Best Kernel?

So i've been reading up on some kernels. Specifically the ones where they seem to give good battery and stability. Overall it seems the Trinity is most stable, while Franco's is also about the same. However which of these two kernels do you feel that are more stable?

LeanKernel the best battery life and good stability.

i've been trying many kernels for my GN and i totally agreed: in my specific case AOKP+LeanKernel+LeanKernelTweaks=absolutely the best so far!

There are many opinions about this. Some like franco's, some like Trinity and some Lean.
I tested Franco and Trinity on AOKP M3 and can't catch greate differences. I think the kernerls are all good, but the differences are quite low. Its more a placebo which kernel is the best.
Here you can see battery life on GSM Nexus on AOKP and Trinity Kernel: click me!
PS: Never heard of Lean, can anyone provide a link? Search found nothing ..

franco kernel, batery, performance, stability.. the best !

Lean Kernel.
Best battery life, 4+ screen time hours every time even with all the Netflix and Music I watch and listen to.
It's a minimalistic kernel so you can probably get others which would sacrifice battery life for better performance.

Its on rootzwiki, but there's probably a reason its not here, so I won't post a link! Just Google it....IMO, trinity kernel is the best! Especially the 512 MHz gpu version! Smooth and battery life is great! But it truly depends how u use your phone, how much u put it thru. Everyone varies! The beauty of android is u have options! So go nuts and flash em all and try it out

not the best battery life for me

Franco by far. Best overall battery life, refinement and performance.

TRINITY no doubt. I tested Franco, Lean, Fugu over weeks. Apart from Benchmark all showed worse value than Trinity. Most imortant for me is battery live. I am on push exchange for 24 hours, permanent 3G and GPS, automatic update and WiFi roughly 2-3 hours per day. Besides of that approximately 30-45 calls everyday and 85% roming.
Bettry shows in the evening 40%+. Scaling Governor recently changed from OnDemand to HotPlug. Idle Min CPU 350MHz and Max CPU set t 1200MHz.
Warmly recomend to taste.

I have to say, I've flashed a lot if custom kernels in my Android days. Right now, I'm really loving this kernel by Faux123.

The kernel that comes with AOKP suits me fine. Tried Franco for a while but seems like battery drained faster..

I have been using Manhatten IC ROM since I got my Nexus, using Lean Kernel. Has been working fine for me. But I've installed Francos and bought the Franco Kernel Updater. Using FrancoTurtle governor and raised the CPU to allow 1200Mhz, I am amazed. Battery life is great, the phone is snappy and responsive all round.
Can recommend Francos Kernel.

Franco Kernel 13.1 is so far the pinnacle of the Franco Kernel development. I'd recommend it over the later versions where there have been instabilities galore and decreases in performance/battery life. I've tried many kernels(Trinity and Lean are also good) but always end up returning to 13.1!
Regards.

Well thanks for the reply guys! At the moment I'm testing glados, waiting for Franco's 18 tonight. It looks to me its between Franco and lean kernel

I was going to write the exact same thing. I recently switched from Franco to Lean Kernel and am noticing significant battery improvements. Any idea why the latest editions of Franco seem to provide worse battery life?

James Bond 007. I've gotten all the performance that I've had w/ Franco's and an extra two hours of on screen time with heavy network use.

i thought i was the only one who thought this. but yeah, nothing comes close to franco 13.1.

What kernel do you use?

Just interested. I want a kernel that has good battery life, I have tried franco & cmtuna. I think cmtuna has better battery life than franco, but what do you use.

I use popcorn-kernel and it works very well. Glados and Trinity are great, too.

+1 with Glados kernel
But,to the op...this is a recurring question...Get as many answers as there are different kernel+all the different settings (CPU freq,GPU freq,undervolt,hotplug,etc...)+the rom used+your personnal settings (sync,brightness,widgets,wifi,etc...)+your use...
For me it's impossible to give an answer like that "what's the best kernel"...It depends on to many factors...
Testing other kernel for at least 4/5 days with your usage and see...Take time also to read the feedbacks of the different kernel topics and the changelogs,sometimes it's useful.
A kernel it's not like a full rom,not necessary to do a full wipe each time and loose your settings,etc...So you can flash a kernel easily each 4/5 days and see wich is the best for you,no?
Someone will say xxx kernel is the best for me and after another will say oh no poor battery life with the xxx kernel,same for all other kernel...What do you do?
There is not the kernel alone,which depends of battery life...and that's for sure.
This is a very subjective question, as the answers ...Nothing is known of your usage,your rom, etc. ...You have tested Francisco and ch33kybutt's kernel...and...Battery life is bad,not great,ch33kybutt's kernel better than xxx...And...???
what do you mean by "I want a kernel that has good battery life"...First check your settings for you like I said above,your usage and see...
And guys said good battery life with xxx kernel...just like that, just for a post or...
I have the best battery life with the awesomeincredibleamazinggreat kernel...,I'm happy with 2 hours deep sleep and 5 mins screen-on...awesome...It corresponds to my use and what I hoped!Great great!
Voilà...It depends on how you use your phone and how is for you a good battery life...

I'm using morfic's Trinity kernel. It's the fastest kernel I've tried and battery-life is great, even though the GPU-overclock.

I'm going to go against the grain and say I haven't noticed a significant difference between the kernels. Undervolting doesn't even do much, the processor drain is insignificant compared to the screen.

Is there anyway I can download the stock kernel that came with 4.0.4? This is incase I want to go back, (now running stock rom again)

I'm using the Franco kernel. With the stock kernel I was getting stuttering audio playback when disk I/O was going on. The Franco kernel has some I/O scheduling optimizations that fixed the issue for me.

I have only tried stock, glados, and Franco. Glados would heat up my phone at times, and franco does it less and better battery performance .

I use Franco's kernel. There were some issues with the last couple of nightly builds but they seem to be resolved (at least for me) in the lastest 166. Get his app from the Playstore for ease of configuration.

I use the CMplus, he works with no problems CM9.
Before CMplus, I preferred the Lean Kernel, but CMplus is at the moment my favorit.

i find franco has best blend of battery life and speed

Trinity.

[Q] Highest Stable Overclock? (On JB)

Hello, I'm dumping my most amazing phone ever (Dinc) that I've had since the day it came out because Verizon are greedy *******s, and I just ordered a Gnex GSM from the Google Play Store.
When it arrives, I was wondering what I can expect to achieve via an Overclock and have the system still perform rock solid.
Thanks!

subjective. different for everyone and depends on temp, usage, stability of app youre running etc etc. just bump 5% at a time until you crash then drop it down one notch

You also need to disable smart reflex to hit the higher clock speeds without random freezes or crashes. I am running the trinity kernel at 1520 MHz stable with mpu smart reflex disabled.
Sent from my Galaxy Nexus using xda premium

i can't provide any input on overclocking because this phone performs so well without it that i haven't found a need to. plus, the battery life is bad enough.

really, its different for every phone. I run 1.804ghz(trinity) stable after a little voltage adjustment. and you would have to turn off smart reflex for that. you will have t read up about smart reflex.

As said above it varies. Fastest I ran that was stable (at least for me) was 1.9 GHz (Franco Kernel) but there wasn't much benefit. I'm currently on Trinity at 1.4 GHz. Trinity on 1.7 GHz crashes for me.

I can get 1500 MHz on faux kernel, 1800 crashes me

Out of interest for you guys on 1.8/1.9Ghz, what do you have yours so high for? Games? Just interested as I actually have mine UNDERCLOCKED to 1096 and have no 'real world' use for anymore. Mind you, I'm not a big gamer so I wouldn't know how the nexus really handles 3d gaming.

Sent from my Galaxy Nexus using xda premium

With Trinity kernel for JB, I'd guess that 1420MHz CPU / 384MHz GPU would be stable for most phones, and it gives you a good little boost in benchmarks, fwiw. That's about the highest you can run without having to remember to tweak other values. And you can knock it down to 1036 or 1190 MHz if you need to save battery. My phone tests ok with the 15xx/5xx MHz kernel, but there isn't much additional oomph in the benchmarks, so I just use the 1420. Also don't want to abuse my phone too much.

Well the faster CPU helps with n64 emulation some games need a bit more omph to play smooth

Gnex overclock
I have overclocked my Gnex to 1.6 with the glados kernel and using the glados control app it's very stable. I tried 1.8 but crashes but I would highly recommend glados very stable at 1.6 and runs a quadrant score in the 2800's

Congrats on dumping Verizon. They are the worst. I am happy to be rid of them. Trinity 1344 and Franco Milestone 5 have been the most stable for me. I currently am running Franco Milestone 5 at 1536, it's fast and stable. You gotta remember too that this phone is running Jelly Bean and a dual core which will be faster than your Dinc anyways.

You have to see the battery issue as well, if not to its will end quickly! In my opinion, use it in Stock is enough. But sometimes I get to put on 1.4Ghz CPU, and I reduce the voltages using the app franco kernel.

I was running Franco milestone 5 at 1536 nice and stable. I think I'm going to drop it back to stock-ish speeds and undervolt it a bit to save battery.
Sent from my Galaxy Nexus using xda app-developers app

Thanks for all the input everyone.
I guess my last question now would be, if I root and keep the Stock ROM, has anyone experimented overclocking the stock kernel?
And if I decided to install CWM, and keep the stock ROM, would Trinity or Franco work on that? Or would I have to install something like CM10 or AOKP to use those other Kernels.
I would rather just like to stay stock without CWM and overclock the stock kernel.

AOKP JB (Verizon)

I have typically had very good luck with my battery usage, and when I dont I can usually track the source and fix it, however, I am really battling with 4 hour battery life lately. Can anyone suggest a good kernel for this, or maybe some trouble tips.
Thanks in advance.

I'm using the faux kernel it came with and my battery life has been fine. What kernel are you using?
Sent from my Galaxy Nexus using xda app-developers app

Honestly, tried many kernels, such as Trinity, Popcorn, Franco and Faux, but I gotta say, battery life doesn't change too much. What you can do to improve it though, is to undervolt it. Or underclock it if you're ok with that. I also recommend you to use SetCPU to set profiles.

Try Jame Bond kernel.

Best Kernel for Overclocking Galaxy Nexus

I'm thinking of flashing a different kernel to my Samsung Galaxy Nexus so I can overclock the CPU/GPU. I've noticed that franco.Kernel and Trinity seem to be among the most popular kernels, but I'm not sure which one to choose. In your opinion, what is the best kernel for overclocking and why? FWIW, I have the Verizon model of the phone (toro) and am currently running CyanongenMod 4.1.2, which is based off of Android 4.2.2.

Antutu or CF bench are good apps.. And a warning: overclocking will decrease the life of your phone! Be careful! If you want to use your phone a little longer I wouldn't do it (I wouldn't anyway because I think this phone is very fast especially with Android 4.3)..

Hi,
I've decided to bump this thread because all other GNex OC threads are very dated.
I recently received the extended battery 200mah and I'm ready to overclock. I wish to retain battery life to have screen time 3-4 hour on moderate usage.
I'm current rooted on stock ROM, and I wish to simply stay with stock ROM provided battery life will remain the same (perhaps I have to undervolt)
I want to hit 1.5GHz CPU and 384MHz GPU...which is what the OMAP and PowerVR SoC's true default clocks.
Given my circumstances of stock ROM, which kernel would give me the best stability/battery life? Any kernel that somehow has OC settings built in or do they all require me to buy setCPU?

I don't OC myself. I want my gnex to last some longer. OC will wear out tour CPU.. I die it once for a day maybe two but didn't notice any improvement. I was at 1.5 GHz or something.. I think it may have some speed improvements but your battery will drain like a maniac. If you don't game I suggest you underclock: even more battery life with no speed loss!!
