Samsung explains why some Galaxy Note 7 batteries tend to blow up
posted by Cosmin V. / Sep 07, 2016, 7:00 AM
If you happen to own a Galaxy Note 7, then you should stop using it if you know for sure that the battery comes from Samsung SDI. At least, that's what Samsung advises customers that bought the smartphone and are already using it.
The South Korean company announced earlier this month that there have been 35 cases reported globally, which will be investigated in order to identify any possible issues with the batteries.
Since Samsung started the investigation, a few more Galaxy Note 7 units blew up in different parts of the world, which even made FAA consider banning this particular device from flying on US airlines.
We already know that the batteries manufactured by Samsung SDI are to blame, but what exactly went so wrong that Samsung had to issue a massive Galaxy Note 7 recall?
An official statement issued by Samsung says that “based on our investigation, we learned that there was an issue with the battery cell. An overheating of the battery cell occurred when the anode-to-cathode came into contact which is a very rare manufacturing process error.”
Even though customers are asking for better batteries inside their phones, the battery technology hasn't made any breakthroughs yet. That being said, it's worth noting that any Li-ion battery has the potential to blow up because of the chemistry products inside.
For example, Lithium has a high electrochemical potential, which is why it's used as an anode inside high-capacity batteries. However, Lithium is also highly reactive and more susceptible to thermal runaway.
When a faulty battery overheats, it causes the cells to break open, thus resulting in a chain reaction of other cells breaking. This is called thermal runaway and it's usually the main reason some batteries explode. The actual defect that causes a thermal runaway can be a simple short circuit or even a design flaw.
It appears that some batteries inside the Galaxy Note 7 suffer from a “very rare manufacturing process error,” so it makes sense for Samsung to replace them as soon as possible.

Samsung has recalled all of the units and issued a software update that limits active phones batteries to a 60% charge to incite people that haven't returned theirs yet to do so. On top of that, the company is posting apology after apology — a string, which culminated in a full-page remorseful letter to its customers, posted in some magazines yesterday.

Maybe they should ban you. It is his life, he wants to keep his phone, why is that bothering you that much? DJ is keeping his phone as well, should PA ban him as well? And should he also "get a life" because he chose to keep his phone?

Because depending on usage you can put in danger not only your life but the life of others too. E.g. during a flight, charging it in a workshop etc. Or if you manage to set your flat on fire and adjacent flats get damaged too. You should get banned too and all thinkless morons who think that holding on to their dear smartphone is more important that basic safety rules.

I've decided that you don't even own a Note 7 because you can't be so stupid as to still be using it can you? Give me a legit reason why you are still using it and i'll believe that you actually own one, like saying you are still using it because you're a fan boy or that you're just stupid. Don't give me BS like this "I understand the risk, bruh. But can't help it. Lol" because that kind of answer just scream to me that you don't actually own a Note 7 and you are just trolling everyone.

Fans are very proud of how Samsung has handled the situation pretty well. A respectable company is doing its best to make sure that the client's life is secured. Imagine if this was Apple, it would probably deny its fault like "You're charging it wrong!" or maybe ignore the news as always.

How they have handled this. ha. How did you think they were going to handle their phones exploding? Before you crap on about apple, their phones don't explode. Had they not done this, it could have turned into a nightmare for them and the note range. Fandroid fanatics are 1000 times worse than Apple. You guys still cannot openly even acknowledge the problem without mentioning apple. You probably think it's a conspiracy by apple.

" How did you think they were going to handle their phones exploding?" Samsung calls off the shipment and offers the replacement for all the defective devices. Isn't that a more than enough satisfactory solution already? I keep mentioning Apple since most of the trolls here are Apple fanboys and pure Samsung haters. They even created more multiple accounts to troll and mess up the comment section here. What's worth mentioning is that Apple has never admitted its fault, nor it offered a reasonable deal when it comes to its defective products, but all its best is to find a way to make sure the profit margin is through the roof.

you really need to calm down mate. Its just a phone and there's no reason to defend so hard for that, thou you're telling the solid and undeniable truth, fact and reality. But in the end its just a phone
