Even though Samsung had recalled the Samsung Galaxy Note 7 twice because of explosions, and eventually pulled the phablet off of the market, the company at first was unable to duplicate the explosions in the lab . But today, a new report says that Samsung has figured out exactly what caused the problems with Galaxy Note 7 battery that cost the company a reported $5 billion in lost revenue and other costs.
Samsung says that it has shared the results of its internal investigation with UL and the Korea Testing Laboratory. And while the company has promised to release a report detailing the exact cause of the explosions by the end of this year, so far the company is not yet ready to share the results of its investigation with the public.
At the beginning of this month, a report blamed the design of the battery used on the Galaxy Note 7 for causing the explosions and fires. As the report points out, compressing the battery would force the positive and negative layers to squeeze together. Samsung itself said that it might have been too aggressive with the design. In addition, there is a normal amount of swelling that takes place. Some of it comes from the pressure on the battery created through pushing on the back cover (for example, by putting the phone in one’s back pocket and then sitting on a chair).
In order to make the phone thin, the batteries were designed to be carry as much capacity as possible, while keeping to a svelte footprint. The report stated that if the phablet had not been recalled, the body of Galaxy Note 7 units throughout the world would probably have separated.
Samsung reportedly wanted a thin battery with as much energy capacity as possible in order to maintain the phablet’s thin design and long battery life. This, to me, is somewhat an impossible task and an act of greed on Samsung’s part. You don’t achieve greatness without giving up some things. Apple for example wanted an ultra slim iPhone 7, they had to give up the traditional 3.5mm earpiece jack to achieve such. Sacrifices have to be made!
