A new feature called Adaptive Power in iOS 26 uses on-device intelligence to extend battery life on compatible iPhones by adjusting performance based on usage patterns. It analyzes user behavior over about a week and activates savings in power-intensive tasks like video recording or gaming. The setting is available only on models supporting Apple Intelligence.
Battery life ranks as a top priority for smartphone buyers, according to a CNET survey where 61% of respondents cited it as a reason for upgrading their devices. In iOS 26, Apple introduces Adaptive Power, a software tool designed to optimize energy use without user intervention. Unlike Low Power Mode, which activates at 20% battery and limits background tasks like email fetching, Adaptive Power functions more subtly.
Apple describes the feature in its iPhone user guide as follows: "It uses on-device intelligence to predict when you'll need extra battery power based on your recent usage patterns, then makes performance adjustments to help your battery last longer." It targets high-consumption activities, such as editing photos or playing games, and requires roughly a week to learn habits before engaging.
Compatibility is limited to iPhones capable of running Apple Intelligence: iPhone 17, iPhone 17 Pro, iPhone 17 Pro Max, iPhone Air, iPhone 16, iPhone 16 Plus, iPhone 16 Pro, iPhone 16 Pro Max, iPhone 16e, iPhone 15 Pro, and iPhone 15 Pro Max. The feature is enabled by default on the iPhone 17 series and iPhone Air, while other models require opting in via Settings > Battery > Power Mode. Users can enable Adaptive Power Notifications for alerts when it activates.
This builds on iOS 18's Gaming Mode, which prioritizes foreground apps at the cost of battery. Early tests on an iPhone 16 Pro show minimal disruptions, such as slight brightness adjustments, though effects vary. As more users update to iOS 26 or purchase new models, clearer insights into its effectiveness will emerge. Note that major updates often cause temporary battery drain during initial optimization.
