Samsung is due to finally announce the results of its investigation into the exploding Galaxy Note7s, but a report by The Wall Street Journal has some information about what the company has discovered. According to the publication’s sources, Samsung has concluded that “irregularly sized” batteries are primarily to blame for the debacle, which resulted in a massive global recall.
The report says that the faulty batteries were made by affiliate Samsung SDI and Hong Kong-based Amperex Technology Ltd., the only two firms to supply Note7 batteries. Both manufacturers produced flawed batteries, the company reportedly found, with the first round of fires caused by Samsung SDI batteries. “The issue with the batteries from Samsung SDI was an irregularly sized battery that didn’t fit properly in the phone, according to the people, who said that the incongruence caused the overheating.
