Question

Apple watch ultra makes continous sound for 5 seconds throught the day

I wonder someone can help me.

Since 3 months ago my Apple watch Ultra version 1 starts making a loud noise like it is a RAM issue or similar.

The sound appears several times a day and when I am using my Macbook Pro.

I did the diagnostics on my Macbook Pro and the report signaled issues with the charging port and the trackpad.

I can tell that it comes from the watch because I went to another division of my house (without the Macbook).

Anyone with noise issues on Apple Ultra ?

Thank you

Apple Watch Ultra, watchOS 11

Did you set up your watch to unlock your Mac or your iPhone?

Did you enable any alertsfor leaving your devices behind? This will also trigger a sound on your watch.

To me this does not sound like a normal watchOS sound.

To rule out a software issue, unpairing the watch and setting the watch up as a new device would be the next step, in case the issue is part of thee backup data.

Did you try to charge your watch, using the USB port of your Mac? The Apple Watch Ultra needs at least a 20 W Apple power adapter to charge properly.

No I didn't try to charge using the USB port. I always use a 30w Apple power adapter.

Does the issue stop, if you disable the unlocking feature?

Did this start after updating the firmware on the Watch or Mac?
