How hot does your phones get while gaming? I've been playing pocket legends on mdj froyo matted and have gotten up to 107 degrees Fahrenheit. I'm not to sure about batteries but I'm pretty sure that can't be good for it. I'm running mdj s6.1 with set CPU set on smartass and 998,mhz.
If it feels hot, it is too hot imo.
I'd rather stop playing my game for a few minutes than fry my phone forever.
Just look at all the 'My Phone Got Hot and Now It Won't Boot' threads
Sometimes, especially in Android, cpu usage will spike to 100%, if left like this, it can fry your cpu
It seems the processor in the HD2 is pretty heat sensitive compared to some other devices
I don't overclock, in fact I find that my phone runs fine slightly underclocked, and it also saves battery life.
If your battery is already hot, and you get a cpu usage spike, could possibly spell disaster
Couldn't tell an exact temp that's too hot, but I would say absolutely err on the side of caution.
ive got upto 47.3C(117F) on pocket legends , runnin at 1.2ghz , didnt give a damn tho
I have a SetCPU profile to throttle the CPU once it hits 40c... I've never had it throttle yet !

Only played 'Gem Miner', but thats not exactly intensive.
Would 'Angry Birds' constitute as intensive, or shall I try something else ?
ive noticed u get about a +5C "bonus" under load when ur on a charger , must be cuz of the pwm circuits have alot of extra work to do

No, I don't think so. I never get that kind of heat when playing angry birds. I think it has to be something 3D to cause that much processor consumption.
Anyone else notice their G2 runs super hot in general? My friend with a Desire Z is able to daily use 1.4GHz...I have to set mine to on demand between 245 and 998 for it not to hit 38C+.
On top of that, my G2 gets about 40C when I'm charging which is certainly quite hot! Running Virtuous 0.7.2 w/pershoot, but it does this on Cyanogen and evil kernel as well.
Does anyone know of any disassembly shots/videos? I'm thinking I might take everything apart and re-thermal paste everything...
Thanks!

Eh... 1st of all... you're going to put thermal paste on the battery? The temperature reading for the g2 is the temperature of the battery.
2nd: I've never heard of a phone that had a heatsink on its cpu. So I don't think you'd even have a place to put thermal paste.
40c is totally fine btw.

Not on the battery! Although, that's an interesting idea...use the dry thermal pads between the battery and the door. I'm just checking if everything is getting overly hot compared to some of your other devices. Thought it may be the charging circuit having issues or something...or bad battery.
40C is fine though? At what temp do most of you have set for CPU throttling in SetCPU then? I have mine throttle to lowest when it hits that temp.

40C does sound pretty warm to me even if its while the phone is charging. I am OC'd to 1.4ghz and even when using the phone while charging, I hardly ever go over 37C.
My on-demand is set to 368/1497 and when temp>38C 245/768, although that profile never really comes into play as my temperature rarely gets that hot. Have you checked your running applications to see if there is something eating system resources? Reason I say that is because the only time my phone gets noticeably 'hotter' is after I have been playing Angry Birds for say 20+ minutes.
I wonder if its due to Variable charging currents/rates. I've noticed this is particularly problematic when i charge from say...15% battery. And yeah, Angry Birds for 20+ mins = toasty!

Hmmm, that seems a bit warmer than the norm. The thermal pad idea was a good thought though. But I'd suspect some modding to be done for it to work.
There's a very detailed teardown at http://tjworld.net/blog/htc-desire-z-tear-down
This is weird. I know a lot of users were complaining of heating issues with their SG2's. I can't complain with the current S2 I have on me. The temps never exceed to that extent where it becomes unbearable to touch, and the temps are usually maintained between 29 and 34 degrees Celsius. I heard from a couple of sources that the Blue motherboard fitted into the S2 has a temperature regulation sensor whereas the Green motherboard does not and many complain. whats stranger is that my quadrant benchmark scores never exceed 3400 (on the 2.3.5 firmware) and its really starting to becoming puzzling. Do I have a hardware defect? or is it something coming in the way from preventing me seeing the full potential of my S2?
A quadrant score of 3400 is typical for a stock SGS2.
lol, I forgot I was running a stock version. i guess those users posting up scores greater than 3700 have rooted their devices with some napthalene kernel, thanks for clearing this up for me. I guess im still a noob. is 34 degrees celsius normal?
^^ "napthalene" ?
Sent from my GT-I9100 using Tapatalk
isn't that the name of the kernel most folks are using? :confused
lol
It is just people aren't used to phones getting warm when they are using an app like a game. They then panic and think their phone is going to die and post about the phone over heating or getting too hot. If you can hold your fingers on it continuously that is warm not hot. Hot is like fresh cup of black coffee which is too hot to hold.

Yeah, and most users also overclock their SGS2. Mine for example does about 3400 when stock, but when overclocked (simple when you have root), will bring it to 3700 and above. I've hit close to 4000 in the past as well.
WIth regards to the temperature, that is the temperature of the battery. 34ºC is normal. It can go higher during charging (I've reached 44ºC), but I recommend not charging and playing a CPU/GPU intensive game at the same time as you would have two heat sources that the phone will have to deal with.
Hi.
Question for Mahdi ROM users on the LG G2:
Coming from this thread, I'd like to know how Mahdi ROM's temperature is when you do intensive tasks, like playing games, running benchmarks etc. Does the device get hot? If possible, tell the temperature, what you were running, for how long, did the screen remain on etc.
Thanks.

Anytime you run an intensive game or the like your phone will get warm, no matter what phone it is. Benchmarks get warm too, however I find those to be useless.
It isnt useless, he's collecting informations about the black lines from a few roms...at least be happy that we have such guy on our G2 section, who is willing to help out as much as he can..

Hot as in "it shouldn't be at this temperature at all while doing what it's doing".
So that means 39°C tops. That's a bit above human normal body temperature. Not bad.
If I remember well, playing Plants vs Zombies 2 gave me 47°C tops in GSAM Battery Monitor, without ever rebooting.
Thanks.
Compass.
yeah max I had was 50°C, but not very long.
I guess it can shoot up higher, but for usually when doing intensive stuff, its about 39. Not to bad.
was one build it was 42 also in rest. That wasn't to long though. pretty cool, new build and fixed haha
@Compass Linux - my device gets extremely hot on any aosp rom even on normal usage, like web browsing, texting, checking emails and reading certain articles on the web, the cpu temp ranges from 50*C-60*C at times even 70*C and it gets throttled down as i set my tmep trottle at 70*C.
battery temps range between 27*C to 43*C which is NOT normal so im no longer on any aosp roms. it scares me as for lithium batteries temps above 35*C is bad for its life. also none of these temps are good for the phone so now im on pardus hd 7.1 and my cpu temps are within the rage of 35-50*C and battery temps from 32-35 under the tasks which i mentioned earlier.

cpu will happily run ~75c without throttling, max temp is 92C at which point it will turn off.

wtf ! thats so strange !!!!!!! thats just too high for me man. i always set throttle to 70. at times even at 58*C when the ambient temps are high in my locality. anything above 80*C is bad for any processor.

If it was bad for the CPU why would it come from the factory to start throttling at 75?
I think you're mixing your views of desktop CPUs on to SOCs.
SOC (system on a chip) are crested to be passively cooled.
For this phone 30~50 idle/light tasks and unto 75c underload is perfectly normal and safe.
Sent from my LG-D802 using XDA Free mobile app
yeah that seems about right according to so specifications
Stuck my phone in the freezer for a few minutes, took it out, and ran the stability test in AnTuTu which plots the temperature and a benchmark score. Looks like it starts right around 34 degrees (93 Fahrenheit), which really isn't that warm at all. You could get that just browsing around and holding it in your hand.
My cpu temp is normally in the 40's and 50's while browsing.
Have you tried turning the thermal daemon mitigation and high temperature property off in the hidden menu and see if this throttling happen? Will be interesting to know if the hidden menu selection works.

It does work. you can just open an app like setcpu and you'll see that it rarely peaks without disabling throttling. Just be careful as it does open you up to potential hardware failures and shorter life of the device. I only keep phones for around 6 months so I don't care but I'm not a normal usage case.

Wouldn't the hardware still have a thermal cut off point where it will just shut down the phone if it gets too hot? It's to my understanding that this hardware shut off point is different than the software thermal throttling. If anything, I think it will just make your device get too hot for comfort than do any real hardware damage to it.
I'm just throwing an educated guess out there though, I honestly have no real proof one way or the other.

Yes eventually it'll hit tjunction and shut down. This isn't even a safe shut down though. It is basically an emergency kill switch. It's like yanking the cord out of the wall on a desktop. Running at higher temps also shortens the life of the silicone. Much the same effect that overclocking has on a normal PC.

If it gets hot, it will do damage. It can fry the GPU before it even gets to shutdown point. The XBOX 360 for example had the RROD where the constant heat made the solder joints fail (I know the 360 is different but the heat point stands)

The 34 in this case is temp or battery, not SoC. The SoC is probably hit 75 Celcius and that's why CPU throttles. Try HWBot bench instead, it shows not battery but CPU temp. You will see that CPU immediately hits 75°

Afaik they shut down itself if battery hits 60°C or CPU burns to smthn like 105C

Why does the snapdragon get so hot. I don't understand what's the point of a fast chip in these phones if they can't run on there maximum lol.... Maybe that's why Intel is gonna take over qualcom one day.

It runs hotter because its having to produce all the pixels for the QHD. The same chip in other 1080 phones doesn't run as hot. At times doing normal things like browsing and Facebook etc my phone has throttled down to 1.4Ghz max and the CPU temp is up at 65-70deg C. That's pretty hot.

Its not the only phone. And mine never throttles that low doing normal tasks. It doesn't even throttle at all. However, when playing games or running demanding apps it does throttle.
Also, its not the only phone that runs this hot. All other phones will get hot and throttle just as much when running equally demanding stuff.
So the question was, what's the point of super fast chips when they are going to throttle themselves so fast?

I'd recommend that you do a bit of testing,run some apps for 5-10 min then open up a CPU frequency app. The frequency will be be at a low maximum and the temp high. The GPU also throttles, open an app like Faux clock after running some apps and the max GPU value has decreased. Without a doubt the extra pixels are causing this as the SOC is having to work harder to produce them. Its simple physics.B
But anyway, its a specs game. People want faster and better so that's why the SOCs get faster and faster even if they're throttling.

The soc is working harder, but like I just said the how soc is still hot even on other phones man.
Run the dead trigger on the s5 and the g3. They both most likely throttle down to the same limit while the fps on the G3 might be a little lower due to the resolution.
But like I just said, what's the point when the damn thing will burn. There is no point in 2.5ghz when your phone can't run at that frequency more than 5 seconds lol.
I remember when I used to run my Galaxy S One full speed. Not one but of throttling. These CPUs have not gotten any more efficient thermal wise.

Yeah, I agree there's not much point in having a super fast chip when it throttles so much. Again, people want bigger faster and better and most users wont even know about thermal throtlling.It does seem to be bad on the G3 though. I think I saw another thread that said LG don't use a proper thermal pad also. Don't know about that but to run a 1080 phone with the same chip as a 2k phone then you'll have thermal and performance issues on the 2k Vs the 1080.

The 801 is more than capable of driving a QHD phone. The 800 series are basically created to support up to 4k. And how will give the same performance as a 800 while on QHD. Its not even close to being a big deal. And yeah I saw that same thread. I wonder if it's true.

I see that the layered CPU/memory unit has a metal cover to it, im wondering if a thin thermal pad could be placed between them to conduct heat to the metal cover. Its not much of a heatsink, but it might help a little bit. It may even be possible to put a thin copper sheet on the metal cover to move heat away. It all depends how much room there is under the plastic cover. The only teardown ive seen doesnt make it very clear.
