iPhone 15 Pro and iPhone 15 Pro Max unveiled a couple of weeks ago feature Action Button, which replaces the mute switch. According to MacRumors, the iPhone 16 series will also come with a capacitive button, internally named “Capture Button” and codenamed “Project Nova.”

There will be a capacitive Capture Button on the iPhone 15’s right-side frame, where the Power Button is located, but lower, near the mmWave cutout. Because the Capture Button is placed where the mmWave cutout is, it is moved below the volume buttons to the left-side frame.

Although its purpose is unclear, the Capture Button should work like the Home Button on the iPhone SE, mimicking the press of a physical button. According to the source, the Capture Button will also have a force sensor. In addition, unlike the Action Button, which is only available on the iPhone 15 Pro and iPhone 15 Pro Max, the Capture Button will be available on all iPhone 16 models.

A fallback device without the Capture Button has also been created by Apple as a backup.

The iPhone 16 series will also feature a capacitive Action Button called “Project Atlas.” Like the Capture Button, it will provide haptic feedback using strain gauges and reluctance motors.

Moreover, the iPhone 16 is expected to feature a redesigned camera bump and vertical camera arrangement, while the iPhone 16 Pro and iPhone 16 Pro Max are expected to feature 6.3″ and 6.9″ screens, respectively. They are 0.2″ larger than their predecessors.

It’s worth keeping in mind that all this information is based on pre-production models, and since the iPhone 16 lineup’s design isn’t finalized, there’s always a chance we’ll get a completely different product at launch.
