The iPhone SE is one of Apple’s best-selling smartphones, with more units sold in 2021 than the flagship 13 Pro Max. But when you compare the SE to other available iPhone models, you’ll notice that one of them is not like the others. Every iPhone Apple sells today has a notch and is missing a home button, except the SE. So why did Apple include a home button on one iPhone while leaving it out on the rest? Well it has everything to do with cost-savings. You see, the home button has been around since the original iPhone in 2007. Although it did undergo a couple revisions. In 2013 the iPhone 5s featured Touch ID built-in to the home button. This allowed the phone to be unlocked with just a tap by scanning a user’s fingerprint. The square icon was removed from the button and it went from being slightly concave to completely flat. In 2016, the iPhone 7 was upgraded to a solid-state home button. Which meant it didn’t physically click when pressed. Instead, it simulated a click by vibrating the Taptic Engine. This made the button more durable and allowed for customizable levels of force. And it’s this home button that is still being used in the iPhone SE today, nine years later. Simply because it’s cheaper to use than transitioning to swipe navigation with a notch and Face ID. In fact, the entire design of iPhone SE was simply copied and pasted from iPhone 8. A device released five years ago, to keep production costs down as much as possible. Since iPhone 8 parts become older and cheaper each year, and its assembly line was already up and running. That gave Apple enough cost-savings to drop its price from $700 in 2017 to 400 in 2020 and rename it iPhone SE. Some people like the home button and think of it as a benefit that other models are missing, but it’s really just Apple recycling old parts to keep profit margins high on their lowest-cost iPhone model.
