Apple has released a chart highlighting the lack of fragmentation on iOS platforms.
According to the figures, 93 per cent of iOS devices are running the latest version of Apple’s mobile operating system iOS 6.
A further six per cent are using iOS 5, while just one per cent are using an earlier version of iOS.
The figures are based on devices accessing the App Store over a period of two weeks ending on June 3rd.
The chart was posted to its Optimising Apps for iOS 6 developer page.
Fragmentation is likely to increase as the number of iOS devices incapable of running the latest version is likely to increase in the future.
iOS 7 arrives later this year. It will support the iPhone 4, iPhone 4S, iPhone 5, as well as the iPad 2, iPad 3 with Retina display, iPad 4 with Retina display and iPad Mini. It will also support the fifth generation iPod Touch.
Any other devices will be forced to stay on iOS 6, if they were compatible in the first place.
Google published its own pie chart earlier in the month. It showed that just 33 per cent of devices visiting the Google Play store are running the latest version of Android.
Many devices fall behind because handset makers release phones with heavily customised versions of Android. These need to be updated to work with the latest version.
However, few handset makers do update their phone specific versions of Android, preferring to push newer versions of their phones.
Android boss Sundar Pichai said earlier this year he is keen to address the issue with its hardware partners.
