Apple Watch Blood Oxygen Feature Returns to U.S. Following Software Update
The blood oxygen detection feature for certain Apple Watch models is set to return to the U.S. market, according to an update from Apple. The company will re-enable the functionality for select users via an upcoming software update for the iPhone and Apple Watch.
The feature, which was previously disabled in the U.S. on new Apple Watch Series 9 and Apple Watch Ultra 2 models due to a patent dispute, is now being reintroduced. A recent U.S. Customs ruling and a new software design enable the updated version of the feature.
Apple Watch Series 9, Apple Watch Series 10, and Apple Watch Ultra 2 users in the U.S. who currently do not have the feature will be able to access it by updating their devices. This requires updating a paired iPhone to iOS 18.6.1 and the Apple Watch to watchOS 11.6.1. The redesigned feature will now measure sensor data on the Apple Watch but perform the calculation on the paired iPhone, with results viewable in the Health app.
The company has stated that this update will not affect previously purchased Apple Watch units that included the original blood oxygen feature, nor will it impact units sold outside of the U.S.
In its statement, Apple reaffirmed its commitment to providing a wide range of health and wellness tools to its users. In addition to blood oxygen monitoring, the latest Apple Watch models offer features such as irregular rhythm notifications, an ECG app, sleep apnea notifications, and fall detection, among others. The company emphasised its dedication to creating features that are grounded in science and prioritise user privacy.
