Workout live activities changes since updating to iOS27

The Heart Rate feature on the iPhone relies on an Apple Watch paired with the iPhone to collect and display your heart-rate data. The iPhone itself does not have a built-in sensor that continuously measures your heart rate, so without a compatible Apple Watch, heart-rate information will generally not be available automatically in the Health app.

If you do not have an Apple Watch, you may still be able to measure or record your heart rate using compatible third-party apps and accessories that use the iPhone’s camera, external sensors, or other supported devices. However, the availability and accuracy of these measurements depend on the particular app or accessory.

If you are experiencing a problem with a specific third-party app, such as heart-rate data not being recorded, displayed, or synchronized with Apple Health, check the app’s permissions and settings first. For further assistance with that particular app, contact the app developer, as they are best equipped to troubleshoot issues specific to their application.

... since updating to iOS27,

Not every issue an individual encounters on their device can be attributed to an iOS update. iOS 27 or later may have coincided with what you are experiencing, but that does not mean the issue was triggered by iOS. Coincidence in timing is not, by itself, evidence of causation.

If the update itself were the root cause, then every device running that same version of iOS would exhibit the identical problem. In such a scenario, the forums would be flooded with countless posts reporting the same malfunction, creating an unmistakable wave of complaints that no one could possibly overlook.

The absence of such widespread reports strongly indicates that the issue is not a general, system-wide problem with iOS 27 or later, but rather something specific to the individual device, its configuration, installed apps, settings, hardware, or another interacting factor.

In short: iOS 27 or later may be a coincidence in timing, but there is no basis to conclude that iOS itself triggered the problem simply because the issue appeared after the update.

Sorry, I should've clarified, Apple Watch is connected to iPhone. The screenshot was taken during workout using the Apple watch
