Some people write about 20-40 hours of battery-life, i personally never could squeez more than 12-16 hours out of mine. Using 2G only, Juice Defender etc. I'm now on hei's Nova HD Plus RC9-18. This gives me about 18-20 hours of avarage use.
There could be something in that. I've just picked up an EVO 3D, and people complain about the terrible battery life. I'm currently on about 1 day 13 hours, and I've being trying to drain the battery lol. Somewhere between 20 to 25% left on it at present. My O2X has been pretty good as well :)
If I go to my office, I know battery life will be bad, as the signal is VERY bad, and is cut out about 80% of the time (it's continually on/off).. so wastes a lot of battery juice.
