Over half of iPhones and iPads are now running iOS 11, after the software debuted back in September.
The official figure of 52% represents the first time that Apple has revealed how many devices are using the latest version of iOS 11. Until now, stats have come from third-party analytics companies.
38% of iPhones and iPads are still using 2016’s iOS 10, with the remaining phones and tablets using older editions.
The official figures show that iOS 11 adoption has been much slower compared with iOS 10 last year.
It’s not clear why this is, although a combination of concern about updating following problems with iOS 10 in the wake of its launch, plus a number of key features still missing from iOS 11, are likely to blame.
Apple has launched Apple Pay Cash with its latest beta edition of iOS 11, with iCloud Messages still not ready for release.
iOS 11 brings a number of design tweaks, including a new control centre.
