Hello guys , i recently rooted my phone successfully! I really didnt like how lg operated this phone , simple games was micro lagging , not as smooth as adreno 530 was marketed. When i set the cpu on ondemand governor and disabling thermal core control all games became smooth as butter , really love it this way. I am playing my games with base optimisation so it downscales the resolution but my device didn't warm up at all, so i decided to mess with thermal throttling settings....
Here is what i found after searching with Solid Explorer , go to ROOT>SYSTEM>ETC>thermal-engine-8996.conf
Thats the log for the thermal control:

After studding a bit and making way too much testings on my phone , i could make it , mod will be soon available i am still testing it to make sure its stable as rock!
Take a look at the thumbnails below
I just Deleted the whole file and scored 144170!!! Everything was increased a bit , i am going to test it more and update the thread! 2nd 3D scrore also was improved a bit (1000 points, throttled less) , it just might work with default settings now ,at least i hope...
*** Dont delete the file , device won't throttle , i was playing real racing 3 cpu hit 80C (thats not good) and gpy 67c (not bad at all) so i am going back to edit the log!!!
Thanks for the information and that you shared this. I will perhaps include in my Custom Kernel.

Thats why i shared it , i have been testing it all the day , by increasing the values on threshold (temps) and the last ones (mhz) i got a little more perf but you can't get more than that , even if you delete both gpu tables still throttling occurs during benchmarks. In order to delay more the GPU throttling temp you need to increase throttling values of the CPU and that makes also the phone hotter but things like performance doesnt go with low temps....

I've noticed I get the screen brightness all the way up and it starts dimming when it gets kinda hot. If I erase the file will my screen brightness stay bright?

Sorry for the late answer , if your phone warms up just stock dont delete the whole file , just delete the "lcd on" and "daylight" columns. That should do the trick! :good:

Today I was sick and I decided the spend the day testing the phone. This configuration is great for battery life and stable
For cpu
1200000 1175
1100000 1125
1000000 1075
900000 1025
800000 975
700000 950
600000 950
500000 950
400000 900
300000 850
200000 825
100000 800
According to the tests I've done 86% of the time, cpu is below 600MHz state. Also I've decided to insert the 100mhz. It works great without any problems and we can save up a bunch of juice, near - 150mv.
Would recommend you guys leave the 500mhz till 800MHz as is. Or it'll freeze the phone.
Any thoughts? Wanna know your opinion.
The Gpu cannot be undervolted the limit is 1000mv for 200mhz and 267mhz.
160mhz I would love to test with 925mv
100MHz is 900mv
64mhz us 850mv
The only thing we can do to make sure it'll conserve battery is to raise the percentage before he raises frequency. I've decided to make near 85% to raise and 75% to decrease with 5 steps. Seems to be A OK.
Wanna know opinions. Phone is working great for hours with gaming etc. Please let me know your opinion

Hi,
I ran some basic tests with some benchmarks and also use ROM Toolbox to look at CPU min/max frequency.
I can confirm that running things like AnTuTU and Vellamo cause the device to heat up and cap CPU speed at about 1.5 GHz.
This means that unless your device is sitting in a freezer it will throttle when running all out.
There are some files that look to control this behavior in /system/etc/
thermal-engine.conf
thermal-engine-8974.conf
thermal-engine-8974-default.conf
and finally thermald.conf which is a brokent sym link.
Anyone ever play with these?
I'm sure a great kernel Dev will fix us up soon

The only one you need to play with is thermal-engine-8974.conf. Two of the others are sym links (one broken) and the other seems to hold values for shutting the phone down due to high cpu temps (115 Celsius), although these values are also in thermal-engine-8974.conf with slightly different values. It seems there is a lot of different types of throttling involved on this phone by looking at this file.
Although I don't know all the details, it seems threshold is the temp in Celsius (multiplied by 10000 under batt_therm_monitor, multiplied by 1000 in all other places) that the throttling takes place. Thresholds_clr seems to be where that throttling stops when the temp cools. Some categories have multiple levels of throttling. CPU_LCD_management has 6.
Changing these two values does work. You have to reboot after any changes you make for them to take effect. I have increased the memory speed throttle and the individual cpu throttle temps by 5 degrees (5000) on both the thresholds and thresholds_clr. I have increased all other thresholds and thresholds_clr by 10 degrees. I did not mess with the shutdown temps.
I should also note that I did try disabling thermal throttling entirely via the hidden menu and the phone would shutdown due to overheat during any benchmarks (thank goodness!). So this is why I decided to tweak these settings, since disabling it entirely seems to be a bad idea. Benchmarks are slightly higher and no shutdowns. Phone does get noticeably hotter.
This is what my thermal-engine-8974.conf looks like after modifying:

I figured it out, but thanks.
I tweaked mine a bit different but it still works like yours does.
No throttling during benchmarks.

Does anyone know of the same file's for a custom rom?
Please explain exactly what these thermals are doing
For example, here is a 4 core thermal

When I took a look at these kernels, there is little to no information in English. Usually thermals are editable across a broad range of non Xiaomi Phones.
For those of you using the modified thermal-engine-8996.conf files in this forum, I would recommend using these three specifications under the [KYRO_SS] area: (keep everything else the same)
set_point 49500
set_point_clr 45500
device_perf_floor 1324800
set_point determines a threshold for thermal throttling
set_point_clr determines when to stop thermal throttling
They don't equate exactly to the degrees in celsius for the CPU or battery, so I'm not sure exactly what the translation is. However, I found that this was a pretty good threshold to use to reduce the thermal throttling on the CPU.
By setting the device_perf_floor metric to a lower number, I could also make sure that thermal throttling DID happen when it was needed. This helped a lot to reduce the chances of my phone from overheating and shutting down during a hot summer day.
Hope this helps somebody! This really saved my phone.

The difference betwen the two methods is that 1824000 is actually kind of a high frequency to be thermal throttling at. (especially during the hot summer days we've been having lately in my state, my phone would just continue heating up and shutting down) I find that modifying set_point and set_point_clr are actually better since it increases the temperature setting BEFORE it starts throttling, but still throttles when it really needs to. This is especially helpful when using extended life batteries like the 6700 mAh batteries or 8500 mAh batteries which tend to run hotter than the average 3200 mAh batteries.
What I've observed is that if the extended batteries go above 51 degrees celsius, it starts kind of a chain reaction of heat between the CPU and battery that eventually causes the phone to overheat. I targeted the set_point and set_point_clr settings to cause it to throttle around this time to still make the phone usable, just slower for a short time.
I found that 1324800 was a good frequency to actually bring the temperature back down. When I set it at higher frequencies, the temperature for the battery would still stay around 51 degrees celsius or higher which was too hot for my taste.
i think my phone can handle it since i replaced the cheap paste with a premium paste......anyway i will test your method out to see if theres improvement
i want to ask what is the normal cpu temperature while gaming.my poco's cpu temperature goes upto 56 degree Celsius.plz reply
