I don't seem to be having any problems, I have been using it a ton for web surfing, email, texting, taking pictures, video, etc. I have only charged it once since I got it around 3pm yesterday, and took it off the charger around 5pm. It is now about noon here the next day, and I still have 30%. I guess after getting used to a G1, I am not that picky. Seems about on par with how my iphone 2g used to be. I imagine once I get over playing with the phone, it will probably last a couple days with no charge, though I am totally in the habit of doing things like plugging my phone in when I am in my car, when I sit at my computer, and when I am watching tv, that it really is no big deal to me. And when I travel, I usually always have my laptop, so I always have a power source I can mooch off if need be.
