Haswell MacBook Air Battery Life Is Pretty Insane


With double the battery life of the strongest current Windows 8 competition, the Apple MacBook Air 13-inch (Mid 2013) adds epic untethered usability to a highly portable system. While systems like the Acer Aspire S7-191-6640 and Vizio CT14-A4 start to approach the MacBook Air’s portability, none can approach that level of work utility away from a power outlet.

PCMag managed to get fifteen hours of use out of the machine in their testing. It should be noted though, that the battery life comes at the cost of raw compute performance; the Air clocks in slightly lower than other ultrabooks. However, the Air isn’t targeted at a user who is looking for a maxed out spec sheet. Since the first iteration of the Air, Apple has ruthlessly prioritised certain aspects of this laptop over others. With this latest generation, this selectivity is simply more pronounced, with an obvious sacrifice of CPU performance for battery life.
