Both the 4.7 inch iPhone 6 and the 5.5 inch iPhone 6 Plus suffered minimal damage when dropped on their backs. A few scuff marks here and there were the only physical result of the falls. The side test resulted in more drama. While the smaller iPhone 6 survived with some scuffs, the phablet took it on the chin. The side drop shattered the glass. And while the handset appeared to be functioning, the display was coming apart from the body.
When the iPhone 6 was dropped face first, the screen shattered pretty violently. Like the damaged phablet, the screen on the smaller model also appeared to be coming apart from the body. Despite the cracked screen, the phone appeared to be functioning fully. The Apple iPhone 6 Plus, already sporting a cracked screen, went through its front-first drop with very little additional damage to the display. In any event, it was still working although hardly usable.
The bottom line is that both models can take a hit, and still function internally. But when it comes to the screen, you are going to wish that Apple had fixed the production problems that kept it from employing sapphire glass. Be very cautious with your new iPhones, even more so than you were with older models.
Thanks for the tip!
