Everything I loved about the last iteration of the Air holds true
here as well. The battery life is excellent. Apple says the
13-inch model should last 7 hours during regular web usage, I’ve
been seeing just shy of that after heavy usage. (The 11-inch model
is said to get the same 5-hour battery life as the previous
iteration.) Thanks to the Flash storage drive, the machine boots
up in roughly 12 seconds. And it awakens from sleep instantly.
Standby mode is still up to 30 days with this battery.
