I dont seem to have an issue with battery and I use my phone almost constantly. When quiet at work I'll spend a good few hours browsing over 3G, and then some more when I get home over wifi. Add to that about an hours worth of music traveling to and from work and an hr or so playing games. I have to charge it every night but I know that at times I have pretty heavy usage. I'm just waiting for PR1.2 to come out before I change my kernal and get better life from it.
