The Action button is real, and it's positioned where the mute switch has lived
Since the original iPhone arrived in 2007, a small mute switch has occupied the same quiet corner of Apple's flagship device — a fixture so familiar it became invisible. Now, with case manufacturers already engineering their products around new technical blueprints, it appears that corner is changing: the iPhone 15 Pro will carry an Action button in its place, a shift that signals Apple's ongoing effort to make its premium line feel meaningfully distinct. The volume buttons, by contrast, will remain reassuringly mechanical — a reminder that not every familiar thing is being left behind.
- Mixed signals from earlier leaks had cast doubt on whether the Action button would survive Apple's redesign process at all, leaving the feature's fate genuinely uncertain.
- CAD files circulating among case manufacturers — the same technical blueprints used to engineer real products — now confirm the Action button is real and positioned exactly where the mute switch has lived for sixteen years.
- Rumors of solid-state volume buttons have been put to rest; the clickable, mechanical feel users already know from the iPhone 14 Pro is staying, suggesting Apple weighed user preference over novelty.
- The camera bump is slightly less dramatic than earlier leaks implied, and the Action button's actual functionality remains unannounced — two threads still dangling ahead of an expected September reveal.
The iPhone 15 Pro is coming into focus, and the clearest picture yet arrives not from Apple, but from the case manufacturers already building around it. CAD files — the technical blueprints that accessory makers rely on to engineer their products — confirm what had been uncertain: the Pro model will replace its mute switch with a dedicated Action button, ending a design tradition that stretches back to the original iPhone in 2007.
The confirmation matters because Apple had muddied the waters. Earlier reports raised doubts about whether the Action button concept would survive at all, and speculation about solid-state volume controls added further uncertainty. The new renders resolve both questions: the Action button is coming, and the volume buttons will remain traditional, mechanical, and clickable — the kind that offer real tactile feedback rather than touch-sensitive substitutes.
The camera bump also gets a quiet revision. It will still be larger than what sits on current iPhones, but slightly less imposing than some leaks had suggested — a small detail that could matter to anyone who sets their phone face-up on a desk.
Importantly, none of this applies to the standard iPhone 15 or 15 Plus, which will keep the mute switch. Apple's long-standing strategy of distinguishing its Pro and entry-level lines remains intact.
With an announcement expected in September, the biggest open question is what the Action button will actually do. Apple has confirmed the hardware; the software story is still to come.
The iPhone 15 Pro is shaping up to look different from what came before, and now we have something close to proof. Case makers are already building their products around CAD files that show Apple's next flagship phone, and those technical blueprints reveal a design choice that had been uncertain until now: the Pro model will ditch the mute switch in favor of a dedicated Action button.
This matters because Apple had sent mixed signals. Earlier reports suggested the company might abandon the idea of a solid-state button arrangement altogether, leaving some wondering whether the Action button would survive the redesign. But the new renders, shared by 9to5Mac and based on the actual CAD data manufacturers use to engineer their cases, show it's still coming. The Action button is real, and it's positioned where the mute switch has lived since the original iPhone in 2007.
What's equally important is what didn't change. The volume buttons will remain traditional, clickable buttons—not the solid-state touch-sensitive design that had been rumored. They'll feel and sound like the ones on the iPhone 14 Pro, with actual mechanical feedback. That's a decision that suggests Apple is listening to users who prefer tactile controls over touch-sensitive alternatives.
The renders also hint at a modest adjustment to the camera bump. It will still be larger than what's on today's iPhones, but not quite as pronounced as some earlier leaks had suggested. It's a small refinement, but one that could matter to people who care about how their phone sits on a table or fits in a pocket.
One crucial detail: this redesign applies only to the Pro models. The standard iPhone 15 and iPhone 15 Plus will keep the mute switch, maintaining the distinction between Apple's entry-level and premium lines. That split has been part of Apple's strategy for years, and it's staying put.
Apple is expected to announce these phones sometime in September, which means there's still time for more leaks and refinements before the official reveal. The Action button itself remains something of a mystery—we know it's coming, but Apple hasn't yet explained what it will do or how users will configure it. That's the next piece of the puzzle, and it's likely to be one of the more interesting announcements when the company finally takes the stage.

These renders are based on CAD files that case makers are using to build their products— reporting from 9to5Mac
The Hearth Conversation Another angle on the story
So these CAD renders—they're not just rumors or speculation. Case makers are actually building from these files?
Exactly. Case manufacturers need precise measurements to make products that fit properly. If they're using these CAD files, it means Apple has already locked in the design and shared it with suppliers. That's as close to confirmation as you get before an official announcement.
And the Action button replaces the mute switch entirely on the Pro models?
On the Pro, yes. The standard iPhones keep the mute switch. It's part of how Apple differentiates the product lines. The Pro gets the new button; everyone else gets the familiar switch.
But we still don't know what the Action button actually does?
Not yet. Apple will reveal that when they announce the phone. It could be programmable, it could be tied to specific features—we're just seeing the hardware confirmation right now, not the software story.
The volume buttons staying clickable instead of solid-state—is that surprising?
A little, actually. There had been real speculation that Apple might go full touch-sensitive. But clickable buttons have better tactile feedback, and people seem to prefer that. This suggests Apple heard that feedback.
What about the camera bump getting slightly smaller?
It's a refinement. Still bigger than the current generation, but not as extreme as some feared. It's the kind of detail that matters more to people who care about how their phone feels in hand than to anyone else.
