Hi Andrew, I am starting to suspect that one thing that perhaps could be a huge battery eater is the 3g connection. I'm not sure if this is related to PR1.2 at all (probably not), but at my workplace I notice that the 3g signal is kind of weak and battery drain goes quick during working hours but slows down to a minimum when I'm elsewhere, so I suspect that the device increase the signal strength and of course eat more battery. The question is whether the radio module/software has some glitches or is in the need for optimization. Maybe I need some more info about other phones and with the same mobile network in the area to see if the N900 stands out with the signal strength. 1-2 hours though sound a little bit too much to me. I get like 7-8 hours to reach like 15-20% of battery left at the office place (but that's a little bit high too if you ask me).
