iOS 18 Installed on 76% of iPhones Introduced in the Last Four Years

iOS 18 adoption is on pace with iOS 17 adoption last year, according to ‌iOS 18‌ adoption statistics provided by Apple. ‌iOS 18‌ is installed on 76 percent of iPhones introduced in the last four years, while 63 percent of iPads from the last four years are running iPadOS 18.

iOS 18 on iPhone Feature
68 percent of all iPhones have ‌iOS 18‌ installed, and 53 percent of all iPads have ‌iPadOS 18‌ installed.

For all iPhones, 19 percent are still running iOS 17 and 13 percent are running an earlier version of iOS. For all iPads, 28 percent are running iPadOS 17 and 19 percent are running an earlier version of iPadOS.

This is the first time that Apple has provided insight into ‌iOS 18‌ adoption numbers since the operating system was released last September.

Last year, iOS 17 was installed on 76 percent of iPhones from the last four years as of February 5, with 66 percent of all iPhones running the update. 61 percent of iPads from the last four years had iPadOS 17 installed, while 53 percent of all iPads were running the software.

‌iOS 18‌ adoption is about the same as iOS 17 adoption, but it is worth noting that Apple is sharing the numbers slightly earlier this year. iOS 18.3 and iPadOS 18.3 are expected to see a launch next week, which could push more people to upgrade to the operating system.

Major new Siri features are also coming to Apple Intelligence-compatible iPhones with an iOS 18.4 update that's expected in April, so ‌iOS 18‌ adoption could see another major jump at that time.

‌iOS 18‌ is available to iPhones that are up to six years old, as it is compatible with the iPhone XS/XR and later. Apple Intelligence features are limited to the iPhone 15 Pro and iPhone 16 models, however, which could discourage some ‌iPhone‌ users with older devices from updating.

Many users on various online boards said that they're staying with their older iphones with older stable iOS versions, like 17.x.x.
Many are willing to wait until iOS 18 later, though playing the wait game doesn't help as iOS 19 to be released supposedly later this year.
I wish I could go back but Apple made it impossible ?

Nah. The vast majority are like my elderly parents. They don't know or care about what is in the updates. They just have "a phone" and/or "tablet" and use it as a tool. They update as soon as the device badgers them into doing so via an on-screen notification. It takes a certain amount of tech knowledge to have reasons to delay the update.
