So says Kantar Worldpanel ComTech, whose latest figures show that iOS' slice of the pie fell 8.5 per cent in the three months ending October, giving it a 33.9 per cent share of the United Kingdom market.
Unfortunately, this lack of consumer interest towards other devices resulted in Apple dropping a few percentage points in the USA for its market share but now that the iPhone X is officially here, this is not necessarily a bad thing.
Market share declined by 6.9% in Japan, 1.6% in Germany, 0.6% in France and 0.5% in Italy.
In an analysis of smartphone operating system sales for the quarter ended October, Kantar also said iOS market share slipped in Japan and key European markets, while Android clocked gains in most markets. The company released a new update for Gmail for iOS today, bringing support for third-party email services as well as the iPhone X's display (via The Verge).
It's a bit odd that it took Google until now to get to Gmail for the iPhone X, as it has already seen its way to updating Waze, YouTube, Google Home, Maps, and the aforementioned Drive apps.
"Urban China, a market once overrun with new challengers, is maturing", we're told, "with the top five players all posting strong growth and the long tail of challenger brands falling away rapidly".
This, the analyst outfit claims, is largely due to the fact that the iPhone X wasn't made available until the end of October, along with the fact that the iPhone 8 - which was available in September - offered few upgrades compared to the iPhone 7.
