iPhone users little unimpressed with iOS 15, shows Apple's iOS adoption data

Apple has released fresh iOS 15 installation numbers in which only 72 per cent of iPhone devices from the last four years have been upgraded to iOS 15, and this is much slower than iOS 14's adoption rate.

Apple has said 72 per cent of all the iPhones released in the last four years now use iOS 15, while if you count iPhones that were introduced more than four years ago, the iOS 15 installation number stands at 63 per cent. The new installation data for iOS 15 landed on the Apple website for the first time since iOS 15 was released in September last year. The 72 per cent coverage of iPhones up to four years old shows the adoption has been steady and can grow over time, but slower than the adoption rate of prior iOS versions - maybe because iPhone users are not that impressed by iOS 15.

The fresh installation data shows that while 72 per cent of iPhone devices from the last four years are on iOS 15, 26 per cent of iPhone devices still continue to run on iOS 14. And there are a handful of iPhones, 2 per cent to be precise, that are on iOS versions older than iOS 14. If you talk about all iPhone devices, only 63 per cent are on iOS 15, 30 per cent on iOS 14, and 7 per cent on earlier iOS versions.
