manzana published updated numbers on iOS 15 adoption, confirming that its new version is not being adopted by users as quickly as the previous ones.
New Apple data reveals that 72% of iPhones released in the last 4 years are currently running iOS 15.
26% of users are still on iOS 14, while 2% are running an older version of iOS.
iOS 15 adoption numbers are lower for the entire iPhone base as only 63% of all iPhones have been updated to the new OS version.
Apple claims that 30% of all iPhones are running iOS 14, while 7% of devices are running an even earlier version.
Last year, Apple released its first update on iOS 14 adoption on December 16, saying that iOS 14 was running on 81% of all iPhones released in the last four years and on 72% of iPhones regardless of release date.
This year, Apple provided its first update on iOS 15 adoption almost a month later, and the adoption numbers are slightly lower: 72% and 63% with the same criteria.
It is important to remember that Apple Allows iPhone Users to Stay on iOS 14 and continue to receive security updates.
