Latest OS X 10.8.2 Developer Build Gives MacBooks Best Battery Life Since Snow Leopard

Everyone knows that the “upgrade” to OS X Mountain Lion severely reduced the battery life in Mac laptops by up to 38%. And while OS X 10.8.1 helped things some, the fix was still meager compared to the oceans of juice you comparatively got on the same machine running OS X Lion.

OS X 10.8.2, though? Much, much better. In fact, according to The Mac Observer, in the latest Build 12C35 of OS X 10.8.2, not only does the latest development version of Mountain Lion give users a bigger upgrade in battery life than OS X 10.8.0 or OS X 10.8.1, but their test system — a 2011 15-Inch MacBook Pro 2.0GHz i7 — now has more battery life than it did running OS X 10.6.8 Snow Leopard, the previous champ Mac operating system when it came to conserving juice.

In fact, while their test system lost 105.5 and 80.5 minutes of battery life compared to 10.6.8 in OS X 10.8.0 and OS X 10.8.1, respectively, it actually gained eight minutes against OS X 10.6.8 in OS X 10.8.2. Now those are some impressive results. Results I’m now off to test for myself.

    Thats good news as my mid2011 mba lost ca 40% w/10.8 and another ca. 5% w/10.8.1. Previously it was good for ca 5h.

    At this rate another update like those, and i’ll have the thinnest desktop ever.

    Any word when it will release to normal customers? Must be any moment now given that 10.7.1 is almost two weeks old.

    excuse me but the latest version of 10.8.2 is 12C43 not 12C35!

    About time… This was one of the main reasons I skipped Lion entirely on my production laptop and was sticking with Snow Leopard.
