Hi all,
I'm very annoyed from the Cpu throttling on my Xperia Z3+.
I don't have root, because it's not possible to backup DRM Keys without unlocking Bootloader. But someday it will be possible.
Is it possible to change the treshold of Cpu throtteling? Maybe by editing a File when I have root?.
Sorry for my bad english.

You can change the temperature it throttles at, but it pretty much reaches that temperature immediately. I don't believe the S810 in this phone can run at max frequency for longer than a few seconds.
I want to do the same , since I strongly believe, that without thermal throttling, cpu's temperature won't go very high

I don't want remove the throttling completly, but I want to set the temperature treshold higher. At 55° the S810 goes down with the perfomance. For example, the Galaxy S6 is much hotter before it throttles.
Perhaps we could also limit the 4 strong cores to a maximum of 1.8 GHz, as in OnePlus Two. Then the Xperia Z3 + / Z4 still has enough power, but is still not as fast hot. When the S810 is throttled, it is far below the 1.8 Ghz. Down to 700Mhz far as I know.

How do you know? Did you have a chance to test that?
When i play games like moderncombat5 i have 60fps but after a while the frames drop in some scenes where it didnt 3-5 minutes ago. When i check the cpu/gpu i can see that it throttles and causes these framedrops. But the phone doesnt get hot. Since it isnt possible to mess with thermal values at the moment. I wonder if there are some optimal cpu/gpu clocks where it will not throttle and performance will stay the same all time regardless of how much you stress the cpu/gpu. Because i'd rather have a underclocked cpu gpu than having thermal throttling while stressing the phone. On oneplus3 i didnt have this much thermal throttling playing mc5. I also feel the thermal throttling throttles way to early.
And yes i tried almost all kernels/roms out there it was a better experience on the op3
Thanks!
All CPUs have slight variations, some may be slightly more efficient than others of the same model. To get the best performance, you're going to have to underclock and test on your own phone bit by bit.

I dont remember. But it was hard to find. Anyways i found out that the cpu allways throttles down to little 1209 mhz and big 1440 mhz. When gpu is running on max clock. Will make further investigations now to find perfect cpu & gpu freq.
It seems regardless of what cpu profile / governor you use and regardless if the phone is charging or not. The cpu will allways throttle down to 1209 little and 1440 big. And the gpu also throttles but i can't monitor the exact values currently. This throttling even happens when gpu is running on min freq. And even when you set big or little cluster to min freq.
Im pretty sure the thermal throttling of the oneplus3 is broken. Because:
Thermal throttling should be decided by many factors. (General soc heat generated by gpu/cpu/and ram) also the system should be aware by the values and should handle it intelligently.)
It seems there is only one heatsensor used to throttle all at once and the throttling stops at 1209mhz little and 1440mhz big. If the temperature still rises the phone simply doesnt give a f*** why i think there isnt even a point of using this stock throttling method. And no its not accurate. And no its not usefull because, it throttles regardless what heat the phone has. Because it doesnt react to soc heat. It reacts to one of the components and throttles everything. Why it can't check the other temparatures aswell and throttle other components diffrently if even needed at all.
Issue: lets say little or big cluster is overheating because the cpu load is very high on it. (And no you wont see this throttling by simply running perf gov. It needs load/ working tasks on it, means you gotta play some heavy 3d games)
The thermal throttling just brakes down both clusters including the gpu. Was the big cluster or the gpu running cool? The thermal throttling doesn't give a f***. Could the loads/tasks been shared with or pushed to the big cluster. Thermal values dont care. Could some rly simple sort of hotplug turn the overhating little cluster off to let the big cluster do the rest before it rather throttles everything on the f... phone . -nope - Its annoying. Rly just try it out yourself. I really hope to see some improvements by oneplus. And no the phone is not bad at all. It's just some things are not optimized yet. Like touch latency which is worse than on galaxy s3 but i don't mind it just giving you an example so you can imagine how bad the thermal throttling must be.
Allways remember setting the cpu clock values so low that they dont throttle anymore doesnt mean gpu will throttle less often. All compenents will throttle without comparing other compents clock rate and heat.
My question: is the thermal throttling decided by the soc itself or are there different thermal throttling values on each phone brand using sd821?
And is it possible to port these values from lets say pixel phone?
I'm on cm13 and its kernel default is a bit lower than stock. I had the screen on full brightness and was charging the battery so temps above 100°. I played dead trigger 2 on highest settings on a level with lots of special effects and weapons with lots of splatter. Got throttled when the temp hit 103° everytime. I was running performance on cpu and gpu and i tested it without charging and still get throttled.

Im using laos 14.1 with latest ex kernel.
As is said thermal values are broken. Its not right to throttle down to same speed if charger is plugged as battery heat is higher and soc heat should be higher too. So i think it also throttles unnecesserily low without the charger being plugged.
Did any one find a solution to fix this?
Up up up
years of tired because of this ****ting throttling issue
Well do this at your own risk, go to system/vendor/bin and cut the file named "thermal-engine" to other directories in your sd card. This will completely disable thermal throttling. Perfect for gaming.?
Up up!!! This issues persists to me.. i even put my oneplus 3t in front of 8" fan for every gaming. Is there anyway to maintain the cpu frequency at higher rate during thermal throttling? I don't want to totally disable the thermal throttling... Seems unsafe... Enlighten me if you would
I think its time for gamer's to switch to a gaming oriented phone to avoid this thermal throttling and im looking forward to buy Black Shark which is Xiaomi backed gaming phone with custom rom (not miui) something different and that too is gaming focused hopefully it will be available globally soon ! :fingers-crossed:

There is no risk if you disable thermal throttling, the CPU will shut itself down if its temperature reaches 100°C

If i tilt my phone to the left for gaming, i will be burning my left thumb then.... even around cpu temp of 55.... My OnePlus 3T is gold in colour.. will it be better for heat dissipation if i change to midnight black?
LN2 + Copper pot. Should help.

There's nothing you can do about the throtting, OP3T throttles @60°C tbh in just 10 mins of game play it starts throtting
You have 2 options here
1. Either disable thermal engine as suggested by someone above ( it basically boils your device forget about gaming, temps touchs to 98°C if msm thermal is disabled and around 60 to 75°c it msm thermal is enabled it's seriously hot to touch and high chances of damaging internals
2. Underclock the big cluster to 1209MHz or 1286MHz I tested both, while gaming (2 hrs of pubg @ medium settings) temp's are around 53 to 55°c and never reached 60°c no throtting ( but you know what, games still lag or you will get low fps due to lack of power Lol I'm sorry that's true there nothing you can do about it try playing games in air conditioned room or just buy gaming Phone like Razer they have good heat dissipation, you should not forget the fact that our device is 2 years old. Tbh on a 2 year old phones even optimized games too use lot of processing power which lead more heat. More heat = throttle
When i open cpu control apps like 3c cpu manager and rom toolbox pro, the maximum frequency is set to 1.59 Mhz by default and i can't increase it. When i increase it, it again comes to 1.59. Any solution?
Using oneplus 3t
Overclocking depends on the kernel. If you are using the stock ROM and stock kernel, don't even hope.
If you have a supported kernel (not likely), use Kernel Adiutor. Much more up to date.
Also there's core control which will interfere as to make sure your CPU doesn't melt into a beautiful pile of liquid metal ?
As far as I know you shouldn't overclock your CPU, there may be some design problems with it, and becomes unstable. Sultanxda investigated the problem back in December, and it looks like even the stock rom must use some tricks (aggressive thermal throttling?) to reach maximum spec. frequency. Overclocking on custom roms lead to crashes.
Radioactive kernel for los based roms by @acuicultor has overclock. I use it and love it. Great sot, 7-9 hours easy, less if I game. I actually have the large cores underclocked to 2. though so that may help a little with my sot but it shouldn't affect it much at all

That is normal although the max frequency of the little cluster is 2.15Ghz as advertised by Qualcomm for Snapdragon 821.
According XDA review of oneplus 3T dated November 2016 https://www.xda-developers.com/oneplus-3t-xda-review-what-has-changed-and-by-how-much/ the Little cluster was clocking to 1.6Ghz (round off) as opposed to 2.15Ghz which is its maximum clockrate, it is safe to say that oneplus intentionally did that in order to save more battery.
Btw im using custom kernel ElementalX kernel based on Oxygen OS 4.1.1 and even I set the little cluster to its maximum 2.15Ghz it always reverts to 1.6Ghz.
As you can see OnePlus 3T is still blazing fast even the little cluster is a bit downclocked.

Radioactive kernel stays at 2.188Ghz for the little cluster for me even after reboot if I set it that way. I prefer 1.6Ghz, I like my insane sot. The big cluster oc at 2.419Ghz does not stay though, it automatically reverts back to 2.3Ghz. But I actually prefer to set it uc at 2.15Ghz. Still blazing fast.
EDIT: Using exkm aswell
OC more than possible
So here many custom ROM's
https://forum.xda-developers.com/mi-max-2/development/available-stock-custom-roms-mi-max-2-t3737523
Which of this the best for gaming? I don't care about my battery life or something else, only good optimization for games :laugh:
Also mb someone know how to tune Kernel Adiutor for gaming, is any guides or something else? i don't found any of this for Mi Max 2
It would be great, if u help
Without a custom Kernel, nothing much can be tuned in Kernel Adiutor to achieve higher performance in games. OC-ing the GPU and CPU would be probably the only solution to gain more FPS. All this ROMs are gonna perform similar with the same kernel.

optimization for games in kernel adiutor is actually pretty straight forward. just choose performance governor for both cpu and gpu and lock both to the highest possible clocks (cpu minimum and maximum 2016 mhz, gpu min and max 650 mhz). that way they wont be downclocking to save power and ull have max performance always
furthermore, u could change IO scheduler to deadline for faster loading times and disable core control (as well as temperature and vdd control, depending on whether theyre active by default) in thermal tab. just keep an eye on device temperatures, cuz ull be basically removing throttling measures for hardware safety. although i doubt this should be a problem with an soc like SD625 in such a large device, but still...better be safe than sorry

Hi, another way to unlock the cpu at its maximal frequence is to use the mod called " unlimited " in the playstore from the mi-globe rom (miui based)
here is the link : http://forum.mi-globe.com/general-development-f34/app-miui-unlimited-t691.html
You can activate it on the fly, very cool. I use this rom

ok i just checked on my phone with LOS 14.1 installed. when u set min and max gpu frequency to 650 mhz and set perfomance profile the gpu will only downclock to 320 mhz if there is no load put onto it. if there is ANY load whatsoever (in my case a simple continuous finger swipe over the display) the gpu clock sticks to 650 mhz and stays there.
so no worries, uve unlocked ur SoC performance completely and ull get the most out of it during gaming
edit: btw, dont let the poll results fool you. most people just go with LOS because thats what they are accustomed to the most and because its been out the longest for mi max 2 as far as custom roms are concerned. so more people voting there doesnt mean its actually faster than other roms (likely that most people havent tried ALL roms, especially for gaming-specific purposes )

I tried Franco's app but some CPU frequency settings don't maintain after a while.
And I'm sure I don't know exactly what frequencies should I modify (and how much) on the three clusters to obtain a balanced setting.
Not no mention GPU frequency settings...

Sorry I won't be much help on this as I haven't needed to change frequencies in a while. Afaik you just need to change the CPU and GPU governors to power save and set it to apply on reboot, small cores like to jump up a lot more max freq than the big cores so maybe around 1500mhz for small, keep large cores from going into 2000mhz and prime core too, GPU from what I remember really struggles if limited to lowest frequency, 300ish is a good starting point.
Depends on what rom you are running too, miui you don't really have a choice but to use stock kernel. On custom rom you have a lot more choices of kernel like immensity, f1xy, kraven and notkernel.

I'm using MIUI 11 latest weekly from xiaomi.eu.
Right now I applied your suggestions in FKM, I'm waiting to see how it influences the performance and power usage.
Well, I tested changing frequencies and governors in FKM but they won't stay after restart, even if apply after boot was checked for each modification. I guess MIUI kernel is not so friendly in this matter.

So, if this is true, changing freqs can't be done even in custom ROMs (non MIUI) and it's bad.
I tried lowering screen resolution and DPI to save power but the rounded corners become even rounder (?!) and power usage didn't drop that much.
