Yesterday, Samsung delivered their findings, and the final nail in the coffin of the Note7 saga.  After it’s launch in August last year, followed by a recall in September, a relaunch in October and finally a full recall the very same month; the much hyped handset, it seems, was doomed from the start.

The highly anticipated flagship smartphone suffered a number of documented failures where the handset would explode into flames.  Samsung were quick to recall it, offer a replacement service and get a new batch out to the market.  Yet these too, had similar faults forcing Samsung into an unprecedented worldwide recall of the Note7.  Now we have an explanation as to the cause of these.


Samsung Confirms Batteries to Blame

After several months of investigating and testing Samsung have confirmed that they used 2 different batches of batteries for the Note7.  Both of which had unique failures that lead to the same outcome, the positive and negative electrodes within the battery unit being able to connect.




The testing was completed by Samsung and 3 different independent bodies, all of which came to the conclusion, both makes of batteries were to blame.  They released an infographic to demonstrate the failures.






To accompany the diagrams Samsung also provided a press release which highlighted the actions they have taken from this incident and steps taken to prevent it happening again.


Based on what the company learned from the investigation, Samsung implemented a broad range of internal quality and safety processes to further enhance product safety including additional protocols such as the multi-layer safety measures and 8-Point Battery Safety Check. Samsung also formed a Battery Advisory Group of external advisers, academic and research experts to ensure it maintains a clear and objective perspective on battery safety and innovation. Battery Advisory Group members include:


  • Clare Grey, Ph.D., Professor of Chemistry, University of Cambridge
  • Gerbrand Ceder, Ph.D., Professor of Materials Science and Engineering, UC Berkeley
  • Yi Cui, Ph.D., Professor of Materials Science and Engineering, Stanford University
  • Toru Amazutsumi, Ph.D., CEO, Amaz Techno-consultant


“For the last several months, together with independent industry expert organizations, we conducted thorough investigation to find cause to the Galaxy Note7 incidents.” Koh said, “Today, more than ever, we are committed to earning the trust of our customers through innovation that redefines what is possible in safety, and as a gateway to unlimited possibilities and incredible new experiences.”


For those Samsung fans out there it is not all bad news.  This year we are expecting to see the new S8 and rumours of a new Note have begun to gain pace aswell!
