For those with the iPhone X or newer devices, how long do you plan on holding onto your current device? What about future iPhone XR owners? I plan on using my XS Max for at least 2-3 years. I am not really interested in 5G because 4G LTE works for me fine and I would rather wait a few generations to see 5G coverage refined. I don't need a faster processor or more RAM or a better camera. I wanted to find out how a contemporary form factor, especially one that will be used for a bit, impacts your preferences.
