17 hours at 73% is a bit extreme, but so is 2% per minute drain.
I think I can represent a fairly average user. I usually check email, weather and a little reddit during my morning routine. BT is always on and connects to my car while I drive to work for about 30 minutes. I average about 2 or 3 long phone calls a day on my phone. Some text messaging throughout the day and some short internet sessions on my phone while at work. Plus a few minutes here or there for Draw Something. I stream Google Music every day on my way home for about 30 minutes. Once at home my usage varies depending on what I do for the evening. But so far I usually find I have about 50% battery life when going to bed. I actually made it through Friday and Saturday on a single charge.
So I would say that this phone has above average battery life for an android device. It isn't stellar, but it isn't bad either. My Infuse could eek out about the same life with less use. My N1 never made it even close to this length. My buddy's MyTouch 4g can't usually make it a full 24 hours.
