We’ve travelled the journey surrounding the Galaxy Note 7, a Smartphone which was annoyingly good considering the end result, and whilst we recently shared a snippet of what was known about the battery problems, the full report by Samsung is now available to show it all.
Samsung have also publicly made available this short 2 minute video to assure customers of the steps they’re taking to assure this never happens again.

What happened + Steps to prevent future incidents
Samsung have announced they’ll be implemented with current effect, an 8 point safety check on all Smartphones, essentially dedicated to prevention of all battery related problems based on the problems experience in the Note 7, as well as further reassurances for customers and shareholders.
The problem with the batteries, which were built by Samsung, was due to a defect affecting the cell grouping. However, the situation of said defects were different on two separate occasions of Note 7 installations. In Samsung’s investigation, they referred to these batteries as simply Battery A, and Battery B.
In the above case of Battery A, the issue was a defect affecting the top right of the lithium ion battery grouping, which in some cells caused fire through repeated successions of charge and discharge on a quick and rapid formation. With such continuous sparks of electricity charging and discharging at a rapid rate, it’s little surprise that just sparks wouldn’t cause fire and naturally the issues faced by the original shipped Note 7.
But those weren’t the only batteries used by Samsung. In replacement units, as well as Chinese variants, Samsung used batteries from Amperex, a Hong Kong facility. However, these also experienced similar defects as the original Samsung ones (or Battery A), however this time it affected the top left portion of the cells.
Where the problem differs is that with this Battery B, the issue wasn’t continuous charge and discharge, it was an issue with short circuits in a small number of units. The Samsung report also found that these Batteries were not equipped with the necessary insulation to protect against any form over overheating caused by the spreading caused by the short circuit issues.
Throughout the investigation, which it’s important to mention was Independent, aided by multiple organisations such as UL, Exponent, TUV Rheinland and more, Samsung now has full understanding of what caused the problem as well as ways to notice the problem first hand, which has led to the company devising an 8 step battery safety check, which will now be done before ANY future Samsung device even hits production, something Samsung was very keen to stress, likely to ease potential Galaxy S8 customers.
So, what’s your take on the Note 7 story, will you get a Samsung phone again? Whilst we think you’ll be fine now, just shows how you can never be too sure!
