Apple recently updated its iOS version statistics for developers. The company says that 81% of all iPhone and iPod touch devices now run iOS 13, while 73% of iPads now run iPadOS.
According to Apple’s website, 92% of iPhones introduced in the last four years are running iOS 13, while 7% are still running iOS 12 and only 2% are running previous versions of iOS. When considering all the iPhone and iPod touch models ever shipped, 81% of devices are running iOS 13, while 13% are running iOS 12 and 6% are running an earlier version of iOS.
Apple’s usage data is based off visits to the App Store as of June 17. The “four years” time metric is presumably a way to avoid having devices that can’t update to the latest version of iOS reducing the adoption percentages.
These numbers were shared just ahead of WWDC 2020, where the company introduced iOS 14 and iPadOS 14. The developer beta is now available and we expect to see a public beta sometime in July.
