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.
Just curius. I tend to use my phone ALOT, just can't put it down, i love it.
But i started to notice my thumbs are feeling like i got burnd on somthing hot. The screen feels very warm and my fingers hurts.
Am i just imaging? Have i just used the phone so much i weard my fingers down, or is im actully getting small burns?
Not the most regular question here. Darn i love this phone to much. With HD2 i had O.R.D . Now i have E.U.D. Extended Using Dissorder) =/
Never happened to me. I doubt it would be getting that hot or the screen would melt. Or the battery would explode.
Im not saying the phone will melt, just that screen feels hot. But guess it's only me then
No it's not only you, i have the same issue. When i use the phone for quite some time the screen gets really hot. Like you said...sometimes it's like your fingertips are on fire! . When this happens i usually stop using it for some time. It cools down pretty quick (half an hour i guess). Other than that...my phone still works perfectly (i've had it since december 2010).
Half hour!!!! Your strong minded =P
Nice to hear im not crazy thou. I guess its a small prize to pay for having the best screen :-D
Hehe...i do have to sit on my hands for that half hour ...
But you're right...it's a small price to pay. Just the other day i saw a HD7 (with LCD)...and i was baffled with the terrible display quality :S.
I'm looking forward to the new Samsung WP7 phone. Rumour: A 4.3inch Super Amoled screen!!
He he, yeah. But i must also wait for what Nokiia have up there sleaves. It´s gona be a intresting christmas =)
Im a bit scared to buy a new Samsung since i been having the call issue and slow internet etc. I just sent it in to Samsung today to get a new radio firmware they havent gone public with yet =D. So there is hope.
In the end, i wonder if its not gone be better to wait untill we find out what the real plans for Xbox on WP7 is heading. Might be that there will be some awsome power phones coming with some hard core graphic cards. Nvidia and MS have been up to somthing i belive, I strongly belive that gaming will get totaly´ly amazing in the future for WP, since there focusing hard to turn the consol to be a entertainment center, leving somme room for a full gaming experience. But i guess, only time will tell.
Have been having the same issue to but it has only been lately on really hot days and out in the sun, but that is the only times I have had the issue
Yup, I've noticed it too.
I don't know whether it's the screen itself or whether it's heat from the internals conducting through the screen.

dude i also feel warm not in screen but back of phone,. When i play 3d games or use 3g apps, it gets warms... When im charging, omg that time it seems like it is cooking... Is it bad samsung build fault or bcoz of flashing omnia 7 with different firmware ???
Phone : Samsung omnia 7 i8700 (t-mobile)
i have this problem when i using a lot my phone but charged too.. (combo)
about the back of the battery cover i think is normal to be hot because battery goes hot and the metal cover leave more feel to user than a plastic cover..
That's okay, friends. It's just the CPU/GPU getting hot when you do things that need power (games e.g.).
You should feel how hot the Samsung Galaxy SII gets at the back when you are playing games (or the EMail client is crashing again and both CPU cores stick at 100% ).
It might get hot while charging too but that's the battery then. Nothing to worry about, just enjoy your phone
sadly i don't have one of these elite-atrix which can stand massive overclocking without at some point reboot because of too much heat.
so i decided to do something against overheating.
what i did was tearing apart the atrix and removing the aluminium part covering the tegra II chip (and no this piece doesnt have any contact to the chip so it doesnt serve as heatspreader).
now i took some spare aftermarket ram cooler and grinded it down to the exact size of the chip.
next step was quite easy: just cut out some part of the inner plastic frame to have some space for the new built "cooler".
last but not least i just put a small drop of thermal paste onto that chip and pressed the new cooler on top. (sidenote: you shouldnt have to glue it. it will keep sticking there because of adhesion)
no i'm going to try wheather this has any effect at all gonna flash some 1.5/1.6 kernel and see if my atrix can handle the speed now
pictures and results follow soon (partly done)
btw any good app to log temps?
Here you go with some pictures (more to come):
Really cool. You are a brave one....
I might have to try it.
Thanks for the info.
Even running at stock speeds the heat management on this phone is horrendous. I actually think the overheating caused my digitizer problems.

Interesting, I hope you took some pictures. (and are willing to share!)
Hahaha, that's epic. Finally a real hardware mod for the atrix, please upload a picture!
Sent from my Atrix
I cant wait to see the pictures! XD
sorry mates, had no pc around and posting the first 10 times via tablet/smartphone is a pain in the ***
So the results are not that overwhelming but i'll surely try to figure out how to optimize all of this.
Results so far at stresstest
Clockspeed ..................................... Before ....................................... After
1000mhz max....................................working........................................ working
1300mhz max .........................reboot after some minutes..................... working
1450mhz max..........................reboot & bootloop soon.....................reboot after some minutes ... sometimes bootloop
as you can see there already is some slight increase of stability with overclocking, but i think that there can be done even more. just got to find a way how to squeeze even more heatsink into that little case without having to cut out any more will try with aluminium tape and also with some leftover copper heatsink soon
Copper should be better and maybe some holes in battery cover.
I hope that you're not going to try water cooling
no but got some copper heatpipes lying around XD
yes some holes in the cover would be better, but i really want to keep the outside stock.
well i also could also varnish some copper-plate into the backcover having contact to the heatsink on the cpu. so there would be a much bigger surface and of course allover masses. but i suppose if you hold this ting in your hand it would be too freaking hot. holding my finger down on that little heatsink while stresstesting can already be painfull. here i'm glad i got that plastic cover in between.
my plans are now to extend the heatsink over msdcard and simcard, since there is some good space left. maybe next days when i'll get home again
Actually copper plate into the backcover is great idea! Don't worry about heat because bigger surface and you still have plastic between heatsink and fingers
I did similar thing long time ago with zx spectrum
well then i need a really thin copper plate wich will not have that good effect on cooling, or i replace some area of the backcover with copper. then there would be heat issue (and aesthetic, too)
Try to find copper foil or easier aluminum foil. Just be careful to avoid electrical short circuit
Are you testing with or without the cover on?
What are you using to conduct the stress test?
I know you want to keep it stock, but an extended battery cover would give you lots of extra room and many have vents. Might even be able to squeeze a fan in there for active cooling!
atm i'm testing with back cover on. having stable oc only with back cover taken off doesnt make any sense since its unusable as daily driver.
i got some aluminium foil at home and some some fine copper plates.i'm sure i'll be able to work something out.
atm I'm using cm 7.2/miui hybrid with faux's 1450ghz 027b5 kernel. slightly undervolted.
mainly stresstesting with "StabilityTest". after about 10 mins of stresstesting i wouldn't get temps over 65°C still tweaking a bit, then i'll give some benchmarks a go and will see if i can get 1.6 ghz kernel running
still looking for some good tool for logging cpu temps or at least showing on screen/status baar. atm got to switch to setcpu and open cpu info tab to get some readouts.
I'm curious to see how 1.45Ghz kernel and tweaked stock rom will do in webtop-mode. hopefully this will be also run stable since webtop-charging also produces some extra heat. we'll see when i get my lapdock back from motorola ^^
extended back cover would be an option for space as long as i dont want to dock it to lapdock oder cardock, which i do multiple times a day. so no option for me.
i have also thought about adding a fan, but when i think about it, it's way to big, makes noise and drains even more juice. so this is a no-go.
if you would want to do extreme overclocking just for benchmarking this would be an option again. but then we would need a kernel with even higher clocks to get something groundbreaking...
so who starts with a LN2-cooled smartphone ?
Lol, fan is going to drain battery really fast. Only for extreme overclocking. Bigger heatsink, some holes or extended battery cover should be enough.
At the end he's going to overclock with liquid azote
Edit: system tuner pro could log data. Try it.
stresstesting @1450 faux kernel 027b5
while connected to a 1.6A charger and static 100% cpu-load i get temps of 86°C with the phone freezing.
got to play with some profiles here and maybe even more uv.
thanks for the tip with system tuner pro, looks promising. now i can get more accurate values and also log and see when the device crashes/reboots/freezes, etc
86°C is too much! Be careful, don't burn your phone

lol Could fry some egg and bacon on it!
be sure that i know its way too hot. i set up some profiles in setcpu and undervoltet a bit more.
i'm trying to peek at even while powercharging 65° but for that i will have to improve the heatsink. atm i still get about 72 with limit of 1200 when over 65
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.
Sent from my LG-LS993 using Tapatalk
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.
