46 Percent of Apple’s Mobile Devices Already Running iOS 8

iOS 8 for Apple’s mobile devices launched less than a week ago, but the company is already reporting that nearly half of the active devices in customers’ hands are already running the latest version of the operating system.
As of September 21, 46 percent of devices that connect to the App Store are running iOS 8. iOS 7, which was introduced around this time last year, still accounts for 49 percent of installs. iOS versions prior to iOS 7 account for the remaining 5 percent of installs.

iOS 8 is tracking behind the swift adoption of iOS 7 a year earlier — analytics firm Chitika estimated that iOS 7 was installed on 52 percent of devices one week after its public release. However, it should be noted that those numbers came from a third-party and weren’t validated by Apple like the current iOS 8 tallies.
iOS 8 is supported on iPhones dating back to the three-year-old iPhone 4S and the three-year-old iPad 2. iOS 8 is also supported on the fifth generation iPod touch.
iOS 8 of course come preinstalled on the newly released iPhone 6 and iPhone Plus smartphones. Apple announced yesterday that it sold over 10 million of the new devices during the first weekend of availability.
