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.

Im using zaiben rom on my lg optimus 4x hd. The performance is poor. Overall laggy and horrible gaming. I dont like using non stock based rom as they always have some bugs. I tried custom kernel like iodak werewolf but it made my phone heat up like crazy and unusable while charging. Any solution?
Buy another device stock Roms won't give you a good performance increase.

I used stock with zaiben kernel for months, uninstalled all the useless system apps with Root Uninstaller, including hangouts, gmail, maps, youtube ... and then installed them again as normal applications and used the greenefy to hibernate most applications, never had a problem of lagg or excess heat. Now I'm testing some KK ROMs , and do the same thing using iodak kernel 9.95 and I'm liking the results.
Make a bakcup and test some KK ROMs.

Believe me, if you're using an LG phone, custom ROMs are ALWAYS better.
Stock ROM got too many bugs and I don't really like modified stock ROMs as people usually add more bloatware.
You should really give CM11 a try.Latest nightlies got very good performance with iodak 9.5 kernel.And no important bugs you should worry about.

If you use a custom kernel like iodak or ww, you can tweak many parameters. Among them there is cpu clock frequency and voltage.
Personally, I've set the stock 1500 mhz frequency and undervolted Mpu and cpu respectively by -30 and -75 mV. My phone runs smooth as silk and never gets horribly hot.
The guys who replied before me are right, though, stock roms or their derivates cannot be compared with CM11 in terms of performance they are way better. If I were you, I would flash one of the latest nightly and a custom kernel.
After some trials and errors you will be able to find the correct balance between over/underclocking and undervolting.
That is, if you are willing of doing some experiments. If you are looking for pre-cooked solutions I am afraid you will be deceived.

Trickstermod is a favorite for most of the people.Check your tegra variant, if it's 1 or above, you can use -122mV for CPU with no problems, max freq set to 1.5 ghz
I'm using this for months now and I sometimes forget my phone can get hot, unless I do heavy gaming for 30 mins or more.
Also try to overclock GPU.Helps a lot with FPS issues.
If you want good battery life and decent performance, underclock to 1300 mhz and undervolt by -122mV (if your variant is 1 or above)
Btw you can check your variant via /sys/devices/system/cpu/cpu0/cpufreq/tegravariant after installing iodak kernel.Higher the variant, the higher you can overclock/undervolt.
@UP
My tegra variant is 3 o.o But when I undervolt 30mV on CPU and 75mV on MPU - as @peppethustra recommend in http://forum.xda-developers.com/showthread.php?t=2761923&page=2 - it causes freezes, even when I underclock to 1,3GHz :/

All phones are different you may have to tweak the values to fit your needs. Try upping the LP CPU voltage to -10 and work your way down. For MPU try -25 and work your way down on that as well.
Mine is a variant 2 and can use -20 and -110 with the 520 GPU overclock
Edit: also for more performance try changing your minfree values. Lower values mean better multitasking and high values mean more killing of background apps but more free ram for the foreground apps. I personally use 8, 12, 45, 65, 95, 165

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 +1000
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.

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.

OC more than possible
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.

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.
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.
