Apple released software updates for iPhone and Apple Watch devices that restore a previously disabled health feature. The iOS 18.6.1 and watchOS 11.6.1 updates bring back Blood Oxygen Monitoring capabilities for United States users. This feature disappeared from American devices during 2024 after legal disputes with health technology company Masimo over patent rights. Users can download these updates through their device settings by navigating to the software update section. The installation process requires adequate battery life and proximity between paired devices.
The restored Blood Oxygen Monitoring operates differently from its original version. Apple Watch devices collect blood oxygen data but transfer measurements to paired iPhones for processing. Users access their readings through the Health application's Respiratory section rather than directly on their wearable device. This modified approach allows Apple to circumvent ongoing patent restrictions while maintaining functionality. The company has not announced additional features or improvements within these particular software releases.
