The iPhone 16 series brings a lot of changes, such as different displays on some models, a wider implementation of the exceptional tetraprism camera, a new thermal design to prevent overheating, improved battery life, and an improved main camera sensor. But the new capture button for taking photos or videos could mean there’s a surprising new cover for it. And the report also leaks that it looks like the new button will be included on all new iPhones.

The thing about the record button is that it’s rumored to be capacitive, so you can half-press it to focus before fully pressing it to take a shot. Swiping right and left will presumably zoom in and out.

A capacitive button, like the iPhone’s touchscreen, works via a weak electric field that reacts when another electric field (specifically, your finger) interrupts it. This is why you can’t use capacitive screens underwater, for example.

Therefore, it was assumed that phone cases would have holes in them to allow easy access to the record button.

However, according to a leak from @DuanRui, it seems that Apple’s own silicone cases for the iPhone do not have a gap, but rather a piece of material over where the button is located.

The post shows images of alleged third-party iPhone 16 cases that have a gap right where the record button is supposed to be. And I can confirm that the (many) iPhone 16 cases that were sent to me for testing all have this gap.

But the post states (in a Google translation from Chinese): “It is said that Apple’s official iPhone 16 series protective case will not have this opening and will have an integrated design that will not affect the normal use of this capacitive button.”

Well, covering the button makes sense in a way: you don’t want to keep accidentally pressing the shutter button with your finger, do you?

But the material in question is a mystery. The thing is, you can increase the distance at which capacitive keys can detect interaction. I remember seeing a Microsoft keyboard where the distance was so high that if you touched it from half a meter away, the backlight would turn on. The same principle means that on many phones you can interact with the display while wearing gloves.

Maybe this button can be controlled through a physical barrier, just like the gloves. Or maybe it’s a bespoke material – hey, Apple could license it!

As mentioned above, the most important takeaway from all this is that, according to third-party cases, the Capture Button will be available on the iPhone 16 and 16 Plus, not just the Pro versions—something some people, like Bloomberg’s Mark Gurman, were unsure about.
