So you have what I'm achieving above. I do not have battery saver on.
My normal use is 9 hours streaming overnight plus a couple of hours a day SOT and about 30 minutes of calls. I'll comfortably get 24 hours battery life on that.
I have also tried without the 9 hours overnight streaming and got between 2 and 2.5 days battery from 100% to 0.
I am not employed by Samsung nor do I receive any remuneration as a Samsung Members Star.
My device is an S25 Ultra.
