Apple is preparing a major firmware update for its mobile devices — iOS 27.3. According to reports, the first beta version has already been shared with developers for testing, and a global release for all iPhone and iPad users is expected by mid-December 2026. The update combines several major focus areas: from a deep overhaul of the Siri AI personal assistant to new tools for health, the Safari browser, and tablets. Below is a breakdown of the key changes confirmed in the beta and described in available materials.
Siri AI goes beyond simple commands
The centerpiece of iOS 27.3 is a significant strengthening of Siri AI's role in daily tasks. The assistant has learned to perform more complex, multi-level operations within 15 classic applications: Calendar, Files, Journal, Mail, Maps, Messages, Music, Notes, Photos, Preview, Reminders, Safari, Shortcuts, and Weather. In practice, this means complex requests: creating curated playlists in Music, grouping tabs in the browser, or automatically scheduling messages in Messages. It is specifically noted that the AI independently selects the best photos in the gallery and generates new notes or journal entries without the need to touch the screen. Related reports also indicate that Apple is expanding the assistant's capabilities to interact with third-party services — for example, booking a taxi, changing addresses, or scheduling services.
Health app reoriented towards well-being
The new Health app interface is reoriented toward the user's general well-being and divided into three key sections: Insights, Longevity, and Browse. In the Insights tab, users receive a detailed analysis of sleep metrics, daily readiness for exercise, and overall activity. The Longevity section estimates the body's biological age based on daily activity, VO2 max metrics, and sleep quality. Furthermore, the updated application has received expanded language support, making it more accessible to a global audience.
Safari: Vertical tabs and adaptive dark mode
The Safari browser in the new update has received a number of improvements for a more convenient web experience. Notable new features include vertical tabs, which allow for more effective management of a large number of open pages on tablet and computer screens. Another important feature is the adaptive dark mode, which automatically applies a dark look even to web pages that do not have native support for this format. Deep integration with Siri AI further allows for managing browsing history, sorting tabs, and tidying up the browser workspace with simple text commands.
StandBy, iPhone Duo, and an 'on-screen home hub'
The previously exclusive iPhone Duo feature now extends to all supported iPhone models. As part of the update, Apple is completely rethinking the StandBy mode: users are offered new analog and digital clock options, as well as expanded visual widgets for the Calendar and Weather apps. With shared photo albums and several watch face variations for quick switching, every smartphone effectively transforms into a full-fledged 'smart' home hub.
iPad: Visual Intelligence via camera and Apple Pencil
Apple tablets have gained new capabilities through the integration of Visual Intelligence with the camera. Using AI, users can ask questions about objects in front of the lens in natural language and receive answers. The feature recognizes landmarks, helps find similar products in online stores, and provides information about concerts and other events via posters. Apple Pencil support makes searching even more convenient: the stylus can be used to highlight a specific object on the screen to receive detailed information. The sum of these changes highlights Apple's strategy to turn AI into an overarching layer that operates across applications, the camera, and device interfaces.
