Hollister tested the QHD+ version and the 1080p version of the XPS 13, getting 5 hours and 6 hours respectively, while the MacBook Air 13 gave him 8.5 hours of practical use. Over at Gizmodo, Sean Hollister was also deeply disappointed: “Dell quotes up to 15 hours of battery life, and I struggled to get even half that in the real world.” But he, too, tested the XPS 13 agains the MacBook Air 13. He’s also planning to retest after disabling Windows Indexing and seeing the Dell’s life shoot from 7.5 hours to 9.5 hours. Here’s an important detail, though: Evangelho’s comparison was with a MacBook Air 13, which has a larger battery than the MacBook Air 11. The XPS13 can out perform the MacBook Air in battery life even with its high resolution screen. But is it poor battery life? Absolutely not.” Jason Evangelho of Forbes said: “Dell’s battery life claims miss the mark by a not-insignificant amount, and the XPS 13 still can’t match or exceed the Air in that department. Other outlets have actually expressed disappointment with the XPS 13’s run time. I’ll also be discussing other reviewers’ tests to help paint a more detailed picture.

We have to arrive at comparable numbers through reasoned use of similar tests. Time to test those claims.īefore we dig in, it’s important to note that there’s no single test that can compare PC and MacBook battery life directly. But now we have a real contender: The Dell XPS 13. Colleagues who drive MacBook Airs claim they can get all-day battery life, and that no similarly sized PC can do the same. The MacBook Air’s battery life is legendary.
