Samsung explains why the Note 7 went boom
PROMISES IT WON’T HAPPEN WITH FUTURE PHONES.
NUMEROUS EXPLOSIONS, TWO recalls, about US$5 billion and a four-month long investigation later Samsung has finally solved the mystery of the exploding phone battery in its Galaxy Note 7 phablet. At a press conference held in Seoul recently, the South Korean company announced there were two separate battery defects that caused both the original batch of Note 7s and the subsequent replacements to blow up.
The external casing of the batteries in the original batch of Note 7s that went on sale in August 2016 was too small for the handset, causing the batteries to overheat and ignite. Samsung recalled all Galaxy Note 7s and replaced them with handsets that had batteries supplied by another manufacturer — Amperex Technology. Being in a hurry to roll out sufficient batteries for the replacements, the supplier introduced manufacturing flaws which, along with other minor contributing factors like missing insulation and sharp protrusions, saw the second batch crash and burn. Samsung issued another recall in October and has since pulled the plug on the S-Pen toting phablet.
