Apple has announced a major change coming to the iPhone 15 Pro models – a new customizable Action Button is replacing the familiar mute switch. This reinvented side button can still silence calls and alerts with a simple press but also enables quick access to a variety of shortcuts and actions.

Functionality of the Action Button

On previous iPhone models, the mute switch on the side allowed users to quickly toggle between ring and silent modes. The new Action Button keeps this same default behavior:

  • Pressing and holding the Action Button will switch the phone from ring to silent and vice versa.
  • Distinct haptic feedback will confirm which state you have entered.

So, by default, the Action Button provides the same quick mute function iPhone users are accustomed to.

Customizable Actions

Where the Action Button differs from the previous mute switch is in allowing custom actions to be assigned:

  • A single press can be set to launch apps, run shortcuts, enable accessibility features like Live Speech, and more.
  • The actions available cover a wide range of iPhone functionality beyond just muting.
  • Users can switch between various sets of actions by pressing and holding the button.

So, with some configuration, the Action Button can do much more than the simple mute switch offered before.

Examples of Action Button Uses

Here are some examples of how the Action Button could be customized and used:

  • Single press to open Camera and quickly take photos.
  • Single press to start Voice Memos to record ideas on the go.
  • Single press to launch your most used app like Safari or Messages.
  • Single press to turn on Live Speech for accessibility assistance.
  • Single press to run Shortcuts that automate multiple steps.
  • Single press to pull up Apple Pay when entering stores.

The possibilities are nearly endless for what actions users can assign for quick access. The new level of customization makes the Action Button far more versatile than a dedicated mute switch.

Implementation on iPhone 15 Pro

The Action Button is set to debut on the upcoming iPhone 15 Pro models, replacing the mute switch that has been present since the first iPhone launched in 2007.

The non-Pro iPhone 15 models will keep the standard mute switch for now. But the Action Button could expand to the full iPhone lineup in future releases if it proves popular.

For iPhone 15 Pro users, some learning will be required to get used to the new Action Button and customize it to their needs. But the ability to quickly trigger their most used actions will make it a worthwhile upgrade over the simpler mute switch.

Apple seems to be aiming for more personalized iPhones, and the new Action Button is a significant step in that direction by letting users define its functionality.
