Here's why your Galaxy Note 8 won't explode

Samsung has done several things to ensure that what happened last year won't happen again

We popped to see the Galaxy Note 8 last week. Aside from a brief mention of an 8-Point battery check, there was no talk of the Samsung Galaxy Note 7 debacle in the briefing that preceded our hands-on time. 

That was in stark contrast to the tone of Samsung's Mobile World Congress keynote in February, where we heard the company talk about "one of the most challenging periods in our history". 

But what has Samsung actually done to ensure there are no Note 8 battery problems? The answer is pretty simple. 

What is the 8-Point battery check? 

As we said, the Galaxy Note 8 battery has undergone Samsung’s 8-Point Battery Safety Check, which it claims is the most rigorous in the industry. 

This involves enhanced processes for several existing areas, including more stringent durability tests, visual inspection, x-ray tests and any voltage abnormalities. 

Crucially, there are also several new tests. A charge/discharge test now happens for every battery. 

An accelerated usage test means each battery undergoes intensive real-world scenario testing. 

Finally, another test called TVOC involves the detection of volatile organic compounds, essentially ensuring there isn't any leakage of the battery components. 

There's also a conservatively-sized battery

The tech giant has also erred on the side of caution, included a relatively small 3,300mAh battery in the device, in contrast with the 3,500mAh battery inside the Galaxy S8 and the S8+ - that was also the size of last year's Note 7.

Mind you, it's still significantly bigger than the 2,900mAh unit in the iPhone 7 Plus.

It's enlisted outside help

Samsung contracted an external firm - UL International - to work with it on battery tests. "We have been closely working with Samsung... in the science of smartphone quality and safety evaluation. As a result, the Galaxy Note 8 has successfully completed a rigorous series of device and battery safety compatibility test protocols.” said Sajeev Jesudas, head of UL International. 

What happened with the Note 7

A presentation in late January 2017 revealed the results of Samsung's investigation into the Note 7 battery problems. You can watch this on video below or read more about the Note 7 battery issues in our story from January

Samsung had been unlucky because there were two different flaws were responsible for the Note 7 catching fire, rather than any error with the phone itself, with a design flaw in the upper right corner of the original battery leading to a short circuit, and a welding defect on the replacement battery leading directly to overheating. 

In addition, Samsung confirmed that certain units of the second, replacement battery were missing insulation tape.

The battery investigation took 700 dedicated staff and involved contracting UL, in addition to two other firms: Exponent and TUV Rheinland.
