Apple has released iOS 15 release data for the first time since the major update was released in September.
iOS 15 is installed on 72% of all iPhones introduced in the last four years. 26% of devices continue to use iOS 14, while 2% are running an older version of iOS. If you also count iPhones released more than four years ago, 63% are running iOS 15, 30% are running iOS 14, and 7% are running an older version of the OS.
The delivery of the latest major update is weaker on the iPad. 57% of all iPads introduced in the last four years use iPadOS 15, while 39% continue to use iPadOS 14. 4% run an older version of the operating system. Counting all iPads, including those released more than four years ago, 49% of devices are running iPadOS 15, 37% are running iPadOS 14, and 14% are running an older version of iPadOS.
Apple divides the data into two separate groups because there are still devices in circulation that cannot run iOS 15 or iPadOS 15, and would therefore skew the figures on the release of the latest updates.
Either way, iOS 15 lags behind the numbers recorded by previous versions. iOS 14, for example, was installed on 81% of iPhones released over the past four years as of December 2020, marking a much higher update rate a month earlier than iOS 15. iOS 13, another update update which saw a slower installation, it was installed on 77% of devices at the end of January 2020.
Recall that from this year, Apple allows users to stay with an older version of the operating system, while still being able to receive security updates. This possibility has probably convinced several users not to abandon iOS 14, at least for now.
