What is your preference for Jelly Bean Kernel - AT&T Samsung Galaxy S II Skyrocket SGH-I727

So I have not much time to experiment with Kernels rights now. I have tried thomas.rains and Dagr8's kernel.
From people's experience. Which of the three Kernels (I forgot to mention flapjaxx) do you think gives better battery life in idle state and screen on state? I know on Dagr8 in Badass governor, I have been getting 18 hours with medium use and 20% battery remaining. I just flashed thomas.raines kernel today, so I will test out the battery performance with my daily use.

I've recently started using the Lightning Zap! kernel as part of the Nibbles ROM. It doesn't have as many governor choices as some other kernels, but I've found it thus far to be solid and with fantastic battery performance.

That's great. I help others can get back. How did it compare with other kernels?
Edit** I realized how vague this questions was. In terms of performance and battery life, do you think it is better?
I know each kernel has it's strength and weakness, but just strictly in terms that I will not overclock and I want the best battery life and best performance, which kernel do you think give the whole package?

In also installed Nibble a couple of days ago, two kernel options, can't remember the exact name of the kernel I chose, it had a Zap in it, and it was version 3.
I had used Sean's on ICS, and was going to go to Sean's JB, but I started reading threads and liked what I read about this ROM.
It is the most stable ROM I've ever installed, and with the clock slowed down to 1,026, conservative governor and other power tweaks, I'm getting the best battery life I've ever gotten on any rom on this phone.
Very Very pleased. Install and donate!

In my experience the kernel doesn't make THAT much difference with battery life. I manage mine through controlling what's allowed to sync, disabling refresh in social apps, etc. The Lightning Zap kernel does a good balance of perf/batt without any need to tweak anything, but you can always try the KO kernel instead and tweak the governors, etc to your heart's content.

Best kernel to keep things simple, stable

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.

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.

[Q] Battery efficient rom+kernel?

hi
sorry for being such a nooby mcnooby-pants
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
thank you

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.

What is best ROM for performance and decent battery by your own experience?

Title says it all, I'm currently using PA and I'm not satisfied with performance.
none
try a different kernel. performance and battery doesn't come from Roms. performance from kernels, battery from your use. battery life all depends on your personal use, your personal setup, your apps installed, and the quality of your phone/data signal. everything else is minor battery-wise.

"Best" ROM.
There is no such thing as a best ROM. The question itself is ambiguous. "Best" is obviously a subjective term.
What I want from a ROM may well differ from what you want from a ROM, ergo - what is best for me could be worst for you.
If you are asking what the most popular ROMs are, or which ROMs people are using, you can see which threads stay around on the first few.pages (and have the most posts) in the Android Development or Original Android Development
forums. You can also see what other people are running by reading the What are you running on your Nexus 5 thread.
If you are asking which is the most stable, being a Nexus device - they're all pretty stable.
If you are asking which is best on Battery, ROMs only affect battery if they have a feature that is badly coded. You will likely be able to read about this in the ROM threads. ROMs do not impact battery life. The only impact to battery life are your apps, your settings, how you use the phone and mostly, environmental issues such as Phone Signal.
For tips about improving battery life, please read [Battery Life Help] Troubleshoot battery issues here!
"Best" Kernel
Also, please note that as above, "best" is still subjective. What we*all want from a kernel is different. Again, many people have the*misconception that Kernels affect battery life. Let's get this cleared up. Although Kernel devs will build in optimisations and efficiencies that will improve battery life, these are very, VERY tiny...and if 1 kernel has these optimisations, they likely all have.
People will often say "Kernel x is better than kernel y for battery life". This is actually wrong. Kernels respond to user settings. Setting up the governor to favour either battery life or performance is simple enough to do, you just have to do some learning. The reason people think Kernel x is better than y is because developers set their kernels up with their preferred governor settings. This is what we refer to as out-of-the-box settings. The out-of-the-box settings for kernel x may well produce better battery results than the out-of-the-box settings for kernel y, which favour performance. The fact is, you as the user have the ability to tune kernel x or y to perform the same, be that battery or performance - so start learning how to do this yourselves - that way, you can choose the kernel based on the FEATURES you want, and not the fictional performance benefits of one kernel over another.
Hope this helps

Kernel for stock ROM 5.0

Hey guys.. Returned after a long time on XDA.. Was using unrooted nexus since a year now..
Planning to unlock bootloader and get a custom kernel for my n5 currently on lollipop having LRX210..
Which would be the best kernel for stock ROM..?

Which kernel

Hi,
Should I root my nexus 5?
I still have a year warranty so...
Which kernel should I flash then : Franco Kernel, or Code Blue Kernel?
I am running lollipop 5.0.1 stock right now. Screen on 1/4 brightness, no location and WiFi turned off when I don't use it. Know I am getting around 12h battery life with 2-3h screen on time, would one of the kernels help with battery life? And how much? Will it be worth to void my guarantee for it?
Thanks in advance!
