I purchased an iPhone XS Max and set it up as brand new (it obviously came pre-installed with iOS 12). I had some issues with it bothering my eyes so I returned it, but before I did that, I made a backup so I wouldn’t have to set my next phone up as new. I got an 8 Plus (which had iOS 11 on it) and upgraded it to iOS 12. After I updated it, I then reset the 8 Plus to clear any stuff off of it since it was running iOS 12. I then took the backup of my old XS Max and put it on the 8 Plus. Now, I’m considering getting the XR which comes pre-installed with iOS 12...if I backup my current 8 Plus, will the old iOS 11 stuff that was reset (then updated to iOS 12) transfer over to the new XR? Or will the XR be good to go as a clean install?
