battery life when using bluetooth

[mainstang]

what kind of battery life can i expect when using a bluetooth earpiece with my 8525. Does it have any kind of bluetooth powersave mode ie. put it in sleep mode and shuts off bluetooth, then when call comes threw it will automatically connect bluetooth.

thanks

I only notice about 1% per 1-2hours power drain with bluetooh on and connected.

depends on the rom tbh.
