They improve incrementally on two already good phones. But when we spent time with them at Apple’s Cupertino event, they felt a bit anemic compared not only to other phones in their category but to their own big brother, the iPhone X. >The phones felt the same in our hands as the 7 and 7 Plus. The main difference is in texture—the back is made of glass now—meaning that fingerprint smudges were common, just like with the iPhone 4 some years ago. In fact, the Apple rep showing the phones carried a cloth with her to wipe the smudges off between demos. She wasn’t being persnickety; it was needed.
