…and the world breathes a sigh of despair. Were you looking to scoop up a couple of Microsoft Zune 80s for your nephews, nieces, and gardner’s during the holiday season? If battery life is important to you, then you might want to think twice. CNET has just published the results of their recent battery tests, and the Zune 80 isn’t looking too good in the face of some stiff competition. According to CNET, the Zune 80 was only able to swing 22 hours of audio playback without Wi-Fi enabled. Turn on that wireless function and you’re looking at roughly 18.5 hours of playback. That’s great, but the 80GB version of the new iPod Classic was able to play for a staggering 45 hours before calling it quits. To be fair, the Zune does have a significantly larger screen than the iPod Classic, but is it worth a runtime that’s half as good?
