Early iOS 9 Adoption Rate in Line With iOS 8 Adoption
Mixpanel's live iOS 9 tracking site suggests iOS 9 is now installed on approximately 12.60 percent of devices, which is in line with iOS 8 adoption rates in 2014.
"iOS 9 has received 12% adoption in the last 24 hours and is being adopted similar to iOS 8 last year. This kind of adoption took Android's latest operating system, Lollipop, in comparison 5 months to achieve. One huge advantage Apple got right this year over last year was that the update is much smaller than last year (3.5x smaller) < Apple has empathy for its users who have nearly maxed out the space on their phones. However, one issue for it being substantially slow compared to iOS 7 is that servers are having trouble keeping up right now as people update."Because each analytics site tracks a different selection of iOS users based on app installs, iOS 9 installation numbers vary quite a bit across platforms. All of the sites tracking iOS 9 adoption agree that it is on pace with adoption numbers seen after iOS 8 was released last year, however. Tapjoy is seeing adoption rates spanning from 4 percent to 7 percent, based on device, while Fiksu is seeing 6 percent of its users running iOS 9.
According to GoSquared, iOS 9 users now represent 12 percent of total iOS traffic, a number that's on par with both Mixpanel's count and an 11.84 percent measurement from analytics company Paddle.
Two years ago, iOS 7 saw much quicker adoption rates than we're seeing with iOS 9, but that is not surprising as iOS 7 marked the last major design update to the operating system. iOS 8 and iOS 9 brought many new features, but few visual changes.
What is surprising is that iOS 9 adoption is not outpacing iOS 8 adoption because iOS 9 has a much smaller installation size. While iOS 8 required 4.58 GB to install, iOS 9 only requires 1.3 GB, making it much more accessible to users who have little space open on their devices.
