Beware of family jewels if you're carrying WM7 phone in your front pants pocket.

WOW, there are a lot os sick people but this is the sickest of all
I'm not looking for knee jerk reaction to this video. This is a valid question from someone who's familiar with four corner testing which includes thermal testing. The correct behavior is to shut down once a temperature threshold is reached as seen with the Android and iOS devices. The WM7 device dangerously continues to operate beyond threshold.

then ask for a normal reaction , if you only post this video from an idiot burning 3 of the most expensive phones on a grill you can expect these reactions .

No need to get emotional. This is a silly stunt video indeed but there is something to gain from it since it might expose the lack of or malfunction of thermal shutdown protection in WM7. A lot of people including myself keep their phone in their front pants pocket. Why wouldn't they be concerned f thermal shutdown protection isn't working and knowing that lithium batteries can be unpredictable when exceeding normal operating temperature?
Lithium batteries explode because of impurities in the electrolyte (or whatever it's called there) causing short circuits. This is purely an internal condition, and no thermal shutdown protection will save your gonads if it happens. So relax and get a life really.

Wrong dear. This thread doesn't apply to you if you have no family jewels.

"batteries could overheat, potentially causing burns, an explosion or a fire"
"If the battery gets hot through use or recharging, the pieces of metal can move around, much like grains of rice in a pot of water. If a piece of metal gets too close to the separator, it can puncture the separator and cause a short circuit. There are a few possible scenarios for what can go wrong in the case of a short circuit:
If it creates a spark, the flammable liquid can ignite, causing a fire.
If it causes the temperature inside the battery to rise rapidly, the battery can explode due to the increased pressure."
and we see all 3 devices explode at the end of the video (I don't know which version is linked, the one I saw yesterday had all 3's batteries swell and burst, and the flames flared up)

Why is he an idiot? If I could afford to cook three expensive phones, I'd probably have the kind of job an idiot wouldn't. Please explain.

Nice detective work there... you quoted a laptop battery article.
This has nothing to do with Windows Phone 7 and is mere sensationalism to create a non-fact base, non-realistic controversy.
Btw if you create a spark or rapidly rise the temperature on anything, it usually catches on fire or explodes. That applies to 99% of everything on this planet.
I'm not sure if it really matters. As someone mentioned, all three ended up going because they were continually exposed to the high temperature. Simply shutting the device down wouldn't prevent that in this scenario.
Lesson learned: don't grill your phone.

you have to look the other way around ( that was external heating , if that was the way you would be already dead before the phone explode )
the os has to shut down when it get internally hot ( like a software bug , overcharging the batt , or a gps + wifi making the phone go hot )
and that is there , when I turn on wifi and gps and I am charging the batt the phone will reboot after some time (it reboot because it is on charge )
edit: I only think it is a bug that the phone reboot after a shutdown by overheating.
edit: ps it is WP7 and not WM7

Amen to that brother!
No but really. The point is that the phone doesn't shut down if it would overheat on it's own. So, say that the phone by some reason should overheat to the point where there is a risk of the battery exploding.
i think if you phone gets hot enough to need to shut down...it's over anyway. Shutting down automatically isn't gonna save anything. There will be no cases of burnt faces like with the iPhone

It must be true cause I saw it on the Internet.
There are some who get it and the majority who don't. Unfortunately, the majority think that the HTC WP7 won while the HTC Android failed in the video. Or, that the added cost of thermal shutdown protection now built into phones is not there for a reason. Or, those that keep stating the obvious that lithium batteries burst when exposed to fire but fail to comprehend how the phone should've behave prior to reaching that critical point. These are probably the same people who will argue that a faulty smoke detector is of no consequence because houses seldom catch on fire or that you would know about it if it happened without a working smoke detector or that it would be too late even with a functional smoke detector. To each his own ballz. Let Darwin sort them out.

Ok so half or over half of most my days are spent in a subzero freezer unloading freight ect.. My question is this, am I doing any harm to my EVO by keeping it in my pocket while im in the freezer the phone does get rather cold while im in there im just wondering how much if any damage im inflicting on my EVO and should i try to find another place to keep it while im working?
no i believe you do not your body heat should provide some heat to protect it ..just remember if it gets under 32f your phone might get permanent freeze damage thats if you leave it in there. lol just keep it in your pocket
I would only worry about moisture intrusion. It may not affect the phone but it may cause your water damage tape to react thus voiding your warranty for water damage.
i wouldn't bring it in the freezer with you. keep it locked up somewhere.
As long as your phone is kept in your undermost layer of clothes. I can't see any reason why it would be damaged by the cold. I would imagine your body heat would keep it around forty or fifty degrees, which is perfectly safe.

I don't think the cold itself will hurt it, I would just be carefull of condensation that could form when it warms up.
Like was said earlier, it will probably be ok if you keep it in your pocket.
Most electronics dont mind the cold (those that use some kind of bulb are the eception normally). As others have said the problem is more likely the condensation or moisture that could occur from the rapid cooling or heating.
if it is under layers of clothing it should be fine but it is probably best not to take it in the freezer.

You should be just fine while in the cold. Lower temperatures, even freezing temperatures, will not impede the Evo operation; they may in fact prolong the battery life.
The problem is going to be taking a cold Evo outside, and having moisture condense on the phone. I would get a plastic bag, and put the evo inside just before walking out of the freezer.
I know the Evo is one cool phone but no reason to freeze it. Do you use it while in the freezer? What are you doing in the freezer?
I would recommend keeping it somewhere else if at all possible.
left mine on a box while lumping a reefer, -15°f for an hour, no ill effects, but if you do something like that make sure you warm it back up slowly and don't breathe near it, condensation will make you cry
Actually how hot can the phone sustain without damaging it? Cuz I plan to put my phone inside my car during my sch lesson ( where my sch inhibit students bringing phone during lesson or else will get confiscated ) , but the hot weather make me worry bout hw hot the phone will able to be sustained without creating any damages on it?

its a strange question because it hasn´t measure for it logically

Hi Bert2662
I've been asking myself this question before. As the country I am living in, Malaysia, is hot and humid kinda whether. Constantly it will make my battery temperature on an average of 32'C.
I guess it should not exceed 35'C, as it is considered quite hot already. I am using a casing for my Desire HD, and even with that, I can feel that my hands became pretty hot.
Based on my own feeling(no empirical evidence. Lol.), that it should not exceed 35'C as it can damage your battery first, then hardware.

Hei, I'm also from I'm from Penang! I also have my phone with a cover. But I think the temperature in the car rili nt suits it.. Lol..
lol..i'm from selangor!! Anyway, i read some where saying that max battery temperature should not more than 40C, it will reduce battery life or damage it later. As for CPU, and electronic item, max temperature should not exceed 50C.
Edit: When I use my phone for browse especially, temprature getting increase very fast. Especially when you outside during hot wheater. Just in 1 to 2 minute, battery temperature already reach up to 40 ~ 42C!!
Hi Malaysians! Oh, i live in Selangor too.
Yea.. I reached once at approx 40'C and that time i do not feel secure anymore. (again, based on feelings. Lol.) From that day onwards whenever I have the chance to cooldown my phone i will just leave the phone on the table to have some air-con. Of course not for places like mamak, but places like in offices. Lol.
Lol!! The hot weather make me feel no longer think bout to put my phone inside d car. Unless I cn park inside d sch cuz currently I park my car outside d sch. By the way, it's good to separate the battery frm the phone if I rili need to put d phone inside d car

Remove the battery? Perhaps you bring along the battery with you wherever you go and leave the phone inside the car. Lol.
By the way, if you really want to do that, make sure you do take the battery with you. I notice many people has lost their valuables is because they left something in their cars. Well not much about the battery, but i heard that they have sensors to detect batteries or something metal for such as laptops and handphones. The Desire HD is also made up of aluminium. So.. Lol. You decide.
Again, this is what i heard only. How true is it will depends on how you look at it.
I'd just take it with me to class, turn it off and hide it (in a bag or something).
Problem solved
One a side note, I don't believe that schools have the legal right to confiscate your property, but it might get you into all kinds of other trouble.
Hi frosty_ice
Yea.. school do not have the legal right. But they will still confiscate your phone. I guess it applies to most schools around the globe. Probably private schools have more flexibility. Well you can bring your phone, but you have to give the teacher to hold them for you. Ish.
you dont have to lay your phone onto the table ^^

she was on while charging, after i take off the charger the tablet still work 100% ( i guess), but i turned off because was too hot.
The heat was coming from the place where you put the charger. ( i guess was a factory error in the charger and was heat too much, i don´t know)
I´m afraid in the moment i get the tablet to samsung they say that was me that dropped to the ground and broke the screen.
Either the battery expanded and broke the panel or something related to the battery. Im not sure if samsung will replace that.. How old is this tablet?
I would make sure to add a note (hand written message) when returning it to Samsung that you have included the charger and the cable for them to test and I would tape a note to the back of the tablet so they can't say they didn't see it and take pictures of the note taped to the tablet.
If you were charging it with the factory charger and the cable as per the instructions I would fight them to the end for a replacement!
That hole is obviously made by external forces. If it was caused by heat or battery expansion it wouldn't look like that. Either you smashed something onto it or someone else did.

If you are adamant that no one else could have man handled your tablet while you were out, the other possible explanation is that your tablet experienced some extreme temperature and had a pre existing weak point at that position (micro fractures can be invisible to the eye).
It is unlikely that your battery could have become hot enough to crack your screen without bursting into flames first, so the other extreme is more likely. Is there a chance that the ambient temperature of your office dropped to freezing or near freezing while you were away?

No one enter my office because i locked after leaving. And the temperature was always the same, ambient temperature. 10 to 15° celsius.
Most probable scenario is that someone physically damaged the unit since you did leave it unattended. Achems Razor will help cut to the truth.

I'm interested in buying this tablet which is how I've ended up here (new to the community).
Having some experience with lithium-polymer batteries from hobbies of mine, my first thought was 'what type of battery does it have?' Li-Po batteries have a tendency to expand and potentially catch alight if 'gone dodgy' or over-charged. The Galaxy Tab S uses a Lithium-Ion battery which it turns out can have similar behaviour.
This could well explain the state of the tablet (and the heat). It might not have caught alight with a standard charger, or you got to it before it did. Either way, good thing you got to it when you did!
I can't post any external links yet as I'm still too new, but googling "Lithium Ion battery expansion" and "explosion" shows some examples of what can happen to these batteries (although I don't believe this to be very common).
This type of expansion force from inside the unit would most likely burst the screen and I can only imagine that being pretty nasty, and possibly the cause of the state that your tablet was in.
I trust that you got it replaced through your warranty without any quibble?!..

First of all, I'm not a noob regarding electronics and batteries.... Second, I don't think Samsung did such a stupid mistake like using millions of batteries without testing them and third, I don't think that a company who is producing batteries for a mammoth like Samsung can afford to sell defective batteries, or not properly tested batteries...
I'm the owner of a blue Note 7, and I am ready to take the chance and NOT exchanging the phone.
And this is why:
(please excuse my English...)
At the beginning, I have noticed that every single time when I was charging my phone, the phone was kinda overheating... Not too much, but still....
After that, the big scandal about exploding batteries was everywhere in the media...
I have read in the phone settings that SPEED CHARGING can overheat your phone (actually is overheating just the battery)....
So I've just disabled the speed charging on the phone and the now the phone is always cool
So my personal opinion:
I think that the problem is somewhere in the speed charging process, something that is shocking and putting too much pressure on the batteries, probably not proper designed for fast charging.
So I'm taking the risk and not exchanging my phone, and I suggest to all of you guys who are not exchanging your devices to do the same, especially because the charging speed is not too much different regarding the speed!!!
Please test and post your experience regarding charging speed and phone temperature with the fast charging option enabled/disabled....
Thanks, and again, this is my personal opinion, and I'm not advising anyone NOT to exchange the phone.
Just a couple of points on your post.
1. It's not all phones that have the reported problem - Samsung have a few different battery suppliers and only one has delivered faulty ones. The problem is that Sam has no record of which phones they went into.
2. Phones sold in China have not been recalled because Sam knows the dud batteries weren't used for that batch.
So a general charging problem doesn't explain the situation. But yes of course fast charging will make the battery hot.
My personal opinion what is the big deal no sweat off your back. Change the phine and get it over with.
The liability you are assuming is not worth a few hours of set up
on the testing front, it is impossible and far too time consuming and detrimental to the product to conduct full scale testing on every single thing coming out of a factory, the fact is mass production should make it so item 1 and item 1 million are identical, so due to the process they will do spot checks randomly testing say 1 in 100, now when you hit a problem like this battery fault where the actual fault is a very very small percentage it's like trying to find a needle in a haystack, you can poke at it randomly as is the industry norm (even with cars) but the majority of the time you are going to come out with hay. the only way this could have been caught if every single battery was put through intensive inspection and usage tests before they shipped, not only would this add a massive amount to the production cost and time it would also lead to the battery already having some pretty harsh wear and tear on it.
so the testing is pretty much manufacturing standard and the same as every other company worldwide, so if Samsung for doing this then you are saying every single company the world over is stupid.
on not exchanging the phone if the option is there it would be stupid not to, as basically if it does fail down the road and you refused the recall then you have no come back as you were told and given the chance to have a device deemed to be safe.
the fast charging claim was made up by phone shops, it's not one Samsung ever put forward. yes fast charging can generate increased heat, but the battery isn't failing because it is hot, it is hot because it fails. the actual failure of the battery is a short circuit caused by a fault making the 2 sides of the battery to bridge leading to the battery to have a runaway reaction, you can actually do this on any battery should you use something to short both sides of the battery together. now here lies the problem, people erroneously claim don't fast charge as it reduces heat, but when the flaw comes from parts of the battery that should never touch coming into contact with each other, slow charge or fast charge if them 2 parts are close enough they can touch they will eventually. so yeah heat is a symptom not a cause, with temperature things can expand and contract but the fact is if the short can be made on a device anything you do is only delaying the inevitable and there is nothing you can do to stop it eventually failing.
but end of the day if you want to risk it and live with 60% battery power that is up to you.
I agree that the vast majority of batteries are probably fine.
The hassle of keeping will be having to deal with airports, gimped 80% battery and possibly IMEI blacklist.
The hassle of exchanging is getting a unit with screen or hardware other problems. As well as (like in my cause) having to exchange out of region, the process of which still isnt clear to me. I am currently playing ping pong with samsung UK and samsung Gulf (i am the ball)

My note 7 to heated up too during that one time during its first w days. It was really really hot...I turned off fast charging and it never happened again.
I also believe it's related to fast charging...which is on by default.
Using generic adapters and cables hasn't made it hot every since i turned off fast charging.
But I'm still having this replaced..sad because I have no problems with this unit..GPS works perfectly and fast. Battery last long. And now the news is reporting that the new note 7 replacements are showing problems is South Korea. Over heating and not charging....sigh

the updates have to be done in order you can't skip one and go onto the next, if you get the next it will include this one so basically using that method you can never update the phone.

I have read in the phone settings that SPEED CHARGING can overheat your phone (actually is overheating just the battery)....
So I've just disabled the speed charging on the phone and the now the phone is always cool
So my personal opinion:
I think that the problem is somewhere in the speed charging process, something that is shocking and putting too much pressure on the batteries, probably not proper designed for fast charging.
So I'm taking the risk and not exchanging my phone, and I suggest to all of you guys who are not exchanging your devices to do the same, especially because the charging speed is not too much different regarding the speed!!!
Please test and post your experience regarding charging speed and phone temperature with the fast charging option enabled/disabled....
Thanks, and again, this is my personal opinion, and I'm not advising anyone NOT to exchange the phone.

I agree with you 100%, through my own testing i came to the same conclusion which included charging from power point/usb and wireless, i believe heavy use, fast charge and a defective battery caused issues, not just battery issue , in my humble opinion i believe incorrect using of fast charging was probably an issue in all legit cases, but Samsung should of put some type of time limit for fast charging, ie 90 minutes, that way would of negated one part of the equation and probably stopped a few bangs, so blame all around really
If it was fast charging that was the problem don't you think samsung would have disabled it with the replacement phones?
Kudos for starting the thread by stating what's said is "your opinion." We're all operating off of second and third hand data yet some here will defend their interpretations as fact. Clearly they're not and can't be.
This explains the battery issue. If fast charging made batteries overheat than you'd see events like this on every forum for every OEM. S7's don't have this issue and they are only three months behind the Note7 in development and share many of the same internals.

I'm glad that i left Samsung family cuz It was pretty damn sure that someday my phone will kill me
Samsung is going the apple way i guess.... Just to sell it... Now apple doesnt look that expensive.... :/

First of all, I'm not a noob regarding electronics and batteries.... Second, I don't think Samsung did such a stupid mistake like using millions of batteries without testing them and third, I don't think that a company who is producing batteries for a mammoth like Samsung can afford to sell defective batteries, or not properly tested batteries...
I'm the owner of a blue Note 7, and I am ready to take the chance and NOT exchanging the phone.
And this is why:

Yes, you are a noob, you don't know anything about batteries.
Current Li-ion batteries can be safely charged with approximately 40 watts of power. Fast charging in Samsung phones utilizes only 15 or so watts.
It's not the fast charging. It's a just a tiny percentage of batteries with a defect.
I fast charge mine all the time and it stays pretty cool. I'll still switch when my replacement arrived, but in the meantime I am not worried.
just curious can note 7 avoid this catastrophe if the battery was removeable ,what are your views ?
Since we don't know what the cause was, my opinion is I don't know (well, I read something I haven't seen anywhere on the boards or any other news source but one but I won't state it because I have been accused of reading the news, it is in a language most won't understand anyway). But I am confident they should be able to fix the issue. I would largely prefer them to keep the IP68 rating.
You asked for some views so here are mine, much to the chagrin of many I'm sure but that's ok, that's just fine, really.
Based on currently available information which includes how Li-Ion batteries actually work, I personally would say the actual reason(s) that the Note 7 devices are considered to be defective is not because of the battery itself. So, while having a removable battery is a great thing - and I prefer devices that have removable batteries personally and only buy such devices with my own cash (I got my GS7A as a trade for a laptop so it didn't cost me any cash out of pocket).
Try this hypothetical situation for just a moment, if you will.
Without naming name brands or particular models, say you have a smartphone that has a removable back cover and a removable battery inside. To get to that battery and remove it you must handle the device well enough to be able to get at the back cover, probably find the tiny little gap that most have so you can insert a fingernail into it or perhaps a nail file, a butter knife, anything at all that can fit in that little gap so you can then start to lift the back cover off the device, unsnapping the retainer clips as you do so.
Follow me so far?
After the back cover is fully removed from the device you then have to remove the actual battery itself. Most removable batteries have a spot where you can "hook" a fingernail into and then pull gently to pry the battery up and out of the frame of the phone itself. If necessary you can probably turn the smartphone display side up and then smack the phone into your palm and the battery would probably drop out into hand, but generally most people just use their fingernail or perhaps a spudger to pry the battery loose from the device.
Voila, you've removed the battery entirely, congratulations.
Now here's where it gets interesting:
Say this smartphone has a defect that is occurring at random times on some devices - some of them will exhibit the defect (as cause and effect) and some devices may never exhibit it because of the random nature of how it presents itself. Considering this random nature of the defect presenting itself, say that at some point either while you are actually using your smartphone in your hand, or it's in your pocket, or it's mounted to your dash in your car with a holder, or it's sitting on a desk or table, or anywhere at all really and...
It starts smoking.
I mean it literally starts smoking and the smoke is quiet visible and you can see it easily. You can even smell it as it's happening. If the phone is in your hand when it starts smoking your most common reaction will be to drop the device right then and there, especially if in addition to the smoke you feel some heat buildup, like it was somewhat cool a few seconds ago but now it's smoking and it's getting damned hot, fast.
Again, most people in that situation are going to drop the device immediately.
But your device has a removable battery under the removable back cover, right? So...
If you dropped the device because it was smoking and getting hot there's a chance, a small chance but a chance nonetheless, that in the act of dropping your device when it hits the ground or it lands on a desktop or table top it might just cause the back cover to pop off and the battery might just pop out of the device entirely. That's a possible thing, right, you can actually imagine that dropping a smartphone with a removable back cover and removable battery might just make the back cover pop off and the battery pop out.
Still following me? Good but here's my point.
If you have a smartphone and it starts smoking, anywhere - be it in your hand, pocket, dash holder, tripod holder for pictures, on a flat surface, in a pool, under water, in a toilet, desktop, table, gravel, dirt, sand, on a road, it doesn't matter - the primary way to get the battery out of that device means you have to remove the back cover and then remove the battery and that requires you to hold it but since it's smoking and getting hotter by the second that's not really an option anymore.
So what then? Does that mean having a removable battery is a bad thing? Well, no, not really, but in a situation where the device fails in some manner and causes - that's the important thing here, the cause - the battery to fail as well and burn itself up it means you could potentially suffer some injury yourself because you have to manually remove the back cover then the battery.
tl;dr Yes it's a good thing to have a removable battery, but if a device with a removable battery fails and you want to remove the battery during the failure hoping to save the device itself from further damage, you might be injured yourself because you have to handle the device to some degree to get that failing battery out before it does damage the device or in the most extreme situation explode which destroys the device and also might release the gases from the battery which are incredibly toxic to humans.
I'm just speculating here.
My answer is: Maybe.
If I read is correct and the fault lies with the design flaw more than a battery defect, having removable battery would mean losing water resistance and the curve design, and maybe not apply too much pressure on to the physical battery itself.
What I do know is, if we had removable battery, Samsung would have avoided a full on major recall and just exchange the battery. If size is a problem, maybe a smaller capacity in exchange for safety. And maybe a small refund or a token of gesture to make up for the smaller capacity.
Oh well. What a waste.

IF the battery is-was the problem then your question has an obvious answer. WE don't know yet what the problem is so no one can yet say.
Its yet more of these threads with yet more speculation over a done and dusted deal.

I do agree with broadband. Even with removable batteries, if the batteries were damage, I wont be fast enough to remove it to prevent total loss.
But yah, it will drastically affect the recall process. Recall batteries are still better than the whole phone. And there will be plentybof after market alternatives to tide over temporarily
One of the reason is also easy troubleshooting , but a faulty set is needed to test the theory, example a faulty note 7 came with a removable battery, reports states that it will get extremely hot before smoking up, sure many of you who own Samsung older version of phones, changing battery is quite fast if the techniques is right, ok just a example, if the first one is a sdi battery as claimed, went faulty, threw it off before smoking up.
Went to claim from Samsung, which is ampere battery(forgot the name), if it didn't does a thermal? What's the deduction then?
If the second battery did smoke up, high chance its the phone issue? Of course this is just a theory, with all the reported note 7 smoking up and burned like crisp, it's quite hard to csi it.
Based on my observations, it seems like the replacement units are more prone to blowing up than the original. Even with the ATL batteries.
