No Internal Design Changes Found in New MacBook Air Disassembly
Just one day after the latest MacBook Air model debuted, images of the 11-inch version with its bottom cover removed were released on the internet. These pictures reveal that no changes were made to the laptopís interior layout when compared to the 2012 model. When Appleís senior vice president of worldwide marketing Phil Schiller announced the newest iterations of the MacBook Air on Monday at the WWDC keynote, the first feature he noted was the extended battery life on the device.
According to Schiller, the 11-inch model will go from an advertised 5 hours of battery life to 9 hours, while the latest 13-inch version lasts up to 12 hours, up from 7 hours. It appears the energy savings are fully attributed to the switch to Intelís power-sipping Haswell ULT CPU and corresponding OS tweaks.
From what is noticed by the superficial teardown provided by Other World Computing, the 11-inch model remains largely untouched with a battery and component layout identical to that of last yearís iteration. The lack of change is to be expected as Appleís product page notes no change to the 35-watt-hour battery, which in the case of the 11-inch MacBook Air is a six-cell design. The recently announced 13-inch version hasnít been torn down yet but the internals are also likely similar to last yearís model, which featured a four-cell layout thanks to the additional space allowed by a larger chassis.
Also seen in the images is the new solid state drive that Apple is using, which features a PCIe controller for faster transfer speeds. It was recently noted that Intelís Haswell processor provides the most gains in terms of battery life while the PCIe flash memory solution brings major improvements in terms of speed.
