14 DAY TRIAL // After only 48 hours since the release of Apple iOS 9, the new OS has already been installed on more than 20% of the total number of iOS devices capable of running it.
Right after the iOS 9 launch, users experienced all sorts of problems upgrading their iPhones, iPads and iPod touches to the latest version of iOS because of the sheer number of requests Apple's update servers were getting.
As detailed by a Mixpanel graph, after Apple managed to fix all update problems, users have been able to update their devices at their pace, and as we speak, iOS 9 is at 20% adoption rate, 20.87% to be more exact, with iOS 8 at 71.29% and going down as the new release gets installed on more and more iOS devices.
All other iOS versions besides iOS 9 and iOS 8 are installed on 7.84% of all iOS devices, with the mention that among them are also devices running Apple's latest iOS 9.1 Beta.
This happens right after iOS 9 reached 12% adoption rate in only 24 hours, thus picking up speed towards completely overthrowing the older iOS 8 release.
iOS 9 adoption rate speed suffers when compared to the iOS 7's 20% in 24 hours
Even if 20% in 48 hours seems fast, this number was reached by the iOS 7 release in only 24 hours because it came with a refreshed interface that made most iOS users want to have it as soon as possible.
iOS 9, on the other hand, has been developed as a release designed to fine-tune the previous iOS 8 version, with little news besides the addition of a News application, a Low Power mode, better security, and improved Siri personal assistant.
Although it makes most iOS devices it supports a lot snappier, iOS 9's user appeal is not on the same level as iOS 7's was, therefore, a slower adoption rate is to be expected.
