The latest numbers show that iOS 18 is doing just as well as iOS 17 did last year. According to Apple, 76% of iPhones released in the past four years have iOS 18 installed, and 63% of iPads from the same period are now using iPadOS 18.
Looking at all iPhones, 68% are running iOS 18, while 53% of iPads have iPadOS 18. However, there are still 19% of iPhones on iOS 17, and 13% on even older versions. On the iPad side, 28% are still on iPadOS 17, with 19% on older software.
This is the first time Apple has shared these stats for iOS 18 since it came out last September. For comparison, by February 5 of the previous year, 76% of iPhones released in the last four years had iOS 17, with 66% of all iPhones updated. Meanwhile, 61% of recent iPads and 53% of all iPads were running iPadOS 17.
The adoption rate for iOS 18 is similar to iOS 17, but Apple released these figures a bit sooner this year. With updates like iOS 18.3 and iPadOS 18.3 coming next week, more people might choose to update their devices.
Also, expect some big Siri updates in the iOS 18.4 update coming in April, which could boost the number of users even more. iOS 18 supports iPhones up to six years old, starting from the iPhone XS/XR. However, the fancy new Apple Intelligence features are only for the iPhone 15 Pro and iPhone 16, which might make some people with older phones think twice about upgrading.
