Design-wise TechRadar's Gareth Beavis says that next to the iPhone XS the new iPhone XR is "not quite as attractive", pointing out its thicker bezels and drawing your attention to the fact that its edges aren't made out of the same premium-feeling materials.
There's a good working theory that the iPhone X was an experimental phone that cost a lot to produce, and that Apple chose not to make it available at a discounted price to avoid cannibalising sales of the XS.
The year-old phone was Apple's flagship product last year, and it was warmly received by critics.
That being said, on its own he notes it "could be mistaken for the iPhone X of last year". The last time it discontinued an iPhone model a year after announcing it was the iPhone 5, released in 2012 and canned in 2013.

The iPhone XR starts at $749 with 64GB of storage, the same price as a smaller screened iPhone 8 256GB model and $50 more than an iPhone plus with 64GB of storage. Why pay $US999 for the unbelievable screen on the iPhone XS or iPhone XS Max when you could effectively buy the same phone for $US100 less?
The affordable model iPhone Xr instead comes with 3 GB of RAM just like the original iPhone X. Coming to benchmark scores, Geekbench highlighted a very high result in single-core performance for the iPhone Xs Max: 4813 points, that is much better than the previous generation, while there is just a slight difference in multi-core performance with 10266 points.
