I read Nokia user guide about battery temperature, they states that it is best to keep the temperature between 15°C to 25°C (59°F to 77°F) for optimal performance. However, my battery temperature is always 27°C or 30°C under normal uses. So I would like to ask if this is okay and does this also happen to your battery?
It means the external temperature a.k.a. The temperature of the environment.
Not the temperature of the battery.
Batteries dont like either too hot or too cold of environments.

Hi guys. This might be a stupid question, but is it possible to use liquid nitrogen cooling systems to cool our phone processor down to -200+ degrees centigrade then overclock it to Arm-V7 speeds (1GHZ+)? I asked this cos i read about superconductivity and I realised that by cooling the processor and possibly the RAM to that temperature, the resistance within the electrical systems would almost totally disappear, resulting in more processes being able to be carried out in a set amount of time.
Just curious

its not all about temperature. You must have enough voltage
P.S Dont worry about that... Its not possible

wait then if it's possible to overvolt your battery? Like cos while it will degrade battery life a lot, it essentially is still a bunch of dielectric sandwiched alternatingly between conductors. So to overvolt that infinitely technically would be possible, but the battery life will degrade exponentially
.......... I think this is a case of wrong application and understanding of superconductivity. That temperature alone probably will not trigger superconductivity for our processor and/or RAM.
Anyway, no. Practicality is one reason, and also because the processing capability has an upper limit. So does R/W speed. These are not solely dependent on voltage.

you need to connect car battery directly to cpu and good cooling loool 1 GHz

NO. Voltage of a battery is EMF, and is work done to push a charge around the circuit. Infinite voltage means either infinite energy or zero charge, both of which are impossible. You are missing out on many key factors here, and I suggest that you actually study and understand the concepts involved before discussing something.

Hi i have an idea for better battery durability and reduce the heat emitted.i want to change the processor's clock speed.
I think that 1-1.2 ghz is enough for good performance but i don't have rooted my phone yet so could anyone try to change the clock speed and wrote what about the battery drain and heat emitted by cpu?
Thanks!

I'm so glad that you had that idea, because nobody else has EVER thought about doing that
How about you search the forum and look at one of the many, many threads where this sort of thing is discussed instead of asking us to write the same thing over and over again :banghead:
i didn't find anything about that if you can pls share link with those threads or whatever like this

ok thanks @danie.wro i have read whole topic and i guess does it this app useful?
i want use all 4 cores but clocking down theirs cores to 1gzh or 1.2ghz in term of battery saving and heat will be change anything for sure?
another question is regular that overnight my phone lost about 15-20% of battery doing nothing?
Try to use CPU-Tuner. I use that and it's very useful.
thanks you too, but this app is for rooted phone instead gearbox runs on no rooted phone too i tried quadrant benchmark and i had lower score, let we see if this change something in term of battery drain and heat emitted xD
ok i have tried and i have positive feelings the battery withstand more time about 15-20% with clock speed set on 1ghz and 4 cores, and power saver with 1 core on 1ghz, but the heat emitted by battery hasn't changed much...
I have a question does NFC take a lot of power?

I'm guessing by the facts that it has a lower signal range than Bluetooth it uses less power than Bluetooth but still is a considerably big battery consumer.
Hi my xz is goes high tempreture in 15 minutes. but just 3d games. and performance is faills on games. I measured the temperature of 42C.cpu gauge and i measured 45C manuel home thermometer http://forum.xda-developers.com/images/smilies/laugh.gif When i playing real racing 3 10 minutes to 15 minutes fps is fail
is that problem just mine?
Do I need to take the service?

I think once the device reaches a certain temperature, it would start throttling its speed. I did an antutu benchmark and was getting around the 15k mark. Everyone were reporting that they were getting over 20k. I tried submerging the phone in cold water and ran the test, and got over 20k in antutu.

It depends on your ambient temperature. Some people may live in a continent where their room temperate is lower than 20 Celsius while the rest (like me) on average would be 30 Celsius.
If you don't mind it, you could unlock your bootloader, install the Doomkernel by DooMLoRD and undervolt your device. That would reduce heat significantly.

I can't comment on games as I didn't play a lot of games on the device seeing how the battery would drop rapidly. I played casual games which didn't require a high amount of power to process. Anyways, when I am outside and turn on the GPS to use it, the phone heats up rather quickly. Even when the camera is on the phone heats up.
its not just u, its the nature of the CPU, it gets hot quick plus it in a pretty close encloser (glass and plastic) so that doesnt help with heat dissipation
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)
Hey guys I need help here please, My nexus 6 temperature seems weird so I need to confirm with someone has the Nexus 6
I need to test the CPU and Battery temperature in 3 cases 1-out of deep sleep 2-normal usage like surfing on chrome 3-heavy usage Antutu test can achive that
You can use CPU Temp it will give you all the readings for battery and CPU in graph if you leave it running in the background
https://play.google.com/store/apps/details?id=com.yanyan.cputemp
It would be great if someone would help with this because I will to send the phone to Motorola UK next week for them to repair it if my phone temp is not normal
Thanks in advance

i dont even know your temp and i can tell you its normal. if it goes above 70C, cpu temp, then thermal throttle sets in. if it hits 100C, your device will automatically shut down. anything below 40C is normal when not being used. anything below 100C is normal when being used. it will all depend how hard you are pushing your cpu. the harder you push it, the higher the temps will go.
there isnt a normal temp that it should be at, when in deep sleep, when being used, and when being used hard. there are too many variables to answer that correctly. so, there is no standard temp that it should be at.

I didn't need a standard temps I'm just asking to know if my temps are normal because my phone can get really hot with really simple tasks such as surfing the internet I'm talking about 50+ for the CPU which we can say that can be normal since I live in tropical country but what is not normal is the battery temepreture which most of the time above 38 to 43 and that makes the phone hot when I'm holding it

50+ is normal. and your body temp is 37C, so your battery temp is not hot at all, but normal. your phone will shut down automatically if your battery temp reaches 60C(to cool off). the only way ive seen it reach that warm was with playing cpu intensive games while charging or by streaming a movie while charging.

samsung sets up their cpu much differently than how google does. the note 4 also has the same sized battery as the n6, but its battery lasts longer on average. google also adds in a cpu temp throttle, where samsung doesnt. and the cpu is completely different anyways.

Sorry to dig up an old thread but I wanted to mention a problem with the app you mentioned:
It turns out that app you mentioned: cpu temperature is actually only reporting battery temperature! (I confirmed by observing that the single reported temperature matched my phones battery temperature and was far less than any of the four cpu temperatures reported by cpu-z).
I am curious if anyone knows of an app that will provide a trend of cpu temperature(s) over time, rather than displaying only the present-time cpu temperatures like cpu-z
