This may be because of the Optimised Battery Charging function, that will make your Apple Watch stop charging at 80%.

To turn this function offdo the following: Go to Settings, Battery, Battery Health, and then turn off Optimised Battery Charging.

Last update changed the charging profile. My battery optimisation is OFF and watch will never charge past 82%. Even when I catch it at 82% and touch the charging circle, it says it will keep charging but never does.


Big problem for me because I often have long workouts that require a full battery to capture the whole thing. Super frustrating.


There must be a background process that is now preventing full charge regardless of user input.
