CNET Labs Completes Zune 80 Battery Test
CNET labs finished their Zune 80 battery life test. The good news is the battery was tested and is a significant increase over the Zune 30. Microsoft advertises that the Zune 80 has a bettery life of 30 hours, but the CNET test resulted in a 22 hour battery life (with WIFI turned off) and 18.5 hours (WIFI turned on). The good news is this is an improvement from the Zune 30s 13 hour life, but well short of the iPod Classic 80 GB battery life of 45 hours (no WIFI capability). This test was with playing audio only so expect less battery life with video.
There are obvious reasons for a shorter battery life compared to the iPod. For one the Zune screen is much larger than the iPod classic. With a bigger screen and similar resolution you must expect a shorter battery life, especially with video (4 hours). I would also expect less room for battery as the Zune has WIFI and radio capability while the iPod does not.
If you have done a test on the Zune 80 battery please post a comment!



Most movies made today need a decoder to copy the movies to your PC. My question is do I need to buy a decoder first before I buy a converter for my Zune? Or does the converter you buy have it all?
My Zune 80 battery doesn’t last anywhere close to 22 hours. Actually I don’t think i’ve got it to last over 10 hours. I never have the wifi on, backlight is set to 3 secs, and volume never exceeds #5 when listening to music. I watched a few videos, but neither exceeded 5 minutes. Just today the battery indicator read half full and it all of a sudden died on me. I hope I didn’t get a crappy unit.
Actually I have the exact same problem. I’ve been trying to research this and I haven’t found anything that says different. I was guessing I had a crappy unit as well, but now I know you have the same problem. I really think they are sayin this just to make sells and being paid to say it has a better battery life. I’ve been trying to find an extended battery but so far I’ve had no luck. If you find one let me know and I’ll do the same, thanks.
Having the same problem with my battery life. I just got back from a drive from Virginia Beach to Long Island, NY. The trip was roughly 9 hours and I started with a full charge. By the time I got home, battery was almost completely dead. Volume did not exceed 6, no videos were played, and to be honest I didn’t even have the Zune on the entire trip. Either there are some defective units or this battery just completely sucks.
Short battery life for video too. I had wireless turned off, brightness at medium and I only got 1.25 hours playing an mp4 file before it went dead. That sucks!
