Apple Watch 6 Battery Issue

I have had the Apple Watch 6 for a few months now. During the first week I had it, the watch would turn off, even though the battery level indicator was over 60%. I wouldn't be able to turn the watch on again without charging it over night. I re-paired the watch with my phone it seemed to be fine. Over the last couple of weeks, the watch is dying quickly, even after a full charge overnight. I can visibly watch the battery life go from 100-0 in a matter of minutes. I have tried re-pairing with no success. I have used two different Apple chargers. I have tried several of the tips to prolonging battery life. But this is a fairly new watch. Am I missing something here, or is it possible I have a lemon? Any advice would be appreciated.
