Courtesy of Apple, this data exemplifies just how much more efficient Cupertino's approach is when it comes to software updates. A quick Google search returned rather shocking results for the Android camp: only a lousy 0.3% of the world Android population is on the latest Marshmallow update. That's despite Android 6 being released shortly after iOS 9. In fact, even Android 5 Lollipop accounts for just 26% or so of the population, while Android 4.4 KitKat is the leader with a 38% share. That's software released over two years ago.
There's a score of reasons for Android's crappy performance in this area, and the majority of them are very much justifiable — specifically considering the overall quite positive effect the OS has had in terms of making smartphones nearly universally affordable. Nevertheless, a fragmented ecosystem benefits no one and can potentially even endanger users on older software, despite Google's efforts in decoupling a wide array of services from the core in order to be able to push timely updates to them.
