Starting Monday, September 14, Apple will officially roll out iOS 27 to all compatible iPhones. The update arrives first in the morning Pacific (around 10 a.m.) and early afternoon Eastern (around 1 p.m.) via Settings → General → Software Update. This year’s upgrade delivers sweeping interface tweaks, smarter AI, and changes to how your iPhone moves and operates. Below are the biggest new additions.
Top New Features
Siri AI becomes a full-scale, generative assistant. Powered by Apple Intelligence, it can tap into your device’s data, understand context on screen, and handle a wide range of tasks. It’s available through the new dedicated Siri app or by holding the side button—but it requires an iPhone 15 Pro or newer. Siri AI launches in English only for now and starts with usage limits; continued access may cost extra in future updates. EU users won’t get it at launch due to regulatory delays.
Expanded Apple Intelligence tools enhance content, creativity, and easy automation. Among the new additions are “Extend” and “Reframe” tools in Photos, photorealistic image creation in Image Playground, natural-language shortcuts in Shortcuts, and video descriptions generated automatically for HomeKit Secure Video cameras.
Liquid Glass design refinement brings sharper, higher-contrast visuals. App icons and UI elements get more detail. A new slider lets users adjust the clarity or tint of the Liquid Glass effect to their taste.
Performance gains are promised across the board. Apple says apps will launch up to 30% faster, newly added photos in the Photos library load up to 70% more quickly, and AirDrop transfers improve by up to 80%. Various other speed and responsiveness updates are included.
iPhone Handoff lets you share a single phone number across two phones. For example, you could use both phones—and receive calls or messages—under the same number. Support from carriers is required; T-Mobile in the U.S. and Deutsche Telekom in Germany are among the first, with T-Mobile charging $5/month.
Apple Cash Bill Splitting is now native. In the U.S., you can split a tab or receipt via Wallet or Messages. Even more casually: point your iPhone at a receipt in Siri mode (using the camera), and the system can suggest splitting the bill, dividing items, plus tax and tip. Settlements are handled via Apple Cash.
Find My gains finer privacy control. Gone are the limited preset options—you’ll be able to share your location for custom durations (for example, four days and six hours), or set specific expiration times. You can also temporarily hide your location from particular people until end of day without alerting them.
CarPlay welcomes video content when parked. In compatible vehicles, you’ll now find video apps in CarPlay—letting you browse for and play videos when the car is stationary. Developers can build apps for video browsing in CarPlay, and if the iPhone app supports AirPlay video, you can stream to the vehicle’s display via CarPlay’s interface.
Compatibility & Roll-out Notes
iOS 27 supports a wide range of devices—going all the way back to iPhone 11 models. However, some features like Siri AI and other Apple Intelligence-driven tools require the newer hardware of iPhone 15 Pro or later. Notably, the launch of certain features is regional: Siri AI won’t be available in the EU initially. Carriers may charge for new services like iPhone Handoff.
Apple revealed more than 250 changes and additions across its platforms earlier this year. This update focuses on refining the user interface, infusing more intelligence through AI tools, boosting performance, and expanding privacy and sharing controls.
Why this matters: iOS 27 marks a turning point in Apple’s software strategy—shifting from incremental feature additions to deeper integration of intelligence and smoothing the visual experience. The move to make Siri generative—and tying it to newer devices—signals Apple doubling down on AI while managing its hardware limitations. As users begin updating, performance improvements, especially on older phones, and how well features like Siri AI perform outside the U.S. and EU will be key to watch. If all goes well, iOS 27 should feel like a leap, not just another version.
