Apple’s iOS 9 went live on Wednesday, and the adoption rate in the first 24 hours matches that of iOS 8, according to analytics data from several sources. Mixpanel’s live tracking data suggest that approximately 12.6 percent of the devices are now running iOS 9.
iOS 9's early adoption rates have just about matched iOS 8’s, and falls short of iOS 7. However, there are some variations in the figures from different analytics sites. GoSquared and Paddle suggest that iOS 9 has been installed on 12 and 11.84 percent of devices, respectively. It is at par with Mixpanel’s count. While Tapjoy has reported rates between 4 to 7 percent, Fiksu put the figure at 6 percent. The variation can be explained by the difference in the selection of users that each company has tracked, through app installs. However, all of them agree that the growth rate of iOS 9 installs is in line with that of iOS 8.
The latest update requires 1.3GB of space, compared to 4.58GB for iOS 8. Mobile intelligence firm Crittercism believes that the iOS 9 adoption rate will overtake that of its predecessor in a month. The lower-than-expected numbers can be attributed to the apprehensions that some users might be having over the stability of the new update. With fewer crashes and lesser installation space required, more users will be tempted to upgrade their devices. The servers have been struggling to cope with the initial rush of requests, which has contributed to iOS 9's adoption being slower than iOS 7. CEO Tim Cook’s suggestion that users might soon be able to remove some pre-installed apps will also free up storage space.
While iOS 9 has achieved a 12 percent adoption in 24 hours, it took Android’s Lollipop 5 months to attain the same. One of the key factors contributing to the mismatch is that, unlike iOS devices, there are hundreds of manufacturers making Android devices, with an endless combination of hardware. It often takes months for each manufacturer to optimize the latest Android update for each device.
