Samsung: battery plates pressure to blame for the Note 7 recall

Samsung: battery plates pressure to blame for the Note 7 recall
In a document submitted to the Korea Agency for Technology and Standards, Samsung has outlined the potential reason for the thermal runaway that causes some Note 7 batteries to heat up and nearly melt the phone

It has isolated a small, but troublesome manufacturing flaw when the battery cells have been packaged that causes unnecessary pressure on isolation plates inside. 

This allows the negative and positive poles to come together at times, causing a short circuit with the resulting thermal runaway that some Note 7 users know painstakingly well. Here's a good demo and narration of what happens with the Note 7 battery when the anode and cathode get together for one unscheduled meeting.


In any case, this explanation has been submitted as early as September 2 to the government standardization agency there, and Samsung has vowed to take care of it immediately, not that it had any other choice. "Even before we have the final result of the investigation, we plan to establish and carry out the best ways to take care of our customers,” said Samsung in its memo to the agency. “We are currently investigating the battery issue in cooperation with battery manufacturers.” 

Well, that cooperation has seemingly resulted in Samsung putting its own SDI subsidiary on ice and a huge boon in business for ATL, the alternative Note 7 battery maker whose packaging is fine, and the phablets made in China with ATL juicers aren't part of the recall.

impossible to fix. all must be sent back. no different than the takata airbag recall. recall them all. issue new ones and save the inner parts for the 8 series of phones.

I will said this, for the last few days, when I surf PA all I see is this: Samsung explode, Apple Earpods, Samsung explode, Apple watch straps, Samsung explode, Apple iPhone preorder, and seventh and eighth and ninth. Really can't blame Samsung fanboy this time, and I'm afraid I have to side with Hallyu and friends

I agree even if the article is note directly about the note 7 recall they seem to always fit it in there.

6gb ram and 128gb storage with 3800mah (if they're going to increase it) battery for note 7 international version. That's all I'm asking from you samsung in your october relaunch in my country.

So why do you want 6gb of ram? it's not going to make the phone significantly faster.

Check out the op3 performance against note 7 then you will believe!

At the exchange of fast battery drainage....no I think 12-14 apps saved in the background is more than enough. The average Joe won't even go more than 4-5 apps back

Lagwiz will not run smoothly even with 32gb of ram. People never get it, lagwiz is rotten to the core. Samsung either needs brand new skin like the HTC one which works really well or just go vanilla android.

Lagwiz blah blah blah. Samsung lags blah blah blah. You like your vanilla android, I don't have problem with touchwiz on my samsung, fair enough?

I'd take features I use over stripped skins any day of the week. Even if others talk about lag that either isn't there or doesn't bother me in any daily usage.

@Martin_Cooper... lagwiz? Your thoughts are about as ancient as your profile pic.

Bigger ram is not for faster phones, it's for accomodating more background apps so that apps won't always restart. I do heavy loads on my s7 since I also use it for work. Not that 4gb ram is small but more ram would be better. Ram for more background apps, decent processor for faster phone, decent gpu for games. I know what I want.

And also for future proofing as applications and games may utilize more RAM in the future not to mention OS updates (granted they may not support the device for more than 2 years but still).

It'll be at least 2 months after they go back on sale before I get one. I gotta make sure everything is good to go.

I guess different countries, different restart for note 7. You're eyeing on lg v20 too dark?

6 gb of ram and quad core processor want help when coupled with the rogue apps within the search engine company and the heavy tw samsung laysbon top. its proven in geekbench everyday when a iphone 6 ran circles around the Note7. you kids in here need to get off your spec hype regarding phones

8. Barney_stinson

It will help ! At least for advanced features but surely not on a restricted os!! And come let's fight with OP3! 6gb will be felt!!

And why ip7+ have 3gb ram??? It can run like fluid on 2 gb right! But adding more features in ios10 with lock screen notification , there was need for more RAM ! Don't you knew!

Updated my IPad mini 4 actually after IOS 10 performance improved a lot unlike IOS 9 (IPad mini 4 2 gigs of ram ddr3 leave a lone IPhone 7 plus 3 gigs of ram ddr4).

You're the kid here. You always point geekbench and every technical. I had iphone 6s and it sucks very bad when I abuse it at work. I only get few stutter when I combine work and games with my exynos s7 edge. Lick your geekbench numbers all you want, real life performance is where I'm putting my money in.

Then......why would you buy a Samsung phone? Even people within the Android community know they are BY FAR the worst flagships to buy for "performance". HTC, LG, and 1+ are all the better buy strictly when it comes to performance, as they all have much better RAM management. And did you just say the 6s sucked because you "abused" it? Get real dude. All you have to say is "I don't like iPhones!" like a normal Sammy knight, don't lie for no reason. We've all seen the speed tests dude........you're playing yourself.

" We've all seen the speed tests dude" Not if you claim HTC and LG currently perform better than Samsung (more specifically the Exynos) phones. Only the OnePlus does better here, for which you trade (a lot) of battery life. https://www.youtube.com/watch?v=GC8Anr5bHDA

That line was specifically for the iPhone actually, but thanks for the extra info regardless.

"Then......why would you buy a Samsung phone?" And who are you to tell me what I want to do with my money? Same s**t with you, why do you buy iphone when it lags and works poorly in true multitasking? Worst flagship? Never had big problems with my s7 edge, came from xperias and lumias and touchwiz never gave me a headache. Htc and lg have better ram management? You mean lg's bootlooping issues since g3 and htc's battery drains whenever they do an update? I'm not a fanboy I use xperias, sansung, htc and apple products and I criticize them according to how I use them in real life. You're brain dead kiko, you're one of the reasons why techblogs today are so rubbish. Always relying on articles but never used anything than iphone.
