Better MacBook Battery Life Coming With macOS 27
Your MacBook may be getting a battery performance upgrade later this year, thanks to Apple's next major macOS software update, reports Bloomberg's Mark Gurman.
In his latest Power On newsletter, Gurman says that beyond the visual tweaks and fixes coming to Liquid Glass in macOS 27, Apple is also zeroing in on "battery-life upgrades and performance improvements." It sounds like the sort of under-the-hood boost that rarely makes a WWDC keynote, but for anyone whose MacBook no longer lasts all day on a single charge, it's arguably more welcome than another redesign.
The battery improvements should also provide a nice addition to smaller functional changes related to power usage that Apple has already made in macOS Tahoe. In macOS 26.4, Apple added a Charge Limit setting that caps charging anywhere from 80 to 100 percent to preserve long-term battery health, as well as a new "Slow Charger" indicator that warns users when their adapter isn't delivering enough wattage.
Apple is set to unveil macOS 27 at WWDC on June 8, with a public release expected in September.
