According to Engadget’s battery benchmarks, which “involved looping an HD video,” the M1 MacBook Air can stay powered on for up to 16 hours and 20 minutes, which is about 5 hours more than the publication’s numbers for the latest Intel MacBook Air. That's also about 7 hours more than we got on our own battery benchmark for the the latest Intel MacBook Air.

The Verge found that the M1 MacBook Pro’s numbers are a little less impressive, which is to be expected with more power. The publication claimed to “easily get 10 hours on a charge” and said it had to resort to running 4K YouTube videos on Chrome in the background to drop that down to 8 hours.

The Verge is less optimistic on MacBook Air, though, saying it’s getting “between 8 and 10 hours of real, sustained work.”
