I'm really very happy with my Nexus S 4G. It's unlocked and rooted, but otherwise pure stock and I really like it that way.
Coming from the Hero it's a pleasure to have a phone that doesn't require heavy modification to make it perform properly. Still, I miss the thrill of flashing ROM's and kernels.
I would like to try a kernel...mainly to simply o/c a bit, but I don't want it to suffer stable and reliable operation. I recall with the Hero, some of the kernels would adversely affect things like the GPS, making it something I couldn't rely on.
So my question: what kernel can I use that is uncapped, but will otherwise be as close to stock as possible?
Thanks for your thoughts!
Kernels are pretty different over here. I don't even know what's closest to stock. They pretty much all have mods in them. Matr1x kernel is pretty popular. You may have to up the voltage for it if you oc to 14xx. 1200 seemed pretty stable to me with default voltages. Currently franco kernel is pretty popular. You can't oc it, but it seems pretty snappy without oc. GLaDOS is also being used a bit but i've read some mixed reviews and for me at least it did seem a little lagging at times for the short period I ran it. I tried Trinity kernel when I first moved over from the hero and it seemed kind of flaky though it's possible that could have been due to the kang I was running. There are a few others out there. Cm7 kernel has a lot of the same mods cooked in though it's likely not the latest updates. You will see a lot of mention of BLN and Voodoo. There are apps on the market for those features and there's an app nstools that has some kernel config settings you can adjust depending on kernel. Mainly just try to read a lot. Most of the roms and kernels haven't given me any major issues beyond the random reboot, which coming from the hero, just means "normal" lol.

Once you flash you can't stop O_O that my experience i'll direct you to Peteralfonso's kernel on his website here
Searching the forums would help you more than anything. You will get more info by searching, rather waiting people to reply here. These questions are asked on daily basis. And get the same replies everyday. I don't sound to be mean but seriously there is more info than you can get by starting another thread, only thing is you need to dig the info.
I have tried a few different roms and kernels and for once cm7 runs perfect for me w the supplied kernel. No reboots. Has been stable at 1440 performance for testing but I usually leave it at 1000 on demand.
Yeah they all have this blinking light crap in it now by default which I hate, and the lights turn off and I don't like that either. I want the light on when I'm using the phone and off when I'm not, not the other way around!

I like the bln mod, but I do not like the one that turns off the backlights when using the phone. It's just easier to use the buttons imo and gives a quicker visual reference for everything. Otherwise I mostly am left wondering what is up with all the black space.

I hear you on that, and spent a lot of time reading comments and concerns and problems about the various kernels available. They all seem to pretty much be experimental, with various idiosyncratic problems and lots of bells and whistles such as aforementioned BLN, Voodoo, deep idle, etc.
I thought maybe I was missing something in my search for a kernel that would allow o/c, but not have the stability concerns of a the feature-rich, highly customizable kernels.
I think the Matr1x kernel will be your best option, u can OC it till 1400mhz, what I don't recommend to do, but at 1200/1300mhz its pretty stable.
It also got many options like BLN, BLX, Live OC, touch wake, etc.
But if you don't want them, why you just don't use 'em?
Like just flash the kernel and keep it like it is, and maybe do some overclocking.
wanna stable ? stock kernel
basically , there is no kernel more stable then stock ...

franciscofranco's kernel (link) works best for me. It's fast (no lags even without OC, I'm running at stock 1000 MHz), reliable (I've been using it for at least month and I haven't got any random reboots or application hangs) and battery efficient (thanks to deep idle and other tweaks).

Never found a more stable kernel than Pete's. However, I've been on Glados for the last week or so and am seeing excellent battery life with Deep Idle.

personally i think overclock is totally unnecessary , why ? 1 GHz is sufficient to handle all job you require to the phone...
Best thing to do would be compile your own stock kernel with oc.

True again. I love 1100mhz because it gives you a bit more speed with no lagg, and you batterylife is still awesome.

with deep idle OFF, the difference between the two is minimal, idle stats displayed deep idle has been 0
Downloaded and testing peter alfonso's kernel now. Its very minimalistic, no options like deep idle etc, and u can OC it up to 1400mhz. Running 400-1100mhz for a day now and the battery life is just awesome.

WildKernel
As some of you may know, I've been working on a custom kernel for ICS/JB and its about done (for a first release).
Also I was previously planning on a beta testing for a selected few, but I released I won't have enough time to be hosting testing sessions, so how about this. The kernel is know free to use for the public, but all I ask is that your report and compare. I'd like to see if there's improvement or loss between the A6 kernel and this (battery, performance, etc.). Also please report anything good and bad so that I know what to keep and what not to keep for a final release. This also helps me push out fixes faster when presented with lots of information.
Current kernel features include: (If feature begins with a * then check below for more information)
Universal kernel compatible with all AOSP (NOT SENSE) ICS & JB roms
rebased to CAF (custom) Linux 3.0.39 kernel
Optimized Built in Low-memory killer w/ Fugeswap (as seen in the v6 Supercharger)
Optimized ram usage/handling (Swap & Zram)
Increased Wi-fi connectivity range
*Low & High power Wi-fi scaling steps
*Badass Governor
Lazy Governor
Imported Snapdragon optimizations used by the Sensation (Thanks Romanbb)
Lagfree Governor
Fast charging for unknowns and when plugged in to computers
HIGHLY Tweaked for the perfect battery life and performance
Bluetooth code from CAF
V(R), simple, deadline, noop, and CFQ I/O schedulers
*Ondemand & Intelli(gent)demand Governor
Stable Undervolting of the CPU
increased SDcard readahead speed
Tweaked Flashlight
Added more clock steps to the GPU for compatibility with low power browsing and GPU OC @ 320 mhz
Please wipe cache and dalvik cache
I dont suggest using SetCPU as it may cause bugs such as reboots, use CM or AOKP's built in cpu speed feature
Download Universal flasher for ICS and JBhttp://www.mediafire.com/download.php?q9bhv68k8dvai13
(Flashable for S-ON coming tomorrow when I have time)
You may find my source hosted @ Github
More information:
Badass Governor: This governor has built in profiling (like used in SetCPU but not as battery & Ram consuming). This is also the default and highly recommended governor. This governor features a 3 phase system CPU profiling system. This will change your CPU speed based on usage. This saves a lot of power as your speed doesn't just keep at one clock no matter how much your using you phone. A similiar profiling system is also used for the GPU and such.
Ondemand and Intellidemand Governor: Intellidemand is based off the Ondemand governor but features a 2 phase CPU profiling system with some added tweaks. Ondemand also now has early suspend support for low power browsing to save battery.
Wi-fi Low and High power scaling steps: This is a feature that will determine whether to use High or low power voltages on the Wi-fi chip to save battery. eg: Wi-fi will be turned to low power when idle or screen off. Wifi will be turned to high power when actively in use or in progress of a download. Take note that high power wi-fi voltage isn't necessarily "High" power but more of just "Stock HTC" power.

Awesome. Hope this fixes the battery drain problem from the A6 kernel.
Sweet. Will test tonight.
Il test this but not until Saturday morning will I have solid feedback
I'm going to have to use both Ankers plus my stock battery for tomorrow as I have school, then a football game, then a roadtrip so I will definitely take shots and post back with great contrasts I'm sure

CRUD! I got to my PC, downloaded it and read its not in Boot.img format! IM S-ON D:
Sorry wild, can't get it booting. Been trying forever. I'll redownload again when I get home.
P.s: it boots, but it goes right into a reboot after I hit homescreen. I don't think I can use alogcat to pull one, so I'll have to wait till I get back to my computer. Perhaps a dmesg a well.
You also plan on making something for sense ROMs?
If not would you mind if I grab your patches and implement it to a more enhanced virtuous kernel?

well im on my computer. the error (though im no expert) seems to be here
if you need the full logcat let me know and i'll try grab it again. that's the error going on right when the homescreen gets laggy on boot, right before it reboots.
i don't know if this is important to you, but this is what i get in logcat right before reboot
I'm sure i followed directions. I hope I'm not doing something wrong.
Edit: yep. Definitely not an expert. So it stopped rebooting after I unchecked "set on boot" under performance. Will be reporting back.

No, I'm running cm 9.1.0. Under settings > performance > cpu settings or whatever it is, if you have set on boot checked, the phone runs funny. I unchecked it in a desperate attempt to figure out what's going on, and it's been pretty stable ever since.

Can't we just extract the zImage from the universal kernel flasher, rename it boot.img, and flash? I thought they were analogous...
Edit: I tried it. Didn't work. "Boot Magic check failed". Guess I was thinking of Samsung devices. Bummer, I really wanted to try this.
Ok after a 10 minute self lesson on kernel kitchen I managed to compile a boot.img. Booted right up but I had nofrills with an "apply on boot" setting which screwed me over. Severe lag. I managed to access that app in slow motion and deselect the apply on boot nonsense. Now we are in business
Don't forget to uncheck all governor apply on boot settings before flashing! Also, on first boot go to a view CPU frequency place on your phone so you can wait until the phone settles before rebooting/doing stuff. Takes a little longer than you would expect.
So far the performance seems good, I'll report back on battery life later.
Edit: 3 consecutive reboots during 3 consecutive calls. Switching back to 3.0.30 (A5) for now. Since I didn't flash this officially I'd take this experience with a grain of salt but it is similar to what ekoee is reporting so IDK.
Hi xmc! Not that I question the knowledge of the senior htc community developers here but this battery issue I am facing with ROMs like virtuous is already nagging me out.
Now compiled yours and shocked that it also has the battery bug.(The not going to 100% bug)
So I decided to really look up the battery driver carefully awhile ago and noticed something strange in it. I noticed this days ago and thought this was ok but thought I would stand up and ask today.
In
arch/arm/mach-msm/htc_battery_8x60.c
htc_batt_get_battery_info
Could you tell me why calculation of battery is like this?
htc_batt_update->batt_current = htc_batt_info.rep.batt_current - htc_batt_info.rep.batt_discharg_current;

instead of this?

Seems like the batt_discharg_current is making my battery report less than the real value so I'd like to know why is the calculation like that?
I'm sorry for asking but I think you're the only developer on doubleshot who is approachable enough for me to ask to.

I'll take a look once I get home. Lol and just to be clear, i'm not the only dev for the DS. We got Blue6IX, jeffakajeff, strapped365, tbalden, Riyal , kornyone, and nbetcher. (Dont kick my a$$ if I skipped your name )
Flashed this with a fresh install of your JB ROM. Phone is really laggy when waking from screen off for a few seconds but then its ok. I'll look more in to this but thats what I'm seeing so far.
Flashing over CM 9.1 now, will test it out and report back with results. Really hope this takes care of the battery drain issue in 9.1.

Team Fah-Q Presents...
Scorched Kernel for Blaze ICS v1.0.29
Built with the Linaro Toolchain v4.7, the purpose of this kernel is to fix bugs, add features, add performance, and hopefully save some battery where possible. However, battery life will most likely not be as good as stock, since the device is overclocked and DVFS (dynamic frequency and voltage scaling) is turned off. I have done my very best to squeeze every ounce of battery life out of this device.
It includes a brand new CPU Governor called Scorched, developed by me and based on the lagfree governor. It focuses on saving power and reducing the usage of the higher CPU frequencies unless necessary, while still keeping responsiveness and performance intact.
The kernel should work with any ROM that is derived from the stock Samsung ICS release IMM76D.LH5, however I recommend using it with the Tweaked ROM, as that is what I develop it against.
This is a kernel several months in the making. Hope you like it
It is STRONGLY advised to do a full nandroid backup in CWM before installing the kernel,
as the installer will overwrite kernel modules in /system/lib/modules. You've officially been warned

FAQ
FAQ
What is the Scorched CPU Governor?
The Scorched CPU governor is rather similar to the lagfree governor both in its source code and its purpose. The difference is that while lagfree seeks to give performance-on-demand by increasing immediately to the maximum CPU frequency, Scorched jumps immediately to a mid-point frequency and then gracefully increases or decreases the CPU frequency as required. This provides both performance-on-demand as well as extended battery life.
multi core support
is there anyway of changing it to were we have multi core support ( in regards to offlining 2nd 3rd etc cores ) to save battery by chance cause some other kernels ive tested have that capability if i knew how to do so myself ( im slowly learning with massive reprocussions lol ) but would that be possible at all
awesome finally some scorchness for the blaze

Many thanks for your hard work.
However I've been using this kernel for a couple of days now with tweaked 2.1, and deleted battery stats but my battery life is really poor.
I've left the system essentially in standby for several full charge cycles but I only get 10 hours with next to no use, if lucky.
With stock kernel and Blz3r v3 and with heavy usage I would easily get 14 hours.
I'm still going to keep on using it and characterizing it and hope it gets better.

In my own testing, I have found that it is often worse to turn off a core completely, than to aim for a lower clock speed on both active cores. My theory is that the increase of speed with multithreading speeds up processing over the single corr, thus staying at a higher frequency for less time.
Just a personal observation.
I'm New
I'm sorry if i sound like an idiot, but Does this work on the stock ICS rom? I'm rooted btw
and does it support undervolting?
Thank you, Very stable and responsive kernel. Only issue I've had after installing the kernel is that when I try to send an app from play.google.com to my phone it doesn't show up. I can still install from within the phone itself just not website to phone, not sure if it's related to this Kernel or not but started after flashed it.
Again I'm not 100% positive that it's related so will need to do some more testing...

That's about right for the benchmark. I'm considering going a slightly different route with the kernel that may reduce performance a bit but should up battery life significantly.
Sick 2 year old at home so I've had limited time to play, unfortunately.

Hope your 2 year old gets well soon. Yes sacrificing a bit of performance to up the battery is definitelyitly worth it. Also seems like your scorched will outilizelize 384 and above, not sure how much battery can be saved but basic call functions and such can perfectly work on 192Mhz

Sent from my SGH-T769 using xda premium
Just wondering in everybody else's experience which kernel they find to be the best as far as battery life and performance goes. I've only seen 3 kernels for 4.4.2 being leankernel dkp (I believe that's the name of it) and ktweaker. Also what settings you found to be the best for you (governors, undervolting settings, overclocking settings, Etc.) I do a lot of facebooking but that's about it. So I guess let the discussion begin? I'm running the latest update of cm11.
Kernel are fone depended. Wat works for some ppl might not work for othets. Try them all out let them run couple days then u can decide which is better for you.
BMS and KT747 also have 4.4 versions
Best is subjective. Here's my subjective approach, so caveat emptor, take what I say as personal belief and not a professional benchmark testing...
For AOSP-based roms, here's what my experience is:
Lean: Easiest and simplest of the kernels. Has limited governors, but the tweaked InteractiveX is pretty effective at doing what you need. It also has a crapton of S3 specific tweaks to improve battery life. You can overclock to 1.72 (I believe...) Downside? The min frequencies are 384k, which means other kernels can go into a deeper sleep. The TCP algorythms are limited too, so choose 'reno'.
DKP: I love this kernel, but several people report it doesn't work for them. This kernel has a ton of governors, with 'freelunch' and 'asswax' being the best. There are also a lot of TCP algorythms (choose 'yeah' for best performance). You can overclock to something ridiculous like 2.1... but I keep it at 1.62; there's also deep sleep frequencies down to 54k (yes... 54000), but I tend to stay at108k. The downside? Some people can't get this kernel to work on their device and it doesn't have some of the battery saving tweaks Lean does.
KT: This is kind of the 'go to' for many people, because it has a standalone app that flashes in the process and the dev is pretty active with the S3 version here. Many of the same features of the previous two, but different governors and nothing that's a device-specific tweak; the kernel is developed for multiple devices.
BMS: This, to me, is a similar kernel to KT and was my go-to for 4.3 roms. I haven't used it in a while, so I can't speak to if it offers more governors and customization.
My take and choice?
Lean and DKP offer the best battery and performance than the rest; they seem to give the same performance, so really you can use either and be happy. I find KT and BMS to be sluggish (even with tweaking) on 4.4 roms AND they don't seem to put the device into the sleep I want it to for battery savings.
BUT... If you're flashing Gummy, give the stock kernel a try! It's the only AOSP-based rom that doesn't use the Cyanogenmod kernel and you can actually get some good performance out of it. I flash DKP over Gummy, but I also flash Lean some times.

Best is subjective. Here's my subjective approach, so caveat emptor, take what I say as personal belief and not a professional benchmark testing...
For AOSP-based roms, here's what my experience is:
Lean: Easiest and simplest of the kernels. Has limited governors, but the tweaked InteractiveX is pretty effective at doing what you need. It also has a crapton of S3 specific tweaks to improve battery life. You can overclock to 1.72 (I believe...) Downside?

By far the most in depth reply I've ever gotten on anything on any forums. I'll definitely give dkp a try with your suggestions, and I'll give that Rom a try as well when I get home on Sunday thank very much the reply
Backup, flash and find out.

Anytime, man. I'm ADD when it comes to roms and kernels, so I'm constantly changing them, but I really like the DKP/Gummy combo. FYI, if you're going to flash Gummy, get the 1/15 build... it's the one I'm on and is the most stable as of late.
I also recommend using the TricksterMOD app from the Play Store. It allows you to modify every feature the kernel will allow and can set on reboot.
Let me know if you want to know what my settings are in Trickster... I have it pretty dialed-in to solid performance and battery life.
Oh and as flyest said... nandroid, THEN flash. You should probably wipe dalvik and cache too. You don't have to, but I've had some bootloops before when I didn't.

I've only had issues like that when trying to flash anything my girlfriend's phone. However as far as trickster goes I can't afford the donation version at the moment.
What about I/o scheduler?

Don't even bother with the donation version... you can do everything you need with the free one.
As for I/O... you'll hear various claims that one is better than the other, but I stick with ROW. For the memory our device has 'Read Over Write' is the best scheduler you'll get with these kernels. FIOS is really the best, if you can find it, but ROW is what I stick with.
This may help clarify... or confuse you more lol http://timos.me/tm/wiki/ioscheduler

In my opinion, I found that leankernel is the best for battery saving/performance without tweaking...

Here's only stuff I tweak.
SETTINGS:
TCP: 'yeah'
CPU FREQUENCY: min - 108000 / max - 1620000
GOVERNOR: freelunch
SPECIFIC:
Force Fast charge: YES.
Multicore Power Saving: 1
MPU Voltages: Press minus once for -25. Note that this may cause a 'wake lag' with the screen, so revert to 1150 @ the 1.512 frequency if you have issues.
I also tick the box for 'kernel settings' on reboot, so the app overrides other settings that are in effect @ boot.

How do I change the tcp
In Trickster, TCP is at the very top of the 'Settings' window and should be a drop down menu.

Thank you very much
I've always used Lean Kernel for touchwiz and aosp roms. Very battery friendly and over clockable. I also like DKP for touchwiz. DKP has TricksterMod support and I believe Lean Kernel does as well. But if the rom has performance in the settings menu of the rom I use that instead.
Thanks to beepea206... I'm now getting 20+ hours of battery life off of one charge... I'm not changing a thing
To all moto x play users around the world!! I would like to say hello first!
The next is that how to get more battery life and performance
First of all, your phone must be rooted(which says unlocked bootloader), the next is a custom rom, I recommend using squid2's Cm13 and his kernel too
Download kernel auditor from play store, then go to cpu in that, then change the governor to lionfish, after that go to gpu then the governor to simple_ondemand, after that, go to I/O scheduler and change the internal storage scheduler to bfq and restart make sure you have turned on the apply in boot option for all those three
Conclusion :
CPU GOVERNOR:lionfish
GPU GOVERNOR:simple_ondemand
I/O SCHEDULER :bfq
Finally thank you all for having a look at my thread
Below are the screenshots, you can have a look at them
And I welcome all kinds of critics and reviews from you people
What is outcome after doing that? Can you give any comparison on it so that people can easily see what changed for better performance. Thabks.

Thanks for your curiosity in my post! And I would like people to implement the things I have said above in the post, and I request them to give me the poll answers and actually after they do what I have said they won't regret doing that! And actually I am using them and I am experiencing the thrill of using that
Hey hey!
I appreciate you posting this thread, man! Cool setup! Mine is a little different, and I would encourage you to post your setup in my thread: Power Users: Post Your Optimal Setup!. This way we can create a repository of useful setups for different MXP users. I hope you take the time to do so, and thank you for posting!
Battery and heating problem
am using squid kernel with DU in my cell .... since from last some days am facing problems such as battery draining and heating problem.
can you help me to solve this ??

Its because of the hispeed_freq that they set to the max 1651MHz. Its causing heating issues because your cpu constantly bumped to the max when you use your phone. Just switch it back to 1113MHz in kernel adiutor to reduce the heating.
