Best kernel for battery

So since now it's allowed to ask... What are the best kernel/settings for battery life, counting I don't do heavy stuff (I don't care about performance)?

Although its allowed to be asked now, it doesn't mean the answer changes. Your question addresses 2 things.
1) "best"
2) "battery"
Well let me start by saying in regards to ROMs and kernels, there is no "best". Best is subjective. What is best for me is not always best for you. That's why these threads previously were not allowed.
Forgiving the term "best" in the above context, let's look at kernels and battery life. Now here is a shocker - they're all exactly the same!
Battery is determined by how you use your phone. Your settings such as brightness and auto updates etc as well as what network you're on and how strong your signal is.
Kernels do have optimisations that could lead to pretty much unnoticeable improvements in battery life but if they're in one custom kernel, they're in them all.
"But, but how come I get better battery on kernel x than kernel y? Surely kernel x is better for battery?"
No! There is no battery difference between kernel x and kernel y. It may seem like kernel x is better for battery but different developers set different kernels up differently. Dev x maybe set kernel x up for battery and dev y set kernel y for performance. So out of the box, the kernel x seems better. But all YOU have to do is change the kernel governor settings and make kernel y the same as kernel x on battery or make kernel x perform as well as kernel y.
In short, there is no such thing as a kernel that is best for battery. Hopefully you have learned this now. Choose the kernel with the FEATURES you want THEN learn to tune the governor to get what you want out of it.
All the kernels here are good.

as @rootSU said, "best" does not exist. we all use our devices completely differently so best kernel would be best depending on your personal needs and how you use the phone. also, battery life is all about how you petsonally use your phone, how you set it up, what apps you use, and most importantly is the quality of phone/data signal. everything else is very minor in relationship to battery.

These for sure ^^^^
Anyone that says otherwise is simply misinformed. ?

The kernel itself has nothing to do with battery life, it's the CPU and GPU tuning that effect performance/battery life and each kernel is probably tuned a little differently by default. That being said, you can tune any custom kernel any way you want.

People never believe this to be true lol. So hard to explain it sometimes. Maybe this answer needs a sticky thread?

It's mentioned in the battery help thread....just no one believes it. Lol

What is best ROM for performance and decent battery by your own experience?

Title says it all, I'm currently using PA and I'm not satisfied with performance.

none

try a different kernel. performance and battery doesn't come from Roms. performance from kernels, battery from your use. battery life all depends on your personal use, your personal setup, your apps installed, and the quality of your phone/data signal. everything else is minor battery-wise.

well, i personally dont use cm, so cant really recommend a cm kernel. i know cm users could recommend one. i hear elemental has a good cm kernel..

[QUOTE=Isus
I use simple aosp with Franco kernel
Set the hotplug on Franco to 90 and governor to interactive
Now enjoy both performance and battery life

"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
Also, please note that as above, "best" is still subjective. 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

Kernel for stock ROM 5.0

Hey guys.. Returned after a long time on XDA.. Was using unrooted nexus since a year now..
Planning to unlock bootloader and get a custom kernel for my n5 currently on lollipop having LRX210..
Which would be the best kernel for stock ROM..?

I know this.. Got your point, Visiting XDA like after a year almost so forgot how even I used to answer to such stupid questions.. Will go through kernels.. Want kernel just for root and recovery and undervolting..
I would change it to say which is the most stable kernel with the stock ROM?

They're all pretty stable. Personally I prefer to use ElementalX, but really just look for features and try

Which kernel

Hi,
Should I root my nexus 5?
I still have a year warranty so...
Which kernel should I flash then : Franco Kernel, or Code Blue Kernel?
I am running lollipop 5.0.1 stock right now. Screen on 1/4 brightness, no location and WiFi turned off when I don't use it. Know I am getting around 12h battery life with 2-3h screen on time, would one of the kernels help with battery life? And how much? Will it be worth to void my guarantee for it?
Thanks in advance!

Hi!
Thanks for taking your time and your explanation mate, you really helped me out! Think I am gonna see for Franco kernel, cause there are more users and more tweaking options to fit my wills.
Thanks again!

Best Kernel

What do you guys think of the best Kernel for our Oneplus 6?
For me it seems like the Flash Kernel works the best but i would like to hear your opinions
Edit:
I listed my Stuff in an Excel Spreadsheet, currently running Radioactive.

Obviously each kernel is unique in its blood sweat and tears. Just try them all and leave em on for a few weeks. Usually the older toolchains have better battery and more stability in my testing. The benefit of certain kernels are exculsive CPU scaling governors modded by the developer. Currently running pappschlumpf's Smurfkernel with smurfutil battery profile spectrum on havoc nightly. I look for stability though and for stock OOS all kernels run pretty solid. One thing you need to be sure is that the kernel manager is locking frequencies otherwise I find a kernel that allows this. Lately I've had some trouble on blu kernel

Ive tested Stock, Elemental X, Franco and Flash Kernel in Idle Drain per Hour and Antutu Score
and Flash got almost as much as Stock in Antutu while only using 2.9% per hour

100% radioactive kernel
