The battery at 6PM is at 50%, so from 100% Charge, pulled plug at Midnight to 8 AM, it maintained 100%, and has dropped to 50% over 10 hours of moderate 3G usage- Email typing, reading, RSS, browsing, phone calls, texts, and blogging. I will say this... On 3G, I am getting full bars out where I live, never got that from any other phone. So that fact helps battery life too. Will answer questions and post any new revelations. I talk about the phone more in my comparison thread to Charge and Incredible 2.
