    http://www.engadget.com/2009/11/12/windows-7-bested-by-xp-in-netbook-battery-life-tests/

    Engadget reported on Thursday about three different sets of tests which found substantial reductions in netbook battery life (including on netbooks that shipped with Win7) using Windows 7 instead of XP, even when all the Aero features are turned off.

    Interestingly the conclusion is similar for the Asus computer that was shipped with Win7 and the MBP that doesn't yet have official Win7 bootcamp drivers.

    Interesting. On my 1008ha I find the deficit to be marginal at best. I use AeroFoil to turn off Aero on battery and I optimize CPU through SHE 2.09. I also disable the webcam on battery. I find Windows 7 to be about 10-15 minutes less (on about 5hrs 30min total) than XP which is well worth the price to me.

    Yeah, it seems to me with all the tuning and efficiency options it ought to be able to do even better, but if I had one of the 11-hour netbooks, I'd live with losing 15-20 minutes....

    To be honest, I don't even notice. My 3 hour battery life on my netbook is still better then the 1.5 hours that XP gives me in bootcamp.

    You have an MBP that gets 1.5 hours of battery life? :eek:

    It makes a difference to me for two reasons -- first, for watching video on trips by air, where every moment of extra battery power counts, and second, because modern notebooks just don't conserve power while sleeping as well as they used to (although with non-SSD netbooks, hibernation is an option).
