Apple releases iOS 27.3 beta 1 with major new features across Siri AI and Safari, and this is everything that’s been added

Apple has rolled out a substantial software update that could change how people use their iPhones on a daily basis.

The first iOS 27.3 beta introduces new features, including a major expansion of Siri AI and several long-awaited Safari improvements.

It also brings changes to Apple Music, the Health app, and how people interact with their devices.

Here’s a closer look at everything Apple has added and what iPhone users can expect.

1. Siri AI can now perform more actions

Siri can now carry out more complicated tasks across Apple’s built-in apps on its gadgets, including scheduling text messages, unsending messages, and unsubscribing from promotional emails.

It can also perform additional actions in apps such as Calendar, Files, Maps, Messages and Mail.

2. Third-party apps can integrate with Siri AI

Apple is introducing App Intents for third-party developers, allowing their applications to bring content and actions directly into Siri AI.

This could eventually let users ask Siri to check deliveries, book reservations or place orders without manually opening individual applications.

3. Siri is getting a new Skills feature

Apple is introducing Skills to help Siri combine several actions into a single experience when handling more complicated requests.

Developers will be able to use this functionality to create more advanced interactions that respond to everyday language.

4. Siri AI supports more languages

The latest update expands Siri AI’s language support to include Traditional Chinese, Vietnamese, Turkish, and Norwegian.

This should make Apple’s upgraded assistant accessible to a wider range of users around the world.

5. Safari gets adaptive dark mode

Safari can now automatically apply a dark appearance to websites that do not offer their own dark mode.

Users can enable or disable the feature through Safari’s settings, although Apple warns that some website elements may have lower contrast.

6. Safari introduces vertical tabs

Apple has finally added vertical tabs, allowing users to display their open browser tabs vertically rather than in the traditional horizontal layout.

Users can also choose whether tabs appear at the top or bottom of the screen through Safari’s settings.

7. Siri can organize Safari tabs

Siri AI can now perform actions directly on open Safari tabs, including moving, sorting, organizing, and closing them.

This gives users another way to manage their browsing sessions without manually navigating through every open page.

8. The redesigned Health app returns

Apple has brought back its redesigned Health app.

It was included in the iOS 27.2 beta but removed before that update’s final release.

The updated interface includes redesigned dashboards for sleep, fitness, heart rate, vital signs and other health information.

9. Health app introduces Healthy Age

One of the most interesting additions is Healthy Age, which gives users a new way to understand how their health compares with typical measurements for their actual age.

The redesigned Longevity section also includes assessments that users can complete to help improve their scores.

10. Apple introduces a new Gym Strength experience

Apple’s new Gym Strength feature includes more than 350 exercises and allows users to build personalized four-week workout plans.

They can choose their fitness goals, available equipment, preferred trainers and training days to create a routine that suits them.

11. Apple Music finally gets full landscape mode

Users can now navigate the entire Apple Music application in landscape orientation rather than being restricted to the Now Playing screen.

This means they can browse their libraries, explore new music and navigate different sections while holding their iPhone horizontally.

12. StandBy mode comes to standard iPhones

Apple is bringing the more advanced StandBy experience previously introduced on the iPhone Duo to standard iPhone models.

Users can access additional clock faces, weather and calendar displays, alongside customization options for complications and colors.

13. The App Library gets more Liquid Glass

The App Library has received further Liquid Glass styling, including a more translucent appearance around its search interface.

Apple has also adjusted the opacity of certain letters and introduced a new Liquid Glass-style search button.

14. Wallpaper customization gets a visual refresh

Apple has updated the wallpaper pairing interface with a Liquid Glass design that better matches the rest of the operating system.

The change gives the set-as-wallpaper option a more consistent appearance.

15. The iPhone Duo gets improved Reachability

Reachability is now available on the iPhone Duo, making it easier to operate the device with one hand.

Rather than simply lowering the screen, the feature shifts its contents toward the left or right depending on which hand the user is using.

16. The iPhone keyboard gets a subtle redesign

Apple has slightly adjusted the spacing around individual keyboard keys in iOS 27.3, giving them more padding at the top.

YouTuber Brandon Butch says the change makes typing feel more comfortable, particularly on the iPhone Duo’s smaller front display.

When will iOS 27.3 be released?

The first iOS 27.3 beta is available to registered developers, with public beta testing expected to follow.

The full release is anticipated during the first half of December, while a smaller iOS 27.2.1 update is also expected to bring security patches and bug fixes beforehand.

So, it looks like we’ll be getting iOS 27.3 as an early Christmas present!
