It might be time for a firmware update/bug fix for the Apple Watch.
A number of Apple Watch owners have reported inconsistent or inaccurate heart rate measurements while exercising, with some saying issues have continued even after receiving replacement watches from Apple, calling into question one of the wearable’s signature features.
The issue, which Apple has yet to classify or acknowledge as a widespread problem, seems to result while trying to monitor high-impact exercises. A thread on Apple’s Support Communities forum has received more than 3,000 views and 17 replies, and nearly a dozen threads on the issue have been started on reddit.
