January 2017, 3 months after the recall of the Galaxy Note 7 in October of 2016 (Story of recall found here: Samsung7 Recall Goes Global), Samsung has released their findings as to what has made their Galaxy Note 7 spontaneously overheat and explode.
After testing over 200,000 devices and 30,000 batteries a Samsung team of 700 company engineers concluded that the overheating was caused by separate problems in batteries sourced from two different suppliers.
In the case of batteries supplied from the Samsung SDI, the heat sealed protective pouch around the battery didn’t have enough room and would crimp the battery causing a weak connection and short circuiting.
In the case of batteries sourced from Amperex Technology Limited, components of the battery were either missing or manufactured wrong, leading to damaged or thin separators.
“We are taking responsibility for our failure to identify the issues arising out of the battery design and manufacturing process prior to the launch of the Note 7,” Samsung mobile communications chief D.J. Koh, said at the conclusion of the event announcing their findings.
The number of affected phones nears 2.5million. The company has advised their customers to power down and stop use of their affected device immediately.
