The Action button, introduced with the iPhone 15 Pro models and now featured on all iPhone 16 models, offers users a customizable hardware button for quick access to various functions. With iOS 18, Apple has expanded its capabilities to include Control Center functions, which could potentially increase its utility for many users.
Despite its versatility, user adoption of the Action button has been mixed. For example, in April 2024 a MacRumors survey of iPhone 15 Pro users revealed that while some found the button a "game changer," particularly for activating custom Shortcuts, over half of respondents often forgot the button is even there. The most common uses among those who did use it included activating the camera or flashlight – functions already accessible via the default Lock screen.
However, the new ability to assign Control Center functions to the Action button may change its reception, and could address common criticisms about its limited usefulness. By providing quick access to frequently used Control Center settings, it may solve the "out of sight, out of mind" problem and make the Action button more integral to your daily iPhone use. For those looking to give the Action button another chance or maximize its potential, here's how to set it up:
- Open the Settings app on your iPhone.
- Scroll down and tap Action Button.
- Swipe through the available actions until you reach Controls.
- Tap the chevrons next to "Choose a Control."
- Scroll through the Control Center options or use the search bar at the top to find a specific control.
- Tap on the desired control to assign it to the Action button.
