Apple says 77% of all iPhones are running iOS 17

Apple has updated its iOS adoption rate data, revealing that iOS 17 is now installed on 77% of all compatible devices – that’s a little lower than the 81% installation iOS 16 achieved.

Most iPhones run current operating systems

In terms of all iPhones introduced across the last four years, iOS 17 is installed on 86% of devices, in contrast to 81% of devices this time last year that ran iOS 16. (Note that iOS 16 was a really interesting release that saw a higher install rate than its predecessor).

It is interesting that this is the case. It may possibly reflect that Apple’s software development teams have been focused on Apple Intelligence and visionOS across the last couple of years, which blunted the ‘whizz-bang’ feature list in iOS.

(Which isn’t to say iOS 17 lacks great features, it doesn’t, but the release felt a little more like a maintenance release).

I don’t imagine Apple is hugely concerned at the slightly slowed upgrade pattern. It is still true that 91% of all iPhones in use and 85% of all iPads are running a version of the iOS that is no more than two iterations old.
