With the rumored launch of the so-called iPhone 5SE at Apple's March 15 event coming up, Mixpanel's data shows why Apple might still be looking to sell a 4-inch iPhone. The data shows that about 20 percent of current iPhone users have an iPhone 5S, 7.53 percent for the iPhone 5, and 5.66 percent for the iPhone 5C.
These numbers show that there is still a market for a 4-inch iPhone, and that a lot of people actually prefer the smaller size. That said, the latest 4-inch iPhone 5S is using over two-year old outdated tech specs, so Apple is due for an upgrade.
