Samsung instituted an eight-point battery check to prevent problems it had with the Note 7. According to a Samsung-commissioned white paper, every single batch of batteries is tested, and an entire batch is thrown out if a single battery fails. The company winds up destroying as much as 3 percent of its own monthly battery shipments during the eight-point procedure. Mind you, that new safety check was already in place when Samsung started selling the Galaxy S8 in April. But for the new Note 8, the company went a step further. The famous safety standard company Underwriters Laboratories (UL) is now independently testing and certifying the Note 8's battery pack as well.
A UL rep tells CNET that batteries "have to endure a barrage of drop tests, crush tests and electrical stress tests before they can pass" and suggests that Samsung's factories will be regularly inspected to make sure their batteries are up to spec, Battery standards like UL's are voluntary; nobody forces a manufacturer to get its batteries certified, Samsung decided its reputation was worth the extra cash and time, That's not all, Samsung is also using a smaller, 3,300mAh battery in the Note 8 this year, compared with the 3,500mAh packs you'll find in the Note 7 and even this year's Galaxy S8 Plus, case for apple iphone 7 plus - deep blue Samsung told CNET it's carving out more space around the battery too, and adding "guardrails" for extra protection..
Note that not every single battery is tested. Statistically speaking, the one in your Note 8 probably didn't go under the microscope, and definitely didn't get crushed or punctured with a nail. But others from the same batch did. Samsung hasn't magically invented fireproof lithium-ion batteries, because there's no such thing. And the company isn't suddenly using a safer chemistry instead. If something goes wrong, they're still flammable. But it's highly unlikely that your Note 8 will explode. On average, only one in 10 million lithium-ion battery cells are likely to go bad, according to battery expert Brian Barnett, as quoted by Chemical & Engineering News.
The Note 7's battery was unusually likely to catch fire, even compared with other big battery fails, To put that into perspective: You're 10 times as likely to be struck by lightning in any given year (1 in 1,042,000) and 1,000 times more likely to die in a car crash (1 in 10,000), Do you plan to give up cars anytime soon?, Besides, Samsung's Note 7 was case for apple iphone 7 plus - deep blue an anomaly the likes of which the battery industry has maybe never seen, with over 100 reported incidents of fire and as many as 1 in 10,000 batteries with defects, if you believe an unnamed Samsung official who spoke to Yonhap News..
Even the giant Nokia battery recall of 2007, reportedly the largest in history, was based on a failure rate of less than one in 350,000, Wired reported at the time. In general, we don't expect our lithium-ion batteries to explode, even if we leave them charging all night long or while we're on vacation. (Don't do that, I'm just making a point.) And with Samsung's additional tests, they should theoretically be safer than ever before. Here's my personal opinion: Regardless of what Samsung does or doesn't say publicly, it can't afford for the Note 8 to catch fire. It'll do everything in its power to keep that from happening, and in the unlikely event one does, it will help the owner in a heartbeat.
