According to a support document published by Apple today, the iPhone Air, iPhone 17, iPhone 17 Pro, and iPhone 17 Pro Max will all come with iOS 26's Adaptive Power Mode pre-enabled straight out of the box. This innovative feature leverages intelligent on-device algorithms to analyze and learn from user behavior, automatically optimizing power consumption to prolong battery life. The system typically requires around 7 days to fully adapt to a user's habits and is compatible with the iPhone 15 Pro series, all iPhone 16 models, and all iPhone 17 models. However, it's worth noting that only the iPhone 17 series and iPhone Air will have this feature activated by default; for other models, users will need to manually enable it. Once activated, Adaptive Power Mode can intelligently adjust performance settings, slightly reduce screen brightness by 3%, and limit background activities to conserve energy. The iPhone 17 series boasts impressive battery longevity, with the iPhone Air offering up to 27 hours of continuous video playback—a figure that can be extended to a remarkable 40 hours when paired with a MagSafe external battery pack.
