Apple gave more statistics on the popularity of iOS 11. They show that "eleven" has a worse party than the "ten" all the time. Despite everything, it's better than Android.
iOS 11 is currently installed on 65% of iOS devices . This is the result of the latest statistics published by Apple on the pages of its developer support page. At the beginning of December 2017, iOS 11 was still installed on 59% of devices, when the result jumped by 13 percentage points compared to November 2017. Almost one-third of Apple smartphones and tablets are still running on iOS 10 (28%). The statistics show that 7% of devices use the earlier release of the system. Adoption of iOS 11 since its release is significantly worse than iOS 10. For comparison, the "ten" in January 2017 was already installed on 76% of devices controlled by iOS. The number of errors, unfinished elements and issued corrections for "eleven" effectively deter significant part of users from upgrades to newer versions. After all, iOS 11 is still better than the next versions of Android. Note that Android Oreo appeared in the fall of 2017, and up to now it is not installed on 1% of devices with this system. Over 28% of Android users use Marshmallows, which appeared in 2015, and over 26% from Nougat (2016). Next week , an update of iOS 11.2.5 will probably appear , which will bring further corrections to the detected holes.Source: Apple , Android
