What Caused the Samsung Note 7 Explosions

Samsung’s probe into its Galaxy Note 7 fiasco has found that the overheating and burning of the phones was caused by faults with their batteries. The firm had axed its iPhone rival in October last year after an earlier botched recall and re-release.The recall is thought to have cost $5.3bn (£4.3bn) and was hugely damaging for the South Korean firm’s reputation. On Monday, Samsung said that neither software nor hardware were at fault, only the batteries.

Samsung Galaxy Note 7 (marketed as Samsung Galaxy Note7) is a discontinued Android phablet smartphone that was produced and marketed by Samsung Electronics. Unveiled on 2 August 2016,it was officially released on 19 August 2016 as a successor to the Galaxy Note 5. Although it is the sixth main device in the Galaxy Note series, Samsung branded its series number as “7” instead, so that consumers would not perceive it as being inferior to the flagship Samsung Galaxy S7.

 

Internal and independent investigations “concluded that batteries were found to be the cause of the Note 7 incidents”, the South Korean technology giant said in a statement.Samsung Electronics saw profits surge 50% in the last three months of 2016, despite the Note 7 phone fiasco.

The 9.2 trillion won ($7.2bn; £5.8bn) quarterly profit is the South Korean firm’s highest since 2013.In October, the smartphone maker had to scrap the Note 7, after recalling 2.5 million handsets. Batteries were blamed for phones catching fire.

Following an investigation that took months, Samsung Electronics has revealed the root causes behind those exploding Note 7 phones: design and manufacturing flaws associated with the lithium-ion batteries used in the phones, which were produced by Samsung’s battery suppliers.

The company released the findings at a press conference in Seoul late Sunday.Samsung conducted its own internal investigation to determine why some of the devices caught fire, and hired the UL safety consulting firm and the Exponent engineering and scientific consulting firm to conduct their own independent tests. Another independent firm, Germany’s TUV Rheinland, was brought on to assess Samsung’s factories and logistics.

 

 

the first problem affected the first batch of Note 7 phones that launched last fall. In those phones, the battery was too large for its casing, causing some devices to overheat, according to Samsung’s report.Recalling the initial batch of Note 7 phones, Samsung manufactured the phone with a battery from a different supplier. But Samsung was in a rush to get the new phones out, and the new battery produced by the supplier had a defect that also caused it to overheat, the report said.

So what was the Cause?

BBC made this report that “The company said that errors both in design and manufacturing affected batteries by two different manufacturers.According to the findings, the problems centred on insufficient insulation material within the batteries and a design that did not give enough room to safely accommodate the batteries’ electrodes”

 

So what is the Way Forward?

Since the fall of Note 7 caused the company massively which in turn brought questions about the brand. Due to this the investigations also made way for how the situation will not happen again.

Samsung says it has developed a new eight-point battery check to make sure future devices don’t suffer the same fate as the Galaxy Note 7. The test includes an X-ray of the phone and extreme testing conditions that force the battery to work harder than normal.

The company also formed a new group of third-party battery advisers that includes professors from the University of Cambridge, the University of California at Berkeley, and Stanford University.
