    The first reviews of the 2013 MacBook Air models are beginning to come out and, aside from new CPUs and a new SSD architecture, the biggest new feature is a dramatic increase in claimed battery life.

    Apple has increased the battery capacity of the 13" MacBook Air from a 7.3V 6700mAh unit to a 7.6V 7150mAh battery. As a result, the claimed battery life of the 13" model has increased from 7 to 12 hours. In its review, Engadget found the 13" MBA achieved 12 hours and 51 minutes on a charge under their standard battery test.


    Laptop Magazine's test unit achieved 10 hours and 53 minutes on a home Wi-Fi connection suggesting that, while mileage may vary, Apple's claims appear to be largely legitimate.

    A review from Forbes found that the battery life would be somewhere between 8 and 9 hours under more strenuous use conditions. Competing 13" notebooks don't come close to reaching 12 hours of battery life without external batteries.

    Apple says OS X Mavericks, when its released this fall, will include a number of battery-saving software features which could push the battery life of the new Air even further.

    Other notes from the review confirm previous reports of significant increases in flash storage read/write. Engadget reported similar numbers for reads and writes to the new PCIe-based SSDs, while also saying boot time has decreased to 12 seconds from 18 seconds on the 2012 models.

    Reviews also indicated substantial increases in both CPU and graphics performance on both benchmarks and real world tests. Laptop Magazine found the 13" MacBook Air returned 44.6 fps in a World of Warcraft test on 'good' settings, comparing favorably to similar Windows machines that returned between 30 and 33 fps in a similar setup.

    I only hope Apple seeks similar battery performance improvements for the iPhone line.

    This is actually quite typical of Apple "on its good days." With the iPhone 5, it's making a fantastically smooth UI on comparatively lower power than competing Android handsets.

    With the 2013 MacBook Air, it's great to see a focus on what most users care about: battery life! All modern Apple laptops are more than fast enough, so to have this kind of battery life is just fabulous.

    I PRAY we see a similar thing happen with the new iPhones this year. I'd love doubled battery life, somehow...

    Make it happen!

    Yes, it would be about time

    Kind of wish I waited to get this instead of MBP

    "Similar Windows machines" that were using Intel HD 4000, probably.

    Those reviews really make you believe that GPUs are miraculous on Apple machines, which is a huge BS.

    It would be nice if this news post touched on the fact that multiple reviews are griping about the fact that Macbook Air development has largely stagnated; in addition to the aforementioned positives.

    I've been waiting and waiting (okay, exaggerating, but..) for the Haswell 13in rMBP to land, but this darn new MBA sure is impressive! Beats the heck out of my 2011 MBA, that's for sure.

    Good job Apple (and Intel!) :cool:

    Looks like Haswell and Apple are the perfect combination, and to think it can only get better with Mavericks...

    Looking good! :eek:

    If Apple could improve battery life that much on the iPhones, they will do it as soon as they can. However, you can't really compare what Apple does with the iPhones versus the MacBook Airs with the new Haswell processors. The technology isn't fully there yet for iPhones.

    Awesome! Might be time to sell the 2011 13" MBA and upgrade :)

    So in other words, other than the things that have changed, nothing has changed.

    Yes, it's certainly a shame that MacRumors didn't explain that concept to us.

    So funny to read negative responses to the positive test results.

    iShould™ say that Haswell cores have up to 2x faster video decoders (H.264, MPEG-2, VC-1). That means they need less power.

    Still waiting to hear about non-synthetic performance improvements and battery life of the i7 upgrade.

    Damn it. This sucks.

    Now I WILL have to buy my wife one.

    That we know of. The technology IS there when it's available, and nothing surprises me these days..

    Looks like the perfect time for me to upgrade my air. The iPhone desperately needs this battery boost.

    Me too! I'm really hoping to see some battery life increases in the rMBP, but I also would like a quad core processor and Iris Pro graphics... We'll just have to wait and see what Apple decides for us.

    I would definitely sacrifice a speed increase on my iPhone for greater battery life. It's fast enough already.

    very tempting indeed

    but for all the reading and writing I do, the retina will be much better for me. The rMBP screens are the only retina screen where I noticed a huge difference.

    I will wait and see what the rMBP refresh is like (battery life and screen).

    This is great to hear. If I didn't need a better screen, I'd order one asap.

    Haswell + MBA + Mavericks = 12+ hours

    Haswell + MBP + Mavericks =

    we need details
    thank you :apple: we need it like hmmmm this fall ;)

    Trust me when I tell you that Apple is working on the best battery life for all its products. It is, however, limited by the laws of physics and the current state of technology.

    Someone please tell me when they think the next MBPr refresh will be. Then take my money.
