iOS 17
The February release of iOS and iPadOS usage figures, based on apps interacting with the App Store directly, is an opportunity to see how many people update to Apple's latest mobile operating systems a few months after launch. Monday's results indicate that, compared to the year-ago figures, iOS 17 has some catching up to do.
According to the numbers, as of February 4 2024, 76% of iPhone models introduced in the last four years use iOS 17, with 20% still on iOS 16, and 4% on earlier releases. This is down from the 2023 figures, which showed 81% of devices introduced in the last four years used iOS 16 at the time, with 15% left on iOS 15, and 4% on earlier versions.
In terms of all devices that interact with the App Store, the 2024 figures show 66% of iPhones use iOS 17, with 23% on iOS 16, and 11% used earlier releases. This too is down from the year-ago numbers, which put iOS 16 on 72% of all devices, with 20% on iOS 15.
