Mi4i - Only Four cores are running most of the time, resulting in lagging performance - Xiaomi Mi 4i

Hello,
Mi 4i lags/slows down most of the time, when i check CPU-Z during that time, i can see that only the lower clocked 2/4 cpu cores run constantly at 800 Mhz. It is very difficult to use when it is so slow. Other 4/6 cores remain inactive.
Is there any solution for this weird behavior while running in Balanced mode. Even when switching to Performance mode, nothing changes. I believe due to the heat generated, the OS automatically underclocks the CPU. I have already rooted and tried changing the CPU Governor, Clock speed but it resets to default every time. Sometimes i am unable to change that too.
Thank you.

There's a configuration that does this, just try to use the provided tweaks available here and then configure the phone's cores and so manually.

I tried tweaking the thermal config using the above thread. But still only four cores are active @ 800 Mhz. The phone is so lagging that it is not usable at most of the time. Unable to change governor in any CPU clocking app, turn on the other cores. If you can help me out, please let me know.
Thanks.

Might be a bug. Try a clean install and see

Same here
I am having a similar issue, very frustrating. I tried Sensei kernel, but no luck

i don't know what do you mean bro
everytime i change to other rom,other kernel
the results is...
all core is on

strange, i am using miuipro with sensei and havent found any problem.

This happens in the latest stable MIUI7 ROM. I think it is time to change to a custom rom.

[APPS] Best SetCPU Settings

anyone got what they think is the best configuration for SetCPU?
stock configuration works great for me
min cpu = 225 (or something like that)
max cpu = 995 (again, or something like that)
????
Stock settings are:
Min: 245
Max: 998
CPU Governer: On demand
Charging 998/998
Sleep/Standby 499/245
Power < 25% 576/245
i concur about the stock clock settings, they work best for me. 998 high/245 low
i am opting for stock... im going to assume that htc/google did their research to give us the best blend of CPU speeds depending on what the phone is doing and what the battery power is...
if stock settings are 998 mhz why overclock it? can you get more from the processor than that?

you probably can, but you'd just end up burning it out. what you can do is set the low a bit higher than 245. more battery drain will result.
So what are the out of the box settings on the CPU if you dont use setCPU?
Read this thread you will see them
No one has messed with this app?
I have mine set @ stock, but have also enabled a profile for when the phone is asleep. I set it at 300/245. Not really sure if it makes a difference in battery life.
Mine is set to the A1clock speed which is 768max and 245 min.. no lag when swippin and in act1 video player its still smooth..even a droids 550mhz stock speed. Also got it 245max/min when sleep, remember to exclude setcpu if you u wanna see results..

What's a1clock?
I noticed that when using SetCPU and setting the minimum CPU speed to 245mhz, it seems like the CPU doesnt clock down to 245, but instead stays at 998. By setting the minimum to 328, it works.
Where can u see that?

I agree...where are all you guys/gals seeing/getting information like that off of the phone. What are the apps needed to monitor that information.
Also, exactly what is the stock CPU settings?

I noticed something similar.
When setting it to 998/245 and hit refresh 5 or 6 times you'll never see something under 998 at the top.
When setting min to something else than 245 but keeping 998 for max and hitting refresh 5 or 6 times you'll see the min value a few times when refreshing.
####################
where is the difference between on demand, user space and performance and what did you take? I took performace for some weeks and just set it to on demand (and 998/245)
so what settings would be proper to set to see a difference?

Overclock Question

I am using the Clemsyn Kernel now, but have never done any overclocking before.
What is the effect on battery life if I went to around 1.4ish?
What is the effect on the lifetime usage of my unit if I overclock?
After I download SetCpu, what settings do I use? Do I have to change anything in voltage?
I read something where people sometimes underclock when the screen is turned off. How can I do this?
Thanks for any help. I am a noob when it comes to overclocking.

Start off by setting your main profile to 1.4GHz and tick set on boot. And theres your overclock... I think interactive gov. is the most useful, you can try others if you want.
If you would like to limit the speed when screen off, add a profile under profiles select screen off and set your wanted frequency when screen off.

+1 This is exactly what I've done
If you set the max speed to 1.4 GHz and set the governor to performance it will drain the battery faster than if you had it set to the others. You'll most likely have already upgraded the TF by the time it dies due to overclocking. It does shorten the life, not dramatically though. You can set up underclocking in profiles.

[CM12.1/AICP] Tuning Battery Life on N900

Tuning Battery Life on Samsung Note 3 N900
I don't have a device anymore, but I still wish to share my experience and how I achieved 6 hours SoT with my typical daily usage on this phone.
This guide is for CM12.1 / AICP 10.0 (I recommend latter, it's the same CM 12.1 but with more options).
You can try this settings on aurora/stock ROMs with respective custom kernel (Suemax).
First of all, you need a kernel with Synapse support. This section is for CM12.1/AICP only! Don't try to flash these kernels if you are on Aurora/Stock - you'll have bootloop!
-- Download Stock and DJMax81's V2 kernel from this post and Suemax kernel from this post.
-- Make a backup
-- Flash CM12.1-DJmax81-Kernel-Lite-V2.zip
-- Boot your phone once and open Camera app to ensure it works.
-- Reboot to recovery and flash CM12.1-SueMax-Kernel-V3-By-DJMAX81.zip dirty. No need to wipe cashes.
-- If you encounter issues, restore backup or flash CM12.1-Stock.zip to return to the stock CM12.1 kernel.
Now you can fine-tune your Exynos!
First, disable touchboost. It's some sort of cheating Samsung use to make it's touchwiz not so laggy. On stock Android you simply don't need it, even if you set max CPU to lowly 250 Mhz, Stock Android UX is still decently smooth.
How to do this: open Synapse, go to the QoS tab. There are many, many sliders to control boost in different situations. Slide every one of them to the left. Now you gave full control of your phone freq to the governor.
This setting alone gave me up to 1 hour of SoT when texting or browsing. Because these are not demanding tasks and there's no need for CPU freq to ramp up.
Second, set min GPU speed to 100 MHz. This will save some juice when idle. Go to GPU Control in settings and set the corresponding Min freq slider to 100 MHz, then apply (you need to push the Set GPU settings button and a tick at the right top). You can also adjust Max GPU freq to suit your gaming needs. The more max GPU speed, the better gaming perfomance will be and the worse battery life in games (600 MHz stock value).
Third, let's go to Kernel Adiutor and here are some profiles for you that I found best!
Max Performance profile: Use zzmoove governor, max CPU speed to 1900 MHz, and at advanced governor settings set disable_hotplugging to 1.
Exynos hotplugging has rather negative effect on battery life as I found from my tests, you should never use it. If you are reading this and on Stock/Aurora ROM: disable hotplugging. It makes your battery life worse! Here is the test on Snapdragon 801, on Exynos hotpluging would yield even worse results because CPU with less core active will spend more time on unefficient A15 cores.
Zzmoove is the smoothest and fastest governor I found that still uses all available frequencies wisely.
That's the profile one should use for heavy games (and also set max GPU speed to 720 MHz in Synapse if you need it).
Performance profile: Use Interactive governor and max CPU speed 1900 MHz.
Interactive governor proactively ramps CPU to high (but not highest freq) to ensure great smoothness and still yield not-that-bad battery life (I had usually 4 hours SoT with 2G). For better fine-tuning you can go to advanced governor settings and set hispeed_freq to something in the middle, 800 MHz for example (but not lower than 800). hispeed_freq setting is the intermediate cpu speed which governor uses when there's initial load on cpu.
Balanced profile: Change governor to Ondemand, max CPU speed is still 1900 MHz.
You shouldn't worry, with touchboost disabled it would rarely ramp up to max speed, most often sitting on energy-efficient A7 cores and sometimes ramping to 1200 of A15, going even higher only when needed - still gives you whole power of your device without restrictions. DJMax81 did great job tuning this governor to our needs. You still can set max CPU lower (to 1400 Mhz) if you wish to conserve battery more on this profile.
Power saving profile: Go to Synapse and enable a slight touchboost: on QoS tab set CPU freq touchboost level 1 to 800 MHz (only the first slider). Then in Kernel Adiutor change CPU governor to Interactive. Set Max CPU speed to 1400. Go to advanced governor settings and set hispeed_freq to 400 MHz.
These settings are doing two things:
1. When not in use (e.g. you are not touching your phone), your device will use ONLY energy-efficient A7 cluster. So max 1300 MHz (it shows 650 MHz in Kernel Adiutor because A7 cluster is showing it's real freq divided by 2) with four cores - a performance level of middle-ground MTK device. Most often the phone will use 800 MHz freq of A7 (that's 400 MHz setting of hispeed_freq - a division by 2, remember)
2. When you are using device (actively tapping), touchboost will switch your device to A15 cores (starting from 800 MHz - at this freq they consume roughly same amount of energy as 1300 MHz'd A7) and if needed, interactive governor will ramp the freq even some more - up to 1400 MHz. When there will be no load, freq will drop to the minimum and system will switch to A7 cluster until next time you use it.
Extreme Power Saving profile: Disable touchboost, CPU governor is Interactive. At advanced governor settings set hispeed_freq to 400 MHz.
This makes your phone use ONLY energy-efficient A7 cluster no matter what circumstances. No matter what max CPU freq is set, interactive governor can't switch from A7 cluster to A15 (maybe that's a bug, but we'll use it). You can set max CPU speed to 650 MHz for sure, didn't make a difference for me.
Yes, it may lag. Yes, games are not playable. But we don't paint your screen black and white at least. Movies are fine, texting is fine, browsing too, 1300 MHz of A7 are still quite good - it's like low-end phone but with 3 GB RAM and AMOLED. Combine it with lollipop powersaving mode and GPU powersave bias (set in Synapse, always clocks GPU at 100 MHz). And your phone will go on and on and on...

Kernel Adiutor doesn't make profiles to share. You have to manually set parameters and then save profile for your device. That's only the guide of parameters to use for your needs.
Thanks for sharing.
I'm using TOS (a Chinese rom) now, and I got excellent battery life. The phone is still smooth.
If you're strict with battery life, TOS is really worth trying.

is that rom based on cm or touch wiz? probably cm coz of u mentioned gapps. But spen is working is doubting me that is touchwiz. Also how big is that rom? and is it prerooted?
that battery pics that u showed r awesome!
is it stable to use in everyday?
any lags? and free ram available?
tnx ! cheers!

Based on Touch Wiz. In China google is blocked so there's no gapps.
The rom is already prerooted, you just need to open it in Manage(an app)-Permissons-Root access.
It's 905MB.
Now i'm using it everyday, it's quite stable and smooth. And games (e.g. Hearthstone) are playable.
I don't know how to install Xposed, it errors every time I want to flash it.
As for free ram, I don't know how to check it in this rom.
i want to know that if this kernel works on flyme rom

Hello sir.... I am using sumax v3 karnel with the settings you have mentioned in the thread. Everything is fine... Battery life is great... No problem of heating... Speed is ok but i have facing a problem.... MY PHONE FREEZES RANDOMLY ANY SOLUTION PLEASE HELP. IT FREEZES WHEN SCREEN IS OFF AND I HAVE TO RESTART MY PHONE. I AM USING CYANOGENMOD 12.1. PROBLEM OCCURS ONLY WHEN I USE SUMMAX KARNEL AND PRESCRIBED SETTINGS.
set cpu gov ondemand because its hard to wake up cores on extreme low freq when on sleep mode

Sir i have been already using ondemand governor but problem priciest i reflashed the rom and usesed with stock karnel for 2 days phone didn't freeze with stok karnel but as i flashed the karnel and set the given values it started freezing again... I want to use the karnel because everything is better than the stock one heating issue is major one with the rom but can be solved by the karnel but how to get rid of freezing problem.

Hello sir.... I am using sumax v3 karnel with the settings you have mentioned in the thread. Everything is fine... Battery life is great... No problem of heating... Speed is ok but i have facing a problem.... MY PHONE FREEZES RANDOMLY ANY SOLUTION PLEASE HELP. IT FREEZES WHEN SCREEN IS OFF AND I HAVE TO RESTART MY PHONE. I AM USING CYANOGENMOD 12.1. PROBLEM OCCURS ONLY WHEN I USE SUMMAX KARNEL AND PRESCRIBED SETTINGS.

Try to increase voltage slightly, +25 mV should be fine. Kernel Adiutor - CPU Voltage - Global at right top. It will not make any effect to battery life. If I remember correctly, Suemax kernel is a bit undervolted by default and if on most phones it's fine, on some it can make issues.

You can install it from Play Store, if you don't have one. On my ROM it was just built-in. Synapse should be built-in in kernel, you can update it from Play Store as usual.

Sir i have set cpu voltage +25 the problem have been solved by doing so but some time cpu voltage automatically increased and phone start lagging and freezing... Any solution sir.. Thanks in advance.

Hmm, can you tell some more about this? I don't even have a clue, how the voltage can be increased automatically and phone start to lagging from more voltage? Usually, it's the contrary: more voltage = more stability for overclock etc.

Sir i set the cpu voltage by +25. Phone didn't freeze but after a day it freezed again when i checked the cpu voltage after restarting the phone it was the default values i set it by +25 again. After 7-8 hours some apps like Es file Explorer, Whats app, uc browser stopped working (saying like whats app is not responding) i was unable to move some content from phone to sd card. Other functions like settings, dialer etc. Was working. Phone didn't connect to pc. Neither restarted nor power off (restarting and shutting down.) after restarting the cpu voltage was more then the default values. See screenshots sir

Really strange. What ROM do you use? And build date.

IMPORTANT: we need a bugFREE custom kernel that solves the 1689mhz bug!

i have the 1689mhz bug!!! at random time the MIN freq of the cpu is stuck at 1689mhz andthe max still at 2ghz. ( you can activate on developer options the "show cpu info" toggle)
i cannot change the min value from kernel adiutor, i click on 652mhz but nothing changes, only a REBOOT actually fix the min freq used.
i thought it was a problem of my custom rom resurrection 5.8.3 or the fact i am using kernel adiutor, in fact this app does randomly give CPU LOAD BUG on several devices i mod! sometimes kernel adiutor load my cpu cores at 100% also on light load, but just forceclosing the app the cores return to lower freq.
but the 1689mhz bug is a KERNEL BUG, i read about this bug also on people with stock rom, and the p2a42 phone.... and i have p2c72 hardware phone!!! so this kernel BUG is found in EVERY VERSION of this phone.
please developers, we need a modded kernel that fixes this bug, and why not.......... new i/o schedulers and governors.... and maybe a little undervolt for every cpu freq

Haha! Have very less hopes,bcoz some feel that custom kernels are not at all needed! They think that a device wid 2ghz processor doesn't need custom kernel
And btw the post topic is 100% right,bt the place where it's posted is wrong! This should be under discussion section

Yes, thats true. The bug is i think VDD related. Sometimes the VDD switches automatically on, the min CPU freq goes up to 1689 MHz, and can not be lowered until you don't switch off the VDD. You can switch off in Kernel Adiutor/Thermal section, or use the following command :
echo '0' > /sys/module/msm_thermal/vdd_restriction/enabled
I use the KSLABS Schedule! app to run the command every 5 minutes.
I hope this will help you, until we get one bugfree kernel.
u are right
now the bug is MORE AGGRESSIVE THAN EVER............ i rebooted, i attachedthe phone to a charger, arrived 100%, then rest for 1h30min on idle(deep sleep) but when i started using the phone... i checked the frequencies and BOOM....... another time the bug of 1689mhz!!! the battery was 100%......
maybe there is an app that causes this... but which one?

Which ROM do you use?
I have stock 244, but the method worked for me in 233 too. In the past, I used the Magisk Crossbreeder Lite module to eliminate this problem, but the latest (1.6+) versions made the phone very slow, especially booting.

Maybe the Kernel adiutor itself cause the high load, as background task make 28-30% cpu load, see the attachment.
But, the 1689 MHz bug still exist. :-\

what app do you use to see the % of cpu for each thread?
i don't think that the cause is kernel adiutor... i repeat, a lot of people with 100% stock rom have this bug.....
hey vis could you help me with the string of the scheduler app? i don't understand how to set every 1 hour my previous screenshot i think is wrong because it does not work every 1 h
sorry but the "cron expression" is too much difficult to me to understand.....
EDIT i found how to do every 1h!! 0 0 0/1 1/1 * ? *
thanks to this site!!! http://www.cronmaker.com/

The app name is 3C Toolbox Pro.
Yes the bug is still here, Kernel Adiutor is only different problem.
After reading all your discussion.. I understood that one of you knew solution to stop the bug ,and the other guy learnt how to do it ..
But I don't get a single thing ,what and how you solved that bug
Note : I don't even know that 1698 bug is present , all I know is cpu idle is consuming more power ..
Is this the same thing you guys were discussing?
If yes ..how can a I solve it ? Any walkthrough?for dumb minds like me ...?

I've made the following observations:
On a fresh install(stock or custom rom(i have not tried Firelord versions)), rooted phone(with Magisk or SuperSU), if you install the Kernel Adiutor, and go to Thermal section the VDD restriction by default is OFF. You can change freely the CPU minimum frequency.
After some hours/days(total random) something switch ON the VDD restriction, the CPU minimun frequency going up to 1698 MHz, and unable to set back the default 652 MHz. If you switch off the screen the cores going to deep sleep, but if you switch on the screen the min. freq. is still 1698 MHZ.
If you manually switch OFF the VDD restriction, the CPU working normal, until switched ON automatically again.
If your phone is not rooted, the only thing what you can notice that the battery is dropping faster than usual, or the phone a bit warmer.
The problem still occurs even if you do not have a program that you can turn on/off the VDD.
The above solution does not repair the problem, it only remedies the symptoms...
I sometimes notice that even though I don't use it, "Google Play Services" consume an unusual amount of battery and will continue to do so unless I reboot the phone. I have never investigated the cause. Might this be related to the 1698MHz bug ?

I do not think so, but check the status of VDD when you have rooted phone. Sometimes I have too huge battery usage caused by the Google Play Services, but i would suspect first of the Location services. If I use some sport tracker, or navigation app then growing for me the Google Play Services consumption.

My phone is rooted. I will start monitoring VDD. FYI, I don't use any google app (Gmail, Play Store, Maps, etc ...). Location services is also turned off. Sometimes, out of nowhere, I'd see Google Play Services at the top of the battery consumption details. Yesterday, it had a very high CPU consumption time of around 1h (prevented the phone from going to sleep; had 3000+ wakelocks). I had to reboot the phone to get it to stop eating my battery. Usually, Google Play Services use the CPU for a total of 10min on a full charge.

If you don't use it, you can remove what is mentioned on the MicroG Prerequisites page[0].
Some apps nag about it but the only noticable problem I have is messenger lite notifications don't go automaticaly away after replying. Even my banking app keeps working.

gpu frequency

Hi. My xzp's gpu frequency 257-710 but every time stuck 257.I have never seen changed before. I tried cpu-z, cpu float, aida64 and devcheck. Device without root.how can ı see real time values on app or etc. Thanks.

You can use trepn profiler ( qualcomm) and use 3d bench to push the gpu.

If the GPU doesn't need to use all the strength that he have he will not use all the GPU frequency
It works like this:
System automatically detects whether heavy gpu usage is needed or not (for example game started) if yes then gpu frequency goes up to max and stays there until it needs to throttle its speed to some degree due to thermal reasons. If not needed (for example navigating in system, regular, not game apps) gpu frequency goes down to save battery as it is not needed to use high clock to render standard graphics (2d fonts and layouts). Sometimes it goes up a bit in case of different animations used like live wallpapers.
This is why it is recommended to turn off live wallpaper for those who want to utilize battrry life to maximum.
I hope now you understand why you can see lower cpu / gpu clocks in apps like cpu-z / gpu-z as it shows the current cpu clock where for you it shows IDLE state of cpu and gpu.
Solved. Games cant force the gpu ?
