Is it normal for Apple Watch SE 2 battery to drain quickly?

I've had the Apple Watch SE 2 for a week and I wanted to understand if it's normal for the battery to last so little.

I charge it at 10 pm and at 10 pm the next day it's about 30%. I don't do workouts, I use it for sleep monitoring and WhatsApp and Calls notifications. Is it normal you last so little?
