If you have an iPod, iPhone, or iPad, you’re already taking advantage of all that flash storage has to offer: reliability, speed, and efficiency. So the decision to use flash storage in an ultracompact notebook like MacBook Air makes perfect sense. Flash allows you to access data quickly, and it gives MacBook Air the astonishing ability to remain in standby mode for up to 30 days.¹ Which means your MacBook Air snaps to in an instant, whether you open it tomorrow, next week, or next month.
Since space-saving flash storage leaves room for a bigger battery, you can devote more time to the things you enjoy most. Things like browsing the web, editing photos, and watching videos. Get up to 5 hours of battery life on a single charge on the 11-inch model and up to 7 hours on the 13-inch model. Put MacBook Air to sleep, and it enters standby mode to conserve battery life for up to 30 days.¹ When you come back to your MacBook Air and open it up, it’s on in an instant. So you’re free to go off the grid knowing you’re still on a charge.
