Myself and someone I know both own Galaxy watch active 2's. There was an update recently and we have both noticed a dramatic loss in battery life. I went to bed last night with my watch at 76% and woke up with it at 12% (7.5 hours later). Looking at the battery statistics in the app doesn't show anything using a crazy amount of battery, with the "Galaxy Watch Active" app using the most at a normal 9%. If this is a wide spread issue hopefully another update will come soon to fix it.
