after overclocking to 1.4ghz and letting stress test run for about and hour, my CPU temp showed being 50 celcius. thats where i stopped.
do we know where the tempurature starts becoming dangerous for the device? i would say mine ran for about 15 minutes at 50 degrees and it didnt seem to effect it.
maybe its a dumb question because i doubt i will do anything with the phone on daily use that will push the temp higher than that.....mostly out of curiosity.
nobody knows what the max safe temp is?
50C is too hot. Stay under 40C imo.

Right. I wonder how u got urs to 50. Mine heats up at just 46, and that is when I stop what I doing n let it cool down. 40-42 can be considered safe.
well. i fugured out that the cpu only gets that hot when i can setCPU in use, and set to performance.......wich i have sense discovered is a bad idea and no longer using setCPU for anything.
i ran linpack for 20 minutes yesterday on my new setup and it only got to 43. though the phone did lock up at 22 minutes.....thats probably a whole other issue
Specially while playing HD games like Modern Combat 4, The Dark Knight Rises, N.O.V.A 4 etc..............
My phone doesn't get hot more then 38-40 *C even after half and hour of HD gaming.
But I still want to know exactly what might be the max CPU and Battery Temperature limit?
Thank you.
I have T, but it's very similar phone.
The limit for the battery is around 60°C and for CPU it's around 100°C. Every temperature beyond the limit causes the phone to shut down.
Of course it's a softwate feature and you can disable this by deleting sysmon.cfg file in /system/etc but it's highly dangerous and completely unrecommended.
Hope this helps you!

i don't think you have to start a new thread to ask other question, just ask in your previous thread.
and tx(all xperia maybe) have some overheating control app in system that monitoring the thermal of the device ..you don't need to worry about it

Thank you very much. I don't worry about the temperature. But when HD gaming, i'm a little worried about the screen, cuz it gets hot too. I hope the temperature won't do any harm to my TX's screen.
I think the T and TX housing is too close to the Processor that's why it gets a little hotter rather then other phone. :cyclops:
Don't worry about the screen. It will be ok but remember not to heat your phone for a very long time because then it may damage.
Besides just take a look at PC's LCD monitors. Touch it and you will see it's pretty warm too It's normal.
And the last thing - the brighter your screen is, the faster your phone gets hot!

Thnaks for ur help. My Xperia TX never gets hot or even a little warm while Charging, Seeing Movie or Browsing. Just gets hot when high HD gaming. I am a Android game lover.
So can you tell me some ways to keep my Xperia TX as cool as possible while HD gaming.
Yes, here are some things I keep on using:
1. Lower screen's brightness when you don't need to have it bright.
2. Don't play while charging.
3. Downclock your CPU - f.e. from 1,5 GHz to 1,1 or 1,2 (don't use 1,0 GHz on JB because your phone will start to lag!). The games will still run and very good speed. In fact I don't see any differences between 1,5 GHz and 1,2 GHz especially in games like Modern Combat 4, Carmageddon etc. Your CPU will start to heat much slower.
4. Undervolt your CPU.
5. Don't play with any case etc. Another thing that "helpes" the heat not to escape out of your phone.
My setup is JB 9.1.A.0.140, 1,2 GHz, Ondemand, CFQ, UV -75mV.

I think the heating issue is common in all modern smartphones. I used HTC Smartphone like HTC Evo 3D, HTC Desire HD but they never gets hot no matter what you do with the phone. Even after hours of gaming battery temperature shows maximum 31-32 *C.
Thank you again mate. :laugh:
Well that's pretty interesting
Maybe yhese smartphones have pretty big space between the CPU and the battery so even when the CPU heats up it does not heat the battery.
On the Xperia T it's very close to the battery and not covered with any radiator or a piece of metal etc so the heat can easily "access" the battery and heat it up.

What is temperature limit for xperia m4? I ask because it becomes hot even when i play hill climb racing.
Guys, I don't know but Note gets heated up a lot from the camera Side.. the battery remains cool though.. what is this?. can It be stopped. I guess your notes must have been suffering from this? any solution?

Heating ....how much...generally while charging it gets heated up. Try some google aps any of those battery savers...they have an option to show the temperature. Also are you always of Wifi...if so your screen is sure to generate heat, which is normal.
Above all if it gets heated if you are not charging and not on Wifi does it cool down ? Considering your battery charge is above 70%.

The phone heats up near the camera because that is where the CPU is located.
Running 3D games and other apps that require the phone to run at high CPU frequencies will heat up your phone.
If you want to avoid heat completely, then you need to look into Under Clocking and Under Volting.
It's simpler with a rooted phone and a tool like Rom Toolbox Pro.
Under Clocking is where you limit the max CPU frequency the phone can use.
By default the Note is limited to 1400MHz, set the maximum frequency to a lower level, e.g. 1000MHz.
Under Volting is where you limit the current the CPU draws from the battery at certain frequencies.
Make sure you do some serious reading on XDA before you Under Volt, supplying too little current to the CPU will make the phone unstable and potentially corrupt data.
The advantages of Under Clocking and Under Volting are reduced heat and better battery life.
The disadvantages are potentially poorer performance in 3D games and other intense apps, and instability if Under Volted too far.
Hope this helps explain what you are experiencing and some potential mitigation.
Hello guys i was wondering do our HTC ONE have a temperature Sensor built in, what i mean by that is a sensor that is able to detect the temperature outside like if u are at home in your room etc.
The reason to ask you is because before few days when i was outside i was trying to make a picture and when i shoot it a pop message appear that flash cant be used because its too cold.
And i start to wonder when the device can measure the temperature outside why then on the market its not availible app that is doong that for real.

AFAIK there is a built in sensor to measure CPU and battery temperatures, so when it get very cold outside, the cpu can't run as it should, that's why you have this error message I think
To answer your question, I think the sensor we have only measures cpu temp and not direct outside temperature,
Please correct me if I'm wrong

i am not sure about the out-side temp sensor,
but a cold CPU can't run correct , i doubt that. as a cold CPU is a dream for any machine
and practically there is no such cold CPU unless it was cooled on purpose.
however i think the cold temp effects capacitors or other staff that can't work in low temp
but 95% its not the CPU.

all posters are correct its actually the sensor inside the battery that measure its temperature that is complaining when you try to take a pic. The cpu also has a thermometer but the colder a cpu the better it runs actually. Batteries cannot be too cool and also cannot be too hot. Not sure if you ever used the wifi tether for root user app back in the play store a while ago but it would show you your battery temp and as you tethered more and more the battery temp would go up. I'd also imagine the camera uses teh battery temp to assume the temp of the flash too.. if the bulb is too cold and flashes it could break.
cheers

Not correct at least at one point.
A CPU CAN be too cold.
But then we are talking about cryotech cooling systems that will cool the cpu several 100 degrees below zero. That would be so cold a cpu actually would not work because the electrons cant move or something like that(im not that technical too explain deeper).
Allso i have doubts when you say a battery cannot get too hot...?

yes thats what i meant by "practically there is no such cold CPU unless it was cooled on purpose."
and this is used to overclock some CPU's with a very high Freq. (thats what i know)
Well my Nexus 6 has started getting really hot even with moderate usage. Its not like it burns my hand but it gets uncomfortable at times and it worries me.
If I'm just browsing on chrome, checking out Facebook, or playing a simple game like Crossy Roads, the phone starts getting really warm and after a while its really hot. Even when on WiFi it becomes hot. I have to close all the apps and leave it for a while so that it cools down. I don't have a lot of apps open all the time and I have a lot of memory remaining.
I can't really figure out what's the problem, any suggestions?
Thanks.

+1 Facebook application consumes extreme amounts of battery and system resources. That would be my first suggestion as well. Uninstall Facebook and see if you notice an improvement.
It would be easier to suggest something if you let us know if you are stock or have been playing with roms/ kernels and their settings.... I have seen other phones get hot with too aggressive kernel settings.....
first off, what cpu temperature ate you talking about? secondly, feel does not give you am accurate temperature reading, all its does is show you if something is hotter, or cooler, than your hand. thirdly, your phone can get up to 99C in temp. at 100C, the boiling point of water, your phone would automatically shut down to cool off. now while using your phone, especially when using the cpu hard, it will get hot. but that is normal. you own a quad core phone with a 2.65ghz cpu. do you really expwct it to stay cold?
Thanks for the suggestions.
I'll try uninstalling Facebook and getting back to you. I've already uninstalled Facebook Messenger.
My CPU temperature is around 41 degrees Celsius and when it gets warm to the point that its uncomfortable is around 58-60 degrees Celsius.
In know it has a really powerful cpu but I don't always want to be holding a device that is warm to the point that it becomes uncomfortable.
Also I haven't even attempted rooting or changing the kernels so its all stock.

58-60C is VERY normal, when using the phone. so maybe a powerful phone isnt right for you.
But is it normal to feel warm? Even though its powerful shouldn't it stay cool? Is this happening to every Nexus 6 user? Sorry for the influx of questions

again, feel osnt an accurate way to kudge temperature. if your hand is cooler, the phone will feel more hot. your phones temp also is dependent on the air temp around you. as if its warmer outside, then the phone will get warmer. but yea, every nexus can and will get that warm. and at times, will get even warmer! try plugging in to a charger and streaming a movie. in this situation, ive seen my phone hit 74C. but thats normal as well. unlike deaktop computers, our phones dont have fans blowing to keep the cpu cool. we rely on an inactive way to keep our phones cooler, so its normal for the more powerfully phones to get warm, and even hot.
Try this.
I was having overheating issues. When gaming, charging, or just about anything other than the phone at an idle. I cleared the cache in recovery. That's it. I did not uninstall anything or modify anything in any way. And now I do not have those issues. Is that what fixed it? I do not know. Will it work for anyone else? I do not know that either. But, I'm pretty sure that if you can clear the cache with your stock recovery, it won't hurt anything. Maybe you will get lucky and it works. Bonus benefit, battery life improved for me as well. Maybe 20% better. I hope it helps you as much as it did for me.
Good Luck.

if you are having "overheating" issues, then you are saying that your phone hits 100C constantly and reboot? if not, its not an "overheating" issue, its an issue with you and some heat.

lol! im not saying youre lying! seriously. im just saying that the behavior that you experienced is odd, considering thermal throttle being there. i actively disable thermal throttle every single time i boot up. and i try, really try, but have not been able to reach 100C on my n6. and i run my cpu at 3032mhz high and low cpu speed. now my nexus 5 reaches shutdown very easy, it takes seconds to get it there. my n6, no matter how hard i push, purposefully, i can not get it to reach 100C. now your reboot might have been something completely different, and you not reaching thermal shutdown. but i doubt you would have known that, because you would need a live cpu temp in your status bar to see if you hit thermal shutdown. and i doubt you have a cpu temp showing in your status bar. i do
If your phone is 55+C while you are not using it very intensely there's a problem.
I listen to music, watch videos, play some games like clash of clans and I never break 50 Celsius.

youre probably looking at the battery temp. battery temp is different. if your battery hits 60C, youll automatically shut down. everyone i know with a nexus 6 sees over 50C cpu temp rather often. well, depending how hard you are using the cpu, and the temp around you.

Well I can't tell you how hot it was getting. But when I played Star Wars Galactic Defender while charging it got really hot, almost too hot to hold. Although I am sure that what I felt was nothing near the boiling point of water, it was enough to make the phone restart.It got hot under the same circumstances with 5.0. Just not that hot. But after the 5.1 update it started getting much hotter. At the time I wouldn't put it on a charger at night because of the crazy heat. After the cache clearing things have been much better. It doesn't even get warm when fast charging.

Partly. Through normal operation with stock interactive governor I sit around 40-50 playing music, opening coc, etc. Phone never feels hot in hand.
When I'm idling or reading something or casually scrolling I'm always sitting 35-40 CPU temp.
Obviously if I crank it up and lock to 2.6GHz and run some CPU stresses I quickly get up to 75C :laugh: but that isn't normal operation. Relaxed operation when the CPU is idling should sit pretty low.

using the cpu lightly or it just sitting there wont get it hot at all. listening to music is using the cpu very lightly. if it gets hot just sitting there, then that is a problem. thats usually caused by a process getting "stuck" and the cpu staying a 100% active. so the heat in that situation would be a symptom, but not the problem.
