Apple may introduce solid-state buttons in all-glass iPhone 20
What's the story
Apple's upcoming 20th-anniversary iPhone is rumored to debut in 2027 with a unique curved-glass design and solid-state buttons. These innovative features were recently highlighted by popular leaker Instant Digital on Weibo. The post detailed several expected specifications for the special edition device, including the much-discussed solid-state button technology.
Button innovation
Solid-state buttons
Solid-state buttons work by detecting pressure changes, like a finger touching the edge of a device, instead of using mechanical or capacitive systems. This allows manufacturers to design devices with uninterrupted surfaces that don't require physical buttons. The leaker claimed that Apple is testing this feature in different scenarios such as with gloves on, wet hands, extreme temperatures, and through cases.
Chip technology
Ultra-low power chip to back functioning of solid-state buttons
The solid-state button's operation will be aided by an "ultra-low power chip" that can detect its use even when the iPhone is off. This tech was first hinted at by the leaker in October 2025, when Apple had reportedly completed the "functional verification" of its solid-state button system. The feature could also pave the way for an all-glass iPhone model, enhancing its aesthetic appeal.
Additional specs
Other expected features
Along with the solid-state buttons, the leaker also hinted at an under-display Face ID system and an under-display front camera for the 20th-anniversary iPhone. The device is also expected to sport a dual-layer OLED screen similar to that of iPad Pro display panels. For power, it could pack a battery with around 6,000mAh capacity and support reverse wireless charging.
Display durability
New Ceramic Shield Ultra screen protection is also rumored
The leaker also hinted at a new front display glass dubbed "Ceramic Shield Ultra," which is said to be scratch-resistant even when kept in a pocket with keys. This speculation isn't far-fetched as Apple regularly upgrades the protective glass on its flagship products. However, it's worth noting that Weibo leakers aren't always accurate and often recycle rumors from other sources without proper analysis or fact-checking.
