A teardown of the Galaxy Note 7 may have provided insight into why the infamous smartphone was prone to explosions, causing Samsung to recall and eventually cancel the device entirely. While it’s obvious the battery was a key reason for the device’s failure, a damning new report from a third-party shows what may be the underlying cause.
After acquiring a Galaxy Note 7 — no easy feat once the phones were recalled — engineers with manufacturing technology company Instrumental stripped the phone down to see what was going on inside (and yes, they had a fire extinguisher nearby, just in case). They discovered the battery was so tightly packed inside the Galaxy Note 7’s body that any pressure from battery expansion, or stress on the body itself, may squeeze together layers inside the battery that are never supposed to touch — with explosive results.

Batteries swell up under normal use, and we place stress on a phone’s body by putting it our pocket and sitting down, or if it’s dropped. Tolerances for battery expansion are built into a smartphone during design, and Instrumental notes Samsung used “a super-aggressive manufacturing process to maximize capacity.” In other words, the Galaxy Note 7 was designed to be as thin and sleek as possible, while containing the maximum battery capacity for long use, thereby better competing against rival devices such as the iPhone 7 Plus and improving on previous Note models.
The report speculates that any pressure placed on the battery in its confined space may have squeezed together positive and negative layers inside the cell itself, which were thinner than usual in the Note 7’s battery already, causing them to touch, heat up, and eventually in some cases, catch fire. Delving deeper into the design, the engineers say the space above a battery inside a device needs a “ceiling” that equates to approximately 10 percent of the overall thickness. The Galaxy Note 7 should have had a 0.5mm ceiling; it had none.
“It breaks such a basic rule, it must have been intentional,” says the Instrumental team, adding, “they shipped a dangerous product.”
The Galaxy Note 7 fiasco may cost Samsung more than $20 billion, and reports of this nature won’t help re-establish trust in the brand. However, it’s worth repeating this isn’t a Samsung report, so none of the findings are official, and that Instrumental itself produces software and equipment for quality testing in manufacturing. This means that although it has a strong understand of what it’s looking at, it is also promoting its own products and solutions in this market.
Samsung’s next major smartphone release is expected to be the Galaxy S8, due sometime in early 2017, according to rumors.
Oh, my GOD you are just over the top. FOUR TIMES in the same thread! Good grief, arl295. Don't you think the one time was enough????
The Breitbart article merely echoed the Australian TV report and covered nothing new.
Of course I read it. I read it when I originally posted it on FreeRepublic back when the event happened. . . both events when you count the burned shipped iPhone 7. I even read the part where they guy stated "My car was full of smoke." It did not burn out his car. The iPhone 7 in question was still wrapped inside his jeans (not I read a lot more articles on the incident than did you, because the fact they were JEANS was not mentioned in that article YOU posted but was detailed in other articles). I also read the investigators' reports about the charger they found in his car, which was NOT an Apple car charger. Apple does not make one in the form they found in his car.
You are the one who seems to be lacking in reading comprehension as you seem to conflate a SINGLE, overheated iPhone 7, which caught fire while charging in a car in the hot sun, where the investigators found the ambient temperatures due to greenhouse effect reached a minimum 140º BEFORE the iPhone caught fire, exceeding the operational parameters of the device, into a device wide failure that is threatening all iPhone 7 models everywhere to the same level as the Samsung Galaxy Note 7 where they had over 250 known spontaneous incident's of fire and explosions worldwide in less than a month!
YOU are the one who did not read and understand what you read.
I quote ONCE AGAIN from Fortune Magazine's article reporting the Australia incident upon which you are so delusionally fixated:
"And at least so far, there haven’t been widespread claims that the iPhone 7, which reached store shelves last month, is overheating and catching fire."
Take your time, read it slowly so you understand it this time.
WOW! You are obsessive and compulsive. FIVE TIMES IN THE SAME THREAD!
No, asshat, SINCE that article? Can't you read? Since the Australia incident. SINCE. That means AFTERWARDS. Find MORE iPhone 7 devices that have caught fire. . . after October 21st. Not the SAME DAMN ARTICLE you idiot. You just proved you have serious reading comprehension problem.
Clearly not, as he's actually up to FIVE now.
Don't bother with him any further, as he's probably drunk. He did put on an epic "stuck on stupid" display, I'll say that for him.
G'night, tomorrow's another day.
Funny. . . but my pager I had way-back-when ran off of a single AA cell. LOL!
Back in the mid 2000s the Lithium Ion battery failure rate was one in 6 million to 8 million per year. It improved due to using purer materials and better manufacturing.
True story, 1995.
They would page the bajepus out of me, what have we got done? where are we at?
I was exhausted with it, hell,I am just calling yall back every minute, nothing has been done.
One day the site manager ripped me for not answering a page (I had left the thing on the nightstand one time in mylife and it was that day)
Why did you not respond?
I said “you see that porta potty over there in the desert? I was taking a crap and it slipped off my belt. I aint going after it, are you going after it?”
No leash ever again
You need a life
I have a very good life outside of this forum, and have had a life which has been varied and involved many interesting things which involved me persons who lived under bridges to others who were elected to the Oval Office or were Chief Justice of the US Supreme Court. I kind of doubt you could say the same.
I'm not the one repeatedly posting the same useless link on a thread where what I am posting has nothing worthwhile to offer on the topic posted. . . nor do I invade threads where I have been repeatedly told I am not wanted or appreciated. That, arl295, would be you.
On the contrary, I have been personally requested by over 750 of our fellow Freepers to do what exactly I am doing on FreeRepublic. You even see some of them thanking me publicly in the threads, but of course you ignore them. There are even more who do so privately in Freepmail. You certainly cannot say that. . . but you have appointed yourself to be a rude asshat and that gets you multiple requests to butt out of these threads by other people trying to enjoy their participation in these threads. You, instead, double down on your rudeness, misbehavior, and incivility and insult everyone present who dares to call you on your behavior, refusing to participate in honest debate and not rising to serious challenges such as actually doing anything we request you do, such as actually doing the Google search I suggested in this thread. Instead, you just re-posted your absurd link multiple times to increase everyone irritation with you. Your intent is obvious to sabotage these threads by making them unpalatable to participate in because of your presence.
If anyone needs a life, it is you. We find you pathetic.
Seriously, get a life
Pathetic, isn't it?
True, Scarlet had that right. . . but she, too, was stuck on Stupid.
Please seek help
I fought getting a pager for years. . . and then, when my girls reached teen-age I needed one for emergency purposes. I cherished my alone time in the car while driving, but alas, I had to give it up in case they needed a ride somewhere because their mother was not available. . . then my business required me to be available 24/7 and the pager was more convenient than my having to answer a phone to find out I really did not need to reply to THAT particular client right then. Some were of the assumption that their emergency was necessarily MY emergency, and EVERYTHING to them was an emergency, no matter how trivial or unimportant. I'd rather return their calls at my convenience than theirs.
Now we have our smartphones and voice mail. . . much better to listen to their voice mail to learn if I even ever need to call them back at all! Now I can listen, text them "See you next week, everything is being handled!" and ignore their emergency. The Triage abilities are much more convenient. LOL! AND much more peaceful.
Hey Ari, truce, let's forget all this phone stuff for a minute.
I note on your profile page you're from New Jersey. I was too, many decades ago (raised there, but left in 1974).
So of course I gotta ask, which exit?
See, there's your reading comprehension problem again.
You did not grasp a thing of what I wrote. . . so you double down with you apparently needing, compulsively to have the last word. Sick.
Read. Every. Word. I. Wrote. Then. Read. It. Again. To. Gain. Understanding.
You can do it.
If you feel you must reply, believe me we do understand compulsions, please do it with out resorting to ad hominem attacks or implied insults, especially the insulting slurs using faux concern for my well being. You probably don't realize it, but you are projecting all over the place.
Off your meds again?
ROTFLMAO! Am I right or am I wrong. He clearly is so compulsive he had to have the last word. . . and he just cannot read for comprehension and/or follow instructions. LOL!
Good night my friend.
Morton Thiokol, page your office...
Funny, I didn't even know compact phones *had* O-rings...
And Samsung didn't even have a Utah Senator on the Air and Space Committee to please by giving the contract to a Utah company thousands of miles away from where the solid rocket boosters, er, phone would be launched. . . which didn't even have the lowest bid. . .
Wouldn't it have been a hoot to watch Dick Feynman dunk a Galaxy 7 in a cup of ice water to make his point?
(imagination breaks free, runs across the yard): "...Tonight on Mythbusters; can you use your phone in an emergency to start a campfire?"
