iOS 27.3 Is Bringing 10 New Features to Your iPhone

Apple is testing iOS 27.3, and the upcoming update could bring more than routine bug fixes. The first developer beta introduces several new features across Siri, Safari, Health, Fitness+, and StandBy.

The update is still in beta, so Apple could change or remove features before the public release. Here are 10 additions worth watching.

1. Siri Can Perform More Actions Inside Apps

Siri is becoming more useful with expanded app controls. You can ask it to organize files, create calendar events, manage Safari tabs, edit photos, schedule messages, and create Apple Music playlists.

The expanded capabilities cover several Apple apps, including Messages, Photos, Mail, Notes, Maps, and Reminders. Apple is also opening the door for third-party developers to add their own Siri actions.

2. A Redesigned Health App

Apple is bringing back its redesigned Health app in the iOS 27.3 beta. The updated experience introduces new sections for health insights and longevity tracking.

One notable addition is Health Age, which compares selected health measurements with your actual age. Some insights use information such as heart rate, sleep, activity, and other available health data.

3. New Gym Strength Plans in Fitness+

Apple Fitness+ is testing a new Gym Strength feature. It creates personalized four-week strength-training plans based on your goals, experience, schedule, and available equipment.

The plans also include exercise demonstrations and recommendations to help users follow their routines.

4. Vertical Tabs Arrive in Safari

Safari is getting a feature that many desktop browser users already appreciate: vertical tabs.

Instead of displaying open tabs across the top, Safari can show them in a sidebar. This makes it easier to manage multiple websites, particularly on larger displays.

5. Safari Gets Adaptive Dark Mode

Another useful Safari addition is Adaptive Dark Mode. It can automatically apply a dark appearance to websites that don’t offer their own dark theme.

This could make browsing more comfortable at night without requiring a separate browser extension.

6. StandBy Mode Gets More Customization

Apple is testing additional StandBy options, including updated analog and digital clock faces, new Calendar and Weather views, and more customization.

Users can also create multiple versions of certain views and switch between them. The Photos view can use images from Shared Albums.

7. Reachability Comes to iPhone Duo

Apple is testing a new Reachability option for its iPhone Duo. The feature is designed to make the wide outer display easier to use with one hand by shifting content toward the side where your thumb can reach it.

This is a device-specific addition rather than a feature for every iPhone.

8. Siri AI Supports More Languages

Siri AI is expanding its language support with Traditional Chinese, Vietnamese, Turkish, and Norwegian.

This could make Apple’s newer AI capabilities accessible to more users, although availability may depend on device compatibility, language settings, and region.

9. Live Rewind and Siri Recap for Apple Watch

Apple is also testing two Audio Intelligence features for compatible Apple Watch models: Live Rewind and Siri Recap.

Live Rewind can show a transcript of a recent conversation, while Siri Recap provides a summary of conversations. These features are being tested through watchOS 27.3 and require the corresponding iPhone software.

10. Siri Mode Comes to iPad Camera

iPadOS 27.3 is testing Siri Mode in the Camera app on compatible iPads. The feature lets users ask Siri about their surroundings using the camera, extending Apple’s visual intelligence experience beyond the iPhone.

Final Takeaway

iOS 27.3 looks like a feature-focused update rather than a simple maintenance release. Expanded Siri capabilities, Safari improvements, a redesigned Health app, and new Fitness+ plans are among the most interesting additions.

For now, these features are part of beta testing. If you prefer a stable iPhone experience, it’s best to wait for Apple’s public release instead of installing an early developer beta.

Note: Features and availability may change before the final release. Some additions require compatible devices, software versions, or regional support.
