Apple's iOS 8.4 adoption numbers hit 40% eight days after release
16

The latest official update to Apple's iOS, iOS 8.4, was unleashed onto the world 8 days ago (June 30), and while it was mostly a maintenance, bug-fixing update, it also introduced the Apple Music music-streaming service for all devices eligible to receive the OS update. Normally, when Apple pushes a new software update for its devices, a large portion of them all are already rocking it shortly after.
This data derives from MixPanel's data regarding the Apple Music adoption. Since Apple Music comes with iOS 8.4, it's logical to deduce that the adoption rates are correlated.
