Samsung Electronics says battery defect was cause of Galaxy Note 7 fires
After months of intense investigation,... Samsung Electronics finally reveals the cause of the fires in some of its Galaxy Note 7s.
Kim Min-ji shares with us the what the apologetic president of the tech titan's mobile division touched on at a press conference.
Samsung Electronics has concluded that batteries were the cause of some of its Galaxy Note 7s catching fire,... and not the internal structure of the handset or software. "Samsung said tests were carried out on both batteries -- both the ones used in the original phones and the ones used in the replacement devices. It concluded the fires were caused by design flaws and manufacturing issues."
In the original battery A,... provided by affiliate Samsung SDI, a design flaw in some cases triggered a convergence of positive and negative electrodes -- igniting a fire.
In the replacement battery B, which came from a different supplier,... there were welding problems, which led to a short circuit and caused the copper to melt.
Samsung also called in global companies, including Underwriters Laboratories, to conduct their own investigations -- all of which announced similar findings. "We spent the past few months analyzing what went wrong from start to finish. Although the cause was a battery defect,... we are responsible as we set the battery's specifications,... and were not able to catch the problem before the launch of the Note 7."
Last October, Samsung announced it was ending production of the Note 7 -- just two months after its launch -- following several reports of both the original and later replacement devices catching fire.
The tech giant said it has implemented a broad range of internal quality and safety procedures to prevent any recurrences.
It has also formed a group of external advisers, academic and research experts to ensure it maintains a clear and objective perspective on battery safety and innovation. "Samsung underestimated the danger of lithium batteries. Samsung is not the only case. Nokia had this problem, and you will see Apple iPhones exploding as well. But it happened much frequently in the Note 7, and that was because of constraints -- big battery in a very thin, compact device. Samsung will now thoroughly test the stability and place more margin for safety, such as sufficient space within the machine."
Experts say that while Samsung has been quick to clear up the situation in the wake of its global recall program back in September,... the tech giant will need to make sure it follows through with the lessons its learned... and work to prevent similar problems from erupting with its next release.
