Samsung reportedly discovers that faulty battery caused Note 7 fires

By , Jan 16, 2017

Official investigation conducted by Samsung Electronics has determined that a faulty battery was the main reason for Note 7 fires, a fiasco which led to a worldwide recall of the handset before the device was fully discontinued, Reuters reported Monday. A person familiar with the matter told the news gathering organization that Samsung should officially announce the results of the investigation next Monday, January 23, a day before the company is scheduled to reveal its fourth-quarter earnings.

An unnamed source told the publication that Samsung during the investigation successfully isolated and replicated the problem, saying the cause for the fires could not be explained by hardware or software design.

As part of the announcement, Samsung is also expected to share measures it is taking to prevent similar problems in future devices. Some analysts are not convinced that faulty batteries were causing Note 7 fires because the problem persisted on replacement devices that used batteries from a different supplier.

“To me it’d be surprising if they said it was a supplier issue,” said Bryan Ma, Singapore-based analyst for research firm IDC. Many people suspect Samsung may not have given enough room for the battery inside the phone, causing it to catch fire.

As part of its probe, Samsung hired third-party firms to examine the device. The whole fiasco has dealt a 6.1 trillion won ($5.2 billion) blow to Samsung’s operating profit over three quarters. Now the firm is pressured to provide a convincing explanation about what went wrong with the Note 7 as it gears up to launch Galaxy S8 later this year.

    I could have sworn we knew about this before the discontinuation of the Note 7.. Like even. few weeks after the first incident?

  • DogNinja

    The big lie is coming…or not…

  • BlackPantherK

    Well still not buying a samsung device after that whole fiasco

    • Y2J: Keeper of the List

      I wouldn’t have bought one before, definitely not buying one now

      • Amac25

        Agreed

      • jOn Garrett

        35 phones out of 2.5m Samsung recalled them all.

        Touch disease and dead batteries, apple blames the user and charges money to fix it.

      • Rowan09

        Dude stop. Samsung recalled them because it was obvious the problem affected every device. I don’t know anyone with the “Touch disease” and Apple is replacing those device the last time I checked. Everything has issue but don’t try to compare something that’s a hazard to life to a defect. Smh

      • Rob Benton

        Touch disease is bad. I work at a phone shop and we see multiple phones a month with it. Apple charges $129 to “fix” this defect that should be free of charge.

      • Rowan09

        I’ve never seen it what phones does it affect?

      • Michelle

        Pay more attention then instead of worshipping apple 24/7.

      • Rowan09

        Huh? I own a Note 2, Fire TV/TV Stick and S7 Edge as well. Smh don’t make ASSumtions.

      • Michelle

        Pay more attention to apple news. You seem to ignore the negatives.

      • Rowan09

        I pay attention to what affects me or phones I fix. I’ve heard about the issue, but never looked into it since I’ve never dealt with it. What phone do you use?

      • Michelle

        Currently a regular iPhone 7 and honor 8

      • Y2J: Keeper of the List

        Yeah I don’t really care, I hate their software enough as it is, and if there’s a pretty decent chance the phone could blow up (decent enough to not be able to take it on a plane) then that’s all the more reason not to. And don’t take that as an Apple fanboy comment or whatever, I actually like Android (and Windows phones) but despise Samsung.

      • Docservlet

        There were millions of phones ready to catch fire. Samsung discovered a “FAULT”.

        Touch disease comes from excessive flexing. After over 2 years, my 6 still has no problem. On top of that, the PHONE IS NOT CATCHING FIRE you imbecile.

      • Luis Torres

        Sounds like this is turning into a iPhone vs Samsung fanatic battle.. I forgive Samsung for their devices catching on fire, they responded quickly which, they offered full refunds or the option to switch to the s7 Edge (still the best phone out there right now) with a bunch of other bonuses ; this incident also brought awareness to other manufacturers such as LG who is implementing heat sinks on their devices. Samsung smartphones are still the best in nearly every aspect, their reputation is far from done. It’s actually a good thing this happened as it will improve QC all around. Iphones on the other hand is reliable, nothing special about them really, they lack innovation, but good enough for simple use.

      • BasedOnAir

        When’s the last time a major airline installed bags designed to contain potentially explosive chemical fires and later banning the device from all airplanes over a broken touch screen?

    • jOn Garrett

      iPhones burst into flames, spontaneously bend, have touch disease and batteries that die for no reason yet you have no problem with that?

      • Blip dude

        Uhh, I do. Especially when I get a fucking replacement device that actually turned out to have even bigger issues down the line. It was a coincidence that the phone had NFC and Bluetooth within 3-5 days after the warranty’s expiration and now they are charging me $329 to replace this one with yet another possible refurbished one.

      • Docservlet

        This is pathetic. There is no equivalency here. As hard as you try, there were Note 7s exploding all over the world and you can’t deny it.

      • Luis Torres

        -Look, we get it. You’re a Samsung fan boy.

        I forgive Samsung for their devices catching on fire
        -I’m sure you do. The problem was releasing that turd in the first place. It was a massive QA problem and Samsung shouldn’t be trusted.

        switch to the s7 Edge (still the best phone out there right now)
        -The S7 Edge is far from the best phone out there. The iPhone 7 is the best all around phone on the market with the most impressive ecosystem.

        they handled it very well
        -They handled it horribly. They tried to bribe people to prevent them from posting pictures of their exploding Note 7s.

        Samsung smartphones are still the best in nearly every aspect
        -Samsung smartphones stink. They run a forked and non standard version of android. Their skinning has slowed down generations of galaxy devices. Both touchwiz and Grace show massive issues with lag, wifi problems, bloatware, charging and errant inputs inputs on the sides of the edge display.

      • Luis Torres

        Yes I’m a Samsung fan, all the high end PCs I’ve built have Samsung Vnand SSD, even my GPUs use their IC chips, my phone is an LG though (anything but IOS) Lol

        Just incase you didn’t know your impressive Apple used Samsung parts in their phones previously, until Iphone 7, now they have their powerful A10 processor along with TSMC chips.

        Samsung makes some of the best IC chips and screens which is why manufacturers adopt them, it’s a fact, there is no argument there.. I’ve used both the iPhone 7 and S7, can’t compare as they both have similar hardware, except that Samsung uses a better panel; iPhone screens are manufactured by LG which are not bad, however, they use an IPS lcd which is not as rich as Samsung’s OLED technology.. The next generation Apple products are to possibly use OLED panels manufactured by Sharp.

        Software wise I dislike IOS and MacOS, Samsung’s UI is definitely not the best, I usually install customized software on my phone’s either way, just because I believe in having root access on a device I own, and altering the phone to my liking.

        All these posts are subjective sir which is okay since everyone one is entitled to an opinion with no facts to back it up. The internet is full of propaganda..

      • Docservlet

        “my phone is an LG though (anything but IOS) Lol”
        LOL!! Another delusional fandroid that got lost somewhere on the internet. I use anything but Android junk.

        “Just incase you didn’t know your impressive Apple used Samsung parts in their phones previously, ”
        Oh really? My car uses Bridgestone tires. Manufacturers get parts from MANY SUPPLIERS. That’s how manufacturing works.

        “Samsung makes some of the best IC chips and screens which is why manufacturers adopt them”
        There are many IC manufacturers and screen manufacturers. In this case, Apple uses CPUs made. by TSMC, Intel and many other suppliers. That’s how a supply chain works.

        “Samsung uses a better panel”
        Samsung uses a newer panel. IPS LCD still has many advantages over OLED. White levels on LCD are better and the iPhone 7 display leads all devices in many key benchmarks. OLED is newer but has it’s fair share of difficulties like dead pixels, burn in, and yellowing. Possibly Apple will use OLED. Hopefully with improved white levels.

        “Software wise I dislike IOS and MacOS”
        As a samsung fanboy, I figured as much.

        “All these posts are subjective sir which is okay since everyone one is entitled to an opinion with no facts to back it up.”
        Perhaps it’s best to steer your mouse back to android police. I have no sympathy for Samsung or it’s CEO.

      • Luis Torres

        It’s all good man, don’t hold back lol I discuss tech for fun.. I go at it with the Mac fans all the time, and not once do I say anything bad about Apple ..

        I’m not really a Samsung fanatic, Im more of a tech enthusiast, I like building PCs for fun, jailbreaking/rooting phone’s for fun, currently in school for software development, I discuss in forums to keep my mind sharp in the field of tech.

        Anyhow, Samsung does not suck, neither does Apple, I just don’t like their UI, or the phone desing, Android is my preference and so is Windows (no offence Apple). But even tech savvy enthusiasts who are Apple fanatics, who say Android sucks, can acknowledge that Samsung makes some of the best components out there.

        Saying that Samsung sucks should be an offense to Apple since they at each other backs competing for the market, they are at a race for first and second.. It would be sad if they were struggling to compete against a company that “sucks” for no evident reason.. (shame on samsung, for releasing the Note C4 instead of Note 7)

        Samsung does offer alot of cheaper low end stuff for those on a lower budget, but if you put high end hardware from iPhone and Samsung up side by side, it’s the nearly the same exact thing in an unbiased stand point.

        I respect Samsung because the company is innovative and engineers a bit of everything, they make their own microprocessors (Exynos) IC chips which are known for their tight timings, their NVME storage which is amongst the fastest, they are on top of the market in many categories. I can easily ignore the home appliances though, .. oh, and their TVs are just freaking amazing lol

      • Docservlet

        Ok…I’ll agree with this well constructed and tempered response.

        It’s not that I hate Samsung. I disapprove attempts to say that Samsung, Google or Android are somehow better than Apple’s offerings. It’s easy to note that Apple makes their own software and hardware. Apple’s own chipset designs for the A series mobile CPUs, NVMe storage chips, and M9 motion coprocessors for the iPhone and iPad simply lead mobile competitors in terms of performance.

        Apple’s ecosystem and device integration across their entire lineup are simply unparalleled. Yes, it is a walled garden but it is a very well kept walled garden.

      • Luis Torres

        I actually like Steve Job’s aggressiveness and vision which drove the company to having complete control of its own technology design, synergizing a complete proprietary package that defined total perfectionism, Apple still, somewhat, caries his philosophy to this day, the company has become more permissive in certain aspects of design and management, and less agressive towards the competition, yet they hold their place due to their established foundation. (Every company should have a Steve)
        The A10 is definitely a two core power house which puts the snap dragon 820 to shame (Note 7 rocked this chip which was a let down) as far as raw power goes, im sure Apple implemented a smart design on the kernel for multitask management to compensate for the lack of cores, fast charging, and smaller battery; less power consumption was definitely their focus.

        Samsung’s Exynos which is Samsung’s own design and also manufactured using their own finFET 14 NM process, same as the one TSMC manufactured for Apple, the A10, are up to par in performance, the A10 most likely performs better in gaming.

        But now we have Samsung and TSMC competing with the new finFET 10nm process, and how small this microarchitecture is, its just simply amazing.. once again Samsung and Qualcomm colaborated, this time to bring the latest 10nm Snap Dragon 835, Apple is going to have some serious competition there, for alot of the upcoming android flagship devices will most likely utilize it.

        “No more galaxy C4s Samsung, please! Otherwise Life’s Good”

      • Michelle

        That’s funny considering they were only released in the u.s and Canada at the time.

      • BlackPantherK

        I know iPhones have had problems in the past (and further), but these problems are less of a DANGER than what Samsungs devices where doing. I’m a frequent flyer and the last thing you would want to see is a phone bursting up in flames next to you or on you. People got hurt because of those things, does a touch disease, batteries that die or the bend gate hurt anyone? Well no, but it does not mean that it doesn’t bother me at all…. Because it does.

        All said, if Samsung comes out with a beast of a phone without bursting into flames I might reconsider of switching, but until now I will stick to Apple.

    • Luis Torres

      Yeah that’s what everyone says.. lol but they will most likely emerge to the top again even after that fiasco, because they simply make the best products. Samsung makes some of the best hardware out there, especially the IC chips which many other companies adopted for their products, including Apple. Even if you don’t buy a Samsung device you might still have some Samsung in your device lol

  • GUY

    What a shame

    • ic0dex

      same here. I skipped the iPhone 7 to try the Note 7 and it was one of the best phones I have ever used. I never enjoyed a phone the way I did the note 7. With this iPhone I’ve been looking at the same icons and apps for the past 9 years. I hate waiting for a stupid jailbreak.

      • Rowan09

        I never owned the Note 7 but what did they do to make it so much better than the S7 Edge which I own? (Please don’t mention anything with the S Pen because I own a Note 2 as well and never used that thing)

      • Bugs Bunnay

        the note 7 had the updated s pen. wahahaha

      • Rowan09
      • Luis Torres

        That’s a good point, there was not much of a difference between the two, but the note 7 is by far the best I’ve owned :-/ ..

        “the S pen was liquid smooth though.. like writing on paper with a ball point pen..” (salivating)

      • Rowan09

        Oh

  • Jamessmooth

    I’ve bought a few Samsung products over the years and I’ll never buy another one again. Had nothin but issues with them. I also agree with the analyst; I have a hard time believing it was the battery when they switched suppliers midway.

  • ic0dex

    We all knew it was the battery. These same batteries are in the iPhone 6 and the 6S. The difference, lower power consumption, mhA and no fast charging. The iPhone 6S battery replacement program should be available to both models because they’re all defective.

    Started with iPhone 2G, iPhone 3G, iPhone 3GS, iPhone 4, iPhone 4S, iPhone 5, iPhone 5S, iPhone 6, iPhone 6S, Samsung Note 7 and gave that up for a iPhone 7. Hands down the Note 7 was one of the best phones I have ever used. its a shame what happen to that device.

    • Rowan09

      It wasn’t the battery. They made the same assumption before they sent out the new batch and it still didn’t fix the issue. Point is they have no idea and just trying to blame it on something, they already said before.

  • Rowan09

    They still have no idea after all this time. You can’t blame the battery when they switched companies and had the same issue. They better hope nothing like this happens with the S8.

    • Bugs Bunnay

      i’m sure if someone with the note 7 do a little wire work with another battery source, matching dc value of course, then further testing could be made. I don’t think the average person will know any of this though. i’m really tempted to buy one and try it out myself. obviously try it out on a fireproof work station and extinguishers on site.

      • Rowan09

        Lol. You can’t buy them unless someone kept it you know. You can’t even post them on any website for sale. Plus I believe Samsung sent out an update to make them useless now. I know they sent out an update to stop it from charging pass a certain point. For those who didn’t send them in yet.

      • Pilot

        the fact that 4% of users haven’t returned their note 7’s indicate they would rather risk thier phone blowing up during a phone call or in their hands or pocket and harming people around them then just get the stupid refund for a different phone.

      • Rowan09

        Some people are just dumb, no phone/device is worth it.

  • Luis Torres

    Can’t wait for the S9!

    • Docservlet

      Another in a long line of mediocre phones and “me too” attempts.

      • Luis Torres

        That’s the how the market in general operates, except Samsung is better at it..

      • Docservlet

        Samsung isn’t very good at it at all. They’ve successfully built a business on a copying iPhone but really their business is mostly at the low end. Their ASP is around 250 bucks which means mostly they sell junk.

      • Pilot

        Samsung actually has a list on how to copy the iPhone

  • JulianZH

    Still waiting our refund on the washer.
