I meet web developers who cannot accept that most smartphones in the world, and even in the US, are not iPhones. And that keeps them from understanding that the "i" in "iPhone" stands for "inequality":
Time series of single-core Geekbench 6 scores for 4 device classes: fastest iPhone, fastest Android, mid-range Android, and low-end device (~$100).
The Performance Inequality Gap is growing, year on year, and the lower tiers are not even on the same trend line, let alone catching up.
Average selling prices in nominal USD for iOS and Android devices vs. worldwide smartphone Average Selling Price.
iPhones aren't real life.
Worldwide smartphone shipments by year in millions; sources: IDC, Statista, and Counterpoint Research.
At no point in the past decade have iPhones broken the 20% annual sales barrier. iOS is overrepresented in traffic statistics owing to wealth-correlated effects; e.g., faster networks and devices inducing heavier internet use. This does not imply that users on slower devices do not have money to spend, only that they are poorly served by today's web developers.
