Samsung Galaxy S8 will not be announced at MWC 2017

Large-scale battery testing of the Note7 being conducted by Samsung and third-party researchers

After all, whatever testing procedures were in place a year ago were not enough to catch the problems that led to the explosions of several Galaxy Note 7 units.

Keeping in view its Galaxy Note 7 debacle and its latest findings, Samsung has chose to implement additional safety protocols and an 8-Point Battery Safety Check routine to ensure battery safety. And now, Samsung has finally revealed what caused the phone units to catch fire. The company also enlisted three independent testing firms, UL, Exponent and TUB Rheinland, to conduct their own investigations.

Specifically "incorrect positioning of the negative electrode tip" in the first batch of batteries and "melted copper on negative electrode" on the replacement batteries led to an internal short circuit which in come cases caused the phone to burst into flames. That forecast pushed Samsung's share price to a record high this month.

Around 700 Samsung engineers carried out tests on 200,000 handsets and 30,000 batteries that were charged and drained over several months. The battery's structural problem and manufacturing problems were the main cause, he said.

To that end, Koh says Samsung plans to implement a broad range of internal processes focused on product safety, building on its existing quality assurance efforts with teams that will now focus on each core component of its devices.

A battery advisory group of external advisers made up of academic and research experts is expected to provide the company a "clear and objective perspective on battery safety and innovation".

DJ Koh, the president of Samsung Electronics' Mobile Communications Business, today apologised to its customers for the debacle. "It sounds so odd that two separate vendors would create smoking phones from different batteries and with different causes", says Geoffrey Cain, who has written a soon-to-be published book about Samsung.

However, the testing approach - especially for batteries - has since been changed, and the tech giant has now come up with an eight-point inspection process that it believes will prevent a Note7-like situation in future.

In the second manufacturer's battery issue, it was all about irregular ultrasonic welding burrs. Most of these batteries were supplied by Samsung's subsidiary Samsung SDI. Hardware-wise, new brackets will be added around the battery, and on the software side of things, Samsung promises to improve the algorithms that regulate the temperature and current while a battery is being charged, and how long it should spend on the charger. Currently, the company is reportedly testing Galaxy S8 prototypes.
