If you look at the top right, it says 5G. This may be the cause of battery drain because 5G uses loads of battery. This shouldn't be the cause of the issue if you turn your mobile data off when you go to sleep.

That is a very high Google Play Services reading.

Try wiping the cache partition and using the Galaxy App Booster. See...

And even with 5g on a phone shouldnt drain 30% within 8 hours standby time with such little usage. I use a Samsung galaxy A51 5g and I have used 5g all day with 70% battery left after 13 hours standby time and 2 hours 13 minutes SOT. And this is a midrange phone, something else is going on, might be worth trying to get it to a Samsung Experience Store
