The penetration rate of iOS by version as of January 2026 has been reported. Currently, the most used version is iOS 18, and the latest version, iOS 26, is slow to become popular.
Under these circumstances, predictions regarding new features of iOS 27, the next major version, are already being reported.
Compared to iOS 18 series, the penetration rate of iOS 26 series is only about one-fourth.
Currently, the most used iOS is the iOS18 series released in 2024, with iOS18.7 accounting for approximately 33.8%.
On the other hand, even iOS 26.1, the most popular iOS 26 series, only has a penetration rate of about 10.6%, and even when iOS 26.2 is combined, it is about 16%, which is not even close to the penetration rate of iOS 18.7 alone.
This number suggests that the migration pace of the entire iOS26 series is slower than expected.
“Liquid Glass” design receives mixed reviews
A new design called “Liquid Glass” has been pointed out as the reason why iOS26 is not becoming more popular.
Compared to the flat and clear UI of up to iOS 18, Liquid Glass has many expressions that emphasize transparency and overlapping, and the user interface has changed significantly.
While there are users who find this design appealing, it is believed that many users are holding off on updating to iOS 26 due to changes in visibility and operation feel.
Will the updated version of Siri be a catalyst for the spread of iOS26?
Another factor is that there are few “decisive moves that will make you want to migrate right away” other than design.
In the future, it is expected that iOS 26.4 will likely be equipped with an updated version of Siri with enhanced AI functions, and depending on its completeness, there is a possibility that the transition to iOS 26 will proceed all at once.
The updated version of Siri was originally scheduled to be implemented in iOS 18.4, but it is expected to be released about a year late.
Predictions about new features in iOS27
Based on this situation, predictions regarding iOS 27 have already begun to emerge. The main contents reported at this time are as follows.
・Focus on improving stability and fixing bugs rather than adding a large number of new features or making a large-scale design overhaul
・Compatible with foldable iPhone
・Improvements and adjustments to “Liquid Glass” design
・Further enhancements to Apple Intelligence
・Continuous improvement of Siri and expansion of functions for smart home displays
・Strengthen healthcare-related services
– Expanded support for satellite communication functions (maps, photo sending/receiving, third-party app support, etc.)
It seems likely that this will be an “adjusted update” that organizes and matures the new elements introduced in iOS26 while also making it compatible with next-generation devices.
