Can anyone explain to me what kernels are what is their function? I noticed that the update did not change my kernel. Is that a bad thing that they did not include a new one in the update? Also I am voinv to be installing xboarxers stock. Rom first to root the phone and I want know if I should chance the kernal and what effect it will have. I am taking small steps because want to understand what I am doing. Thank for any help you guys can give me.

The kernel is the lowest point in the system. It controls how the software communicates with the hardware: how the CPU behaves, how the buttons behave, how the screen functions, etc.
The main use of custom kernels is to Overclock and Undervolt. OC means pushing your CPU to be faster than it was ever intended to be; you get better performance but if overclocked too long, it will be damaged. Worst case scenario, you will literally melt your motherboard. But this is only a danger if you leave it overclocked 24/7 and constantly push the CPU to its limits (playing 3d games for instance)
Faux's kernel can OC to 1.5 GHz and Morfic's can OC to 1.1.
The next common use is Undervolting, which means giving your CPU less electricity than it would like. This again is extremely dangerous if not done properly, but yields noticeably better battery life. Morfic's is the best for UV IMO, though you cannot change the undervolting, he has it locked into what he has found to be the best. And this isn't necessarily a bad thing, as too much UVing will cause potentially serious stability issues with the device. It's not nearly as dangerous as improper OCing (it won't permanently ruin the hardware) but it is a danger. Faux's lets you UV to your heart's content.
Faux's is better if you want performance, because it has higher OC. Morfic's is better if you want battery life, because it has better UV and the CPU clock speeds themselves are better tuned for lower speeds than higher ones.
I absolutely love my faux kernel. its at 1.4 and amazing battery life. The screen sensitivity is awesome. Honestly its all prefrence.... I won't go away from cm7w/ faux

Can you flash faux kernel on top of bionix 2
Sent from my HTC Sensation Z710e using XDA App
When you flash a kernel, you just need to know what the base of it is to pick the proper one. There are really only 3 bases at the moment:
1. Stock 2.2 That'd be faux's .5, and I know morfic has some older 2.2 based kernels in his thread.
2. Stock 2.3 (Which faux is working on now, there are a couple floating around)
3. CM7 Faux and morfic both have kernels that work here. (2.3.4 and 2.3.5 based roms use this, miui, and of course cm7 )
Bionix is based on 2.2 (Which I haven't actually checked, but I'm sure it's in the first post.)
For most of them, just read the first post, or even the title. It'll say what it's based on, and then you can flash whatever you want. Just always do a nandroid backup before, you never know if you might for whatever reason have to flash back. If you don't, you need to reinstall your rom (or manually change the kernel and modules, of course) to get back to what the rom came with.
Happy flashing.
If i am running stock rooted GB OTA, can I flash faux's latest Kernel 006 with ext4?? Or do you have to have an ext4 rom to be able to flash ext4 kernels?
Thanks.
Thanks a lot that shed some light on. The subject
So it appears that the dev will tell you which mernels arw compatible with their rom in the thread for that particilar rom. If I want to use eglesblood which is 2.3.4 or.5 xan I use tbe stock kernel? Also what is the difference between the .3 .4 and .5 in the gingerbread make is that carrier specific or moel specific like the blackbwrry 8520 is for tmo and 8530 is for sprint?
Sent from my LG-P999 using XDA App
2.3.4 and 2.3.5 are based on cm7 code, so you'd use the cm7 based kernel. (LG hasn't given us 2.3.4 or 2.3.5).
As far as ext4, it's a different file system is all. Faux's kernels mount the data and system partitions as ext4, but don't actually convert them. Morfic's do a full convert. Ext3/4 support is in the kernel, not the rom, so as long as the kernel supports it you can do it. (Which every custom kernel I've seen supports ext4)
If you want more information, google is your friend. Here is a pretty simplistic explanation of the ext2,3,and 4.
http://www.thegeekstuff.com/2011/05/ext2-ext3-ext4/
As for the differences, 2.3.3 to 2.3.4 had some major framework changes. 2.3.4 to 2.3.5 seems to be only minor bugfixes. If you want full changelogs, I'd google them.
So if I want to use eglesblood then I have to change the kernel too? Do I have to do it separately or is it included in the rom?
Sent from my LG-P999 using XDA App
You never *need* to change kernels. Using the kernel that comes with the roms works just fine. Only time you need to change kernels is if you want to overclock, (never really saw the point in it, and quadrant benchmarks are useless.) want tun or cifs support, undervolting, ext4, etc.
If you don't need any of those things, or don't know what they are, just stick with the kernel that comes with the rom.
Okay that's cool so all I have to do is put EB on my SD card and flash away I am thinking about starting simple first with either xboarders stock or tweeked

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.

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.

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).

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.

but i just want to know which combination of roms and kernels will give me a great battery life and at the same time i want to be able to overclock to 1.5 GHz
i looked through the forums and i did all the basic stuff like
undervolting
setting profiles in setcpu
and removing all the bloatware from the phone
but everyone has a different combination and im really confused as to which combination to use
right now im using eaglesblood 2.3.7 with the dragon kernel and its really not working very well
so any and all help will be appreciated

My opinion:
1. Jump on a stock-based ROM with stock kernel and UC (underclock to 900-800 Mhz, you would be surprised you notice very little change in performance). Most stock-based ROM users report back great battery life.
2. Jump on a CM7 Nightly 199 or higher (Reports of great battery life, I can attest to this) with morfic or faux123's kernel (I prefer morfic's) which you can undervolt easily with Pimp My CPU (search XDA). I prefer it to SetCPU because the only profile I use is UC when the screen is off and with Tegra's DVFS CPU governor, it already does a good job of doing this. I also UC with this setup.
Delete Wi-Fi Calling (Kineto.apk) from your phone if you're not using it. I learned this from lotherius, it's always running in the background even when off and not in use. I was shocked to see the improvement.
I know it sounds stupid, but if you're in class or at work and don't need a barrage of updates on your phone, just turn off data. Most ROMs have a quick toggle setting to efficiently turn it on and off quickly and you'll be quite happy with how long it lasts. If you have to have data on or think it's moronic to have an Android phone that's not does not always have a data connection, battery drain is just the price that is payed.
woah.
Awesome answer
so do you think option 1 is better or 2?
does using cm decrease the battery efficiency?
if it does do you think the extra functionality in cm makes up for the batteryloss?
Thanks btw
Try miui 1.11.4 from whitehawkx with faux kernel cm-4.4

Good question, and I think that is totally up to you.
For example, my father and I both own G2x's, he runs a modified stock ROM (xboarder's ROM) and I run CM7. Without a doubt he gets better battery life than me, but at the cost of not having the features I have.
That may be a rough way of putting it but yes, using CM7 with all it's awesome features come with the price of not being as battery efficient.
The real question is if being less "battery efficient" actually means it's a bad thing. In my case it doesn't matter to me at all. Using the quick panel toggles in CM7, I only turn on data when I need it and I easily pull 15+ hours a charge because of it, assuming moderate usage.
Consider lotherius's tsugi rom, currently in version beta 3. It is my daily driver, stable, faster than 2.3.3 based roms, and excellent battery life. He has included a 2G toggle app that can automatically switch to 2g radio when screen is off to save lots of juice.

Custom kernels provide improvements, tweaks and more power to the user.
Some provide patches to use certain mods... E.g. Multirom patched kernels
Others allow your phone to be overclocked and undervolted. (Both CPU & GPU)
Some just save more battery than others, some have display tweaks included allowing the user to copy Samsung's saturated screens or even lower saturation.
Remember, not all kernels are compatible with all roms.
Read on the bases of the roms and kernel compatibility!
Happy flashing and good luck!

There are a LOT out there that are really good, although the App Viper4Android will always reign superior!
I do recommend you have a look at some of the kernels.
You can get 150% out of your battery with the right rom/kernel combo and probably more if you sacrifice some performance.
Just saying it's something a lot of people don't experiment with, I personally am a flash-aholic and need to flash new kernels and roms every other day!

battery life is dependant on how you personally use your phone, how you set it up, what apps you use, and the quality of your phone/data connection. everything else, including kernels, play a very minor role in battery.

Not necessarily, depending on the govenor (that comes with the kernel) your phone can idle better and some kernels have adjustments to the LMK (LowMemoryKiller) which handles background apps differently.
So in my opinion with the same usage and different handling of background apps, including undervolting and a battery saving governor.
You could easily hit 150% of the usual battery life,
Kernels play in that matter a HUGE role.
You could even throw in some display tweaks (in the battery's favour).

first off, your "battery saving" govornor doesnt exist. it would depend on exactly what you are doing with the phone. the governor doesnt save battery, it tells your cpu how to behave with the incoming need. and they dont control how your phone idle. i use ondemand, and i doubt many phones idle better than mine.
undervolting DOES NOT save you battery, it can even use more than if not undervolted. the only benefit you will get from undervolting is a little less heat.
and again, kernels do not play a role in battery. if they did, every single person would be using the same battery saving kernel. but we are not. with every single kernel someone will have great battery, and someome will have terrible battery. that's because how ypu use it and your quality phone/data connection pre-decides what your battery will be like.
what you are believing are rumors. stuff people dont really know much about, but still keep repeating the non truth over and over. in reality, kernels have almost no influence in battery.
and btw, everything you can control with a custom kernel, you can with the stock kernel. and people get just as great battery on stock than on a custom kernel.
and yes, i do know what im talking about, ive been part of trinity kernel for 5 years now. and ive helped thousands with android and android related issues, including battery.

please, again, i didnt mean offence. im just trying to pass the truth around, thats all. its just that this kind of thing isnt an opinion, there is a truth and a false here. id never go against any persons opinion if it was just about opinion.
Yeah....at best....just changing from one kernel to another MAY affect your battery about 5 to 10 percent one way or the other. In other words.....the direct affect on battery is minimal.
The biggest myth in the threads are that rom/kernel combos make big differences in battery life.
Simply put, they don't.
And everything @simms22 said. ?
---------- Post added at 07:59 PM ---------- Previous post was at 07:57 PM ----------
And in modern devices anyway....undervolting does nothing but keep heat down a bit.....and under clocking has an extremely minor affect as well.
Don't believe, try it and see. ?
I get the same battery life on any ROM....any kernel.
You can make your own ultra powersaving mode or your own hyper performance mode...
I'm just using custom kernel for gamma control, s2w/s2s (which is very useful for me when reading some articles on Chrome), also for USB OTG mounting. Oh oh, and also for killing time, you know messing up with frequency and stuff lol
Well, personally I never believe about the effect on battery life by using this or that kernel since there are lots of things that can affect your battery life, and for my case data connection is the battery killer :angel:
What are you guys talking about??. No, I'm not a kernel dev BUT I have tried so many ROM's and kernels on different devices for a long time now and by experience I can say that they DO influence battery life. I have seen %~50 increase (compared to stock) and aso have experienced just 4 hours of battery because a buggy kernel patch.
They're not placebo when your device start to last 19 hours instead of just 13 like it did since you bought It.

your cpu is set up differently with the custom kernel. thats why. its not the kernel itself. you can set up your cpu on stock so itll be like the custom kernel. its very easy if you are familiar with a few scripts and the root filesystems. for example, i run trinity kernel. with the way trinity kernel sets up my cpu, i get better than stock kernel in battery. trinity set my cpu to run all four cores always on, no hotplugging. it also disables mpdecision. i can set up the stock kernel that way as well. i can do it using a root file explorer, manually, or i can do it via script. and i do know people that run the stock kernel that just get fabulous battery life.
---------- Post added at 10:21 PM ---------- Previous post was at 09:55 PM ----------
there are things that you can do with kernel control apps as well.
Sometimes when you flash a kernel...and many times we flash a ROM right before.....you are only getting rid of a battery issue you previously had before you flashed. So with the clean start, of course you're battery will be much better (especially if you had an unfixed or unnoticed issue before)....and sorry to put it this way, but don't know how else to put it....but the less knowledgeable people think its the new kernel that's made such a huge. Pretty much all the most experienced people know kernels don't make a very big difference to battery life. You can flash clean stock with stock kernel and see a huge gain too if you had an issue before.
Test it yourselves. Flash your favorite ROM and some kernel one day. Go a few battery cycles without changing much or installing much. Then flash the same ROM and another kernel. Same changes and same few apps. And so on...
Eventually you'll get the point.

Eventually you'll get the point.

That right!
It's all about how you feel about your devices.

your cpu is set up differently with the custom kernel. thats why. its not the kernel itself. you can set up your cpu on stock so itll be like the custom kernel. its very easy if you are familiar with a few scripts and the root filesystems. for example, i run trinity kernel. with the way trinity kernel sets up my cpu, i get better than stock kernel in battery. trinity set my cpu to run all four cores always on, no hotplugging. it also disables mpdecision. i can set up the stock kernel that way as well. i can do it using a root file explorer, manually, or i can do it via script. and i do know people that run the stock kernel that just get fabulous battery life.

there are things that you can do with kernel control apps as well.

Ok man whatever, I don't like to argue about the color of the sky so.. Yeah..
Also, I think you should e-mail all the kernel devs and tell them that they're full of bs and that they all are wasting their time improving nothing. You should try to reach Linus Torvalds and tell him that he has to stop developing worthless software, that we all can mod our systems the way we want'em to behave and that we don't need support for newer technology. :good:

It's a good job YOU know what you're talking about, otherwise this thread would have been worthless
The point is you can do some customizations with custom kernels. Gamma control, usb fast charge, etc etc.
But battery life? I never see the difference even with the similar usage that I always do every single day, really, I'm living in Indonesia and the data connection is the battery killer that makes me swearing aaaaall the time lol
I have tried that kernel this kernel (except caf kernel), you name it, but still nothing different, except each of them has their own characteristics.
My own solution? I bought a powerbank, that's my magic pill when my phone is out of battery.
Please, don't think I'm bashing kernel devs out there, they do fantastic job with their creations and I hope they don't stop doing that, I myself using ElementalX, because I need the features that the dev offers to user like me.
Sorry if my English is that bad :/
