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.

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

I've been using the nexus for a while, and although I like the stock rom, is CM11 better? Or any other rom in fact? And I guess when I say better I generally mean performance and possibly battery life? Would a kernal also affect this?
Sorry if I seem naive or anything. Recently switched from an ATT S4 with all its bootloaders and such..
"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.
For tips about improving battery life, please read [Battery Life Help] Troubleshoot battery issues here!
"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
The biggest thing is some of the customizations you can get with something like Xposed. A kernel might change things. You can always make a backup.

You should add the following to the end:
[THREAD CLOSED]
CM and other ROMs that have SuperSU baked into the system (as opposed to have it installed as an app that shows up in the app drawer) can have difficulties with apps that won't work due to being rooted, and often times the apps you can use to temporarily block/hide root access won't work properly with SuperSU baked in. That's the big reason why I stopped using them. It's simpler to just root stock Android and use xposed modules that can replicate 95% of what CM brings to the table.

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.
