Apple Returns to Project Bongo: Haptic Buttons Are Coming to All Devices!

Apple appears to be continuing to invest in developing active solid-state buttons with haptic feedback, not only for iPhone but also for future iPad and Apple Watch models, according to reports emerging from China.

In 2022, reports suggested that Apple was planning to incorporate these buttons into the iPhone 15 Pro as part of a project codenamed "Project Bongo". Solid-state haptic buttons promise reduced wear thanks to the absence of mechanical movement, as well as the ability to detect different levels of pressure to carry out different commands. Although initially planned for the iPhone 15 Pro, the idea was dropped and subsequently moved to the iPhone 16 Pro, before ultimately being postponed indefinitely.

However, it seems that Apple never completely abandoned this technology. The user “Instant Digital” on the Chinese platform Weibo raised the topic again last month, claiming that the company is continuing to test haptic buttons for a future iPhone. In fact, in a recent post, they said that the project had expanded to cover Apple's entire product range, including not only iPhone but also iPad and Apple Watch.

According to their information, the delay in implementation is not related to production costs, but to technical challenges concerning the precision of the haptic response. The design involves integrating the buttons directly into the device's frame, with no mechanical rebound when pressed. Apple is reportedly trying to replicate the feel of a traditional mechanical button as closely as possible.

Project Bongo appears to have been temporarily put on hold while Apple prioritised other technological improvements, such as those to displays and batteries. Although haptic buttons are not expected to feature on the iPhone 17, the latest reports suggest that the project has been revived within the company.
