Following the scandal generated by the discovery of the fact that iPhone 6 bends si iPhone 6 Plus bends, company Apple published a press release last evening announcing that only 9 customers complained about this problem. Because a press release is not enough, the company Apple Lossless Audio CODEC (ALAC), invited American journalists in the laboratory where they test the resistance of all products to be launched on the market.
The tour of the testing laboratory was made by Dan riccio, the senior vice president of the hardware division, and there the journalists could see exactly how the company tests Apple Lossless Audio CODEC (ALAC), every product to be launched on the market. With the help of the machines in the images, Apple bends and hits its products in every possible way to see how resistant they are in case of knocks or falls, correcting any problems before launching them on the market.
Apple still claims that if iPhone 6 it bends or if 6 iPhone Plus it bends, any terminal can be taken to a Apple Store to be inspected and replaced if the bend is not caused by the user. And finally, the 5 testing methods used by Apple:
- applying pressure in 3 points;
- To make sure new iPhones can handle "reasonable" force, Apple puts pressure on the device at three different points along the frame.
- applying pressure in various key points by repeating the cycles;
- The pressure-point cycling tests place "substantial" force across an iPhone's display and encasing, while it is held along its edges, to ensure that an iPhone can be bent and pushed many times over during its lifespan. Apple runs this test hundreds of times to ensure durability.
- torsion test;
- The iPhone is twisted and turned like a piece of licorice about 8,000 times. "The company does this to make sure its devices can handle twists and torque in various situations, such as sitting on an iPhone unevenly."
- placement tests on terminals;
- An engineer sits down thousands of times with the iPhone pocketed in every imaginable position. What a job.
- and finally the studies done in the real world with users.
- First was the "sit test." Dan Riccio, Apple's senior vice president of hardware engineering, says this test is the one that is most relevant for customers with concerns about the phones bending in pockets. There are three parts to the sit test. The first part simulates a typical user sitting down on a hard surface, the second simulates someone sinking into something softer like a couch, and finally there's what Riccio calls a "worst-case" tests, where someone would have a phone in their pocket and sit down on a hard surface at an angle.
Three-point bending: Apple's tests place pressure on iPhones in varying degrees to make sure they can handle "reasonable" force in various situations.
Pressure-point cycling: The pressure-point cycling tests place "substantial" force across an iPhone's display and encasing, while it is held along its edges, to ensure that an iPhone can be bent and pushed many times over during its lifespan. Apple runs this test hundreds of times to ensure durability.
Torsion testing: Apple clamps down an iPhone at both ends and twists the handset about 8,000 times. The company does this to make sure its devices can handle twists and torques in various situations, such as sitting on an iPhone unevenly.
Sit tests: A single phone is placed into simulations reflecting real-life scenarios, such as being in the back pocket of tight jeans. Phones are sat on, against a hard surface, thousands of times and in multiple positions in a pocket. Sit tests cover both orientations of the glass screen—facing out and facing in.
Real-life user studies: Another part of testing involves real humans, hundreds of company employees live with and use the phones in various situations to test for both durability and performance. Employees who have the highest usage rates on their phones are selected to take part, and Apple methodically checks the phones for any issues as they're being used.
