Alright, so I'm coming from cm 6 and I was using snap with it. But what I'm wondering, is what is the best kernel for fresh.
Thanks.

I'm running King's latest...#8 I think. Getting 53fps, 1250 Quadrant score with stock 998mhz speed. Seems good so far.
If you want great battery and dont care about the fps cap, stick with the latest stock kernel thats built right into fresh.
best kernel for lastest fresh?
I am using the kernal that came with the rom and it seems to work just fine. i thought the claims on battery life might be over rated but can say that with moderate use i got 37 hours from 100% to 15%. Might try kings again but not sure if that would hurt that battery life.

I promise you that the claims of improved battery life for the new HTC kernel are not overstated at all. In fact... there are no words to describe how much of an improvement it actually is. The theory follows that the other kernels will be re-optimized based on the new HTC kernel.
As above, stock gets the best battery life. If you need the OC/FPS/etc you can try King's #8 (I had stability issues, personally) or #6 (worked like a charm). Currently I'm using the netarchy 4.1.9.1 beta. Battery life could be better IMO, but feels really snappy. LP looks too good @ >50 FPS for me to stick with stock.

I have been running Fresh 3.2 with the built in kernel, but I've also been using SetCPU with a very low performance, battery friendly profile.
My question is whether I should be using SetCPU at all anymore, since I heard that this new kernel already supports throttling the CPU back when not in demand. I've been excited to test out how it effects my battery myself, but if someone has the answer, it would save me a week.

Even if the stock kernel does scale down the voltage to the CPU, I think you would still need setCPU if you want to OC. However, the stock kernel probably does not support OCing. However, I think setCPU could still be beneficial for keeping the CPU running at minimum when the phone is in sleep mode. Then again, that feature could also be incorporated into the new HTC kernel for all we know.
Like someone else mentioned, Kings BFS #8 gave me stability issues, but #6 works fantastic in terms of performance and stability; not to mention, everything works on my phone as it should. I got 2 generic batteries and a charger from eBay for dirt cheap, so battery life if of little concern to me.
Is there a kernel for fresh 3.2 with cifs support?
So guys, i definitely need a sense rom because of the look ( especially the music player, 3.0 lockscreen like in insertcoin and apps) and the fast writing speed of my sd card...
i tried leedroid, rc hd mix, maybe a froyo rom would be better? Or recoment a different kernel?
currently i use insertcoin ( newest stable release), but the battery is so bad i can hardly get a day out with normal use... wifi gps off brioghtness low...
can u tell me a good rom? would appreciate it
I find al GB ROMS have poor battery life then I changed the kernel to MANU's and it was much much better. Maybe try a different kernel?
can u recommend me a kernel?
Yeah this one is really good for me but is different experience for every user...

Gingerbread-HAVS-AXI-CFS
Thx dude, i'll try this.
But i gotta 2 questions:
Can i return to my standart kernel (insertcoin eg) and how can i do this?
Is this kernel also compatible with insertcoin? (sense- based)
With Gingerbread I think the Reflex S is pretty OK for the battery or else it is possible to undervolt further.
Maybe you just need to calibrate your battery, if you change your ROM a lot. I use BatteryCalibration from Market and it seem to do the job.
Do i have to do a full wipe?
Battery calibration does not work for me D the percentage drop fast to 99% percent again and so on
Yeah, I would do a full wipe. Especially if you are moving between different ROM's.
So far, the AuraxTsense 8.4 (Android 2.2) was my favorite in terms of battery usage - but since moving to 2.3.3 based ROM's, my battery drops faster when using the phone, but lasts longer when in standby.
what would u recomment then? returning to froyo or stay with gingerbread?
Well, if Battery Life is your primary concern, you would probably get the best results with a Froyo ROM, since the kernels are further in development.
However, in terms of features etc. I think the Gingerbread is better. I personally like the Sense 3.0 improvements etc. So I am just crossing my fingers that battery life will gradually improve further
My experience is, that Gingerbread ROMs in general are battery hungry. As for sense ROMs i can say that LeeDroid suits me best regarding battery life. At the moment im on oxygen and get a day out of it with normal use.
Best results with battery life i had with LeeDroid Froyo ROM (v2.4 i think). Smartass governor and screen off - 245mhz max/min sometimes got me 2 days without charging.
Maybe this helps you finding a solution.
By the way, you can also improve your battery life by turning off the various Auto Sync features, for example Sense Sync, Facebook, Weather etc...
So i've flashed reflex s now, hoping the battery will do better tahn insertcoin.
If not, i will probably change to leedroid froyo- are there any important disadvantages for froyo roms? like speed or something?
i've tried many sense roms and never got a good battery life
now using MIUI rom .. its GUI is close to sense and good battery life
24h and i still have 40% off battery on InsertCoin 1.0.8 CM7,wifi is always on,data is enable,set brightness to auto. Try charge your desire to 100% turn it off,connect charger again and wait till green led is up,than turn on your phone to fastboot menu (power and volume down) and clean battery stats,reeboot.Also You can use battery calibration app from market

thx c: which rom do ya use?
At first, the recommended manu kernel won't be working with sense roms, because it's an aosp kernel (so made for aosp roms).
Second, using setcpu and setting a screen off profile for it really improves standby battery power. I set it mine to:
128 - 442 mhz ondemand governor
Third, the display is the biggest and fastest battery drainer, no matter which rom you are using.

If you use smartass governor, you do not have to set an extra profile for screen off. This governor automatically uses the min cpu frequency when the screen is off.
smartass governor – is based on the concept of the interactive governor.
I have always agreed that in theory the way interactive works – by taking over the idle loop – is very attractive. I have never managed to tweak it so it would behave decently in real life. Smartass is a complete rewrite of the code plus more. I think its a success. Performance is on par with the “old” minmax and I think smartass is a bit more responsive. Battery life is hard to quantify precisely but it does spend much more time at the lower frequencies.
Smartass will also cap the max frequency when sleeping to 352Mhz (or if your min frequency is higher than 352 – why?! – it will cap it to your min frequency). Lets take for example the 528/176 kernel, it will sleep at 352/176. No need for sleep profiles any more!

I am having the same problem with GB roms no matter how many times you calibrate the battery there is no improvement .
Which rom is the best [for battery life] between these one??
- cyanogenmod
- miui
- stock ics
All with the ultima kernel from riyal.

For me its KA21 with Arcknight 3.3 Stock Kernel.
Really smooth, better battery than i experienced stockwise...
try ICS_anzu_KTG tuned_V1.41: governor interactiv
actually battery drain more depends on the kernels..for best battery life stock kernel is the best
Guys note that lad has Pro not Arc. Stock is usually the worst, or better - default gauge for custom ROMs. I've been watching cyanogenmod discussion for a while, usually users feedback on battery life varied from version to version; for tweaked versions can be said that battery life is the same as in stock while the performance is 20% better. I don't know about MIUI.
(Out of your question, the best for battery life are Ultima ROM and Buttermilk ROM which are optimized for battery life and battery life is notably better there; with Buttermilk and low usage you can do as much as 4 days without charging - worth for outdoor trips. Ultima ROM when idle eats like 0,6% per hour.)
Stock rom with stock kernal had the best battery life... but also lags the most.
I recomend arconium ICS with stock kernal for a balaced experiance...!!!

Well if you game a lot compared to someone who doesn't then obviously ones battery will last longer than the other, so there's a few factors that can be taken into account in regards to battery life.

well my method of testing battery drain(i guess everybody tests the same way) is only on standby..how much time does it take to move 1% down when the phone is not touched for an hr or 2...in exceptional cases battery will drain fast while using 3G in one kernel but lil slow on other kernel..
again my point is kernel is more responsible for battery life of the phone rather than a ROM..

Then you need to take syncing into account, if yours is on and mine is off on the same kernel then yours may drian a bit quicker than mine, which goes back to my point of how a user uses their Phone. I don't think it's a black and white issue.

yea dude.. i get it..my point was simple..people were talking about best roms for battery life.. i just said kernel plays an important role in deciding that..that was my only point..i wasnt arguing with anyone..and testing of battery drain at standby means with data off,bluetooth off, gps off..hence syncing of account wont come into picture
I'm not arguing, just trying to make a point also.

Yes I know and sorry, the last two ROMs I was refering to are GB. However, Riyal is working on Ultima ICS ROM and it already exists in alpha version! See this post with download link Hopefully the ROM will have similar advantages as has GB Ultima ROM over GB stock ROM, which means better battery life, better wi-fi reception, improved camera and so on.

I did that when I had iPhone 4.
im using cm7.2 latest release alvays, i also have an app set cpu and i set my governor to scary, min freq 145 mhz, and max 1024, and im using profiles for apps that im using most of time (underclock cpu while using that apps)
with that i have at least 40% better battery life
and, yes, u can downgrade using flashtool

So far Arcknight kernel has quite the reputation for good battery life. IMO, for roms i find CM9 from FreeXperia project quite awesome but then there's an issue with the battery stats and brightness for now so wait for the next release i guess. for GB try arconium 8.2. still mostly its based on kernel and also the governor.

Hey friend, how do you do that? I dont ahve that option.
I remember i had on my other phone.
Im running the newest version. Should I change my device??
What option are you referring to?
So just wondering what kind of battery life people are getting with stock and aosp ROMs (screen on time). Provide rom name kernel and screenshots if you can.
I'm currently running 10-11 Blisspop
Nebula 10.2.2 experimental
My battery life is about less than 2 hours but using smartmax governer I get consistent performance.

This kernel lets me use my phone all day without the battery dying.
I see these terms a lot when kernels are being discussed to save battery life, can these two be used together? What are the differences? Thanks in advance for any information.

You really can't compare these to but.
AKT basically is changing kernel tunables in such matter that it saves battery or increases peformance depending on which the profile is ment for.. The problem is that everyone has a different usage pattern and everyone's definition of smooth and battery is different... For some Project Zhana can be really efficient and smooth while for me it is efficient/battery friendly but not as smooth.
EAS basically replaces the whole HMP part which almost every device runs now (HMP). EAS is quite new and quite experimental but really stable, you really won't notice it is experimental. EAS is a bit hard to explain for me. But if you are looking for a good user experience and the best battery life with it I would suggest you trying VertexOS.
Now correct me if I'm wrong I'm not a ****ing genius at this!

Awesome! Thank you very much for the info, I understand it much better now
In my experience, I get better battery life a balanced profile on AKT (fusion balanced) on OOS. But performance is amazing on Vertex! And battery life isn't terrible, although not as good as on OOS, and it is still very usable.

Thanks for the insight! I currently have the official Resurrection Remix ROM for my 3T with the latest EX kernel. Battery has been inconsistent for me even with the Wakelocks blocked and a mainly black theme, but I think it has to do with the weaker signal as opposed to OOS. I assume there is a way to apply these AKT profiles in the EX kernel app and have them apply after every reboot? I would prefer to stay with Ressurection over Vertex because it already has almost every feature available, and it would be much more convenient than flashing a different ROM each time for a new feature I wanted lol (since there is no Xposed for nougat)

See the link posted by @juliusedward.
ELI5: Basically, EAS and HMP are way to manage tasks in a multi-core processor. HMP requires a lot a guess work and experience to get it right. EAS is, Well, smart! It gets cpu utilization and load information using WALT/PELT (it's a new topic entirely. Think of them like a function, which they honestly are.) and decides which core is perfectly suited for the current given task and at what frequency. So, it is in it's nature to be more efficient and more battery friendly. Although, through lots of tweaking and optimization in HMP kernels it's not that bad either.
I run VertexOS.
EAS seems offer better battery life, same smoothness, and less warm !

Try Blu spark kernel. It's my favorite kernel in terms of performance and battery life. I can get 6-7hrs screen on time consistently over 24 hours on LTE and wifi. Performance is butter smooth. And when I mean butter smooth, I mean no frame drops, no microstutters, pure 60fps smoothness. Something not a single AKT profile can provide without destroying the battery life so I wouldn't recommend them, and yes I've tried every single profile. FlashKernel is also a really nice kernel but you need to tweak the stock governor settings to get nice performance.
Haven't tried EAS, but supposedly it does its job well, very well so you can also try that out. Try vertex it has been getting high praises.
@slamdunksaliby
Please check this post here
I think it is safe to presume that it answers your question to a great considerable extent.
Hope it helps.

P.S. AKT profiles cannot be applied on EAS, not yet.

Dont blame the kernel if you have standby drain.
I also use bluspark with freedomos ce and i nearly have zero battery drain over night.
If you have too much standby drain its some third party apps, services or something that keeps your phone awake.
