I have started a battery test tonight on the Zune 30 with 2.2 firmware, the Zune 80, the 8gb flash Zune, the iPod Nano Fatty, and the iPod Classic 80gb.

Update 1 - 10:45am CST, 8 1/2 hours in and none of them are even 1/2 life yet.

Update 2 - 2pm CST, 12 hours in. Zune 30 almost dead. All the others 1/2 life or slightly under

Update 3 - 2:45pm CST, Zune 30 dies. 12 hours 45 minutes.

Update 4 - Sad news at 8pm CST, Zune 8gb Flash dies. 18 hours. Zune 80 ~20%, iPod Classic ~33%, and iPod Nano ~25%. Not looking good for the Zune crowd.

Update 5 - Bad new Zune Fans... Zune 80 died at 10:20pm CST. That is less than 24 hours. 20 hours and 20 minutes. The iPods, both of them are still going. I will let them finish out before I post final numbers. Of course, this is just one test, but I am not happy.

Update 6 - iPod Nano dies at 2:25 am, 24 hours and 20 minutes. iPod Classic dies at 7:15 am, 31 hours and 15 minutes.

I am going to retest the Zunes with the same test later today. I realized that I had WiFi enabled on all of them.

All within a 2 minute period, I powered them all on after fresh full charges. I have the earbuds that go with the player (except I have ultimate ears on the Zune 30) plugged in to them. I am going to run them all until they quit. All the players are on shuffle all songs repeat mode.

This should be a fun real life test. Not very technical, but fun and true.

Company Announced Battery Times are Zune 30 - up to 14 hours, Zune 4/8 - up to 24 hours, Zune 80 up to 30 hours, iPod Classic 80gb - Up to 30 hours, and iPod Nano Up to 24 hours.
