Do you really believe the average consumer just visits Apple‘s website to see the comparison page for differences of a smart phone? They upgrade probably through incentive through their carrier (Rather due to aging battery/lack of iOS support), to pick the color/storage/price, that’s really about it. I mean, that’s like asking if they know what 3D Touch is, which we all know they don’t know what 3D Touch is or how it even works. And you’re giving credit thinking that they spend time on Apple‘s website to figure these things out? Likely not. I think you’re giving way too much credit here for all the features that consumers generally don’t understand (And Probably don’t care to), aside from the camera, which Apple heavily promotes.
As already iterated, Consumers don’t care about the naming scheme of an iPhone, however it’s confusing when Apple uses monikers like XR/XS (Which is why it’s more sensible to use just a simple number versus these in between variable numerics).
All that matter is this, Consumers see three things, 1.) Price, 2.) Color and 3.)Storage option. Nothing else is really that major of a selling point to them in terms of what their previous smart phone does that all the newest phones typically offer aside from Face ID/Tri-Lens.
Ok? Do you think consumers care? Why would they need to know what every model offers in terms of tangible differences of every little feature, I’d wager that consumers want the price point of the v.s. the mentality of “I want the most expensive iPhone Apple offers”, <—That’s not logical] which is probably indicative of why the XR sold so well in 2018, and why the iPhone 11 is vastly popular today.
The endpoint, the naming scheme is confusing, and I have no doubt you could ask an average consumer what XR stands for or what XS stands for, and they probably couldn’t tell you the differences between those phones, let alone what that actually means, which I doubt they spent time on Apple‘s website trying to figure out those differences. They probably select the phone based on what their carrier is promoting through incentives/promotions, which is probably the entry-level iPhone under the ‘Pro’.
