The Port St. Lucie Police Department released this video of a car fire on Sept. 13. The driver told investigators he was charging his Samsung Galaxy Note 7 when it burst into flames. How could this have happened? Simple: your phone is a Samsung Galaxy Note 7 — and it’s one of over a hundred that have spontaneously burst into flames.
After 35 reported incidents of overheating smartphones worldwide, Samsung made the unprecedented decision to recall every single one of the Galaxy Note 7 smartphones sold.That’s said to be 1 million of the 2.5 million that were manufactured. (Since the recall was first announced, the number of explosive Note 7s has nearly quadrupled.)The company says it’s stopped all sales and shipments of the Note 7 and is working with government agencies and cellular carriers around the world to provide refunds and exchanges for the phone.
In every country, the message is the same: return your Samsung Galaxy Note 7 now, just in case something bad might happen to you.
The Note 7 battery fiasco is a huge black eye for Samsung, made worse by the fact that it’s playing out just as the company’s archrival, Apple, is releasing its new iPhone 7 and iPhone 7 Plus.
But how bad is it, really? What causes a phone to explode this way, and why this specific Samsung phone?
Here’s what we know about Samsung’s battery woes.
Why didn’t the phones catch fire immediately?
When Sadoway explains these theories, one thing doesn’t seem to add up. Today’s cell phone batteries generally charge faster (and get hotter) when they’re first plugged into the wall, not at the end when they’re trickle-charging the last few percent to reach their maximum capacity.
But these Note 7 phones didn’t explode right away. In practically every reported instance of a Note 7 catching fire or exploding, it happened after the phone was plugged in and left charging, sometimes overnight.
Then, there’s the little matter of how Samsung plans to make these phones safer — by issuing a firmware update that keeps the Galaxy Note 7 from charging to more than 60 percent of its full capacity. How could that possibly help, if things heat up the moment a phone is plugged into the wall?
Sadoway has a theory — albeit one without proof. What if only part of the battery was squished improperly, so that the phone couldn’t tell when it was 100 percent charged, and kept on charging the cell?
When lithium ion batteries are continually trickle charged, the lithium ions can start to cover the surface of the negative contact in a coating of lithium metal through a process called “plating.” And in extreme conditions, that lithium metal can form tiny spikes (called “dendrites”) that can poke right through the separator, creating — you guessed it — a short circuit.
That would seem to line up with the “variations in tension” Samsung says it found inside the defective battery cells.
“My guess is by backing off to 60 percent charge, they’ll be well below the threshold where these things happen,” says Sadoway. “Imagine we’re trying to fill our gas tank, we don’t have a really good regulator, and we don’t want to spill the gas all over our shoes. We want to make sure we’re cutting off the flow well before this thing gets to overflow conditions.”
Samsung didn’t immediately respond when asked for comment on the theory.
