This infographic shows what the problem with the Galaxy Note 7 was
Samsung released the full report of its Note 7 investigation on Sunday. But, quite honestly, the results were bloated by a lot of information that very few people actually need to know. Long story short, the batteries were defective, the Samsung Galaxy Note 7 was not. As for what was wrong with the power packs, take a look at the infographic below.

Basically, what caused the issue with the Samsung SDI batteries was deflected negative electrodes, due to the units' rounded corners. This allowed the electrodes to make contact with other internal components, and create a short circuit.

As for the Amperex Technology batteries, there's a different reason. High welding burrs on the positive tab pierced through the insulation tape and separator. And once they did that, they came into contact with the negative electrode, causing a short circuit. Additionally, some Amperex power packs had no insulation tape altogether, which subjected them to a higher risk of short-circuiting.


Long story short, Samsung claims that both battery manufacturers made huge mistakes in the manufacturing process and the infamous phablet itself is not to blame. The possibility for this to happen are probably one in a million, but we've seen more than enough weird coincidences in our lifetime, so we have very little reason to question Samsung's investigation results.

Samboy will reply this because you've hurt their feelings. "AT LEAST SAMSUNG ADDRESS THIS ISSUE, UNLIKE APPLE'S YOU'RE HOLDING IT WRONG EXCUSES" funny to see Samboy meltdown and always use the word 'Apple' as defense shield

Both of you are stupid. I guess you've never bought a product that was defective before? I really don't care they had an issue with "ONE" phone. See that's how sh1t stupid you both are. Samsung makes 50+ models of phones. They had an issue with "ONE". So one phone is suppose to make me not trust them? For an issue they've NEVER had before? Yet some OEM's had with every single model? I don't need to mention any other OEM's. They don't matter. Still rocking my perfectly working Galaxy Note 7 "Blue Coral". There is only one thing that would make me never buy a Samsung product or any one else's product for that matter. When you product ceases to offer the benefits I want or need, is when I won't buy them. As long as they don't kill me, I don't see a reason to not buy them. Bozo?Krustu T Clown must be you guys father. Because you're both stupid and like Bozo/Krusty...NOT FUNNY!

Hope you dont own a huawei or iphone since Samsung make batteries for iphones, and this year the OLED screens on iphones will be samsung made. So never buy an iphone since there is a very high chance something on that phone is a samsung product, it could be the display, RAM, Storage, Battery.

Samsung lies and the logical prove is: When they change to another supply they still have battery issue which is impossible. but the real reason is Samsung ask for more mAh in a small size and the vendor has to deliver and to make short cuts. and every vendor has to give Samsung what they want or otherwise they will lose a good amount of revenue. And Samsung knows about all this.

it's not necessaryly engineers that did this repport, but probably some marketing /brand image expert so this is not necessarily the true reason but something they made so sheep's cans believe. or not.. . the thing is to use your brains and logic to see it this is true and as there where two suppliers I am not entirely convinced by this repport.

Really its impossible that a second manufacturer has the same issues as the original? Samsung flat out said the size of the battery was a part of the issue, when they switched and started using the batteries from the other manufacturer they also said poor QC on the increased production to accounted for an additional factor on top of the size and construction of the battery.

Know they do not have to do short cuts. You are stupid. Samsung gives a spec. If they can't meet it, they shouldn't try. Its that simple. If however they say they can, then they know they have and are expected to provide a proper working product. They didn't cut corners. Either they rushed the batteries, or the machines were not properly calibrated or whatever the reason it really doesn't matter. If you are a vendor, and I call you to do a job for me, and you tell me this is how much the job costs and you say you can do it, and I pay you for this job and you don';t complete this job properly, you are at fault. Even though Smasung wrote off 2.5Billion, both suppliers will have to give that and then some to cover Smasung's loses and they have to give something for the potential sales Samsung lost due to their screw up. Samsung didn't rush them or tell them to cut corners. Samsung took the blame because its their phone and they are suppose to do so. But its not directly their fault. It is the fault of the vendor who produced the goods.

Yeah, but the OWNED the first battery manufacturer. It was Samsung's error in design that squashes the batter's upper right corner resulting in a short circuit. Samsung FAILED in inspecting the safety of even the 2nd manufacturer. It's still Samsung's fault.

You're right! Let's go to the nearest samsung store and tell your s**t straight in their face! Let's make them shameful on what they did, those battery ignorant assholes! I forgot, they're just going to laugh at us. You can alone without me you brave, little keyboard warrior.

Only those that would never be Samsung Customer made an effort to post about their undying hated for the brand. The rest would just buy another S8 or Note 8 and Samsung would post their billions of profit in 2018.

Samsung is a greedy company who just wants to blatantly copy Apple and invade the US smartphone market. They have been doing this for years now and that's why there are so many legal disputes in court about this too. Samsung never thought about the product quality and will not think ever. They simply wants more money and money. Apple on the other hand does not copy anybody, make superior quality devices, come up with fresh ideas such as Siri, Finger print, 3D touch, Dual camera, dual tone flash and fresh designs. I my self use a Galaxy S7 and not driven by any fanboy-ism. The thing is I simply cannot shut up about how much Samsung tries to copy others and sell low quality products to consumers.

You've been preaching that for like what, 1000 comments? Don't you ever get tired of repeating yourself over and over again? Can't we go back to the days where people criticize apple samsung, sony etc. constructively for the technology of products they make and not because of some conspiracy s**t? And fyi: ALL companies are greedy in their own ways. They make products because they want to make money, ALL OF THEM including your beloved apple god. Relax, drink some beer and learn to appreciate your mum dad or whoever you love when they're smiling back at you. Welcome to the real world kid.

Dual camera?? You think Apple started it all of?? Fresh designs?? Right now The galaxy range and even huawei phones have better original desigsn. Fingerprint sensor?? Im sure there was a motorola phone who had it years ago. All apple do is make things popular people buy into they hype behind Apple. Dont tell me next year you will be saying Apple make OLED screens :D Actually do it I need a good laugh.
