Apple has released the iOS 27 public beta, allowing users to test the most anticipated features without waiting until September. This version is notably more stable than previous beta cycles, but installing it on a primary device is still not recommended, especially if you rely on health-related apps. On a secondary device or with tolerance for minor bugs, it is worth exploring.
Performance improvements across all iPhones
Under-the-hood enhancements are immediately noticeable. Animations feel snappier, apps launch up to 30% faster, and AirDrop transfers complete more quickly. Everyday tasks such as taking photos, opening the keyboard, browsing the Home Screen, and switching between Wi-Fi and cellular are more responsive. iMessage sync between devices is more accurate, failed messages are automatically retried, and network transitions are seamless. These optimizations benefit all iPhones, including older models.
Siri AI becomes a conversational assistant with personal data access
The headline feature is Siri AI, a redesigned assistant that supports back-and-forth conversations, similar to ChatGPT or Claude. Unlike other chatbots, Siri AI has private access to messages, emails, photos, and files, enabling concrete actions. It can create home automations like locking all doors at midnight, find specific documents sent by a person, delete files or messages, add recipe ingredients to a shopping list, recommend restaurants based on preferences, analyze on-screen content, and answer general questions. Activation options: wake word, swipe down to type, Siri app, or side button.

Visual Intelligence and writing with Siri AI
The Camera app gains a new Siri mode for visual intelligence, useful for obtaining nutritional information about food or splitting a bill from a receipt. Write with Siri generates text from scratch, provides feedback, changes tone and style, and can mimic your writing style by analyzing your emails and messages. The system also suggests grammar fixes automatically.

Improvements in Photos, Passwords, Safari, and Home
The Clean Up tool in Photos removes unwanted objects more convincingly, with new options to extend image borders and adjust perspective or composition. The Passwords app can now automatically change weak or compromised credentials via Safari, requiring an Apple Intelligence-compatible device. Safari allows creating custom extensions using natural language commands, such as generating a citation, setting a 3-minute timer, or turning a page into pirate speak. It also automatically organizes tabs into categories and notifies you of page changes. The Home app supports 2K and 4K recording for HomeKit Secure Video cameras, with AI-generated text descriptions and natural language video search. AI features require a 2TB iCloud+ plan at launch, while 4K streaming is free.
AirPods EQ and Shortcuts enhancements
AirPods 4, Pro 2, Pro 3, and Max 2 now feature a customizable equalizer to adjust mids, highs, and lows. The Shortcuts app becomes more approachable: just describe the desired action, and AI generates the shortcut, refinable with further natural language requests or manual editing.

To install the beta, sign up on Apple's public beta website, then go to Settings > General > Software Update and select iOS 27 Public Beta. Back up your device first to potentially downgrade to iOS 26. Remember, this is a beta version; Apple continues refining Siri AI and Apple Intelligence features.
