For the first time since Apple rolled out iOS 15 in September last year, the company has updated its iOS 15 installation numbers, revealing that the latest iOS release is now installed on 72% of all iPhones from the last 4 years (via MacRumors).
According to Apple’s data, 26% of iPhones continue to use iOS 14, with 2% of devices running an earlier version of iOS. For iPhones released more than 4 years ago, 63% of them have iOS 15 installed, 30% run iOS 14, and 7% are running an earlier version of iOS.
For the iPad, the installation numbers are, however, relatively lower. Nearly 57% of all iPads introduced in the last 4 years are running iPadOS 15, whereas 39% continue to run iPadOS 14.
Four percent run an earlier version of iPadOS. Counting all iPads, including those released more than four years ago, 49 percent of devices are running iPadOS 15, 37 percent are running iPadOS 14, and 14 percent are running an earlier version of iPadOS.
Overall, the number of iPhones and iPads running iOS 15 lags behind prior operating system installation rates.
