Same here s21 exynos, before AUB3 update had 48 hours with low use after update 30 hours. Today after full charge it's draining 5% per hour in standby screen off.

As a rule of thumb, always make sure location is only accessible by apps when their open bar a few.
Check your app permissions for location.
Also if you don't have good signal, it will drain battery as phone has to work harder to get signal.
google is normally the biggest culprit for background stuff, or some rogue app.

Same problem, after the latest Update, almost every night, s21 is losing like 40% in standby! AOD is off, Location is off, nfc is off, 5g is off! Before going to sleep, switched off all recent apps, but still drained!WTF!!!!?

This is my usage after AUB6 update. On the first picture before red lines it's usage with 3g and before update. Between 2 red lines it's usage after update with 4g . On the second picture i lost 7% with 9 minutes of SOT with 4g on and connected to wifi. I'll try to factory reset phone, but if that doesn't improve battery life ota update didn't fix bug for me.
