New figures from CIRP reported inĀ Fortune show that Apple wins three times as many smartphone customers from Samsung as Samsung does from Apple: 20 percent switched from a Samsung handset to an iPhone, while only 7 percent switched in the opposite direction.

Unsurprisingly, the biggest chunk of iPhone buyers – 42 percent – were upgrading from a previous iPhone, while the rest were split between those switching from other brands (around 30 percent) and those upgrading from a featurephone (26 percent) – with a handful of first-time cellphone buyers making up the rest.

With iPhone prices higher than the average for Samsung’s range of smartphones, it’s also no surprise to see that the educational attainments of iPhone owners tend to be higher, this being a rough proxy for income.
