[REQUEST] Stock Kernel with KCAL? - OnePlus 2 Q&A, Help & Troubleshooting

Hi, this is a friendly request for the senior devs on this forum. I am actually a noob when it comes to kernel compilation. So I wanted to ask if anyone here has already compiled or is willing to compile the latest stock kernel (from 3.6.1) with no other features except kcal controls. Because me and other OP2 users feel that battery life is best on stock kernel but the washed out display is absolutely disgusting. Also if it's not possible just us know, thanks in advance!

Did you try boeffla's kernel? gives much better battery life than stock for me (1/3 longer, in any scenario i tested it).
If you still want to have stock kernel here are the kcal commits. just set up Virtualbox Ubuntu, set up build environment , download official op kernel source (the 6.0.0 version!) and cherry-pick the commits (google it).
If the effort is not worth it, use boeffla's or stock without Kcal.
I can try to help you if you're stuck, but mind that i'm just starting with compiling stuff myself.

Yeah man I have tried boeffla. Performance is okay but battery isn't as good as stock imho. Maybe my settings affected it. Can you tell me which version of boeffla you use and what settings so maybe I can replicate your results. Thanks man.

Sure, i use boeffla 2.4-beta5, interactive battery extreme governor (u can tweak max frequency on little to 1200mhz), set little cores (i use 2, you can set it to 3-4 for more performance) set big cores to min0, max0 (if you need power to play games etc. set to min0 max 1-2) GPU underclocked to 27mhz, boost disabled, governor adreno (or powersave, might gives lags)
Further i installed xposed, greenify, amplify (there is a free version, but u have to compile it by yourself--> easiest with android studio).
And i followed this thread to maximize my battery life.
Tried several rom and kernel combinations, with this setup i get a sot of 5-6h with 48h of not charging or 7-8h in less than 24h. But on Lineage 13 its even better... (trying to compile a custom oxygenos, debloated, without playstore, F2FS capable right now but not able to activate F2FS)
If you're interested in the ext4 image, tell me (its untested though).

Damn dude these settings sound a bit extreme doesn't your phone lag like hell lol. And oh hey that sounds really interesting! Is it based off 3.6.1? And what kernel have you implemented it with. Right now I'm testing HalogenOS (loving it so far) but when I feel like switching again I would love to try your build. Link me!

I don't even have microlags (with other kernels and this settings it lags like hell, idk why boeffla doesn't)
However, app opening speed and switching between apps is a bit slower than usual).
Idk what the official source's base is (i guess 3.5.8) as i could'nt boot it up yet. Kernel is original kernel (with F2FS activated by me), i'll change this when it boots with f2fs.
I'll send you the link when i have time

[Arrows - Guide] Best Aosp GB & ICS Roms [Updated - 1/22/12]

Feel Free to post and give feedback ^_^
Also feel free to Vote the thread ^_^
Q&A is in Post 2
_____________________________________
Hi Everyone, Arrow here and this is my guide to find what is the best aosp setup for your evo or android. It is true when people say "every phone is different." However there is an average of people that get similar results. At the moment people have different interest such as some people want performance and some want to improve their battery life. Of course certain people want both but only some get both.
*Remember what i put here is an average and may be different on your evo*
AOSP GB ROM'S: Ok so to start off, these are aosp roms still being updated as of now.
CyanogenMod 7 (CM7) - The most famous aosp rom out there, all or almost all other aosp roms are based off of this rom. This rom has a stable rom and experimental nightly builds. Anyone will tell you that you can't go wrong by choosing this rom. and believe me you will enjoy it.
CyanogenMod 7 Thread
Miui - This rom has the longest battery life and is very customizable. This rom is based off of CM7 and is an excelent rom. However unlike CM7 this rom does not have 4g so if you are willing to sacrifice 4g then believe me this is your rom.
Miui Thread
Gingerbread Evo Deck - Ok so although CM7 is amazing decks gb rom has said to be the exact same thing but giving off better battery life. other then that it is pretty much the same thing with some minor tweaks and some bloat ware removed.
Gingerbread-Evo-Deck's Thread
Xplod E4G - Team Nocturnal designed this rom and it is pretty much CM7 with the Sony Launcher + their apps. This rom will give your phone a nice cool feel that other people don't have. If you like a lot of eye candy then get this rom because it is CM7 just with a different look and feel.
Team Nocturnals Xplod E4G RLS1.2
teh roxxorz said:
using Xplod: there's a 50/50 chance the new tiamat kernels [4.0.7+] may not boot, in that case, they should use 3.3.7.

ICS(mod7) - Team Blaze designed this rom and you can consider this rom like Xplod E4G, a rom just like CM7 with some minor tweaks but with a different look and feel. None the less this rom has something very special this is the closest rom to being like ICS (Ice Cream Sandwich). I 100% support this rom because they are doing the best they can to make this rom look and run as smooth as ICS. so if you want to look like your ahead of the game definitely get this rom.
ICS(mod7) Thread
AOSP GB Kernels: These are three kernels that i know of, if you know of more please let me know and i will add them.
Tiamat 4.1.0 - This is the latest kernel made by Tiamat and this is the only aosp kernel still being updated. This kernel on average gives people great performance but lacks on battery life. The main Governor for this kernel is SmartassV2 which is a balanced governor, good to turn on your phone and good to use on a normal day to day bases. For this kernel i do recommend using this governor. It does have SBC and Non-SBC kernels. *Side Note* (Some people say Tiamat 3.3.7 works better for them and is also known as the LEE Kernel because it was awesome like Bruce Lee and looks like Lee backwards [337])
Tiamat Website I also put the Zips in the Attachment (At The Bottom)
Savaged-Zen - This kernel is no longer being updated, however it is still amazing this kernel seems to be Tiamat's competition. Where Tiamat lacks on battery Savaged-Zen does not. However it's performance is not as good as Tiamat. This Kernel comes in two version BFS (Brain F***ed Scheduler) and CFS (Completely Fair Scheduler). BFS is said to give better performance and CFS is the normal kernel. This kernel only comes with SBC however you may download "SVZ Manager" which will allow you to turn SBC on or off. The main governor for this kernel i believe is on demand However i use smartass and a lot of people us InteractiveX.
Savaged-Zen CFS sbc I also put the Zips in the Attachment (At The Bottom)
Savaged-Zen BFS sbc in attachments (At The Bottom)
SVZ Manager I also put the Zips in the Attachment (At The Bottom)
GoDm0de - This Kernel was made by toastcfh and is no longer being updated. It is non-sbc and in my opinion definitely the best non-sbc kernel. This Kernel has insane battery life and a pretty good performance. If you do not want to use an sbc kernel i recommend for you to 100% use this kernel. The Governor for this kernel is set on on demand (i think) however i got the best battery/performance using Interactive.
GoDm0dE Kernel I also put the Zips in the Attachment (At The Bottom)
AOSP ICS ROM'S:
ICS rom by: the_Plattypus and it is still in Alpha testing. however the development for this rom is moving really fast so hopefully a beta will come soon.
EVO 4g Ice Cream Sandwich from source
ICS-evo-deck: This Rom is by kushdeck, After testing out Decks ICS Pre-Alpha 4 & 7 rom i conclude that although it is a alpha it can easily be used as a day to day rom. extremely fast and very snappy. only thing that i found not working was the camera. (Now on Alpha5)
[ROM][ICS][1-11-12][WIP] ics-deck-evo [alpha5]
All Decks ICS Pre-Alphas
All Decks ICS Gapps
AOSP ICS Kernels:
Jaredthegreat ICS - jared has the most advanced ics rom which is in beta 2 but does not have a working camera to check this rom go here:
[ROM's] -ICS- 4.0.1-4.0.3>[AOSP]<--~B.2.0~
Will post them when they are released!!!
Rom Manager/Kernel Manager:
Rom Manager: This is an app from the android market and is extremely useful for pretty much anything. you can back up your rom, you may go into boot loader and you can check if certain roms such as "CM7 Nightlies" have been updated. However people do prefer Amon Ra for flashing, which is another plus of Rom Manager it allows you to flash alternative recovery, which will flash Amon Ra for you.
Kernel Manager: This app was working before but has stopped now, however if it does start working again what it had was pretty much all the kernels that you needed for any rom. this app would allow you to flash a new kernel immediately by going to the kernel you want to flash.
Reserved
Q&A:
Q: What is SBC?
A: SBC stands for super battery charger. SBC is trickle charging, It stops your battery from dropping from 100% to 90% right when you take it off the charger. Some say that it harms your battery but i haven't seen any harm and plus it only costs $5 to get a new battery on Amazon.
Q: How to set up and flash your roms and kernels?
A: well my friend "Crossrocker" made a guide for this with everything you need. so just click to go to his thread. [GUIDE||Oct/23]Best AOSP(CM7|Decks|MIUI) configuration.
Q: What is the difference between governors?
A: This Thread by "RJackson" explains it all:SetCPU governors (explained)
But if you're too lazy to click it here they are:
As explaind by RJackson:
ondemand - Available in most kernels, and the default governor in most kernels. When the CPU load reaches a certain point (see "up threshold" in Advanced Settings), ondemand will rapidly scale the CPU up to meet demand, then gradually scale the CPU down when it isn't needed. - SetCPU website
conservative - Available in some kernels. It is similar to the ondemand governor, but will scale the CPU up more gradually to better fit demand. Conservative provides a less responsive experience than ondemand, but can save battery. - SetCPU website
performance - Available in most kernels. It will keep the CPU running at the "max" set value at all times. This is a bit more efficient than simply setting "max" and "min" to the same value and using ondemand because the system will not waste resources scanning for the CPU load. This governor is recommended for stable benchmarking. - SetCPU website
powersave - Available in some kernels. It will keep the CPU running at the "min" set value at all times. - SetCPU website
userspace
A method for controlling the CPU speed that isn't currently used by SetCPU. For best results, do not use the userspace governor. - SetCPU website
Interactive - The 'interactive' governor has a different approach. Instead of sampling the cpu
at a specified rate, the governor will scale the cpu frequency up when coming
out of idle. When the cpu comes out of idle, a timer is configured to fire
within 1-2 ticks. If the cpu is 100% busy from exiting idle to when the timer
fires then we assume the cpu is underpowered and ramp to MAX speed.
If the cpu was not 100% busy, then the governor evaluates the cpu load over the
last 'min_sample_rate' (default 50000 uS) to determine the cpu speed to ramp down
to.
As explained by MDJ:
SMARTASS GOVERNOR - is based on the concept of the interactive governor.
I have always agreed that in theory the way interactive works - by taking over the idle loop - is very attractive. I have never managed to tweak it so it would behave decently in real life. Smartass is a complete rewrite of the code plus more. I think its a success. Performance is on par with the "old" minmax and I think smartass is a bit more responsive. Battery life is hard to quantify precisely but it does spend much more time at the lower frequencies.
Smartass will also cap the max frequency when sleeping to 245Mhz (or if your min frequency is higher than 245 - why?! - it will cap it to your min frequency). Lets take for example the 998/245 kernel, it will sleep at 245. No need for sleep profiles any more![/QUOTE]
As explained by teh roxxorz:
Lagfree - like the performance governor. It will scale the cpu to higher frequencies when needed, but not to 100% like performance, so you'll get a lil better battery out of it
SmartassV2 - A smarter smartass governor. Code was re-managed/removed to make it more optimized, and have better scaling performances
InteractiveX - a better interactive governor I believe; low scale cpu settings, for texting, browsing, ect, nothing intensive. I wouldn't use it for emulators, ect.
Q: Do you need PRL/Profile/Radio updates? Do you need to go back to sense based to do these still?
A: No you don't have to go back to sense to do these and you don't have to do these because Rom's will come with what you need. None the less if you would like to update your radios here is a thread by "Calkulin" where he keeps the latest radios updated: [ Radios ][ 9-5 ] All EVO Radio, WiMAX, PRI, NV & HBoot versions
Q: Does HDMI mirroring work on these roms?
A: As of this moment Miui and CM7 both have HDMI mirroring working, and sense all the other ones are cm7 with some tweaks they as well have HDMI working however from what i have read the only one that has not had problems with HDMI is Decks Gingerbread Rom
Q: Are all other major features (4G (except for Miui), bluetooth, front & rear camera, GPS, apps such as Netflix, Skype, Google Voice, Sprint Visual voicemail) all working at least as well as on a Sense or stock ROM?
A: Yes everything is working, however on CM7 and i presume on some others you also have to flash a gps fix which you can get from this thread: [GUIDE||Oct/23]Best AOSP(CM7|Decks|MIUI) configuration. and the Voicemail seems to have some issues for some people but works flawlessly on Decks with it's gapps + Voicemail which you may also get from this thread: [GUIDE||Oct/23]Best AOSP(CM7|Decks|MIUI) configuration.
Q:My wifi is connecting/disconnecting after a second, what should i do?
A: This answer was given to me by "teh roxxorz." This has nothing to do with your rom or kernel, do this:
Back up everything into Titanium Backup
Boot into recovery
wipe cache, Dalvik, and pretty much everything
reflash your rom,kernel and gapps (or if you would like to check out some other roms and kernels just click on the link in my sig)
once you've set up your phone download Titanium Backup from the market
in titanium backup restore all your apps ONLY!!! (don't get apps w/ data - only get apps, and do not get system data)
after this your wifi should be working just fine
Q: I am having wake issues?
A: Here is a Guide made by JBabey[FIX] Wake Issue (Android OS) - Combination of Radio/PRI/NV/Wimax/GPS !Solved!
Q: Can i make my 3g speed faster?
A: Yes, This answer was given to me by teh roxxorz:
You need to flash a sprint sense rom. I emphasize sprint because it won't work on the sense 3.5 roms, as they're all ports of other non sprint roms.
1. Flash sense rom
2. Obtain your msl, download msl reader from market, use it, write it down
3. type in ##3282# , input your msl (you can get this from the app msl reader)
4. Click edit mode > advanced
5. Scroll down to HHTD proxy port and address
6. Change the proxy port to 0 and proxychange the address to 0.0.0.
Q: How can I fix my GPS?
A: This answer was given to me by teh roxxorz:
- flash a sense rom
- open up the dialer
- Type ##GPSCLRX# or ##4772579#
- Your enter your MSL at the prompt
- Your phone will soon reboot > done
Q: Is there a guide like this but for sense roms?
A: Yes if you are looking for a sense guide rather than aosp then check out this thread by tropicalbrit
Q: What is your setup at the moment?
A: Rom - Decks 4.0.3 Pre-Alpha 7 ICS Rom
Kernel - Stock
Governor - Conservative
CPU Max/Min Frequency - 729/128
IncrediControl (app) - (-100) [I get to (-100) by first doing (-75) and leaving it there for 3 days and then I do another (-25)]

And any reason you were gona message me?

Hi,
Thanks for guide... I am considering changing from
my stock rooted ROM, so very timely for me!
Some features that you don't mention or summarize
that may help me and others.
PRL/Profile/Radio updates? I believe you need to
go back to sense based to do these still? [yuk]
HDMI mirroring?
Are all other major features (4G (except for Miui),
bluetooth, front & rear camera, GPS, apps such as
Netflix, Skype, Google Voice, Sprint Visual voicemail)
all working at least as well as on a Sense or stock ROM?
Thanks in Advance,

[Q] best kernel for performance for Cloudyflex 2.6

Hi,
Is the cloudy kernel the best for pure performance in terms of lag? Not looking for battery or other performance enhancements.
Is cloudy kernel 1.5 the latest ( just to make sure i have a backup kernel to re-install just on case)?
Is the tweak on hidden menu for HIGH TEMPERATURE still relevant with these kernels?
I am running with ondemand governor.
And just to make sure:
- to install a new kernel i just boot to recovery and flash the kernel without any wipes, right?
- i have xposed and some G2 tweaks running, i don't need to disable/reset or anything?
Thanks for your help! I am still learning.
Nico.

Hello Nico.
I'm hoping that I can assist you with this topic.
First off, regarding the kernel you have plenty of choices. There are two, however, that I'd recommend.
1. Dorimanx Kernel. That kernel is absolutely amazing with LOTS of tweaks, thermal protection, ad-blocker, allows overclocking to 2.8Ghz and much much more. I can't list all the features because they are so many. But there's one thing in particular - it's fast. Dorimanx has created a hybrid kernel from 3.4.xxx and 3.10.y source codes. This is my go-to kernel.
2. Bruce Kernel. It's a modified stock kernel with Bruce's own tweaks. It's fast, very battery friendly but lacks customisation. It also doesn't have thermal protection or any thermal throttling.
Now to your other questions:
Yes, Cloudy 1.5 should be the latest.
I wouldn't mess with the ROM thermal protection found in hidden menu. The gain in speed is most likely negligible but you make your phone more prone to heat damage.
Ondemand governor is great for smoothness, but you'll have a ton of options if you decide to use dorimanx. I use alucard because it's the sweet spot between amazing battery performance and smoothness.
You can install a new kernel without any wipes. Kernel doesn't interfere with ROM as such and you don't have to disable anything. A Kernel is basically what makes software and hardware work together.
I hope this helps!

Thanks a lot for your answers, these are exactly what I was looking for.
I just flashed Dorimanx, and without knowing too much on how to tweak it (more on that later), it is really smooth. I am keeping it!

OK, great to know, it is so often repeated online that I used to have it. It is now off, absolutely no noticeable difference!

Thanks. Flashed perfectly, twice (I had trickster mod on and wasn't sure what it reset at boot, so uninstalled it and re-installed Dorimanx.)
Got 1040/2900 on geekbench even if that is not really what I care about. I had 950/2750 before, not that much noticeable difference in %.

OK, we're onto kernel tweaks , I have a few questions:
I discovered that I had STweaks installed, so let's use that.
1) Apart from governor alucard, what other settings should I apply? You mention thermal controls. I expect the defaults of STweaks are OK? If not, what should I do?
2) I found a GPU governor, should I do something there to have better performance?
3) my real goal is to achieve super smoothness when interacting with the phone, I don't play high CPU 3D games or anything like that. I want the phone to react instantly when I press somewhere or open something or press home or recent apps. Any advice? I modified touch boost frequency...
4) if I "reset settings to default" in STweaks, will it reset to Dorimanx' installed default as I just installed the kernel?
5) so that I don't bother anyone anymore, is there a manual about all these tweaks in Dorimanx/STweaks?
Thanks again so much!
Hey bud, I dont know if u found out the answers to these questions but I can share my information with u as I see nobody answered it

Hey there. Thanks a lot for your answers, despite the thread being so old.
I actually learned a lot since i posted that
I use 2x intelliactive, 2x alucard, alicard HP, max freq 2.3, 2.3, 1.9, 1.9, gpu 100-533, i/0 read 1024, dirty tatios 5%/10%
Your settings look interesting, you sure you get great battery life? With 2 cores min? I am going to try
No mate, I said that's settings for u, u said u don't care about battery, so I tried to give u the best settings I can come up with for performance, I myself use 3 cores max, all 2,3 ghz 1 core boost, Alucard on-demand Alucard. 1024. 100 320 GPU. It's pretty smooth with art. But if I wouldn't care about battery, I would do the settings I told u. Hehe

no worries!
I learned to care more about battery I realized that it is really smooth anyway. I have a lot of SOT daily (movies, etc) and realized that using performance settings just drains too quickly and is not needed.
I do put animations to x0.5 (transition animation to OFF).
What I am really struggling with is home redraws... A bit better now, but they used to be 1000x times a day.
I would run with ART but it takes a lot more memory, and with my 16 GB I don't have enough memory left when running ART.
Buddy, I am on 16 too. I had 8.5 hours sot with art and cloudy 2.1!! I use nova launcher and I am happier with it can give it a try

I have a few very large apps (navigon, games,...) they take 2-3 GB.
I al so have movies, remaining is only 1.3 GB.
If i want to backup ROM i need to delete obb files, etc. With ART i will have nothing left!
Tried niva but didn't like it. Will try apex again maybe, but i really like the look of G3 home.
Hmm, I see. I didnt know that internal memory and has a thing to do ART, I just made it ART and everything was ok. Launcher is a matter of taste I guess. For lg launcher, I read that there are some hidden settings to lock it in RAM, so that it doesnt redraw that often, maybe u can take a look for that. Hope to share more information for better experience with our phones
@bloof I forgot to tell, I also like how g3 theme looks, and I use a g3 theme with my nova launcher. If pm me ur gmail, can send u my screenshots

What's Your Reason for Not Using the Stock Kernel...

I see a lot of people are quick to flash AK, Franco, Tyr, etc before they even give the kernel that comes with the ROM a try.
From my personal experience, the kernel that comes with a ROM is always faster & snappier than aftermarket kernels (no overclocking).
Also, correct me if I'm wrong, but the kernel that comes with the ROM is optimized to perform best with the ROM. Optimization is the main reason why Android is one step behind of iPhones. I don't know about you guys, but I want my phone to be fully optimized which is why I stick with the stock kernel most of the time.
I guess I'm also one of these people who are quick to flash a aftermarket kernel.
But I think the aftermarket ones are the more optimized ones.
Anyway I never had problems with the stock kernels.
I love the extra work devs like Franco and AK do. Sometimes I get some reboots with Franco but overall its a good experience. I just have some Franco loyalty from when I used his kernel on nexus 4 lol best kernel ive ever used. Not sure if I'd say the same about his one plus kernel but if there's any issues I'd blame cm not him

I used to be the same way on my older android devices.
It seems like now flashing a kernel is no longer need to improve performance (sorta)
The hardware on the oneplus one is beast & android has come a long way in terms of software.
Because I love the sound control in AK Kernel

I do the exact same thing. I try and delete all of the unnecessary google play stuff as well as apps I don't use often. And use greenify as well.

I definitely have to try that out. I usually always skip pass it lol..
I use franco kernel because I get better battery with his kernel (compared to stock), and it's always up-to-date with most of the patches, while with stock you'll have to wait until the next OTA to get some patches.

Can you please name bloat stuff which still comes with Cyanogenmod what should be deleted? Would be helpful for me to get my phone as clean as possible/neccessary.

So, there is no stuff which still comes with systems like cyanogenmod which i can delete without getting any trouble? If yes, how do i know which stuff this can be?
Purchased Franco Kernel Updater and if I didn't use a custom kernel (or Franco Kernel) then I spent money on something I'm no longer using.
Also because I'm not a fan of mpdecision.

Same here switching between AK and Franco.
Both are a good choice.
But as mentioned before, the hardware of our phone is :good: so no need to flash a aftermarket kernel to gain more performance.

Why not? Intelliplug?

Anything other than mpdecision, I personally prefer Franco's hotplug algorithm which is his own implementation of powering on/off cores.
Mpdecision is Qualcomm's implementation of powering on/off cores.
I personally am not a fan of Intelliplug,
3 - Don't even bring intelliplug on this. With all due respect to faux, that driver is a butchered solution to control the cores. The code is a mess and, in my opinion, just doesn't make any sense. I've worked on my Hotplug driver for years and it works as simple as need be, with appropriate userspace tunables for users to tinker with.

http://www.reddit.com/r/nexus4/related/158t1i/custom_kernels_a_guide_on_what_you_need_to_know/ has a great reading on mpdecision and why it is not good in their opinion.
--mpdecision--
All Qualcomm based phones have Qualcomm prorprietary userspace binary called "mpdecision" aka m(ake)p(oor)decision. Instead of letting the kernel itself to decide what frequencies and how many cores to run, this "mpdecsion" binary polls the kernel run queue statistics and decides for the whole system the "optimal" frequency and the "optimal" number of cores to use. The concept is fine, except the decision making is done in userspace and it's 100% closed source so there's no way to tweak it and there's a latency (because all userspace binaries needs to "poll" the kernel for the latest information which is slightly delayed). - faux123
ELI5: mpdecision is a proprietary Qualcomm daemon that makes calls to the SoC (the entire chip your phone uses) to manage the cores. The OS (PowerHAL) makes a request to mpdecision and then mpdecision makes a request to the first two cores to ramp them up. - _motley

I like to mess with my phone. Simply because I need a kernel fully optimised kernel for the device. Not to say that the developers aren't doing a good job, but in my case, a user sometimes knows better than the creator themselves.
Unless the custom kernels do not satisfy me, I'll revert back to stock.

This phone is fairly clean out of the box. About the only stuff worth freezing or deleting would be some of the google play apps if you don't use them. For example Google play books, news stand, or games.

Best kernel for stock lollipop

Hi guys,
Would love to know your opinion about the best custom kernel to go along with stock Android.
Please share your experience.
Stuxnet is good for me
I have been using franco's since I received my N4 and haven't really been attracted to anything else.

Ive heard it has some issues qith the latest r214 build. Would love to try but looking for it to be a bit more stable
if you are a one time flasher (ie you like to flash and not tweak the kernel or anything) - Franco, Mirage are suitable for you.
if you like to tweak the kernel, you can use - hellscore, Hellsdoctor or ak - its not that these kernels' defaults are not good, its just that they can be more optimised with profiles with synapse - for eg ones from gorilla_p (bit.ly/makostuff).
if you like kernel tweaking with dedicated apps - faux or Semaphore kernels.
i am not able to give you a more comprehensible reply because you haven't specified what feature you are looking for - more SOT or better performance.
more SOT - HD or ak
better performance - Franco

Thanks @Theodeus
I've heard a lot about hellscore and hellsdoctor.
I'm looking for a good balance between performance and battery life.
Ive heard that franco gives a good standby time as it only uses 1 ir 2 cores in stand by.
Do hellsdoctor also offer the same. Im using tricksterMOD now and don't mind a bit of tweaking as well

one question... how to REALLY TEST and compare a kernel?
sometimes adding and modding the phone with custom rom, kernel, greenify and other manual modded cpu governor etc...... it's almost IMPOSSIBLE to understand if the perfornance, or battery life is affected by a kernel or something else.
A person could obtain a bad battery life but the culprit could be ANYTHING.....
so IMHO the easiest way to compare a kernel is the numbers of features and OPTIONS that allows it.... something like how many governor, i/o schedulers , tcp algorithms, dt2w..... and so on... because a PERFECT kernel... could be perfect in some roms.... and worse on others.....
there are too many complications about the number of apps, which apps, to use greenify or naptime/forcedoze , and a possible incompatibility with a specific ROM with specific kernel.
after all........ maybe the simpler test is to keep the same configuration of the rom for at least 1 week, make a nandroid twrp backup, flash 1 kernel, keep it 1 week ( and see results), then restore twrp with stock kernel/rom , then flash the second one kernel, keep 1 week, then restore backup, test 3rd kernel.... and so on? making it sure NOTHING CHANGE, no greenify change... no gaggressive doze setting change....
it would be nice if other people would write here they combination of precise KERNEL + ROM used to achieve a great battery life and SOT.......
No doubt all these kernels are well tuned and devs are making them better & better every day. I always use RADON KERNEL and it works with every rom just perfect, never tried AGNI though, two days back I flashed ElementX and Franco kernel but I noticed two big cores are either going "offline" or shutting them off permanently. @franciscofranco replied those two cores were thermal throttled or something (may be....) but after RADON I didn't noticed that issue, all 6cores are back online . So for now I'm sticking with radon I'll flash FrancoKernel next week and see if thingd sorted out..
Most off all I think we kenzo users are blessed to have all these big names in development thread.
Why isnĀ“t Lineage Os on the List (a.k.a Cyanogen Mod)
I certainly like Radon best . Save battery and not lose performance .
I don't like AGNi . Because it update too frequently sometimes and little waste battery .And that ,I don't like the AGNi Controller ,One reason :For users who use other languages, this apk is difficult to translate . But , I can't deny it is a good kernel .
About Other kernel , I did not use them for a long time . So I do not understand.

Battery and performance are undeniably affected by your kernel.
For example, the battery life on Nitrogen OS kernel is amazing, and the reason for that is, reduced performance. It's not slow, it's smooth really, but it's slower than Radon's balanced configuration.
And I think your argument that a kernel can be judged by the number of features, governors and schedulers it includes is wrong, because you don't need multiple governors or schedulers to get a good experience.
At one time, you'll only be using one, and that's why the stock configuration of the kernel matters.
I think every custom kernel has their advantages and disadvantages.
All we need to do is tuning it.
For example, I use Franco kernel and I changed the input boost ms for better responsive.
Or I use nitrogen kernel and tuning the governor for better performance.
However, I choose latest ex kernel manager app to tuning the kernel. It's more friendly ui and more reliable.
And the best thing is latest version of radon/franco/exkernel/nitrogen/agni has unified fp support.
