I realize this device has only been out for a very short time, but are there currently any stable/semi stable kernels that improve battery life? I've looked through a few kernel threads, but many seem to be unstable (which is to be expected) and optimized for overclocking. Are there any kernel developers focusing primarily on battery life?

Stock kernel is fantastic. If you're having issues, we need a BetterBatteryStats log from you.

BBS is not compatible with 4.4 yet. Sven is working on it.
On topic: stock kernel is good. I'm getting excellent battery life, 4+ hours screen on time is no exception. It's a common misconception a custom kernel is a magical battery life extender.

Both faux and franco kernels seems to be maturing fairly well. I can't personally vouch for franco, but I've been stable on every iteration (betas and stable releases) of faux's kernel, with the exception of some aggressive undervolting, which is not a really reflection on the kernel. Battery life has improved, particularly for sleep mode. Can't say the screen on time has improved dramatically, if at all, under these kernels.
FWIW, I have been fortunate enough to have a phone with adequate sound output, so I have not played at all the the sound mods available through faux, only the CPU/GPU/memory settings.

Franco kernel on the N4 gave me 1.5 to 2.5 hrs. extra screenontime compared to stock Thats a fact and no placebo.

I tried all popular kernels on my GNEX. And by trying I don't mean flashing a new one every other day, used them for a couple of weeks at least. None of them produced any noticeable increase in battery life. That's a fact as well. I only used them for their options.
I'm curious what makes people think what the mechanism is behind hours of extra screen on time with a custom kernel (where custom is 95% or more original AOSP code).

Read some Franco N4 pages and you`ll see my statement confirmed. The Gnex (which i only owned for a very brief period) is not the N4.

I've read dozens of people claiming Franco, GlaDOS, Faux, Trinity, etc did wonders for their GNEX battery life. They never did for me, despite I used their recommendations and setup. I've yet to stumble upon actual proof (and I don't mean screen on time screenshots accompanied by opinions of users) a custom kernel actually uses less current than the stock one. If you have some, I'm very curious to read it.

There is a beta version posted on XDA that works with 4.4 http://forum.xda-developers.com/showthread.php?t=1179809
BBS beta has been available in the forum for weeks. It's almost always on the first page, somehow people keep overlooking it.
As far as kernel battery life goes, I think it can matter in certain cases. For instance, I came from the S3, and I don't know about other phones, but the battery life on the CM 3.4 kernel was absolutely terrible (3.0 was fine). Custom kernel was needed not only to tame the battery drain, but to improve stability (fix hotbooting, etc.). Support for that device has been sub par for a long time on the AOSP front. If it weren't for KT747 and leanKernel, CM wouldn't have been usable at all (3.4+). Though, there is still a very valid argument that it wasn't usable anyhow. So custom kernels can make a difference in some cases.
Sleep is an issue with the stock kernel? I get 0.2%-0.4% drain per hour while idling. Zero issues here. If you want proof, I'd be happy to attach a BBS log for you guys to inspect. I don't disable sync or GPS. Never have and never will. You need to be in control of the apps on your phone.
Perhaps I should have clarified: my battery life is actually very good. I don't have any major complaints, and my idle drain is insanely low (the 0.2% - 0.4% figure claimed by Aerowinder isn't too far off). I'm coming from a Note 2 though, so although the battery life is good, I'm always looking for something to make it a bit better . I've been watching Franco and Faux kernels, but they seem hit or miss based on what I'm reading and the personal experience of my friends. I may wait a while longer for a stable release.
Hello. So I am currently running an OPO on 5.1.1 with AK kernel and I get a solid 5:30 SoT with lots of restrictions (CPU frequency). My device is rooted with TWRP installed. I ask, is it worth reverting back to CM11 on 4.4.4? I'm looking for features and battery life mainly. I might change themes and kernels. But only on CyanogenMod ROM. If CM11s is the way to go, may a good kernel be recommended to go with it? Thanks for the help.
Well at this point 11S is pretty outdated, with CM13 already being out. CMOS12 is pretty good but getting a different CM12 or CM13 based ROM is best way to go in my eyes. I have tried going back to KK just to see what it is like and I couldn't use it because I had gotten used to how Lollipop and Marshmallow are. Also I don't think the increase in battery life is worth the loss of features with CM11S.
You should stay on cm12.1 and play with your kernel setting little bit!
I'd say give MahdiROM 2.9 a shot. It's CM11 and gives me great battery life, as well as being packed full of features. Even ran tests with play services forcing my phone to stay awake 100% of the time and can still push 5-7 hours SoT depending on usage. 7+ with that fixed up. ZaneZam's boeffla kernel builds for it work extremely well and I can honestly say I prefer it for CM11 even though I'm an avid AK user.
What about Boeffla Kernel? Is it better than AK?

There is no better or best kernel. There is just a kernel that fits your preferences.
I can only say that at least with my personal usage, the battery life did not change a bit going from kitkat, over lollipop, to marshmallow.
6h SOT is the bare minimum I get on regular usage no matter what. I've seen 8h SOT on K, L and M.
Always CM11/12/12.1/13 with stock kernel and stock settings, no undervolting, underclocking, Greenify or other bull**** apps. Also I don't use apps which are known for drain like facebook.
Seeing threads like this, I often think that users drain the most battery by constantly looking for tweaks and updates to reduce battery consumption.
Alibi screenshots from an early unofficial cm13 build:
There is almost no drain over night, same on data only.

Maybe your device got powerful battery and your app list isn't huge, otherwise most people struggle to get 6 hr sot on L & M. ?

Just wondering what kernels are showing best battery?
ElementalX
Best kernel and ROM plzz tell guys as not happy with stock OOS 5.1.8
Franco Kernel works best for me.
Definetly franco kernel in terms of battery life. But everyone have to decide by themselves which kernel is best.
For every different user, every kernel will yield different results.
All i can say atm is that every kernel out there is amazing, stock is better for some users but has less options.
I recommend you to try it out few kernels out there and see what's better for you, as i said earlier its different for every user...
Usage patterns have a far larger impact on battery life than kernels do. A kernel that gives good battery life to someone who is gaming all day and sees 5+ hours of SOT isn't necessarily going to be be best for someone one doing mainly email and messaging with the phone in deep sleep 90% of the time. From what I've seen here, usage patterns are all over the map, so someone else's recommendation isn't likely to be of much use to you.
Just try them all and see what works best.
Smurf kernel with Helix_Schedutil as governor
Hey everyone. Was wondering what are you using as a rom and kernel?
So far my op6 doesn't do more than 4:30 h of sot, which is kind of disappointing. on my pixel with the same setup and usage, I used to have 6:30-7h a day.
Thanks and feel free to post below, or if you have any battery tricks , let me know please. Tia

I'm currently running xXx no limits with Smurf kernal. Averaging between 6-8 hours sot depending on what apps I use and how long I use them. Even how hot it is outside effects the battery life. Everyone is going to have different results even with the sane Ron/ kernal setup. A lot of variables when it comes to battery life.
I personally use xXx no limits with Franco Kernel. But I agree with the previous comment, everyone will have different experiences with each combo.
I'm personally loving this combo as I've been averaging 7ish hours SOT, plus it's still as smooth snappy and responsive as ever!
Don't think there is such thing as "best", just whatever you prefer. I'm using stock + Flash kernel. Smurf kernel and EX are also really good!
Best thing to do is start flashing and experimenting with some combos and see what you like best.

Default settings for franco kernel, or did you use certain settings ?
Thank you

Depends on the day I'm about to have.
For a standard day, I'll just run it as default settings.
If I needed a bit more then I'd underclock CPU and GPU from the FK app. There is minimal noticeable difference in terms of performance when you underclock it, I just didn't do it daily because I'd consistently go to bed and put my phone on charge with 40%+ battery left at the end of the day, I thought may as well go full power haha.
Hope this helps
There are no "best" roms or kernels. It's largely preference for what you're looking for.
As the title say, which ROM has better battery life among android P custom roms? im asking this because I did install stock android p and I faced huge battery draining on stock + heat. I don't wanna disable adaptive brightness for that either. So im wondering whether the battery life is batter on customs roms. If so please do mention the rom you have
i cant stand adaptive brightness not only does it kill battery, but it scales at the worst times and not in the correct intervals. i believe my preferences and environments change to much for the "machine learning" to do its magic.
ANYWAYS. I believe carbon rom with flash kernel gave me the best battery. i used the unified script with it, and enabled Smart pixels (on with battery saver, 75% move every 10 min) . With that setup i was able to get about 6hr SOT moderate to heavy usage.
Aside from that, any lineage based rom is going to be good on battery. A few people here swear by stock rom with a community provided kernel. Give elementalX a try on stock rom and see if it helps.

So adaptive brightness kills the battery?hmm. For me it is good . Donno about battery because i haven' used my phone disabling it. Anyway carbon rom + flash kernel give you android oreo battery? that's all i wanted.
