How long should an iPod battery last
iPod touch 4th generation
An iPod battery is supposed to last for 8 to 12 hours. Without being used, it can last up to one month when fully charged. You may find that your battery is empty before then, but that's normal.
oh for me it only takes 2 hours haha and the answer above me is sorta wrong because it all depends on how much u use it.
