Originally launched in March 2016, Apple's iPhone SE served as the smaller, more pocketable member of the iPhone family. It was Apple's compact, budget option, and its 4-inch screen and tinier overall size were total throwback stuff. Consumers loved the battery life and that it still had a headphone jack -- an option Apple started killing off starting with the iPhone 7 in 2016.
