Apple invited a handful of reporters to visit its iPhone testing facility in Cupertino on Thursday, to offer a peek at where and how it puts its handsets through the paces. The move comes in response to growing concerns over "bending issues" with the new iPhone 6 Plus, following this YouTube video.
The facility sits a few blocks away from Apple's Cupertino campus, and contains a lot of equipment for testing the strength and durability of the iPhone. Here, engineers for the company put handsets through a variety of tests including torsion (or twisting) and pressure, to make sure they will hold up.
