A properly maintained iPod battery is designed to retain up to 80% of its original capacity at 400 full charge and discharge cycles. You may choose to replace your battery when it no longer holds sufficient charge to meet your needs.
- Make an appointment at the Genius Bar of an Apple store. I have heard that if capacity goes to 1/2 original capacity during warranty period Apple will exchange your iPod.
