Check out the iOS 26 feature that will extend your iPhone’s battery life
Apple had been rumored to be developing an AI-based battery optimization feature for iOS 26. Keeping Adaptive Power enabled at all times should allow iPhone users to enjoy some extended battery life. Unless you install the iOS 26 beta, you’ll have to wait for the stable version of iOS 26 to be released in September to enjoy it. Right now, to have the Adaptive Power toggle on your iPhone, you’ll have to be running the iOS 26 Developer Beta.

The iPhone will also compare how much battery life you have remaining and compare it to the battery life you had at similar times on other days. For example, under the Daily Usage heading, my iPhone 15 Pro Max said “You’re using a similar amount of battery today as you usually do by 1:00 AM.”
