I have a rather strange problem. I bought a Logitech Bluetooth mouse some time
ago. It works very well in Ubuntu and I never had any usage problems.

The strange thing is though, that the batteries that are inside the mouse
drain extremely quickly. I compared the time it takes the mouse to drain a set
full batteries to my flatmate's who uses the exact same mouse with Mac OS X.
It turns out that my batteries drain about four times as quickly as his.

how quickly is 'extremely quickly' ?

I suspect however that Bluez is somehow talking with the device in such a way
the mouse doesn't sleep as quickly as when Mac OS X talks to it. Could this
somehow be the case? If so, what could I do to help solve this with Bluez?

what are the link policy settings for that link? (see hcitool(1))

for instance, if I don't enable SNIFF mode then my [Apple] keyboard drains
the batteries in a few days, vs many weeks otherwise ..
