Ryan Rea (Volvoshine) is doing a mini interview with one question a day to his source. The first question was:

Ryan Rea what kind of battery life are we looking at?

TK it should be roughly 5X more then the current iPod touch

The current iPod Touch is rated for 36 hour of audio and 6 hours of video. So if this is true you will be seeing 180 hours of audio on the Zune HD and about 30 hours of video. This translates into 7 and a half days of listening audio and 1 and a quater days watching video.

If this turns out true that would be very impressive indeed…
