This number will surely sound impressive when you realize that this feat was pulled off under a month keeping in mind that the new firmware is compatible with 64-bit devices only. Furthermore, iOS 10 is currently installed on 46% of devices worldwide, but that number will surely dwindle in the time to come. What about the remaining 7%, you ask? It’s been taken up by older devices running iOS 9 or below. Still, not bad if you’re asking us.
