Except they don't "literally" explode. They catch on fire and melt, if you think that fits the definition of explode I have some fireworks that I would like to sell to you.


Explosion: A release of mechanical, chemical, or nuclear energy in a sudden and often violent manner with the generation of high temperature and usually with the release of gases.

This is definitely a description of what happens to the batteries.


I think he's trying to argue that because they deflagrate instead of detonating, it's incorrect to call the process an explosion. That's the only thing I can see that makes sense, at least, incorrect and apparently disingenuous though it is in this context.


Except they don't explode by definition and it is just the persistence by the media plus fear and ignorance that continues this stupidity. This Galaxy Note bullshit needs to die.


The Galaxy Note 7 will be outlived by stupidity and ignorance (not that it doesn't catch fire - you know what I mean)


Maybe you should think, "What would I feel if my father did this while I was screaming at him, throwing objects at him, and hitting him?"


Little kids don't grasp a situation that good. If you don't expect them to have an adult brain, it's a lot easier to deal with them. Your emotions are generated by what you think is true - if you think that the little brat is hitting you just for the lulz, then you will get very angry.


Why do so many of these child psychologists not have children of their own?

Edit: This is hyperbole. I am talking about this particular child psychologist not having children. I understand it doesn't mean he might not have a great understanding of how a child's mind works but it means he has never had the stress of raising a child and knowing how hard it is to keep your cool with them. Especially when they are as energetic as my own children.


This is an incredibly powerful comment, I was just looking to see myself if this psychologist have children of his own and came to the same conclusion that he doesn't. The absolute arrogance to not have children of your own but preach to others how they should raise theirs...

-edit -> and be in your late seventies, having long forgotten what it is to raise kids or see your peers raise their own kids.


> Why do so many of these child psychologists not have children of their own?

They know what they'd be letting themselves in for


Why are so many economists broke?


Change for something that occurred in less than .01% of the devices? It is incredible the kind of irrationality that is brought about by fear. It's the same reason that, here in Australia, there is talk of culling sharks after a single person is attacked.


Would you fly to Seoul from Australia if there was a .01% chance of your plane catching fire? That's assuming just one phone on your flight.

.01% is crazy high.


You just went from "the risk for any given Note 7 to catch fire is 0.01%" to "the risk for any given Note 7 to catch fire in the time it takes to fly from Seoul to Australia is 0.01%". Those are very different numbers.


> Would you fly to Seoul from Australia if there was a .01% chance of your plane catching fire?

Given the sheer magnitude of all the other things that may kill you before you even arrive at the airport, let alone the very act of hurdling through the sky at over 650mph in a thin aluminum tube filled with 36,000 gallons of highly flammable/explosive fuel... a phone catching fire is really not much of a factor when deciding to book a flight.


(devices that did explode + devices that would have exploded in the future) = risk

Over three years what percent of the devices would have had the issue?


Failure rates for rechargeable Li-ion batteries are on the order of one in 10 million cells.

http://cen.acs.org/articles/91/i6/Assessing-Safety-Lithium-I...


"Failure" including everything from fire and explosion to peaceful, boring death.

At a rough guess, the number of cells that fail excitingly are probably a fraction of those that fail overall.


One in a million odds breaks down when you're talking about a population size of billions. A couple hundred cellphones every year catching on fire is still pretty noteworthy.


If that's noteworthy, what does one call a class of product that causes >1.25 million deaths per year? (https://en.m.wikipedia.org/wiki/List_of_countries_by_traffic...)

Definitely worth fixing if it's not too hard/expensive, but probably not worth spending much time worrying about it.


How many cells in a laptop? I would assume 3 at the low end, but it can go much higher and many people have multiple laptops, cellphones etc. So, 20 per person on an aircraft is probably a solid round number.

How many people in an aircraft say ~200. How many aircraft in the air say ~5,000. Now that 10 million is down to 2-3 per however often those 1 in 10 million chance is supposed to stand for.


Replace aircraft with car and continue this conversation.


Cars typically have battery packages that can easily survive a cell failure without anyone noticing.


If your phone battery explodes and starts a fire you have better odds surviving a dive out of your car as opposed to an airplane.


You must have a pretty big phone to take down an airplane. If you are driving the car you are much more likely to loose control and cause deaths then a phone bursting in an airplane causing anything more then nasty burns.


Fires in a luggage compartment may be an issue even if they start small.


How would this resolve any issues?


It would have saved Samsung billions of dollars if they could have just replaced the batteries and not had to buy back 2.5M phones.


Don't be ridiculous. They would still have to recall every device, how else could they do it?

You can't send plain faulty batteries back.

And they still don't know why it happened, They tried 2 different batteries from different manufacturers and it was still exploding.


Er... isn't it obvious? They could mail you the replacement battery?


How did you figure out that the battery is the problem? Samsung has yet to figure out a root cause, so it may be mechanical design, or ...


No, I mean, instead of recalling 2.5m phones, you replace 2.5m batteries. Which you can do. Because they're replaceable.


Samsung tried shipping different batteries in the replacements but those still acted up. It's pretty unlikely replaceable battery which have done much.


Sure, but that doesn't change how much easier, cheaper, and less invasive to customers the replacement can be when you can take the batteries out.


No, it would ultimately have caused more fires with no way to blame them on anyone in particular. If we're going to treat batteries as safety-critical components, then it's counterproductive to encourage end users to replace them with the cheapest ones they can find.

Mobile phones with replaceable batteries aren't coming back, and good riddance.


Wouldn't a better solution be to just make sure dangerous batteries don't get sold? Just regulate them for safety like tons of other dangerous goods already are


After the first recall, when a few of the replacement phones caught fire again, Samsung couldn't even reproduce the issue in a lab. Regulation isn't going to prevent bad things from ever happening. You need a fallback plan.


So your solution is to say "no, only large companies are allowed to pick batteries". Well, the Note 7 seems to show how good an idea that is. Plenty of devices have replaceable batteries without them exploding, and if anything, a replaceable battery would let you say "hey, this battery is getting old, let's replace it" rather then continuing to use a device with an old, possibly failing battery.


Well, the Note 7 seems to show how good an idea that is.

Yes, as a matter of fact, that's exactly what the Note 7 debacle demonstrated. There was a quality problem that could cause fires. There was a single party who could be expected to take responsibility. Finally, there was a coordinated worldwide recall.

Problem solved, system working as intended. Sucks to be Samsung, of course, but the end result will be safer batteries for everyone.

Sorry, that's not going to happen. Get used to disappointment.


Or, the manufacturer of the batteries could recall them.

Also, plenty of phones have replaceable batteries, including new models, so I'll just keep buying them. Means I won't be buying Samsung, but that's just an extra bonus.


Yeah, it's sad. I'm fond of my Galaxy Note 4, and plan to keep it running as long as possible -- yes, the battery is replaceable, so I should be able to get a few years out of it -- but once it dies I won't want to buy another Samsung, and nobody else is making a phablet with a stylus.

Maybe some other manufacturer will see the opportunity Samsung has given them to break into this niche.


Well it would have likely solved the Note 7 recall, and any futures battery recalls. It would also allow a user to remove an unsafe battery so that it's not in use while waiting for a replacement.


I thought the problem with the note 7 was with the power controller, and not the batteries -- didn't phones continue catching fire after the first recall?


There is still no root cause for the Note 7 issue, apparently.


Didn't the phones with replacement batteries also catch fire?


Less than .01% of the phones caught fire. The recall is crazy.


If the Note 7 hadn't been recalled then eventually many more would have probably caught fire. We'll never know what the cumulative failure rate would have been if the devices had been left in the field for years. Eventually people would have been killed.


The fraction of phones that caught on fire was similar to the fraction of hoverboards that caught on fire. Normal products with similar batteries have a much lower failure rate.


.10% within a few weeks of release.

Without a recall, that number keeps on climbing and nobody has any idea where it stops. 1% of phones exploded? 10%?

You obviously can't unexplode the ones that exploded already, but a recall is about the ones that haven't exploded yet.


When you decide whether a risk is unacceptable, there are two parts to consider: the likelihood of the event, and the potential worst-case scenario should the event come to pass. .01% is a very low likelihood, but the worst case scenario that one of these phones maims the user is an extremely bad outcome. In this framework the recall is the most sensible thing to do.


Do you have a source for that number?


The correct response for when someone asks your wife why she doesn't have shiny carbon on her ring is, "because fuck you, that's why."


This is a joke. There is definitely no extension cable.
