[Q]Which Kernel are you using?

Hello All!
I made a similar thread to this over at the SGSII forums and was wondering what your answers are. So, the question is simple, which Kernel are you using and is the battery decent? Or a pile of rubbish? Lemme know. Poll has been setup with the main Kernels, I'll put an "other" option for people who are using new Kernels.
So, poll away!

was using James Bond kernel 1.35 OC UV, never crash or lag. far better battery life than stock and super smooth.
right now i am testing faux123's kernel V9u for 4.0.2.

I tried Faux 4.0.3 Kernel yesterday, battery was losing 2% every 30 mins on idle, with next to 0 apps installed.

Running Stock AOKP Milestone 2 kernel, whichever kernel that is!
I wanna try different kernel but my ROM is perfect, not sure sure what other kernels may add that my rom already has and does.

As far as features go, Franco.Kernel adds color and vibrance to your screen. Its also tweakable so you can customize the color settings as you please. Battery is apparently awful though.

thank u. just flashed that kernel, latest. but i dont see color control option anywhere... its supposed to be built in the kernel but i dont see it...
unless i have to pay for the app he has which i dont wanna just for a color change.
am i just blind, not seing that option arggh

I am sort of noticing that battery life isn't so great too, although I wasn't sure since I haven't been running it for very long.

I was also looking for the best kernel.
Everybody talks about franco.Kernel. I will give it a try though.

Was using Franco's until earlier and now back to the Apex kernel that comes with bigxie's AOSP build

Eh? Franco kernel has the best battery life for me.

I just loaded on Lean kernel yesterday. Initial indications are that the battery life is extremely good.
180mhz cpu while screen off = happy battery.

Giving glaDOS a try.. it has some cool features like turn the screen on by touching it.. also has color control and battery life seems pretty decent so far. Big fan of imoseyon though.
Sent from my Galaxy Nexus using xda premium

I'm currently on Bigxie Build 8 with the Kernel included with it. Battery is pretty good. Underclocked my CPU to 970MHz. Losing 2% battery overnight (About 8 hours) and High usage I'm getting a decent amount of battery.

I'm wondering: I'm running ARHD 2.1.3 and thinking about flashing a kernel. Franco's had more options, but I'm getting that Jame Bonds kernel has a better battery life. That appeals to me. edit: ah, I see that Franco's is only for 4.0.3
Still, when I flash the kernel with ARHD 2.1.3 running, is it better to flash the anykernel.zip or should I just flash the original kernel?

Argh, just in the fun, looking for the best kernel. I'm between Franco's and Der Kernel Trinity NP (by the way, NP, Google, don't let Samsung impose it's boring naming system)
Trinity offers 512OC for the GPU, but I'd say Franco gives a better battery life....
Hmmmm difficult decision, isn't it? What do you guys think?

Currently rocking the Trinity kernel with mildly OC'd GPU (384 MHz).

I'm using imoseyon's kernel. I love minimalist kernels. Stable, fast, and not full of crapfeatures that just cause everything to crash and SOD and bootloop.

I think it's probably a good idea to give a try first of the kernel that comes with the ROM. Developers often adjust the ROM around the kernel they use and vice versa.

i went back to the James Bond kernel, no reboot or lag.

Lean IMO

[Q] Differences between Synergy and Darkside X kernels

I see that some rom developers are currently changing from the darkside kernel to the synergy kernel. I know that synergy has better battery life than Darkside X kernel (or that it should) since Darkside X is much faster and smoother.
1. But is the battery life of Darkside X kernel significantly lower or just a little lower than the synergy kernel?
2. Also, what are some features that the synergy kernel offers that the Darkside X kernel doesn't, and vice versa?
Thanks!

Bro i read somewhere before NEVER COMPARE TWO ROMS OR KARNELS OF TWO DIFFERENT DEVS . ITS JUST AN INSULT OF THEM.THEY ARE GOOD ON THEIR OWN WAY .
Not being mean rude but telling you truth i have learn.

neither is better than the other. One gives you better battery life while the other gives you better performance. Its a trade off. both are good in there own way. I just want to know if there are features one has that the other doesn't. And does synergy beat darkside in battery life by a lot or a little.

Generally speaking your mileage will vary with everything. ROMs, kernels, whatever. I personally get better battery life with darksidex and smoother performance with synergy. Most of it is probably placebo either way.

Flash and find out every phone is different.

synergy supports almost every governor. this only will matter to you if you know what a governor is...
darkside is more noob friendly. also, if u are running a darkside rom, do not use a diff kernel.
Sent from my SGH-T989 using XDA

u can use any kernel on any rom, (CM7 excluded). As others have said different kernels support different things, and may or may not be better for u given your needs. If u stress battery life, governor options in synergy will help u with that, finding the best balance between scaling and performance. Dark side may be better for gaming. All comes down to user preference

Synergy doesn't have all the sophisticated bells and whistles like swapping cache and page serving stow away performance like DS or any kernel with ram appreciating software. So to speak it's software for better page cruising experience.

[Q] GNexus Kernel Choice

Loving my GNex, however I've only had it a couple weeks.
There are several kernels out there, and from comparing all of them and reading all the threads as much as I can, they all seem to have relatively similar features... I'm having a hard time picking one.
Is there someone who can clarify the differentiating features of each kernel? Are certain kernels better suited for different ROMs? Do certain ones have compatibility or other persistent issues?
Mainly:
faux123
franco
GlaDOS
jamesbond
Trinity
I've tried faux123 015m (loved faux's kernels on the Sensation, but I had some mobile data issues with it on the GN) and Trinity (latest seems fast/stable, except the color profile was messing with me). I'm trying GlaDOS now. Again, though, I'm not sure what advantages or perks one kernel flavor gives me over the next. Can anyone shed some light?

I have tried them all myself at one time or another and i always come back to GLaDOS. I chose to run this because of the unique and innovative features Ezekeel has developed plus the great battery life. BLX, Vibration control, Touch Wake and of course the Wheatley Governor which was developed for this kernel to give the best performance and battery life, which in fact it does. The GLaDOS control app is great too and Ezekeel is always updating and making it better.
GLaDOS is exclusive to Rootzwiki that why you don't see too much mention of it here unfortunately ... I'm not even sure if Ezekeel lurks around here anymore?

Thanks for your responses!
However it looks like people are just posting what they use. What I'm looking for is information on what differentiates each kernel.. what is each kernel's "claim to fame"? From what I've seen, all of the kernels' features look pretty similar.
For example, "X kernel balance performance and battery really well. Y kernel reduces the voltage to the screen to further battery savings. Z kernel is more focused on performance. A kernel allows your phone to make popcorn." etc.
Or are they basically the same?
Thanks blowtorch for giving some information as to what differentiates GlaDOS from the rest

Jamesbond will likely give you best battery life and stability. He has a couple of other kernels with some performance boost. Glados was buggy as hell and some other things but that is for you to decide. Other kernels for me were kind of meh. I honestly dont understand how so many people say this kernel or that kernel is the best or best on battery life when so many tweaks in X kernel add more performance at the cost of mah. I liked glados and its features a lot but it came at a cost too high. Touchwake is a really nice feature in it and i am surprised more people don't ask for it. Another kernel i liked was bamf paradigm but i am not using it. I would like to try that rom again in the future but it wasnt ready for me personally. Havent tried franco's at all. Just seems to be feature packed kernel but for what?

I like francos so far works great with my favorite rom AOKP, buttery smooth, stable as hell, you can go battery saver or performance since you can OC/UV, etc, if you buy the App in play store it works great cuz he updates the kernel oftem and you can use either milestone versions or nihgtlies, and has the option for autodownload and autoflash the lastests updates.
You can change screen color values, as i said oc/uv, change the boot animation, and plenty other stuff..
Thats my 2 cents on your research
Edit: forgot to tell you, he also has a support mail , and if you have any issue kernel related he will answer with a solution if possible.. Report bugs etc

I've been using GlaDOS for the last couple days and haven't had any of these issues. Bluetooth is working perfectly, even over my car's hands-free setup which has been problematic with some kernels, and audio is working perfectly... maybe you were on an older build?
Anyone have any other info? I'm surprised nobody has said anything about faux or Trinity..

Well I guess I'll be the first to represent faux kernel over here. Like that its not over done and no special app is needed to control it and the gamma control from panda board he forward ported is pretty slick if you ask me

Trinity is legendary ... never got around to faux
I'm sticking with CM9 Kernel for now it's as good as the rest IMO plus they are integrating more and more into it ... missing touch wake though from GLaDOS, oh well
I'm mainly looking for battery life now. I don't really notice much difference between most of these kernels in terms of battery life. All of these kernels have good performance without overclocking.
I find that i bounce around from kernel to kernel and in the end when all is said and done no kernel is better than the other and it really comes down to preference.

Rom most note 2 users are using

Hey all,
Just wondering what rom people on this forum are using on their note 2.
Also, if the sound recording is an issue on official cm nightlies, does that mean all roms based on it like the unofficial, or vanilla rootbox, liquidsmooth have the same problem? Because they are based on also?
Thanks for your time

maybe it's time we run a poll for all the roms out there?
I bind around between a bunch, but I spend most time on the Jedi series

check the development section to see what roms people are using
and, yes, any problems that cm 10.1 has, any rom based on it most likely will have..

It's not easy to do an actual poll on here. At best you'll get pages and pages of people listing roms. No value add, no data collection or analysis. So yes, the easiest way to see what people are using is look at the roms available. And lots of people flash roms like some of us shower; what they use today may not be what they use tomorrow.

AOKP or ROOT-BOX

I've been testing out a bunch of ROMs that go by just to see what works and what is needed to be fix (let's face it... that's what this site is for... It's a developer's site that lets us alpha/beta test out their skills and report what needs to be fixed). Each ROM has their unique features and such.
It's not a popularity contest, so no, I don't think there should be a poll since it will not matter. What does matter is if you find yourself a ROM you like, support it, support the developer by saying thanks and if you can, donate. Don't be afraid to try other ROMs as well. I've said this before and I will say it again... You have nothing to lose but a bit of time depending on how much you make a ROM your home. Find which one works for you.
Nandroid backup, wipe, flash, test. Like? Say so. Something broken that hasn't been reported yet? Say so.
Try not to treat this site as a free custom workshop for your phone. Treat it as a test site and be happy the devs take the time to do these things for us users/testers.

So I have tried most all of the top 6 ROMs. Clean Rom is very stable, Jelly Thunder has nice eye candy, but hands down the best ROM for me is SkyNote 7, aka Sky Wallet. Love the light saber sound for s pen. I worked with Seanz testing wallet, so I KNOW it works. I did put the latest Perseus kernel, Awesome beats, and Apex launcher on it to customize. IMO, this ROM is the pinnacle of Note 2 development!:silly:

Cleanrom is my choice.

I've been on CleanROM for a while, but right now am trying Jedi XPX.
CleanROM is a very safe ROM to use. It's as close to stock as you can get. Hard to quantify exactly how much better performance and battery life are, but my impression is that it is better than stock. Nothing that blew my mind, but when the Note 2 is such a beast from the start, it's hard to say that it is, or isn't a vast improvement. This ROM also pairs well with a couple of custom kernels (Perseus and Saber are the ones I've tried). One awesome thing about that the developer of CleanROM does is package it with Aroma installer, which allows you to pick and choose what you want in the ROM.
I've only had Jedi XPX installed for a couple of hours and so far, it's really good. Seems to be smoother, but I can't really say with absolute certainty. You'll love this ROM if you're a Star Wars fan as the developer integrated some Star Wars soundbites with some of the actions. The developer also added his/her personal touches like having "Jedi X" at the bottom of the lock screen and "Deviant Development" on the notification bar as you're swiping it down. Personally, I don't care for it. As I've just loaded it, I can't really say much about battery life yet.
Seems to me that you really can't go wrong with the two I've mentioned above and the developers are active in supporting their ROMs.

JediXPX is the best fit for me, the battery life is just insane with his Saber Kernel........its stable as ****, and runs super smooth. i have been on it since Jedi 3. something or other.
i have tried them all as well, not just the top 6 and Jedi seems to be the one that has them all beat in my OP anyway. but there works of art so pick one and run away.

Skynote for me

JediXPX is the smoothest ROM I have ever used. And I go through a lot of roms lol

N7105XXDMA6 is what I've decided to stick with for now.
Paired with Perseus kernel seem to do really well for me. I love AOSP roms but can not stand the absence of the S-Pen/S-Note features, then again, there are mods for N7105XXDMA6 that have allowed me to mimic CM 10.1 very closely with color scheme, features, CRT animation....all that good stuff!

After going through about 6 ROMs and trying them out for a day or two. The one I have settled on is Paranoid Android 3.00 for the N7105. The vast majority of this ROM is flawless. Super smooth running with zero lag, lockscreen or otherwise. PA-Colors is a really cool feature. I thought i wasn't going to care but it really evolves they seemlessnes when switching between apps, the notification bar fades into each one and is completely customizable. Photosphere doesn't work just yet. But I expect that to come in a few updates or so.
I simply hate touch-wiz. I hope I'm not alone in feeling that way. Also, after coming the the i717 running Slimbean, the stock DPI is just way to huge looking. Touch-wiz and the stock DPI doesn't make good use of the size of the screen. I like being able to scale down the entire DPI and make it look like I'm not looking at it through a magnifying glass.
Honestly I will say that I may not completely understand the power of the S-Pen but it has enough functionality in non-touchwiz roms that i don't notice it lacking. But I do miss multi window, I really do.
Im open to suggestions and skyrocket intrigues me. I think im going to check it out.
*end rant*

The Jedi series is top notch. My personal favorite. A very good stock rom but added a few things to give it a different feel. Love it.

Jedi is really a beast. Great Bergey life and smooth as silk. Also something g that is super important very little problems and very stable. I have flashed other rooms but nothing else gave this combination. The saber kernel is amazing also. Quite a few themes that are not even built for this tomorrow flash well with it.
I have ever recently just starting g reading up on Jdevil rom and it seems to be getting rave reviews for speed and battery. It is based on the new international base and said to be super fast. People are getting huge quad scores without even oc. Something to keep an eye on.

Which kernel do you prefer for best battery backup?

I am not asking which one is the best, but which one would you prefer for best battery backup? Samsung's latest release is forcing me to use a custom kernel, but I'd like to know which one I should use as I am not freak about flashing plenty stuffs.
Thanks in advance.

Redpill or uneak or perseus. You can try them all.
Sent from my GT-N7100 using xda app-developers app

Yeah, but I don't want to try them all bro. I know they all are great but that's why I asked which one is the preferable for battery backup specifically.
I am on Perseus now, I hope I've made the right choice. Lets see...

Persues is good for battery.neak is battery drainer.my experience

You're not asking which ones the best, but I'll tell you. I have used all the available kernels for my Note 2, and in my experience RedPill is the only one that is giving me consistent and best battery and overall performance. With more and more updates the developer has been adding more and more options. You can also undervolt the CPU and GPU with RedPill for further enhance your battery life. I had huge battery problems on my S3, So i had to go through a bunch of crap like different custom roms, undervolting, under-clocking etc to achieve good battery life. But when i got my Note 2 i used it for a few days completely stock and un-modified. And i was surprised at how amazing the battery life was. But if your having problems i can recommend AllianceRom + RedPill kernel, than undervolt the CPU/GPU (The utility needed to do so comes with the kernel, after flashing there will be an app installed on the phone called STweaks). And do some other minor adjustments to achieve incredible battery life. If you need any help or additional information you can contact me anytime.

I also want to know...
I would also like to know this as well. Since upgrading to 4.1.2 I am having bad battery backup, never thought of switching kernels but now I have to.
Shame on you Samsung....
