Can anyone tell me the benefits of using a kernel like Trinity or netarchy or matr1x?
I've been searching and basically I want the stability of the stock kernel, but with better battery life. I was eyeing the trinity undervolted kernel but wasn't sure if it would affect anything in terms of FC or performance?
Oh, I'm using MIUI and was reading around and some people have experienced different negative things when using this ROM?
Well other kernels have a lot of features, like oc'ing, uv'ing, bln, voodoo, etc haha
Ohh okay. The only thing I see of benefit for me right now is the undervolting to increase battery life. I mean I haven't met an app that I can't run yet so no point in over clocking.
Unless I'm missing something

I'm kinda new to all this, but what is the difference between changing a kernel versus changing a ROM? or is that the same thing?
for example, i understand backlight notification works on some kernels on the nexus s...does this require changing the ROM? any help would be appreciated
A ROM is basically the custom image (think of it as an os) for your android phone. ROMS are usually based off of stock android or cm7. ROMS allow for differen gui's, etc.
The kernel is basically the piece of software that allows the rom (os) to communicate with the hardware of the phone. You always see things in kernels called "voltages" or cpu speeds...that is set in the kernel, and allows the phone to run at a different cpu speed. Also, you see bln. That communicates with the hardware and allows the back lights to light up when you receive a notification.
That was a simple explanation, but it gets the point across
thank you for that...makes perfect sense... so if I want to just get BLN working, is there a kernel that would work with my stock ROM? or do I have to use the kernel with a specific ROM? I'm still unsure of the steps required to make this happen
Bln is baked into a kernel. Just flash a kernel and u will get bln

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 ...

True, but he prefers to OC it a bit.

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.
U can find it on:

Ouch, your Sensation can't handle 1.728GHz. I'll make a 1.512GHz on boot version (assuming my laptop won't act stupid, it shouldn't take that long) but I'm a little reluctant to add Badass because its primary goal is to save battery, and when I used it my phone went really slow. If enough people agree with you, however, then I'll add it.
UPDATE: 1.512GHz version added in the Download section! Enjoy!
Hthere, can somebody advice if this kernel can be used in SENSE ROM ? Thanks.

This is not for Sense because there are no Sense ROMS based off of Jelly Bean. Even then, this kernel was not designed for Sense ROMS (nor was it designed for Ice Cream Sandwich) and I have not tested it on a Sense ROM. You can still try it on a Sense ROM and see if the Wi-Fi works as I am pretty confident it'll at least boot up.

I've totally agree, badass govenor only for good battery life but not enough good for performance. I never badass govenor to choose for using some kernel. For me ondemamd govenor is the best,give me a balance between battery life and performance. Try downloading,flashing it and report later. Thanks for hardwork.

OK, I've tested in the SENSE ROM, and it WORKS well so far including the WIFI. Thanks and will see if any advantage of this kernel compared with the others.
PS. just found out that the USB connect to PC won't work. I feel this kernel is very smooth and it will be highly appreciated if you can make some modification to make USB work ? Thanks.
I second the installation of badass. I love performance but with that comes battery drain and I use my phone a lot while I'm away from chargers. It would be nice to have a choice to save battery when I know I won't be able to get to a charger for a while.
Thanks for your work.

That could be ROM related. If it isn't ROM related then it's probably due to fact that my kernel isn't designed for Sense. Try installing a different kernel like Bricked to see if USB works. If it works with Bricked and it doesn't work with my kernel then sorry, I can't do anything about it.

Once/if the number of users increases, I'll start a poll asking whether or not badass should be added (maybe a few days to a week from now). Thanks for your feedback

Though I do like badass governor, if the kernel is meant primarily for performance, I for one would like to see OnDemand included. It's always worked well in performance terms for me. Thanks for sharing buddy :good:
Performance governor is just that wide open quick response only if willing to have serious battery drain!
From my personal exp.
Badass,smartass,ondemand,brazilianwax,Lionheart,Wheatley etc. These govorners have a broader range for specific needs!
1152-6 is best overclock and is considered the kernel sweet spot
Anything more beyond this level is more cumbersome and can and will cause freezing in selected devices!
Here is my old kernel got for dev with 20 or so governors he can use if he chooses

tested and comparing with Tamcore kernel
I need help.
I'm a flash-a-holic.
I'm afraid I can not stay on one ROM for longer then a week. ( as there are constant updates)
I have flashed multiple kernels and I never can really tell the difference.
I want to find a great kernel that keeps battery as first priority.
So I was wondering what kernel you use and why.
Edit: it would also be nice if you guys could link the thread of the kernel to your comment so I can further look into it
Thanks for your input in advance guys

yep I'm same way, I play around with the custom kernels, and the devs do an amazing job with them, but for me personally, I don't overclock, or underclock, and have never played with voltages, so I run stock kernel and it rocks for me, 5 hour screen on time running TW CleanROM
Great question, with so many different kernels released all the time it's tough to keep track. I'll definitely follow this thread though
I recently flashed lean kernel 1.7 and it seems like one of the better battery savers. I've tried a couple stock ones as well as Galaxy KOR 2.6. (All of them have been TW kernels btw)

i use lean kernel. most the time with my clean rom.
i have been on galaxy kor but noticed nothing special.
currently i am trying out ziggy and it is nothing to brag about.
dont get me wrong though. i deeply appriciate the hours of work the devs put into all there work. and with the greatest respect. i thank them for all the hard labor.
Ziggy kernel is beastly on battery with SynergyROM. This is standard battery life for me (stock battery):

I am using the CM11 M8 on my Nexus 5. What Kernels are compatible with it? I have been a big fan of CodeBlue and ElementalX but I am not sure if either of these work with CM11.
All CAF Kernels work with CM11. ElementalX works with cm. It has both AOSP and a CAF version. You need to flash the CAF one!

The min frequency isn't stuck. When you touch the screen, flar2 has set the freq going up to around 1200mhz so that there isn't any lag. If it's indeed getting stuck for you, you must have installed a kernel tweaker app which is causing this. Been using ElementalX since ages without a hitch.

Not sure about the kernel in question, but I've absolutely seen SlimKat's kernel do that. No kernel tweaker app, just system monitor.
It seems minor hardware variations can cause only certain people to have issues with certain kernels. Or if there is an issue in the code, can be exacerbated by hardware variations.

Oh I see. I've seen quite a few people who complain about this frequency thing in the ElementalX thread as well and most of them had a tweaker installed so I thought it's an end user's error. You could be right though, not all phones are made the same.
I'm using Latest Chaos nightly. Performance/Battery life is amazing to my usage, so i'm recommending you to give it a chance. ElementalX is good too, but you should try them both for a day or two and then deside which one suits you best. You can grab it there:
http://forum.xda-developers.com/goo...-kernel-chaos-12-0-nxtweaks-app-13-0-t2551441
It's CAF kernel, so it's compatible with Cyanogenmod. Happy flashing
I'm on the latest CM11 nightly with chaos kernel stable 13.1 and I'm loving it. Performance is awesome and I'm right on track for a 5 hour screen on time with heavy usage.
