iOS 11 installed on 76 percent of all compatible iOS devices
Apple has managed to get three-quarters of all iOS devices equipped with the latest operating system, which is a tremendous success for the team Attention Rate Notable: This is now 11 percentage points higher than on January 18, when iOS 11 was installed on 65 percent of the devices, and 24 percentage points higher than on November 6, 2017, when iOS 11 was installed on 52 percent of compatible devices. The 11 percentage point increase is attributable to the launch of iOS 11.2 in December and iOS 11.3 in March, both of which contained important new features.
iOS 10 continues to be used on 19 percent of devices, while 5 percent of devices continue to use it Versions of iOS like iOS 9 have. Many of these devices are probably older and can not be upgraded to the latest version of iOS.
iOS 11 adoption has grown steadily, but significantly slower than iOS 10. In February 2017, for example, iOS 10 was installed on nearly 80 percent of active devices. That's not surprising, as users learn: iOS 11 has some really bad bugs and issues like the HomeKit bug, the Specter and Meltdown vulnerabilities, and most of all the iPhone brake that slowed down the performance of older iPhones , Somehow you can already understand that the users have been a little more cautious, although the restraint was not significant.
Currently, Apple is already testing iOS 11.4 and of course already iOS 12, which will probably be introduced at WWDC 2018 and in the September 2018 will be on the market.
