Blood Oxygen Meter on Apple Watch Can Be Reactivated After iPhone Jailbreak

The blood oxygen measurement feature on Apple Watch can be reactivated through jailbreaking

The ongoing legal battle between Apple and health technology company Masimo has revealed a detail: apparently, jailbreaking an iPhone can reactivate the blood oxygen measurement function on an Apple Watch.

Jailbreaking: A Possible Solution

Jailbreaking is a process that allows iPhone users to bypass the restrictions imposed by Apple on the operating system, offering a new level of personalisation and control over the device. Now, it seems that the same process may resolve the problem of blocked blood oxygen measurement on Apple Watch.

The Battle Over Blood Oxygen Measurement

Apple and Masimo are in a legal battle due to Apple's alleged patent infringement, specifically regarding blood oxygen monitoring technology that had been patented by Masimo. Consequently, Apple was forced to disable this function on its Apple Watch in the US. According to the report, even if Apple is unsuccessful in its appeal against the import ban, the company will be able to reactivate the blood oxygen measurement function by August 2028 at the latest, when Masimo's patent expires. Thus, until the dispute is resolved or the patent expires, users who wish to access the blood oxygen measurement function on their Apple Watch may need to consider jailbreaking as a potential solution. However, it's worth noting that jailbreaking can void the device's warranty and potentially expose it to security vulnerabilities. Therefore, it is advisable that users carefully weigh the pros and cons before going down this path. Made with AI. Source: Ben Lovejoy Reviewed by:
