iFixit tears down new 13-inch MacBook Air, finds secrets behind speedy SSD, 802.11ac Wifi and long battery life

We know a few things that Apple has included in the new MacBook Air lineup launched at WWDC yesterday– fourth-gen Intel Haswell chips, faster 802.11ac, 45{813a954d5e225a1509f22204ece89c855080ce25555f20805f61bed63cbfde3b} faster flash storage, dual microphones– but there could be a few other tweaks hiding inside that Apple didn’t announce live on stage. To get a better look inside, the folks over at iFixit have decided to give the 13-inch model its ritual teardown treatment.

Inside iFixit found a slightly larger battery, which on top of the new Haswell chip likely contributes to the increased, up to 12-hour battery life in the new MacBook Airs. The new model has a 7.6 V, 7150 mAh battery compared to the 7.3 V, 6700 mAh inside the previous generation.
