I've had my N900 for a couple of weeks now, and since it's been running since then. Battery life hasn't been great, but I can survive through the day on a charge, so I charge overnight. That hasn't been a problem for the past few weeks, until yesterday. Yesterday I put my phone on the "silent" profile due to a meeting, and when I looked a few hours later, the device was dead. In battery-eye I see a straight line all the way from 8 AM when I disconnected the charger to battery depletion at 2 PM. I've charged the phone again, booted and all is fine again now. I've no special applications running on the background, haven't updated any of them for at least a week and didn't do anything special during the meeting I was in (the N900 sat in my pocket the entire day ). Weird, huh? I'll try to make a battery-eye screenshot to illustrate the difference.
