Apple Watch Ultra users enjoy a physical Action Button with customizable functions, but other models lack this feature. This explainer breaks down current button roles, the proposed software tweaks for watchOS 27, and what these changes could mean for all Apple Watch users.

Currently, the standard Apple Watch models do not offer this level of button customization. With the upcoming watchOS 27, there is a discussion about potential software changes to bring a similar customizable button experience to all Apple Watches. Understanding these proposed changes requires a look at how the buttons function today and what the new possibilities might be.
Current Apple Watch Button Layout and Functions
All Apple Watch models except the Ultra come equipped with two main physical buttons: the digital crown and the side button. Each serves distinct functions:
Digital crown: A single press opens the app launcher; double press switches between apps; holding it activates Siri.
Side button: A single press opens Control Center; double press launches Apple Pay; holding it brings up the power off menu.
The Apple Watch Ultra adds a third button — the physical Action Button. This button can be customized by the user to open specific apps, such as the workouts app, offering quick access without navigating through menus.
Power Management and Reset Controls on Apple Watch and iPhone
Powering off and resetting the Apple Watch currently involve specific button combinations. For example:
- Power off Apple Watch: Typically accessed by holding the side button to open the power menu.
- Force reset Apple Watch: Holding both the side button and digital crown for 10 seconds triggers a force reset.
- iPhone differences: Since the iPhone X, holding the side button launches Siri, not the power menu. To power off an iPhone, users must hold the volume up button and the side button simultaneously.
These differing control schemes between Apple Watch and iPhone can cause some confusion. The force reset’s 10-second hold on the Apple Watch might be too short to allow a straightforward power-off option for users holding the same buttons, highlighting an opportunity for improvement.
The Proposal: Customizable Button Functions for All Apple Watches
An author writing for 9to5Mac suggests several software changes that could enhance Apple Watch usability, particularly around button functionality:
- Extending the hold time for the side button and digital crown combination from 10 seconds to 20 seconds, enabling users to power off the watch using this method more easily.
- Repurposing the action triggered by holding the side button into a customizable Action Button function for all Apple Watch models, not just the Ultra.
- Alternatively, allowing users to remap the double-click action of the side button to launch custom apps or perform specific functions.
These changes would bring the customizable convenience of the Apple Watch Ultra’s physical Action Button to a wider audience, making everyday interactions smoother and more personalized.
Why Button Customization Matters
Customizable buttons can significantly improve user experience by tailoring device interactions to individual preferences. For Apple Watch users who primarily use their device for activity tracking, quick access to the workouts app via a dedicated button enhances efficiency. Extending this feature to all models could make the watch more versatile and intuitive.
Furthermore, simplifying power management controls by adjusting hold durations and button functions could reduce user frustration and accidental resets, especially for those less familiar with the current combinations.
Context and Considerations
As of now, Apple has not officially announced plans to implement these changes in watchOS 27 or future updates. The suggestions come from outside observers proposing improvements based on user experience and device capabilities.
Technically, adding software-based button remapping is feasible and exists in various forms on competing smartwatches. However, Apple’s design philosophy emphasizes simplicity and reliability, which may influence how extensively such customization is offered.
If implemented, these changes could enhance accessibility and make the Apple Watch more adaptable to diverse user needs, potentially setting new standards for smartwatch interaction.
FAQs
What is the Action Button on the Apple Watch Ultra?
The Action Button is a physical button unique to the Apple Watch Ultra that users can customize to perform specific tasks, such as opening the workouts app quickly.
How do the digital crown and side button currently function on Apple Watches?
The digital crown opens the app launcher (single press), app switcher (double press), and Siri (hold). The side button opens Control Center (single press), Apple Pay (double press), and the power menu (hold).
How is powering off and resetting the Apple Watch handled now?
Holding the side button brings up the power off menu. Holding both the side button and digital crown for 10 seconds triggers a force reset. This differs from iPhone controls, where powering off requires holding volume up and side button together.
What software changes are proposed for watchOS 27?
The proposal includes extending the hold duration for the force reset combination to 20 seconds to allow powering off, repurposing the side button hold as a customizable Action Button, and enabling remapping of the side button double-click action.
Who would benefit from these proposed changes?
All Apple Watch users could benefit, especially those without the Ultra model, by gaining more customization and simplified power controls.
If you own an Apple Watch and are interested in enhanced button customization, keep an eye on announcements related to watchOS 27 updates. While these changes are not confirmed, understanding current button functions can help you make the most of your device today.
Apple Watch Ultra users can already enjoy the benefits of the physical Action Button, but if you have a standard model, consider providing feedback to Apple about your interest in customizable controls. This can influence future software improvements.
