Despite being on the market, the Samsung Galaxy Note 7 saw truncated its triumphant launch in summer of 2016 by a problem with the batteries. After a partial withdrawal from the market in mid-September, Samsung ended up announcing the total withdrawal of the store model in October of the same year.

The culprit, according to the matrix, is twofold: in the first set of batteries analyzed was due to the mechanical compression in the upper right of the batteries between the separation layers of the anode and the cathode. The error detected in the second group of batteries would be in a pinch in these same layers made possible by the micro-soldering process that caused a short circuit.

The batteries, manufactured by Chinese company ATL for “Note 7” sold in China, and by Samsung SDI in most countries. Samsung SDI is the division of the conglomerate in charge of manufacturing electronic components for Samsung Electronics as well as for other manufacturers like Apple, Sony or Tesla for batteries of energy storage in homes and businesses.

Samsung SDI is one of the largest battery manufacturers in the world along with the Japanese Panasonic or the also Korean LG Chem. The announcement of the investigation was carried out by DJ Koh, leader of the mobile devices division of Samsung Electronics after apologizing to customers, partners and operators. In their analysis, they created a great station of load and discharge of Galaxy Note 7 where they could reproduce the causes. Samsung performed thousands of tests with fast and normal charge, wireless and traditional, as well as different voltages. The Koreans even tried to apply strong current discharges onto the USB-C of the device. None of these tests yielded out-of-the-ordinary results.

The Seoul-based conglomerate began a far more ambitious investigation after the final withdrawal, to satisfy both the questions of safety regulators around the world and to assure them that a similar ruling would not happen again in their next models.

The manufacturing error is estimated in terms of direct and indirect costs such as depreciation of the brand image that influences other terminals that will not be sold in the long term, between $3,000 and $17,000. A large part of these losses were already taken over by Samsung during the previous financial quarter, reducing its profits to just $ 87 million in exchange, a 95% reduction compared to the previous quarter.

But from Seoul they want to leave behind their recent past starting 2017 with a big foot. According to the financial analysts, Samsung will present a closing of the fiscal year of 2016 with quarterly data of record. The company is already preparing to unveil to the world the Galaxy S8, the successor to the successful Galaxy S7. Although there is no official announcement of Galaxy Note 8 in the future, many buyers of the retired smartphone will welcome to ride the Galaxy S8 car when it is presented in the Spring.
