During our testing, the new iPod touch ran a looping playlist of test 640x480 videos for 7 hours and 52 minutes before expiring, a two-hour boost over the prior version that put this model in the same league as last years iPhone 3G and the 120GB iPod classic for video playbackwith Wi-Fi off. By comparison, when we ran an audio runtime test with Wi-Fi onthe way Apple measures itthe new touch ran for 30 hours and 20 minutes before expiring, just surpassing the companys 30-hour promise. Oddly, we found that Apple has changed its performance estimate for the second-generation iPod touch to claim the same 30 hours. In any case, the device does match or outperform the companys claims when used purely for media playback purposes, and when Wi-Fi was turned off, audio run time jumped by 2 hours and 4 minutes to 32 hours, 24 minutes.
