Ever since i installed the latest official update my watch barely lasts 3 Hours on a full charge. Samsung are you trying to force us to buy an ugly Galaxy Watch 8 that we don't want???
Do a cache wipe using watch recovery mode. To access Recovery Mode on a Galaxy Watch 6, hold both side buttons to power off, then release and quickly press the Home (top) button repeatedly until the Reboot Menu appears, select "Recovery" by long-pressing Home, then use the Back (bottom) button to navigate and the Home button to select options like "Wipe data/factory reset" to fix issues, as described in this Samsung support article.
