Mi 9T Pro underclock CPU/GPU - Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe

How can I underclock my 9T Pro smartphone? I don't play games or use power intensive apps, I'm thinking to underclock it's CPU and/or GPU to extend battery life.
I'm on latest MIUI 11 Beta from xiaomi.eu, rooted.
Are there any apps or methods to safely reduce frequencies for its CPU/GPU?

Root and a kernel manager like FKM.

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.

Thanks!
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.

Try to use kernel iMMENSITY-RAPHAEL-V24.0-MIUI-BETA-24-03-2020 version. It's really recommend for miui11 latest beta.

I'm trying underclocking, not overclocking.

I am sorry I meant to say changing clock at kernel level that is.
I may be wrong though.

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.

Anyone is able to do a kernel ( possible based on cyanogenmod) with overclock support?
If is possible, add the maximum overclock on snapdragon 820...
This will get us more performance and higher benchmark

This phone/CPU/GPU handles almost all content the Play Store can throw at it with ease. You may have slight FPS drops with the odd game, but you are not going to rewrite history gaining 4fps from a marginal over clock and even then you'd be better over clocking the GPU not the CPU anyway.
I agree with others. This obsession with Antutu scores is utterly pointless. And overclocks are a monumental waste of battery in the form of heat.
This obsession is almost as annoying as the folk that don't use any apps and wake their screen every now and then too increase screen on time, to then boast that they managed 12hours SOT.

That is false... The storage solution is what makes things Load quicker and what governor/io scheduler youre using. Over clocking is useless and trust me I know, I've over clocked every phone of mine until I realized all it does is cause instability, less battery life and more heating. The only viable over clocking is the GPU.

Custom kernels for the OP3T purposely underclocks the CPU to the same frequencies as the SD820 due to stability reasons. The stock kernel allows for the CPU to achieve higher frequencies and then throttles it down to prevent crashes. There is likely slightly reduced performance in custom kernels compared to the stock kernel, though I don't think it should result in noticeable lag. Are you sure your ElementalX kernel isn't set to power saving mode? Maybe try to set it to performance to test it out, or change the CPU governors.
You can change cpu speeds in the aroma installer when installing through twrp. There are several options I usually just use the default and still get great performance for scrubbing including games. You can also change cpu speeds with the elemental x kernel manager app from the play store costs about 2 or 3 dollars definitely worth it cause it will also update the kernel for you.

ElementalX doesn't underclock the cpu.

overclocking not possible?

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

best custom ROM's for game performance

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 believe that would be dot-os

Question Underclocking + Undervolting Possible on Mi 11?

Hello. I was wondering if underclocking both the CPU and GPU on the Mi 11 would improve battery life & thermal performance. I know undervolting would require a custom kernel but I'm sure underclocking is possible only with the stock kernel & root. Has anyone tried doing it? Thank you.
Sure, but you must be rooted. Using Kernel Manager like EX Kernel or Franco Kernel (in my screenshots, i have underclock high values CPU & GPU). You can see in CPU Stats, frequencies "blocked" are not used, in game my Mi 11 keep fresh . Only underclocking is granted, for undervolting we will waiting for a custom kernel.

yeah custom kernels are required for volt change.. turn off 5g helps.
