So did 10.8.2 improve battery life?

[zObsidian]

Hey, did you do an upgrade from Lion to Mountain Lion? Or a fresh install?

It's a new MacBook Air. It came with Mountain Lion pre-installed (10.8.1).

I got like 2 more hours when updated. So I'd say that I have some improvements

Does the mid-2012 air have better battery life? I don't get any of these stats this article shows here. I use to be around 6-7 hours when i got this with Lion but now ever since the new update to Mountain Lion and the 10.8.2 it's running around 5.5 hours max and that's with very low brightness, about 10%. Is this only me because i hear some other people getting better battery life.

Right now i'm sitting at 4 hours with 70% left and backlit off, 10% brightness on screen. That other 30% seems to disappear within 1 hour which i find a bit off.

EDIT: Anyone else use full screen on Safari? I like to use it because it's easier to switch but it seem to be hogging a lot of the battery.

I'm using mid-2012 air but I think the battery life gets a bit worse than it was before.

From 100% to 99% takes less time than it did before the last update :\

The battery life has NOT improved what so ever. Mid-2011 11" MBA.

There aren't any news on any fixes right?

A few days ago, I used Photoshop CS6 for half an hour to design a poster while
AirPort was turned off and the brightness was set to 7-8 bars. When I was done, I still had 9 hours and 4 minutes of battery life left

I am getting constant 7-8 hours of straight usage while browsing with clicktoflash and adblocker. I am satisfied with battery life. 2012 13.3 MacBook Air.

I think that the people who are not getting battery life improvements after doing a clean install of 10.8.2 either have a faulty battery or faulty hardware. I mean how is it possible that the rest of us are getting good battery life when we are doing the same method of 10.8.2 installation? Can't be software issue.....

The battery indicator in 10.8.2 is completely wrong. It reports around 4:52 from full charge but ends up lasting 7-8 hours. Usually gets stuck at 4:52 for around 1-1.5 hours.
