Even though we are currently in the era of the iPhone 16, examining past Apple prototypes offers fascinating insights into features that were ultimately discarded throughout the development phases. This particular rare prototype of the iPhone 14 Pro provides an intriguing glimpse into the potential design of the anticipated haptic volume button.
This iPhone 14 Pro prototype predates the iPhone 13
Early speculations regarding the iPhone 15 Pro emerged in early 2022, proposing the inclusion of solid-state buttons for volume control and the mute switch. However, this concept did not materialize as expected, leading Apple to retain traditional buttons. Notably, even the recently introduced Action Button remains a mechanical button with operational components.
The YouTube channel “Apple Demo,” renowned for unveiling Apple prototypes, has introduced a rare prototype of the iPhone. This prototype originates from May 2021, preceding the iPhone 13’s launch. However, as Apple Demo pointed out, the iPhone 13 and 13 Pro prototypes were already nearing their final development stages at that time.
This implies that the displayed prototype represents an early iteration of the iPhone 14 Pro, rendering it exceptionally rare. The existence of Dynamic Island on the display essentially verifies this claim.
Nonetheless, this prototype diverges significantly from the finalized design of the iPhone 14 Pro. Internally, it houses a combination of components from both the 13 Pro and 14 Pro. The logic board resembles that of the iPhone 13 series, but notably, it omits the SIM card slot. Interestingly, the battery is encased in metal, similar to the design seen in the iPhone 16 Pro.
The speculated solid-state volume button
One standout feature on this prototype is its volume button configuration. Rather than the typical dual buttons for volume adjustments, this device sports a singular large button alongside the traditional mute/ring switch. This reinforces the idea that Apple has been testing solid-state buttons for some time.
The prototype bears the engraving “RANGER-DROP” on its side, indicating it was designed for durability evaluations. With no functional cameras or microphones present, it appears this prototype was specifically created to assess the new volume button.
During that period, there were rumors suggesting Apple aimed to remove all mechanical buttons from the iPhone, intending to enhance the number of Taptic Engines within the device to offer improved haptic feedback when interacting with solid-state buttons.
Nevertheless, analysts reported that Apple abandoned this concept due to its inherent complexities. Some prototypes of the iPhone 15 Pro were also created featuring the modified volume button, but the idea was ultimately tabled again. The iPhone 16 lineup continues to feature traditional up and down volume buttons.
It remains uncertain whether Apple still intends to roll out solid-state buttons, particularly with the new Camera Control incorporating moving components. What are your thoughts? Would you welcome such technology on the iPhone? Share your opinions in the comments below.
