I can easily say this is the best battery I've ever had in any smartphone I've owned, I've had a lot of them too, iPhone 3G, Nokia N97, 4 HTC's (Apache, Touch, TyTn 2, Touch Pro), Moto Q and a LG Voyager. The only ones that could compete was the N97, and maybe the iPhone 3G. I can use Google Navigation for 2 1/2 hours, 15 minutes of camera/video usage, heavy Gtalk texting, 2 episodes of 30 Rock (in 720), over a hour of web browsing, and like 8 calls. All of that leaves me with around 10-20% battery life coming from a full charge. I never conditioned the battery or any of that stuff because you DON't NEED to with lithium ion's, and I charge it whenever I am around my Media dock no matter what % it has left. If your getting bad battery life then you should definitely get a replacement or check out if any apps are sucking your battery. Also don't have your screen set to 100% brightness, I have found that 20-40% is plenty depending on what lighting conditions your in. Don't use auto brightness either.
