my battery life is good.
i unplugged it at 10:45AM and now at 9:15PM it's at 54% with moderate usage. i played music for a little over an hour, played a flash video over 3G for about 20 minutes, surfed the web for about 5-10 minutes, sent and received a couple of texts, showed the phone to a few people at my job, and had a quick 2 minute phone call.
i have gmail sync on, weather to sync every hour, Feedr and the news and weather app to update every 3 or 4 hours, facebook every 2 hours. i have the screen on auto brightness with a 30 second screen timeout. nothing really to battery conserving.
