Use Adaptive Power to extend the battery life of your iPhone

Adaptive Power helps extend your iPhone's battery life when you use it more. It works automatically in the background, so you don't have to manage it. Adaptive Power uses on-device intelligence to predict when you'll need extra battery life based on your recent usage patterns and then adjusts as needed to help your battery last longer that day*. Adaptive Power doesn't manage performance while you use features that require maximum performance, such as when using camera or playing games with Game Mode on.

Adaptive Power is on by default on the following models:

  • iPhone 17

  • iPhone 17 Pro

  • iPhone 16

  • iPhone 16 Plus

  • iPhone 16 Pro
