Bluetooth is very low power... chances are something else other than Bluetooth is causing the battery to drain - is the phone sluggish/unresponsive when connected to your N800? Perhaps a process is running on the phone which is consuming CPU cycles thus draining the battery.

I don't know, I always remember even having bluetooth enabled on my phone or paired with my headset caused it to eat battery more quickly than if it was just sitting around idle without bluetooth. Plus 2.5 and especially 3g connectiongs have a tendency to rape battery life.

The phone is going to consume more power with Bluetooth enabled than with Bluetooth disabled but on the whole Bluetooth is quite efficient and shouldn't make a dramatic difference which is what the OP is suggesting is happening.
3G for sure eats batteries for lunch.

How long would your phone battery last if you were to establish a voice call and not hang up? 3-4 hours?
To take the phone-to-carrier connection out of the loop, establish an OBEX (file transfer) Bluetooth connection between your N800 and phone and see if you observe the same rapid power drain on the phone.

I guess I'm curious if this happens to everyone.. if not then how can I start troubleshooting this issue?
