I’m willing to bet most of us want just one thing from our iPhones: longer battery life. Apple may continue to add new features and designs with each new version of its smartphone, but if the company simply announced a new iPhone with record-breaking battery life, buyers would be thrilled.
While we may have to wait until the iPhone can go a couple of days without a charge, Apple added a new feature in iOS 26 to extend your iPhone’s battery life. Adaptive Power uses built-in AI to analyze your iPhone usage and predict when you’ll need extra battery life. This is exactly how I want AI to be used—not for creating hyper-realistic videos or musical dross .
How Adaptive Power tries to increase battery life
When Adaptive Power decides it’s time to kick in, it can adjust your iPhone’s performance level. This may cause some tasks to take longer than usual, but this slower speed supposedly saves battery life. Adaptive Power also reduces screen brightness by 3%, limits background activity, and, when your iPhone reaches 20%, turns on Low Power Mode without prompting you. Apple isn’t entirely clear on the difference between Low Power Mode and Adaptive Power overall. From what we know, it appears Adaptive Power simply reduces processing speed at regular intervals and only slightly reduces brightness, while Low Power Mode slows the display’s refresh rate and speed, and limits brightness, 5G, iCloud syncing, and email retrieval, among other tasks.
Adaptive Power is enabled by default on Apple’s newest iPhone models, including the iPhone 17, iPhone 17 Pro, iPhone 17 Pro Max, and iPhone Air, the latter of which will likely benefit from the feature . On all other compatible iPhones, including the iPhone 15 Pro and later, the feature is disabled by default. This means that unless you have an iPhone 17, you’ll need to enable it yourself.
How to turn Adaptive Power on or off
Whether you’re using an iPhone 15 Pro or iPhone 17, the Adaptive Power controls are all in one place. Open Settings, then select Battery > Power Mode . Here, you can turn Adaptive Power on or off by tapping the switch next to “Adaptive Power.”
Since Adaptive Power turns on and off throughout the day, Apple also offers you the option to receive notifications when it’s active. This setting can be adjusted using the “Adaptive Power Notifications” toggle.
I’ve been using Adaptive Power since iOS 26 was released on September 15th , but it’s hard to say whether it’s had a noticeable impact on my battery life. I think it would be helpful if Apple added Adaptive Power information to my battery stats so I could compare the impact before and after using it. For now, I’ll continue using it, at least to give my battery the best chance of lasting the rest of the day without recharging.
