Why not try it and see? This will be highly variable as phones bounce around on charge capacity even from one phone to the next or battery quality varies a lot too. Only folk new to this would think it would be repeatable from one phone to the next.
Which Galaxy Nexus model matters, what apps are installed and carrier configuration matters too.
Great question but it only serves as a launch point of what a mess you jumped into.

Hey guys, I was curious to know the battery consumption of bluetooth on a phone if I have it on all the time. Its for a project. essentially the connection will always be sending information to the phone, like 12+/- times a second? (something like that, could be more.....) I wanted to know, for on a regular phone like the Samsung Galaxy Nexus, how fast that battery life would be drained....
