I am currently on xiaomi.eu rom. Through kernel auditor app or any other app whenever i go to cpu section. It shows a min frequency which is always 652Mhz But max cpu frequency is somtimes set to 1843Mhz or sometimes 1958Mhz or sometimes even 1689Mhz. when i try to change max cpu frequency to 2016Mhz it again resets to its previous lower frequency in an insatant which means it dont want to set it to 2016Mhz. I thought it may be throttling down due to cpu temp but device tem is mostly between 37-41•C. Is this a mechanism to save battery or it is only problem with my device. Will it affect my max gaming performance.
please give me a solution.
That's the way the MIUI Kernel keeps the device cool and usable. I can confirm this behaviour. If you use a custom ROM your device will likely overheat when under heavy load because it is not limiting the max frequency resulting in a loss of mobile network @ about 44°C. Unfortunately no custom ROM does the same, that's why I stay on MIUI. And yes, you'd have a better gaming experience but I don't know if this will affect the lifespan of your device because of the heating issue.

thankyou for your reply. But if cpu frequency is lowered how my gaming experience wont be affected i.e. on heavy games.
By the way what is your normal cpu temp most of the time.

No, I am saying that your gaming experience WILL be affected. How much I don't know because there are still factors like GPU clock, network behaviour etc. Network however will be affected, too, as discussed in another thread here on XDA. You are going to have lag after a while. So this device is definitely not designed for the gamers.
Temps are same as you have. On LineageOS I had above 44°C while using Google maps for example. I lost mobile network then until the device had a chance to cool down.

hey guys i install custom karnel on my xpera mini...now i can overclock up to 2 ghz..i just wanted to know pros and cons of overclocking..
pros- increased speed and less lagging,
cons- short battery time, increased temprature.
Is it possible to underclock it to get more battery or shelf life from the phone?
we can overclock and underclock if we install custom karnel..

Overclock will give you temporary boosts and lets you to showoff, and to get super high benchmark scores , but its not for regular use
Overclocking reduces battery performance and increases heating of device, which might cause your device to get unstable
and of course high temp = bad for the hardware so be careful
My SE mini works very well at 1610 Mhz.No crash,no instability but I use high frequency for max 2-3 hours or when I want to play without lagging
Pros
Immensely fast speed
Massive score on Quadrant
No lag or crashes
Cons
Battery life goes down fast
Phone temp goes up - Massive problem
Phone might get bricked if the phone gets unstable (Happened to my friend)
I only overclock my phone whenever I play games or need to switch between apps constantly. Though I always keep on 1024 as that is the default setting
Recently I overclocked to 2ghz was chkin stability and gosh I burned my battery, its workin but fone keeps restarting n I had to buy new one!! Dis is d con
Pro: faster n better performance!!
Overclock can cuz serious damage too!! But its fine to showoff a lil but in controlled envionment for a short tym!

Overclocking is not actually advisable because there are chances that it will affect your phone and might screw it up in the long run .
Battery drain is inevitable and you will experience it .
Phone will heat up
It may not be good for the other internal components because of the over heat-unlike computers a mobile is not actually equipped with much of cooling system.
There is a good reason why the manufacturer has set a clock speed ,otherwise isn't it better for them to just overclock a phone and sell it for a higher price ?
People who design the custom kernels are just telling the maximum possible value they could overclock to.
Pros-
Bigger numbers
Little more faster performance
it recommended to not overclock always..just overclock when you really need it..
What are peoples thoughts on a modest overclock to bring me back up to the performance I am used to?
Say taking an ACTIVE up to 1300 or so.
With these new NON-OC kernels, are they undervolted? I have seen claims of absolutely massive battery life and I'm reasonably sure some of those were using cpu throttling and an overclock.
So confused at this point. Also heard some of the newer ACTIVE handsets cannot even be rooted.

As in most things if you not overdo it you can enjoy the benefits of better performance without risking your phone.My xperia mini is running up to 1200 (1024 stock). Also minimum speed 122 instead of 245.So better performance when you need it and lower consumption when phone is sleeping.Overall i got the same battery life, 2-3 days as with stock rom.The best thing to do is get an app that lets you make profiles.Like when screen is off min cpu 122 - max cpu 384 etc...
I don't know about these new kernels you're talking about but cpu throttling is something stock kernels do also (if by cpu throttling you mean cpu speed adjustment)
What settings are best for optimal performance and battery life? I don't have any experience with this, and I don't want to screw anything up. I just got tired of my games always lagging, but I don't want a battery drainer. I dont believe I have a custom ROM. Thanks for any and all help.

SetCPU probably won't work very well unless you flash a custom KERNEL. You can mess around with it if you like and you'll probably won't mess things up. One thing I discovered before custom kernels came out is that you can enable the second core by enabling profiles in setcpu. YOu can see that in the menu option of setcpu for "cpu". That may help you in your games. If you set max at 1500 and min 192 initially, you'll see that next time you start setcpu, the max and min are both at 1500. I used another app like cpu monitor widget to see what was happening and low and behold the cpu was scaling 'properly', so I left the setting in setcpu at 1500 and 1500.
In the end...it doesn't work quite the way it was designed for and even with custom kernels we're seeing some issues with it, but mess with it, you may find that enabling the 2nd core will produce less laggy games. You'll have to judge the affect on battery.

Hi there to all!!! I've been flashing various Android Roms for a few yrs now & really enjoy trying out new custom roms etc... Now i have a weird problem, Most customs Roms I have tried for my S3 i9300 are great & most 4.3 Roms come with a Custom Kernel such as Beoffla, GoogyMax, devil kernel & so on.... Now the problem is when leaving the CPU at defualt governer & settings everything is fine eg: min 200 & max 1400 but games lag now & again, When setting the CPU min & Max settings to 1400MHz, the results are much better but not for long, The CPU always drops to 800MHz when gaming as i notice the lagg, I've noticed this same thing with just about every kernel & rom ive tried wether its set to 1400 or even overclocked to 1500 or 1600max, I've also tried every trick to make them settings stick , like trickster mod etc, none seem to work for long, its like another system service is interfering with the settings or so.....im pulling my hair out to figure out what this is, I just want the CPU min & max to stay firmly at 1400Mhz or 1500 etc....without changing at all!!!
Any help or suggestions would be really appreciated.... FlashJunkie83

CPU/GPU can under-perform if they get too hot from playing resource-intensive games or apps. Maybe this is the issue.

hey yea would make sense but when running rooted stock 4.1.2 with stock kernel, this doesnt happen at all, i can set performance governer in set cpu & it stays at 1400 Mhz throughout, also i would of thought a Cpu thats ment to run at 1400 would be fine to do so all the time as its ment to be able to... even with a little heat behind it... its still only doing what its ment to lol, i remember in the days of my s2, i could push the cpu to 1200mhz & it would happily stay there even tho it got hot lol, im really sure its a system thing that upsets the cpu frequency, other than that there must be a way to stop the cpu/gpu from under-performing with a little heat..... thanks for reply tho dude....

@FlashJunkie83
- High temp will always cause freq throttling since this is how devices are designed. This over-rides whatever the max freq the cpu was designed to run on.
- try undervolting from the boefla config app (if you use the boefla kernel). I use -25mV with almost no difference to performance. Some users have gone on to -50mV but that gave me random freezes and massive lags sometimes.
- Test different governors. I mostly use the default pegasusq and it works well enough. Constantly high freq can affect the CPU in the long-term. So I use max freq of 800mhz and increase it to 1400mhz only when I play games.
- I'm not a fan of SetCPU. It's a great app but i find specific apps (like boeffla config) for kernels to be more precise.
- You can also try a different battery and borrow one from a friend to test it out. I had slight heating issues long ago and changing the battery reduced the heat for me somehow. It was not much, but it was enough for me to notice.

finally fiqured it out, it seems that cynogenmod has a diffrent approach to thermal throttling as ive flashed CM10.2.0 Android 4.3.1 along with Boeffla 2.1 for CM & the issue seems to have gone completely, have been running a performance test on games for best part of the day at 1600MHz with 4 enabled cores & just going back to normal settings for normal daily use, & not 1 issue with throttling, so now im very happy with the smoothness in games although its gets warm, but most high performance CPU's do anyways,So ive come to the conclusion that thermal throttling must be handled more by sammy roms it seems, but got the result i wanted in the end, thanks for all replies tho guys

Hello folks!
This thread is intended for sharing, please be kind. Any suggestions would be appreciated
A few days ago I was tired of having my Mi3 running on stock global dev MIUI 8, it was inefficient system with really bad memory management. On my experience, the MIUI tend to run out of memory. In some case, after a few hours of usage the system cannot reclaim the occupied RAM, thus making the system lags a lot and generate excessive heat!
Yes, MIUI is a feature-rich ROM, and the Mi ecosystem is a pretty mature ecosystem. However, those all greatness needs a lot of power to run on our 3 year old device. After a few research I decided to switch to CM13 ROM.
With efficiency in mind, I do my research and tinkering with my device to get the best setup possible without losing performance. The results are AMAZING! I can use my phone for a whole day without recharge in the mid day. All of this with huge improvement on performance, Real Racing 3 highest graphic setting without any noticeable lag! CPU and battery temperature are now significantly lower (43-47C idle / light tasks, 55-57C heavy gaming). Now that I've found the best setup, I want to share it with you folks! Here we go:
Mi3W 64GB
CM13 ROM snapshot build
CM kernel (automatically flashed while flashing CM13 zip through TWRP)
Screen resolution changed to 720x1280 use this guide
Modded interactive CPU governor (see screenshot below)
Undervolt (see screenshot below, this one really helps reduce CPU working temperature)
Noop I/O scheduler
Reduce aggresiveness of LMK (see screenshot below)
Thats all folks, hope this guide will get our Mi3 having another year of flagship-grade experience! Cheers! :highfive:

It depends on the kernel used. Cm kernel that he used supports undervolt. Careful when undervolting though as too much of it can cause cpu instability and reboots.

Yes, it depends on the kernel used. Some kernel support undervolting while others don't. You need to flash kernel that support undervolt.

While testing CPU voltage value, don't tick "apply on boot" option until you find the most stable voltage without causing system reboot or crashes. Every CPU has different limit on how far you can undervolt, but you can use the values on my screenshot as guidance (Snapdragon 801 / MSM8974-AB only)
Wow!! Thanks a lot bro. I'll fiddle now with my phone.

Undervolting (and clock adjustment, in general) pretty much is a case-per-case basis, so different handsets (even if it's the same type of device) may have different setup. Try lowering it first incrementally and test it, until you have it stable enough.

Ok thanks i will test it later
Recently found out that the prime core shuts off or throttles heavily at >~43C which often led to stutters & lags in heavy games like PUBG.
So was trying to search a solution for this problem & think may have got it finally!
1) On any custom kernel for MiUI go to your preferred kernel tuner app which has the options to change thermal profiles. I prefer Franco Kernel Manager.
2) Out of the 12 or 13 available profiles first select "PUBG"
3) Then again open the menu and select "Not Set"
*often the profile is not getting automatically set by the OS during gaming*
Here's a screenshot of 3DMark Api Overhead benchmark, note the drastic increase in the Opengl score.
Similar findings in all other benchmarks!
EDIT: It's more applicable in the situations when chip temperature is 38C+ and even a 5-10 min of moderate to heavy load makes it throttle or even shut down cores via Xiaomi's thermal policies.
So profiles like Dynamic/Not Set/PUBG help increase the threshold and allow high sustained performance for a long time..
Help even more in conjunction with the Game Turbo app as in my benchmarks like CPU throttling test it gives a better result with it on than off..
IMO more important than just high scores, this allows for less throttling & jank = sustained performance = unlocking the true performance of the SD855 just like in the OP7t.
Do try this if you've experience lags & throttling too & post your results!
Tbh I think it must be something else that is affecting your score. I just did the test 2 times and i get
OpenGL: 175 850
Vulkan: 571 914
but when I check at the bottom the CPU Clock and Temperature, I see that my CPU never went above 30C.

So 175k is quite less then indicating the chip is not running at a high speed at all.
Check this out- 400k+ with my settings

Again you must have changed something else. My CPU never went to 30C during the benchmark so i'm not having thermal throttle.

What you're saying - not getting above 30C is not the same as not being throttled in fact that's the point I'm making. The default profile is quite conservative & doesn't let the cpu run at its max potential. Thermal throttling does not necessarily have to happen at like 50C+.... but can be whatever the minimum threshold set in the default profile. So I've noticed that at 34-35C too the Prime Core will downclock from 2.8Ghz to 2.6Ghz & later on to 2.0Ghz/1.6Ghz & then just shut off at ~40-43C.
My scores are higher thus indicating more performance because of the cpu being allowed to run to it's original potential without the usual aggressive throttling.
You're getting 150k+ = throttled scores., I'm getting 350-400k+ because of using a different thermal profile... which again is just one of the many other inbuilt ones supplied by Xiaomi themselves.
So getting superb performance + Temps remain like 53C in games on the cpu, but the phone itself feels just mildly warm like usual.

That is weird, this is what i get on Xiaomi EU 20.2.27 on immensity and not setting anything on the thermal profile configuration. I however, underclocked it to 2.2ghz max and my environmental temperature is about 35 degrees Celsius.
Are you running any custom kernels or sort?

Vulkan - 760k

Woah! What's this blackmagic fkery? :laugh:
These scores are off the charts!
When I was on immensity could get only 445k-454k in Antutu & apioverhead (Opengl=250k, vulkan 500k) , 3dmark=5900
Btw You said 35C but the temps in 3DMark are showing even more low for you in ~23C something...and in the antutu graph too it starts from 29C ..so was it a typo, the 35C?
This is amazing dude!
& No, not on custom but I'm on MiUI 11.0.3IN version.
Overall I believe that due to the low temps in your case the cpu isn't throttled at all & able to sustain max speeds for a very long time.. A very temperature sensitive chip, low threshold levels set by Xiaomi

Hmm I think it might be due to the fact that I underclocked the CPU to a maximum of 2.2ghz maybe. And no, 35 degrees Celsius is my environment temperature, not the phone chipset or battery's temperature haha. I only ran those test once and uploaded the result, who knows if I might be able to get higher scores?
Actually if you looked around, someone posted a snapshot of 510k on Antutu before. I recalled it's in the Quad kernel telegram group.

Ok, try this - first set evaluation profile. Then again select Not Set after that & exit the app.

To make fingerprint work again you need to reflash Magisk after the kernel.:good:

I'll try it today.
But guessing that it'll be more or less the same as there's no CPU OC possible on the 855 atm & geekbench usually doesn't throttle in the first run enough to make this tweak help it any more.
It's more applicable in the situations when chip temperature is 38C+ and even a 5-10 min of moderate to heavy load makes it throttle or even shut down cores via Xiaomi's thermal policies.

Getting 509k for opengl here Highest achieved on antutu with 11.0.5 and immensity gets me about 510k. Try to make sure your thermal config is not set or disabled
