Poor battery life? My Magic Mouse would last 3 weeks of constant use with NiMH batteries on average.

However, this was only the case after I applied the software update for my aluminum bluetooth keyboard. The first few weeks with the mouse would get me only a few days worth of use, at best.

Maybe there's another bluetooth device nearby that's causing your Magic Mouse to work too hard, and suck up too much juice?

(Note: I don't use my Magic Mouse anymore because I've since fallen in love with the Magic Trackpad, which has survived even the most precise work with Photoshop for mocking up pixel-accurate UIs.)

Interest and thanks - maybe I have something going on there, I'll investigate.

I'm also comparing it to my old bluetooth mouse (a small laptop mouse by MS), and I only changed the AAA's in that maybe twice a year. Seems odd to me that a device running 2 AA's would need replacing twice as often.

I think I have the same mouse - GREAT device.

3 weeks with NiMH batteries isn't a good counterexample.

I use a Microsoft bluetooth mouse (the best bluetooth mouse I have ever found) and the batteries last about a few months with heavy daily use. It takes 2 AAA batteries.
