Apple is actively exploring stolid-state buttons with haptic feedback, not just for the iPhone, but also for future iPad and Apple Watch models, claims a rumor out of China.
Back in 2022, several reports suggested that Apple intended to bring solid-state buttons to the iPhone 15 Pro in 2023 as part of ”Project Bongo.” Solid-state haptic buttons reduce mechanical wear, while enabling users to differentiate between a light press and a firm press to trigger different functions. However, the plan was reportedly canceled at a late stage. They were then rumored to come to the iPhone 16 Pro, before being shelved indefinitely.
