INCREDIBLE BATTERY LIFE

Battery life is always an important consideration when buying a new computer, and the new MacBook Air does not disappoint. The machine features a 50.3 watt-hour lithium polymer battery and, according to Apple’s testing, offers up to 12 hours of battery life whilst browsing the web, and up to 13 hours when watching iTunes movies. What’s more, the battery has up to 30 days of standby time, meaning you can go for days without charging and get the same power and performance as you would have had your Mac just been charged. Perhaps the most surprising thing about the new MacBook Air battery is that it performs better than all other Mac batteries, including the latest additions to the MacBook and MacBook Pro lineup.

On its product page, Apple says the new MacBook Air had a wireless web test, which “measures battery life by wirelessly browsing 25 popular sites with display brightness set to 12 clicks from bottom or 75%,” and stressed that “battery life varies by use and configuration.” Battery performance rarely lives up to advertised figures, but even if the device offers ten hours of continuous performance without charge, the Air will perform well against other laptops and offer enough juice for most consumers’ needs.
