I find it interesting that you mention the word benchmark because reviewers used to rely on benchmarks for new phones and such but then iirc at least OnePlus and Samsung devices have been caught and banned from multiple benchmarks.
Banning them is silly. The benchmark programs reported unthrottled speeds, but when the phone has per app throttling (to save battery) you may not get the speed you measured in each app.
I seem to recall that some manufacturer's have been found to programmatically alter behaviour of hardware & background programs/services when a benchmark is running, creating results that are not achievable otherwise in other programs.
