Fifth-generation Intel Core processors in MacBook Air give you more time to do more things. Add that to an array of other smart and efficient features, and you have an incredible amount of power in your hands. While carrying next to nothing. Thanks to compact all-flash storage in MacBook Air, there's plenty of room for a big battery. Working together with the power-efficient fifth-generation Intel Core architecture, this battery can post some impressive numbers. The 11-inch model gets up to 9 hours of battery life on a single charge and the 13-inch model gets up to 12 hours. That gives you all-day power for surfing the web or watching iTunes movies. Put MacBook Air to sleep for more than 3 hours, and it enters standby mode to conserve battery life for up to 30 days. And if you enable Power Nap, you'll continue to receive new email and calendar invitations while your computer is asleep. MacBook Air is powered by fifth-generation Intel Core i5 and i7 processors. This ultra-efficient architecture was designed to use less power and still deliver high performance. Which means not only can you do whatever you want - you can keep doing it for longer than before. In addition, the Intel HD Graphics 6000 processor offers advanced performance you'll especially notice with games and other graphics-intensive tasks. MacBook Air supports ultrafast 802.11ac Wi-Fi. When connected to an 802.11ac base station - including AirPort Extreme and AirPort Time Capsule - wireless performance is up to 3x faster than 802.11n Wi-Fi. And your Wi-Fi range improves as well. With Bluetooth technology, you can connect MacBook Air to Bluetooth-enabled devices like speakers and headphones. Even without all the wires, you're totally connected.
