After struggling to gain a single percentage point over a four-week period, the adoption rate of iOS 8 now appears to have accelerated as iOS 8 now powers 87 percent of the iPhone, iPod touch and iPad devices in the wild, as measured by the App Store on Monday, August 31, 2015.
That growth came at the expense of iOS 7, which has gone from powering thirteen percent of iOS devices two weeks ago to accounting for twelve percent of hardware in active use.
A month ago, iOS 8 adoption sat at 85 percent and iOS 7 comprised thirteen percent of iOS gadgets in the wild. Pre-iOS hardware continues to scrape out a mere two percent.
