Estimated user data shows almost 21% of active iPhone users have upgraded to the new iOS 15, but that's behind the number who moved to iOS 14 over the same period last year.

Initial figures from research firm Mixpanel, showed that about half as many users updated to iOS 15 during its first two days, compared to iOS 14 in 2020. By September 22, 2021, it was believed that 8.5% of users had updated to iOS 15, compared to 14.5% going to iOS 14 in its first two days.

Now Mixpanel has released data covering iOS 15's first two weeks. The company's data is based on analysing the devices of visitors to its websites, and estimates that 20.74% of traffic is coming from iOS 15.

In comparison, iOS 14 had 40.51% adoption by its second week.

At present, Mixpanel reports that 73.48% of users are on iOS 14, and 5.78% are on older versions.

Apple is already preparing iOS 15.1, and the first developer betas of it have been released. It's expected that the update will fix some of the many bugs found in the initial iOS 15 release.
