Apple reported today that 66% of all iPhones currently in use are running iOS 26, the company’s latest operating system. The data, based on iPhones and iPads that connected to the App Store as of February 12, 2026, indicates a relatively steady adoption rate compared to previous major iOS releases.
Specifically, Apple stated that 74% of iPhones introduced within the last four years have been updated to iOS 26. For iPads, 57% of all devices and 66% of those released in the past four years are now running iPadOS 26.
These figures are comparable to adoption rates for iOS 18, which, as of January 21, 2025, was running on 68% of all iPhones and 53% of all iPads. Four-year-traditional device adoption for iOS 18 stood at 76% for iPhones and 63% for iPads.
Looking back to February 4, 2024, iOS 17 had reached 66% of all iPhones and 53% of all iPads, with 76% and 61% adoption respectively among devices released in the preceding four years.
The release of iOS 26, which debuted in September 2025, introduced a significant visual redesign termed “Liquid Glass,” altering the translucency and fluidity of system elements. The update also included new communication features, such as customizable backgrounds in Messages and Call Screening, as well as enhancements to the Lock Screen, Photos, and a dedicated Games app, according to Apple’s initial announcement.
Recent reports suggested that iOS 26 adoption was lagging, fueled by data from third-party analytics firms. However, these claims were disputed, with analysis pointing to Apple’s deliberate phasing of automatic updates. Apple has, in recent years, encouraged automatic updates but typically delays the broad rollout of major iOS versions to allow for bug fixes and stability improvements. This year’s rollout experienced a delay of approximately two weeks beyond the typical two-month post-release period, followed by a third wave beginning in January.
According to sources, Apple’s approach is driven by the complexity of iOS 26, which is considered a more substantial and, initially, more prone to issues than iOS 18 or 17. The company appears to be prioritizing a stable user experience over immediate widespread adoption.
The company has not commented on the reasons for the phased rollout, and has not released any further statements regarding adoption rates beyond the figures shared today.
