iOS 26 beta 7 includes new Power Mode settings with an option for Adapter Power Notifications and support for Apple's redesigned blood oxygen measurement feature in the US. macOS Tahoe onboarding video has been updated to include the MacBook notch.

Apple has released the seventh developer beta of iOS 26, which includes several notable features aimed at enhancing user experience and improving battery efficiency. One of the standout additions is the introduction of new Power Mode settings, specifically the Adaptive Power Notifications toggle. This feature aims to provide users with real-time notifications when their iPhone begins adjusting performance to extend battery life.

Additionally, iOS 26 beta 7 brings back the previously disabled blood oxygen measuring feature on Apple Watch. This capability, originally introduced in September 2020 with the Apple Watch Series 6, allows users to measure the oxygen saturation of their blood using the Blood Oxygen app. The feature has been restored following a patent dispute between Apple and medical tech company Massimo [1].

The new Adaptive Power Notifications toggle is designed to complement the existing Low Power Mode feature, which has been a part of iOS since its inception. When activated, users will receive notifications when their iPhone begins adjusting performance to help extend battery life, such as lowering the display's brightness or turning on Low Power Mode when the battery is only 20% charged. This enhancement is particularly useful for users who want to monitor their battery usage more closely and take proactive measures to conserve power.

In terms of design, iOS 26 beta 7 continues to build upon the "Liquid Glass" design language introduced in previous updates. The update includes slight adjustments to the Control Center background, making it somewhat darker than it was in previous betas. This design change is part of Apple's ongoing effort to refine the visual aesthetics of its software and provide a more intuitive user experience.

The restoration of the blood oxygen measuring feature on Apple Watch is a significant development for health-conscious users. The feature allows users to monitor their blood oxygen levels, which can be particularly useful for those with respiratory conditions. The capability is now supported on iOS 26 developer beta 7, provided that the Apple Watch is running watchOS 11.6.1 and is paired with a compatible iPhone.

In summary, iOS 26 beta 7 introduces new Power Mode settings with an option for Adaptive Power Notifications and restores the blood oxygen measuring feature on Apple Watch in the US. These updates aim to enhance user experience and improve battery efficiency, making iOS 26 a promising update for investors and financial professionals alike.
