Does the lower part of your device back get warm after using it for 5-10 minutes web browsing or navigation or just fiddling? When holding in the hand you can clearly feel this warmth, but there is no overheating or burning (at least not now during the winter
its warm most of the time , but i am using this device so i guess it would generate some heat .
and i notice it even more when i have the device set to ROUTER sharing internet , then its even wamrer , depending on how far away the laptop is from the HD2 .
but it hasnt burned up , "YET " ............
/T
Mine gets really warm, no 3g here and a fairly stable gprs, so the phone isn't constantly signal hunting.
But it gets even worse if you charge it at the same time, and in fact when in the van and running a 1 amp ciggy lighter supply, the phone sometimes even says that there is not enough current to keep the phone running the current applications, and to shut some down, not good when bluetooth is needed, and running satnav, auto data updates then seem to be too much.
I dont know what current rating the htc car adaptor is, but if you buy a cheap crappy one from the carphone warehouse, i believe they are only rated at 500ma, the same as thier mains mini usb chargers
Big screen to keep powered up..........but gorgeous to boot!!!
The antenna is located in the lower back. On extended use it'll get warmer. You can also note this when making a long phonecall with phone in hand or using the internet for long time. If you charge it at the same time also the battery gets warm.
Cant say ive noticed it much with my hd2 but my diamond used to get really hot where the antenna was.
In the first days after I bought the phone, I've kept the screen on by mistake... It was in the leather case that comes along and I didn't realize it.
After about 3 or 4 hours, I've realized that the phone was rather hot. Removing it from the case revieled that keeping the screen on for a longer time will not only waste your battery, but even turn the phone in a frying pan.
You could test this if you browse some lame HTML web page, that doesn't have any scripts running in the background...
I'm not gonna answer the poll, purely because it doesn't have an appropriate answer for me.
The back of my HD2 gets warm when I use it intensively, like browsing the internet for 1/2 an hour via wifi, but doesn't get even slightly warm when I'm using it as a phone.
Anyway, it tells you in the manual that the phone will get warm when in use, so it's not as if no-one didn't know about it. We've all read the manual right?
Have you guys never used a smartphone before? It's perfectly normal that they get warm when you use them, especially with WiFi.

My point exactly.
However, it's more like a HD2 property to get very warm, almost hot when the huge screen is on for a longer period: this doesn't happen on other smartphone.
Then again, this could be taken as normal, given the screen size...
In conclusion, there's no need to warry!
P.S.: in case the phone is charging and the battery is way too hot, there is a feature that will automatically stop the charging process in order to prevent the battery from damaging (according to the manual johncmolyneux mentioned): good thing!

My Touch HD used to get a LOT hotter than the HD2. This is warm at best.
The Touch HD gets a lot hotter. The iPhone as well. Again, smartphones do get warm, that's perfectly normal.
haha.. it's an extra accessory for cooking.... There's even a secret setting to setup the temperature... To get serious, i think this is perfectly normal. I don't think it gets more than 35 degrees Celcius. I noticed it after hard use. Don't forget 10 years ago, 1Ghz processors with 10 times less power needed passive heatsinks 10 times the size of HD2..
For the iPhone, there's even an app to make it a hand warmer!
But I guess it drains the battery quite fast... and surfing or playing games certainly gives the same effect.
Problem is that it gets warm when charging too... there doesn't seem to be any thermal cutoff or battery full cutoff. I believe the excess heat when leaving the HD2 plugged in over one night is what killed my HD2.
The heat in mine stopped the touchscreen working until the phone cooled down so I've sent it back for replacement. A bit annoying as I was using the phone all the time so it got warm often. In some cases, I'd say it got hot, especially as it's summer here in Australia.
Has anyone else noticed a lot of heat near the bottom buttons front and back?

Yep. I can feel it
Not any more so than on my Captivate.
Can you check and post your battery's temperature? (you can have it using System Panel or many other system apps). Had a Galaxy S (Canadian version - i9000M) before and the battery was sometimes as high as 50-55 Celsius, which may or may not have had something to do with the internal SD card dying on many models. Hopefully the big Atrix battery doesn't have this problem.
yea this thing is kinda hot
I agree. It is noticeably warm.
I think we'll generally see some extra warmth because of the h/w, but we also got to remember, we're playing none stop with these suckers since they're new! Most of my phones got warm often the first few days...
Between h/w breaking in , battery breaking in, and users breaking in... i'm thinking its a non-issue (hoping its a non-issue!!)

Yeah im thinking the same
I'd still like something a *little* more scientific, like battery temp...
I've noticed the same thing, it's noticeably warm on the bottom. If it was the battery temp itself, you'd expect that to make the upper center warm, where the battery sits.
My battery is running at 32 deg C...I'll have to crank up some apps and see if that changes drastically in proportion to the bottom of the phone heat. Right now it's sitting mostly idle and doesn't feel as warm as I have noticed when playing around with it for a while.
It's most likely where the heatsink is dispersing most of the heat from the processors and other components. Keep in mind this thing has a dual core processor. This isn't your TI-83 graphing calculator from high school.

I don't think there is a "heat sink" http://tegradeveloper.nvidia.com/tegra/forum/heatsink-needed
ARM processors don't heat much, it has to be the battery that's causing this. Didn't know where the battery was, but it is kind of weird if the battery is near the top and the heat is near the bottom. Still sounds like a possible issue to me (I'm a heavy user - I *WILL* use it a lot every day, so it has to be able to "stand the heat"...)
I ran speedtest about 15 times in a row to get the phone to warm up. The battery is up to 37 deg c, the bottom of the phone is noticeably warmer than any spot on the battery.
the bottom edge of the battery is a good 1.5 inches away from the center of the "hot spot"on the bottom. I haven't seen a hardware tear down, but I'd guess there's nothing to worry about -It's not "hot", it's just warmer than the rest of the phone.
35c
my battery is running at 35c right now but is not where the heat i am feeling is located. This head is at the base of the phone near the bottom speaker.
Ok, well 30-something C seems fine to me. Could it be the LEDs used to light the buttons?
My nexus one got just about as warm if I played with it as much. So I don't find any issue with it.

Damn near everything in the phone that can generate heat is located in the bottom third of the form factor. This should explain why we can feel it.
The battery is in upper back of the phone.
I think it should be the baseband chip or the Tegra2 that making heat.
When I use the phone its warm just like my Captivate although everyday on my 30 minutes drive to work the phone gets really hot. I have tried it with and without the charger in it and its just hot regardless. Anyone else have the same experience while using the GPS for extended periods of time.
Does this device ever overheat like the Galaxy Nexus does?
Just curious.
in The Verge and Engadget reviews both said that it did not get very warm, even during their battery tests.
Tablets generally don't get as warm as the phones do because of the larger area for the heat to dissipate, and a lot of the tech that gets hot is in places where your hands normally wouldn't go.
Since when does the Galaxy Nexus overheat?

Thanks, preorder here I come.
Hey everyone so I decided to try the daydream VR since my friend has It. I spend about 45 minutes immerse in the experience and all of my sudden my phone shut off. I took it it out and the phone was extremely hot!! I thought maybe it was dead. So I plugged it in. And it dint do anything at all.. at this point I thought of the worse and thought my phone might have overheated and fried the internal. My friend suggested putting the phone next to the AC to cool down. And about 10 minutes of cooling the phone actually turned on..
All I can say is beware of long periods of time in the VR. I for sure will not be using this..
I posted on this as well the Daydream vr Pixel combo, is dangerous to say the least.
Mine heated up so bad in 5 minutes. i could feel the heat radiate to my face through the unit.
I had to pay for my Daydream a few days ago returning it may be my best option.

Were you using a case with your phone at the time, also out of interest as you mentioned AC, what is the climate like where you live?

I live In NY temp today was high 40s. And yea I did have a case. But I still don't think this is safe for your phone.

I agree it doesn't sound great, i doubt it will blow up on your face as the phone will self-power down long before then.
What case are you using out of interest? A thick silicon/rubber case will have a massive impact on the thermal performance on the phone. It will have the same effect as placing something over your computer fan outlet, eventually the system will shut down as the temp builds up.
On the bright side, I haven't seen any mention of any extreme thermal issues (phones will get warm when pushing VR content) so hopefully it is an isolated issue or is a software issue that can be patched.
Other than melting your face, how is the daydream experience?
Lol it is pretty nice,i found an app on the play store.
That had me in some girls bedroom while she was getting dressed.lol I was looking all around the bedroom.
Skydiving,bowling,etc.
Warning you will get dizzy.
That's a shame that it heats up that bad considering the phone has good thermals on its own. But it makes sense with the fabric insulating the phone keeping the heat from leaving efficiently.

There is no fabric that insulates the phone. The phone sits in plastic with rubber stand offs that space out the phone so it has a gap all around the phone.
I take my OtterBox commuter car off my phone when I use daydream and while the phone does get very hot I have not had a overheat message yet out has the phone shut down.

Ugh. Was hoping their would not be heat issues in the case...was so annoying taking my note 7 out of the case every time i wanted to VR...
Someone needs to come up with a case with a passive heatsink pf some sort on it.

Remember guys, any and all devices you leave the "light" on will get hot. Feel your TVs, even the LED get warm - hot.
While you're using the VR you've got the screen on and are taxing the Pixel in an enclosed visor. Plus your head is probably hot, esp if you're watching the prawn stars

yeah I tried my Note in the Gear VR (came free with it) was an ok experience but my god did the phone get hot, they are pushing the performance of these devices to the limits so it should be expected they get warm, but then there is a point where you should be asking if it was actually thought through, if the phone is overheating then that is a problem and something that should have been seen before now, but if the phone is just generally running hot I would see it as something normal when you are taxing the CPU and GPU to the limits. but if it is running hot to the point of shutting down something is wrong there.
Since this is the phone they used to build Daydream VR (only certified phone) I am sure they tested extensively. This maybe the reason for the low power version of the 821 instead of the higher performance version. The phone actually shutting off I beleive means a defective phone. Unless you just missed all the heat warning I would call Google and get a RMA before your battery goes bad permanently.
Even gear VR overheats it's just the compromise of the mobile versions for now.

What if you didn't use a case, and maybe put a spacer behind the phone so when you close it there is a space behind the phone for it to breathe....and stay cooler? Can't wait to try the headset out when it comes.

I had read that Daydream on the Pixels has an exception to the thermal throttle normally enforced in order to achieve the required 60FPS for the scene, therefore enabling it to push a little harder than most other 3D applications and inevitably getting hotter. As mentioned earlier it was probably all subject to extensive testing by Google and aids in the explanation to the lower clock speeds they have chosen.
I'm fairly confident that Google was confident the heat is acceptable and considering it's the latest and greatest from Qualcomm the only alternative would be some heat pipes and heatsinks sticking out of the phone.
Same deal with the Samsung vr
Got mine, got through the tutorial and it was already very warm.
It is nothing I can picture me using it too much anyway.
I have the Pixel XL with me almost always but I am not bringing the viewer with me all that often.
I've tried just holding the Pixel XL against the VR Headset and leaving the flap down. Seems to keep temperature down a bit.
I was testing it out that way but ended up on a phone call after about 30 minutes of use. (watched about 5 or 6 movie trailers in 4k and 360).
Phone was only warm to the touch. Temperature in house usually kept around 75 degrees.
Anyone else tried this.?
I know these phones are supposed to be waterproof so I would assume airtight also. So why does my G6 get extremely hot just by putting it between armrest and car seat? Not charging, screen turned off and out of direct sunlight.

Putting my phone as described, it would disappear below the seat.
Probably you have butt-heaters in your seats.
Or your phone just heats up to body/rump temp, which is higher than that of your hands and can feel near hot when touched.
Waterproof does NOT mean airtight by any means, also doesn't mean there's a vacuum inside.
That aside, the heat still has to radiate away from the phone. You stick it between stuff, you take away its ability to radiate the heat and it ends up warming up more and more.
-Phone coulf crash and reboot without notice. Under such conditions sometimes part or all of the Dalvik/Art binaries get re-compiled on boot. This will generate heat for a short period.
-Huge amount of junk like cache files will cause almost permanent higher load, more heat and less battery time.
-On another phone i once had a bug on a custom rom causing that the cpu governor was reluctant to downclock or switch off cpu cores. It did happen, but much less frequent, most time all cores were running at highest clock, but with near zero cpu load. I noticed the excessive heat in my pocket outside in winter, before within about 4hrs the battery was drained in standby. Never saw such thing again anytime/anywhere after flashing a different version of the rom.
