Here are the countries where the Apple iPhone SE is selling well23
The data shows a lower adoption rate for the iPhone SE when compared to the Apple iPhone 6 series, the Apple iPhone 6s series, the Apple iPhone 5s and Apple iPhone 5c. Some theorize that this is due to the nature of the beast; the iPhone SE is a phone that one keeps in the recesses of his or her mind as a replacement for some down the road event like an upgrade or a broken handset. That is in opposition to the other iPhone models which were aimed at consumers looking to buy a new phone now, or those who had to have the latest iPhone at that moment.
To read the specs of the iPhone SE is to understand more clearly what this device is all about. Despite the 4-inch screen, it is powered by the same A9 chipset that drives the Apple iPhone 6s and Apple iPhone 6s Plus. It also has the same 12MP rear snapper found on the iPhone 6s, and even includes Live Photos despite the lack of 3D Touch. The Touch ID sensor is from the previous generation, which makes it a tad slower. And with support for NFC and Apple Pay, this is the perfect phone for those who have been sitting with an older 4-inch model and want to upgrade the hardware.
There are a ton of iPhone users who never upgraded to the larger screen of the Apple iPhone 6 or Apple iPhone 6s. Now, these holdouts have the opportunity to keep the smaller screen they love without missing out on many of the hardware changes. Of course, this ends in September when the Apple iPhone 7 comes to market with the A10 chip, possibly a new modem supplier, and other hardware upgrades. As such, we'd expect to see the iPhone SE receive a nice price cut when the next iteration of the iPhone is released.
