last Apple intelligence Features get all the attention, but… iOS 26 One of my favorite tools does its work quietly in the background. on iPhone On models capable of running Apple’s AI technology, the Adaptive Power setting works behind the scenes to boost battery power, even on many older iPhones.
Currently, your iPhone uses as much power as it needs to perform its tasks. You can extend battery life by Take some simple stepssuch as reducing screen brightness and disabling the always-on display. Or, if your battery is low, you can turn on Low Power Mode, which limits background activity, such as fetching mail and downloading data, and dims the screen to help Extend battery life. Low Power Mode also turns on automatically when the battery level reaches 20%.
If Low Power Mode is the hammer that reduces power consumption, Adaptive Power is the scalpel that intelligently cuts power savings here and there as needed. And based on Apple’s description accompanying the control, the savings will be mostly felt in power-hungry situations like recording videos, editing photos, or even playing games.
Apple says Adaptive Power takes about a week to analyze your usage behavior before it starts actively working. It runs in the background without requiring any administration on your part.
Here’s how Apple describes it iPhone user guide: “It uses on-device intelligence to predict when you’ll need additional battery power based on recent usage patterns, then makes performance adjustments to help your battery last longer.”
Watch this: The iPhone 17 Pro Max has incredible battery life
Which iPhone models can use adaptive capability?
The feature uses artificial intelligence to monitor and choose when to activate power-saving measures, meaning only phones compatible with Apple Intelligence get this feature. These are the models that have the option:
• iPhone 17
• iPhone 17 Pro and iPhone 17 Pro Max
• iPhone Air
• iPhone 16 and iPhone 16 Plus
• iPhone 16 Pro and iPhone 16 Pro Max
• iPhone 16e
• iPhone 15 Pro and iPhone 15 Pro Max
Although some iPad and Mac models support Apple Intelligence, the feature is only available on iPhones.
How to turn on adaptive power
Adaptive Power is turned on by default on iPhone 17, iPhone 17 Pro, iPhone 17 Pro Max, and iPhone Air. For other models, you must subscribe to use them. In iOS 26, you’ll find the Adaptive Power toggle in Settings > Battery > Power Mode. To be alerted when the feature is active, turn on the Adaptive Power Notifications option.
In iOS 26, turn on the Adaptive Power setting to help extend battery life.
Adaptive capability feels like an outgrowth of Game Mode, introduced in iOS 18, which directs all available processing and graphics power to the foreground app and pauses other processes in order to deliver the best possible experience — at the expense of notable battery life.
When your iPhone uses Adaptive Power, a notification appears.
What does this mean for your charging habits?
Although we all want as much battery life as possible all the time, judging by the description, it seems as though Adaptive Power’s improvements won’t always be active, even if you leave the feature turned on. The phrase “when battery usage is higher than usual” can include a limited number of situations. However, taking into account that according to A CNET poll61% of people upgrade their phones because of battery life, and a feature like Adaptive Power can extend the life of their phone once they update to iOS 26.
I also wonder if adjusting the screen brightness slightly might be annoying, but in my experience so far, it hasn’t been noticeable. Since the feature also selectively de-prioritizes processing tasks, external influences appear minimal. When activated on the iPhone 16 Pro, the only indication was the Adaptive Power alert that appeared.
We’ll get a better idea of how well Adaptive Power works as more people adopt iOS 26 and start buying new iPhone models. Also remember that shortly after installing a major software update, it’s common to experience worse battery life as the system optimizes data in the background; Apple went so far as to remind customers that it is a Temporary side effect.
