Dear fellow xda members,
I have a question that I could not find answer for via search, so I would like to ask you to help me.
This is a great ROM, but I wanted to get maximum of battery life so I installed SetCPU. I chose several different profiles and CPU governors, but I ended up with a significant lag and even worse battery life. I am using stock Kernel. My questions are:
1. What SetCPU settings should I chose for my Note 2 in order to have best battery life with minimal impact on performance? (ondemand, pegasus,...?)
2. Which KERNELS beside stock and Devil are compatible with awesome Dr Ketan's v6.1 ROM, and which Kernel do you recommend for best battery life? Also, how do you set parameters for those kernels also?
Thanx in advance, dear colleagues!
This one could be compatible with this rom http://forum.xda-developers.com/showthread.php?t=2311094
For further answers, scripts and settings there are several posts.
Edit: Yes it works:
I am testing these settings now:
gove- yanks zz move
schedulers row,row
cpu freq- 1600 mhz
cpu undervolt -20
gpu default
gpu uv -20
threshold- more batt save
sd read ahead 1024 1024
power saving load bal- max savings
zram 500mb

Hello!
I think that this kind of thead would be nice for noobies like me. I know that there are already good rom, kernel, mod and tweak lists but sometimes it can be very difficult to find combo which is perfect for you. This is not a thead for comparing roms, kernels etc. It would be nice if as many as possible posted here how your little SGY had been customized and specially for what kind of use.
Post atleast ROM and KERNEL and USE like this:
My SGY
ROM: Hyperion 8 GM Final
KERNEL: Savie #73 (Governor: OnDemand, I/O scheduler: sio)
TWEAKS: V6 SuperCharger and KAK
USE: I use SGY daily as my current phone so it has to be stable and every basic features must be working. I also wanted as much as possible performance without battery draining. Now my SGY run over 2 days for basic use and one day for heavy use (internet and little gaming). I also wanted bassboost for my audio player. I think that my performance is very good now and I can even play GTA III with only little bit lag (using Chainfire 3d) but the most reason for this combo is stable and fast normal use (no apps forsing down and freezing)
Sorry for my bad english. If someone want to write this with better english, go ahead.
Any one else didn't want join?
There seems to be awesome traffic in this thead!
Well, I'm going to update my combo anyway:
ROM: Hyperion 9 GM Final
KERNEL: Merruk 2.5 #206 (Freqs: 1248Mhz/312Mhz, Governor: SmartassV2, I/O scheduler: Noop)
TWEAKS: None
USE: Now my little SGY is my second phone and I don't use it very much anymore. When I go to gym I use SGY as mp3 player because my other phone is too big (5''). I also browse internet sometimes. With Hyperion 9 and Merruk 2.5 kernel SGY is amazingly fast and internet browsing is very smooth. Only disadvantage is that battery drops pretty fast. Long live SGY!
yeah... for what?

Then everyone can find a good combo for their SGY. Some tweaks and kernels aren't compatible with some roms etc.
Here is mine...
ROM: CyanogenMod 7.2 - BroadcomCM [TOTORO] [RC 4 - 09/03/2014]
KERNEL: CM Specific Basic Kernel - BroadcomCM[TOTORO][v4.0 - 07/3/2014] (Freqs: 832Mhz/312Mhz, Governor: Performance, I/O scheduler: Noop)
TWEAKS: None
USE: My little SGY is my first purchased phone and I use it as mp3 player & for GMAIL. I also play games. My SGY is amazingly fast.
:good: Long live SGY :good:
** Note: This kernel is end-of-life and will no more be maintained. There will be no LineageOS 15.1 or newer kernel be available anymore **
Hi all,
some of you know me from the Samsung devices area, where I provide my kernels already for more than two years to Galaxy S3 and Note 10.1 users for all sort of platforms (Samsung, Cyanogenmod, Omnirom etc.)
Please note:
I am not heading to have as many features as possible implemented, this is not my design goal. If you are more into that, move on to other, good existing kernels. If you are searching for a good mix of improvements and new functions while not sacrificing stability, you are welcome here (see below the history section for more info).
Compatibility
Important: This kernel is only meant to be compatible with official Cyanogenmod / CyanogenOS and nothing else.
So when the kernel does not run on custom rom XYZ, do not even bother me with it or ask hundred times in the thread for compatibility.
I could not care less about it !!
Important notes
1) When using new anykernel concept Boeffla-Kernel: Flash stock kernel of rom first !
2) Do NOT use TWRP's function to root your device after a clean rom flash!!! The installed supersu version is not up to date and may cause a bootloop with latest COS/CMs kernels !!!
3) Make sure you flash the correct kernel version, depending on whether you use cm11s stock or genuine cm11, COS13.0, COS12.1, COS12.1.1 or genuine CM13 !!!
Also note: You have to use Boeffla-Config app which I provide on my homepage to tweak the kernel. 3rd party apps will not be able to unleash the full power of the kernel.
Saying that, the Boeffla-Sound app in Play Store is not designed to work on the OPO, neither was it developed by me, hence it will never work on the OPO ever. Boeffla-Config is the way to go here !!!
Support
First read the FAQ section on the Homepage !!!
Click here to learn about all possible kernel settings in the config app.
Click here to learn about using the config app.
I will refuse to give support if you do any undervolting and experience freezes or hot reboots.
I will also not provide any support if you do not use Boeffla-Config app to tweak the kernel, other 3rd party tweaking apps are known (and intended) to cause issues.
I will refuse to give support if you have xposed framework installed and reporting any kind of weird issues. My opinion to xposed it quite clear: too powerful for >90% of the users that just mess up their system with it.
Otherwise, you can get in touch with me via the support e-mail address: [email protected]
Please provide kernel version, rom version, a detailed issue description and ideally supporting screenshots or log files.

Google gcc 4.8 toolchain used for best stability
Always using latest Initramfs
Always based on latest OnePlus One kernel sources
Note: I do NOT upstream the kernel to higher Linux kernel versions anymore as this usually has zero benefit but likely introduces new issues + is a waste of effort in the end

History and design targets
Basically I created my first Boeffla-Kernel in 2012 as there was no kernel for the Samsung Galaxy S3 around that had exactly the mix of functionalities that I wanted. I wanted to have full flexibility in undervolting and charge rates for instance, but did not like the sharpness and/or brightness tweaks many kernels have implemented as per default.
Hence, I began to create my own kernel after a while, adding all the features I like. This is the result of my work, which in the end I decided to share with you. I hope you like it as much as I do.
The objective of this kernel is to have a kernel for daily use. It does not aim for best battery life, or best smoothness or best benchmark scores. Also it does not aim to have the broadest feature set available everywhere.
It aims more for a good mix of all, not sacrificing stability and functionality in the end.
And - most important: It aims to stay quite close to stock !!!
These design targets are also valid for the OnePlus kernel here!!!
This said, I will definitely NEVER implement:
things I do personally not need
things I do not like
things that are in any way dangerous
anything which is highly experimental
custom hotplugging algorithms
a CAF based kernel
anything that requires upstreaming of kernel parts to a higher kernel major version
So do not even ask for it if it falls into the listed categories. Everything else I am happy to check and decide.
And: I do not really care about benchmark numbers, they say almost nothing as long as something is not completely wrong. Important for me is the feel-good factor.
I am also not interested in gaming at all, so never expect a gamer kernel. It will just not happen...
Compatibility
To reiterate it again: Flash the correct kernel depending on whether you are on stock cm11s or genuine cm11 !!!
Configuration of the kernel
To tweak and configure the kernel, manually load and install the app "Boeffla-Config V2" from the downloads section on www.boeffla.de.
You need at least version 2.1.48 or higher for the OnePlus One Boeffla Kernels.
Donation
If you like my work, feel free to donate: Donation-Link
If you donate at least 2,49 EUR (to be in line with the donation app prices on Google Play store), you will receive a personal donation code which unlocks some nice little comfort functions in Boeffla-Config V2 on top.
Source code
All sources can be found in my Github repository: http://github.com/andip71
Credits to developers
Of course, I had never been able to create all that by my own. So I want to give credits to the really good developers around, that have given me all the inspiration and from which I cherry picked lots of the implemented functionalities:
* ZaneZam
* Yank555
* Hardcore
* Chainfire
* AndreiLux
* Netarchy
* Gokhanmoral
* Simone201
* Mialwe
* Entropy512
* Faux
* Harunjo
* FranciscoFranco
* Ak
... I just hope I did not forget someone. If so, please let me know and I will add you of course.
Thanks to all of you for your great work !!!
Disclaimer
*** As always - Flash on our own risk! ***
Make sure you flash the correct version depending on your firmware version!
I can and will not take any responsibility for bricked phones or lost data.
It is generally recommended to run a complete Nandroid backup in your custom recovery and safely store your personal data before you flash a new kernel.
Cheers and enjoy

Hi,
oh yes, zzmoove is already in
Thanks to master @ZaneZam, who was working together with me in the past 2 weeks on that topic.
If you loved my kernel already on the S3, you will even love you have the same kind of "structure" around the kernel. Same config app, same comfort functions there etc etc.
So, ... enjoy
Andi
waaaaaa... my lord.... welcome .... missed u from S3....... so happy...
are we expecting eargasm again ???
Lol, how nice... many "old S3 chaps" here. Good to see you again guys

Not in my plans as I have only one device. So the same goes as long time ago for the S3 and n8000.
One device = only the "official" firmware. This is still my golden rule of thumb
If enough people help me to get a second device, it would change of course.

I know.
But I loose features, and like for a daily driver phone to stay on the official firmware the vendor provides. That is my concept for more than 3 years now and I was always good with it.
So, no intention to change.
The question from other side is (although it is OT): What does CM provide me which CM11s does not have?
I am not missing anything, thats my point
It is not about invites, but paying another 300 bucks is not possible for me this year anymore (spent around 15 k€ for relocations, my car got stolen in February and so on... was an expensive year for me).

Sometimes life is a b**tch
But all good now. Just not the money left for another OPO at the moment.
Especially as I still am not sure whether I should also get a Galaxy S5 on day.

No, of course not.
This is technically impossible. There are things in Samsung that do not exist on this hardware (e.g. big parts of boeffla-sound).
And vice versa.
And some are not needed as they are included here by default (e.g. touch wake etc).
If you look carefully at the feature list, you can spot the differences
Andi
Pretty sure you can get the kernel to work with AnyKernel, but of course, when you do this, YMMV. Since it's designed to work best with CM11s, it might perform worse on other ROMs (and then there comes the complaints, bugs, issues, etc.). Besides, I don't see any need for any other ROMs than CM11s. It gives you everything you need.
ive used that kernel until last week on my s3, it was by far the best.
(boeffla sound was great)
hoping for a cm11 version sooner or later for the 1+1 :victory:
I have used your kernel on my s3 for along time, it's awesome! Very happy to see your work on OPO.
Just ask one question, I'm using f2fs with ak kernel on my OPO now, so does this kernel support f2fs filesystem? Cuz i didn't find it on your feature list..
sorry for my english
Hello, which rom and kernel are recommendable for that time ? I want battery friendly and don't overheating so much.
Thanks,

Latest aosip rom with nebula v10 is the best I can do when it comes to battery and performance, you'll need kernel auditor or ex kernel manager to get 100% the best battery possible my friend.

@Dlind could you help with the setup that you've found working the best? So you are running latest AOSiP ROM and Nebula EAS kernel, so how's Nebula compared to the one which is included with the ROM? What kind of tweaks you've applied with kernel configuration apps? Anything else?

I like the kernel in the regular aosip. But what nebula has over the aosip regular kernel is, the cpu governors. I've ALWAYS, ALWAYS, ALWAYS! had issues with sched/schedutil. They lag with youtube. And are biased toward power to much for my liking, but if you don't watch youtube much that's ok. But sched/schedutil also has given me the best results when multi tasking. I personally love cultivation. Its a smarter version of good old interactive. There's also options for using a slight over clock to cpu and gpu. Also with this kernel there is an adjustable throttle for when the cpu overheats it in Celsius btw. All these settings are in ex kernel manager and in kernel auditor, they both are great apps. Under cpu mic spot in the bottom turn off perfd and leave wq_power_saving on.
