Reply to comment by Airules in iPhone 15 Pro & Pro Max to be equipped with always-on “micro-processor” that will manage capacitive buttons and more even while the phone is powered down. by AppleXOS
Makes sense that most cases won't be compatible, and you'll have to buy an expensive case from Apple, or get one with ugly cutouts. Brave.

Silly. Of course they will be compatible. Have you seen how many third party cases have MagSafe? That’s a bit more of a engineering challenge than a capacitive button. There is absolutely no way there won’t be hundreds of third party options available day one which work with the buttons no problem whatsoever.

Haptic button, not just capacitive on the case.

The case doesn’t need haptics…
Capacitive is the method of registering input. Haptic is the method of feedback to the user. The case should conduct the vibration just fine unless it’s especially loose or padded for some reason.

FTA, there will be pressure sensitivity via the capacitive interface. I don’t think that will be easy to do and provide you with haptic feedback at the same time.

Already responded to your other comment first. But no that wouldn’t be difficult. Think about the screen.
If you long touch the top of the screen, there’s no Taptic Engine there. But you still feel it. The entire body of the iPhone conducts the vibration no matter where you actually touch.
The button itself needs to be capacitive to interact with the capacitive buttons. It could also just be straight up metallic with some sort of non-scratch bottom or just a thin enough plastic coating so as not to insulate the button. But the button would happily conduct the vibration of a second Taptic Engine is used as long as it’s in contact during the feedback tap. But I’m not convinced that’s actually necessary as one engine covers the entire phone for screen presses anywhere as-is.
They could certainly fit another engine in if they want to increase the strength of the haptic feedback or add more complexity, but it wouldn’t be strictly necessary. I’m more of the opinion that every cubic millimeter possible should be devoted to battery gains.

They had to redesign cases anyway for the last several years due to model changes. What made you think this year would magically be different?

Or they just make them with conductive elements in the case buttons

How will they conduct haptic feedback?

Okay. First, to be clear, do you understand the difference between capacitive and haptic? I don’t mean to be rude, but I need to know from which square we’re starting.

Yes.
Conductive - transfer the signal from your finger without a physical button.
Haptic - vibration feedback from the haptic/taptic engine, so that you can feel that something has happened, similar to the clicking of a physical button.
If there is a button cover on the case, it may be easy to make it conductive to transfer the signal, but how can they also transfer the haptic vibration to your finger? Maybe it's possible, but it feels like added complexity for very few positive reasons.

Per the other reply, it doesn’t have to go directly to the finger. The entire iPhone conducts the vibration from wherever Taptic Engine(s) lives. The same way you can feel the haptics when you touch the top of the screen even though the engine is at the bottom of the iPhone.

Yeah, good luck feeling it through a bulky case like an Otterbox. I guess we will see.
Sylvurphlame t1_jec3tzz wrote
If Otterbox cases stopped people feeling the haptics from screen touches, I think we’d be seeing the complaints. Or else the people using Otterboxes aren’t bothered by not feeling them.
kermityfrog t1_jec46kq wrote
Otterbox cases don't have a thick rubber bumper on the screen surface itself.
Sylvurphlame t1_jec4kao wrote
I bet you could feel it. It would be an r/MildlyInteresting experiment to have someone touch the screen while you held it.
