“Ever since buying the first-generation 11-inch MacBook Air three years ago, my wish has been two-fold: make it faster and make it last longer between charges,” JP Mangalindan writes for Fortune.

“Apple took care of the performance issues in 2011, when it switched to a faster Intel processor. Paired with flash-based storage, apps launched briskly and zipped along,” Mangalindan writes. “Still, battery life remained a sore point for reviewers and critics. The company claimed the Air could get 5 hours in-between charges. In reality, with features like Wi-Fi turned on and brightness near maximum, battery life sometimes fell short, running for as little as 3 hours before having to shut down.”

Mangalindan writes, “With the 2013 11-inch MacBook Air, little has changed on the outside — it’s still the same svelte aluminum body — but Apple now promises what road warriors have wanted all along: all-day battery life. The 13-inch model is rated at 12 hours, and the 11-incher at 9. That’s 4-plus hours more than the previous Airs… My review unit is a $1,199 11-inch MacBook Air with 1.3GHz dual-core i5 processor, 4 GB of RAM, and 256 GB of flash storage. So far? It’s running like advertised. Apps launch, windows churn, and high-definition video all run a bit noticeably faster. With Wi-Fi on, the display’s brightness cranked all the way up, keyboard illuminated, and a few apps open like Spotify and Evernote, the MacBook Air’s battery indicator read 8.5 hours of charge left; with brightness ratcheted down to 3/4, the Air predicted 9.5 hours.”
