So I usually use CPUSpy to monitor my CPU usage. This comes in handy once the device is rooted and I can see how custom kernels and settings affect battery life and cpu cycles. My LG G4 is the tmobile variant and obviously not currently rooted. I notice through CPUSpy that my cpu speed literally never exceeds 1440mhz.
I don't have any problems with that per say, everything on the device still runs buttery smooth without anything more than the occasional hiccup or lag. I'm curious if anyone else has monitored their CPU speeds and noticed the same thing? I just find it a little interesting.
CPU spy can't even see the A57 cores so there's no way it can see what speed it's running at.
4 cores are limited to 1.44 the rest are 1.8
I have not used CPUSpy. But CPU-Z will show you the speed of each of the 6 cores. As mentioned, the last 2 are the only ones I've seen reach 1.8GHz, the first 4 seem to top out at 1.4 GHz.
Ok.. Using cpu-z..
That's how mine looks "at rest". When it's sitting quietly, saving the battery. Crank up some apps, and you should see those clock speeds rise.
But, trying to improve my battery life, and keep the temps down, I've been hoping to see those numbers stay low, not actually show how high they can go
I agree.. As ive stated, the device runs great i just found it odd. It even calls it a 1.44ghz cpu in the cpu profile and mostly no matter how hard i push the device i cant break that speed
Right as CPU-Z opens, the clock speeds spiked briefly. I was able to get a screenshot quickly.
Do yours also jump up for a second or two right as the app opens?
This has been discussed already. As the previous post shows, they do get to 1.8Ghz when required.
Hi,
I own a huawei huawei p8 lite(ale-21), and it has a kirin 620 octa-core processor, where all 8 cores run up to 1.2ghz. Looking at the CPU information on antutu, it only ever showed 4 cores being active, cores 0,1,2 and 3, and never cores 4,5,6 and 7. Also, even though it showed them as 'sleep', it still shows they are operating at 99%. So, I installed CPU-Z, and it showed that cores 0,1,2 and 3 were on, and cores 4,5,6 and 7 were 'stopped'. So I started an antutu benchmark, and cores 4,5,6 and 7 still did not turn on, even when CPU load was 100%.
That's why I don't like octa cores, because the 8 cores, are not real...only four...so yeah...bull****...we have to deal with it
because the 8 cores, are not real

Sorry, but this is BS...
Some apps have problems with some SoCs & more than 4 Cores
Use CPUStats (and CPUBurn aswell)

"Use CPUStats (and CPUBurn aswell)"
Good advice the above.
I have a Honor 4c with a Kirin 620 octa-core cpu.
The benchmarks suggested that this cpu is either not very (multitasking) capable or, for some reason, the system keeps the last 4 cores inactive.
Using the CPUBurn app, I scheduled 8 threads.
Each was set to 90% core utilization (9 ms active and 1 ms sleep).
I started the job and opened the CPUStats app to check the cores.
Suprisingly, only the first 4 cores were utilized. The others remained almost inactive.
Even more suprisingly, with 16 threads again only the first 4 cores were utilized.
To make a long story short, when I scheduled 24 threads, all 8 cores were utilized.
My conclusion:
my phone (Huawei Honor 4C) is deliberately castrated by Huawei. The cpu is octa-core for sure, but under the default (factory) configuration is essentially a quad core and nothing more.
Maybe, the same applies to P8 Lite...
As we all know, the Snapdragon 810 processor in our OnePlus 2 phones is prone to overheat, especially during heavy tasks such as gaming. With the stock kernel (which probably most of you are using) this leads to the A57 cores being partially or fully shut down and the display - which generates additional heat - being dimmed in order for the phone to keep a healthy temperature (healthy for both its components and the hands that are holding it.) This, in turn, leads to lag when playing especially demanding games. Which in turn leads to a frustrated user.
With root access, it's possible to use custom kernels and/or custom thermal throttling profiles in order to (at least partially) circumvent these issues, by throttling the CPU frequency and/or limiting the number of active cores, using different schedulers and governors, and by applying thermal profiles that allow the phone to get hotter (in order to keep higher CPU frequencies for a longer duration).
Since I bought the OPT, I was playing a very power hungry game - Republique - which, at its highest graphics quality setting, pushes the phone to its limits. I quickly switched from the stock kernel to the Boeffla kernel and started experimenting with schedulers, governors, hotplugging settings, CPU/GPU frequencies and thermal profiles, but nothing I have done so far makes it possible to play the game for more than 15-20 minutes before some kind of throttling / heat control sets in and the game starts lagging.
I tried limiting both CPU clusters to only 2 cores while maintaining higher frequencies, I tried throttling the frequencies and keeping all 8 cores active, and I tried all kinds of solutions in-between with anything from 4-8 cores active and frequencies anywhere between 60% and 100%. I also tried the various thermal profiles that the kernel offers. But whatever I did, the game was either lagging right from the start, or running smoothly for about 15 minutes before the screen was dimmed and the CPU was throttled, leading to a laggy experience.
So my question is, what do you guys do to keep the OnePlus 2 from overheating during gaming, while at the same time maintaining a lag-free experience? I don't seem to get anywhere with anything I try, so I'd be extremely grateful for some useful input.

All the phones throttle while gaming. I use thermal extreme with boeffla kernel. And use 2 a53 at 1,3ghz and 2-4 a57 at 1,4ghz and I modified the throttle file and it underclock to 1,2ghz when it gets hot but it doesn't happen if you don't play longer than 30minutes and it doesn't lag either. You can leave stock settings but if course it will get hot quicker. Also with thermal hotplugged or something like that, I used it all cores online all the time at full speed and it doesn't throttle for a long time, so I don't know what overheating are you talking about. My nexus 5 throttle faster and disable 2 of 4 cores and leave the other 2 at half speed, and our processor overheats?. Oneplus throttle the device a lot because of the rumors, fortunately we can change that. Try what I said, cheers.

Thanks for the tip with thermal extreme! The implementation in the latest Boeffla kernel v1.1 beta1 seem to do a very good job of not letting the phone get too hot while at the same time not throttling the CPU too much. Today, the performance was stable for almost 30 minutes of gaming, and when I checked the CPU stats I saw that all cores were still active (2x A53 + 4x A57), and only throttled to 960 MHz. This still delivered enough performance. (I started the game with both CPU clusters at 1.2 GHz, so this also seemed to help with keeping the phone at an acceptable temperature. I'm sure it would've gotten much hotter much quicker at higher CPU frequencies.)
I have to admit though, I was playing inside in an unlit room and thus the screen wasn't at max. brightness. We'll see how it will perform during my next work break when I have to make the screen much brighter.

Does it throttle to 960mhz? for me never reach 1,2ghz. Playing real Racing for 30min it stays at 1,2ghz. And with thermal hotplugged (all cores enabled, all at stock freq gpu too) it doesnt throttle for 30 min, gpu only sometimes to 510mhz, i played 30 minutes and it didnt throttle, i dont know when it was going to throttle because i stop playing. But also, gaming with all cores and no throttling eats the battery.

I guess it throttled to 960 MHz because the game I'm currently playing (République) is pretty resource hungry.
Devs,
The performance of le 2 is very bad when it comes to gaming.
It is the same in every stock eui to miui and all lineage os ROMs like AICP which uses lineage is kernel.
As per my finding this is due to severe thermal throttling in eui as well as in lineage os 13 and 14.1.
Firstly the two A72 CORES don't run while any task making it like SD 650 and clock go soo down at reaching 34° to 35°c and at above temp all A72 CORES ARE DOWN in lineage is and only one works in stock eui, same goes with GPU under clocking starts at 32°c making gaming experience horrible,
Even kernel auditor don't have any control in any of the ROMs and in lineage is 14.1 27 Feb build it is told it have core control but it can make all A72 cores run couldn't control clock speeds and result is the same ,
So I request devs please make a kernel from scrap and don't take hints from eui kernel and give us good gaming experience.
Thank you

My findings were exactly same as yours, the cpu and gpu, both are underclocking for even slightest of temperature rise. This is bad, but the good news is, I figured out a way, by which we can disable this poorly configured thermal throtling.
Delete this file here: /system/etc/thermal-engine-s2.conf
I don't know it it is safe or not, but I have been gaming with my device after deleting this file for about 10 days and there is no explosions yet. Hahaha.
Also, if you want, instead of deleting this file, you can modify some parameters so that, it starts throttling after some really high temperatures, instead of current values, but I like deleting that file because some thermal throtlling algorthm is always embedded in soc anyways.

See your findings are correct but I myself renamed thermal config s2 but it didnot have any effect and at 33 ° I can see GPU under clocked at 432 MHz and CPU under clocks itself , and at 35° the lagging in games can be seen easily
Will try deleting the file also ,hoping it can have any effect

My cpu temp have gone over 60°c but I haven't seen any throttling in cpu or gpu. But when, that file was present, those temperatures were never reached because of thermal throttling.

At first, I thought the same. But yesterday, i have played asphalt 8 in bright sunlight(to test if there is some thermal throttling left embedded in soc). And I was right, it throttles down the gpu, big cores, small cores, even some cores went offline automatically. After the device was cooled, everything wqs back to normal. So, IMO, there is no harm even if we play in extreme conditions with the file deleted, thermal throttling will kick in when its needed. Although, I advise modifying the file to others. Hahaha

Thermal throttling happens even in the best chips. Most of the time, it's integrated in the lower level portions of the chip.
Just let it be, really. Thermal throttling is the way of the chip of protecting itself from heat damage. PC processors, for example, shut down when removing the fan and reaching critical temperatures.

Ya true it is present in every chip but optimizing is Also a thing right.
In le 2 the two A72 cores don't run at all above 30°(except when opening apps while it is cool ,so after 33 or 34° they are not used in anything,and 34 is average temp of the phone while using ,that means it just exactly works like a loweclocked SD 650 which even more throttled with each degree rise in temp and at 36 ° ( which is avg temperature while gaming ) phone turns off one more A72 core meaning three A72 cores are off and one a72 is throttle to around 800 mhz and even all a53 cores run at half clock speeds and till that time GPU also reaches below 350mhz and lower a and it impossible to run even minor games like subway surfers lag free,
And since lineage is kernel has taken hint from eui kernel ,it performs exactly the same as stock kernel which leaves us with no choice left.
@codeworkx please look into this issue and please build a kernel for gaming performance as SD 652 is getting wasted due to thermal throttling, @codeworkx I am sure you know this issue better than me ,please find time to work on it.

It is not working and would have been not working for you also just check with kernel auditor,
I have check it thoroughly .
I think you don't know how to check
Tell me the process you check

First i make the soc heat by playing games or running benchmarks, then i open kernel auiditor and check if maximum cpu freq gets lowered or automatically or not. But it doesn't happen after deleting that file. Also, the gameplay seems very fluid then before. I also check for gpu max freq.
Hey, I have Cool 1 (same Soc) and yes, very dissapointed because in second 1 starts the throtling...
I have Kernel auditor. Which settings should I force?
hello, very nice threat.
I had some different experiences.
For me throotling starts slightly at 37° and bigger at 39 or 40 ... this results to throotled big cores at 1248mhz and a gpu to 432
to avoid that I made some underclocking settings which gives my setting antutu score of 69000 instead of 82000 and a geekbench score of 1000/3500 which is giving me cool and fast gaming enough

After updating my xt1572 to nougut i notice that both big cpu cores are always online but in marshmallow in low load one big cpu core used to shut down. Is it have something to do with nougut battery drain?
My phone is rooted. It may not be possible to see big cpu status in nougut without root.
Hmm.. Both my big cores are always disabled and i find that annoying because it causes lag.

Which app you used to know that? In 3c toolbox without root it shows big cores are offline but with root it shows big cores are online. Maybe nougut doesn't let apps to know that big cpus are online or offline or their frequency. But cool tool's cpu gauge can show cpu load even for big cpus without root.
I have come to the conclusion that in 7.0 and up most if not all cpu apps are inaccurate. They are reporting different data from each other on locked devices and rooted devices. So hard to know which is accurate.
