Please note that this article is out of date. To get the newest data about iOS versions, please visit the iOS versions market share category.
As of November 13, 2022, these are the market shares of major iOS versions in the TelemetryDeck data set:
Unsurprisingly, the newest operating systems, iOS 15 and 16, are the most used. What is surprising is just how quickly the newest iPhone operating system has surpassed its predecessor.
Adoption of iOS 16, which was released to the public on September 12, 2022, was fairly quick. After just one day, more than a quarter of iOS devices in the TelemetryDeck data set were running iOS 16.
(Also note the long tail at the left end: Apple seems to very actively run a large number of apps on the App Store on internal beta builds of upcoming OSes to ensure compatibility)
On October 20, 2022, just 39 days after the public release, more devices were running iOS 16 than were running iOS 15, at 46.5% running iOS 16 and 44.5% of devices running iOS 15.
As of November 3, 2022, more devices are running iOS 16 than any other iOS version.

This chart shows how quick to update iOS users are. Every time Apple releases a new version, be it a point release or a major new version, an overwhelming majority of users are very quick to update.
Case in point: on 2 June 2022, before iOS 16 was released, over 80% of iPhone users in the TelemetryDeck data set were using the current active version, iOS 15, with around 6.8% on iOS 14 and the rest on even older versions or betas.
This is excellent news for developers and users alike: users who run the latest versions of the operating systems not only get all the new features (and emoji ) but also tend to be more safe from malware, spyware, and security leaks.
And of course this is wonderful news for developers: it means that many developers can require current versions of iOS earlier, allowing them to use new features and provide new capabilities in their apps.
