The latest Mobility Index Report from Good Technology reveals that iOS increased its lead over Android in the enterprise market during the fourth quarter on the strength of the iPhone 6 and iPhone 6 Plus. iOS accounted for 73% of total activations during the three-month period ending December, up from 69% in the previous quarter and equal to the year-ago quarter.



Specifically, the iPhone 6 and iPhone 6 Plus made up 30% of all activations during the fourth quarter, with the iPhone 6 to iPhone 6 Plus split being 77% and 23% respectively. Android activations dropped from 29% during the third quarter to 25% in the fourth quarter, while both Windows Phone and all other mobile platforms each represented a 1% share of activations.

"Device adoption varies significantly between industries, with iOS devices outpacing Android in regulated industries such as legal (95 percent), public sector (82 percent) and financial services (81 percent). Android was more widely adopted in industries with fewer regulatory compliance restrictions, such as high tech (45 percent), manufacturing (39 percent) and transportation (35 percent)."

iOS and Android activations in the enterprise were led by smaller devices during the fourth quarter, with the iPhone 6 and Galaxy S4 Mini outpacing the iPhone 6 Plus and Galaxy S4 and Galaxy S5 respectively. The report adds that secure browser activations nearly tripled quarter-over-quarter and secure instant message activations grew 900% in 2014.

BlackBerry is not reflected in this report due to its reliance on BlackBerry Enterprise Server.
