I have a fairly new battery and noticed that once my N900 got down to "0% Battery" I was still able to actively use (playing games, browsing file system, but no calls) it for another 45 minutes. After 45 minutes I started charging it, but I wonder how much longer it would have lasted while reporting a "0% charge".

Does anyone have any thoughts or experiences?

it's probably uncalibrated. I had this couple of times. The actual charge is probably around 10-20%

I´ve had mine go on for 4 hours while connected to the network.

It just depends how far off calibration it is.

Is there a way to "calibrate" it?

My battery percentage is pretty unreliable too. It actually just went up from 25 to 29 percent (something that I've seen happen with other PDAs if you use them for a while and then put them away - the battery voltage seems to rise a bit). I guess there's a reason Nokia went with a simple 4-bar indicator.

I use a program called batterygraph.

You can also use a Queen Beecon Widget (or desktop command execution something something) with the battery % command.

BatteryGraph is a very useful tool.

Actually, the battery icon shows 9 levels of charge in 12.5% increments (not that it's accurate).

When your widget shows 0% probably it means 7% remaining.

N900 seems to raise low battery warning at about 10-15% remaining, and shuts down at 6% remaining. (Then people try force it to start, try to flash it, and whatever stupid things they come up with. draining the remaining 6% making it extremely difficult to charge again)
