The graph above shows that Android brand loyalty grew in leaps and bounds in 2014 and 2015 to surpass iOS, and then grew at a slight but steady rate throughout 2016 and 2017, to reach the current 91%. iOS brand loyalty, in contrast, dropped significantly throughout most of 2014, right before the launch of the dynamic-changing iPhone 6 and iPhone 6 Plus, and then slowly started crawling back up.
“With only two mobile operating systems at this point, it appears users now pick one, learn it, invest in apps and storage, and stick with it. Now, Apple and Google need to figure out how to sell products and services to these loyal customer bases,” CIRP co-founder Mark Levin said.
The higher Android loyalty percentage, however, comes with a caveat: the actual number of Android users switching to iOS is higher than the number of users switching from iOS to Android. This is simply due to the fact that Android has a larger base of users. What this also likely means is that in the high-end phone segment, the iPhone still has the lead (you need to look no further than Apple's record quarterly profits to find a proof).
