Beware of family jewels if you're carrying WM7 phone in your front pants pocket.
http://www.youtube.com/watch?v=Gm0AkFUYpLQ&feature=player_embedded
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.

"I'm not looking for knee jerk reaction"
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.
http://computer.howstuffworks.com/dell-battery-fire.htm
"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.

I think you don't get it. The whole scenario and entering arguments for this are unrealistic and ridiculous. Nobody cares.
So I just got the Galaxy Nexus (upgraded from the Nexus S) and just after the first day of use (no heavy workload, wifi or GPS) this thing became painfully hot. We're talking touch it to your skin and *ouch* hot. Strangely the massive heat output seems to be limited to just the top quarter of the device. Also note that it takes only about 10min until it reaches 'unusable' status.
Does anyone else have experience with this problem? Admittedly I was warned by the provider I got it from that they had had feedback from customers about it's excessive heat output and other people I know have also commented to the same affect. But I never thought it would be quite this bad. I could fry an egg on this thing. Considering my Nexus S never had this issue - this is disappointing. Are we talking hardware design fail? Or perhaps a bad batch in my country?
If this was an iPhone they'd be headlines going on about 'heat-gate' and Larry Page coming out saying that we're 'cooling it wrong' lol
the nexus does get abit hot around the camera area, but it shouldnt be THAT hot lol.. what are the ambient tempreatures around where you're using the phone?

Not that hot - maybe 20-25c
Perhaps monitor battery temp with an app, it won't give you a precise indication of your processor temp, but there should be a correlation. The phone does get warm around the camera area, but never painfully so (for me). Was your AOS usage abnormally high?
I think the OP is overreacting just a little, if it burned you then the phone would have melted
Anyways, its perfectly normal. the OMAP4 chipset runs really hot, I read somewhere that it operates normally between 85-105 degrees Fahrenheit.
Here it says that the OMAP4 platform has a temperature range of -40° to 85°C. I think thats overstating it, but its all there

Well let me put it this way. It's hot enough for me to consider claiming on warranty. No phone should generate that much heat right next to your head/ear. That's unusable in real terms (at least with this particular one). And i've had my fair share of android phones in the past to compare...

The Tegra2 chipset runs VERY hot when overclocked as well, I've had hot experiences on both my Galaxy Tab 10.1 and my G2x, and I can also say that the OMAP4 runs hotter than that! Just offering opinion is all, it's perfectly normal for it to be running extra hot, and it happens fairly quickly.
I completely agree with you that the phone does get abnormally hot, but then again, from my experience, so does the RAZR with a sister chip in it.

Android 4.0.1, stock Nexus Galaxy, going on 2 weeks. It's in an otterbox defender case, after 1.5 hours of running video it's warm in my hands, but that's under constant workload that nearly drained the whole battery. In other words during normal operation I am not finding the serious problem you are describing. Empathy out to you.
What temps we're talking about? Mine stays at +36C +38C while browsing web/watching youtube and gets a bit (around +41C) hotter when playing games. And these temps are far from hot-to-touch.

Sometimes my GN becomes really hot too. It also happens when i'm watching hd video for a half an hour or more. Then it turns terribly hot.
mine goes to 48C and then it starts lagging like hell
Mine gets warm around the camera and earpiece. It's pretty normal, I'd say.

There are multiple threads on this, but I'll say what I've said before: it's a dual core device, it runs hot, it's not "overheating" unless your phone is crashing, shutting down, or otherwise obviously malfunctioning in some way other than getting hot.
What do you mean by "it reaches 'unusable' status" though? Are you just afraid of using it because it seems hot? Mine gets quite hot when I use it heavily...have kept it going for several hours in this state (while plugged in) with no other issues.
Mine gets hot in the same area, but it has never been that hot, just warm. My OG Droid was OCd to 1.3ghz and that literally reached 150+ degrees F quite a few times and is still fine to this day. The OMAP SoCs seem to run a bit hotter than others, but they can definitely handle the heat.

Basically out of the many smart phones i've had in the past. This is the first that I would say I would refuse to hold it up next to my ear due to the excessive heat. It's bad enough just holding it landscape to type on let alone sticking next to my head. It's really annoying considering how otherwise the interface and physical design of the device is better then anything else i've seen on the market.
I think i'm going to get one of those laser thermometers to find just what the temp on the surface of this thing actually is.

It's hot on the back of the phone like other uses have said, not the front where your ear would be (unless it is which is an entirely different problem). Plus, when your phone reaches those temps through extraneous use (videos, games), you normally wouldn't be putting it near your ear anyways. I don't see this as a huge issue. If you do something taxing, much like a computer, expect the phone to work a little bit harder and hotter.
Oh and I doubt it's hot enough to fry an egg. You would smell the plastic melt first.
I've had once when my GNex was really hot. It was when I try factory reset many times since there was a bug that factory reset does nothing in a custom rom. But I didn't know at that time. I tried reset, flash rom, reset, etc. My GNes ended up really hot.
The only time my galaxy nexus got really hot was when I was switching kernels every 2-3 days, and one kernel (I think it was one of Franco's earlier builds) made it run hot even when I wasn't using the phone that intensely. Changed the kernel, and it's never been hot since (I play games, listen to music, browse web, push notifications, etc.) I don't do much video/HD streaming though...
I have been getting that too. Around the earpiece gets warm when only slightly used. Also, I can hear a faint buzzing humming sound from there. Open the back cover..can hear it from the camera too. Is something wrong with my phone
I am thinking to buy the phone but I saw some posts there are some heat issues. So what is the problem besides the phone getting too hot? Is it shuting down when it gets too hot or get really laggy? Is there any other problem when heated except it gets really hot?

I haven't experienced any heat issues. I have yet to feel my g3 get warm Tbh.
Others (not sure which model) have reported issues with heat, to the point that it causes the device to throttle the brightness down. Again haven't experienced this on my at&t model.

Thanks for the reply, someone with issues ?
Same here not felt it get warm even watching video.
When the phone gets hot several things happen.
1) The CPU is clocked down to help lower heat
2) Brightness is capped to help lower heat
3) If the phone continues to get too hot (usually when its already hot and you then start to play a really intense game, or benchmark the phone may shut itself down.
People complained a lot with the Korean model but I haven't seen anyone with a US model complain. Maybe the type of person that waits is less likely to be a phone gamer? They may have actually tweaked it so it doesn't activate as quickly or harshly. I do know some people disabled it on the Korean model. I haven't heard of anything bad happening but those few people may have felt dumb if it destroyed their phone and not posted that it did...
I have no heating problem with my lg g3 international D855 16gb model, even during quadrant test or playing games.

Define an actual temperature for hot.
I disabled the thermal protection on my AT&T version and yes, I've felt it get quite hot while playing Final Fantasy 6. The heat radiated mainly through the metal power button but the entire top half of the device got pretty hot. Didn't bother me all that much tho, as I've had other devices get hot like that in the past.
I use exposed app CPU temp my g3 sits at about 30c and 45c which is normal temps and about 50ish whith thermal protection on disabled.

My girlfriend picked this up yesterday and this is happening to her G3. Not playing games though, just browsing the internet/reading an article. It makes no sense to me. How can you take control over that? She doesn't want to root the phone.
But yeah, just reading something or even looking at Facebook, the phone gets way too hot.
I picked up the Verizon version yesterday. It's gotten pretty warm around the power button a few times for me also. Typically not bad or what I would consider unusual with one or two exceptions.
My G3 (UK) go very very hot yesterday when I was on the train playing a graphically intensive game.
It shut itself down and then refused to turn on again. Ever.
I tried everything all night but no joy. I got a replacement handset today.
I'm sure it was because of the overheating that the phone malfunctioned. Without knowing exactly what has happened to it the timing is too coincidental for it to be random hardware failure. It was SUPER hot!

This is strange. Does the kernel not shut the phone down before it "fries" the SOC?,unless the throttling temps are too high? Wonder if this is linked to the display flickering problem myself and another poster had.

Funny you mention display flickering. I had that about 2 weeks ago. The display started flickering really badly, like nothing I've ever seen on any Android device, and I needed to pull the battery to reset. It didn't boot straight away either, it had to cool down a bit.

Yeah, i had a flickering display which didnt go away.I returned that phone. Another poster yesterday had the same issue.Im wondering if the GPU is frying itself? Although the GPU does throttle as well as the CPU. Running Antutu I would get 60+deg C maybe playing a game for an extended period of time for example is causing damage? Just a theory.
I checked out a video with the G3 being pulled apart. Right under the power button, is a silver rectangular(ish) component. Can someone tell me what that part is?
I'd just like to understand the source of the heat.
Thanks in advance.
The source of the heat is your CPU which resides under the power button more of less. You will also notice that the display gets hot on the front top half. This isn't necessarily normal, were you doing anything CPU intensive? (Gaming, recording long 4k videos, streaming 2k videos etc...?) It won't hurt your phone but it shouldn't be hot to the touch but instead 'warm'
Thanks for your answer.
I'm finding that videoing for 2 minutes really starts making it hot.
I'm not rooted (yet) running 10j with a 16gb aus version.
Any suggestions would be appreciated. I'm not going to root until Android L has been out long enough to "settle" down.
I had overheat issue with my first G3, it would get really damn hot, took it back for a replacement, I suggest that, if you can.
Mine was shutting down due to temp and 100% stock, if they wont replace due to overheat then tell them it shuts down which it probably will eventually if it is that hot.
Another option is try a different launcher and disable any apps or background stuff in Settings/Apps/etc that you dont need then try video again.
Thanks for the suggestion. I could take it back but it would be my third g3. I suspect that its the 2gb of ram which is the issue. Because I live in Aus we only have a 16gb 855 version. I suspect that even with a replaced phone I would still have the heat. Its not enough to shut the phone down and not enough that I can't touch it. I stick with my original reasons for getting a g3 - best hardware I could get with a limit to the bloatware (ie not s5). I don't think I could handle the 5.9" nexus. All I can say is, if you can't handle the heat, get into the kitchen (and sample the ROM menu).
Thanks for your help

Hi everyone,
I just replaced my lg g7 display and frame(heatpipe included), added thermal paste(MX-4) and reasslembled all but back panel, because i wanted to make sure everything was working fine. Everything is actually working fine but the cpu temp when testing with "CPU Throttling test", where i see one core going up to 82° and the others beetween 70 and 80 degrees. I disassebled it once again to clean the thermal paste and re-apply it again(even so it looked well spreaded to me) and the temperature still is the same running the same test.
I thought that maybe temperature reading from the app wasn't accurate so I checked at the same time with "DevCheck" overlayed, yet this one shows temperatures even higher like 86° top.
Can anyone run the app "CPU Throttling test" and share the max temperature reached?
I doesn't need to run for like 5 minutes like it says in the app, 30 seconds was all it tooked for me to reach that 82° on the hottest core.
In my opinion, the heat pipe is damaged. My G7 is a second hand model that came with a non-fictional heat pipe. Saw that when I took it apart to change the display.
You could search for a replacement heat pipe on some online shopping websites, but do make sure they are functional units. I have seen some sellers selling harvested g7 heatpipes and they are definitely not harvested correctly. They likely cracked the heatpipe.
To test a heatpipe, immerse one end of it in warm water, you should feel the heat on the other end in a couple seconds. If you don't feel the heat, then it's quite likely the heatpipe is damaged.
Protip: You can measure the dimensions of the stock heatpipe and get a generic one with similar dimensions, it's not mandatory to get a g7 heatpipe.

Well, you could be right...
But I must say that I made several runs to check temps, and after doing one of 15 minutes the highest temp recorded was not so far off, 85°C to be exact and it seems like it's still running cooler that other smartphone with snapdragon 845(like op6, poco f1) because those do something up in the 90°C.
Don't know if I should just relax or be worried about it.
