Battery blamed for Samsung Galaxy Note 7 recall

Samsung Electronics has blamed a minor battery manufacturing flaw for prompting a global recall of its Galaxy Note 7 smartphones and is seeking more time to investigate the cause behind its deepest crisis in years.

The Korean company outlined the preliminary findings in a report to the country’s technology standards agency that has not previously been released.

Initial conclusions indicate an error in production that placed pressure on plates contained within battery cells. That, in turn, brought negative and positive poles into contact, triggering excessive heat.
