You say you get 3-4 hours in Linux, but the benchmarks you link to claim easily 7 hours in OS X (though dramatically less if you max out the CPU).
Are you pretty much always at high CPU utilization, or is Ubuntu's power management of Mac hardware that poor?
- bergie 15y ago7 hours is for the 13" MBA. I have 11".
- rufo 15y agoAccording to AnandTech's tests [1] (the ones you linked to), the 13" gets over 11 hours in OS X - the 11" is just under 7. [1]: http://www.anandtech.com/show/3991/apples-2010-macbook-air-11-13inch-reviewed/9 http://www.anandtech.com/show/3991/apples-2010-macbook-air-1...
- zcid 15y agoI get only about 2.5 hours when running Arch Linux compared to almost double when I used to run OS X on my MBP 5,3. I rarely use my laptop unplugged though so it doesn't make a huge difference to me. I think a large part of the difference on my machine is that you are forced to use the 9600GT for video as opposed to the more efficient 9600M that is available in OS X.
- rufo 15y agoYeah, that's what I suspected - that's a huge deal to me.
- yardie 15y agoIt's probably better to say that OSX power management is better on Apple hardware than all the rest. I was getting about 40% less time when using Windows XP than when I was using OSX.
