As of April 22, iOS 11 is now installed on 76% of devices, an 11% increase since January 18 – this was shared by Apple today on its App Store Support Page.
As pictured above, 19% of devices are still running iOS 10, and only 5% any earlier operating systems (iOS 9 and earlier). Many of these devices are likely to be out of date and unable to run the latest iOS editions.
This uptake, whilst impressive, is surprisingly less than that of iOS 10, which was installed on nearly 80% of devices in February of 2017. This is due to the large number of bugs that have plagued iOS 11 since it’s release, dissuading a relatively large number of users from upgrading. Also, Apple’s throttling of performance on older iPhones, though not necessarily completely tied to iOS 11 – will likely be another reason for this slow uptake.
The new influx of updates is almost completely as a result of the iOS 11.2 and 11.3, both of which were major updates in terms of features and received a lot of good press.
iOS 11.2 brought with it Apple Pay Cash and faster 7.5W wireless charging for Apple’s latest iPhones with wireless charging capabilities. More recently, iOS 11.3 introduced the new battery health tool, a Health Records feature, AR Kit 1.5 and a variety of small changes.
iOS 11.4 is expected to include Messages on iCloud and AirPlay 2, both features reportedly being tested by Apple, according to MacRumors.
