I wish I had some idea what "normal" usage means, because I'd like to think I fall into that category, but I might be a "light" user by some standards.
Regardless, I was a day one adopter, and would say the battery life has been comparable to my Blackberry Curve, better than a D1.
I use my phone for business, so I receive a fair number of work related calls, I do a fair amount of email and texting, light internet browsing, and mainly only use weather, sports, TV, and fantasy football related applications. I unplug, on an average day, when I wake up (roughly 6AM) and don't recharge (on most days) until around 10/11PM (when I crash). No widgets to speak of, because I think (for the most part) they're useless, ugly, clutter, and I'm a neat design freak.
So far, so good. For me.
