iOS 27 Beta 4: All the New Features and Changes Explained! (2026)

The iOS 27 Beta 4 update brings a handful of new features and improvements, showcasing Apple's ongoing efforts to refine its operating system. While it may not be a major overhaul, the attention to detail is impressive. Here's a breakdown of the key changes and my thoughts on them.

TV App: Automatic Downloads

Apple introduces an automatic download feature for the TV app, allowing users to download the next two episodes of shows they start watching in the 'Continue Watching' section. This is a handy addition for those who want to watch shows without an internet connection. However, I wonder if it might be a bit too aggressive, potentially leading to accidental downloads and storage issues. A more controlled approach could be beneficial.

Photos: Zoom Photos to Fill

The Photos app now has a 'Zoom Photos to Fill' toggle, which slightly zooms photos to match the screen's aspect ratio. It's a subtle feature, but it adds a touch of visual flair to the gallery. I appreciate the attention to detail, but I also think it could be a bit overwhelming if not used sparingly.

Wallpaper: Gone but Not Forgotten

The wallpaper feature, which was introduced in beta 3, has been removed. It allowed users to see a cutout of the wallpaper subject on the Home Screen when swiping. While it was a unique addition, I understand the decision to remove it. Perhaps it was too experimental, and Apple wants to focus on more stable features.

Siri Voices: Customization and Expansion

The Siri voice selection interface has been updated, offering more options for devices without customizable voices. This is a step in the right direction, as it provides users with more control over their voice assistants. However, I'm curious about the future of Siri voices, especially with the mention of 'coming soon' for more options. Will we see a wider range of accents and languages?

Siri Settings: Previews and Transcription

The Siri settings now include an option to adjust the length of previews in the Siri app, allowing users to choose up to five lines or none. This gives users more control over their interactions. Additionally, the 'Always Show Request' toggle in Accessibility is a useful feature, showing a transcription of the user's speech. These additions enhance the overall user experience.

ProRes Log Format: Flexibility and Creativity

The Camera settings now offer an option to choose a ProRes log format when Apple ProRes is enabled. Log 2, the latest format, retains more information, providing flexibility for color adjustments and editing. This is a pro-level feature that caters to content creators and editors, showcasing Apple's commitment to professional-grade tools.

Wi-Fi Assist: Customized Connectivity

Users can now enable or disable Wi-Fi Assist for each Wi-Fi network, giving them more control over their connectivity. This is a practical addition, especially for those with multiple Wi-Fi networks. It's a small but significant improvement that demonstrates Apple's attention to user preferences.

AirPods: Adaptive Mode Enhancements

The AirPods options in Control Center have been updated, adding more choices for Adaptive mode. This is a welcome improvement, as it allows users to customize their AirPods experience further. I'm intrigued by the potential for more adaptive features in the future, especially with the ongoing advancements in audio technology.

Dual Battery iPhone References: Foldable iPhone Ultra?

The code in iOS 27 Beta 4 references an iPhone with two batteries, which could hint at the upcoming foldable iPhone Ultra. This is an exciting prospect, as a dual-battery design would provide longer battery life and more flexibility. However, I'm curious about the implications for the overall design and user experience of such a device.

In conclusion, iOS 27 Beta 4 showcases Apple's commitment to refining its operating system with thoughtful additions and improvements. From automatic downloads to ProRes log formats, each feature has its merits. However, it's also important to consider the broader implications and user experience. As an expert, I appreciate the attention to detail, but I also encourage Apple to consider user feedback and potential challenges to ensure a seamless and enjoyable experience for all iOS users.
