Rather than introducing new capabilities, these updates prioritize performance refinements and bug fixes to ensure a stable launch following Apple's Fall event next week.1

Siri AI Brings Major AI Upgrade to Virtual Assistant

The centerpiece of iOS 27 is Siri AI, Apple's rebuilt assistant powered by next-generation Apple Intelligence and new Foundation Models.2

This chatbot-level upgrade enables Siri to hold back-and-forth conversational interactions, access general world knowledge, understand personal context from apps like Messages and Mail, and demonstrate onscreen awareness.3

On Vision Pro, users can place a new Siri orb anywhere in their virtual space and ask questions about anything they're viewing.3

Apple Intelligence Expands Across Ecosystem

Apple Intelligence delivers AI-driven enhancements throughout the operating system, with some capabilities running on-device while others utilize Private Cloud Compute.2

The technology now powers improvements in Photos, Safari, Passwords, Mail, Messages, Phone, Shortcuts, Home, and Wallet.5

Write with Siri enables systemwide text generation and writing feedback, while Visual Intelligence has been relocated to the Camera app with a new Siri mode.5

However, many features require Apple Intelligence compatibility, limiting full functionality to iPhone 15 Pro, iPhone 15 Pro Max, and newer models.1

Liquid Glass and Performance Improvements

Apple refined the Liquid Glass design introduced last year, adding a transparency slider that lets users adjust the look of system UI elements.2

The update includes substantial performance improvements affecting app launches, Photos loading, Camera launch in Low Power Mode, AirDrop transfers, and Wi-Fi-to-cellular transitions.2

These optimizations make everything feel faster, even on older iPhones dating back to the 2019 iPhone 11, which remains the oldest compatible device.1

For Vision Pro, visionOS 27 beta transforms panorama photos into spatial environments and introduces a new Icelandic Thórsmörk environment featuring dramatic mountains and northern lights.3
