While the new MacBook Pro’s retina display, light weight, and thin format factor were all show stoppers, the notebook’s battery is also a major feature and feat of engineering. Apple claims that despite powering all those pixels, the new MacBook Pro with Retina display has a battery will last for seven hours on a single charge and offer a full month of standby power. Unsurprisingly, much of the its internal space is devoted to the mammoth battery required for that feat.
The new MacBook Pro with Retina display isn’t the first Apple device to sport a massive built-in battery. The new iPad also sports one and the MacBook Air line has had most of its internal space devoted to its battery for years. Each new mega-battery from Apple represents an advance of battery technology that few other companies could deliver.
