Say Goodbye to the iPhone 15 Pro's Buttons! Apple's Latest Supplier Confirms Revolutionary Change

According to recent reports, the speculation about Apple using solid-state volume buttons on the iPhone 15 Pro may not be happening after all. Apple supplier Cirrus Logic has given a hint that the project has been cancelled and the company will revert to normal, clickable buttons. 

The supplier has informed investors in a letter that a product previously scheduled for introduction this fall will no longer come to market as planned, but cannot disclose that Apple was its customer for this tech due to confidentiality agreements. This news almost confirms the rumors about the abandonment of the solid-state volume buttons.

HPMS is a term used by Cirrus Logic to describe a high-performance, mixed-signal segment that includes the haptic drivers for Apple's Taptic Engine in iPhones. If Apple had introduced solid-state buttons, the iPhone 15 Pro would have had two extra Taptic Engines to provide haptic feedback for these buttons.

Cirrus Logic previously implied in a shareholder letter that it supplied the haptic drivers for Apple's Taptic Engine, without explicitly stating it. Apple is Cirrus Logic's biggest customer, responsible for 78% of its revenue in the 2022 fiscal year.

Ming-chi Kuo, who often shares Apple-related rumors, suggests that the iPhone 15 Pro won't have solid-state buttons due to "unresolved technical issues before mass production". In simpler terms, there were problems that prevented the buttons from being made in large quantities.

Despite the cancellation of the solid-state buttons, the iPhone 15 Pro is still set to introduce a new feature: the Action button. This button will replace the ring/mute switch and is expected to be fully customizable, similar to the Apple Watch Ultra. While the volume buttons will remain the same, the Action button will add a new level of functionality and personalization to the iPhone 15 Pro.

Analyst Jeff Pu suggests that Apple may not have completely abandoned the idea of solid-state volume buttons. Instead, the company may postpone the introduction of this technology until next year, with plans to include it in the iPhone 16 Pro.
