In Japan, the iPhone commands around 65 pc to 70 pc of all smartphone web traffic, even higher than its share in the US.
Global desktop market share for macOS is 15.31% according to https://gs.statcounter.com/os-market-share/desktop/worldwide
It is well known for decades that a Mac user spends many times more on software for that Mac than a PC user spends for software, so it is reasonable to conclude that an iPhone user visits more web pages.
