After 7.4.1 update on I watch series 6 the battery lasts only for 3-4 hrs. Unpaired and repaired twice and still battery drain not solved. This kind of poor battery issue on I watch of other series als experienced by many but Apple does not seem to get it right?

I charged my updated Series 6 at 7am this morning and now 7:30 hours later it is at 88%. No problems here. My impression, though, is that after the upgrade to 7.4 I got slightly more battery life. I gather the upgrade to 7.4.1 is a minor security upgrade (though important) and I wouldn't have expected any change to battery life. Odd. You say you have un-paired and re-paired twice: have you tried stopping it and restarting?
