Hi,
This one:
​
EDIT: http://lmgtfy.com/?q=how+to+compile+the+best+kernel+for+battery+life?
:cyclops::fingers-crossed::victory::silly::silly: :silly::laugh::laugh::laugh:
And yes I'm happy with this

Just try them all out. Different people will give you different answers as to which kernel will give you the best battery life. Why? Because battery life is subjective. Everyone do different things with their phones. If you're a heavy gamer, your battery life will not be so great. But if you're a person who only browses the web, read articles, text and make calls. Then you'll have a long battery life.

on stock rom. can change the kernel ?

Not using any kernel will give you the best battery life.

Yea don't use any kernel at all, just the ROM. Heck, just don't use your phone, that'll give you great battery life lol.

Try a kernel.
People have been getting good results with franco, motley, matrix, basically every kernel except for maybe trinity. I would suggest you try franco and motley first.
Flash a custom kernel it contains the msm wake lock fix that Google has not yet implemented in the stock build. I suggest Franco and to download better battery stats to ensure no wake locks and that your phone is deep sleeping

On said Trinity
Well nevermind then. Just install any kernel.
That guy does have perfect signal though. I would just try one and if you dont like what you see try the nextone.

Good battery life kernel?

Currently running the sabre tooth kernel, runs very quick - but device seems to die rather quickly. Any other kernel that people can reccomend for the WiFi nexus7 that offers better battery life with minimal lag? Current ROM is also the sabre tooth latest build.

Try Franco.
http://forum.xda-developers.com/showthread.php?p=29990763
I'm using M-Kernel and I would say that this is a very good kernel in terms of battery life and performance, although this is not geared for performance per se, but this kernel is more of a balance between the two. Other users reportedly are happy with the Omega Kernel, its still relatively new, but the reviews are good. Go try them out.
I like franco and lean kernels. To be honest, I cannot really decide between these two. The best is to try them both. They are very well tuned, so there's absolutely no need to overclock - this is very important to preserve battery.
Anyone able to post a link to the Franco kernel? The one in his thread is not loading the webpage where it is housed.

Thank you! Link is working again, the first one you posted was not loading earlier.

There's also a thread in one of the subforums that lists most of the current kernels and runs each one through the same tests to rank them by speed and battery life.
M and Franco seem to consistently be the top two for battery, but I wonder if that will change if Clemsyn's is ever updated.

I was wondering the same as I used Clemson's before....was beautiful on 4.1.2...then it just gave up on updates once AOSP 4.2 rolled out.

ROM/kernel combo with good battery life

Can someone please recommend a ROM kernel combo for great battery life.
Thank you

Any ROM with Trinity Four kernel will have good battery life.

AOKP steves PUB build , with Faux Kernel and ECO mode turned on
Faux Kernel has a pretty good battery life. Didn't try another Custom ROM though

I used Faux before I switched to Trinity. I thought battery was pretty good on Faux, but people convinced me to try Trinity and it has even better battery life than Faux. Give Trinity a try

No it can't but even with 4 cores on, I still get amazing battery. What kind of battery are you getting on Faux? You have a quad-core monster, why make it dual-core when you can keep it at quad-core but have great battery life?

Yea dont get my wrong, i dont use ECO mode that much, only when i go out and i know im not gonna be near a charger for a day + ... otherwise i get around 5 hours screen on with all my stuff happening and a few games,
i will probably go to trinity one day, im really waiting for him to release that display app that hes teased!
I have only used AOKP with franco kernel and have been getting great battery life. May try Trinity or Faux to see if I notice a difference.

Best rom for battery life ?

Which one is better ?
Nexus 4 cihazımdan Tapatalk 2 ile gönderildi
There is no real answer for this. Everybody has different results. For better battery focus more on the kernel. Try one for a few days, then another and compare performance. Keep going until you find what best fits your needs. Remember there is no overall best, but rather best for you.

Kernel, is more important for battery life, than just the ROM, plus your settings and apps make a huge difference too.

I've tried CM, Minco, Xylon, PA, the best I get is CM with franco kernel of course.

Which CM ? Official Nightly, or something like SlimBEAM ?

Official nightly usually is more cutting edge, but the M builds are more stable and would probably have better battery life.
Third Party Cyanogenmod, like SlimBean will most likely have lower battery life due to adding additional features, but like the other individuals said the kernel is more important than the ROM itself. A ROM can only be as efficient as the kernel itself.

[Q] Recommended Kernel for Nexus 4?

I know with the SGS3 some of the bigger kernels were ktoonsez and lean kernel. What's good for the Nexus 4?

Pa kernel colors are great so as the battery life!

I've been using Matr1x kernel for quite some time now. It's the best I've used. I've tried Faux and Franco and those didn't work too well for me. Try them all out though and see what works best for you.
Sent from my Nexus 7 using xda premium
Franco's latest kernels have been very battery friendly. They're amazing. You do kinda sacrifice (albeit super tiny) performance though.
If you care about performance more, try Motley's. His kernels are reasonably battery friendly, but doesn't sacrifice any performance.
Trinity and Matr1x are my preferred kernels due to their speed and overall stability.
Battery go for Franco.
Hmm. I think I'm gonna try out Franco. I'm on the go a lot and battery life is a bit more important to me than performance. I wish the nexus 4 was more than a 2100 battery...

Yes to be honest Franco's kernel is the only kernel I'm confident with when I go out LOL
must say though the hunt for kernels has been remedied by google, for me at least. their 4.2.2 is insane. im getting 21.800 in antutu without touching the clocking frequencies. im getting 1-2 days of use and still 4-5 hours screen on. its reliable, it wont crash or screw up otherwise and best of all i dont worry about it, at all, its enough for me to settle and think of kernels no more. only thing that really bugged me on this plattform were the colors. but thats solved now. if you wanna try: http://goo.im/devs/paranoidandroid/roms/mako/ start with contrasty and see if you can live with the brightness, that one has probably the nicest colors that can be possible with this panel.
