This will likely be a controversial topic, but I'm going to risk it.
Also note that this is not meant to be a jab at kernel developers, or an attempt to lick CM developers' balls.
I have just been thinking. Custom kernels often claim an improvement in battery life or performance with their kernels. With Samsung ROMs, this is believable. The case of the fuel_alerted bug not being fixed with Samsung ROMs is an example that Samsung kernels aren't the best.
However, with Cyanogenmod ROMs you would think that the developers of CM would know best, since they *probably* work far more intimately with the code than custom kernel developers. Has anyone found an improvement in battery life with a custom kernel as compared to the stock CM kernel?
Now, I'm aware that custom kernels offer some features not found in the stock CM kernel, like how dual-booting is available for Siyah. But let's focus on battery life and performance for now.
Again, this is not meant to be a flaming thread. I genuinely wish for a conducive discussion on this topic. Lastly let me express my appreciation for both CM and Kernel developers, for devoting their own free time for our sakes.
Thanks!
I'm not sure if this is what you are looking for as an answer but a tweak i've used to give better battery performance is CPU FREQ_MIN. This is the frequency below which the 2nd core is not used. I don't believe you'd be able to use this tweak without a custom Kernel

It helps, thanks Personally I would prefer to try to quantify battery life with different kernels myself. Most phone review sites choose to test battery life by looping a video, however I do not believe this accurately measures battery life.
If anyone knows of an app that loops web browsing I will be happy to test it for myself.
I don't even care for extra 10 minutes battery life. If you want extra battery life don't use the phone. Lol.

But I bought the phone so that I can use it right?
I was looking to flash a new kernel for my poco f1.
I search for a bit and find out that people consider those 2 the best one out there
Can someone explain me which one is better and why?
Sphinx has better performance but runs hotter than Franco this is because Sphinxes clocks are higher.
Franco has lower clocks so you will see minor stutters in games but it is clocked lower than stock. While only francos gpu is overclocked.
Both are stable in all applications no crashing.
it's not overclocked on franco. and it's a bad idea to overclock when it throttles anyway at load. it will make things worse. you could actually get better performance if you underclock...

so in your opinion which one is better for battery life?
I'LL go for franco anytime.. of the day.. both are superb in performance.. but im getting longer battery life with franco.
Franco is a great developer, buy he doenst use f1, just develop for it. Sphynx is an f1 user and his kernel is better polished, i have better battey with it. But there are lots of good kernels here, now im using shadow kernel, it is very good too
kernels don't really matter for battery life. unless using drivers with issues, which isn't a problem on a poco.
if you're using miui, debloat services and processes that constantly report to miui and wake your device.
limit apps push notification and background access. disable sync of non essential services.
personally i don't believe in using battery saving profiles and tweaks like LKT and messing with CPU governers and I/O scheds, but you can experiment with those if you need more battery at the expense of performance.
also try to optimize battery for any service/app you don't need realtime sync for (or don't need it to stay running in background). can also try the google play services gms doze module.
use adblocking browser like Bromite / hosts file to prevent ads from loading will also help battery times.
all of these have far greater effect on battery than kernel level tweaks or differences.
To be honest, the kernels I love are not the two. I actually use Shadow and Twisted Prime. I am currently using Twisted's kernel because, in my use-case, it actually provided me with better performance and overall battery. However, Shadow kernel is also good because you can add tweaks that will make it even better.
After being with franco kernel for quite a while.. im.now.trying the MALAKAS or MLX kernel.. and im telling you bro.. this one's damn smooth and effficient too.. wow. Just wow..

Lol are you in dreams ?
Franco is the most power hungry kernel.
Evel the stock is better than it.
Without using any underclocking.
And after underclocking it gets like 2+ minutes in battery life and makes the phone's performance ****

What kind of tweaks..
Just wanna report that Twisted is the most balanced kernel that I've tried.
Sphinx kernel has a better performance than Franco, but the device will be hotter. If you're in a tropical country, the temperature may stay between 40°C-45°C in Sphinx. Franco saves a lot more battery, also low temperature, but I don't like the performance in games, but it is better than the stock kernel.

What is this? Some sort of competition? Ask your question in a more appropriate way whether you want better performance or better battery life. Both kernel serves different purpose.

That's quite the opposite. Francisco owns a Poco F1. Infact he was provided the unit by Xiaomi, afaik. On the other hand, Michael doesn't have a Poco F1. He owns a Dipper (Mi8) which share similar hardware and software with Poco F1.
So I just unlocked the bootloader of my one-week-old Poco F1, flashed LineageOS 16, and everything has been smooth sailing so far. Now, I want to flash a custom kernel. What can you recommend for a good balance of battery life and performance? I'm not really keen on tweaking parameters so I want a flash-and-forget-it solution. Thanks in advance.
Sphinx works best for miui and lineage.
Franco is also up there
Canting kernel. At first I was flashing a different kernel daily. I found Canting and have been on it for nearly a week. Super stable. Not 1 random reboot or freeze and it also has vibration control, sound control, display control, Klaspe and just about everything else
https://github.com/khusika/canting_kernel_xiaomi_sdm845/releases
Sphinx Kernel is a good all-rounder, if you want a 'leaner' kernel go for Simple Kernel. As for performance, I've heard quite some praise from Malakas Kernel but I can't guarantee anything. An honorable mention would be Canting Kernel.

Arter97 kernel is good for balanced performance and battery life and its very smooth

I use lineage stock and have been getting ~8 hours SOT with light usage, over 48 hours between charge. The gains/losses in performance and battery life between kernels were negligible for me in real world usage and sticking with stock is just one less thing for me to worry about when updating.

Yep, might as well stick with stock I guess. The development done into these kernels is very active that some even update every day. I think it's too much of a hassle to me to flash a newer version daily.
I also like to believe that wiping cache frequently, which is a prerequisite in flashing, hurts battery life, because the phone doesn't get to compile it and as a result, keeps on running background processes to rebuild it every time you do so. What do you think?
Go for FK. 8 hours sot while playing PoGo non stop on 4g. Very good performance and non heating issues so far.
Just wanted to update this post based on my findings:
Franco: Awesome battery life, though the device essentially becomes gimped. I'm not a fan of underclocking.
Malakas: Best performance by far, and also pretty good battery life. A bit unstable, though.
Sphinx: A good balance between performance and battery life, though idle drain is a bit high. Will test a bit more.
Not willing to test arter's since it's SELinux Permissive.

I'm running Evolution-X with the Optimus Drunk Kernel. I have the NVT panel version of the Pocofone and my experience has been excellent. I also service a FTS panel version of the Pocofone, that had the freezing problem, and the Optimus Drunk Kernel really helped turn the phone from a freezing/frustrating nightmare and a similar experience to the NVT panel version. I recommend both the Evolution-X ROM and the kernel. Currently, the default kernel on the ROM is the DERP kernel, which is also good.
Nowadays I just stick with the stock kernel
So yeah as the title says I can't decide between Sesh 69hz and Optimus drunk, currently using Evolve X no other custom kernel. I'm looking for best performance and battery life
i'd suggest NGK if you are in need of both battery backup and performance

Sesh is definitely designed for gamers and who love performance i m also using this kernel and yes this kernel not for who don't play games on mobile and want more battery. NGK is balanced which give u decent performance as well as good battery backup and optimus drunk is beast if u want more SOT this is my review after using these kernels and may be differ from other because everyone using their device differently and my device also 1 and half year old. So results are not same for everyone.
I agree with NG and Drunk kernels for SOT but for andro 10 there are some od changes and seems that, for me, Miui 11 with andro 10 stock gives such a good SOT that is maybe even better then other custom ones.
Malakas had awesome development but i do not know what happened to him. If anyone knows please say it.
Also a side question - How do i boost screen colours like Malakas had in his kernel?

Installed NGK in the end and for battery life on balanced is a fu**ing beast with stock miui at work i would lose about 25%-30% with heavy reddit usage and some cod mobile here and there but now it doesnt drop below 89%

Oh yes it seems to be crazy good. It comes as standard in HavocOS. Do you know where to find it?
Can anyone here tell me that which custom ROM is best for gaming and on the other hand which provides the most customization
All though I've never tried it I hear corvus os is the best for gaming
gaming roms doesn't exist and they never existed
corvus was never meant for gaming

In my experience you can definitely feel a difference between roms. Some are more smooth, some styles are more efficient for how i use my phone. There are factors to consider when choosing a rom. And I've seen a lot about gaming and corvus so that was my recommendation. Are you saying he shouldn't care what rom he plays games on because they are basically the same?

all roms use the same kernel so performance shouldn't change drastically. So he should choose a rom according to his tastes, not performance ... for that we have to wait for the custom kernels

Maybe one did.
MIUI has some turbo mod in the settings.
It could run the processor in peak performance mode.
So try this.
Actually, first, please define "Gaming ROM", since you're not even clearly understanding what is Gaming ROM, how can u ask for it? Besides, @alonsoj636 was right in one thing, whatever ROM u use, still sharing the same kernel ( until we have Custom Kernel too ), hence, the performance would be slightly different. But one thing that some ROM does have is Boosting Touch Sampling Rate, and that function does help your gaming experience more smoothly.
I am looking for something similar i don't why but the pubg performance in miui 12 is very bad i have 4,64 variant but frame drops are very annoying i guess the sd 678 is not yet optimised for gaming considering its a fairly new chipset introduced in phones
