2:20am CST, I am starting the Video test on the Zune 30 and Zune 80 to test battery life. Microsoft claims up to 4 hours for each device.

Both devices are fully charged and have been on their cradles for more than 5 hours. The only video on each of the Zunes is Linkin Park, Live in Texas. I ripped this video from my DVD at 25 fps @ 320x240 using SPB Mobile DVD. This is a program I have been using at this resolution on my Pocket PCs and Phones.

Both Zunes have headphones plugged in. The volume is at 10 out of 20 and the brightness is set to high. Since I have only this one video file on the Zunes ( 1:15 Minute Concert ), I will check them on the hour and restart the movie each time.
