Hey guys! I just wanted to know which is the best kernel for cm 13 for a balance between performance and battery life?
Note: I know all the devs give their best output, but i wanted to know which is the best for a balance between the two.
Thanks.
It is a subjective personal opinion. We can't say for sure.
Boeffla thoroughly tests his kernels before releasing to make sure they match his quality standards, its a great balanced kernel.
Black.Reactor has up streamed our Primitive kernel and gives a great battery.
Arsenic is a good stable balanced kernel.
Starkiller/Practical enables the user to control every aspect easily.
It all comes down to your personal usage.
Well said Josh! Couldn't of explained it better

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?
What ROM you guys can say has the best battery life?? Ive used some of them and the only thing i can say is that the older builds with 2.2 have the best battery life, but i want to have a newer build on my phone cause of the new features and stuff, but if you guys can tell me which one of the new builds have the best battery life???
Things like battery life and performance are highly device dependant. Although many users may report great battery life on a particular rom, you may not experience the same effects. Hardware is not created equally, and as such, nobody can give you better advice on what's best for your device than yourself. I'd suggest find some roms that are reported to have decent battery life and test them for yourself. Same thing with kernels. You might experience awesome results with a particular rom/kernel combo that someone else might not. Test test test. Get to know your device.

NOTE: This is not the usual "what is the best ROM?" thread. This is a collection of personal opinions of gamers like myself to find out what current ROM works best for you and is not based on just a benchmark number. Please include your reason why and any relevant information that you would like to include.
Viper 3D
I am not absolutely sure, but when I experimented with Viper 3D ROM from Team Venom (here: http://forum.xda-developers.com/showthread.php?t=1991150 ), when I was reading through the thread, I saw someone said that it is the best ROM in case of gaming performance. Compared with Galaxy S3 than on Evo he had better results in FPS than on S3. So I don't know if this will help you somehow, but you should give it a try.
Can't say for sure either, but I've been trying a couple of Roms. More than the Rom, the Kernel seems to make a difference for Games.
Anyhow, I found to get really good results with the Sensai Rom when I use the Buttered Toast Kernel @1566mhz. You can save your battery and not overclock the GPU as that really didn't ever result in much performance increase.
I believe I had the best experience with the infamous Anthrax Kernel, though it was also draining battery like a hog and wouldn't run quite as stable as the Buttered Toast Kernel does. Either way, I'd say mostly stick to the Rom you like in terms of Featureset and try switching through Kernels, that's what mostly game me the biggest performance gains. (My personal favourite: Buttered Toast)
OK, I realize that everyone has a different idea of the best ROM and/or kernel, and I fully expect to try out a few different ones to see which is best for me. However, I am hoping that I won't be irritating anyone by asking for suggestions on where to start. I don't need a lot of extra features, but I do like to be able to configure as many settings as possible--that is the main reason I chose Android in the first place. I also want to maximize battery life. Based on my experience with SlimBean on the Nexus S, it and SlimKat will be definite contenders, but which others should I consider? And are there any specific kernels I should look at? It will be a couple of weeks before my LGOG arrives, so there should be fairly stable 4.4.2 based ROMs by then, but I don't mind using 4.3 ROMs if they will provide better performance. I have been using a Galaxy S II for the last several months, where NeatROM is the only real choice if you want good battery life, so I'm a bit out of the loop.
I have been having a similar issue with trying to maximize performance and battery life at the same time. I have found that using android 4.3 really does make a huge difference in battery life and it makes all the animations, I think, look more fluid. Now as Kernels go, I cannot recomend one in particular, but look for one with eco mode or just change your processor setting with Trickster mod. I use only 2 cores, the ondemand governor, and keep my frequencies between 1026000 and 1512000. Hopefully this helps.
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
Sphinx Kernel

Yes. 3x each test averaged with unthermal to rule out throttling.

Awesome! What do you personally recommend for the best balance of battery life and performance without tweaking? How about pure battery life?

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
