Ok, a full wipe later and a fresh download of Beta 6 seems to have done the trick apart from one little stutter!
When I open settings my name and Apple ID picture, along with the first three lines of the menu below - 'Airplane mode' 'WiFi', and 'Bluetooth' take a split second behind the rest of the menu to load.
My wife has the regular 16 and her does exactly the same, so I'm guessing it just needs sorting out when B7 or the RC rolls out.
