What is the battery life of an ipod nano 4th generation suppose to be?
The batter LIFE, of an ipod nano 4th generation is for audio: 24 hours and for video: 4 hours of course these are variable on the brightness, and how often you actually use the buttons, for scrolling etc, because all this uses up battery. So i would say that 2 and a half hours wasn’t very long, no. But you can turn down brightness, or lock your ipod when playing music, so doesn’t use as much battery.
