Last week, we noted that iOS 26 introduces an Opt-in adaptive power mode on the iPhone, alongside the existing low power mode.

Apple says that the adaptive power supply mode can make “small performance adjustments” when necessary to extend the battery life of an iPhone, including a slight writing of the screen brightness or allow certain activities to “take a little more time”.

The full description of the adaptive power mode, of the first iOS 26 beta:

When your use of the battery is higher than usual, the iPhone can make small performance adjustments to extend the life of your battery, including a slight writing of the screen brightness or allow certain activities to take a little more time. Low power mode can light up at 20%.

IOS 26 is compatible with the IPhone 11 series and more recent, but unfortunately, the adaptive power mode is only available on iPhone 15 pro and more recent models. Indeed, the functionality fueled by AI requires an iPhone that supports Apple Intelligence.

We have confirmed that the adaptive power mode is not available on the iPhone 14 Pro and less.

The functionality is available on the following iPhone models:

  • iPhone 15 pro
  • iPhone 15 pro max
  • iPhone 16th
  • iPhone 16
  • iPhone 16 Plus
  • iPhone 16 pro
  • iPhone 16 pro max

The adaptive power supply mode could end up being particularly beneficial on the air of the iPhone 17, which should have an ultra-thin design which will limit the size of the device of the device. However, Apple planned to publish an iPhone 17 air battery case.

The adaptive power supply mode is disabled by default. The option can be activated continuously in the application of settings under the battery → Power mode.

iOS 26 is currently in beta version. The update will probably be published in September.
