iPhone 5 set a precedent. Apple engineers and designers managed to compress first-of-their-kind technologies inside a space that’s a mere 7.6 millimeters thin and 112 grams light.
A feat like that required designing or redesigning multiple components. And it resulted in an incredibly thin, impressively light, extraordinarily powerful smartphone. After coming so far with iPhone 5, it was a perfect place to start with iPhone 5s.
And while the engineering challenge was significant, we succeeded in adding more to it without making iPhone 5s bigger or heavier.
