With the release of the first iOS 26.2 beta, we have already learned some of Apple’s plans for the future of its iPhone software. And it seems there’s more to come. Code discovered in today’s beta reveals that Apple has been experimenting with the ability to customize the side (Power) button, a feature that could work similarly to the Action Button introduced with iPhone 15 Pro.
Currently, pressing and holding the side button on the iPhone activates Siri, while a double-press brings up the Apple Wallet interface for contactless readers. Both actions are tied to Apple’s own services. For the first time, it seems that Apple may be considering letting users choose alternative behaviors for this button.
This change could be particularly significant in light of recent European regulations that push for greater user choice and interoperability. Apple has already made several adjustments to comply with EU requirements, including opening the iPhone to third-party app stores and allowing users to choose default browsers and payment systems.
Allowing customization of the side button might be another step in that direction. In the EU, users can already set an alternative payment app to open with a double-click.
While the feature isn’t functional yet in iOS 26.2 beta 1, internal code references suggest Apple is laying the groundwork. It’s unclear whether the company plans to release this option publicly. Some of the features that Apple tests internally never see the light of day.
Based on the code, the implementation seems strictly focused on letting users choose which app they want to open with the button as opposed to the shortcuts and settings available with the Action button.
We’ll be watching closely as Apple continues to develop and test iOS 26.2 over the coming weeks to see whether this Side Button customization makes its way into future betas. The update is expected to be released to the public in December.
