I think there's a bit of a quality control issue, or perhaps early batteries had problems. I have two G1s...a standard issue that arrived on release day, and a developer edition that I just got a few weeks ago. The former doesn't last a whole day of moderate usage with 3G enabled (but lasts about 1.5 days of moderate usage with 3G disabled). The latter easily lasts all day with 3G enabled. I charge every night, and I've never found it to give out by the end of day on days when I remember to charge it (and when I have forgotten to charge it, I've been pleased by how fast it'll charge up).

I have no complaints at all about battery life on the newer phone. The older one was disappointing, and I was afraid I was stuck with something that would never really be great.

Someone else suggested a "break in" period, but my older phone never got better after extensive use. The new phone was good from day one.
