Mobile OS version adoption

While trying to understand adoption patterns of new mobile OS versions, I decided to plot data from the Android Dashboard and Apple’s pie-chart, with help from the Wayback Machine. I’ll try to keep the charts updated going forwards. Feel free to hover; they are interactive. The charts confirm our common knowledge: new Android versions take long to reach a reasonably good share of the userbase compared to new iOS versions where 70% adoption is reached within a month. »
