Picture this: You got yourself the new Samsung Galaxy Note 7. Been using it for a couple of days and the experience is breath taking. One day, you leave it to charge and step out of the room. Then your hear BOOM!! You run back to see your phone blown to pieces (see picture below).
This has been the drama for some users of the new Galaxy Note 7. Over 40 cases has been reported globally. Samsung is recalling the device, and giving users new ones (or a different phone till it is replaced). Now to the big question
Why is this happening?
Here’s an official statement from Samsung:
“Based on our investigation, we learned that there was an issue with the battery cell. An overheating of the battery cell occurred when the anode-to-cathode came into contact which is a very rare manufacturing process error. We are working with multiple suppliers to ensure that a rigorous inspection process is conducted to ensure the quality of our replacement units and we do not anticipate any further battery issues.”
You see, the Lithium material used in making most phone batteries is highly reactive, and susceptible to thermal runway. When a faulty battery overheats, the cells open up, resulting in a chain reaction of other cells breaking. This is what causes batteries to explode in many cases – a simple short circuit or a design flaw could trigger this.
The recalling process could cost Samsung as much as US$1 billion. We hope Samsung recovers from this malady caused by a “very rare manufacturing process error”.
