Apple has revealed the latest iOS 17 and iPadOS 17 installs

It doesn’t take a geek to be naturally curious about how fast modern iOS and Android programs are spreading. It used to be interesting to look at Android’s distribution figures each month. Of course, because of the fragmentation that remains a hallmark of the platform, the last major OS build was never installed on most Android phones, though that’s recently changed. Because Apple makes both the software and the phone, iOS distribution figures are different. You’d be surprised if a version of the latest major iOS release doesn’t end up on the vast majority of iPhones.
According to statistics cited on Apple’s developer site, 86% of all iPhones released in the last four years run iOS 17. Far fewer — 11% — have a version of iOS 16, and 3% of iPhones are running an older iOS build.
All iPhones are running an older iOS build.
The numbers above show the rate of iOS adoption on iPhone models introduced over the past four years. If we look at all currently active iPhone models, 77% of them are using the iOS 17 version. 14% of all iPhones in use today are running an iOS 16 build, and 9% of those iPhones have iOS 15 or older installed. It would be interesting to know the oldest version of iOS that is currently still in use on an iPhone.

Now suppose we turn our attention to the iPad. 77% of all iPad models released in the last four years run the iPadOS 17 operating system. 15% of those tablets have a version of iPadOS 16, and 8% have an older build of iPadOS installed.
About 15% of those tablets have iPadOS 16, and 8% have an older build of iPadOS.
Looking at all active iPad models, 68% are running a version of iPadOS 17, while the iPadOS 16 operating system build is installed on 17% of active iPad models. 15% are running an older version of iPadOS.
All data is based on iPhone and iPad models purchased before June 9, 2024. The latest Android distribution data was released in October and showed that just weeks before Android 14 was released, Android 13 (22.4%) had the most Android 13-based phones (22.4%), followed by Android 11 (21.6%), Android 10 (16.1%) and Android 12 (15.8%).
