heat from bottom of phone - 44 degree temp

i havebeen using my phone for the last couple of hours to listen to music and do a bit of surfing whilst bored at work ... the temp has got upto 44 degree's , its not plugged in charging .... is this normal ??
the heat seems to come from the bottom of the phone .....
ive had some hot phones but this is ridiculous - htc really need to sort this before our phones ... excuse the pun burn out !
what temps have your phones got to ?? is 44 degree's ok or is it too high
i dont want to turn the phone screen off every time i use it for a while just to cool the damn thing down.

What phone are you using. I have n HD7 that gets really hot. I mean really if it wasn't for the development on HTC devices no one would be buying them. The build quality is poor from the processor to the display to the housing. That's why Samsung is a trusted manufacturer but lacks development its truly their only flaw.

dude he is clearly using a htc sensation i mean he is in the sensation forum from your response do you even have a sensation and yes its normal for awhile but it stops eventually

I use" Battery Indicator " app and i chill usually at 32-34C.. just played one level of plants vs zombies and im at 42C kinda ridic if u ask me i usually put it down at 41C or beyond to let it cool down

Yep using sensation - the heat is crazy .... ill try the app
how long do i have to put up with this heat before it settles ???
the temp doesnt seem to come from the battery as it radiates at the bottom
i cant believe htc released a phone which causes so much heat - will a firmware release sort it ?? i wonder

BUt relax i think it's normal, is a dual core phone, my Galaxy SII have the same problem but arround the camera, and the screen gets really hot to...
I can't say what of the two gets hot.

Cool it man I'm using the xda app for android and it doesn't exactly tell you where you are unless you navigate there yourself. Also don't ask me why and how I got here I just saw an interesting topic an decided to add my 2 sense. Had a sensation and it crapped out on me within 3 hours. Got a second one same thing after 3 days it crapped out to.
Sent from my HD2 using XDA App

well today mine got up to 44 but that was my fault. i always take the case off when charging it and i forgot to do it. also i was using it during this.
the case reduces heat dissipation. as soon as took off the case it went down to 38.
so i recommend that if you have a case on your phone and you see or feel that is getting too hot, take off the case.

I wouldn't want to say it's normal however I've had at least 3 sensations that were hitting around 43 to 45deg C just on battery while using Google Maps or browsing the web. The reps (all three working at the time) in the store found it strange that the phone was getting so hot just to the touch.

May have to underclock our devices like the iPhone. shouldn't be much of a difference considering it has a dual core processor right?

The most important isnt the Frequency, the most important is the voltage in the processor...
On SGSII, you have practically the same voltage at 1.2Ghz than 1Ghz or 800Mhz...
So i think is the same on Sensation... lower voltages, or you never get decent temperatures.

Am I being to simple here or is it just the fact so much tech is in the handsets now that it will obviously get hot? I would of thought this is the norm for phones nowadays and without sticking a fan on the back there is nothing that can be done?
Can we compare this to a PC? What temp do processors run at on a PC, and is there a limit before they lag or fail?

You cannot compare a smartphone to a PC, due the pc have an active cooling, and an smartphone have a passive one...
So, the smartphone will get more hot than a PC.
This temps are good, but think this components are more delicated than a pc, so the temperature isn't good for her life.

Played 15min of asphalt hd and the phone got very hot. I took off the back cover off to investigate and noticed the microsd is located at the bottom of the phone. The microsd was untouchable. Hope the device heat will not damage it.

All HTC devices have inbuilt thermal protection. If the phone gets too hot it will shutdown and/or reboot.

Mine got up to 52C while outside using the GPS Saturday.

i think the highest mine has got is around 115deg. (around 46C). this is rediculous i think since it only happens when i play a game for like 20 min..browsing the web reaches around 107 sometimes. but im past my 2 week remorse period so i cant return/exchange the phone at t-mobile, dont know what to do since some ppl say this is normal for being a dual core and wut not, but then not everyone has these overheating issues

Overheating screen

Hello, I got a new HTC sensation a few days ago and I've noticed an odd problem with my screen. I've heard of the overheating battery, but for me that isn't the problem. Oddly enough the only thing that overheats is the actual touchscreen, mainly the bottom portion with the haptic feedback buttons. The screen only overheats if the phone is in use for a period of time, but if it's sleeping then it stays cool. I just wanted to know if this is common and if I should be concerned with it.

Phew, glad I'm not the only one. I'm just worried if it might damage the circuitry inside since the screen can get pretty hot.

I got the sensation yesterday. Was dissapointed at how fast it heats up there. but I have to say, compared to my g1 and n1 it cools down reaaallyyy fast!

The dual core cpu is behind there, thats why

For me the issue of screen was never there, it only appeared yesterday (its been more than a month since i bought my sensation). Yesterday i was playing a game and the battery was at 8 % so i plugged the charger and kept playing for another 15 minutes. When i exited the game and then after 5 minutes i checked i found that screen's bottom portion was heated up and not working properly. Launching other applications and doing weird stuff. I checked the temperature and it was at 40, i let it cool down and when temperature reached 37, the screen has become less hot and it started working properly and is fine since then.
The only thing that i m worried abt is if that heating might have caused some permanent damage to screen.

Have any of you owned an android device before? Pretty much all of the ones i have had heat up ESPECIALLY When connected to wifi,charging and playing games.~Only difference is this one has more than TWICE THE POWER of any of my old devices, i would worry if it didnt get hot.Just my 2 cents

I have owned a fair few phones and had every android t-mobiles released in my hand for at least 48 hours and non show heat problems like some of these devices.. i think when the undervolting is done and a scalling the problem is decreased.. But my first sensation died while on charge and was stupidly hot round the touch buttons.. My second sensation hardly gets hot but is now awaiting UPS to take it in for a power button repair..
The architecture of the chip and the expected heat output should not cause the other components of the phone or the chip die to critically fail.. These are the first generation dual core cpu's and I am sure they will learn by the mistakes made with having the ariel's etc in the wrong places.. shame we have to be guinea pigs.. Will be good to see if they have took notice and the XE doesnt suffer some of the issues..
the back cover issue has certainly beeen attempted to be address'd they have 3 revisions of it out so far...

[Q] Sensation heating up - but not the battery!

A few days ago I noticed my Sensation (stock ROM, Anker battery) heating up whenever I use the phone (for browsing, SMS, games, etc).
It's the lower part of the phone, especially the front where the touch buttons are. Sometimes it gets very hot, though never sufficiently hot to feel like my hand is burning.
I've checked the battery manually and it is cold, so it's not the battery. The screen is normal temperature also.
Anyone else notice something similar? Anyone know of possible cause?

Yeap I have the same trouble... Mainly it's get hot after 15 20 min countinues use...
Any cure yet...or any suggestions plz

I really dont think it can be resolved with undervolting etc on any kernel, pretty sure its a hardware design flaw.. my first sensation died on charge over night as stock... I had reported it about getting hot while sitting in my pocket.. the wonderful HTC rep said uninstall all apps.. the day it died it was stock and had no installed apps.. prior to that, looking at the logcat seemed to be pretty uneventful... top command showed nothing unusual cpu wise since getting my new main board it got hot once... when i ran cf bench with mikes rev rom... apart from that its perfect.
unless.... the new dual core kernels are stopping a part of the cpu die getting hot due to both cores being implemented correctly... I could go back to stock and see but thats not fun

CPU + Radio + wifi + GPS = heat. The more you use the faster it heats up and hotter it gets. The CPU is in the front bottom.
The Anker has a bogus temp sensor, so the phone won't report battery temp correctly.

Mine used to do this followed by rapid battery drain but ever since it went for a swim (and spent a week in a bowl of rice) it stays cool and battery life has increased tremendously!

Heat
I have the extact same problem, running Android Revolution 3.1.1. I currently have the Anker battery in but I will be changing back to the OEM tonight to do some stress test and check the temp.
I'll report back.

My quad core PC can, CPU temp increased by 6C to 42C when the fan died over the summer during a mini heatwave, which I thought was pretty impressive
Sensation is currently running at 43C having been charging and using wifi at max range.

haha imagine a first gen p4 running without a heatsink and fan, fried eggs anyone?
but on a more serious note they had to replace the main board on mine.... so even if this is is normal.. the phone should never fail due to this... and i know intel have had some issues with the architecture over the years and recalled some cpu's that melt... ya never know

Overheating
So I put my OEM battery back in my Sensation last night and I was still noticing the bottom of the screen get hot to the touch.
I checked the battery temp and it was 39.1c this felt hot in my hand and all I doing was browsing the web on 3G. I have emailed HTC support to see if this is normal but I have a feeling it maybe judging by all the posts on various forums about the sensation overheating.
I have also notice the same issue this morning whilst sending a long sms with not data connected the battery temp was reported 36.8c.
Should I be concerned about this?
Thanks
Nik

It is normal.
But every machine degrades coz of heat over a period of time.
Changing ROM can helps, I can feel the temperature difference.
Custom ROMs really helps, but you still get hot phone if you play your game over half an hour. I don't believe someone can play a game over 45 minutes, the battery could die by then.
Oh, dun let the battery completely die tough.

Thanks for the reply, it sets my mind at ease a bit.
I post the reply from HTC if I get one.

Guys you're not going to believe this (regarding the power button issue)

So I finally opened up my phone as I was sick of the power button not functioning as it should (sometime one click recognized as multiple clicks, etc) so I opened up the phone, pulled out the tab covering the button and discovered whats used as a switch for the phone. To my amazement, all it is a concaved metal circle piece which makes contact with two metal plates (making a full connection to be registered as a click when this concave piece is pressed down). Obviously, if this very flimsy metallic circle piece wears out (which I assume is very quickly) it will cause an issue for your button.What's worse is that its not even secured tightly to the phone, All that is used to secure it to the phone is the pressure of that piece of plastic tab everyone is accustomed of seeing. i'm furious to discover this about the build quality of htc phone and will double think the next time I make the purchase.
This should help debunk some of the theories that its from a software issue rather than hardware issue.
Edit: uploaded the photo, the white circular thing is the metal piece and the black dot is the thing sticking out, the yellow piece attached to the black dot is the piece of plastic sticking on to the concave

Nice finding. Thanks for this info. You have the guts to do that & void your warranty??

Enviado desde mi HTC Sensation XE with Beats Audio usando Tapatalk

ya warranty is not gonna happen, bought a refurbished unit from a seller on ebay who lives in the states (i'm in canada). I did clean out the contacts a bit and Mcgivered the button a bit and my current observation is that at least its still usable. Honestly though, a design like this where one of the most important button on the phone is governed by a thin metal flake is just ridiculous. If you've seen it in person, you would be surprised that the phone lasted longer than a week.

That's just plain sad. This is my first HTC device and all the hype about build quality.... I'm personally never purchasing another HTC device, not until maybe they come out with something jaw dropping.. Between the power button issue which gotten worse over the past 2 weeks, dust under the screen, touchscreen issues, I'm done. Getting my warranty exchange Monday, selling it, ordering the GS...
Thanks for the find and info

If you still believe it is a hardware issue, then someone PLEASE explain to me why you can install the InsertCoin ROM on the SAME exact hardware where the issue IS currently present, and then suddenly it will magically disappear?
While you're at it, you might as well explain why this issue wasn't present in some of the earliest stock builds.
Now I'm no developer, but I believe there is a very very small detail that was changed in one of the firmware updates, relating to how the device registers the power button click, that is the root of the issue.

i've tested it out throughly. Basically, when the metal flake doesn't bounce back up (or comes up slowly) after its pressed, the phone think it's being pressed multiple times (screens rapidly turning on and off). Obviously, developers can code it in their software to only recognize one press followed by a delay in ms before another press could be recognized, that's probably how your new firmwares fixed the problem. Otherwise, as these metal flakes wear out, this problem will sure start to occure more freqently.

I've heard that the issue emerged with the 2.3.4 firmware, recently I unrooted, reversed S-Off and all that to get it ready for my warranty exchange, and of course original RUU brought me back to 2.3.3.. While I never had a problem at the start, even with CM, when I reversed 2 days ago, the Power button issue emerged, so my take is its hardware, my opinion but I could be wrong. Giving how stupid the design is, I'm not surprised if it is.. I mean really, The effin back cover has to make proper ground contact for the touchscreen, of course its going to get worn out eventually, one of many issues that piss me off with this phone.

There is nothing wrong with the concave metal plate.. its called a tact switch and its been used in many digital electronics..
And by the way, it will not wear out that easily.. you can google about it if your in doubt..

Hey mumos, the thing is I expected to see a tact switch design with everything built in place, not just a piece of the switch lying on top of the contact point, when putting the "button" back in place, I also noticed that if its even slightly misaligned (it's not even sitting in a hole or anything, it just lies ontop of it), button presses become messed up, this could be the cause of the problem for some users too. from normal usage, the switch might've simply moved a bit causing problem to the button prese sensitivity.

Mine gets hot too. It happens during a call, using GPS, and playing graphically intensive games. I think the unibody design has some part in causing the heat issues.

My phone gets a little hot and I always use my left hand to talk -- is there something about holding the phone in the left hand?

Well, oddly might be, I think there could be a little signal death grip happening.
I know I can choke out my WiFi using phone in left hand an cause it to warm up.
Though it might not be the issue here, just an out there idea and thought of mine.
Other oddity I have noticed, every day about 2pm until 5ish, it runs way hotter.
I have written that off as poor signal due to schools letting out and sudden increase of bandwidth Usage by younger users.
