Kup says the volume and power buttons on next year’s two high-end iPhone models may adopt a solid-state design, similar to the iPhone 7’s home button. The new solid-state buttons would replace the current mechanical button design. The new buttons would likely use a method similar to Apple’s Mac trackpads, which mimic the physical feeling of being pressed with small vibrations.
My latest survey indicates that the volume button and power button of two high-end iPhone 15/2H23 new iPhone models may adopt a solid-state button design (similar to the home button design of iPhone 7/8/SE2 & 3) to replace the physical/mechanical button design.

Kuo believes the new iPhones will reportedly increase the number of Taptic Engines in each iPhone from one to three, adding them on the internal left and right sides to provide feedback to users, making it seem as though they are pressing physical buttons.
In an additional thread, Kuo said that “the buttonless design and switch to USB-C are two of the major updates for iPhone 15.”
