Apple is rolling out iOS 27, bringing a massive wave of upgrades headlined by a completely overhauled, conversational assistant known as Siri AI.

Available for download via the Settings app, the update requires an iPhone 11 series or newer, though advanced Apple Intelligence features demand an iPhone 15 Pro or later. Here is a breakdown of the major changes coming to your device.

What Happened: The Siri AI Revolution

The standout feature in iOS 27 is Siri AI, a ChatGPT-like personal assistant designed to handle complex multi-step requests. Unlike older iterations, Siri AI features on-screen awareness, pulls from your personal on-device data, and integrates tightly with apps.

Apple has also refined the Liquid Glass interface first introduced in iOS 26. Users will notice sharper app icons, improved contrast, and a new slider to adjust the clarity or tint of the interface elements.

Performance Boosts and New Tools

Beyond aesthetics and AI, Apple focused heavily on speed. Across the board, iOS 27 delivers up to 30% faster app launches, 70% faster photo loading in the library, and up to 80% faster AirDrop transfers.

The update also introduces several practical additions:

  • iPhone Handoff: Allows users to seamlessly switch between two iPhones using the same phone number (initially supported by carriers like T-Mobile).
  • Smart Bill Splitting: Powered by Apple Cash and Apple Intelligence, the Camera app's new Siri mode can scan receipts to automatically calculate individual totals, tips, and taxes.
  • Flexible Find My Sharing: Location sharing can now be scheduled to expire at a precise date and time, or temporarily paused without notifying specific contacts.
  • CarPlay Video: Parked vehicles supporting AirPlay can now stream video, with new developer tools allowing direct video browsing on the car's display.

Important Context & Limitations

While the global rollout begins today, some features come with immediate caveats. Siri AI is initially limited to English, subject to daily usage limits, and unavailable in the European Union due to ongoing regulatory hurdles with the European Commission. Additionally, carriers may charge extra monthly fees for features like iPhone Handoff.

If your device is compatible, head to Settings > General > Software Update to install the update and explore the new capabilities firsthand.
