[Q] desire and heat - Anyone else getting hot

Folks. Just upgraded to Telstra stock 2.2 and was curious if the excessive heat when taxing the device was a general 2.2 quirk or if the stock Rom is somehow dodgy.
Noticed this most on angry birds. Played for about 20 minutes the other night on 2.1 without any significant heat. 5 minutes tonight under 2.2 and boy did she heat up.
Anyone else noticed this? Thanks in advance.

i am also facing heat related problem.Mine is unbranded Asia version,while using youtube or any flash video my device get too hot near the charging port or we can say mother board is getting over heat. i think there is some problem with all htc desire bcos this is my second htc desire.I have sold the old one bcos of same reason.
its a shame for htc and they are expecting that desire could be the phone of the year.

I have the same problem with my Telstra Desire, it always heats up when playing games :\. I called HTC but they said anything under 50 degrees Celsius is within reasonable limits.
I don't like burning my hands and face though....

Get a widget off the market and monitor the temps. Mine will range from around 15 - 35 degrees Celsius.

This is not a issue, the desire has a powerful cpu and obviously no fan, when using complex games and apps, the cpu and gpu have to work hard, thus creating more heat, combine that with the high power drain of the task, the battery also heats up, i know it can be worrying but htc have been doing this for a long time, the desire is made to withstand this

I think this is becoming a serious problem with the Desire, mine started to overheat and then one day just started going into a reboot loop. Never rooted or anything like that.
Unit went for repair and was replaced with a new one, unfortunatley the new one has the SLCD screen
Just a quick comparison now that I have owned both AMOLED and SLCD:
AMOLED = Better battery life
SLCD = Sharper text but poor battery life
Both screens unreadble outdoors on a bright day.

The SLCD should have better battery life while browsing, worse while watching darker movies.
Heat:
It's normal. My old Nokia mobile phone (not smartphone) got hand-warm while playing simple games, too. Now, the Desire, is a smartphone with a very powerful CPU and GPU. It's no surprise that this thing heats up. The processor even has a heat spreader. The processor is located near the USB port, so this part will get warm while playing games, navigating or doing long web surfing sessions.
All smartphones, using the latest technology have this issue, because all smartphones use the same technology and get passively cooled.
It's nothing to worry about. You can reduce the heat and increase the battery life by rooting and flashing an undervolted kernel.
PS: The Desire never does get that hot that it will burn your skin. So it will get warm, maybe warmer than your skin temperature, but nothing to get worried about.
PPS: I haven't noticed a difference between 2.1 and 2.2. 2.1 cause temperatures above 40 Degree Celcius sometimes, 2.2 also. Since undervolting I never reached that high temperatures again.

Just to echo what the others said, the Desire gets hot, that in itself is not an issue. It's got a 1Ghz CPU and that needs to dissipate a hell of a lot of heat when under load but it's got nowhere to go except the casing and your hands.
The reboot loop issue is a known problem but this is a flaw with a number of Desire's out there (my first desire had this) and your Desire can get very hot and be fine. If it gets very hot and reboots you've got a problem.

thats a good point, not all cpu's are made the same! my desire gets very hot sometimes but never reboots, some people get lots of reboots when there device gets hot, its the same as overclocking, some people can overclock there cpu to alot higher clockspeeds than others

Mine gets hot after some heavy usage (especially Flash, videos, games etc). Around 40 degrees celsius. Doesn't concern me too much.

Seems to me that I may not have been clear enough in my original post. I realise that heat is normal with the power that's in these devices, and I'm not overly concerned by it.
However, I noticed that there seemed to be more heat running games on 2.2 than 2.1. This is simply an impression and I don't have any empirical data to back it up. Just curious to see if anyone else may have experienced a similar effect.

Does this have anything to do with batch.
My faulty one was HT06 and it was replaced with HT08.
Any thoughts?

I would agree with that, my one seems to be running hotter under 2.2, not only just with games though.

well i dont have 2.2 yet but so far Desire heat is nowhere near to what my old xperia x1 did produce i should be upgrading to 2.2 later on today or tommorow so will post my impresions later

Ouch Ouch its burning

I was just curious to know if someone else's phone is over heating. Yesterday I was watching a boxing match on youtube with 4G on and it reached to a scary 121°. 4 hours later I was playing the nova demo with the screen at 45% brightness, played for like 20 minutes or so and it reached 112°. Just whanted to figure out if this is normal that personallyI think is not, and also if someone else it's experiencing the same issue. Thanks
Edit: Both of times I was indoorsjust in case someone is wondering.

Mine can get much hotter than that but it pretty much hovers around the 120 range when I'm browsing the web.
I also get this message when charging and watching a video. I need to exchange it. Just need to find a Best Buy store that has one in stock.

What do you use to check the temp?

mine gets real hot as well.. I think it has to do with charging while using though.

Woow thats amazing. Im guessing that those temperatures can be harmful to the phone right?
I use system info from the market to check my phone status very useful

It could be that and the stock charge pushed a lot of power in to charge quicker... But my input is that my phone hasnt even gotten very hot at all..

My phone was just laying in shotgun of my car with the car charger plugged in and the display on, then all of a sudden I picked it up and it was hella hot! 120° read SetCPU and I got shook, ripped the battery out and threw the phone in front of an AC but then I got worried that the extremities could possibly warp the board, so now Im thinking Im going to return my phone! In no way can this be good for the phone, I don't see how it can not get affect it when reaching 120, 130, 140 degrees!!! Im worried that in a week, a month, a year from now something will go terribly wrong and I really don't want to risk it, so I'm real close to returning this phone and just waiting for the Nexus!

I am amazed that a phone getting hot after heavy use is such a surprise to everyone. See any fans? see any ventilation? Here you are using a dual core 1.5 GZ processor, what were you expecting, ice water?

Ahh... Set CPU. So you can't really find the temp until you're rooted?
Hmm

Who mentioned anything about heavy usage and overclocking? CPU is 1.2Ghz stock buddy and I wasn't doing anything on my phone at the time it overheated...I have a Droid Incredible 2, and I run its CPU OC to 2.035Ghz and its never once gone over 105 degrees, so before you go getting all amazed, get your facts straight!

I have noticed this too.
With the phone simply in my pocket, my leg would feel warm. I could grab the phone and the phone would feel quite hot. Not so hot that it would burn my ear, but warm enough that it would feel like there's some kind of problem. Usually, heat = battery getting drained. When I check to see if there's anything running, there's nothing...
Right now, have been listening to Spotify for over 2 hours, and it's cold as ambient temperature. Will try installing some monitoring program and report if I notice more heat issues. I know the Evo3D used to get "burns my ear" hot when using it as GPS while connected to the car charger. My guess was that if the screen is on, and there's power going to it, it'd always get hot. Maybe it wasn't supposed to and that was just my assumption. However, same thing happens to this one; watching netflix, or playing a game, or anything demanding, and if I'm plugged, it will get really hot, really fast. If not connected, it won't get as hot, but "normally" hot nonetheless.

That you know of, did they ever fix the issue on the Evo3D?

Let me put it another way. I don't see any process or feature that will cool down the phone when in moderate to heavy use. I expect it to get hot. I have always thought, how are they going to disperse the heat?

Mine got hot on day 1 from youtube and general setup but after a full nights charge it has been great for 2 full days, no heating up or anything weird.
But man did it get hot!
Edit: I turned off gps the night this happened. I have been using my phone alot and have not experienced this again.

You need a dose of Penicillin and Cortizone. The burning sensations should clear up. In the mean time, stay away from strange phones and turn off the vibration loop - LOL
Sorry, but I've done quite a bit with my phone (videos, NetFlix, etc...) and it doesn't get warm enough to burn.

An Intel CPU (i7, for example) can run at 200 degrees Fahreneheit. In fact, the roof is about 100 degrees Celsius. To protect the CPU, there are heatsinks, fans, water cooling, etc. Video cards can also go up to 70 degrees celsius before showing artifacts; some can do much better.
We're commenting a heat that is not nearly that much for a phone. IF the SOC gets to 100 degrees celsius, that's one thing; 100 degrees fahrenheit...that is the temperature in many places around here.
These SOC don't need such fans, heatsinks, etc, because they're not supposed to reach temps of 200 degrees. They should be self contained.
On my Evo3D, which I passed on to my father, I could smell like something was burning. It wasn't, but it smelled like if it were, around the battery. Yeah, it still gets hot when in use, and specially if connected.
I believe there's also comments that on all new phones, the first few charges, while the battery adapts, the phone may be hot. Of course it had been over 2 months on my Evo3D and it still gets hot.
The E4gT is doing better today, but I haven't thrown any video/games at it yet; nor has it been in my pocket.
I'd say give it a couple days. I know I've reported my own concern, and I'll be checking it to make sure the "hotness" is within reasonable limits.

Battery overheating a lot (CDMA version)

My battery seem to overheat alot,its even uncomfortable to hold up to my face sometimes. Is this normal? The back gets very hot two.

My GN seems to get ridiculously hot pretty often for NO reason. Up around the camera is usually where the heat is focused.

Yup around the camera is where it happens to me too. It usually only happens when I stream Google Music or Slacker

Mines gets hot there too while im just browsing
Sent from my Galaxy Nexus using Tapatalk

Just browsing? That can't be good. Are you rooted? If so, how high do you got your phone over clocked? Maybe you also may have too many processes opened

Most LTE devices heat up under browsing. Its not the battery that gets hot.
Also, I cannot think of a single phone I have had on Verizon that did not get warm during extended calls.

mine heats up a lot also. After talking or browsing for a while it does get warm.

What's your LTE signal strength? If you only have a bar or so, it's been my experience that the phone will heat up trying to keep the connection. At work, I've had to turn off LTE in order to keep the phone cool and save the battery.

Two reasons why that area gets hot:
1) LTE antenna
2) SoC (CPU/GPU)
Both are in the top of the phone, away from the battery. If you're taxing either the CPU or your data connection, it will heat up. As long as your battery isn't getting hot (heat increases the decay rate in lithium-based batteries) you're fine. Silicon can take a lot more heat than your hand can without sustaining damage.

I might need to get a case for my phone and screen protector

I have Battery Monitor Widget installed, and it has been enlightening. Here are my observations, using the charger that came with the phone:
The following behaviors happen on the stock ROM (using the Franco Kernel), CM9, and BlackIce:
If I am on WiFi and charging, it charges quickly, and the battery temperature reported by the app stays within the default limit (45C).
If I am on 3G, and on the charger (whether using the phone for anything or not!), the app shows the battery temp rising quickly, the charge rate drops to zero. The battery is no more than 35C based on my best guess when touching it, HOWEVER the area around the camera is very warm I (where the phone radios are). If I unplug the charger for a minute or two, the temp drops, and plugging back in will start charging again, for a short time, until it heats up again.
Underclocking seems to help this issue, as I discovered, a short while ago (playing with the BlackIce ROM, today), and I will update, once I play with it some more. This said, my suspicion is that the processor heating up is the issue, and NOT the battery, though Battery Monitor Widget claims the battery is overheating. Throttling the processor should help. Underclocking and undervolting BOTH, should help even more, I bet.

It's normal for LTE devices to warm up during extended/heavy use. It's not bad for the device unless you hear a pop or smell burning.
Heat shields FTW!

It IS, however, a problem, if your device is getting warm enough that it ceases charging itself, which has been my experience.
Imagine this scenario: Your phone is below 15% charge, and you plug it in, hoping to be able to get through the day. It charges for five or maybe ten minutes, then you see the battery level start to DROP, rather than rise. (and forget charging, in the car, while you use navigation, or play music, of both) This is what is happening with mine.
The Battery Monitor Widget says that the battery is overheating, when, in fact this seems to be processor and radio related, since it only happens on 3G (and presumably LTE, though I haven't verified it) and only when allowed to operate at a normal clock speed on the CPU--forget overclocking, that worsens the issue, too, and all of this happens, even when the device is sitting idle.
This happened to me on both the FD01 and FD02 radios (I didn't use FC12 long enough matter), so I suspect that we can rule out the radio.
Reiterating, this happens on the stock ROM (with Franco Kernel), and both CM9 and BlackIce, with their respective kernels that they are packaged with. This begs the question of whether it is a problem with the process that monitors the battery charging using up more CPU than it seems necessary for such a mundane task,
Everything else on this phone works wonderfully, so I don't believe that I have a bad device. I should not have to UNDERCLOCK such a high tech device, so that i can charge it effectively when it is sitting idle.
Any thoughts on this? Anyone else have these issues?

[Q] Overheating on charge.

I charge my DHD every night over night, to make sure it has a full charge at the start of everyday. I've had my DHD for 16 months and I have had no problems with it ever. I've run many ROMS and kernels and its been rooted since the first week I got it. However it now overheats when I put it on charge almost every night.
I plug it in and the temperature will steadily rise from about 29 - 32C (which is what it runs at throughout the day) to over 40C, I've never seen what it actually reaches because since its over night I haven't monitored it that much. The highest I've seen it is 47C. After the first few occurrences of this I set a profile in setcpu to set the phone to 800Mhz when temperatures go over 38C. However this was to no avail. I then set it to underclock all the way down to 230Mhz when it goes over just 35C. But yet it still overheats when on charge so I don't think it has anything to do with my CPU? I changed kernels too but it still didn't help. The only reason this really annoys me is when it does over heat (lets say 1 in every 3 nights) I wake up and its just boot looping over and over until I do a battery pull. Which means my alarm hasn't been going off so I've had to dig out the old G1 the past two weeks just for it to act as an emergency alarm in case the DHD overheats.
I'm not sure what my problem is here, any insight?

Might want to try replacing the battery. Is it a third party bettery, those cheap "Gold 2000ma" batteries are notorious for overheating and being a bit rubbish. The other thing that might have happened is there is a short in the charging circuit which is causing the overheating.
I would say it's a 80% chance of it being a hardware problem. Try a different ROM if you are unsure.

If you have an o/c tool like no frills cpu control or anything like that, then that could be your issue too. Running high on cpu can cause overheat even when the phone is in sleep mode.

Thanks for the replies.
I have my cpu overclocked during the day but I have a profile in setcpu which underclocks it to 230Mhz when the phone goes over 35C. I've seen this in affect and the cpu does downclock as expected yet my phone is still overheating.
I am using the stock HTC battery still and have had no issues with it before. I will try another ROM/kernel combo and see if it that resolves my issue just in case. Otherwise I might have to S-ON my phone again, put it back to stock and send it to HTC...

I had this same problem it was the setcpu app or no frills create another profile and put the setting on charging and turn setting down or add profile when screens off 122-245 set priorities to high hope this helps

If it's not a software issue, your battery might be faulty and you should switch it as soon as you can.

My Desire HD is fitted withe the original battery and its also getting hot during charging.

I've been monitoring my battery with 'Battery Monitor Widget' from the market, the recordings show that throughout the day my battery fluctuates between 20 - 30C depending on my usage. As soon as I plug it in however the battery immediately starts creeping up from low 30's to around 47C, this is where the monitoring stopped and has a huge gap until morning when I boot my phone again.
I applied a new profile in setcpu as suggested for charging instead of temperature and tested again last night, I set the charging profile to 230/384 min/max. The monitoring from last night shows the phone reached 40C by the time it'd charged to 100% and steadily started to cool back towards 30C, my phone was on when I woke up and functional so hopefully this is a temporary fix until I eventually have to get a new battery because I'm pretty certain its a hardware fault.
How long is the standard warranty for a Desire HD? If its 1 year then I'm out of luck and will have to buy a replacement...

Did you ever try uninstalling the setcpu app or any cpu controller and try that.. another thing what Rom are you using . Did you try wiping the battery stats in recovery

Worth a try, Im using Virtuous Quattro RC3 at the moment. Although the ROM development seems to have died so I might try the other stock ICS ROM I see floating around for the DHD.
I've been told to dump setcpu about 948 times before due to performance issues it supposedly brings or other faults and I just cant tear myself away from it, I've had the widget on my home screen in the same place set up the same way for about 3 years across 2 different phones and about 20 different ROM's, I just cant seem to force myself to get rid of it.
Wiping my battery stats seems like a good idea and I'll make sure to do that tomorrow morning when my phone will be fully charged. I'll also change my ROM later this week and if I'm still getting issues I will TRY to ditch setcpu for a while. If I still have issues then I will have narrowed it down to some sort of hardware fault.

nexus heat issues?

does anyone else is nexus get really hot when surfing the internet or doing anything else. I've only been using the phone for 15 minutes and it's already dropped 10 percent. idk its up to about 118 degrees
is this pretty common with this phone?

Clock speed
Usage
Screen brightness
Those affect how your gets.
Are u an aggressive user and clocked it up high and always have high brightness.

No only 15% brightness no over clock. New phone just got it today just seems to heat up asap...and gets over 110 degrees easily. The of course causes major battery drain. Prob normal for this phone just never experienced heat like this before

Isn't the processor on the Gnex designed to do a panic restart when it reaches 110 C's ? :/ yes its a big issue i've noticed that the phone doesn't get that hot when using stock Rom weird...

I don't get over 110 and I'm OCed to 1.3gHz, auto brightness on.

The only time mine gets abnormally hot is during a phone call. Im even underclocked and it still does.

getting hot in a smart phone this powerful is normal. I had the S3 for week, that sucker gets hot!

I agree with OP. Mine gets noticeably warm when scrolling through large non-mobile web sites. It cool when scrolling through apps like tapatalk, market, reader apps. It must be something to do with browser engine

Mine gets quite warm as well. Especially with games like gta 3 and Final Fantasy 3.

please don't forget that you're holding a device with a dual core CPU, clocked at 1200 MHz, without fan, water-cooling or anything. ever tried touching a computer-cpu?
(don't do that, lol)

Mine can easily get to 110 degrees. It definitely has a heat issue. My Razr Maxx can get warm too, but not hot like this GNex. It hurts to palm sometimes !
LTE / Camera / Data stuff . / Charging all contributes to this.
Thank god it has removable battery, since battery life will be significantly dampened by heat.

Mine gets hot since Jelly Bean... Maybe "project butter" is intended to melt our phones like butter

remember, battery temp and cpu temp are two completely different things. cpu temp will get lowered automagically in the gnex when it reaches a certain point(heat throttling is enabled in the gnex, unless you disable it), and it will shut down the cpu when you reach 110C, not 110F, that is a safety feature. 110C is 230F btw.
