iOS 26.4 Beta: Apple’s Latest Update Packs Surprising New Features

Apple has just dropped the iOS 26.4 beta, and it’s loaded with both major improvements and subtle tweaks that could change how you use your iPhone daily. From smarter sleep tracking to innovative audio features, here’s everything you need to know about this incremental yet impactful update.

Sleep Tracking Gets Smarter

The Health app receives a notable upgrade with the introduction of an Average Bedtime metric. This new feature provides users with a clearer picture of how their bedtime habits affect sleep quality. By tracking when you typically go to bed, Apple aims to help users establish more consistent sleep patterns, which research shows is crucial for overall health and wellbeing.

Vitals App Enhancement

Apple has quietly upgraded the Vitals section in the Health app for U.S. users. The most significant change is the addition of blood oxygen level readings directly on the daily line graph overview. Previously, blood oxygen data existed in a separate section without graph integration, making it harder to correlate with other health metrics. This integration allows for better trend analysis and health monitoring.

Revolutionary Audio Zoom Feature

One of the most exciting additions is Audio Zoom in the Camera app. When recording video, this feature automatically focuses the audio on your subject as you zoom in, creating a more professional and immersive recording experience. Whether you’re filming a concert, a speech, or your child’s soccer game, this feature ensures the sound quality matches the visual focus of your shot. Users can toggle this feature on or off in the Camera settings, giving full control over their audio preferences.

CarPlay Gets an Entertainment Upgrade

Leaked code suggests Apple is preparing to bring Apple TV support to CarPlay. This means passengers (when the vehicle is parked or not in motion) could soon stream their favorite shows and movies directly through the car’s dashboard display. This feature, announced at WWDC 2025, represents Apple’s push to make CarPlay more than just a navigation and music platform.

Apple Music Multi-Playlist Feature

Music lovers will appreciate the new ability to add songs to multiple playlists simultaneously in Apple Music. The updated interface includes a list button that allows users to select multiple playlists at once, eliminating the tedious process of adding the same song to different collections one at a time. This small but significant improvement streamlines music organization for power users.

Hotspot Data Transparency

Apple has relocated hotspot data usage information, moving it from the Cellular section directly into the Personal Hotspot settings. This change makes it immediately visible how much data you’ve consumed while tethering, helping users avoid unexpected overage charges and better manage their mobile data usage.

Live Captions Expansion

Accessibility continues to be a priority with the addition of Chinese (Taiwan) as a new language option for Live Captions. This expansion makes real-time captioning more accessible to millions of additional users, breaking down language barriers in communication.

Subtle UI Refinements

Several minor but noticeable changes enhance the user experience. The passcode entry screen now features center-aligned text instead of left-aligned, creating a more balanced and modern appearance. Additionally, the Shortcuts app gains a new Set Charge Limit action, allowing users to program battery charge limits for their iPhone—a feature particularly useful for preserving long-term battery health.

What This Means for Users

While iOS 26.4 may seem like a minor update compared to major annual releases, these refinements demonstrate Apple’s commitment to continuous improvement. The combination of health tracking enhancements, creative tools for content creators, and accessibility expansions shows Apple is listening to user feedback and addressing specific pain points.

The update is currently available to developers in beta form, with a public beta expected soon. As with all beta software, users should exercise caution before installing on primary devices.

iOS 26.4 represents Apple’s philosophy of iterative improvement—small changes that collectively enhance the user experience without disrupting familiarity. From better sleep insights to smarter audio recording, this update proves that sometimes the most impactful innovations come in modest packages.
