    The battery life of my MacBook Pro is very bad using Windows. So I measured it with the stopwatch on my iPhone... Result: 1 hour 41 minutes :eek: (just surfing on the internet)

    I use the 2009 15" MacBook Pro with 3.06GHz. Battery cycle count is 103 and condition is normal...

    Is this still normal?

    It's because bootcamp doesn't take advantage of the power saving features present in OS X.

    Are you using Windows 7? If not, do so. Another thing is that Apple has prevented Windows from using the 9400M on your machine (I think that's what the 2009 model have). When you boot into Windows, you are using the much more power hungry 9600M, automatically giving you bad battery life.

    Apple could of course enable a setting in the boot camp preferences to chose video card at reboot but they haven't done so. No love for Windows users.
