was curious if somebody could give me a run down of what the differences between the various king's kernels are, and what my best options would be for extending battery life w/o too much performance loss regarding setting up setcpu.
if anyone w/ extensive experience regarding such matters was feeling inspired to write up a guide, i think that would be totally rad for the community, eheh...

Hey mods, I was thinking of an idea, where on each ROM there is a graph depicting scores of speed, battery life, general usability etc. These scores could be determined from votes by the community. I think it would help the community out and also give the ROM a more pro look.
Wouldn´t it be cool if there´s an app going to be released, some sort of juiceplotter, installed on the clean rom, which then has to be kept running for an hour or something, for battery use checking, so the scores would be objective?
The rest is just a specsheet.
Even subjective assessment of various roms performance and battery life could be useful provided a large enough sample that should eliminate outliers for the most part.
Usability is too subjective. You either like Sense or you don't care for it.
Setcpu, havs, 720p support etc are important to some people and not others.
I world support some spreadsheet that would allow to get a quick overview of a rom, as compared to others, without having to read all the forums. Perhaps, this could be as simple as a table in a sticky post in this forum.

Hello all. I wanted to see if tips could be posted on how to increase scrolling laginess and increase fps in things like video and games. I bought my wife the shift and Ive noticed its alot better at mobile gaiming and video playback/recording.
Ive rooted and installed myns warm two point two along with netarchy-toastmod 4.3.4 cfs havs more nosbc.
Ive overclocked to 1.2ghz using setcpu and left the governor on smartass. (no profiles)
These seem to have made a visual improvement, but I want/need more.
So my questionis are...
Is there specific kernels that will help get the results Im looking for? (Im more insterested in performace, but would like batterly life is possible)
Are there any hidden tips that can be done via command line etc that will change things to allow for a better fps performance?
ANy help, links, etc will be appreciated. Ive been searching for weeks already just to get myself rooted/romed/kerneled.
The Shift has a better processor and a better GPU. I don't think you're going to be able to match it by overclocking. There are ROMs that tend to be a little smoother than others (MikFroyo 4.6 is nice), but there's only so much that can be done with the hardware. The Evo itself is almost a year old, and the QSD8650 SoC it uses has been available since Q4 2008.

As bkrodgers said, the Shift has better hardware than the Evo. My roomate has one, and that thing really is smooth, even on the stock rom. It nailed like 1400 or something like that on quadrant, not even overclocked on a stock rom. The only changes I ever make to my phone that affects the scrolling is the kernel. My phone doesn't like havs, the voltage scaling makes it unstable, and it lags severely, on any havs kernel. I get the smoothest experience out of my device from a kernel that has no havs and isn't undervolted. Of course, you get bettery battery life out of a kernel with havs, if your phone can tolerate it. Every phone acts differently on different kernels, which is why there are so many to choose from. So you can find the one that's 'just right' on your device. It takes a little playing around and kernel swapping to find the right combo. And as far as I know, basically all the kernels that have been available for a good number of months now, have the fps fix already baked in. When the Evo's first came out, FPS was capped at 30fps. Since then, all the custom kernels allow for it to go much higher than that, sometimes up to 60fps. I don't believe there's much more you can do with that.
Also, for what it's worth, you might want to try out an AOSP rom. They have much less crap in them, and they tend to run very very smooth (in my experiences). Not to talk down on any sense rom, as I also love sense, and 99% of the time and more than happy on whatever sense rom I happen to be running at the time. Fortunately, the Evo has quite a few selections on roms and kernels, so there is quite a bit of playing around and tweaking you can do, in search of the perfect setup.
thanks I'll probably try miks rom to see how that goes.
I understand about the hardware and that the shift has a better cpu, but is there anything else other than what I have already done to make everything nice and speedy UI wise? I think the biggest culprit is the app drawer being clunky. (like this on the shift as well) No settings in linux that can help there?
Oh and kernels. Ive tried 2 of netarchy-toastmods kernels and havent really noticed a difference. Both have had havs. Should I stay away from these type of kernels to get better visual performance?
ANy other tips on which kernels youve tried and noticed better ui results?
ah yes the elections are great. lol I guess I'll have to try a non havs kernel to see how they perform along with the senseless roms.
Thanks all

You're welcome. Just bear in mind, that if you do try out an AOSP rom, that they have different kernels to use. You must use a kernel that was made for AOSP on an AOSP rom. So don't go trying a netarchy kernel on an AOSP rom
Also, I didn't have as good a luck with net's 4.3.4 kernel's as I did on the 4.2.2 or 4.3.2. Also the 4.1.9 kernel's worked great for me. For some reason, the newest one's don't give me the best performance.
As far as tweaking things using ADB, I don't think there's anything you can do FPS related. I believe there are ways to adjust the undervolting in a kernel, using adb, and things like that. But as far as I know, the FPS is what it is at this point, although it will vary from kernel to kernel.
Has anyone had good experience with using Pimp My Rom and a custom kernel such as KKO? I've always heard people talk about Pimp My Rom in the comments on so many ROMs and Kernels that I tried it for myself and not sure how the performance will be. I'm more of a battery first kind of person who can bare a little bit of lag. Anyone have some good advice or had really excellent results and care to share their setup? I know kernels and governors vary on device and the user but just would like to see. I apologize if this is already posted but it seems to be a dead topic and dont want to revive a very very old one.
Faux123 recently posted a thread releasing his custom kernel for the N1, but for a not-so mobile/linux savvy person like myself I don't have a great deal of knowledge on kernels, or what it adds/does.
What are the advantages or even disadvantages of using a custom kernel, like Faux? Does it save battery, or does it allow for overclocking? Like, what are the capabilities of using custom kernels over stock?
I'm currently on CM11 nightlies.
Any information is appreciated, and thanks in advance!
First I would read the changelog linked in the thread. Then after reading through, you should Google what each item means if you aren't familiar with it (A lot of them are noted as to what they do).
I would not suggest flashing a custom kernel if you aren't sure about how it can help your phone, and what risks you might be facing.
Always research before flashing something new, especially a kernel. :highfive:

Yeah I wouldn't flash something unless I know what it did. On my previous phone (HTC Sensation) I had a few custom kernels flashed with the ROMs i used but other than that I have no experience with kernels.
I have read the changelog, and I can see what most of the items do, but specifically I have no idea. Reading through there are options to overclock/change voltage and increase or decrease battery life depending on profiles and governors used.
Overall I was wondering if it is worth flashing for a medium user. I'm not a developer, but i'm also not an avid mobile gamer. I mainly use internet, social apps and SMS, but don't like slowing of devices. Would the custom kernel be able to prolong battery life (or give other great advantages) while still maintaining the extremely fast response that N1 has already?

You might get some battery life improvements by changing some voltages to decrease the power used. It shouldn't impact the performance if it's a mild change.
*If a good thread already exists about this, please link it.*
Hey Peeps!
I have probably tried all ROM's (Sense & Stock) on my aging M8, and the only ROM that comes with good battery life is ARHD. But, as we all know, it has its weaknesses.
Waiting for responses from you guys!
We do not compare ROM's that has the greatest etc. The best way to find it out is to try each ROM which fits you.

There is no such thing as a ROM with "best battery life" that applies to everyone, in every situation. There are simply too many variable on how different folks use their phones (what apps, screen on time, etc.) your local reception, whether on LTE or 3g, WiFi, Bluetooth in use, etc. etc. etc.
Folks have very different experiences for each ROM. Seriously, I've seen some ROMs where I can get 2 days of light usage, where others on the same ROM will say battery life sucks and only lasts a few hours.
You need to use trial and error, and use what ROM works best for you. There are no shortcuts to that process.
XDA changed their rules some time ago to allow comparison threads as long as they dont turn into a flame war. Please keep this thread civil and respect everyone opinion.
Thanks

what type of effect does it exist on kernel with battery life?
what are the good & bad things of custom kernel? and also can kernel affect on radio?

I'm not that knowledgeable about kernels, and in particular don't mess much with custom kernels.
But what I would say, is that those questions aren't any more answerable then the previous points about custom ROM vs. battery life. Overclocking and undervolting allowed by custom kernels, as well as the choice of governors (which provide various balances of performance versus power usage) will all have some affect on battery life. But the experience is going to vary greatly from one user to another.
Similar to trying custom ROMs, just make a TWRP backup before flashing anything; try some custom kernels, or tweaking kernel settings; and see if the results are desirable to you.
The only real "bad" thing about custom kernels, is that some settings may result in instability, boot loops or no boot. But as long as you make a TWRP backup (before flashing kernels or changing kernel settings), you can easily recover from any such problems.
You also may or may not get the performance or battery life you are looking for, from custom kernels. Which is the main reason I've not been one to personally mess with custom kernels too much. With what kernel tweaking I did on other devices, I never saw a significant performance difference. And certainly not enough to warrant the hassles of system crashes and no boots I was getting.
But others will swear by custom kernels, different governors, etc. Again, your results can and will vary. So that is why its best to try for yourself; and not take another's advice as gospel.
Viper rom is quite good.
