Not really. They own like 50% of the market. They position like 1960 GM. The $1,500 iPhone is the aspirational thing that everyone talks about. If you have money, you buy the iPhone Xs (ie the Cadillac), if you want to look "better", buy the Xr (Buick), if you don't care, you buy the iPhone 7 (the Chevy). There is almost nothing that the $1,500 phone does that the $1 phone does not. The cheapo androids are more like…
Where is your evidence supporting the claim that Apple owns 50% of the market? That is way above the figures I have seen. Seems to me you are just pulling metrics out of thin air in this post.
I focus on the US (and UK and Japan), it's a two horse race. You can segment it all sorts of ways. iOS is somewhere between 40-60% in a given segment, and usually around 43-48% overall. Overall share has been declining as the market growth slows and prepaid plans make total device cost more relevant.
Nothing I said means anything ex US, as the solutions, costs and requirements vary.
