samsung note 7 exploding.. WHY???

Post by pratik001 » Thu Jan 26, 2017 11:09 am

Samsung launched the Galaxy Note 7 to record preorders and sales in August, but the rosy start soon turned sour. Samsung had to initiate a recall in September of the first version of the Note 7 due to faulty batteries that overheated and exploded. By October it had to recall over 2 million devices and discontinue the product. It's estimated that the recall will cost Samsung $5.3 billion.

it succeeded in recalling 96% of the totall sold. and built a new test lab. It staffed it with 700 researchers, 200,000 devices and 30,000 batteries in an attempt to replicate the cause of fires in the phones. It tested the whole device, including areas such as the role of wired and wireless charging as well as fast and normal charging. It also tested the water resistance, with and without the back cover.

Samsung tested other device features such as the USB-C charger and Iris scanner. It evaluated the software and algorithms tied to wireless charging. It even evaluated how third party applications were impacting the phone. Additionally, it worked with three independent third party test labs - UL, Exponent, and TUVRheinland - to assess issues across software, hardware, manufacturing, logistics and handling. The finding from Samsung tests and the independent labs revealed the same results.

Battery manufacturing issues led to smoking phones

What happened? In short, batteries from two different manufacturers had flaws. The principal root cause of the first manufacturer’s battery problem (Battery A) was negative electrode deflections. The second manufacturer's product (Battery B), suffered from abnormal ultrasonic welding burrs. (For more information on the flaws see the infographic ) While the principal cause was different in each type of the battery, the result was the same. A small subset of batteries could overheat and potentially catch fire. It’s clear that the smartphone industry’s desire for ever thinner phones with longer battery life has strained battery manufacturing processes.
