We have all heard or seen on the news the infamous story of Samsung Galaxy Note 7 exploding. As such the Korean Smartphone manufacturer had to recall the devices which ultimately hit their finances lowering the company's profit immensely. Not only that, Samsung lost the trust of their customers.
While this has been a nightmare for the company, Samsung has not yet released results of its investigation into the Galaxy Note 7 battery explosion fiasco as there is no official explanation yet.
However, while we are still waiting for the official disclosure, a report from the manufacturing company Instrumental shows the real reason behind all the explosions.
While working behind the scenes and performing a teardown of a defected Galaxy Note 7 with a fire extinguisher by the side, the manufacturer found out that the aggressive design strategy of cramming the biggest possible battery into the smaller frame had caused the Galaxy Note 7 to explode.
Thus, the design of the device was in fact fundamentally flawed and the battery also didn't have enough breathing space or room.
Moreover, the slimness of the design had led the battery to get more compressed even during normal, non-intensive functions. Ultimately leading to the battery getting overheated.
So when more aggressive functions were conducted it completely led to an additional compression of the battery thus resulting in the phone exploding. As such the batteries themselves weren't faulty, rather, Samsung's push to make the case as thin as possible likely comprised them.
Going more into detail, the reports states that by compressing the battery it had put more pressure on those critical polymer separator layers that keep the battery safe.
Due to aggressive manufacturing parameters that Samsung had taken, the separator layers had failed to do the job and thus causing the battery to explode.
Samsung engineers were clearly trying to balance the risk of a super-aggressive manufacturing process to maximize capacity while attempting to protect it internally. The report analyzes that Samsung had taken a deliberate step towards danger, and their existing test infrastructure and design validation process had failed them.
Although we are yet to receive the official statement from Samsung, this report looks to clear some air regarding the sad demise of the Galaxy Note 7 which was to be the device that dethroned Apple and was the competition for Apple iPhone 7.
