I've been reading threads for an hour now, waiting until 9:00 so I can call Nokia.

My first N800 would not go into USB mode so I couldn't upgrade it; they replaced the device with no fuss.

I've been using these types of gadgets for many years - Palm Pilot, Pocket PC, Zaurus, etc. and I was thrilled at the battery life on the N800. I connect with WIFI at work and at home, and with bluetooth through my cell phone. When I'm not actively using it, I let the N800 go to sleep by itself. With 1-2 hours of web browsing, reading e-mail installing new software, etc. the battery would stay charged for two days or more.

Starting yesterday, it seems to hold a charge for less than 8 hours, even while sitting on the table in standby mode! further, I turned it off and left it overnight on the charger. It never got to the "Charged" indicator on the screen, but when I turned it on, the battery icon was at 100%.

I'm wondering (searched but haven't found) if there is a utility that will plot battery drain (ma) over time, or at least will give some sort of indication of the instantaneous %charge and current draw. That would be helpful in diagnosing battery problems.

Now it's 9:00 and I will call Nokia to see if I can get a replacement battery!
