Watch series 7 - Heart rate, Blood Oxygen and ECG Sensors not working

Hi, I have been using Apple Watch Series 7 for a year.

Battery Health: 90%

Out of nowhere, suddenly all apps - Heart rate, Blood Oxygen and ECG apps are not working and sensor light was not turning on.

Tried hard reset multiple times, unpaired, erased content and reinstalled multiple times. Resetted iPhone settings as well.

Running latest Watch OS 10.0.1 software as well, nothing was working.

The Watch battery is also not holding up and getting dried in 4 hours with all sensors turned off.

When I contacted Apple support, they ran MRI diagnosis and conveyed sensor failed and device replacement as the only solution.

Since the device age was 13 months, now hardware warranty is out of question.

Any guidance on this issue would be of great help.

Thanks in advance.

Reach out to Apple Support and see if they can help you sort this out. You may need to ask to speak to a supervisor and be polite and patient with them but firm. You may need to try this several times.
