iPhone 15 pro to feature multi-use action button instead of mute switch?

Apple iPhone 15 Pro and iPhone 15 Pro Max models are rumoured to feature a customizable Action button like the Apple Watch Ultra, according to Macrumors website.

The source claimed the Action button will replace the Ring/Silent switch that has been included on every iPhone model since 2007. They did not explain how the Action button will work, but it will presumably be customizable like it is on the Apple Watch Ultra, allowing users to map the button to various system functions for convenient access.

It was already rumoured that the mute switch would be replaced with a button on iPhone 15 Pro models, but an Action button was mostly logical speculation until now.

The source claimed the Action button will continue to work for a period after an iPhone runs out of battery thanks to the inclusion of a new low-power chip.

In addition to an Action button, iPhone 15 Pro models are rumoured to have a singular volume button that can adjust the volume both up and down.

Both buttons are expected to have a solid-state design, meaning they will not physically move when pressed and instead provide haptic feedback from additional Taptic Engines to simulate the feeling of movement, similar to the Home button on the iPhone 7 and the latest iPhone SE.

Apple will likely unveil the iPhone 15 series in September. These changes are only rumoured for the Pro models, with the standard iPhone 15 and iPhone 15 Plus models still expected to have a mute switch and two volume buttons.
