Which iPhones Are Affected By iOS 26?
The latest software, iOS 26, follows iOS 18, which was compatible with iPhones from the iPhone XS, XS Max, and XR onward. However, these three models cannot upgrade to iOS 26. All other models from the iPhone 11 onward are eligible for the latest update, making them crucial for users to consider. Below is the complete list for reference.
Understanding Apple iOS 26 Update Cycles
Apple typically follows a predictable pattern: every September, new iPhones are launched alongside the latest software cycle. iOS 26 has now replaced iOS 18. To accommodate users who prefer waiting on new software, Apple released alternative updates for the first few months. With the arrival of iOS 26, iOS 18.7 and its subsequent update to iOS 18.7.1 were made available. However, after the early November releases, users anticipated a similar pattern, which changed when iOS 18.7.3 was released exclusively for the iPhone XS, XS Max, and XR.
Why Hundreds of Millions Must Upgrade to iOS 26 Now
Since December 12, hundreds of millions of iPhones have been required to upgrade to iOS 26 or remain on outdated software. This is particularly critical as iOS 26.2 includes essential security updates. If you own an iPhone XS, XS Max, or XR, iOS 18.7.3 is available, and it’s highly recommended to update without delay.
Upcoming Updates and Their Implications
It is likely that the upcoming release of iOS 26.3 will be accompanied by iOS 18.7.4, specifically for the XS, XS Max, and XR models. Unless Apple alters its course, these updates will not extend to newer devices. Prior discussions about an interim security update, iOS 26.2.1, appear to have fallen through, emphasizing the urgency to upgrade to the latest version.
The Importance of Upgrading for Your iPhone
If you have delayed upgrading to iOS 26, now is the time to act. Although there were valid concerns about the new software design, especially for users with low vision, the benefits of updated security measures and features greatly outweigh them. Don’t hesitate—upgrading to the latest software is crucial for maintaining device integrity.

The following iPhone models are compatible with iOS 26: iPhone 11, iPhone 11 Pro, iPhone 11 Pro Max, iPhone 12, iPhone 12 Mini, iPhone 12 Pro, iPhone 12 Pro Max, iPhone 13, iPhone 13 Mini, iPhone 13 Pro, iPhone 13 Pro Max, iPhone 14, iPhone 14 Plus, iPhone 14 Pro, iPhone 14 Pro Max, iPhone 15, iPhone 15 Plus, iPhone 15 Pro, iPhone 15 Pro Max, iPhone 16, iPhone 16 Plus, iPhone 16 Pro, iPhone 16 Pro Max, iPhone SE (2nd generation), iPhone SE (3rd generation), and iPhone 16e.
