Excesive battery drain on iPhone 16 Pro

For context, I am on iOS 18 and have a dynamic wallpaper as well as widgets on my lock screen but is it normal for my iPhone 16 Pro to drain from 98% at 11:30 to 81% at 21:30 whilst just idling all day?

Coming from a 5 year old iPhone 11, I know for sure that one day I kept it on my desk for around 12h with very very minimal use and it was at 100% the whole time. What is happening?

No. 1 usage in the battery usage break down over the last 24h is "Home and Lock Screen" with 47% equating to 33m (so I only used my phone for 1h in the last 24h...), and 10 days it's in second place with 18% - 4h 27 min.

Could this be from the dynamic wallpaper and lock screen widgets? Auto-lock is on 30 seconds and I do NOT use always on display. I've left a screenshot for a better understanding.
