Is it dangerous heating the phone to up to 41C every day?

So I started playing this game Order and Chaos Online (kinda MMO similar to WoW) and the temps get very high, up to 41C on WiFi and 43C on 3g. The phone is burning to a point that it hurts my hand. I'm playing aprox 2-3 hours per day, sometimes maybe 4 hours, how dagerous is that to the phone? Can it do any significat damage over time?
I am using the jame bond kernel at 1ghz, which is also a bit undervolted, don't know the values tho, governer is set to ondemand. I tried to underclock it to 800mhz but the game lags sometimes and is a no-go.

ukhm, khm....

Well if the phone is heating up and it sounds pretty bad, I'm pretty sure its dangerous. Maybe not, but IMO it is. My Sprint HTC Hero has over heated a few times and after that it had small little dots on the screen. Hopefully your phone don't fry.

What are you usual temps? Do you ever get any values similar to mine?

Mines usually sits between 34°C - 36°C, its seems like a normal temp IMO. I've never had my phone hit 41°C before and I sometimes i tether my phone via usb and it still dosent hit that high. If your is hitting that high, it could also be the temp around your home or something. But I wouldn't use your phone to play MMO, especially if your playing 2-4hrs everyday. Just saying..

Well I'm at stock right now because I'm waiting for the ota tomorrow. But I was using koushdecks 1.2.1 with matr1x kernel 4.0 bfs version. Clocked it up to 1.3ghz - 100hz, switched between smatass to ondemand everyone ounce in awhile and I still was at 36°C. I use setcpu's widget to always check my temp and it never goes higher then 36°C. Fact.

Can anyone else pls tell their usual temps, this got me a bit worried. On browsing the net I achieve 38C, on some intensive games I can get over 40C. When idle it usually stays at 30C, sometimes in the morning I find it with 28C. Is this normal?

[Q] Is it normal for Nexus S to get hot in Hot Temperatures??

The temperature in my city is around 40°C.. But real-feel is around 42°C...Summer has just started and my phone is getting hotter than usual... However, the phone is not so hot in idle mode... Its around 31-33°C.. However, after playing few games or browsing for around 20-25 mins, my nexus s is getting hotter and hotter.. I can feel it in my hands... But still, the battery temp is showing 36-37°C only... I've never even seen 38°C on my phone... But still, I can feel the touchscreen is getting very very hot...
After opening the back cover, I began examining myself.. I noted:
The battery is not that hot
The sim area is very hot (I even started my phone without the SIM card, but same result)
The area beneath the camera and flash is also too hot..
The touchscreen itself is getting v.v hottttt.... I cannot play touch games anymore... However, the lower part of the touchscreen is absolutely normal...
When charging, the temperature doesn't goes more than 35°C... However, I can feel the back side is warmer...
2months ago, when the temp was around 30-32°C, I've never had this problem Everything was fine and running perfectly... Still now, everything runs smoothly without lags
I've never heard that touchscreen is hott... I've had many phones and my city's temp remains mild mostly... So, what could be the problem?
I am using:
Carbon unofficial
Marmite 8.5cm_bigmen
No over/under clocking
Vooodoo sound with +5db (Hardware highest)
Ondemand with cfq
Battery timings: 1.5day with normal use (4-5hrs of screen time)
1day with heavy use (6-7hrs of screen time)
Should I revert back to stock ROM?
Is there any IC problem?
Battery problem?
Processor problem?
Or is it normal for the phone to get hot in hot temperatures (42°C)???
Should I see a doctor?

Its normal dude. If you want to keep it cooler than don't keep the brightness too high.
One thing that can REALLY heat up my phone is playing games at 100% brightness on a hot day so try to avoid that.

No dude the same areas as you describe are the ones that can get really hot on my phone.

My i9023 gets really hot if i play games at max brightness, so now I avoid playing games.
And yes, it also gets hot in the processor area, not the battery.

Now, my phone is getting very hot while playing Asphalt 6 or even Fruit Ninja... Only the processor side (Top portion of touchscreen and its back portion) is getting hot... Battery is definitely cool (Not more than 38degree)...
What could be the problem? My processor has gone mad or what? I've even tried undervolting as well as processing speed to 800Mhz max... But overheating remains

My phone gets hot only when I'm on full brightness and a game I usually put it at half brightness and it never happens even when playing mc4

This is absolutely true. I have Nexus S since 4 months... There was no problem at all then.. everything normal and running fine and never overheated at all no matter what i play...
This overheating problem started few days back when I tested overclocking and overvolting NS
Seem's this is the problem..
I think I have roasted the processor and it will always remain like that.. I will have to sell it soon now

is it still over heating on half brightness?

It is... I am on 3% brightness...
Should I give a try to a new OEM battery?
Will it resolve the overheat issue?
Why is the processor heating up too quickly? Has I finished its life by overcloking it? Or it is a battery issue?

I went to the local market for some inspection of my phone. The person said that your phone is not giving maximum current and the charging ic is getting very hot and has to be changed... How is this possible? I've never had any problem with my phone like this... 100% charging was always OK for me

[Q] Nexus 5 gets hot

Hey guys, Im new to XDA but i have a quick question for all nexus 5 owners. Okay i was just wondering if anyone else's Nexus 5 gets hot. I remember my nexus 4 would get so hot i couldn't touch it. I haven't had that kind of heat from my nexus 5, but it is there and i do notice it. It gets hot near the camera on the back, and it gets hot on the front at the top of the screen. I have a CPU temp monitor running on my device to check if my device is running to warm. I found it averages/hovers around 50 degrees celsius. When i open chrome and do some light browsing it goes up to 60 degrees. So my question is.. Is anyone else noticing their phone gets hot? And does anyone have a cpu temp monitor running and could you let me know how hot your phone is running at?
Thanks

Mine gets hot after a fair amount of time of gaming. Nothing terribly uncomfortable, but noticeable nonetheless.

Yeah mine is warm after just 5 minutes of normal usage non-gaming situations. Not hot but warm. Its starts to get hot to the touch after 15 minutes of heavy usage (ie. Browsing, gaming, etc) . I don't know if this is worth calling Google about and having them replace it, or is everyone's phone like this and I just need to get used to it?

I gotta stop reading on this forum the more more I read about this phone its make me not want it does all the things my Galaxy Nexus does. too not while browsing the internet. Low speaker volume. No flash. Questionable battery life. Might go iPhone...smh

Chrome is the problem. Its resource heavy for no ****ing reason.
I've been using chrome and my phone doesn't work hard at all with the same amount of browsing and tabs I always have open.
So its not the phone. You can expect it to get warm when doing CPU intensive stuff. Gaming would be it. But not hot.

Ew no

guess what. youre using a 2,3ghz quad core device, ots gonna get hot when you use it. and itll cool down quick when you arent using it. thats how its supposed to be, thats how it works.

Okay i think it might be chrome as well. When playing temple run, my device only got to 58 celsius. But when browsing on chrome my device went up to 68 celsius. So now I'm thinking its just chrome?

As the other person stated - Chrome is a resource hog and definitely is part of it. Fully utilizing Google Now with the voice search activated (*okay Google*) can definitely do it. Try Chrome Beta, it's much better.

Does it get too hot to the point it won't charge? That what pisses me off most about my g-nex

i think its normal for the 'warm' touch at the back, it doesn't get quite as hot as the nexus4 becuase of the glass backing
i use tempMonitor app, i get around 47c cpu temp when its warm
im running r12 franco kernel UVing to 920mV at 1.95max ghz

Im using TempMonitor as well. When under normal circumstances (i.e. texting, calling, etc) my phone is running at 45 celsius. But it gets hot as soon as i go online or play a game for like 3-5 minutes. Im sure it must be chrome then. I understand the gaming part and how the processor works, but i didn't realize chrome was that bad. Ill try chrome beta. Anyone else know what temperature there cpu'c are running at?

my cpu is anywhere between 0C and 89C, depending what im doing with the phone. its normal to get hot, especially when doing something taxing. itll get hot, but itll cool down fast when the work is done. thats how its supposed to work. anyone complaining that device cpu temp is hot at 65C just doesnt know any better.

Lol well thats why I was asking and looking through the forums on XDA because I've never experienced a hot phone before. Im coming from the moto x which never got above 40C. That phone wasn't a snapdragon 800 though. I just wanted opinions of if it was just my phone or if everyones phone was like this. And if not should i send it in for replacement.

I know that this is BS because my note 3 which has the exact same processor never goes above 38-39 degrees Celsius even if I'm gaming for over an hour. If you think 89C is normal you're crazy.

what i see in this statement is pure ignorance. human body temperature is 37C, youre telling me that your cpu NEVER goes more than 1-2C over human body temp, even while gaming? do you live in the antarctic?
your only saving grace will be if you meant battery temperature, not cpu temperature. 39-40C would be normal then.

It's very easy to get wrong temperature readings from sensors btw. Trying to find a good app that reads them properly is not.
Parts of the phone warm up quickly but luckily the bottom bezel area does not.

CPU Temperature

I’m looking for the CPU temp in Galaxy S7.
Anybody know what are the values in green and red box in the pic attached signify?
This pic is from AIDA64/CPUZ

The red must be CPU cores, or at least related to that. Have no idea about the green one.

Wherever I see in the forums people only talk about the value in green box and they think that device is relatively cooler even under heavy load. But gotta say man the device heats up worse than my G4 even in minor load when referring to the values in the red box as you said. I wanna know is there something up with my device alone. What does you CPU Temp. reading after about 15 mins of heavy game session like with 'NFS No Limits' in your device in AIDA64? PLease post a screenshot

I don't play games on the phone. I tried a few just to make sure the phone is OK when gaming but in 5 minutes I got bored.
My phone gets hot, 75 Celsius when updating several apps, or right after an OTA.
I think this is normal, as I changed the first phone ( display issue ) and both reached the same temperatures in similar situations.
Edit
Also have a g4, that one gets hot more often than the s7.

Oh! Thanks for the reply. This is the first time using glass/metal phone, maybe that's why I'm very sensitive to this problem. Is that a S7(flat)? Never had seen anything above 60C.

Yes, simple s7, not edge.
One time got very hot in my pocket, for no apparent reason.
But in battery stats I noticed that Google services percentages increased from 6 to 16, in about 20 minutes. This happens also on g4, about once or twice a week. It lasts from 10 minutes to a half hour, or I restart the phone and no more issues for a while.
It's hard to catch the s7 above 70 Celsius, I guess the cooling system does it's job really fast. We need an app to monitor and record temperature changes in the background. The only one I know about is CPU temp, but is not showing real CPU temperatures, it's fake.

Got the same situation (temp around 65-70 degrees) especially when updating apps by play store. Its getting hot on the back near the camera. But when updating is done temperatures are very fast dropping to 30-40 degrees. I think it's normal for this kind of device, made from glass and metal. Would be greatful for more observations from you guys. Cheers.

Yeah, Most app in the place store aren't able to read the actual temperature from the S7. Maximum I've seen with those are 38C in ~20 min session of gaming. As I said haven't seen S7 anywhere near 70C but near 61C in AIDA64 but after ~20 min session of gaming. It does take about 5 mins to completely cool down. Don't know it's normal. Is it!?

As you can see from all the below linked videos, the temperature never crosses 40C in any testing under heavy load. But how can we get 60C, 70C and all. They are even saying device isn't much hot. How is that even posssible?

I have no idea what and how they tested, the fact is that mine got very hot a few times. I only check temps when I feel the phone hot, and that was only when updating some apps, right after the OTA restart.
The temps from a gun are going to be lower than the core sensor reading. Always.
Is this gun any good for external testing ? I almost bought it

Here are something based on my recent tests and findings,
The problem is when the device is under heavy load(NFS No Limits game). therm_zoneX values goes upto 61C, which I don't care if the device is still not much hot to hold in hand but it isn't. Compared to my LG G4 it gets hot soon for the same amount of load based on my tests. And makes me unpleasant of the fact that the I can't enjoy the amazing performance of gaming in this phone not even longer when compared to the HTC & LG phones I had. Even simple tasks like switching between Whatsapp and Tapatalk in the background for almost 5 min made the device unusually warm while there isn't anything else heavy running in the background. All these is considering the fact that my room temperature isn't very hot. What is your opinion?
I think the below attached images(4) will help you understand it better on the temp. variations on various tasks and where do I feel it warm/hot. I strongly believe it's unusual based on my experience in previous 5 years with various devices. Do you observe something similar. Please have a look.
PS: The NFS No Limits temp. readings were similar to someone who posted in the different thread.

Is 34°C on average/light use good?
36-37°C when updating apps and using the phone at the same time

Samsung GS7 overheating during camera usage

Hi,
I'm using a GS7 TMO version unlocked (SM G930T).
I've been using the same for a couple of days and I find that the device overheats (max 56.7°C so far).
Also this temperature shoot up happens only when camera is being used (I made sure all the apps are closed and wifi/bluetooth/location is turned off).
Has anyone experienced this issue so far? What is the normal temperature range and what is the max that have been observed in your device?

Phone info app that I installed from Play store. I cross checked the same with CPU-Z app as well.
Could you share your observation for reference?

so, first, if it ist the CPU temp then it is absolute ok.
Mine goes up to 75°C till it throttles down...
I have the Exynos Chip

Thanks for the reply, yes it is the CPU temperature. I'm a bit worried as just opening the camera app shoots up the temperature.

it is the core Temperature - does the Phone itself get warm/hot?

Anyone else observing the issue? It's worrying me a lot as the normal temperature itself is around 41* C.

how long you using the camera for ? my S7 camera only jumps from around 27.7C to 29.8C for photos
then after 10-15 mins usage jumps to 34.5C
