When Apple's senior vice president of worldwide marketing Phil Schiller announced the newest iterations of the MacBook Air on Monday at WWDC, the first feature he noted was the thin-and-light's extended battery life.
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 can be fully attributed to the switch to Intel's power-sipping Haswell ULT CPU and corresponding OS tweaks.
From what can be gleaned by the superficial teardown, provided by Other World Computing, the 11-inch model has gone largely untouched, with a battery and component layout identical to last year's version.
The lack of change is to be expected as Apple's 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 has not yet been torn down, though its internals are likely similar to last year's 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 Apple is using, which features a PCIe controller for faster transfer speeds.

A report earlier on Tuesday noted that Intel's Haswell processor provides the most gains in terms of battery life, while the PCIe flash memory solution brings major improvements in speed.
