Which Kernel

Opinions on which Kernel I should install for all around best performance. I am not running any rom right now just stock 2.2........ Anything that will help me decide which one to install.
Thanks

Try them and see which works best for you. If you don't need the overclock speed, then stick with one that's stock or underclocked but undervolted also. This will save you some battery power. I think it's hard to say what works for me will work for you. One of the effects of having choices.

[Q] Recommended Kernels?

Hey, I've got a question, what is the most recommend kernels for cm10.2 or AOSP 4.3? I'm so confused and torn because there are so many!
I need a kernel for great battery life but still awesome improved performance in games, video streaming,etc. Please Help!!!

There are only two forms of kernel.. JWR and JSS. most recommended would be Faux,franco Hellscore.. See the ROM you are trying and accordingly flash the kernel.

this is not the truth, this is only your opinion, nothing more.
every device reacts differently with every kernel. therefore it is best to try as many kernels as you can to find the kernel that is best with your personal device. one person say that xxx kernel is the best, another says that yyyy is the best, but in reality there is no best kernel. anyways, these what are the best kernel/rom threads are not allowed on xda, as "best" is an opinion not a fact.

There is no "best" ROM/Kernel threads allowed on XDA, reason being is whats "best" for you may not be "best" for someone else . Head over to the development section and see which "best" suits you.

[Q] Custom Kernel

Hello,
I use SM-N9005 4.4.2, Baseband ver. N9005XXUENC2, Kernel ver. 3.4.0-1168347, Build number KOT49H.N9005XXUEND5.
It's a rooted, stock ROM somewhat modded with Xposed, Android Tuner app etc.
I'd like to flash a custom Kernel which will allow overclocking, eXtended battery life and some other neat features I hope more experienced XDA community will recomend.
So, what Kernel would you recomend as a mix of stability and performance for my stock TW rom? I am fairly inexperienced in these waters. Are Baseband version, Build number etc important when deciding on a Kernel?
Any advice would be welcome. Thank you in advance.

Try n3 by wootever, sneakykat and leankernel (last doesn't have so many features but is great for battery & performance) and my personal favorite ael kernel of course.
The kernels are pretty easy to flash just put on SD flash and wipe Cache & dalvik. So don't worry if you don't like the kernel just flash another one.
One more thing don't put two different apps for kernel settings (like Synapse & Trickster) on the device cause that may cause conflicts. Have fun testing

Is it really necessary to wipe cache & dalvik? I've read in several posts that it is not required as there will not be any benefit.

To quote Hacre, an excellent dev on other Samsung devices - wiping cache and dalvik for kernel flashing is like filling your car tires when the gearbox is ruined...

Thanks for your response. I've flashed the AEL kernel, recommended by you.
What are the immediate advantages I received compared to the default one? How do I get the most out of it now - what next?
Thanks for your patience.

That is pretty hard to answer cause I do not know what settings you prefer. (Performance, battery or a mix of both). Download Trickster from app store or set cpu (for last you have to pay though). At first I would try to set just governor and I/O scheduler. In the link you will find some information. Got helped not too long ago

No for Benchmark maybe but most of the time the phone will crash then.
Personally I take 22565600 as max and 300 min with intellidemand governor and deadline scheduler but every phone works different that's also why you won't find any "perfect" kernel or governor.

how can I flash the kernel I tried CWM to flash the zip file but it doesn't work please help me to find my solution

smooth and fast in nexus 6p

Wich ROM, mod, kernel or combination of two of them give me the best experience in android?? I m looking for an Android system fast, smooth and best battery life. Thanks to all

If something was the best, nothing else would be used as there's no point in using something that's inferior when you can get something better.
There is no best, I suggest you read each thread and pick one that suits your needs. Saying X ROM and kernel is the best is like saying a specific vehicle is the best...One may say a Ferrari and another may say an F-350. But who's right?
Some people like roms and kernels bloated with 1000 customization options filled with placebo "optimization and enhancements". Others prefer a clean, minimal ROM without all the useless bling that they'll never use.
P.S. there's probably 10 threads like these, and possibly 11 by next week that you could've read through. I'll just copy and paste this same post on the next one.

Currently using PureNexus nougat with ElementalX kernel. The experience is pretty good.
Using the phone for SMS/MMS, YouTube and web browsing. I can get ~ 5/6h sot with a full charge on WiFi and ~ 3h30 sot on 3g/LTE which is enough for me.
Also using custom CPU governor profile in EXKernel Manager helped me with battery life without affecting performance (at least not that I noticed). You can find more infos here:

I am using the stock ROM with the ElementalX Kernel. Very happy with the performance of the phone. I arrive at the end of the day with 40% battery on average

F2FS + Dark ROM + FLASH kernel ! That's the best combination and I am a serial flasher

These people that are saying there isn't a best ROM, I don't really understand the reasoning behind this. There most certainly is a best ROM kernel combination. Otherwise all these ROMs and kernels would be exactly the same right? Sorry to say, some are better than others. This is just a fact.
If you want speed, smoothness, glass, breakneck speeds, great battery life, there really is one only choice.
Uber rom by Chad and faster kernel by Chad.
Why?
On f2fs, (trust me, you want f2fs) I have yet to find kernel or ROM combination that beats this.
Its the only rom that's built with GCC 6.3.1, and the only rom built with clang 3.9.1. Coupled with f2fs, this rom FLIES.
I have flashed every single ROM on this forum and then some, and I'm telling you this is the best combination you can possibly hope for:

Uber rom by Chad I definitely agree is the best. I tried using his faster angler but it caused problems with mods like viper4arise so I am sticking with flash kernel. Uber by Chad is definitely the best rom though and I have tried so many roms like pure nexus, resurrection remix, dirty unicorns, sixRom, lineage, cyanogenmod, nitrogen, Cortex and so many more.

Is the stock camera working on either Uber or Dark ROM with f2fs file system?
Thanks

There's no such thing as a best rom fact, but only best rom opinions, which isn't a good idea to ever discuss here. [emoji14]
As for battery, that all depends on you as a user to manager your battery life your way. I get 4+ SOT easily and I listen to a lot of music and text a lot.
As for what I'm using, I'm running ABC Rom with franco.kernel, root, and V4A. ?

And other thing, you say me I have to flash to f2fs first before install this ROM and kernel?? Or I don't have to flash previous?

I basically just wiped cache and dalvik/art cache and flashed the rom and kernel and all my mods. I also made sure to do stuff like rename audio effects and everything I did to make it work with flash. I use stable 2.4 deutronomy aroma installer. I was talking to someone else on this rom and kernel and he said he had the same problem too so it might be hit and miss or maybe you flashed it different than us. Please tell.me what you did to get it to work. Thanks

What partitions do you guys convert to f2s besides cache? Data as well? Everything else remains ext4?

Running stock has been great for me lately. Downgraded to 6.0.1 running Xposed for pixel mods. Amplify and greenify. With exkernel has been a great experience so far. Near 7h SOT yesterday. Will be going back to 7.1.1 soon, as the February update is out.. I heard lineage OS has good battery life. Will be trying that out soon in a few days.
Read the threads on XDA and good luck!!:good:

[Discussion] Favourite Kernel and Why ?

We have another post for ROM. Why do we not have another post for Kernel ?
As we can see, we have more than 5 kernels that are from XDA developer or someone else. But which one is really good for your ROM and which one still keep updating ?
I have been using OP5T for 2 months. Have used so many kernels but i still got stuck in those and do not know which is more stable. I am planning to use the kernel from Blu_Spark. Is that good ?
Post your favourite kernel and tell everybody why you use that. It will help newbie to pick what they want.

I am using Flash kernel at the moment but I have already tried Blu, franko, arter, ElementalX etc, but honestly for me it's difficult to see any difference since this phone have already a great battery life and great speed. On my previous phone (S8) the custom kernel gives a big advantage since the phone have tons of bloat and and isn't running stock like Android.

I have tried Blu and Franco for now and both have been very good. I really think kernel performance depends on the combo with the ROM as well as your device. I'm on Liquid Remix with Franco currently but I may give Resurrection Remix a try with Flash. If I had more time, I'd flash every ROM with every kernel to get a feel for all the possibilities LOL. :good:

For me Franco and flash kernel are the Best.... Now with ob3 with Franco kernel
Enviado desde mi ONEPLUS A5010 mediante Tapatalk

Did the Franco improve battery or performance? Someone Tried the Boeffla?

At the moment, both Flash Kernel and RenderKernel are great options in my opinion. I have tried most of the other kernels on xda and if you are looking specifically for smoothness/speed, these are the two you should test first. I do not run battery cycles; everyones daily use scenario really differs too much.
Flash Kernel currently has some kernel features I need (Kcal support & wakelock blocker) while RenderKernel does not have these features quite yet. While it lacks in some features, RenderKernel is undoubtedly the smoothest kernel for 5T right now.
I am on a 5T with OOS 5.0.3.

I like Franco but recently some custom ROMs have WIFI cannot turn on problem after I flash Franco kernel.
:fingers-crossed:
(Don't blame any devs here just sharing.)

I haven't really played around with Kernel choices much.
I use and appreciate the professionalism of ElementalX kernel.
With it's options to adjust for extreme brightness, it quickly became a favorite a couple years ago and I've just stuck with it since.
Now most devs are adding high brightness to their kernels.
I guess I can start checking other kernels out.
I do like that ElementalX stays very stockish, reliable.
I can pretty much flash it and feel confident nothing weird will pop up over the next few days.

ElementalX, Franco, and flash were all my go-to kernels back in the 6p days (just a few months ago, lol), so it's hard to pick, especially since they all ended up on the 5t. Right now I'm on exkernel though I am partial to flash. Battery life is amazing on all 3, but the overclock on ex just adds that extra bit of smoothness that I've never experienced before. Call it placebo but I just love this kernel (exkernel).

any more input?
im curious to know if fsync affects battery performance at all, can someone also test this out if you are on a kernel that enables disabling the fsync feature

Tried it but didn't notice any difference.
Technically it should improve performance when using the phone, but it won't be noticeable.

Custom kernel has nothing to do with google play services. You need custom recovery to flash a kernel, but most kernels for op5t are "flash & forget" which mean there is no reason to change the setting of the kernel.

maybe not Google play services specifically, but with my latest phone (zuk z2), kernel was directly related to deep sleep
stock OOS/kernel has a serious issue with Google PS in terms of deep sleep. Besides that, I dont feel any need to flash a custom kernel. SOT is incredible already, and performance is really fluid.

If you are OK then there is no need to flash a kernel. If an app is crap (like Google services or facebook) the kernel can't do miracles and its not kernels job to control wakelocks of user apps
