Apple Watch Series 5 battery drains rapidly after using the Activity app

Why is my series 5 Apple Watch battery going from 100% to 10% in a matter of a few hours? This happens after using the activity app usually when I swimming in the pool or walking my dog.

Has the battery ever been replaced by Apple?

If the Battery Health is below 80%, it is time to get it replaced. I had to charge my old Series 5 twice a day at that point.

Using the Workout app will consume more battery life than just wearing the watch throughout the day.
