I don't know if it works on OOS versions but it does, on the OB12. You need to be rooted to be doing this.
Lower the input boost to 1036 on the big and 556 on the small first. Now, change the governor of the big cluster to conservative and the small to ondemand or conservative , benefit!
To see the improvement in FPS, you need to go to developer options and switch on profile GPU rendering. For those who didn't understand this: lower the graph is, higher the fps. Hit thanks if helped
Where to change these settings?
Any kernel manager would do. I'd recommend kernel aduitor

Oh alright. Little governor ondemand seems quite fine right now.
By the way, are both governors interactive by default?

You'll see input boost in the bottom section of CPU in kernel adiutor. Core 1- 1036, core 3 -556 is what you've to do. It'll be 1324 default on both. I'm suggesting that for slightly better battery life

Lower SOTs are obvious, but to what degree is what matters. As far as I see, it's not that much.
GUYS, I recommend not to use this anymore. Oneplus has a reason to not release the kernel with conservative on . This is because conservative is not optimized for battery while interactive is. If interactive weren't optimized for battery, it'd be better than conservative for sure. I get only 4 hr sot on conservative but 5.5 on interactive. Though this is not placebo, it has a negative impact on SOT .
When I change big cluster to conservative, those cores will always stay above 2 GHz, as shown in Kernel Adiutor.

Good you realised that.. I did a little investigation on your tweak.. Apparently setting governor to conservative locks the frequency of big cluster to max possible, usually above 2 ghz and it will step down slowly ( by slow I mean really slow like 1-2 seconds). Thus causes you to have very less render times on gpu profile as shown in the xda portal post.. I opened up ex kernel manager and observed same freq in higher range.
After some time I just changed governor to interactive and changed minimum freq of big cluster to 2 ghz.. I observed the same render times as situation as time when conservative was set as governor...
So this tweak is nothing but type of placebo since ramping up freq can lead to faster processing
Edit.: Couple of people on xda portal have said the same.. I didn't check it..

Click to expand...

The "governor" is that piece of software that switches the CPU of you phone between the different speeds and voltages, thus it is responsible to some performance issues and the power consumption of the battery.
Or in other words:
The "wrong" governor results in poor battery duration, while another "wrong" governor may result in great battery duration but poor performance. The "best" governor is the one that switches the CPU to exactly that speed that is really needed so the system can run with full performance and best battery duration.
As user of the stock ROM you do not have the choice as the kernel supports exactly one specific governor (named ondemand). If you want to try the differnt governors try the Nova ROM of Noejn: this great ROM allows you to switch between several different governors.

Ondemand make lags.. But damn Stock kernel only supports craps..
What's new:-
added wheatley governor
added hotplug governor
added lionheart
added lionheartx
added Scary governor
added SavagedZen governot
Working of governers
WHEATLEY:- this is yet another governor for the users who want to save battery as much as they can
The governor intelligently set the frequencies according the usage of the CPU, if the usage is high then frequency will also be high and when usage is low it will set the low frequency
This governor is made by doing changes in the ondemand governor and can be used in the place of conservative
Click to expand...
Click to collapse
HOTPLUG:- The “hotplug” governor scales CPU frequency based on load, similar to“ondemand”. It scales up to the highest frequency when “up_threshold”is crossed and scales down one frequency at a time when “down_threshold”is crossed. Unlike those governors, target frequencies are determinedby directly accessing the CPUfreq frequency table, instead of takingsome percentage of maximum available frequency.
The key difference in the “hotplug” governor is that it will disableauxillary CPUs when the system is very idle, and enable them again oncethe system becomes busy. This is achieved by averaging load overmultiple sampling periods; if CPUs were online or offlined based on asingle sampling period then thrashing will occur
Sysfs entries exist for “hotplug_in_sampling_periods” and for“hotplug_out_sampling_periods” which determine how many consecutiveperiods get averaged to determine if auxillery CPUs should be onlined orofflined. Defaults are 5 periods and 20 periods respectively.Otherwise the standard sysfs entries you might find for “ondemand” and“conservative” governors are there.

LIONHEARTX:- LionheartX is based on Lionheart but has a few changes on the tunables and features a suspend profile based on Smartass governor.
Click to expand...
Click to collapse
LIONHEART:- Lionheart is a conservative-based governor which is based on samsung's update3 source. Tweaks comes from 1) Knzo 2) Morfic. The original idea comes from Netarchy. See here. The tunables (such as the thresholds and sampling rate) were changed so the governor behaves more like the performance one, at the cost of battery as the scaling is very aggressive.
Click to expand...
Click to collapse
SCARY:- This is just a weird governor. It's based on Conservative which has a slower ramping than Ondemand butthen again it has Smartass elements which is a governor with one the fastest rampings.
Click to expand...
Click to collapse
SAVAGED ZEN:- Another Smartass-based kernel with many modifications aiming to attain both better battery and performance.
Click to expand...
Click to collapse
LULZACTIVE:- This new find from Tegrak is based on Interactive & Smartass governors and is one of the favorites. When workload is greater than or equal to 60%, the governor scales up CPU to next higher step. When workload is less than 60%, governor scales down CPU to next lower step. When screen is off, frequency is locked to global scaling minimum frequency.
Click to expand...
Click to collapse
INTELLIDEMAND:- Intellidemand aka Intelligent Ondemand from Faux is yet another governor that's based on ondemand. Unlike what some usersbelieve, this governor is not the replacement for OC Daemon (Having different governors for sleep and awake). The original intellidemand behaves differently according to GPU usage. When GPUis really busy (gaming, maps, benchmarking, etc) intellidemand behaves like ondemand. When GPU is 'idling' (or moderately busy), intellidemand limits max frequency to a step depending on frequencies available in your device/kernel for saving battery. This is called browsing mode.

Click to collapse
ONDEMAND X:- governor code from latest linux (3.0 at the moment) source *plus* the suspend/wake logic. No further optimization is done.
Click to expand...
Click to collapse
ONDEMAND:- Available in most kernels, and the default governor in most kernels. When the CPU load reaches a certain point (see “up threshold” in Advanced Settings), ondemand will rapidly scale the CPU up to meet demand, then gradually scale the CPU down when it isn't needed.
Click to expand...
Click to collapse
INTERACTIVE:- Available in newer kernels, and becoming the default scaling option in some official Android kernels. The interactive governor is functionally similar to theondemand governor with an even greater focus on responsiveness.
Click to expand...
Click to collapse
CONSERVATIVE:- Available in some kernels. It is similar to the ondemand governor, but will scale the CPU up more gradually to better fit demand. Conservative provides a less responsive experience than ondemand, but can save battery.
Click to expand...
Click to collapse
PERFORMANCE:- Available in most kernels. It will keep the CPU running at the “max” set value at all times. This is a bit more efficient than simply setting “max” and “min” to thesame value and using ondemand because the system will not waste resources scanning for CPU load.

POWERSAVE:- Available in some kernels. It will keep the CPU running at the “min” set value at all times.

SMOOTHASS:- The same as the Smartass “governor” But MUCH moreaggressive & across the board this one has a better battery life that is about a third better than stock KERNEL.
Click to expand...
Click to collapse
INTERACTIVEX:- The same thing as interactive but it clocks the cpu downto 300mhz in sleep mode.
Click to expand...
Click to collapse
SMARTASS V2:- Is a re-working of the original smartass governor, it allows for the CPU to scale through all frequencies from the lowest you set to the highest, based on the load occuring. Basically it scales CPU based on realtime needs of the system, saV2 supposedly incorporates some more agressive settings for screen off, and I believe quicker scaling than the original smartass.

BRAZILIANWAX:- Similar to smartassV2. More aggressive ramping, so more performance, less battery.

Click to collapse
LAG FREE:- This driver is rather similar to the 'ondemand' governor both in its source code and its purpose, the difference is its optimization for better suitability in a battery powered environment.

these are the key upgrades in smartass v2 they are different from device to device
1. Smartass v2 have added a more aggressive screen off profile but if you have applied a screen off profile it will cause issue
2. Smartass v2 is more responsive than before
3. Smartass v2 have changed default frequency
4. Saves much power than before

I was told by the majority it goes in this order:
1) Pegasusq
2) Lulzactive
3) SmartassV2
4) Ondemand
5) Hotplug
6) Interactive
... and the rest.
And for IO Scheduler:
1) VR
2) CFQ
3) SIO
The truth is that, this is a Dual Core Phone with 1GB RAM, and improved Android 4.03+ kernel. So the previous hardware and software limitations NO LONGER applies. Coming FROM the DEVELOPERS of governors and schedulers the best ones seem to be:
1) InteractiveX2
2) HotplugX
3) Ondemand
... then lulzactive ~ pegasusq > smartassV2
And for IO Schedulers:
1) SIO
... then the rest
The truth is you should use the DEVELOPER recommended governor and sio scheduler, for an extensive period (1-2 days) and compare them. Finding what works best for you. After that's done, then you should go further stability testing with Voltage Control. Eg, UC your lowest frequency, OC your highest frequency and UV each step to the NEEDS of your device, each device is UNIQUE and functions DIFFERENTLY.
I think doing so you should extend your battery life by 1 or 1.5hour per cycle, while maintaining or increasing performance.
it all depends on the ROM + Kernel and more importantly the user and how they use their Note.
For me, I use Performance + Noop.. But ive had good results with pegasusq + sio
The only way to get the best combination is to try them all, But give them time to perform, Dont make a decision after 5 mins of usage, Test them heavily, Do some serious Gaming + Multitasking and chose one that outperforms the rest !
I'll start testing and post results from time to time.

I agree, governors even if they have the same stock names(i.e ondemand) has been heavily tweaked by the kernel dev so that you maximize performance and batt life. Start off by using the kernel/scheduler suggested by the kernel dev.
The only thing I care about is running out of juice when I don't have access to something that can charge my phone, as long as i get 10-15hrs off batt life and solid performance I'm good. Still I always bring a wall charger/usb cord with me if i really needed the extra juice.

This sentence doesn't make sense at all.
Unless you mean you can change or recharge the battery, which is straight-forward.
But you can "change" (increase) the performance. Just clear all background tasks, go to Voltage Control and overclock the cpu frequency upto 1.704GHz (with +1400mV) and keep it at that frequency by using the Performance governor. Also overclock your gpu upto 400MHz (with +1,000mV).
Though I don't recommend that, stability issues, warming issues and possible physical damage to your processor. But use the same concept, just not Overclock too much!

That's simply NOT true.
Otherwise you have your phone in deep sleep/idle far more than the average user, barely using your phone.
Other possibility is that you've severely underclocked your maximum frequency, and have a long time in idle.
Performance governor = Always on maximum frequency.
NOTE's maximum frequency uses 1300+ mV. The NOTE's battery size is 2,500 mAh. Simple maths will tell you 24hrs is impossible ; )
But it is true I'm not saying my phone will be awake for 24 hours I'm saying I charge it roughly every 24 hours, I know performance keeps the phone at max speeds but I am human I will sleep for about 8-9 hours, so in result so will my phone.
And I don't use my phone every minute of the day I do have work to do so my battery life is what I say it is. What I consider 'average use' might be absolute minimal use to you so maybe that's why you doubt me,
I personally don't mess with voltages and things cause I don't understand them but I use note core kernel which is highly tweaked and one of the best kernels for battery life

okay let me explain then it used to increase the max cpu clock speed if needed, like if you've clocked your cpu at 1.5 and the cpu gets exhausted with 100% usage then the cpu will be increased to given SyncThreshold value for sometime to lower the pressure on cpu,, in simple words it should not be lower than the max cpu Freq. and preferably disabling it is a better option.. and btw your settings are just awesome phone is not over heating also and thanks.

Ah that makes a lot of sense. Thanks.
EDIT: But then why was SyncThreshold less than Max by default?
EDIT2: Also, same thing's been done by this awesome guy @nicholaschum (Google searched 'CPU Sync Threshold' LOL):

I am also wondering why people are keeping it less than default it just makes no sense.
@Gnome You are a pro kernel dev, right? Can you please explain to us (noobs :laugh what is up with the SyncThreshold value and what exactly it does?

Kernel by Gnome :thumbup:

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.

CPU overclock since snapdragon 845 is not possible anymore.
For GPU try Candy.

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.
