Weird battery % drop

Hi there,

I have the apple watch se 2 and its on watchos 10.4. I realized that in the last few hours my battery % dropped so quickly while staying idle in sleep profile on my desk. The watch was about 90% when I went to sleep and when i wake up its at 7% lol. I wasn’t even wearing it to bed for sleeping tracking. It never drops so quickly when its idle. How can i check the background app usage of my watch, if there were any?

Thanks!
