Not content with selling a whopping 13 million iPhone 6s handsets in their first weekend on sale, Apple is also smashing records with iOS 9 adoption.
According to Apple’s latest developer figures, just three weeks after its public debut, 57 percent of users with compatible mobile devices are already running iOS 9. Meanwhile, 33 percent are still using the last-generation iOS 8, while just 1 in 10 users is stuck on an earlier version.
