Here’s a shocking revelation: despite iOS 26 being available for nearly four months, the majority of iPhone users are still clinging to iOS 18. But here’s where it gets controversial—why are so many users hesitant to upgrade? According to a recent report from 9to5Mac, citing data from Statcounter, iOS 26 adoption is lagging far behind its predecessors, with only about 16% of iPhone users making the switch. In contrast, iOS 18 remains dominant, powering over 60% of active iPhones worldwide.
Statcounter, a trusted source for tracking OS usage, paints a clear picture: as of January 2026, iOS 18.7 leads the pack with 33.8% usage, followed by iOS 18.6 at 25.2% and iOS 18.5 at 5.6%. Meanwhile, iOS 26’s adoption rates are strikingly low, with iOS 26.1 at 10.6%, iOS 26.2 at 4.6%, and iOS 26.0 at a mere 1.1%. And this is the part most people miss—this slow adoption isn’t typical. Historically, new iOS versions have seen much faster uptake. For instance, in January 2025, over 60% of users were already on iOS 18, and in 2024, iOS 17 had surpassed 50% adoption within a similar timeframe.
So, what’s holding users back? Apple’s own warnings about potential battery life impacts with iOS 26 could be a factor. Additionally, the delayed recommendation of iOS 26 as the ‘suggested’ update in Settings might have left users unsure about upgrading. There’s also speculation about concerns related to the Liquid Glass design. Is this a sign of user dissatisfaction, or simply caution?
Apple rarely shares official OS adoption numbers, leaving third-party data like Statcounter’s as our best insight. If these figures are accurate, they raise important questions about iOS 26’s appeal. Are users waiting for more stability, or is there a deeper issue at play?
