iPhone 6 Plus Bending: Apple Reveals Its Own Stress Tests

With the iPhone 6 Plus getting mocked all over social media over suggestions it can be bent rather easily, Apple responded by inviting journalists to observe its testing procedures.
According to Apple, 15,000 iPhone 6 and as many iPhone 6 Plus handsets were stress tested before the two models were sold to consumers. Journalists from publications such as the Wall
Street Journal, Re/code and The Verge were taken to see these
facilities, and shown the tests in detail.
Re/code has a
video showing all the tests, and in case you can't watch the video
embedded here, we've also described them for you below.
The
first test that Apple puts phones through is called a sit test, which
is supposed to replicate the pressure on the phone when you're sitting.
This is what has resulted in the reports of bent iPhones, and Apple
tests for the pressure of a typical user sitting down on a hard surface,
then sitting on a soft surface, and finally, sitting on a hard surface
at an angle, which was described as the worst case scenario for your
phone. The test uses a 25kg weight to apply pressure, and the iPhone 6
Plus that was tested in front of the journalists was not damaged by
this.
Apple then puts the iPhone 6 and iPhone 6 Plus
through a 3-point bend test, where 25kg of weight is pressed across the
centre of the iPhone. The whole width of the phone is pressed by the
bar, while 2 similar bars hold up the edges. That's similar to holding
the edge of the phone with your fingers, and pressing at the centre with
your thumbs. In this test, the reporters saw the iPhone bend, but
return to its normal shape. According to Apple, if a huge pressure is
applied on the phone then beyond a certain point the deformation can
set.
Another test is the pressure point test, where a
strong pressure is applied directly to the centre of the iPhone. The
10kg pressure is applied in a single point.
Finally, the
phone is put through a torsion test, where Apple showed an iPhone 6,
iPhone 6 Plus and a MacBook Pro being twisted from both ends. While
these were the only tests demonstrated, Apple (and all companies) put
their phones through a much larger series of tests to ensure that there
are no physical defects with their designs and materials.
That's a very small number compared to the 10 million handsets that Apple says it sold, but as more people use their phones, it's likely that the reported problems will also rise.
