[Q] Best Battery Saving/Performance Kernel - Nexus 4 Q&A, Help & Troubleshooting

hello im looking to flash a kernel over my current roms kernel but i came from developing on a motorola atrix which had faux123s kernels as the best but i couldnt get the to boot on my s3 and i have no experience with the n4 (got it yesterday)

Personally I'm using franco. It has the best balance for me.

I sometimes wonder if people keep starting these threads simply to troll.
No such thing as best kernel or best ROM. Pick one whose features fit your needs and test it.

i dont have time to extensively test, most kernels i use i notice no diffrence, me personally i keep my processor at 1.026 max with sio and usually interactive as my governor, also some kernels have gpu overclocking and some dont i cant really tell even after sifting through everything, like a good rom i am testing every aosp based rom and i cant find one to really stick out. i am asking opinions i suppose.

can i use the faux control center to mess around with the gpu? if not i may just stick to his but i like franco since it has nightlys
I guess a better question would be should i stick with stable aosp roms and kernels or go with nightlys? if anyone has a suggestion or personal prefrence i would love to hear them, i have pretty muched used xylon and franco nightlys,slimbeans,paranoid android april 26th build and liquid smooth. havent felt the need to try vanillarootbox because from what i remember its cm based anyway

All of the kernels here are great. Try them all and see. Personally I think you should start with Trinity kernel. It has awesome performance.

no one ever gives matr1x credit, but that is definitely my #1.

many people say that franco,trinity or matrix are the best but sometimes the stock kernel as the CM kernel is the best at least for battery.
now if you are gamer etc maybe franco kernel is your best choice!

I agree. I'm using Franco right now. Its able to push through a day of tweeting and whatsapping but stock kernel and cm kernel was amazing. 1% drain after 8 hours of WiFi on standby.

Currently I'm on stock 2.3.7 with Wallet. (I've been wowing everyone at McDonalds and Best Buy with that lol)
I came from the dev failure that was, the Epic 4G.
Matrix or netarchy. I personally use matrix it gives me awesome battery life. But they're different for everyone so you will just have to try them out and see which one works for you.

Trinity. for speed/performance or for battery life, and everything in between. theres a version for all
Apocalypse Talon. Snappy, great battery life. Using it with Cyanogen 7.1. Your mileage may vary.

+1 certainly the best kernel for miui.
Sent from my Nexus S using XDA App
Congrats on your new nexus s. Great device.
As for kernels...well from my experience, i would say netarchy all the way for stability and performance combo. Never had any problems with his kernels. Its got all the usual features such as voltage control, voodoo controls etc. Very stable.
Trinity has been good for some but ive found it too unstable more often than not.
Havent really tried the matrix kernels so cant really say.
Have fun!

Franco kernel is good for cm7 and matr1x kernel is good for almost any rom
Sent from my GT-P7510 using xda premium
I use CM7 Nightly Build#229 (Best build yet) with Matr1x Kernel. But i agree that Trinity is the best Kernel for MIUI.
I highly recommend franco's kernel with custom UV settings and the lazy governor. Netarchy has been on hold recently but looks like it might be back in business soon.
try NSCollab ROM + matr1x or franco's kernel

I have 58% left after 1 day of normal usage with Matr1x kernel with ondemand enabled. I underclocked it to 800Mhz. That's enough to do my everyday stuff. When I game, I put it higher.

Kernel discussion thread

Guys i just wanted to know which kernel is great for battery on ics ?? And till when can we see custom kernels on jb??
Sent from my GT-I9300 using xda app-developers app
You won't see any custom kernels for JB until we get kernel source.. as far as a good kernel for battery..? They all are mate. Every single kernel has at least 1 happy user that gets great battery life. Of coarse mileage is gonna vary. My suggestion is to try em all. Spend a day or two with em and see how they do with your setup. It should be noted that any kernel/ROM combo is gonna need a good day of battery drain and a full charge to really see how she does!

Love it how you use "she" for kernel. :good:
Anyway, I love kernels optimized for battery so I'll share my experience:
phenomenal - One of the best out there, this was built solely for battery. I've been using this in my early ICS days. I could ask nothing more.
siyah - This one is a complete package. You can under/overclock or undervolt CPU and GPU. Has a lot of tweaks, my favorite one is what they called EARGASM. Awesome
galaxsih - I'm currently using this kernel. Aside from battery optimization, there are also some tweaks integrated. Build is almost daily, the developer always update the kernel,
These are just the kernels that I tried so far and these are based from my experience.

Running stock at the moment, had no problems' very snappy.
I like Paranoid Android but almost all are very similar and the devs have done a great job on all the ROMs.

Used codename android and then it became slightly buggy. Running XenonHD and it's smooth and stable. Loving it right now.
Will have to see when 4.2 ROMs get uploaded but so far Xenon finally removed the blue grids around home screens while moving. Left over from tablet UI and I just hate it and CNA still has it.. Don't want to use alternative launchers either.

I feel they are all about the same. PA really is in a league of it's own if you want to utilize their features.
I jump around every few months/weeks. Basically waiting for 4.2 to drop at this point.
AOKP when I feel like tweaks
For performance, eos or rasbean ever since I've learnt to tweaks and theme things myself, I have been not needing the tweaks of ROMs like AOKP
Resbean for now, zip aligned, odexed, tweaked up and super fast

You should change the question as "best rom/kernel combination" since rom's pretty much depend on the kernels to perform well.. Franco R25 is the best so far for my taste and Glazed rom is the pair..

Best kernel for battery life?

Hi all
I'm currently running Cyanogenmod with faux's kernel and getting pretty good results, just wondered what other people are using to get great battery life?
Thanks in advance
Sam
Sent from my Nexus 4 using xda app-developers app
No such thing as a best kernel. Some phones like certain kernels more than others. Experiences vary.
If you're looking for kernel suggestions I'd go with Franco or Trinity by morfic (Google to find his kernel as it isn't on xda).
Sent from my Nexus 4 using xda premium
This is really subjective and is something you would need to test out on your own to get any solid answers since there's so many factors that could affect the outcome.
Thank you but it was just to see what others recommend. I've heard good things about the matrix kernel
Sent from my Nexus 4 using xda app-developers app
Also when using those kernels download the app trickster mod it'll let you customize the kernel settings but don't touch anything you don't understand because you might mess something up. Franco and morfic have paid apps that customize their kernel but trickster is a free alternative until you commit to one kernel

Franco or Matrix...But while using Franco Ive seen a big difference in battery and thats just my experience with it but like the others say just try em out and see wats best for you my friend..

Agreed. Franco really knows what he's doing, no offense to the other developers. Morfic is another good developer.
Wasn't a huge fan of matrix on the Nexus S. Just my personal opinion (don't attack me because I prefer one kernel over another!)

Nothing against math kid but (not saying he does this) but there are some shady developers or Rom cookers who say they added their secret special tweaks to boost speed or performance. I don't believe it because it's placebo. If there's no proof in the source then it doesn't exist.
Franco actually says what he did, and you can see it in the results. Plus he's very adamant about replying to feedback as long as it's not a silly question like "can I under volt using this kernel???" There's a reason why he has 20k thanks
But either way enough of my rant. Hope op finds a kernel he likes. I'd start using the most popular kernel out there and use it for a couple of days. If you aren't satisfied then try another. Satisfied but want to see if you can do better? Go ahead and try. They're all free anyways, the beauty of xda

Franco doesn't support undervolting because,
I answered that the last page. UV comes when I think its a good time for it. I do my own thing, not follow what other people do on their kernels.

I really don't care much about undervolting, I think in the end its more placebo than anything. Sure it might help a little bit, but not as much as users think it does. Aggressive cpu frequency management, core management, now thats where true savings come from in my opinion.

I don't really undervolt my phone and have pretty good battery life as it is. I didn't undervolt on my Galaxy Nexus either because it had something called Smart Reflex undervolted for you when necessary. more info @ http://www.ti.com/dsp/docs/dspcontent.tsp?contentId=52746#a18
---- Franco isn't saying that there won't be UV support but as of right now he's focused on other things and will add it when it becomes more stable. And I agree with him on the second part about there are other parts of the kernel that can be worked on to have better battery life rather than just having people UV as the solution (for now).
Edit: there's a reason why his thread on GN has Views: 4,859,042 http://i128.photobucket.com/albums/p163/gbd270/views_zps2644eff7.jpg
Even there's no UV on his r14, this kernel is very stable and I've a (very) good battery life
I really appreciate all your responses, so what settings do you recommend for best battery life on Franco's kernel?

Out of the box settings work just fine.

If takes a couple of recharges for the kernel to come into effect. Have to give if a few days for your phone to get used to it.

The only real flash and forget kernel is IntersectRaven's. Bare bones and full of awesome. Faster than stock kernel, and better battery life. Also stable as a rock. My last up time was 100+ hours.
