Apple Disclosed iOS 17 Adoption Numbers Prior to WWDC24: A Good Sign for iOS 18?

Toggle Dark Mode
Apple shared the latest adoption statistics for iOS 17 and iPadOS 17 before WWDC 24 started. Apple calculates these statistics based on the iPhones and iPads that transacted on the App Store on June 9, the day before WWDC kicked off.
Apple shared that 86% of all iPhones introduced in the last four years and 77% of iPhones overall have upgraded to iOS 17. As for iPads, 77% introduced in the last 4 years were using iPadOS 17 and 68% of all iPads have upgraded to the latest iPadOS. Interestingly, 14% of all iPhones are still using iOS 16, while 9% are using an even earlier version of iOS. 17% of iPad users are still using iPadOS 16 while 15% are using an older version of iPadOS 16.
Around the same time last year, Apple shared that iOS 16 adoption reached 81%, while only 53% of iPads were running iPadOS 16. The pace of both iOS 17 and iPadOS 17 adoption has been faster than for iOS 16 and iPadOS 16.
Overall, iOS and iPadOS 17 adoption rates offer an important predictive lens through which Apple can anticipate and plan for the release of iOS and iPadOS 18. Apple’s goal is to maximize user satisfaction and engagement with iOS 18, which will hopefully lead to even faster adoption than iOS/iPadOS 17.
One alarming statistic is the overall number of iPhones and iPads that haven’t upgraded beyond iOS/iPadOS 16 or are using even earlier versions. 23% of all iPhones and 32% of all iPads haven’t yet made the leap beyond iOS 16 and iPadOS 16. These numbers suggest the biggest threat to iOS/iPadOS 18 could be device compatibility. While we don’t know for sure, it’s possible many of these users will need a new device to enjoy Apple’s latest and greatest operating systems. Maybe that’s why we’ve seen Apple increase trade-in values towards a new device.

If your device isn’t on the list, maybe you’re among the users who have yet to try iOS 17. It might be worth exploring trading in your device or selling it via third-party retailers and upgrading. Keep an eye out for carrier deals as well. Given the hype around iOS 18, we expect Apple to continue to encourage trade-ins and carriers to offer more promotions. iOS 18 is packed full of new features and will mark a new era for iOS and artificial intelligence.
