Hey all,
So here is my issue. My clock frequency is doing some crazy stuff. For Cm based Roms, under performance the min frequency stays locked at 1026. I can move it down to 384 but it doesn't stick at all after I go back into the performance section its back up at 1026.
When I first get into the performance section the frequency is always at 1026 then quickly drops to 384. This is what happens in SetCpu as well.
Is this just a bug with the Nexus 4 or is something messed up? This happens on any Rom and Kernel (I've tried a good amount) and I've wiped everything every time. Does anyone know whats going on? This isn't my first unlocked and rooted phone.
Any help very much so appreciated.
That's normal. Mpdecison is active in that kernel, whenever you touch the screen the min is raised to 1ghz. Google added this for project butter, it's suppose to improve responsiveness and fluidity of the ui. Its unnecessary because the s4 is extremely fast and doesn't need some a boost, if this was an a8 then I would understand.

According to the System Tuner app, my CPU went up to 75 degrees Celsius while I was playing a track on Google Earth. I was running Earth for only a few minutes before it reached 75. I'm not sure if that's the peak yet...maybe it can go even higher.
I've seen several other threads about heat, but most people talk about 50s and 60s. Anyone reach 75C? The front and back of the phone, the top around the camera, were both very hot. It was almost uncomfortable to touch.
Again, I'm talking about 75 Celsius, not Fahrenheit. And I'm referring to CPU temperature according to System Tuner app, not battery temp. Anyone reach this?
picture plz.
the reason is bc someone did a stress test on the N4 and found that the device shuts down at ~57-59C (correct me if im wrong) to prevent damage to the hardware.
Edit: found the link http://www.youtube.com/watch?feature=player_embedded&v=koLJ4BU9tgc
75ºC on a quad core?
I thought it was supposed to be more efficient than a dual core... 167ºF just seems like it's way hotter than any electronic device should ever be.

My first gaming laptop was an ASUS Republic of Game first generation. They did a horrible job cooling the machine. During the 2 months before the machine failed, the GPU would reaches 110 - 140 C if I played games (then, of course, the machine turned the GPU off and still ran as everything else was still about 70-80 C)
When the machine did fail, I opened it up, and found 2 fried thermal unit, a fried GPU and a nearly fried HDD) Amazingly, the machine stills runs, as long as I don't load GPU driver
Well, that's the story. Back to OP, as you see, if the temp is too high, you device can be literally fried. So if you turn off the thermal throttle, please enable it back on and do you best to keep your device cool
I tried to replicate just now and could only go up to 63c. I don't want to keep trying based on the comments here so far. If it happens again I'll be sure to get a screen shot and be aware of what's running.
Where would the thermal throttle toggle exist, if I have the capability at all? I'm running faux123 kernel and use trickster mod and trinity kernel tools for tweaking. I don't see anything about throttle control.
On a similar note, faux123 seems to default to 1ghz minimum cpu frequency. Does that seem right? I've flashed lots of kernels before on previous phones and they always default to the lowest value. When I force the setting down to 384mhz, it automatically changes back to 1024mhz the next time I go in my tool apps. Does this seem normal?

I haven't seen a Nexus 4 kernel that has thermal throttle toggle, or have it disabled yet. I am just checking if you're running one that I am not aware of

Minimum cpu frequency enforced by kernel is normal. I am not certain if faux123 default to 1 ghz min, but if it's the case, it seems weird for me too. Definitely not good for the battery. If there's no other CPU control apps, I recommend double check the settings, then find an update for faux123, or use trinity kernel
I just flashed a new kernel and my minimum cpu now seems more normal. I hopefully that alleviates the crazy temperatures too.
I'll try to test again tomorrow to see if my temps still go bonkers. It's time to sleep now. Thanks for the help, everyone.
Not sure why but ever since I flashed release 7 of the faux kernel my phone just seemed to get really warm, now I don't know if i just never noticed it but I'm running Motley kernel now and my phone just gets warm at the top when installing apps. I'm not sure if I never noticed it and I'm starting too or if I have a problem, HELP? Thanks.
That's completely normal. When installing asps the CPU is being used. Also, the CPU governor being used and uv'ing affect the temperature. Also, the CPU is located at the top I'm guessing.

Hey, I'm wondering too ! Since i flashed the latest faux kernel (release 007m) , my phone seems to be warmer than usual. According to the system tuner widget the phone runs around 45°C after a few minutes of use and sometimes reaches almost 60°C while i do nothing special on my phone (a little browsing, sms). Despite the fact that I've downclocked the cpu to 1.35ghz, put the governor on intellidemand, disable mpdecision, UV 75 mV and running at the stock gpu clock. I don't know if this is normal but this seems to be a lot. What's gonna happen if I play games or some more intensive apps?
I know many will probably just ignore this bug, but I can't because just knowing it's there is pestering. Anyway the GPU is not functioning properly ever since 4.2.2 . Its frequency isn't dynamic.
I would like if some volunteers with faux clock or another GPU reading app could confirm if they have the same issue on 4.2.2 .

Default governor for GPU is ondemand, it's behaving properly.

On demand doesn't entail a static frequency. Previously it would drop to 128 or 200 but now it sticks to 400... That is definitely not normal behavior for this governor. I only had faux clock open and I doubt that app would be GPU intensive.
And this is a problem for me because the the back is noticeably warmer than before despite me having a max of 1ghz and eco mode.

Ah ok sorry, thought you meant it wasn't scaling through the frequencies on light loads.
Dunno may be it's using some kind of low power state instead, I'm using faux stock enhanced kernel and mine is cool at the back with just normal use, also getting great battery life.
Mine only gets hot with heavy gaming or by just browsing with 3g on.

My issue is that it sticks to 400 which is high state. The only time it changes is when I set it to 487, it'll switch between 487-->400 constantly. Something is triggering a load but these tests are on fresh installs. It's generating heat which isn't good for batteries, especially non removable.
All these issues with my nexus are seriously making me reconsider my purchase -_-

So I just wanted to see how normal this is, didn't see anybody else really mention anything about this. But my phone only really seems to want to use the 1566 MHz frequency range. It almost never uses any other frequency. Any body ever really notice this or is it not really that big of a deal?
https://www.dropbox.com/s/moqxq1agsriin54/2013-07-14 14.38.13.png
Edit: And for what its worth, I'm stock rooted. Left the governor on ondemand, had the I/O scheduler set to deadline for a while but set it back to CFQ with no changes(as expected). And my max frequency is set to 1890MHz, so it should go all the way up there, but there is almost no usage of those other frequencies, especially the higher ones which was weird since there was a while when I was trying to load it up to get to the higher frequencies.

I'm new to android, so my answer may not worth be much.. but what i've noticed in between switching roms and kernels and cpu apps, clean /dirty/whatever.. is that if you have been messing with cpu settings or voltages in any way then they will always have a small possibility of sticking even after you've deactivated or changed them back to default. the only way to get rid of these little bugs, at least for me, was to restore a stock/rooted/cwm nandroid backup or full wipe and full format under Mounts and Storage in recovery.. then flash back to the same rom i'm currently using.
basically.. the cpu can stick and you may need to reformat the system. seems to bethe case to me anyways.. hope it helps. if you can find a way to clear this issue without wiping data, please post the fix.
I found when running Shadowrun Returns with the ElementalX 1.4 kernel http://forum.xda-developers.com/showthread.php?t=2389022 at 1.944 GHZ the back of the Nexus 7 gets hot. This worried me but I noticed when I installed the kernel was an option to use cool thermal throttling. I tried this and now the tablet does not heat up at all. You need to be rooted though to install the kerne of course not sure if ElementalX 1.4 works with stock though, I'm running the latest CM 10.2 nightly. It doesn't seem to affect the performance of either Shadowrun Returns or Wild Blood, the two games I'm playing at the moment, I still have the GPU overclocked to 487 and the Dalvik etc overclocked at the moderate ElementalX setting. . I think being able to run at 1.944 GHZ on my tablet with the cooler thermal throttling is better then running at stock and I believe that even some running at stock have that issue.
Hope this helps others that have this problem.

That's a good sign as you know the heat is being distributed effectively away from the internals. You don't need to be rooted to flash custom kernel. And setting different governors will have a major impact on your CPU.

You might be right about not needing to root to install a custom kernel though I couldn't find a definitive answer in the Nexus 7 2013 forums. I assumed it was needed from using custom kernels on other devices.
My device gets hot while gaming. When you are doing intense gaming like I am I'm sure pretty much any governor will max out the CPU. I know Intellidemand which I use does for sure.
When overclocking, heat is the enemy and it can damage, crash CPUs and even affect the performance of them. I believe if you are concerned about your Nexus 7 heating up (mine does for a good area between the logo and the camera when not using the ElementalX cool thermal throttling) then my advice is good.
Peace.
P.S. How the heck have you done 675 posts since June 2013?

Kernel is flashed separately from the ROM. Rooting is only for running apps like Trickster Mod to configure to kernel. Otherwise you can have stock 4.3 ROM with any kernel you want. Heating up will obvious affect performance due to thermal throttling but I was not concerned of damage even when the CPU of my 2012 Nexus 7 got to 80 degrees celsius from running overclocked performance stress test under direct sunlight in a case. If your CPU crashes then it's likely not overclocked correctly. Otherwise if it remains stable under artificial stress test, it will handle any game no problem.
I would really appreciate if someone explain me how exactly this function works?
I mean, tablet don't have fan, so how it keeps the cpu cool, and also what this option does to my nexus in order to keep it cooler?
I would not over clock this device. It us more than fast enough for any Android game.
Throttling does just what the word describes. In basic terms your cpu will be slowed down when getting hot and this defeats the purpose of over clocking.
I won't mention the instability that can be caused or the possibility of doing damage.
Just my thoughts.. To each how own and I do have my I7 pc cpu over clocked big time but it has a huge fan.
Sent from my shiny new(bought last Nov), scratch less Nexus 4!
I agreed, throttling and over clock doesn't make sense but this CPU is underclocked and it is designed to go higher like the one on the galaxy s4 and the GPU is meant to go higher but due to battery life Google underclock it

Well , its not under clocked by Google, this is underclocked cheap from the factory , its just a lower bin s600 that has been rebranded as S4 Pro .. If it was regular s600 it wouldn't be underclocked .

When the CPU reaches a certain temperature threshold it begins to cycle down the CPU speed in order to cool down the processor. It makes the CPU start running at lower frequencies to keep it cool.
Exactly, so a quick oc and u got a better processor without worries of damaging the chip

Trickster Mod Thermal Throttling Settings
Hey,
If your CPU is getting hot (especially if it's overclocked and hitting 80 C or near to it) At 1944 the back of my case would get noticeably hot. I still say it isn't good for the CPU. From what I know about overclocking if any CPU gets too hot it can damage the CPU or degrade it over time. I definitely wouldn't want it even getting to 80C before it throttles but I found in Trickster Mod, even the free version, you can set the throttling to custom settings if you are rooted. Custom kernels set their voltages to scale depending on the clock speed which means lower clock speeds, less voltages, less heat. I'd rather keep the temps lower on the CPU then risk damaging the device or degrading it over time. Also you can undervolt the CPU at the kernel different clock speeds so it heats up less. You can run the free AnTuTu Benchmark stability test to see if your clock speed voltages are stable and will not crash your device. I have my CPU overclocked to 1944, thermal throttling down clocks the CPU to 1836 at 73 C, 1620 at 75 C, 1512 at 77 C and 1134 at 80 C. My voltages I lowered and are stable at 1944 - 1087500, 1890 - 1062500, 1836 - 1035000, 1728 - 1025000, 1620 - 1000000, 1512 - 987500. The lower voltages are undervolted as well but not going to list them all here.
Peace,
KedarWolf
P.S. When it was posted in this thread you can install custom kernels without rooting it is correct, I recall reading that at one point. Like it was said to use Trickster Mod, change governors or custom throttling settings you need to be rooted.
