As questions mounted Thursday about the structural integrity of the iPhone 6 and in particular the 6 Plus, an Apple spokesperson reached out to CNBC to explain in some detail how the company designs and tests iPhones for durability, and to say that through Wednesday, just nine customers had contacted Apple saying their phones had bent.
It's not clear if one of those complaints came from Wired reviewer Mat Honan, who wrote in a generally positive review that his 6 Plus had bent during his review period, though he didn't remember sitting on it.
The iPhone 6 and 6 Plus "feature a precision engineered unibody enclosure constructed from machining a custom grade of 6000 series anodized aluminum, which is tempered for extra strength. They also feature stainless steel and titanium inserts to reinforce high stress locations and use the strongest glass in the smartphone industry," the spokesperson said.
Apple went on to say that workers did "rigorous tests throughout the entire development cycle including 3-point bending; pressure-point cycling; sit, torsion, and user studies. iPhone 6 and iPhone 6 Plus meet or exceed all of our high quality standards to endure everyday, real-life use."
