u have an iPod then help me out. It seems that when i charged the iPod to the full extent and then i play it for like maybe 1.5 hrs and then turn it off and leave it off for 2.5 days it doesn't have any batteries left on the third day. and i know it hasn't been on cause i have the hold switch over. should i bring it back? its been less than 30 days since i bought it.
