iOS 27 Beta 4 - All New Features and Changes (2026)

The iOS 27 Beta 4 update brings a handful of new features and improvements to Apple's mobile operating system, offering a sneak peek into what iPhone users can expect when the full release hits in September. While it's a minor update, it's a crucial step in Apple's ongoing efforts to refine iOS and prepare it for the generative AI era. Here's a breakdown of the key changes, along with my thoughts and insights.

TV App: Automatic Downloads

One of the more noticeable additions is the new Automatic Downloads toggle in the Settings section of the Apple TV app. This feature automatically downloads the next two episodes of shows you start watching in the 'Continue Watching' section. It's a handy feature for those who want to binge-watch without worrying about running out of storage or missing the next episode. However, I'm curious to see how this impacts the user experience, especially in terms of data usage and storage management.

Photos: Zoom Photos to Fill

The Photos app introduces a 'Zoom Photos to Fill' toggle, which slightly zooms photos that nearly match the screen's aspect ratio. This is a subtle but useful feature, especially for those who want to fill the screen with their photos without cropping them. I appreciate the attention to detail here, as it enhances the visual appeal of the photos and makes the viewing experience more immersive.

Wallpaper: Gone but Not Forgotten

The wallpaper feature, which was introduced in beta 3, has been removed in this update. It allowed users to see a cutout of the subject of their wallpaper on the Home Screen when swiping. While it was a unique and visually appealing feature, I understand Apple's decision to remove it. Perhaps it was causing more issues than it was worth, or it might have been a temporary experiment. It's a reminder that not all features make the final cut.

Siri Voices and Customization

The Siri Voice selection interface has been updated, with a new look and more options. Devices without customizable voice options now have a dedicated section for selecting voices and accents. On the other hand, devices with custom Siri selections offer more voice options, which is a welcome improvement. However, I'm curious about the implications of this change, especially for users who want to personalize their Siri experience further.

Siri Settings: Previews and Transcription

The Siri section of the Settings app now includes a new option to adjust the length of previews in the Siri app. Users can choose up to five lines or none, giving them more control over the information they receive. Additionally, the 'Always Show Request' toggle in the Accessibility settings shows a transcription of what you say to Siri on the screen, which is a useful feature for those who want to review their commands.

ProRes Log Format and Camera

The Camera app introduces an option to choose a ProRes log format when Apple ProRes is enabled. Users can select 'Log' or 'Log 2', with the latter being the latest format that retains more information for additional flexibility in editing color and making adjustments. This is a significant addition for professional photographers and videographers, and I'm intrigued by the potential impact on content creation and post-production.

Wi-Fi Assist: Customizable Connectivity

iOS 27 Beta 4 adds the ability to enable or disable Connectivity Assist for each Wi-Fi network, regardless of the master toggle setting. This gives users more control over their network connectivity, allowing them to optimize their experience based on their specific needs. It's a small but significant change that demonstrates Apple's commitment to providing a customizable and flexible user experience.

Dual Battery iPhone References

The code in the fourth beta of iOS 27 references an iPhone with two batteries, which could be a hint at the rumored foldable iPhone Ultra. The strings like 'The batteries in this iPhone are performing as expected' suggest that Apple is preparing for a dual-battery design. This is an exciting development, as it could revolutionize the smartphone form factor and offer new possibilities for battery life and performance.

Conclusion: A Sneak Peek into the Future

iOS 27 Beta 4 provides a glimpse into the future of Apple's mobile operating system, showcasing a mix of subtle improvements and intriguing new features. From the Automatic Downloads in the TV app to the customizable Wi-Fi Assist and the ProRes log format in the Camera app, each change adds value to the user experience. As we approach the September release, I'm eager to see how these features evolve and how they contribute to the overall refinement of iOS.

In my opinion, Apple is doing a great job of balancing innovation and stability, ensuring that iOS remains a powerful and user-friendly platform. The inclusion of context-aware Siri and other AI-related features hints at a future where iOS becomes even more intelligent and intuitive. As an iPhone user, I'm excited to see how these updates shape the overall user experience and look forward to the full release of iOS 27.
