Apple's iOS 9 mobile operating system is now installed on two out of each three iPhone, iPod touch and iPad devices in the wild just a little over a month and a half following its September 16, 2015 release.
According to the official stats available through the company's App Store dashboard for developers, iOS 9 is now powering 66 percent of Apple's mobile devices in active use versus the adoption rate of 61 percent recorded just two weeks ago.
