Nokia Investigating Reported Cell Phone Explosions
Iphtashu Fitz writes "C|Net's news.com is reporting that a man in the Netherlands suffered burns to his leg when the Nokia phone in his pants pocket exploded. This is the second reported incident of Nokia phones exploding, the first one being back in August when a Dutch woman's phone exploded in her hand. Nokia blamed the first incident on a third party battery that the woman was using and warned customers to only use Nokia parts and accessories with their phones. However this most recent explosion involved a new Nokia phone with a Nokia battery installed."
Is it about to explode? Any links on what signs to look for before your cell phone battery explodes? A search for 'exploding battery' on Nokia.com didn't return any results. Seems like they should take a more proactive approach and at least issue a warning. I couldn't find any.
It was the hot Norwegian climate?
Is that an exploding cell phone in your pants, or are you just happy to see me?

This reminds me of the bad capacaters that showed up on a bunch of motherboards a couple of years ago. I wonder if these exploding batteries are the result of industrial esponage gone wrong line in the caps case?
Can you hear me now? ;)
Would it be wrong to laugh at something like this? I mean, just imagine how funny it would be watching this happen to somebody while they were talking.

well, I've always bought nokia because they survive any fall (I even saw a nokia 3320 fall four floors and survive... cracked shell, but the phone worked) but now you've kind of made me nervous...
...you know those two poor souls would be getting sued by the company right about now.

He had his cellphone in his Pocket and burned Just His Legs. I'll not be slipping my Nokia in my pocket again. My wife and I would like to have one more child.
This is getting to sound like the story last year where the guy in England burned his crank on a laptop that got hot while he was engrossed in porn.
If people are uncomfortable with a hot phone on their ear, perhaps try a headset?
Maybe also keep your phone somewhere that the terminals don't get shorted out with gum wrappers or whatever.
This shows that Nokia obviously needs to work more on product testing. I mean you expect cell phones to have problems with software or something minor. Sounds more like a prank cell phone then a real one.

It's not a dupe but it's the same story.
What's the DTMF sequence to make the phone explode, so I can blow the next telemarketer's phone?????
I saw a local news report last night about the same thing. In Utah. I don't remember what channel it was on, but I assumed it was an isolated incident. Maybe there's something more to it...

now Nokia can't use explosions as an excuse to sell more of their parts. And they thought putting 'prizes' in some of the phones would help them sell more.
-Tim Louden
Does anybody know what is actually exploding? Is it the battery? Is it the CPU? Is it one of the memory chips? "The telephone is exploding" is almost as vague "his house blew up".

I never wanted a cellphone before, but if I'm promised pyrotechnics...
Banaaaana!
what the Isreali Mossad used to (and probably still do) to suspected terrorist phones. Inside agent would swap his phone with one modified with plastic explosives. Then they would call the terrories, and when he put his ear to phone it would blow it off.
I question what do you mean by explode... Did some of the battery acid spill out??? or are we like talking fire and brimstone here??? I would think most likely the battery just burst, aka the acid leaving the battery case.. but the article really does not say.
It's not a dupe. The previous article involved third-party batteries, which Nokia could blame for being faulty.
What's scary this time is that, apparently, this was an original, first-party battery.
Maybe he will think twice about leaving it on during the movie next time.

that story is about the first incident which we are told of in this article "the first one being back in August when a Dutch woman's phone exploded in her hand. Nokia blamed the first incident on a third party battery that the woman was using and warned customers to only use Nokia parts and accessories with their phones"
Remember, batteries are full of energy -- DUH! One defect and BAM! you have a little bomb after prolonged use. One reason you shouldn't throw them in a fire unless you are really drunk and have track shoes on.
Strange women lying in ponds distributing swords is no basis for a system of government.
Originally a tire company (!!!), Nokia has expanded quickly into other markets completely unrelated to the core of their business. Since they moved into the cell phone business, it seems to have become their top priority, however even this focus is slipping. They are turning towards building home entertainment appliances like set top boxes and TiVo-like devices. Unfortunately, like when they moved towards cell phones and their tire business suffered, their cell phone quality is sufferring because of this refocusing on new markets.
Perhaps the Finns really meant these as cleverly disguised grenades to hand out to citizen-soldiers in case the Russians invade again?
How is this redundant!?!
Safety first, please. And that is a serious remark to companies, burns are not fun.

I'm suspecting that this is the case...

I had a battery explode in my pocket before without any phone attached to it.
It didn't really explode it just started getting super fucking hot and burned my hand taking it out.
Very bizarre it felt like my pants where on fire but I look down and see nothing burning, I was totally baffled until I remember the battery.
Not a good time, feeling your leg burning with no apparent explanation...
Of course, this is an allegation that'd be hard to prove without insider verification. Or possibly, with some astute multimeter readings.
This is a rather extreme method of fighting off those people who talk very loud into their cellphone at the worst possible moment talking on and on and..

"This is the second reported incident of Nokia phones exploding, the first one being back in August when a Dutch woman's phone exploded in her hand." ;)
Actually, there have been two cases reported *this week* by The Register, as well as the one back in August, so it's not the second reported incident at all.
What I want to know is, when will we see the first exploding N-Gage?
...are both very volatile power systems. Being an remote-control electric flight enthusiast, I have heard too many stories about NiMH cells exploding ("it sounded like a shotgun blast!") and LiON batteries burning up cars. They are fine if they aren't damaged or defective -- but a NimH or especially LiON cells that have been damaged can be VERY dangerous.

Conclusion: You have a greater chance of dying in a car crash than having your mobile phone explode.
happened to 2 dutch ppl..i mean, 70-80% of the ppl in europe have a gsm, nokia's the marketleader...and it happens to be 2dutch ppl who get hit?
to conclude: dutch ppl should not be allowed to buy nokia gsm's..or any gsm for that matter
it is pathetic when people who disagree with opposing opinions call their links "goatse links".
you're not meant to read that article thing anyway ;)
The Register
has similar stories.
I think someone is spreading FUD here.
Probably not so really battery acid: mobile phone batteries are typically Lithium Ion rather than lead acid like a car battery that can leak acid.
The Lithium Ion batteries in modern phones burn very well, and can even explode. They heat up when they are being charged, and they can also heat up under load, i.e. when the phone is transmitting. The battery pack that you attach to the back of the phone usually contains not only one or more Li-Ion cells (each cell produces a nominal 4.2V and most phones operate with that), but a temperature sensor and a small circuit board with a protection circuit on it.
The temperature sensor is used during charging to cut out charge if the battery overheats, to avoid it catching fire and/or exploding. I'm not sure if phones also monitor the battery temperature during normal use.
The protection circuit on the output of the cell stops the battery from discharging too deeply, because Li-Ion batteries are hard to recharge if they go too flat. It also usually limits the output current (i.e. the speed at which the battery can be discharged) to prevent sparks or overloading and presumably overheating.
Despite the disadvantages (limited lifespan of the cell is another), lithium ion batteries offer important advantages over other types of battery technology. They are small and light, and can be partially discharged then recharged repeatedly.
The article doesn't go into the detail of the cause of the incident. It could have been the temperature sensor failing, resulting in overcharge. It could have been something totally unrelated, but it seems most likely to have been the battery: its the most obvious explosive part in the phone.
I'd previously been of the opinion that cell-phones are evil!! but now, I really really really want one! And if they could provide instructions in the manual for how to make them explode, preferably with a timer feature, then I'll buy a bundle!

Although the CNN story mostly talks about the previous problems with counterfit batteries. And not to sound too RTFA like, but the article at news.com _doesn't_ say that it was a Nokia battery. It says it was the original battery. So he could've bought a phone with a counterfit battery.

Initially INTEL came up with the idea, but their chief developer leaked the information after being tortured at Guantanamo Bay.
The bad capacitors on motherboards just leaked. It's rare to get one exploding, in fact you only would in a PSU, where there's substantially more current than in a cell phone.
Batteries don't explode in a cell phone situation. It's physically just not possible. Perhaps if they were charging and provided with an external power source that's greater than they can handle. They can certainly leak, they can get warm, but there's no way a battery in use in a device without external power can just "explode"
IMHO (as a cellphone hater), this is a feature. :)
explosions can be very distracting. Espescially if they happen an inch from your face or in your pocket -- or anywhere in your vehicle, for that matter. Even a headset won't save you there, buddy!
But, I wonder, if my phone exploded and caused an accident, could I sue the manufacturer?

My Panasonic EB-310TX (ATT) nearly blew up in my car. I left it on the cig lighter charger overnight.
Didn't think twice about doing so, cause:
A) It's a genuine Panasonic charger sold to me at an ATTWS store
2) Original Panasonic Li-Ion battery. No 3rd party junk here, and all of about 30 minutes of talk time.
D) The AC charger shuts off when the battery is charged.
Apparently the car charger isn't so smart. When I picked up that phone the next morning I dropped it real quick. It was too hot to hold. The battery pack had swelled enough to force it away from the phone body.
Needless to say, the phone was cooked. It would stay operational for all of about 10 seconds before powering off or rebooting. The ATTWS store tried a new battery for me, didn't help.
I ended up getting the Motorola T721. Now this is a nice phone, and I've yet to run down the battery, even after talking on it for 3 hours straight.
My point is, any Lithium/-ion/-polymer battery is made with a very reactive metal. If overcharged, it will get hot and leak gases, and lithium+gases+heat = Boom.
A field test for the new weapon of the Bush administration. Created for the Homeland Security department by Nokia, the phones are programmed to explode when called by a source number, known only by the CIA, and in conjuction with a 2 beep tone. Once the tone plays the phone explodes and blows the head of the suspected terrorist.
Perfecto!
BTW, I'm a Bush fan; however, I simply couldn't resist.

This is the second reported incident of Nokia phones exploding, the first one being back in August when a Dutch woman's phone exploded in her hand.
OT: someone set her up the bomb? seriously though, was she seriously injured? what kind of explosion was it? was it just a *poof* and lots of smoke or was it more of a *kaboom* - like a firework? i wouldn't be too worried about the former, but the latter scares the hell out of me. i've seen people who've had fireworks explode in their hands, and it's not pretty. much less what that sort of thing could do to your face/neck...
It might look like I'm standing motionless, but I'm actively waiting for my problems to go away
Damn it, I told my girlfriend that she just talked way too much on the phone...
I own a cell phone you insensitive clod!
You don't need nuclear batteries, you could charge them up anytime by plugging into one of these
I had a cellular phone relatively early, back in the days of 1993. It was a Sony. I stopped using it, and using cellphones all together after i started getting headaches after talking on them. Most worrisome to me was that the phone got uncomfortably hot when I talked on it for any significant time, and then afterwards I'd start feeling that heat in my brain, sorta the side I was the using the phone just deeper my ear, almost an inch or two inside. I concluded I could do without that considerable amount of radiation and I was unwilling to go through the Tobacco-industry-versus-consumers over-whether-smoking-is-bad-for-you several-decades-debate-before-the-corporate-spin-
That said though, the idea of something exploding in my pants is even more unwelcome. I assure you the contents of my pants might even be more sensitive than my head. I never understood people who were comfortable carrying their cellphones in their pants. Testicles are very sensitive to radiation and there is only a layer of skin covering them. I almost never carried my cellphone in my pocket. Recently i stopped using a laptop in my lap too, preferring to use it on a desk, or using some hard thick material such as a folder between me and it. Testicles are too precious.

I was worried about the fuel cells doing this when the first come out in laptops late next year or early 2005, but it looks like we dont need fuel cell powered devices to make things go boom.
:) (and dont want one)
I would have never expected a normal battery to expload. but if these can, is there a larger risk of fuel cells exploading? and if they do, wouldnt the explosion be much larger?
Just another reason why i dont need a mobile/cell phone

"One reason you shouldn't throw them in a fire unless you are really drunk and have track shoes on."
umm no. You shouldn't through an expendable material enclosed in a metal container no matter what it is. _That_ is why you don't through it in a fire, it has nothing to do with electricity.
If you discharge a battery above it's rated capacity, then you cause heat, and the current draw takes the place of a fire. ie: Causing excessive heating.
Humor, that is.
7210's are very old. Is it possible that the old battery just simply degraded to a dangerous level?
It makes sense that there would be a short usable life for rechargable batteries.

Coincidently I was looking at this stuff a couple of days ago. My Nokia 8250 had started turning itself off when in use. I wasn't sure whether it was the battery dying or the phone so I went to borrow a spare battery to test with.
When I opened the phone I noticed that rather than being flat the battery was bulging out as if it was pregnant. The bulge was enough that it was difficult to get the battery cover back on.
I now have a whole new phone (another Nokia, a 7250i).

I must wonder whether "exploding" is a media enhancement of the story. Were the burns thermal or acid (from electrolyte) in nature?
:)
I had (and still have) a Nokia 8210 which popped the battery cover off when its Li-ion cell expanded to three times its normal thickness while charging. Genuine Nokia battery on a genuine Nokia charger. The battery certainly didn't explode, wasn't even warm. The phone is due for an upgrade soon... how about an N-Gage?
Being an electric aircraft fanatic and, like most, eager to get back in the air again, fast charging NiCD and NiMH cells beyond their stated limits (supposedly 1-3C for NiCD's and 0.5-1.5C for NiMH's) is a common occurence. Although one or two packs have leaked electrolyte under this *harsh* treatment, I'm yet to see any actually explode.
Has anyone here actually seen a battery explode, or is this just urban myth?
There are 2 things I hate, people who drive and talk at the same time, and the Dutch (with exploding phones). Now if a Finnish person's Nokia blew up, I think there would be a national scare.
"This is you left and that's your left. This is your right and that's your right. You're gonna die!
I don't remember the details, but something about heat building up during the charging vaporized something inside, making the case rupture spraying acid all over the place. Apparently, the phone could still explode a few minutes after it had been disconnected.

So can people actually make batteries explode on purpose? I sure hope this car doesn't park under my appartment building.
Or are you just happy to see me?
You must know lit-ion batteries. They use a little "chip" insidide that determines the load-status of the battery and prevents overloading. This same chip communicates tha available power to the phone. It would be very simple to send some extra undocumented data to the phone.
Just disassable more batteries, and use a scope and some day you will find the truth

Code, Hardware, stuff like that.
Accoding to this news (sorry, in Finnish) from today, Nokia denies that any original Nokia battery had ever exploded. Cheap third party batteries are a growing problem, because they usually lack safety components that prevent the battery from overheating when it's dropped or short circuiting.
(This sig intentionally left blank)
Lets get to the economics too. Adding such a thing with adequate protection mechanisms will require approximate 10000 gates microchip, plus some analog circuitry. This increase in cost does not justify this.
Moreover batteries are not replaced much nowadays(in GSM). Battery life for a meduim user is around 18 months, and after that time many people change phones. And one thing what people discount is that if such a thing happened we will have thousands of exploding phones, not just one or two. This is more of a freak error. Maybe some nokia phones have a defect which is masked by good quality batteries, or maybe batteries are not designed properly to take such loads.If you are really worried about this, don't. Your battery wont just explode. first the symptons come. If your battery heats up excessively while talking change it. And buy good quality batteries, manufactured by reliable manufacturers. Not necessarily nokia could be any comply

..what is probably the more significant link in the article. Worry less about 1-2 phones exploding per year, and more about the consequences 20 years down the line of putting a powerful microwave transmitter up to your head - to quote from the linked text:
Voice-only devices are giving way to real heavy Internet-ready devices with a lot more guts that, at least theoretically, may not be that great to have right next to your head, said Bryan Prohm, a wireless industry analyst at market research firm Dataquest.
"You lied to me! There is a Swansea!"
The heat you feel in a cell phone after talking on it for a time likely is due to the heating of the radio frequency (RF) power amplifier (PA) in the phone's transmitter, not the battery.
The PA must generate (depending on the type of phone you have--GSM, CDMA, etc.--the range to the cell tower, and other factors) somewhere between 0.2 and 1.0 Watts of RF power output. For lots of good reasons, and despite the best efforts of lots of engineers at lots of places, the conversion efficiency of battery power to RF power of cell phone PAs is around 35%--meaning that approximately two-thirds of the battery power consumed by the PA is converted to heat, instead of RF power, as you talk. Since everyone likes a small, light-weight cell phone, there is no dedicated heat sink (or external fan!) for the phone's PA; instead, most designs usually use the cell phone's frame to conduct the waste heat away from the PA. The frame, of course, conducts the heat to the outside world, which in this case includes your ear.
In many cases, to avoid the loss of an RF transmission line from the bottom to the top of the phone (which would result in even more inefficiency) the PA is placed next to the antenna, near the top of the phone--thus exacerbating the ear-heating effect. Since the heat generated by the PA has remained more-or-less constant over the years but the mass of the phone has decreased, the temperature the phone reaches in this situation has increased, making it more noticable. Handling this temperature rise is part of cell phone design, and one of the many tradeoffs that occur in them. Keep in mind that, since it is produced by energy stored in the battery that could otherwise be used to extend talk or standby time--two selling factors near and dear to the hearts of cell phone manufacturers--designers would eagerly reduce generated heat if they could do so without violating other design parameters, like product cost.
The type of heating you're experiencing sounds completely normal and safe to me. I would expect that heating of the battery itself would be unrelated to whether you talked on the phone or not. Rather, it would occur either (a) during charging with a defective or improperly designed charger, or (b) randomly, as a cell shorts out and its stored energy heats itself (and its neighbors) up, and the built-in protection circuitry either fails or (in off-brand batteries) is nonexistent. You can protect yourself against both of these possibilities (to below the lightning-strike and meteorite-collision probability levels) by simply buying and using name-brand batteries and chargers.
Sounds really exciting, just imagine how much more thrilling those phone calls are going to be never knowing if it'll explode at anytime - and with the rushed calls you're save money too

This is probably a Nokia engineers back door! She probably got a text message which contained the phrase "DIE DIE DIE" and this signalled the phone to short the lithium battery :)
Is it true they don't have text messages (SMS) in America - or was someone making that up?
Nick...
Link in swedish: Cellphone exploded in the hand of a 17-year old
Opps I set it to 'explode' instead of 'vibrate'.
Considering the number of phones Nokia have out there its remarkable that only one or two have GONE OFF EARLY...
goes a long way... forget the ear; it wouldn't take much to "blow your head clean off" (in the immortal words of Clint Eastwood).
I believe the Mossad also did this with the headrest of a car that a terrorist leader was driving... inventive folks, the Mossad... they're like geeks with an unlimited supply of high-explosives.
As an aside, that's one of the reasons why the Mossad is perhaps the most feared intelligence organ in the free world... they are (and have been) inventive, and ruthless. Apart from the occasional screw-up (the reputed botched assassination of a Moroccan waiter in Norway in the early 1970's is one example), they have carried out assassinations of terrorists in multiple locations in the world... mostly in the wake of the massacre of Israeli atheletes at the '72 olympics by Black September (a palestinian militant group).
The Mossad is very good at what they do... and exploding phones are one of their specialties.
Even if a man chops off your hand with a sword, you still have two nice, sharp bones to stick in his eyes.
Was it the mouse with the blue laser? If so... You now understand why MS switched to a blue laser!
Next thing, MS is going to file for a patent when you mouse communicate with MS server to report that it just crashed!
Try holding a piece of plastic against your ear for 20 minutes. That also get's uncomfortable and hot.
;)
Of course the phone generates some heat over time. I have no idea how that compares with the heat your body generates. Anyway, I have the feeling that a piece of plastic without any method of generating heat will also get uncomfortable if you hold it against your cheek for a long time.
I typically spend 2-3 hours speaking on the phone per day. I use a hands-free headset. Probably you'd also be better go by one...
... No, just my exploding cellphone.
I'm looking California... but feeling Minnesota...
Now Sweden and Ericsson will take the lead once again! Up yours, Finland!

... on a rooftop not too far away a sniper is annoyed he missed.
He was killed/by a cellular phone explosion/they scattered his ashes/across the ocean
Interesting. The Nokian Gazz has long been the tyre of choice for mountain unicyclists like myself. I always wondered if Nokian was somehow related to Nokia.
Mystery solved. +1 informative.
Oh, ok... so THAT'S why Nokia designed the N-Gage so that you have to take the thing apart and remove the battery to get to the game cartridge port.
That way when the battery explodes, the game cart won't be launched across the room, making it hard to find and retrieve.
The thing about this incident that I find concerning is that this phone exploded in the guys pocket when battery consumption is at its lowest.
1-800-BIGMAMA: "Now put the handset in your pocket, honey, and rub it up and down, YEAH LIKE THIS OHHH YeS YeS BABY GIVE IT TO MEE IM COMING BOOOOMMMM, _______ Huh ?, he just hung up . well another happy customer served.

From the story, it sounds like Nokia is blaming "unauthorized" third-party batteries for the problem.
In other news: Taking a cue from cellphone makers, inkjet printer makers announced they will incorporate exploding cartridge systems to prevent you from using cheaper, third-party ink in them.

The number 1 problem of working in a cubicle - 23 power cords, 1 outlet...
I heard on the radio the other day that in Great Britain, about twenty people each year get injured using, hold your breath: calculators!
After hearing that, nothing surprises me anymore...
It seems Nokia released some phones with movieOS in them.
Explode with the force of 1/4 stick of dynamite if the cells are faulty. And in this case, I'm willing to bet the cells in the aftermarket Nokia batteries are Sanyo brand. I won't go into further detail due to the NDA I had to sign. But I will say this, when sub-quality manufacturing goes into producing batteries, you have yourself a potential chemical BOMB!.
Life is not for the lazy.
I've heard that if Lithium is mixed with water, it explodes. Does anyone know if this is true?
I heard that an Australian army soldier was killed while walking in waist deep water when his (I guess typically badly treated) army radio battery got wet.
I'd love to know if this is true and Lithium is really *that* explosive?
War crimes, torture, lies, illegal spying... Would someone give Bush a blowjob, already, so he can be impeached?
