Apple released new figures Friday, highlighting user adoption of iOS 18. Released in public form back in September 2024, the mobile operating system is now installed on 68% of compatible devices. That number jumps to 78% on iPhones released in the last four years.
As for the remaining iPhones out there, 19% are running iOS 17 and 13% are using an earlier version. Similarly, 19% of iPhones released in the last four years are currently running iOS 17.
The figure drops to 5% with earlier iOS builds — understandable, given the overall percentage of those devices that shipped with either iOS 17 or 18, along with early adopters’ propensity to keep their devices running the latest OS updates. As 9 to 5 Mac points out, the figures presented are similar to those Apple issued in 2024 around iOS 17 adoption.
The company’s small model approach to generative AI, Apple Intelligence, was the marquee feature for iOS 18. That arrived with the operating system’s first major update, 18.1, with additional features arriving with 18.2. The current public version is 18.2.1. Of course, Apple Intelligence has had some stumbles out of the gate, including one that required the company to roll back News notification summaries.
Meanwhile, iPadOS 18’s adoption figures are markedly lower than its mobile counterpart. Currently, 53% of all iPads are running iPadOS 18. That figure jumps to 63% for those released in the last four years.
