    I hope so, because I only get 3-4 hours web browsing on low brightness.

    It came out half an hour ago, jesus. Give it some time. As for now though, it definitely feels faster in terms of performance.

    Does Safari feel snappier I hear you ask? See for yourself ;)

    Seems to

    I have about 30-45 more minutes showing right now than I've ever seen before.

    So yes, at least initially.

    You only get 3-4 hours from light browsing on low brightness?

    I get ~6 hours on 9 bars of brightness watching ~45 minutes of video + web browsing + music playing.

    I haven't tested this new update yet. Downloading now :D, I'll post results once it's done.

    I'm also updating iPhoto. 1.14GB. Seriously. WTF?

    Uh...

    Do you have a Macbook Air?

    I traded screen size and battery life for portability. Still totally okay with it.

    The new update gave me exactly 7 hours of actual usage.

    It's estimating 4:40 from a full charge which is underwhelming but I'm sure it will re-evaluate and give me a better number soon-ish :I

    edit: says 8:10 now. yuppie! 6 bars of brightness.

    I'm not gonna do any tests other than using my computer normally, but I hope so. My brand new MBA dies way too quickly compared to my old 13" 2010 MBP.

    He probably has a 13 inch Air. I also get that regularly (if not more), but I don't use the screen as brightly as he does. Your 11 inch Air is expected to get shorter battery life than the 13 inch.

    I can't tell if 10.8.2 improved my battery life yet because it broke my battery meter :( It was showing 100% for 10 minutes and I thought "wow, this is much better" then I checked Battery Health app and saw that it was actually around 96%. Now the battery meter is reading 88% and it is actually 83%. The actual life seems similar. It isn't terrible, I'm showing about 5:30 right now for web browsing at about 50% screen brightness.

    2012 Air

    Maybe a dumb question, but what "should" the battery life be for the 2012 Air 11"? Also, what has the battery life been for previous generations?

    Currently doing light use with screen at 50% on my 2012 13" MBA (word processing, online questions bank for an exam I'm studying for); 1.5h in with the screen never going dark, I'm at 79%. I think it's an improvement from before.

    Working at night with screen/keyboard at lowest brightness with bluetooth off but wifi on and a few programs open (safari, excel word). Just unplugged and have been using my MBA 2012 for a bit and the battery saying about 8 hours remaining :D. In a few weeks I should get a better estimate of the real life, but the Air has never read that high before for me!

    Hmmm, no noticeable difference I'm afraid on my 13" 2012 MBA.
    It certainly hasn't reduced it, I would say it's increased it, but running the battery down took about 10 minutes longer I'd say so not a considerable amount

    How many hours does your car drive on a full tank? Same question. Depends on what you are doing. Put screen on full brightness, attach an external DVD drive and compress movies with Handbrake, and at the same time charge your iPad, and the battery empties quickly. Less brightness and browsing MacRumors and the battery lasts a lot longer.

    I can't understand why people are trying to compare estimated battery life remaining. It's a pointless endeavour guys.

    I don't know about the battery life yet, haven't tested that enough, but the new update is deffiently a big improvement. Switching between desktops doesn't lag anymore (which occured to me since 10.8). Also turboboost works now under Windows with the 2012 i7. Very happy about that.

    I had no battery issues until 10.8.2. Now my battery life is shocking. 3.5 hours if i'm lucky (nothing intensive). 2010 MBP
