It has been reported today that iOS 15, which was only released to the public 80 days ago – is now installed on 58% of all iOS devices out there. This data has come from Mixpanel, a third party data analytics company. Apple hasn’t yet released any data on adoption figures for iOS 15, the last time the company said anything was back in June 2021.
In June, Apple reported that around 85% of its devices out in the wild were running iOS 14.
iOS 15 was announced in June this year, at WWDC and was then made publicly available to customers in September.
