Thanks for the info. I usually keep my watches 2 years. I could tell that the battery on my 6 classic was starting to goMost of us on here get the next flagship model almost every year, so it's pointless really if you're not keeping the device long.
I personally don't like limiting to 90% because I would always feel like the battery is running low too quick after getting up in the mornings.
I do have the battery health setting enabled where it stops charging at 100 then allows the battery to drop to 96 before charging again.
