    I installed a fresh copy of Snow Leopard last night on my Macbook Pro (Late 2007, 2.2) and the battery life seems to be much better than under Leopard. Has anyone else noticed this?

    Can you give some figures, and also your specs for your Mac you're using? (You'll want year, Macbook type, RAM, and CPu, and also probably the number of cycles the battery's had :) )

    Unfortunately, I haven't benchmarked battery life under Leopard. I am on track to get 4 hours on this battery, whereas under Leopard I was not near that. I will try to collect detailed info.

    You really want to pay $500 a year for buggy OS builds with all the interesting bits stripped away? Unless you're a developer (and hence require day-one compatibility with the new OS and need to plan to take advantage of new features) or an idiot, you wouldn't pay it.

    Very interesting. I'd have thought that OpenCL would increase GPU usage, therefore decreasing battery life. Maybe they made optimizations elsewhere or OpenCL is used very lightly on notebooks.

    Wow! Snowleopard already gives Faster start-ups and shutdowns, 6 Gig less space consumption, 64-bit support, text expanding, screen recording and some UI enhancements.

    If the battery life improves, hats off! I will be one of the first ones to get the upgrade :)

    My experience has actually been the opposite. I am getting less battery life in Snow Leopard. But I think the difference is that in Leopard I was using Coolbook which meant the fans ran a lot less. I'm guessing when Coolbook is released for Snow Leopard the battery life will be comparable.

    I've had quite the opposite. My battery life has been terrible since I installed Snow Leopard. It was a clean install after Leopard.

    Any ideas?

    I've had the opposite on my newish unibody mbp (15 inch). I would get anywhere from 5-7 hours normally in leopard; now i get 3-4. :(

    Mine is the same, terrible battery life and my computer is running hotter. I have checked Activity monitor and there is nothing out of the ordinary running. Any ideas anyone?

    Well one thing would be if you are running in 64-bit then your life will drop. That takes a lot of power to run. I haven't actually tried but also make sure you aren't using the 9600 graphics (if possible) when not plugged up...

    Wouldn't running in 64-bit make the OS more efficient, therefore having less/shorter CPU processes? I don't see how 64-bit would shorten battery life.

    I could be wrong, but I'm under the impression that my macbook pro 13 inch 2009 runs a lot cooler and runs longer on 64 bits.

    Strange, My macbook 4,1 seems to get about 20 minutes more battery life than in leopard.

    Running usual apps and having wireless on constantly.

    This is likely untrue. It'll lead to a bit more bus and cache traffic from larger pointers, but the newer objc runtime and extra registers should balance that out (or more likely more than balance it out).

    My MBP seems to get much battery life too. On Leopard, my battery used to give me around 1:50 (my battery is around a year old and I've not been treating it nicely enough). And in Snow Leopard, I get 2:30 easily. I was really happy about that.
