32W means you get almost 1,5 hours. That's ridicolus. Maybe your scaling governor is not working, or battery is not calibrated.. Then you have a macbook pro so you may have that problem with ati drivers. > > >> It's also hotter when using linux.

On some macbooks pro only C1 and C2.

Maybe this is enough. > It's not. If I unload the module for bluetooth and the userspace bluetooth daemon.. the bluetooth act in some sort of emulation. My bluetooth mouse keeps working but it's seen as an USB mouse. It's cool, but drains power. Another thing I've seen is that linux is much faster pairing devices when they get in range, so i guess that bluetooth under linux polls for devices more often.
