Apple Plans iOS 27 Overhaul for Better Battery Life

Apple is preparing a significant internal overhaul for its upcoming iOS 27 software update, with changes aimed at improving battery life through code optimization, according to a report from Bloomberg journalist Mark Gurman. The effort, which could benefit iPhones across a range of models, is expected to be unveiled at the company's Worldwide Developers Conference in June 2026 and released to users in the fall of that year.

Gurman, in his Power On newsletter, described iOS 27 as a "cleanup job" focused on refining the operating system's underlying code. Engineers are reportedly removing outdated elements, rewriting existing features, and making subtle upgrades to applications to enhance overall efficiency. This approach mirrors Apple's 2009 Mac OS X Snow Leopard release, which emphasized stability and performance over new additions. The result, Gurman noted, should be a "snappier, more responsive" system that reduces inefficiencies contributing to battery drain.

The push for better battery life comes amid user complaints about power consumption in the current iOS 26, which introduced the Liquid Glass interface and led to noticeable slowdowns, particularly on older iPhone models....
