Alright Nexus S community, First off i will say thank you to all the devs and your hard work... i havnt even begun to use all of your awesome work but there SO MUCH stuff in this forum its nutz!
I have been on an lg p500 for awhile now, running a nice CM7 port. Recently i have been given the opportunity to get a Nexus S for CHEAP. I figured why not!
So i come to you guys after about 2 hours of reading through the various threads on kernels and roms.
I am going to be looking for the combination of a kernel / rom that produces the best battery life, with good performance. It doesnt have to be the best rom in benchmarks. But one thats stable with good battery life... with a SMOOTH UI.
Obviously there is alot of developing right now due to the drop of 4.0.4... im just trying to narrow down which rom i will use and which kernel.
suggestions welcome!
Thanks

Most ROMs that aren't HEAVILY edited don't vary much in battery life. The kernel can change the battery life a little, but it sits heavily on whether or not you are OCing/OVing. An extreme undervolt could also give you a tiny, probably negligible, boost. This is something you can change in each kernel anyway though.
As always, the biggest problem you'll face is something keeping the phone awake through a wakelock, or be woken up constantly, as well as the screen being on. No unnecessary wakelocks while idling, no rogue apps using transferring data for no reason while screen is off and no heavy OC --> great battery life.
Try out a range of ROMs and Kernels which have the features you want, here on the Nexus S forums they're all top notch

thats my problem! SO MANY awesome choices! hmmm which one to start with first.
Pick the ones which have all the features you want first, then move onto the ones which are missing one or two, and so on. TitaniumBackup will be your best friend

yes, all of them
first find a rom you like, then try all the kernels. the kernels can make a difference to the rom. it can make it worse, or much better. really, there are so many differences of opinions to whats good, as many opinions as there are users. but, being in the nexus s community, its really hard to make a wrong choice. there is just that much quality here.
personally, i use unofficial cm9 kangs as my rom with all the trinity kernels. but, i do make it a habit of trying all the kernels(and most the roms) at least once
AOKP and Bigxie ROMs, try these.

Pretty much this. Everyone has their personal favourite which means very little to you. Give all of the ones with features you need a try, and once you're happy with a particular ROM give it a shot with various kernels. Later you can expand your horizons.
I'm pretty sure there was a topic not too long ago about how hard it is to choose ROMs and Kernels because there are just so many of them.

well this is good to hear.
In the lg p500 community we had alot of roms that were almost nearly the same, and a buncha junky ones, with a few good standout roms....
Guess once i get the nexus ill begin a flashin and playing!
seems like the major kenels around here are
Air Kernel
Matrix
SG-NS-ICS
yes?

Hey guys,
So, I was wondering.. I am new to the all android experience, I am learning and I am enjoying tweaking and messing around with my phone.
Problem is that I am really un knowledgeable when it comes to kernels and roms..
I tested at least 5 kernels today and tbh apart from system performance on antutu i'm not seeing much, i'm wondering how people can reach 19 hours on here when no matter which rom or kernel I pick my phone just keeps draining pretty fast when i'm playing games..
I want to learn, to understand more.. but for that, I need help.
I want to know how to select a good rom, a good kernel, what features to look at, how to mess with voltages and etc..
I would love to learn, so someday I can be the one assisting other android users.

Thing is that most people here are already.. " in the zone " when it comes to knowledge, so they speak the language that I don't understand.. it's like chinese when I first look at it.
How does a beginner evolve like that?
Btw: I was wondering maybe I should test kernels and roms for a period of time instead of periods of hours? because I don't see immediate results I just switch a rom or a kernel not really giving it a chance to evolve

All users start from scratch bro, we all live and learn till the day we die
First don't care about bemchmarks. They mean nothing in term of user experience.
Second a kernel must be tried at least during one or two days.
Third there is no best Rom our best kernel. Golden rule. Each person has different needs and tastes.
And be careful when you see amazing battery times. What matters is phone usage. Good phone network ? Wi-Fi? Localisation always on? And so on.
What surprises you when you play your battery drains? Normal.
What makes difference is 'idle' time. Use Greenify, fight backend running apps.
Some people spend days tweaking their phones, and though don't have time to use it...

this is normal... what do you expect when you stress the CPU/GPU?
Thing is, you don't just change kernels and run. Many of the efficiencies you gain with custom kernels comes from the tweaks you make to the system made possible by the kernel. These are where you can get increased performance in many respects. Keep in mind, though, no matter what you do, the processors will still be hungry under load and there is not much to do about screen use except brightness control. (i.e. games will kill your battery faster than just about anything else)

Have you checked into finding out which apps and services may be causing your phone to wake up often, or even not sleep at all? Learn about wakelocks if you haven't already. There are good tools for finding out which ones are affecting your battery life, such as BetterBatteryStats.
Check out this thread: http://forum.xda-developers.com/showthread.php?t=1827676
start off by reading.. read... and read some more:good:
I've rooted one phone in my history of rooting - the mytouch 4g. I found it very unstable during that process thus my hold off of rooting until now.
I have a Nexus 5, thus me creating a thread in this forum. I know many will just tell me to google or whatever but I rather get someone's actual response to my post.
That said, what is the different between a ROM and a Kernal. And how can one tell if one is better than another?
I think I want what everyone wants in their phones - stability and extended battery life.
Thanks again.
a rom is the ui, it gives the user variables to adjust and can add some features. a kernel is the central control of your whole phone. it ties the cpu to the rest of your phone, and to your ui. the kernel is like the brain, where the rom is like the outside/skin of the body.
hiw do you know which is better? only by trying them out. some phones will like certain kernels better than others, and you wont know which until you try.
Hi,
Sorry to give you a link to explain what is a rom and what is a kernel, but anyway: http://forum.xda-developers.com/wiki/index.php?title=ROM-VS-Kernel, for me it's a good start.
About battery life it's not the rom that will give you better or worse battery life (unless a "bug"), at least the kernel can play its role but it's mainly your use and settings, the apps you use...
If you have a bad signal reception or a rogue apps with a ton of wakelocks, whatever the rom or the kernel, it will be always the same thing.

I`am not rooted also atm, the device does everything that i need it to do to be honest. Rooting is handy and usefull if you want to use features or do things that cannot be done with the stock configuration. Read the first 4 threads in the General section well if you want to learn the basics of rooting.

Custom kernels provide improvements, tweaks and more power to the user.
Some provide patches to use certain mods... E.g. Multirom patched kernels
Others allow your phone to be overclocked and undervolted. (Both CPU & GPU)
Some just save more battery than others, some have display tweaks included allowing the user to copy Samsung's saturated screens or even lower saturation.
Remember, not all kernels are compatible with all roms.
Read on the bases of the roms and kernel compatibility!
Happy flashing and good luck!

One thing I forgot to mention are also the sound tweaks!
There are a LOT out there that are really good, although the App Viper4Android will always reign superior!
I do recommend you have a look at some of the kernels.
You can get 150% out of your battery with the right rom/kernel combo and probably more if you sacrifice some performance.
Just saying it's something a lot of people don't experiment with, I personally am a flash-aholic and need to flash new kernels and roms every other day!

not true.
battery life is dependant on how you personally use your phone, how you set it up, what apps you use, and the quality of your phone/data connection. everything else, including kernels, play a very minor role in battery.

Not necessarily, depending on the govenor (that comes with the kernel) your phone can idle better and some kernels have adjustments to the LMK (LowMemoryKiller) which handles background apps differently.
So in my opinion with the same usage and different handling of background apps, including undervolting and a battery saving governor.
You could easily hit 150% of the usual battery life,
Kernels play in that matter a HUGE role.
You could even throw in some display tweaks (in the battery's favour).

first off, your "battery saving" govornor doesnt exist. it would depend on exactly what you are doing with the phone. the governor doesnt save battery, it tells your cpu how to behave with the incoming need. and they dont control how your phone idle. i use ondemand, and i doubt many phones idle better than mine.
undervolting DOES NOT save you battery, it can even use more than if not undervolted. the only benefit you will get from undervolting is a little less heat.
and again, kernels do not play a role in battery. if they did, every single person would be using the same battery saving kernel. but we are not. with every single kernel someone will have great battery, and someome will have terrible battery. that's because how ypu use it and your quality phone/data connection pre-decides what your battery will be like.
what you are believing are rumors. stuff people dont really know much about, but still keep repeating the non truth over and over. in reality, kernels have almost no influence in battery.
and btw, everything you can control with a custom kernel, you can with the stock kernel. and people get just as great battery on stock than on a custom kernel.
and yes, i do know what im talking about, ive been part of trinity kernel for 5 years now. and ive helped thousands with android and android related issues, including battery.

its not you i am aggressive with btw, its that false info that just wont die. i had still many people do, but its not as bad as before. you dont need to wipe anything when flashing kernels. but, many people used to insist that its a must. i spent a lot of time fighting that falsehood, now i dont see it as much. its the same about battery. if there was a "magic" pill, everyone would be using it. but just as many people using any random kernel will get great battery life on a "battery" saving kernel, and just as many people will get bad battery life as well.
please, again, i didnt mean offence. im just trying to pass the truth around, thats all. its just that this kind of thing isnt an opinion, there is a truth and a false here. id never go against any persons opinion if it was just about opinion.
Yeah....at best....just changing from one kernel to another MAY affect your battery about 5 to 10 percent one way or the other. In other words.....the direct affect on battery is minimal.
The biggest myth in the threads are that rom/kernel combos make big differences in battery life.
Simply put, they don't.
And everything @simms22 said. ?
---------- Post added at 07:59 PM ---------- Previous post was at 07:57 PM ----------
And in modern devices anyway....undervolting does nothing but keep heat down a bit.....and under clocking has an extremely minor affect as well.
Don't believe, try it and see. ?
I get the same battery life on any ROM....any kernel.
You can make your own ultra powersaving mode or your own hyper performance mode...
I'm just using custom kernel for gamma control, s2w/s2s (which is very useful for me when reading some articles on Chrome), also for USB OTG mounting. Oh oh, and also for killing time, you know messing up with frequency and stuff lol
Well, personally I never believe about the effect on battery life by using this or that kernel since there are lots of things that can affect your battery life, and for my case data connection is the battery killer :angel:
What are you guys talking about??. No, I'm not a kernel dev BUT I have tried so many ROM's and kernels on different devices for a long time now and by experience I can say that they DO influence battery life. I have seen %~50 increase (compared to stock) and aso have experienced just 4 hours of battery because a buggy kernel patch.
They're not placebo when your device start to last 19 hours instead of just 13 like it did since you bought It.

your cpu is set up differently with the custom kernel. thats why. its not the kernel itself. you can set up your cpu on stock so itll be like the custom kernel. its very easy if you are familiar with a few scripts and the root filesystems. for example, i run trinity kernel. with the way trinity kernel sets up my cpu, i get better than stock kernel in battery. trinity set my cpu to run all four cores always on, no hotplugging. it also disables mpdecision. i can set up the stock kernel that way as well. i can do it using a root file explorer, manually, or i can do it via script. and i do know people that run the stock kernel that just get fabulous battery life.
---------- Post added at 10:21 PM ---------- Previous post was at 09:55 PM ----------
there are things that you can do with kernel control apps as well.
Sometimes when you flash a kernel...and many times we flash a ROM right before.....you are only getting rid of a battery issue you previously had before you flashed. So with the clean start, of course you're battery will be much better (especially if you had an unfixed or unnoticed issue before)....and sorry to put it this way, but don't know how else to put it....but the less knowledgeable people think its the new kernel that's made such a huge. Pretty much all the most experienced people know kernels don't make a very big difference to battery life. You can flash clean stock with stock kernel and see a huge gain too if you had an issue before.
Test it yourselves. Flash your favorite ROM and some kernel one day. Go a few battery cycles without changing much or installing much. Then flash the same ROM and another kernel. Same changes and same few apps. And so on...
Eventually you'll get the point.

It's a good job YOU know what you're talking about, otherwise this thread would have been worthless
The point is you can do some customizations with custom kernels. Gamma control, usb fast charge, etc etc.
But battery life? I never see the difference even with the similar usage that I always do every single day, really, I'm living in Indonesia and the data connection is the battery killer that makes me swearing aaaaall the time lol
I have tried that kernel this kernel (except caf kernel), you name it, but still nothing different, except each of them has their own characteristics.
My own solution? I bought a powerbank, that's my magic pill when my phone is out of battery.
Please, don't think I'm bashing kernel devs out there, they do fantastic job with their creations and I hope they don't stop doing that, I myself using ElementalX, because I need the features that the dev offers to user like me.
Sorry if my English is that bad :/

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.

I did. I wrote it and added it to both evernote and "clipboard admin"

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.

"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.
