Testers of the iOS 26 beta version have discovered a new useful feature in the firmware. With its help, the iPhone will be able to work longer on a single battery charge – however, such a “boost” will not be without pitfalls.
When you activate the Adaptive Power switch, the smartphone will start monitoring the intensity of battery consumption. If at some point it turns out to be higher than average, the iPhone will start reducing hardware performance in order to improve battery life: reducing the brightness of the display backlight and/or the processor frequency. When the charge level reaches 20%, the standard power saving mode may automatically turn on.
Bloomberg reported roughly the same thing back in May, referring to the thin iPhone 17 Air with a relatively small battery capacity. The Adaptive Power switch can already be found in the settings menu of the test version of the new operating system. The public “beta” of iOS 26 will be released in July, and the stable release will begin to be distributed in the fall.
