Overview

  • The iOS 26 developer beta introduces Adaptive Power Mode to extend device runtime through subtle performance adjustments.
  • Adaptive Power Mode conserves battery by lowering display brightness and allowing some tasks to run at reduced speeds.
  • The feature operates alongside Low Power Mode and will automatically switch to it when battery levels fall to 20 percent.
  • Support is limited to iPhone 15 Pro and newer models, with compatibility extending to iPads running iPadOS 26.
  • Apple plans to expand iOS 26 beta access to more users next month and roll out the public release in the fall.
