iOS 15 Adoption Lower Than iOS 14 Over First Two Days, Says Mixpanel

Apple released iOS 15 on Monday, and in the time since, the software update has reportedly seen lower adoption than iOS 14 following its launch last year.

According to analytics company Mixpanel, around 8.5% of users installed iOS 15 as of Wednesday at 12:00 a.m. Eastern Time, compared to around 14.5% for iOS 14 as of midnight on the second day after that software update was released.

Mixpanel measures iOS adoption based on visits to websites and apps that use its mobile analytics SDKs, so the data is not official. Apple has yet to share iOS 15 adoption stats, having last reported an 85% adoption rate for iOS 14 back in June.

Earlier this year, Apple announced that iPhone users who remain on iOS 14 now have the option to continue receiving important security updates, so this change is likely contributing to iOS 15's lower adoption rate seen by Mixpanel so far.

I'd say this plays a big part:



You really have to go out of your way to install it, even with automatic updates.

The software update screen was telling me that my “iOS is up to date” at 14.8. Then a small banner at the bottom told me I could upgrade to iOS 15 too. Apple doesn’t want people to update.

I showed Live Text to some of my family members and friends - all of them updated to iOS 15 immediately afterwards.

this is happening mostly cause this time around they aren't really forcing anyone to upgrade to iOS 15 like the prior years
