Apple watch connection

My Apple Watch doesn’t keep connecting to my iPhone and frequently disconnect and reconnects (it happens about 2-3 times per minute).

This has caused my watch to run out of battery quickly and notifications to appear delayed on my phone.

This issue occurred after updating my phone to iOS 17 and my watch to iOS 10, as I did not have these problems before the update.

I have done below steps in order to solve these problems but it didn’t work:

1. Update my devices to the last version. 
2. Unpair the watch and pair again. 
3. Reboot the devices. 
4. Reset the watch to factory settings.
5. Reset the iphone to factory settings.

How can I fix this problem?
