How much ACTUAL battery life do you get on a day to day usage for video and/or audio for a 30GB and an 80GB (as in your personal experience)?

I'm looking to buy one for the extra battery life, but is it a substantial increase?

The advertised battery lives of iPods have (amazingly) tended to hold true for every iPod I've purchased. If it says it'll last 15 hours, it lasts very close to 15 hours for me. This is including shuffling about and having the backlight on whenever I tocuh the controls etc.

Dunno anything about video, though.

The current advertised battery lives for the 30 and 80GB iPods with video are 14 hours and 20 hours for audio playback, and 3.5 and 5.5 hours for video, respectively.

I've heard that the 80Gb is able to last up to around 22 hours.
