Mine has been very good, probably around 30-40 percent better on power than my N900. Seems to use less power even when just used as a phone. I still have my N900 and miss having a real Linux box in my pocket but I have to admit the HTC hardware is nice and for my ordinary daily needs Android 2.2 is getting the job done. That said, if Meego ever reaches a reasonable level of maturity and availabily on good, suitable hardware, I'd drop Android again in a heartbeat.
