There’s a reason the iPhone SE became Apple’s flagship phone just days after its global launch. One of the show-stopping features included is the A9 chip. The built-in A9 chip improves the SE’s performance and speed compared to the iPhone 6.
You get “desktop-level performance” with the A9 chip. The A9 has two cores, developed for the iPhone SE to be 70% faster than the 6. The graphics processing unit (GPU) is a whopping 90% faster than before. App launches are faster, data loading is smoother and because your phone performs more efficiently, you save on battery life too.
