Apple released new numbers on Friday highlighting user adoption of iOS 18. The mobile operating system, launched in September 2024, is currently installed on 68% of compatible devices. For iPhones released in the last four years, this number jumps to 78%.
As for the remaining iPhones, 19% are running iOS 17 and 13% are using earlier versions. Similarly, 19% of iPhones launched in the last four years are currently running iOS 17.
This number drops to 5% for early iOS builds. Not surprising given the overall percentage of devices running either iOS 17 or 18 and the tendency of early adopters to keep their devices running the latest OS updates. As 9 to 5 Mac points out, the numbers presented are similar to those released by Apple around the adoption of iOS 17 in 2024.
Apple Intelligence, the company’s small-scale model approach to generative AI, was a highlight of iOS 18. This is the first major update to the operating system, 18.1, with additional features coming in 18.2. The current public version is 18.2.1. Of course, Apple Intelligence experienced some stumbles from the start, including having to roll back the news notification summaries.
On the other hand, iPadOS 18 adoption numbers are significantly lower than its mobile version. Currently, 53% of all iPads are running iPadOS 18. This number jumps to 63% for those released in the last four years.
