I agree. I had a Huawei P30 Pro before I spent £1200 on an S21 Ultra and it was a challenge to drain the smaller battery on that in a day with everything running at full throttle. I'm sick to death of hearing about tips and tricks to save battery on this S21 Ultra, it just shouldn't be a thing we should be concerned about, it should just work. Turn this off, put that into sleep, restrict this, delete that app, blah blah blah. I didn't buy a feature rich phone to turn them off to save battery.
