iOS 27 Beta 4 Introduces Smarter Features, Better Performance, and New Customization Options
Apple has released iOS 27 Beta 4, giving developers and public beta testers another preview of what's coming later this year. While this update doesn't completely reinvent the iPhone experience, it delivers several meaningful improvements that make everyday tasks smoother and more customizable.
From better offline entertainment and camera upgrades to Siri refinements and performance enhancements, here's everything new in the latest iOS 27 beta.
Apple TV Gets Smarter Offline Downloads
One of the most practical additions in iOS 27 Beta 4 arrives in the Apple TV app.
A new Automatic Downloads setting lets the app download upcoming episodes of shows you're watching. Once you've finished an episode, the app can automatically remove it to free up storage space.
This feature is especially useful for travelers or anyone who regularly watches content without an internet connection.
Photos App Adds a More Immersive Viewing Mode
Apple has also updated the Photos app with a new Zoom Photos to Fill option.
When enabled, images automatically expand to fill the display for a more immersive viewing experience. Users who prefer seeing photos in their original proportions can simply turn the feature off in Settings.
The update gives people more control over how they browse their photo collections without changing the original images.
Managing Photos and Files Gets Easier After Switching Devices
Many users explore new iOS features after upgrading to a new iPhone, which often means moving years of photos, videos, and personal files.
A tool like Smart Transfer can simplify that process by helping users organize content before or after migrating to a new device. Beyond moving data, it includes a built-in photo gallery manager that helps sort images and reduce clutter. The app also features a speed test app to quickly check network performance before large transfers, making file migration more reliable.
For users who frequently exchange files between devices, Smart Transfer also supports share me file sharing, allowing photos, videos, and documents to be shared quickly without relying entirely on cloud storage.
Siri Gets More Flexible
Apple continues refining Siri with several welcome improvements.
The latest beta introduces:
A redesigned voice selection screen
Adjustable response preview length
Live transcription for voice requests
Updated onboarding screens explaining new Siri capabilities
These additions make Siri easier to personalize while improving accessibility for users who prefer reading responses instead of listening to them.
ProRes Log 2 Arrives for Advanced Video Recording
Content creators have another reason to be excited.
iOS 27 Beta 4 introduces ProRes Log 2, giving compatible iPhones improved dynamic range and more flexibility during color grading.
Professional videographers and creators who edit footage after recording should benefit the most from this upgrade, as it provides more control during post-production.
Better Wi-Fi Controls
Apple has also fine-tuned Wi-Fi management.
Instead of applying Connectivity Assist globally, users can now enable or disable the feature for individual Wi-Fi networks. This offers greater flexibility when switching between home, office, or public internet connections.
It's a small update, but one that can improve everyday reliability.
AirPods Receive Easier Adaptive Audio Controls
Adaptive Audio settings are now easier to access directly from Control Center.
The updated interface allows users to quickly adjust how AirPods respond to changing environments, making it simpler to personalize listening preferences throughout the day.
Apple Removes a Beta 3 Visual Feature
Not every change in Beta 4 adds something new.
Apple has removed the wallpaper cutout effect introduced in the previous beta release. While some users appreciated the visual enhancement, the company appears to be focusing more on stability and overall performance before the public launch.
Beta Code Hints at a Foldable iPhone
One of the most interesting discoveries isn't visible in the interface at all.
Developers found code referencing multiple internal batteries, fueling speculation that Apple is preparing software support for its long-rumored foldable iPhone.
Although Apple hasn't confirmed any new hardware, dual batteries would make sense for a foldable device where power components are split between two sections of the phone.
General Performance and Stability Improvements
As expected, iOS 27 Beta 4 also includes numerous behind-the-scenes improvements.
Apple continues refining system stability, reducing bugs, and optimizing overall responsiveness ahead of the final release later this year. While many of these enhancements aren't immediately noticeable, they contribute to a smoother day-to-day experience.
Final Thoughts
iOS 27 Beta 4 focuses less on flashy additions and more on meaningful improvements that enhance everyday usability. Smarter downloads, better photo viewing, expanded Siri customization, improved camera capabilities, and more flexible network controls all help polish the overall experience.
Combined with ongoing performance refinements and hints about Apple's future hardware plans, this beta offers another encouraging glimpse at what users can expect when iOS 27 officially launches later this year.
