What is the average battery life for the Apple Watch Ultra 2?

I am running watchOS 11.2 and the latest iOS (18.2.1). My watch does not have cellular. Here are some recent battery percentages:

1. 1/14 to 1/16 - dropped ~22% in ~48 hours - less than 0.5% per hour (seems good)
2. 1/14 to 1/17 - dropped ~58% in ~77 hours - around 0.75% per hour (not as good, especially given the lower percentage per hour in #1)
3. 1/18 to 1/20 - dropped ~71% in ~52 hours - about 1.4% per hour (getting worse)
4. 1/20 to 1/22 - dropped ~45% in ~45 hours - about 1% per hour (meh)

I am not using my watch for much - I used the Strong app for about 30 mins on each of 1/17, 1/19 and 1/21. My watch face is Modern Ultra but I've only got the following Complications running: Today's Date, Last Viewed Waypoint, Sunrise/Sunset and Temperature. (Although I have been relatively local, I turned off Last Viewed Waypoint as I post this.)

I have read the suggestions online and unpaired and reconnected my watch *before* noting the above stats.

Is this normal?
