Samsung may have tweaked the SoC inside Note 7 to speed up charging, but battery couldn't handle it

Even though Samsung thought it had solved the battery issues that led to the first Galaxy Note 7 recall, things seem to be more complicated than the South Korean company originally estimated. Forced to make a second recall of the Galaxy Note 7, Samsung is now trying to replicate the issue that turned its phablet into a “hot” topic since its launch.

For the time being, there's no clear answer from Samsung as to what's causing its Galaxy Note 7 units to explode despite the fact that the handset maker changed the battery supplier for this specific phone.

However, a new report coming from Financial Times presents us with an interesting theory that now puts the blame on Samsung's engineers rather than the supplier the company claimed it provided the faulty batteries inside the Galaxy Note 7.

It looks like someone was told by Samsung executives that the issues with the phone stem from the fact that the company's engineers have tweaked the SoC (system-on-chip) to speed up the charging at a rate that the battery couldn't handle.

Naturally, this is just a theory that hasn't been confirmed by Samsung, but we wouldn't be surprised if the company won't find the real reason behind the Galaxy Note 7 fiasco. Either way, it's important that these things won't happen again since Samsung's credibility is on the line now.

Trust is not something that one can gain overnight, but it's definitely the kind of thing that you can lose in the blink of an eye.

I doubt they'll ever release the real reason why they were defective to the public. But whoever was in charge of designing them will probably be fired.

They will release precise reasons for the problem. If they let it vague suspicion will fall on all other devices (present and future). If they point to specific reasons they can then argue that it will not happen in the future. That promotes assurance. Someone will be fired, yes. That also promotes trust.

"Someone will be fired, yes. That also promotes trust." I hope Trojan_horse doesn't lose his job at samsung. As he failed to defend his boss and the boss is now angry.

Yes. Some of them exploded while they were sitting idle and not getting charged. So this cant be the only reason. There is something more to it.

I'm sure there will be independent research teams determining the cause. It won't be Samsung alone. Every phone maker has a stake in this issue because no one else wants it to happen to them.

I hope that it's true, that will make the solution very easy. But no its a bigger issue. And I would like to know what went wrong.

"we wouldn't be surprised if the company won't find the real reason behind the Galaxy Note 7 fiasco" or maybe they know but they are hiding it from the public and trying really hard to minimize the damage.

No they will have to tell the findings if they find the problem or a lot of people will say , if they did not find the problem then how did they fix it. That is the only way trust will be regained with a lot of people.

Samsung must now scrap their mobile division and should concentrate on their explosive washing machine and electronic tooth brush to make them safe for their users.

I prefer Sony's safe charging than quick charging. I dont mind to wait for another half an hour or one hour extra to charge.

That's how I feel. If you can't be away from your phone that long then you probably need help.

Sony is a high class premium brand with years of experience of building premium products so it's no wonder they brought meaning features unlike a certain korean company which rushed to release phone with gimmicky features with fundamental design flaws. Sony xperia XZ >>>>>>>>>>>>>>Any samesung phones release in this year. (BTW, samsung engineers have no ideas what is causing the note 7 to explode, LOL, so much for a world class company).

I dont agree with you regarding, rushing of Releasing Note 7. they released Note-5 before Iphone 6s. What I feel is, Note 7 doesnt have much space for this much bigger battery and if they reduced the battery capacity little bit or increase the thickness little bit more, it would be fine.

Well, too bad samsung engineers can't figure out what is causing the explosion. Samsung's new mobile chief D.J. Koh was enjoying the fruit of their previous mobile chief J.K. Shin's hard work. Under J.K. Shin's command samsung may not produce good looking phone but they did produce safe product. Note 5 has only 3000mAh ( if i'm not wrong ) but note 7 which has basically same size put 500mAh more battery without proper safety check. It's all comes down to Samsung philosophy - put bigger features, bigger battery and higher/bigger resolution screen without regardling the consequences of the bigger specs. This is way samsung phone lags, explodes and have pretty much mediocre battery life if you consider the battery size. Bigger/higher specs is not always better and Samsung's phones are the prime example of this. But too bad their fanboys always think bigger/higher specs are always better. Shame.

As much as i agree with all you said about Samsung. Apple starting to do the same. Bigger screen but using cheaper material ( screen disease on iPhone 6 and sometime iPhone 6S ) iPhone 7 has a tendency to overheat and its camera lense cover is cheap ass glass thats scratch super easy ( was saphir on older model ) both Samsung and apple need to start doing better quality check and stop trying to screw clients..

Most people prefer spec over quality. Quick charge and bigger battery capacity are the best example. So OEMs nowadays pushing more specs into the phones with no quality checks. People ignores the brands with quality build with less specs. Ex Xperia

You dont know anything. People like you sound dumber than a donkey. the s7 edge battery has more mAH than the note 7 and they arent starting on fire

All in all, the tech was not properly implemented. Poor QA, poor research. That's what they get when they rush production; skipping names, and pushing themselves too hard. All in the name of profit$$$.

25. sissy246

Posts: 7129; Member since: Mar 04, 2015

Agree with the poor QC but not the rush like so many are saying it was only like 3 weeks sooner then the note 5 release date and skipping the name has nothing to do with it. Note 6 or note 7 name doesn't matter .

Your whole point is stupid. They didn't rush the phone. It was only released a month early. The name means nothing, accept what you make it. That's like claiming, just because you are born with blond hair, that you will automatically be stupid or a bimbo. Could it be poor QA? Here is the deal. We've seen videos of how Samsung tests their phones. Based on facts, Samsung does the most thorough and extreme tests on their phones vs ANY OEM. PERIOD. If an issue never showed up during testing, and the products passes, then what else are they suppose to do? It not the same as with the iPhone 4. Steve Jobs finally admitted they saw stuff in testing about the antenna issue. Which is why they made that band which they tried to sell and make money from. You think Apple didn't know the iPhone 6 Plus took less strain to bend? They have bending machine. All phone makers have those. They already knew it would only take 75lbs of pressure to bend them. They just didn't care. They could have used stronger material from the very beginning. In 2 cases right their, Apple was allowed to sell defective products to the public and one of them now is starting to cause injuries to people. Apple didn't even give a carp, which is why they are begin sued. At least Samsung is doing something about it. You act like company's aren't suppose to EVER have an issue. It is impossible for a company to make 100% perfect products. We only ask they be safe enough for use. If they can't be, remove them from the market. Samsung is doing just that. Will Apple follow? 3 iPhone 7 have exploded. Several iPhone 6 Plus have exploded, yet Apple is still selling them. Here is how I see it, if one phone explodes, and the issue is not caused by using a 3rd party charger, where the phone just overheated under normal usage and charging and it blows up, then the fact is, several phones could have the same defect. The sales should be halted until it is fully investigated. No matter the brand.
