That is pretty close to what I'm experiencing as well. I had a chance to give it a workout over the last few days on a trip. I HAVE noticed however that battery life greatly depends upon the activity. Audio playback seems to go on forever, but some other activities are a bit more power hungry. That's always been the case but it seems to be more so with the iPT6. That could explain the wide discrepancy in battery life being reported.Battery life on my gold 32GB seems to be very good - down to around 50% with a fair amount of usage.
Oh, in another thread I was concerned about the speed of taking photos with the iPT6 vs iPT4. No worries, it is as fast as my iPT4. (I noticed serious lag on my iPhone 4 that I used as an iPod)
