My scud update. Moderate phone usage. Very limited internet usage (checked mapquest for directions a few times). Driving all day today with signal dropping from 3.5 down to nothing and back numerous times. I just hit around 60 hours of uptime, and my N900 just started making the 'help me I'm about to die' sound. I'm perfectly happy with 2 plus days without having to recharge. Once again this is with a single battery, not the dual-battery mod.
