Hi all.
I am interested in locating the current SOC/CPU temperature on an Android Nexus 5 under operation. It is easy to retrieve the CPU frequency for each core by reading of the values from /sys/devices/system/cpu/cpu1/cpufreq/scaling_cur_freq while the phone is connected to a client - but the SoC temperature is usually found in different locations - based on the device / SoC vendor.
The device under test - holds a Snapdragon 800 / Hammerhead, revision 2.2, Plattform version 65536 - running Android 4.4.2
Our interest is to correctly identify when the device starts to throttle the frequency - and to report the accurate temperature at that moment. The work is used within the context of academic research. My role as a student is to identify how high temeperatures can affect throughput in computing intensive environments - and thus, more accurately provide reproducable results.
I am not interested in locating an app for this. I am interested in locating the thermal endpoint that reports the operating temperatue of the SoC. I am going to write the app myself - and dont need the overhead and interference of background services.
We have previously done this with the Samsung Galaxy Nexus, running on a Texas Instruments based SoC (OMAP) - but as noted, different vendors, different locations.
I tried to ask for this information on the Qualcomm developer forums, but their boards function quirky.
In advance. Thank you.
I can tell you that the frequency throttle is 60c based upon the stock kernel.
the suspend temperature is 60c
the core throttle is 80c
core throttle suspend temperature is stock 80c
the temp in which the device will throttle untiul reduced is 5c, the core throttle temp hysteresis is 10.

Hi! My CPU temperature is about 80-82°C when gaming and about 65°C when browsing chrome, facebook and some otther apps. What do you think, is that okay?

Hi,
Bah, he will re read it in this case with all the explanation given, just a head up... He will finally understand some things about "pseudo" overheating?
I also replied in some of these threads here with the same thing, like you, these thread topics/questions/posts about "Nexus 5 hot, overheating, too hot etc..." like in the Nexus 4 section bother me, but it's just my opinion...
If not, I'm sorry to use the search function (quickly right)...
In any case it's not the goal of the OP to know "Why is my N5 overheating when I'm playing for 15 mins an heavy game" or something like that, I was replying to Algotis...

people tend to embellish, make things sound better than they actually are. if you see who is saying that their phones hot or not, youll notice people that are new to xda, or dont post much, that say their phone doesnt heat up. yet, you see more people who have been on xda a while, or post more often, post that the phone can get hot. personally, i believe in being truthful and honest, even if the truth isnt good.
We attempted to measure the temperature from the following thermal sensor location:
/sys/class/thermal/thermal_zone7/temp
The idea came from a forum post about CPU temperature measurement on Nexus 4 devices - where the vendor was Qualcomm as well.
I cannot confirm that this is the correct measurement point, but it does raise and fall based on workload - and the values make sense as they represents temperatures from 30-75 C.
Looking at the following measurements, leave little doubt that the temperature throttels. The frequency drops down to 1.2-1.5 GHZ after a few minutes.

Ok so the temperature in my room is 5degrees the tf has been closed up all night and ive just woken up turn on tf unlock look at cpu spy to check for deep sleep etc look on my clock i see on temp reading 20degrees i double check with other apps its the same the outer case was stone cold and i thought just how close is the temperature sensor to the cpu?

Um, the temp being displayed on the clock and your other apps is not a temperature reading of the current ambient temperature around the device.
To my knowledge, there is no temperature sensor located on the device to measure the local temperature. The temperature being displayed on your clock is coming from an outside source displaying your local outside temperature.

No i use the sense clock with battery temp readings and have a little digital weather station in my room which has almost become redundant because of the asus weather widget but you get my point.
My room temp was 5degrees my battery sensor was 20 so thats why i thought maybe the battery sensor is right next to the cpu
Sent from my tf101 using xda premium 1.4ghz
The temp sensor should be built inside the cpu, at least last time I checked that was the trend, not sure about this particular case. However! Electronics heat up extremely fast, for example my computer goes from off to the BIOS setup page and already it's more than 10 degrees above room temperature. And then it idles there, not gaining or losing anything significative, it's just at it's working temperature. So my guess is exactly that.
Also check the manual, the TF probably has a working temperature range between 0 - 35 Celsius, and it's not good to use it outside it's working range. Talking about room temperature, just to be clear.

Based on my TF, I can't help but wonder if those overclocking need to compensate for something more than just extra heat build up.

I have always wonder, how well dose android leverage multi core SOCS? I know from being a PC hardware geek that most developers are terrible and using all the power in multi core CPU's. I understand that in benches all the cores are used, but how often are task spread out over the cores in real life usage. My theory is that they are barely used yet I have no evidence to promote this.
Depends on the governor settings but they definitely use all cores a lot by default.
Install system monitor lite and see for yourself

Do you think this would scale well onto the 8 core SOCS? I was just wondering if they really offered good real life performance rather than just good benchmarks

Weird. I was just wondering this myself, mainly because I just dont know what kind of specs it would take to have me use something other than my N5 and I am a phone-whore.
There aren't many tasks that need more than 2 cores active at a time. Gaming is one of the few times a 3rd core will kick in from what I've seen.
Traditionally, encoding benefits a lot from multiple cores but that isn't a task people usually attempt on their mobile.

You said that it will trigger the third core while gaming. I have a Nexus 5 and it lags in a specific have game. Idon't think my Nexus is trigering all the cores as it happens on my PC with the same application. On pc All cores goes to 90% as i don't have a graphics card. On Nexus i can't get the game to run on 100% even when i drop down all the quality over performance. I know that the device can handle this game. It's just a bootle neckle a believe. It's running stock rom stock kernle On demand governor. It should trigger all the cores.....i'm very sad with that too as i have bought the device manly for use like this.

Which game are you talking about? Once the phone starts heating up within about 20-30minutes it will begin to thermal throttle the CPU cores and clock speeds.

I'm talking about Digimon Adventure (1.5GB rom) on PPSSPP it's not the only game that i'm having this problem. And i'm pretty sure that nexus is not "taking it serious". From the beggning of the game you can see it already laggin. When i zoom out and the back ground bacames large it goes around to 50% when have about 6 NPCs on the screen it hapens too. When battling its pretty unstable. Some times ti can take up to 200% and some time to 90 again on the same screen in 3 seconds just changing the perpective of the camera.
@update i have take the screenshots from system monitor.

That's an issue with the ROM and emulation. It's very common for emulated games to have frame rate issues and you probably need to play around with the render settings. Nothing to do with our phone specifically, check other forums for more advice on the subject.

Did you down clock your CPU? If not, it's probably an issue with the emulated PSP ROM. You can play around with the emulator's render settings to try and get smoother game play but I am no expert on the subject.

Never.....my Phone is all Stock. And CPU -Z says it is in On the demand governor. The emulator does support a incrediblle variety of multi threaded process like inputs and process. These features are optional and when i turn the process multithread on, it slow down a litle more. i believe that it occurs because of the limitation of the 2 cores and the Android not allowing it to use the others. The emulator have a version for PC. The same emulator does multithread on my I3 Quad core 3.1GHz.
Many years looking the same... but now antutu is completely redesigned and looks really nice.
You can now compare chipsets performance also ...
I know that lot's of people don't like it but many others do... I do!

As States before... 69k on my Mokee... But... It is more 70k than 69... Anyway, what a machine
Ooops... 70K... Getting better! Now with a few more apps installed... So I guess it has to do with the ROM... The apps you have installed have nothing to do with antutu score i guess... Just saying...

Our device will get slower when it's hot due to thermal throttling, the thermal engine controls both CPU and GPU. When charging, especially when it's over 60%, the temperature will reach a high value that may exceed the threshold imposed by the thermal engine. Thus, either the core speed will be clocked down (CPU0-3 max 600, CPU4-5 max 864) or they will be totally off. Same with GPU (max 300 when hot, 600 when normal). I think Xiaomi didn't notice that many of its customers live in the equator lines where the temperature is generally warm to hot (25-35) so the threshold values will be reached much sooner than those who use the phone in norther or souther area.
It's true... But in this version of antutu the scores dont get uch a diferente after 2 or 3 tests... In previous version I used to get 57k, then 54k and then 50k... In this version I get 70k, 69k and then 69k again... Not much of a diference in results after heating... Why would this happen? I never get less than 69k

Maybe you need to put more background apps to your phone as I do
Having a screenshot of Android Assistant (both Monitoring and Processes tabs) might help the analysis.
Around 70k is a very bad score I must say, for our hardware.
On last Antutu I got 59k score and for example my friends Iphone 6s had 57k.
Now I'm getting 69k, and he is getting 120k scores.....

TBH, that's not bad since you can buy FOUR Mi4C for an iPhone 6s. Twister Core in Apple A9 is the best single core processor to date (which Snapdragon 820 Kyro cores might be able to beat when it comes out seeing latest benchmark info). Our Snapdragon 808 is even nowhere near 810, how could you expect it would beat Apple A9? Here's the official AnTuTu list for each SoC:
IPhone 6s with 57k... In your dreams. Mrkubix go to sleep...
Sd820 still does not beat iPhone single core performance... Dont know how they did that twister... But they did it very well... Typhoon was already wonderful...
On rockchip's website they listed a play store app called SetCPU that could be used for overclocking the CPU. Has anyone tested this with good results? Searching on google, it seems that other people have been able to overclock the RK3188 CPU from stock 1.6ghz to 1.8ghz+ successfully. However, the overclocked RK3188 chip was in a miniPC rather than an Android Head Unit.
Rockchip website, scroll down to "Download SETCPU overclock app"

UPDATE 9/28/16
Users report noticeable increase in performance after adding a passive heatsink to the CPU and RAM.

Seems overclocking is locked by the kernel- we're limited to adjusting the governor through Kernel Adiutor, No-frills CPU Control, and SetCPU.

with that big cooler on mine, I am not worried about heat. Even loaded for minutes the board is at room temp. The heatsink is barely even warm. I still get frustrated drving my wives car with the 4.4.4 unit. God it is so much faster. I love the zipties though, looks as good as my 3m tape solution haha. After the paste gets good and hard, I may just remove the tape.
I tried to overclock. It will not keep the changes in the files. It is locked in the kernel.

Oooh, that sounds very nice! I was planning on dismounting the unit from the car for the coming weeks anyway, to see if I can get the v6.5 Malaysk firmware to play and do some other tweaks. So this one is a nice feature to test.
Anybody got an idea of how the cpu is cooled? In comparison to a tablet or minipc, I would say they have ample of room to do so, but the question is whether they actually did something.
i would be interested in seeing the results of someone else trying this out
Judging by past photos, there doesn't seem to be any active cooling whatsoever. Additionally, I don't believe passive cooling is even installed - it's just free air. In any case, my MTCD tends to get quite hot.
https://img.xda-cdn.com/XGgubcDPFwM...GdD8Un98jDL93VOVFZVGVWdwspoGnzs=w1547-h870-no
Might be a good idea to use a passive cooling ?
I downloaded Setcpu, but its not as easy as choosing a new setting. The stock frequency tables are all that are there. It allows you to load new frequencies from a .txt file. I haven't had a chance to do this yet.
i used setcpu for root and it works fine. The kernel is locked to 1.6 but..................
even under full load continually the cpu never went above 1.2
I went out bought a heatsink and put it on the cpu. Cranked it to performance and 1.6 on boot with setcpu
It is a completely different machine now. It works as well as my mtcb 3188. Today I got gps workin and a workin radio good day.
What passive heatsink did you buy?

just an aluminum fined one from a local shop. covers the memory and the cpu.
It still can peg the cpu with i loveradio and google driving maps open at the same time, but it no longer freezes and is usable. Takes maybe 5 seconds to open google maps if only thing running. It is usable now until it burns up.
They definitely had a heat/speed problem. If someone could unlock the kernel it would be better. It is usable now and no longer a piece of junk.
just got an email from joying, it does have a gps card slot, it is just inside the box. on the front left.

did you use a script or a cpu tool to switch it? if you used a script mind sharing it so i do not have to go looking for file location?
I did notice if I chose performance it would run at 1.6 also, on any other setting it never made it above 1.2 no matter how bad the load was. I would rather having it boot at 1.6 also. maybe 1.8 now that i know initd is working on maylay 6.5
maybe something like
echo "performance" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
it has a file that lists them all there also
Mine would go to 1.6 on interactive. I switched it to performance and it locked on 1.6, but I'm not sure how hot its getting. there doesn't seem to be a sensor. Will these shutdown or reboot if they get too hot? I was also able to make these changes using Kernel auditor which is free. I switched it back to stock. I dont know enough about these and how they protect themselves from heat. Is there a kernel source available anywhere?
what kind of unit you have? mine refused to go above 1.2, but it is all about the limits and timing maps on how high it lets it go, not just the max frequency.
it was slow as could be.
I have a joying unit.
Guys can you check in your phone how many cores are working at a time? I see only two cores working at a time and i think they are the slower ones
Any impact coz of this?

me too, since i switched back to stock build 39.2.A.0.327 benchmarck highest score i could get is 130355 and battery seems worse too, i used to have like more than 138000 and very decent battery life with Frago's Nougat Rom, so i've flashed it back on... no rooted stock build for me anymore i guess...

Oh you are not on original ROM... Well i guess there is some problem with the original one...
Mine is F8832 ... i guess the dual SIM Ver are suffering

Guys can you check in your phone how many cores are working at a time? I see only two cores working at a time and i think they are the slower ones
Any impact coz of this?

Same issue here, I tested with CPU-Z and CPU-X and is the same result, only 2 cores working.
Firmware: .327 (Nougat)
Region: Malaysia
Model: F8332
So, I think that is a bug of the reads, beacuse if you perform a Benchmark, the results are the same that when you use Marshmallow (with 4 cores).

Every core works as intended, the truth is that most of Play Store's apps are not configured for 820+ Kryos, they only detect the power saving cores most of the time.

Might be possible... I hope this is the case
No, i tested with benchmark software, it is 40% lesser mark compare the 6.0
I feel lag after updated to nougat.
And my old z3 is faster than XZ now.
Used to have at least 120k marks.

i'm on 7.0 nougat and on antutu i did 144.000. It's good? which is the best score for the xz?
7.0 39.2.A.0.361 Orange MCV FR/ES/PL/SK/RO
I was suprised to hear that so i've been testing my device with antutu, usually core 2 and 3 ( max 2150mhz) are off, but i think it's probably due to nougat update, once i saw them all working for a sec.
My scores are between 147k and 115k.
First highest score with rather cool device, room temperature 24C, WIFI, BT, internet connection, NFC, Auto rotation: OFF, screen brightness on- set to minimum.
After few tests device got hotter and scores dropped to about 125k. Then i tried to push it to the limit, all ON, screen brightness auto-set to max. Score dropped to 115k.
So throttling is there definitively. Score around 130k can show how device will behave in normal use and it is fast as it should be. In case of my device, battery life has improved but it might be placebo effect
After update to latest nougat, the another 2cpu is back, but only for some minutes.
I just updated the cpu-z, and it is showing all 4 cores working, at 2.15ghz can't make a screen shot because it is moving quickly to 1.5 or it stops.
Edit: forgot too say that I'm using stock rom, 7.0........ 39.2.A.0.374.
Checked and sadly I got the same problem :'(. Hope they fix it soon.
Um... So what kind of CPU load are you putting on your phone in order to make all 4 cores to work simultaneously? In other words, why are you expecting to see all 4 cores active in CPU-Z in the first place?
If your phone has nothing serious to do at the time, then even 2 cores being active is too much. You should see only 1.

I tried play high end game - HIT and switched to see, CPUZ still showed only 2 cores are active.
While after 30 mins-45 mins of playing, it became laggy and not responding until I restart that game.
