If you thought the updates for iOS 18 concluded with the recent release of iOS 18.6, think again. Apple has introduced a significant update with iOS 18.6.1, aimed specifically at restoring a vital feature for millions of Apple Watch users. In this article, we'll delve into the key elements of the update, including its compatibility, features, and initial user feedback. Stay tuned for updates as we’ll provide a comprehensive assessment on Friday, August 8.
iOS 18.6.1 is compatible with all iPhones released from 2018 onwards. This includes models such as the iPhone XS, iPhone XS Plus, and iPhone XR, as well as every subsequent model like the iPhone 11 series, iPhone 12, iPhone 13, and iPhone 16 series. Additionally, the update supports the second- and third-generation iPhone SE models and the iPhone 16e. If you own any of these devices (excluding the first three models), you're good to go with iOS 18.6.1.
To update your iPhone, simply navigate to the Settings app, tap on General, and then select Software Update. From there, choose Download and Install. The update size is approximately 720MB, making it a medium download, but the installation process should be relatively quick.
This update is particularly important for Apple Watch users as it reintroduces a feature that had been disabled due to a legal dispute between Apple and medical equipment company Masimo. The blood oxygen monitoring feature, which was unavailable on the Apple Watch Series 9 and Apple Watch Ultra 2 sold in the U.S., is now back in action. It also did not appear on Apple Watch Series 10 models sold in the States.
To utilize the blood oxygen monitoring feature again, users will need to install both the iOS 18.6.1 and watchOS 11.6.1 updates. The update allows the Blood Oxygen app on compatible Apple Watches to transmit data to the iPhone, where it is calculated and accessed within the Health app under the Respiratory section. Compatible models include the Apple Watch Series 7, Series 8, Series 9, Apple Watch Ultra, and Apple Watch Ultra 2.
While iOS 18.6.1 does not introduce any new security features, it follows closely on the heels of a prior update that included over 20 security enhancements. Given that the previous update was released just two weeks ago, the lack of new security features in this version is not unexpected.
Initial reactions from users have been generally positive, with many reporting improved performance on their iPhones. However, no significant issues have been widely reported; one user mentioned encountering a blank screen on their iPad, although it’s important to note that there was no iPad update associated with this release.
If you reside in the U.S. and own an Apple Watch, updating to iOS 18.6.1 is highly recommended. For others, this update poses no risks and could potentially enhance your iPhone's performance. Don’t forget to install watchOS 11.6.1 if you have an Apple Watch to fully enjoy the benefits of this update. Look out for our final verdict next week as we continue to monitor user feedback and performance.
