I keep a lot of phones & tablets so I literally name them XXX's iPhone Xx and in the case of android devices I just leave them as default. It makes it a lot easier when i need to transfer screenshots etc between devices.
Lol I hear that! I call my primary phone my iPhone 8 but my other one I call my drop phone as I use it when I am going some where or doing something I would not want to do with my 8. In that case I use an old iPhone 6, aka the drop phone.
