Not sure that I'm very pleased with the battery. This is with wifi off, bluetooth off, location services off and screen brightness around 25%. Usage time is mostly casual internet (no streaming or anything data intensive) with some twitter and a few emails and sms mixed in. Push and Fetch are both disabled. I totaled less than 10 minutes of actual calls. Apple rates the phone for 5 hours of 3G surfing and/or voice so I expected to get at least that amount of usage. My usage below comes out to 244 minutes with 10% battery remaining. That projects out to 271 minutes if I drain the battery to 0. Let's see your screenshots and a description of your usage.
