I noticed this on z fold 4 as well. That's too bad that after spending a bomb on buying fold4 a month ago, the battery drain issues r happening. This is not expected from samsung.
I also noticed that somehow the refresh rate changed to 120hz. I had set it to 60 earlier, may be that is the issue with the October update. I reverted it to 60 now and will watch how battery performs now.
