Slow iOS 26 Adoption
Usage data published by StatCounter (via Cult of Mac) for January 2026 indicates that only around 15 to 16% of active iPhones worldwide are running any version of iOS 26 . The breakdown shows iOS 26.1 accounting for approximately 10.6% of devices, iOS 26.2 for about 4.6%, and the original iOS 26.0 release at roughly 1.1%. In contrast, more than 60% of iPhones tracked by StatCounter remain on iOS 18, with iOS 18.7 and iOS 18.6 alone representing a majority of active devices.
Historical comparisons highlight how atypical this adoption curve appears. StatCounter data from January 2025 shows that roughly 63% of iPhones were running some version of iOS 18 about four months after its release. In January 2024, iOS 17 had reached approximately 54% adoption over a similar timeframe, while iOS 16 surpassed 60% adoption by January 2023.

In the first week of January last year, 89.3% of MacRumors visitors used a version of iOS 18. This year, during the same time period, only 25.7% of MacRumors readers are running a version of iOS 26 . In the absence of official numbers from Apple, the true adoption rate remains unknown, but the data suggests a level of hesitation toward iOS 26 that has not been seen in recent years.
I want to believe this is because people are choosing to avoid Liquid Glass, but the difference in curves is so stark that I assume it must be due to a measurement problem or a change in how strongly iOS’s Software Update is pushing new versions.
This, even given that Apple has made the 18.7.3 installer [and its security fixes] unavailable for anyone not an Apple Developer and in the beta program.

I've found it surprisingly easy to stay on iOS 18.
Regular people are already sick of AI hype and, understandably, believe they'll be less annoyed by it by staying on an older OS.
Even non-nerds are at a stage of their lives where their phone does what they need it to do and they also actually really need it to work.
In your digital life, putting security concerns aside, when was the last time something really great came from an update? On any platform?
An update is now simply an invitation to make your working phone not work anymore.

"UPDATE: My iPhone running iOS 26.3 is detected by StatCounter’s user agent detection tool as an iOS 18.7 device. This reflects how StatCounter says is how it collects its figures. Two other devices running iOS 26 were also detected by StatCounter as iOS 18.7 devices; however, on one of them in the Chrome browser, StatCounter correctly detected it as iOS 26.1. I also see this effect in my own limited analytics, where the only reports of iOS 26 versions are non-Safari browsers. If an analytics package relies on the OS version string in the user agent, it will also misreport iOS 26 Safari users."
I wonder if all of this comes back to bite indie devs in particular. For the past years it’s been fine to just support the latest two iOS versions. Is this about to change with iOS 27, if a significant number of holdouts stay on iOS 18, and we’ll have to keep supporting that for years to come?
I usually wait to upgrade until the third major update. Will wait longer this time. Possibly to 27.
Also just realized we have had a preview of iOS 26 extreme corner radius all along in iOS 18 Shortcuts dialogues. Ugly.
@Nicholas Piasecki: indeed. worse yet, iOS 26 is a degradation so from a user's point of view upgrading makes no sense. The same can be said for a hardware point of view, there is no upgrade path from my iPhone 13 mini, nor do I -battery aside- need one.
I subscribe to Michael's desire to believe in rebellion, but it has to be a measurement error.
