Apple is vigorously pursuing solid-state button technology integrated with haptic feedback, a feature poised to revolutionize not only the iPhone but also future iPad and Apple Watch models. Early whispers in 2022 suggested Apple's ambition to introduce these innovative buttons via the "Bongo Project" for the anticipated iPhone 15 Pro in 2023. Despite the iPhone 15 Pro ultimately forgoing this design, Apple remains undeterred in its quest to perfect solid-state buttons. The company continues to refine the haptic design and ensure reliability over extended use. The solid-state button concept aims to minimize openings, bolster protective capabilities, and facilitate diverse triggering mechanisms, thereby empowering a single button to fulfill multiple functions.
