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

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 to speed up the charging at a rate that the battery couldn't handle...

It's time to cover something new. This site has become SamsungArena.

Dude they're holding in the urge to come at this point, I mean it's so obvious how much good the Note 7 cancellation is for PA's "news quota". I mean that one article about losing faith in Samsung read like a high school freshman's Casanova.

Actually, is there a reason they can't solve this the old classic XDA way and just underclock the device? The Note 7's combustions are not limited to when they are charging, so in general, the device just has a tendency to heat up and just catch fire. So wouldn't the easy way to fix this would be to underclock the device? Less voltage to the motherboard, less heat on the motherboard, less heat on the battery, keeping the entire phone slightly cooler and less prone to combustion? Now, if all the Note 7s that caught fire did when they were charging, that would be something else, but as of right now, even ones that weren't charging have caught fire.

Exactly. Which si what makes this theory, BS. It's not Samsung's theory. But here s the issue. With the one that exploded when the guy got on the plane. He claimed he had just finish charign the phone wirelessly. Not. The phone was no longer on the charger. So what chain reaction is being causes, that after he charged it, the phone continued to get hot until it caught fire? The issue I see is. When you take a phone off the charger, its already hot from charging. Why would you smother it by shoving it into your pocket? Seems you would let it cool from charging. In my experience, every Galaxy Note and S I've owned, got fairly warm while charging, especially if you charge while using it with the display on at a higher brightness than 30%. I've taken them off the charger and placed them in my back pocket and I can feel the heat. So I take it out until it cools. This is equally as dumb as a fool who would charge a phone and have it under a pillow. The display could turn on adding more heat. The heat is trapped on combustible material, which gets as hot as the source heating it up. With all that heat trapped, it is obvious the phone will catch fire. I do not understand with the billions of dollars that all these company's make every year, why someone has not found a safer power source for mobile device, other than Lithium-Ion. There has to be something better.

OK, first you guys said it was the design and now it may be because they tweaked the soc. What's next? The screen resolution I too high and the battery can't handle it?

But it wasn't Samsung though that is making the claim. They are just guessing. They need to find out what the issue is because, the S8 and Note 8 are coming, and at this point they can't afford to have a fiasco with the Galaxy S, because that is their true money make. The S sells 3 times the amount of phones as the Note, and right now the S reputation is not tainted with any flaws. In fact the Galaxy brand as a whole is virtually flawless, until the Note 7 issue.

All these writers and haters really need to get a grip. Samsung Electronics makes 100's of products. They make 50+ models of phones. They make appliances. They make components. At least 95% of their stuff works with no issue. No company on this planet has ever made a product that didn't even have a problem. NONE OF THEM. Intel purposely sells defective products on the market ever single day. It's called the Intel Celeron. It is a Pentium CPU, that has defects in workmanship, but the chip is not completely unusable. The defective parts of the chip are disable and sold at a cheaper cost. Every single car manufacturer, whether foreign or domestic, has had recalls on cars. In fact some models have had multiple recalls. Toyota, as much issue as the Camry and Prius has had, it is still being sold under its original badge. Even luxury brands like Mercedes. When Chrysler was part of Mercedes, they all like GM bought Airbags from the same supplier. Those Airbags have been found top be faulty. Mercedes has used those bags in nearly 1M cars. The defect can cause the bag not not only explode, but cause the material inside to expose to the driver and cause serious health risk or even death. Do you think people are going to stop buying cars from Benz? Every single car brand sold in the USA and over the world have had recalled. Ford and GM are on record for doing a recall on cars nearly every year. The Galaxy Note is not a flagship device. It is a premium model which has the second most sales. The Galaxy S is the flagship model. I am not saying, people won't have second thoughts about buying a Samsung phone or whatever. But it is this simple logic people seem to be to stupid to understand. People do not care if a product shows a sign of defect, even if said defect causes an injury. What they do care about is, if and when it happens, the manufacturer of the product will stand behind that product and do whatever it takes and even spends what is needed to solve the problem. The fact is, Samsung never has to even find out what happened with the Note 7. But it would help to insure the issue doesn't happen again. The fault could literally be anything. At this point, they will save money by not selling the devices to people, having millions of people risk injury. Many of the parts they have already secured and used, will simply be used in other device, so it won't be a total lose. The fact is, their only lost will be from not gaining the extra sales from an extra model. Samsung has the money and the brand recognition to move forward. For the writers and fanboy idiots who can't move forward and make needless stupid articles and lame jokes on the matter, will have their day of Karma! The Note sales drop, means Samsung will lose money. Once lost it really can't be totally made up. But the lose is a complete write-off.

I race rc cars and I blast my lipo battery 3900mah at 70 amps and it's done in like 4 mins.. battery don't last and swells after a while.. my note 4 battery lasted about a year and a half with fast charging. Fast charging is nice but battery will take a hit specially when it's in closed inside a phone like that all tight sealed and when something goes wrong the baterry swells and poof.. seen it so many times at the rc track and lipo packs stink

Genuine question, note 7 had both eynox and snapdragon versions yes? And generally US is the one's that get snapdragon, is this problem only with snapdragon phones? because that could seem to indicate potential problems with all snapdragon phones with the new charging tech in them?

Why are they using a picture of an S7 Edge for this story?

The first thing I did on both S7E and N7 was turn off Fast Cable Charging under settings. It only shaved a few minutes of "adaptable fast charging" which they have had since Note4, and created a ridiculous amount of heat. Same with fast wireless charging. I tried a 3rd party wireless charger on S7 Edge and it continued to cook the battery for 6 hours after reaching 100% capacity, sure. Speed? Not at the expense of safety and battery longevity. Heat is the #1 way to shorten Li-ion lifespan.
