Apple has released iOS 26 Beta 7, the latest test version for iPhones, and it comes with a few exciting changes. While this update is not a major redesign, it adds useful features, fixes bugs, and makes the system more stable before the final launch. If you are testing iOS 26 on your iPhone, here’s a simple breakdown of what’s new in Beta 7.
Blood Oxygen Measurement is Back
One of the most important updates in iOS 26 Beta 7 is the return of Blood Oxygen tracking for Apple Watch users in the U.S.
-
This feature was disabled last year due to legal issues, but Apple has now found a way to bring it back.
-
Instead of processing data on the watch, the calculations are now done on the iPhone, and results appear in the Health app under the Respiratory section.
-
This is great news for fitness and health-focused users who depend on oxygen level data.
Adaptive Power Notifications
Apple also added a new notification option for Adaptive Power mode.
-
When your iPhone automatically lowers performance to save battery, you’ll now receive a notification.
-
This feature is especially helpful because you’ll know exactly when iOS is slowing down the device to extend battery life.
-
It works best on iPhone 15 Pro models and newer, though the update is available for iPhone 11 and later.
Liquid Glass Design Tweaks
The new Liquid Glass design continues to get small improvements:
-
The Control Center background is now darker, making icons and text easier to read.
-
A screenshot issue where images looked darker than they should has been fixed.
These small changes make iOS 26 look more polished and easier to use.
Bug Fixes and Stability
As with most late beta versions, iOS 26 Beta 7 also improves overall stability.
-
Apps run smoother, and crashes are less common.
-
Performance across the system feels faster and more consistent.
-
Apple Intelligence features work better compared to earlier betas.
Final Thoughts
iOS 26 Beta 7 focuses on health, battery management, and design polish. With Blood Oxygen tracking back, new battery notifications, and better performance, this update shows Apple is preparing for a strong official release.
