iOS 11 is now installed on 59 percent of iOS devices, according to
new statistics Apple shared this week on its App Store support
page for developers. That’s up from 52 percent on November 6,
indicating iOS 11 adoption has grown just 7 percentage points over
the course of the last month.
iOS 11 adoption has been slower than iOS 10 adoption. Based on
Apple’s official App Store numbers, for example, iOS 10 was
installed on 54 percent of devices in October, a month after the
operating system had been released. Comparatively, iOS 11 was only
at 52 percent in November, a month and a half after launch.
I don’t think a difference between 54 and 52 percent is meaningful, especially this year, when many people were waiting for the iPhone X. The iPhone X alone could account for that 2 percent. I think it’s fair to say iOS 11’s adoption rate is about the same as iOS 10’s last year.
