iOS 8 continues declining as a result, dropping from 22 percent two weeks ago to 21 percent of iOS hardware as of yesterday, indicating that much of iOS 9’s growth in the 14-day period came from users upgrading to iOS 8 and new iPhone buyers.

Earlier versions of iOS, meaning iOS 7 and older, continue to make up eight percent of activedevicesin the wild. A month ago, iOS 9 was detected on 67 percent of devices, indicating that adoption of Apple’s latest and greatest operating system may be slowing a bit ahead of the crucial holiday season.

According toGoogle’s own dashboard for Android developers, Android 6.0 Marshmallow waspowering0.5 percent of active Android smartphones and tablets in the wild, as captured in the Play Store access logs during a 7-day period ending on December 7, 2015

Android Marshmallow has been available for a little more than two months now. If you put together Android Marshmallow, Lollipop and KitKat editions, these three accounted for 66.6 percent of Android 2.2 and later hardware, excluding devices sold in China and elsewhere that don’t ship preloaded with Google’s services and Play Store.
