Your battery graph still works while you are running Android? Interesting; I wonder how it does that. The battery usage is flaky at this point. I usually have charge my battery with an external charger. With this, I had to charge with the N900 itself until it went green. Then when I booted Nitdroid all was well. So I could MOSTLY till charge with the external charger -- it only seemed to care if it was topped up with the N900 itself. Edit: Oh, you must be saying that Nitdroid shows half your battery is used up. That is not saying that Nitdroid is consuming half your power, as you seemed to be stating. As I said, it's flaky.
