Welcome to a laptop battery specialist
of the Apple Laptop Battery
A big part of evaluating laptops is battery life. Since the tests take so long, our reviews of the new MacBook, 13-inch MacBook Air, and 13-inch Retina MacBook Pro posted without hard data for battery life (the MacBook review had Jason Snell’s observations while working day to day).
Battery life is one of the most common concerns by readers when Apple releases new laptops. It’s an important data point; no one wants to be stuck with a dry battery with like Apple M8244 Battery, Apple A1079 Battery, Apple A1078 Battery, Apple A1148 Battery, Apple M6091 Battery, Apple M8956 Battery, Apple A1008 Battery, Apple A1061 Battery, Apple A1060 Battery, Apple A1022 Battery, Toshiba PA3166U-1BRS Battery, Toshiba PA3331U-1BRS Battery, and Apple uses batteries that are not user replaceable.
I ran two different battery tests on the new MacBook, 13-inch MacBook Air, and 13-inch Retina MacBook Pro. The first test I ran produced results that jibe with Apple’s specification. The second test produced results that fell quite short, but there are a lot of factors that influence how long a battery can last.
In case you are interested, the three laptops had the following settings:
