Siri AI beta design reveals hints about smaller Dynamic Island coming to iPhone 18 Pro

Apple's Siri AI beta in iOS 27 has dropped a major design clue about the upcoming iPhone 18 Pro. The AI assistant appears as a spherical orb on iPad and Mac, but takes an unusual oval shape on current iPhones—a discrepancy that strongly suggests Apple is preparing for a significantly smaller Dynamic Island on its next flagship phones.

Siri AI Design Reveals iPhone 18 Pro Hardware Clues

Apple's iOS 27 beta has inadvertently confirmed what many have suspected: the iPhone 18 Pro is getting a smaller Dynamic Island. The evidence comes from an unusual design choice in Siri AI, which appears differently across Apple devices in ways that suggest hardware design changes are coming this fall.

Users testing the iOS 27 beta have noticed that Siri AI takes on distinct shapes depending on the device. On current iPhone models, the AI assistant displays as an elongated oval—essentially a pill shape that stretches across the width of the existing Dynamic Island. However, on iPad and Mac, Siri AI appears as a classic spherical orb, matching what appears to be Apple's intended design vision

Developer Observations Point to 35% Reduction in Dynamic Island Size

Developer Lorenzo first spotted this discrepancy and shared his insights on X, noting that "Apple designed the new Siri with the iPhone 18 Pro/Max in mind, as with the rumoured smaller Dynamic Island it's a perfect orb." This explains why the Siri AI design isn't a pill shape in iPadOS and macOS

. Pre-launch speculation suggests the Dynamic Island cutout, which houses the selfie camera and Face ID sensors, could shrink by approximately 35% compared to last year's models.

The design logic is straightforward: Apple wants the new Siri AI design to integrate seamlessly with the full width of the Dynamic Island. On current iPhones with larger cutouts, maintaining that integration requires stretching Siri into an oval. But once the smaller Dynamic Island arrives with the iPhone 18 Pro, the spherical Siri AI shape will finally appear as Apple originally intended across all devices.

What the iPhone 18 Pro Design Change Means for Users

This iPhone 18 Pro design change represents more than just aesthetic refinement. A smaller Dynamic Island means more usable screen real estate without sacrificing the Face ID technology that Apple has committed to since the iPhone X. While the iPhone 18 Pro is expected to maintain many design elements from the iPhone 17 Pro—including the full-width camera plateau and aluminum unibody—this reduction in the front-facing sensor array demonstrates Apple's continued work on miniaturizing critical components.

For those still using iPhone 17 range devices, the oval-shaped Siri AI will likely remain due to physical limitations of the larger Dynamic Island. Beta software testing has already revealed these constraints, as Apple showcased during WWDC. Beyond the smaller Dynamic Island, the iPhone 18 Pro models are also rumored to feature uniform rear glass and aluminum colors, with a Dark Cherry model expected to be the standout offering

The fact that Apple is designing software around unreleased hardware speaks to the company's integrated approach to product development. Siri AI's spherical shape on existing devices essentially serves as a preview of what iPhone 18 Pro buyers will experience this fall—a more cohesive visual experience where software and hardware align perfectly across the entire Apple ecosystem.
