Apple Is Slow-Rolling iOS 27 Adoption, So Far

David Smith, last week:

Been really interesting to watch the iOS 27 adoption curve over the first two weeks. Clearly on a different path than previous years. Still steadily growing, at a similar rate to the ‘steady growth’ phase of most years, but without the big surge at the start. Given that this rate is largely controlled by Apple’s automatic update logic, I suspect it’s a deliberate choice. Likely because it lets them manage the Siri AI waiting list and avoid a big queue on day one.

Smith’s numbers are from analytics from users of Widgetsmith and Pedometer++. If you look at his chart for Widgetsmith, there’s really no explanation other than Apple pushing automatic updates to users more slowly than in any previous year, and I think it makes sense that this is to gate admissions to Siri AI. You can also see from his chart that Apple has been slowing down updates to initial .0 versions in recent years — the adoption rates were much faster for iOS 15 and 16 back in 2021 and 2022. Note too that every year Apple makes it more and more likely that users will opt into automatic software updates. The overwhelming majority of iOS users get OS updates when their devices update themselves.

And remember the whole thing with slower-than-previous-years adoption of iOS 26 last year — that was all attributable to the auto-update pace set by Apple.

(It’s purely personal anecdata, but I feel like Siri AI has gotten worse since iOS 27.0 was officially released. It feels a bit slower and I seem to get worse answers, sometimes. I asked it for a word today, using it as an interactive thesaurus, and it simply told me it couldn’t. It never did that over the summer. I started using iOS 27 full-time on my iPhone the day after the WWDC keynote and I got into the Siri AI beta the next week. While it might be some sort of placebo effect, I feel like Siri AI was better — slightly faster and more useful — in July and August than it is now. I could be wrong, or maybe just unlucky of late. But I’m also quite certain that scaling up the Private Cloud Compute side of Siri AI is a massive challenge for a platform with over a billion Siri AI-eligible users.)
