iOS 8 now installed on 68 per cent of Apple devices

It has been revealed by Apple on its App Store Distribution page that iOS 8 is now installed on 68 per cent of devices, including iPhones, iPads and iPod Touches.

iOS 7 now runs on 29 per cent of devices, which is 3 per cent down from previous figures, with 4 per cent of Apple device owners are still using older iterations of the iOS.

The number of people using iOS 8 has risen by 4 per cent since numbers were last released on 22 December.

It was previously reported that Apple was disappointed with adoption rates of the new operating system, with just 47 per cent of iDevice users having downloaded iOS 8 by the beginning of October. By the end of the month, this had jumped to 52 per cent.

Apple's latest operating system was released on 17 September, when there were various complaints about bugs and problems. One major issue experienced by users was about the size of the update, for which Apple is now being sued.

The argument is that on devices such as the 16GB iPhone 6, the size of the iOS 8 update diminishes the amount of storage space the phone is advertised for by around 3GB (19 per cent).

Shortly after the release, Apple withdrew the ability to downgrade to iOS 7 after installing iOS 8, releasing subsequent updates in order to address ongoing teething problems.
