I've got the Samsung watch 5 Pro. Whenever I do exercise it shows the correct calories burned on the health app rings. However as the day progresses the calories end up dropping off. For example this morning I burned 450 calories doing exercise which were shown on my watch heart however and my overall calories were about 500. Now 3 hours later the overall calorie count is down to 117. It totally defeats the purpose of a smart watch. Any ideas how to fix it?
