Preview at WWDC likely in June, followed by September launch.
iOS 11 Installed on 10% of Devices 24 Hours After Launch
24 hours after iOS 10 was released last year, it was installed on 14.45 percent of devices. iOS 9, after its release in 2015, was installed on 12.60 percent of devices 24 hours after launch, and iOS 8 saw similar adoption rates in 2014.
iOS 11 was not affected by installation issues or other problems like iOS 10 was, but past issues with new iOS releases may be keeping some users from upgrading right away. The iOS 11 update also disables all 32-bit apps, another factor that could be holding some users back.
Adoption rates often spike up a bit over the weekend when people have more free time to make major software updates to their devices, so iOS 11 could catch up to iOS 10 at that point.
As people begin adopting iOS 11, iOS 10 adoption is trending downward. iOS 10 is now installed on 84.55 percent of devices, while 5.44 percent of users continue to run an older version of iOS.
iOS 11 is a free download that's available for download on the iPhone 5s and later, iPad mini 2 and later, and the 6th generation iPod touch. There are dozens of new features in iOS 11 and several overhauled interface elements, so it's worth an upgrade if you haven't already.
