The OP is not making this up. Many 7 pluses had this problem. Especially at launch.
Yes, at launch most of the 7+ phones were doing it, there are even
articles about it. Apparently it was persistent enough that some stores refused to replace the phones, as the replacements had the same issue.
I checked months ago, and mine did it, but I never thought it was worth worrying about.
