Microsoft has finally posted the technical specifications of the Zune HD on the Microsoft Store. The device’s dimensions are 52.7 mm x 102.1 mm x 8.9 mm (w x h x d), with a weight of 2.6 ounces (74 grams). The Zune HD will ship with the following accessories: headphones, Zune Sync Cable, and three pairs of foam earpiece covers. Battery life is cited as up to 24 hours (wireless off) for music and up to four hours for video, but this seemed a little toward the low-end. We e-mailed Microsoft and got back much better numbers: up to 33 hours (wireless off) for music and up to 8.5 hours for video (charge time is three hours when connected to a PC and two hours with A/C adapter), with the following footnote:

1Music estimates based on 128 Kbps WMA files with length of 4 minutes each. Pictures transferred to Zune will be optimized for Zune screen size; video estimates based on 500 Kbps WMV files with 128 Kbps WMA audio tracks. 2Battery life was tested by Zune in August 2009 using preproduction hardware and device software. Battery tests are conducted with specific Zune units. Actual results may vary. Audio content used was WMA 128 Kbps. Video content used was 320×240 WMV9 500 Kbps total bit rate. Batteries have a limited number of charge cycles and may eventually hold less charge. Battery life and the number of charge cycles vary by use and settings.
