Watch OS7 Issues

I updated my series 5 to OS7 and have the following issues:


Heart rate sensors are no longer illuminated/working which means activity data and heart rate is not functioning.


Battery drain - at 22% when I charged last night, normally around 45~50% before update.


Is anyone else having these issues?


I also updated my iPhone X to IOS14 - no issues found apart from the lost functions of the watch.

The heart rate sensors are not turned on constantly and only measure briefly throughout the day to find your heart rate when you aren't doing a workout. (Under a workout, it will "illuminate" for 100% of the time.) You can check that "illumination" by going into ECG or the heart rate app. (I have no idea on frequency.)


If you aren't receiving any data on your phone throughout the day, follow these troubleshooting steps below.


Close certain apps and then restart (normally) both your iPhone and your Apple Watch:


Turn both devices off together, then restart your iPhone first:


If you have previously used any third-party fitness tracking, sleep tracking or heart rate monitoring apps:

  • Check whether there is an active or paused session within any of them.
  • If there is, then end that session from within that app on your Apple Watch.
  • If in doubt, it may help to remove any such third-party apps from your Apple Watch, at least temporarily.


People have said that Apple may have (not much evidence) reduced readings when moving constantly due to inaccurate readings, I have no idea why that is the case.
