This is probably a late reply. I have had two HTC phones in a row. HTC hero & then the Inspire. HTC hero was kind of a landmark phone and I enjoyed my Inspire but my gosh, what a battery hog. I kept two extra batteries and quite often, had to use them or keep the phone on a charger. I think the sense OS is a real battery hog and tends to slow their phones down too. It just draws too much on system resources. And the nonremovable battery was definitely a deal breaker for me. I just got the galaxy S3 and right now at around noon, its still at 87%. (I'm not a heavy user particularly when I'm at work) With the same amount of use, my Inspire would be ayt 50% and a lot of times, way below 50% and I'd end up putting it on the charger to get through the rest of the day. That's my opinion.
