Figures Reveal 52% Have Upgraded To iOS 8
Last month Apple reported that 46% of iOS users have upgraded to iOS 8 and now, new figures have been revealed that 52% have upgraded.
Last month Apple released iOS 8 to the public and now it has revealed that over 52% have upgraded to the new operating system.
The percentages on the App Store Distribution page specifically reveal the number of devices that visit the App Store on a given date.
So they don’t provide a full picture of iOS 8 adoption but at least offer the measurement officially recorded by Apple.
Data from fellow mobile analytics firm Fiksu showed a slightly lower adoption rate for iOS 8. As of Monday, Fiksu’s figures cited iOS 8 with a 48.5 percent share and iOS 7 with 43 percent.
The numbers reported by Apple and the mobile analytic’s firms don’t distinguish between people who upgrade their existing devices to iOS 8 and those who buy new iPhone’s and iPads already equipped with the new version.
