Need to save battery life, as with Cyanogenmod it was bad. Anyone know of a good kernel that gives good battery life?
http://forum.xda-developers.com/google-nexus-5/help/best-rom-kernel-threads-t2477889
first off, questions go in the q&a section, not general. secondly, best rom/kernel threads are not allowed on xda and will be closed shortly. thirdly, battery life all depends on your personal usage, your personal setup, your apps installed/used, and relies greatly in the quality of your phone/data connection. everything else, including kernel, play a very minor role.
As simms stated above, we do not allow best rom/kernel threads.

Hello World! What's your current ROM and kernel you're running on, and what do you normally get for screen on time? I'd like to get some suggestions.. Would like to get through a whole day comfortably
It doesn't really matter how much screen on time someone else gets, it doesn't mean you'll ever achieve that same amount. Screen uses a pretty constant amount of power per brightness setting, but the other things that use power will take away from that and not all those things are to do with CPU usage, which is the only thing a ROM/Kernel can affect.
On top of which:
"Best" ROM.
There is no such thing as a best ROM. The question itself is ambiguous. "Best" is obviously a subjective term.
What I want from a ROM may well differ from what you want from a ROM, ergo - what is best for me could be worst for you.
If you are asking what the most popular ROMs are, or which ROMs people are using, you can see which threads stay around on the first few pages (and have the most posts) in the Android Development or Original Android Development forums. You can also see what other people are running by reading the What are you running on your Nexus 5 thread.
If you are asking which is the most stable, being a Nexus device - they're all pretty stable.
If you are asking which is best on Battery, ROMs only affect battery if they have a feature that is badly coded. You will likely be able to read about this in the ROM threads. ROMs do not impact battery life. The only impact to battery life are your apps, your settings, how you use the phone and mostly, environmental issues such as Phone Signal.

"Best" Kernel
There is no such thing as the "Best" kernel. What we all want from a kernel is different. Again, many people have the misconception that Kernels affect battery life. Let's get this cleared up. Although Kernel devs will build in optimisations and efficiencies that will improve battery life, these are very, VERY tiny...and if 1 kernel has these optimisations, they likely all have.
People will often say "Kernel x is better than kernel y for battery life". This is actually wrong. Kernels respond to user settings. Setting up the governor to favour either battery life or performance is simple enough to do, you just have to do some learning. The reason people think Kernel x is better than y is because developers set their kernels up with their preferred governor settings. This is what we refer to as out-of-the-box settings. The out-of-the-box settings for kernel x may well produce better battery results than the out-of-the-box settings for kernel y, which favour performance. The fact is, you as the user have the ability to tune kernel x or y to perform the same, be that battery or performance - so start learning how to do this yourselves - that way, you can choose the kernel based on the FEATURES you want, and not the fictional performance benefits of one kernel over another.
Hope this helps

Yup that does help... No such thing as 'best'. I didn't make the best title lol.. Currently happy with SlimLP and Franco, just wondering what you guys were getting . What are you on, as of now in terms of ROM/Kernel?

I hate the "it all depends on your phone, each one is different" bullcrap. That may be true to an extent, but some combos are generally going to be better than others. Besides, most people who ask this question just want to know what people are using and what is working for these people. So now that my rant is over, I'm using BrokenOS with Sensei Kernel R52. I'm getting roughly 4-5 hour SOT with roughly 50-60% brightness and 18 hours off the charger. I'm using the blacked out gapps that are linked with BrokenOS and using the black Swiftkey keyboard theme. All of the black saves battery when the screen is on because those pixels are off when using amoled screens. Don't know if you know that or not, but hey, it's there. Also, I've set the kernel minimum frequency to 223mhz using intelliplug with fsync and mpdecision off using the trickstermod app. I've set the scheduler to fiops and changed the read ahead value to 1024. This has consistently given me these results which I consider to be great! Hope that helps!

That helps greatly! Yes, this question was more of a 'Which ROM/Kernel is the best for you' type of question. And yup, I do know that AMOLEDs give you those pitch black blacks, which is good for battery, since those pixels aren't being used. I myself, am a big flashaholic, tried at least 5-6 Roms and a bunch of kernels.. Best battery life so far for me seems to be Slim + Franco.. Never tried BrokenOS, will flash tonight Thx a lot for your detailed response :good:

Each phone is different but that really has nothing to do with battery life, except that maybe some CPU's can undervolt more. I'm not sure anyone has given this "bullcrap" answer you eluded to.

Check out my rom chroma. Franco kernel is preloaded. Huge update coming very soon.

I've tried most of the roms and kernels and have always gone back to BlissPop and either Lean or Francos. BlissPop for the features and Lean/Franco for the battery life. I would consider myself a moderate to heavy user and get between 4 - 5 hours of sot, but more important to me, I start my day at 5am and shutdown around 10:30 - 11:00 pm and I generally have 35% - 40% or so left. Of course your milage may vary, I also greenify what I can, but I refuse to lose any features i use, why have a fantastic phone and cripple it. I generally don't change any of the kernels, except maybe set it to conservative, I've had issues in the past undervolting, but thats just me. For the slight battery savings I don't find it does that much. Again, my opinion.
Just take a nandroid of where you are and try some combinations. Give it a few days to settle in. Repeat until your happy with the combination.

Will most definitely flash Chroma... Looks like one of the best designed ROMs.. Will flash it either tonight or tomorrow morning... And your name seems familiar from the numerous pages I've went through on Franco's Kernel lol. Thx :laugh:
how many hour is stay on the stock ROM ?
Chroma with FK and vomer are poetry in motion. Use it and prosper.
using the rom that i use, and kernel, and the way i set up my cpu, i see between 5.5 and 7 hours sot. which rom and kernel? try them all out, find your best rom/kernel.

Does Chroma have omniswitch? Cause that's a deal breaker
Just flashed Chroma... This ROM is buttery smooth

I am on Terminus currently with Franco Kernel undervolted all frequencies @-50 which is 100% stable in my case. -75 crashes on games and/or benchmarks. My Snapdragon has a PVS 5 binning.

Hey XDA,
my Z3 broke and my insurance gave me 500€ to get a new phone so i got the Nexus 6 32GB Blue for 490 € at my workplace.
Before my Z3 i had many different Phones like the S5, LG G3, NEXUS 5, HTC ONE m7 and more
Well what mostly use me device for is communication, A LOT (LOT LOT³) OF Fn READING (Manga and Reddit Sync) and hearing my music on the way to school/work/whatever .
I am a experienced user with roms and flashing but with this new device i just want to flash something daily driver friendly but feature heavy rom and a good battery conserving kernel
So far ive looked around for some roms available here and already choosen the
CHROMA Rom because it seems to be popular here (Not sure why ?!) (What is "Layers" ?)
and the Vindicator Kernel because it looks very promising (Not sure if its the case tho) and it has a lot of features (for a kernel..)
So what do you guys use and show me some screens of your themes becuase i like the possibilty to use the cm theme engine
Thanks

For stability.. Chroma/hellscore kernel
Or use the JDX based on latest android M which is pretty stable too but you may encounter few bugs

Wow thats an awesome and big post with a lot of tought from you, thanks
I never asked for a best rom/kernel.. just your recommendation and im sorry that i didnt see the other thread you showed me
Do you have a tutorial for kernel settings ? because i didnt have a nexus for a long time now i never messed with kernel settings that much
And what is your opinion on my choosen rom/kernel ? what are you using and why ?

No worries, but recommendations kind of fall under "best" in a way anyway and it is all subjective.
FWIW, I like to use Slim Alpha and ElementalX kernel.
As for tweaks, it all depends what you want. Performance Versus Battery. Easiest thing to tweak is the governor settings. Some governors will allow you to change the Up Threshold. The % of CPU load before it steps up to a higher frequency. Set the up threshold high, it will stay at a lower frequency for longer, of course that impacts performance.

Well i am thinking to go battery but not 100%. but more like 80%
Problem is i dont know what the apps need to work fluid (or not?)
With recommendation i meant something like this
"AWESOME DUDE, I HAVE A NEXUS 6 WITH ROM X AND KERNEL X AND USE IT FOR DD AND LOTS READING
ITS WORKING LIKE A CHARM NEVER hv HAPPIER BEFORE BECAUSE THIS DOES THAT AND THAT DOES THIS"
sounds stupid, i know but maybe someone else using the N6 is in the same scenario as i am.
Got some good news 3 hrs from now i will hold a fresh Nexus 6 in my handy and now someone is offering me a GS6 32GBlack for exchange xD
GOT IT GOT IT GOT IT earlier but happy about this new awesome toy to play with
Hello everyone.
I am looking for the best fit for me as far as a rom / kernel combo. I have had the phone a week and was on stock for a day. Battery life was decent but i was looking for more longevity out of the device. I then flashed Dirty Unicorns and love the battery life but not all the theming and black. Is there something stock like with very awesome battery life I can try out? I do like the stock look L / M. I like simple and clean looking with no extra apps. What is the best recommendation for me?
Thank you in advance.

There's no best combo either. Get the features you want and learn to tune the kernel to your desires

Hi guys im looking for kernel with the best battery life, which one would you recommend for me? Also how's your battery life on oos 4.5.1?
There we go, another "what's best" thread.
The most accurate answer is you have to test it for yourself. Everyone has different usage patterns.
I won't send my usage screen since I never drain my battery to 0%.
Boeffla, ElementalX, franco, Flash... there are few of them. Just look them up, download, flash and test.

That's what I want to do but maybe someone has tested already ?
In my view,
1) Franco kernel is the best if you use your phone not for the full day because practically I do not see any drain of battery in sleep mode.
2) Blu spark kernel is the best if you want to customize the clock frequency as it is compatible with Kernel adioter app which is free. In Franco as well as in Elemental you have pay for their compatible app.
3) ElementalX kernel is the best, if you use your phone daily, then you can customize the clock frequency and other stuff in aroma installation while flashing.
Now, it is up to you to choose.

There are already so many threads like this. We don't need another. That was why he said "another" best kernel thread.
Expected others to do the testing for you is pointless. There are too many variables regarding how you as an individual use the device. So testing under your particular usage conditions is the only reliable indicator.
