IFixit new MacBook Air Dismantling-super endurance, greater integration of batteries

In addition to IOS7, Apple's MacBook Air is one of the highlights of this year's WWDC. The 13-inch Air was raised to 12 hours from its original 7-hour endurance. Although compared to the previous generation does not have a big upgrade, but this 12-hour long endurance still let many people have the desire to buy ...

What is the reason for such a big upgrade, let's take a look at the foreign site IFixit to 13-inch MacBook Air demolition Bar.

First look at the MacBook Air configuration that's about to be dismantled

4GB LPDDR3 memory, optional 8GB

13.3-inch 1440x900 resolution, 128ppi

802.11ac Wi-Fi

Double microphone

In the appearance of the new Air and the previous generation basically the same, even models are also A1466, so want to install force are not, just as the iphone. On the right side of the Air as well as the previous generation, there are SD slots, USB3.0 and lightning connectors. The left side of the Air is a little bit different and becomes two microphones.

This step is relatively simple, with a screwdriver to the Air behind the screws unscrew can be seen inside.

The next picture on the left is the 2012 old version of Air, the right is the 2013 new version of air, by dismantling we can more clearly know the new and old two what is the difference.

In fact, the performance of the new air SSD hard disk speed also increased a lot, said than the previous generation has a 45% upgrade, and according to other foreign media testing, the new air SSD read and write speed reached more than 700 MB per second. The original SSD interface is also replaced by SATA PCIe, but also replaced by the Samsung brand, in volume is also smaller than the previous generation.

The next thing to disassemble is the newly designed AirPort network card, which can provide 802.11ac Wi-Fi. This network card uses Bo Tong's BCM4360, supports 5GHZ, the speed reaches the 1.3Gbps, simultaneously also supports the Bluetooth 4.0. There is also a block Skyworks SE5516 dual-frequency 802.11 a/b/g/n/ac WLAN module on this board.

In addition to the Speaker connector line is different, basically with the previous year version is not much different.

The I/O interface is basically the same as the old version, except that it no longer provides an interface for isight. There is also a 4208-crz Cirrus chip next to the headphone connector on this board.
