i could tell you right now, since that’s the exact ipod i have. i only listen to my ipod really in total a few minutes a day, tops an hour. it lasts a week or so, maybe more of doing that.
the backlight kills the battery more than listening to music does, it’s pretty lame. that’s why i set the backlight to 2 seconds only rather then 10… at 10 my ipod died in like 24 hours.
