Apple appears to have improved the durability of the iPhone 7 compared to the iPhone 6s, as highlighted by a new drop test video by EverythingApplePro. The iPhone 7 does very well in this specific test, sustaining ten foot face-down and side drops without cracking the screen. In contrast, the iPhone 6s was completely shattered at drops of five-feet. The iPhone 7’s rear sapphire cover glass (the camera bump) was damaged but the person could still take photos.
Apple makes no claims about drop or shatter performance of course; the waterproofness of the iPhone 7 has already been shown to be of a high-standard.
