I have to say I have tried EVERY ROM on the SGH-T989 and can say none are as stable and have the battery life to match the stock ROM.
I tried Darkside today. It is a clean ROM. Close to stock. I had two complete lockups on the phone that required battery removal in about a 6 hour period. I am not overclocking at all. The ROM has an underclock by default.
I just think it's time to give Samsung and the programmers there a thumbs up for doing such a great job on this phone.
It would be nice if they could release more of the header and source so the developers here could have a better chance of getting a stable ROM built...but until that happens I will just stay with a rooted and stock ROM.
Peace.
I've had no lockups or any problems in the 150 hour uptime I had with Juggernaut 5.0 with 009m faux's kernel.
Battery life is much better as well. Dropping down to 80% after 1 hour of display time.
Cool story bro

I was on the stock ROM for 6 hours yesterday. Surfing, playing games, wifi enabled. Used a bit over 30% from a full charge.
I jumped right into custom ROM's when I got this phone. After going back to stock is when I realized how much the custom ROM's actually degrade the phone.
I have ran Jugg's 4.x with Faux kernel and Bullet kernels. Bullet was faster by a good bit. Battery sucker from hell though.
Do these phones really need the overclocks and tweaks? After going back to stock my opinion is no.
Peace.
You probably didnt follow the directions when installing any of the roms you tried.
If companies like samsung were as awesome as you say they are, would XDA exist at all in the 1st place?
Enjoy your bloatware.

Keep it civil and to the point. Don't attack my character by implying that I don't know how to follow directions and flash a ROM. I have been a member on XDA since the first year....much longer than you.
I don't have a problem with bloatware. I use a stock ROOTED ROM and remove the bloatware. Very easy to test and then delete bloatware using Titanium Backup.
XDA got it's start back when the CPU and chipsets on phones were very slow. Over time the new phones have become handheld computers. The processing speed is much faster.
In the beginning the OS's were in the infantile stages as well. They have all improved dramatically.
I remember when a flash on something like the HTC Tytan made a huge difference. You were getting the GPS and FM Radio Unlocked. The bloatware was removed in the ROM(Windows based...no ROOT access). It made a huge difference in the performance of the phone and unlocked a lot of features.
This isn't the case with the new phones. There really is nothing being added to the ROM's that can't be added via the market or removed using Titanium Backup.
What I have seen with every ROM is intermittent lockups that require battery removal and excessive battery consumption probably from the aggressive timings that aren't necessary.
Peace.

I look forward to your battery testing!
Please include multiple kernels as you test various ROMs, especially faux and Synergy
And perhaps install Juice Defender as a best case.
Personally I haven't experienced any lockups with the two custom T989 ROMs I've tested, but have benefited from the improved battery life dramatically. I'd still love to see a more controlled experiment, however.

Read it. It is basically a generic thread. No stats or true testing methods just some user comments.
I want to actually test the phone in real life conditions. Watch some vids, talk on the phone, skype/gtalk/YM video call...etc. Actually run consecutive tests across the best ROMS and stock and see how they match up.
Benchmarking is a bit ridiculous....in several aspects.
If a game runs 30 fps or greater...you won't see the difference.
If a game runs a stable 30 fps versus a ROM that peaks at 50 but valleys at 15....you will definitely see the difference.
If a ROM runs 50 fps versus 30 and both are stable...you won't see the difference. The question then is which one uses less battery. The obvious answer is the one running 30fps. Less frames means less redraws and less CPU and GPU.
I just want to once an for all be able to definitively say what each ROM is really doing to the phone with graphs.
Not hard to do. Just takes a real world test model and some time. I think I can test one ROM a day. I will test the most popular ROM's....Juggs, Beast, Darkside, Bombardier, Gingersnap, etc... I have tested them all. I know which ones are legit and which ones aren't.

Nothing has performed better than stock 2.3.6, rooted and debloated.

I run Juggernaut 5, ADW launcher, AOSP ICS themed, with Darkside's latest kernel (extracted it from Darkside ROM pakage), and I've had amazing battery life, OC'd to 1.83ghz with ondemand governor.
And IMO Touchwiz is ugly, samsung tries too hard to make all their stuff look like the iPhone. They do a crappy job of it and it ends up being a dissapointment.
I think any small degradation of battery life is worth the noticable boost in snappiness and cosmetics of the phone. I personally couldn't stand the stock phone, as soon as I could I flashed something different.

Strictly aesthetics can be achieved through the use of different launchers/lockscreens. The point of ROMs/Kernels need to be more than aesthetics. Hence, "some" of the ROMs offered [strictly speaking] are a pretty big disappointment because they're nothing more than themed stuff baked in and offer no real functionality.
I'm REALLY interested in a controlled experiment of battery claims of different ROMs/kernels. Preferably all at stock speeds.

Sorry but there is absolutely NO proof in these pictures.
I can see that your phone was on battery for a bit over 1 day.
I can also see that 45% of your phones battery usage was the display...and that the display was on for a bit over 7 hours.
What I don't know is what was your screen brightness set at?
Does the display percentage represent JUST the LED power for the screen or does it also include the GPU/CPU driving the display?
Where are the numbers for the stock ROM?
Those numbers mean nothing when you don't have a standardized test bed and procedure.

You can use a home launcher on the stock debloated ROM and get the same results with more stability and better battery life.

Actually, unless that test was completely skewed (e.g. screen on displaying black screen), 7 hours of screen on time + 20 odd hours of standby time with use of radios/connectivity is very very impressive.

When you can refer us to pictures of a base ROM with the same parameters and settings for comparison then I might say it is impressive. But with no base ROM data it is purely speculation.

Anyways now thats oout of the way
How much time did you spend between stock firmwares and custom firmwares?
Did you fully wipe the device before flashing and after
Did you do dirty nanoid restores?
A little more info woud be helpfull
at the end of the day if you enjoy stock more great for you.... Use it n move on...
Still missing the point of this thread on a dev website unless you like being trolled.

CM6 is definitely great, I think without question it is a vast improvement.
The only issue I have is my battery life is ABSOLUTELY HORRIBLE. Could be the worst battery life I've had with any phone. But maybe that's just the EVO, with it's big screen and speedy processor. I underclock to 384 mhz sometimes but then the thing slows down and even freezes. I have 3 different batteries and they all perform about the same (not good.) Before I had a partial wake issue but that's gone, and battery life still stinks. I've also tried calibrating but nothing really seems to make it better.
I hear the snap thing is good for battery life but I everytime I open that thread I get a headache. I love this phone and am obsessed wtih it but that thread is a bit much even for me!
Can anyone give me a quick and dirty explaination of what snap is / how to use snap? Which kernel to flash? Some day I hope to digest that mammoth of a thread, but right now I'm too busy reading texts for college and Just want better battery life.
Thanks!
Download app System Panel. Will help show you what is eating up your battery/resources.
Then, download app Juice Defender. Worth it to get the paid version. Its like 3 bucks IIRC. This will help you get more battery life out of your phone.

Yeah, I tried System Panel but the things eating my battery were mostly system things, like Browser. I guess I could give it another go.
Why are Juice Defender reviews so bad? I've considered it before also, maybe will try playing with it again
snap 8.2 is the current release. you can try any of the kernels, but i would avoid the 7.0/7.1 SD Card implementations since that technology has been put on the back burner for a bit.
Snap allows you to you Overclock and Undervolt (aka: UV).
Overclocking of course is for speed and Undervolting may save battery.
all EVOs are not created equal. some like undervolting some do not. so snap is available in multiple flavors. each with a different UV floor. the lower the floor the more potential battery saving..but also the more chance for a random reboot or wifi/gps acting funny. remember UV retards the amount of power so things can act goofy. the different UV floors are 800mv - 925mv. for example...i use the 8.2_900 because it works well with my EVO. the 8.2_800 booted great but after a while started rebooting itself. 8.2_850 just hung at bootup. the 8.1 kernels didn't work for me at all. 7.3b1 was great.
HAVs is adaptive..so don't get stressed if your device fails to boot properly the first time. wipe the cache/dalvik and try again.
so download a few of the 8.2 kernels.
make your nandroid
begin trial and error (I'd suggest starting at 800, 850 then 900 to get a feel)
don't be afraid to wipe the Cache and Dalvik multiple times.
don't worry about the whole thread. just grab the last few pages and read the OP. then feel free to ask.
i also recommend setCPU. you can find some threads for SetCPU configurations to help. BUT....make sure SetCPU is disabled when flashing the new kernel. once you get a working kernel you can enable SetCPU...but during testing phase it will give you gray hair.
jmxp69 said:
Just a few quick thoughts on voltages/freqs after seeing a handful of discussion in the thread:
1) Every 8.2 kernel has voltages lower than stock. The default stock voltage @ 245 is something around 1050.
2) No real effort is made to UV at the top end. It's a little lower, but the objective at the highest CPU frequency is not to UV. Most of the benefit of UV comes at the low end of the scale when your phone is idle (most of the time). Less voltage = less draw.
3) nHAVS scales voltage at each step. There is a min.max voltage at every cpu frequency. This range is fairly small--50-75mv, but it enables HAVS to decide based on feedback from the CPU which one to apply. And the max at each step is lower than stock. So no matter how you slice it, even if you're running 925, you are undervolted. This becomes a question of how undervolted.
4) OC is not about undervolting, it's about overclocking. The differences is voltage vs. frequency. OC means we're increasing the CPU frequency beyond stock which is 998mhz in the case of Evo. If you move your SetCPU slider beyond 998mhz, you're overclocking.
The objective of overclocking is speed. The objective of undervolting is battery savings. Snap gives you both. We overclock when we increase the fequency with SetCPU. We undervolt automatically via nHAVS. As of this writing, UV is handled in the kernel, it happens most at the bottom end of the frequency scale.
I hope this helps clear up some of the questions. Great conversation by the way.

GREAT EXPLANATION Dragin!!!
and also, to the OP.... dont forget, if you do go with setcpu, do NOT 'set on boot' mmmmkay??? lol
Thank you Dragin!!!
That helps a lot! So once you have Snap setup at what you feel is "good" does your phone seem to perform as well as before you had it undervolted? Man, sounds like a pretty involved process - maybe I better wait until I can really sit down and play with it.

Do you mean for the first flash? Or every time you boot your phone?
If not set on boot, it means you have to start SetCPU manually after each boot. Doesn't seem right

Regarding Juice:
I didn't really read too much into the reviews for this particular app. It works. I was having battery issues. Downloaded Juice, got the settings somewhat right to my liking and so far no complaints. Unplugged my phone from charger this morning at roughly 9am, been using it moderately all day, and as of right now at 12:50am, I am at 29%.
Bad reviews or not, I can attest to it working and making a difference in battery life.

Correct.
You can set conditions to do certain things. Such as disable data/3g/wifi while screen is off. Also if you need data synced you can set a condition to enable data wifi or 3g for X minutes every X minutes/hours.
I am not affiliated with the dev in anyway but it def made a difference and was worth the price for it.

I absolutely adore CM6, but I'm really starting to think that it is not battery friendly. Last night my battery went from full to 25% in 8 hours. I had nothing running, my partial wake was fine, and Android system took up 60%+. I really don't feel like doing another wipe, but it looks like I may have to. Just want it to work right at this point.
Again, I truly love CM6, the open source concept, the transparency, the whole clean idea of it, but there is something seriously wrong with the battery life (at least in every install I have tried)

i agree with you. but i also feel that CM6 is on par with the Official HTC/Sprint ROM when it comes to battery life expectancy. however, after i put on the snap kernel and copied someones setcpu config....i got 26+hrs of 'use it as i wish' time + still had about an hour of in-pocket time left. i was hooked. i bet you an imaginary dollar the same will happen for you.
as for finding your EVOs kernel made in heaven...
it's not too bad so long as you have some time. but if you are time strapped, need your phone in 20min and don't read the OP... you will curse and swear. expect to get hung up at the HTC splashscreen a few times and it will bootloop on you before your done. <I'd suggest just leaving your battery cover off until you are done muckn about for that session>
klick may be easier for the some end users because of fewer selections. I've never used his kernels. if i try them, i'll prolly wait till he's put out a few AOSP versions...to work out any bugs.
oh yeah...one odd thing, it seems that sometimes folks flash a incompatible kernel it gets 'stuck'. after that 'bad flash' they are unable to flash any kernel until after they have nandroided back and rebooted...then they can flash again. i had this happen twice....i was unable to get a known good kernel to load until after i restored from backup. /shrug
oh....try this. download the snap7.5_925 kernel. if it runs smooth. call it a day and you should be pretty happy with that until the new versions come out. yeah, if you got one of the _800 kernels running you may pull an extra 30-45min of time...but that requires a level of geekdom that not everyone has.

Yeah dragin, don't hog those sweet settings! I'm enjoying Snap 7.6 and it seems to be helping out my battery life a bit, but I'd love to see your SetCPU details.
I've found that the issue for me is bluetooth. If I have it on constantly my battery will drain 10-15% per hour. With bluetooth off it's only draining 1%-2% per hour.
Seems like the bluetooth needs work on CM6 in order to have the efficiency that the other ROMs i've tried (Fresh and EViO) have. Nonetheless, I'm sticking with CM6 and just use the bluetooth when necessary.
I have the same issue with bluetooth on CM 6.0.0. I am running the stock kernel that comes with cyanogenmod, so this is definitely not a snap issue. There was a bug submitted about a month ago:
code.google.com/p/cyanogenmod/issues/detail?id=2136
I *really* hope this can get fixed for the 6.1 release, but it is currently listed with a low priority. I really love CM6, but basically making bluetooth unusable for more than a few hours really makes me struggle with the using this rom.
Why not the 7.6 with turbo...just wonderin
Can anyone tell me which ROM (STABLE) provides the best battery life on HTC EVO???
Thanks!
I have been through just about all on this site and Fresh's newest seems to work best for me. With moderate daily usage I can go without charging for about 22-24 hours. Of course all I need to go is 12-14 b/c I charge every night anyway, but I did leave off charger one day just to see how far I could go. I'm giving Calk's latest a try right now to see how it goes. Just be sure to give whatever ROM you try a couple charges before making a final decision, as it usually takes this amount to get an accurate read on true battery life.
how many of these post are we going to need lol

I know that the latest kernels off the latest build have been killing my battery, it's horrible for my EVO.
But you really have to try different rom/kernel/PRI/radio combinations to find the best battery life for your Evo. I wish there was a preset rating system for each rom though, just to see how things work for everyone else(i.e. battery life, quadrant scores, force close problems, etc.)...but there really are a lot of variables, so I don't think that may ever happen.
Yeah I agree there isn't a clear cut winner. Everyone uses their phone different so it will differ for everyone.
Totally agree to give it a few full charges... I suggest when you get a new rom and/or kernel installed to reset the battery stats (can be done in recovery) then use it till it dies then charge to full before turning it back on.
Personally, I've been using Fresh 3.3 w/ the Kings #6 kernel and not only has the phone been screamin' fast the battery has been good. I'm only on my 2nd charge up though so I still have one or two to go before everything smooths out.

I have been through just about all on this site and Fresh's newest seems to work best for me. With moderate daily usage I can go without charging for about 22-24 hours. Of course all I need to go is 12-14 b/c I charge every night anyway, but I did leave off charger one day just to see how far I could go. I'm giving Calk's latest a try right now to see how it goes. Just be sure to give whatever ROM you try a couple charges before making a final decision, as it usually takes this amount to get an accurate read on true battery life.

As posted here, the tests showed that CM w/ Snap 7.5 probably has the best battery life - and it seems by a lot.

I'm using the latest Fresh and I just plugged my phone in at 15% battery after 37 hours. I'm pretty happy with that.
Fresh Rom always gave me good battery.. I'm just using the rooted stock OTA and am getting great battery life.

I think it would be a great idea for this kind of stuff to happen. Some aggregated source where everyone can submit their information using various roms, kernels, etc. Whether it be information regarding Quadrant scores, linpacks or battery life. On computer hardware forums they generally have a section dedicated to OCing records with charts listing someones entire setup while attaining the clock speeds. I don't see why a similar implementation can not be done here.

i use Fresh's Rom made my battery life live avg abt 15 hours
Over 40 kernels were tested and benchmarked in 7 different ways, and the results are posted here.
Should tell you everything you want to know, without bringing roms into the picture (since battery life is most affected by the kernel used, not the rom)
edit - looks like I'm a bit late withthat link - I see the thread for that site was already posted above. It's a great resource.
Fresh 3.2, hands down best battery life for me. 3.3 was pretty bad, as was myn's release....which sucks, because myn's rom is otherwise awesome.
I am using Fresh 3.3.0.1 with a baked kernel that is able to over clock. I then have SetCPU installed with profiles for different states of the phone. If my screen is off I have the cpu set to a max of 500MHz to save battery if there are any processes running in the background. I then have my cpu set to 1119MHz when the phone is plugged in or at 100% with the screen on just because I like a snappy phone. Then when the battery drops below 50% I have it return to stock speeds.
I use my phone heavily for things like subsonic, QIK, FB, Calendar, wireless tether, and of course since unlimited data, calling to any cell, and texting I am on it a lot keeping in touch with friends. I also use the sprint nav at least twice a week.
Results will vary from user to user but so far the phone has been on 7 hours and after some moderate use it's only down to around 75% on the battery.
Again this is how I MYSELF use my phone with this rom and kernel this may not be how you use your phone and you may see different results.
What I have done is searched roms and installed them in total I have used 4 different roms. Baked, Cyanogen, Fresh, and Virus. After installing each rom and setting up my phone I made a nand backup of each so I can flash between them as needed to test. I have found out of all of these roms Fresh 3.3.0.1 with a kernel from the baked roms has worked the best for MY daily use.
With all these tweaks, ROMS, and kernels out there to completely customize your Evo or whatever phone you have. My question is, how to make sure to you don't over do it.
I know that I will look at signatures and see what posters have done to their evos...and try some of those things myself. You can see my signature to see what I've done too.
I am a noob, but I have almost graduated to the next level (whatever that may be). There might be several people like myself who sees all these tweaks and tweaks out themselves in excitement over what you can do to your new toy.
I get the feeling that some tweaks (kernels, CPU governors, ROMS) can often have functions that can overlap and actually worsen performance rather then improve.
As a request to all those who have conquered the realm of the Evo and aid us lowly lifeforms in modding our phones, can you help us figure out what is just right, not enough, or too much? Besides, too much of a good thing can be bad...
We can start off with my Evo. Been using Linpack as a reference for performance, and have averaged 36.5 MFLOPS on single thread. How does this stack up?
Interesting, and i am by no means an expert, but here some things I have found out.
Don't use Collins ph battery tweak and Setcpu together. Your CPU will peg and kill your battery life.
Setcpu with a Screenoff profile is unnecessary if you have the kernel governor set to smartass. Smartass sets the cpu to 384 with the screenoff anyway.
Don't let your daughter take your EVO in the tub. That limits performance as well.
Add in that benchmark apps, like Linpack, are worthless.
You couldn't hit "too much". Believe me, there are people who flash things daily. Some several times a day. And think about how many mod flashes a dev does to his phone?
I meant running at once...

Too many things running at once. I figure these phones can handle a lot given the roms people float between...
And you have to remember that all phones are different and that just because I can do something that works great on my phone doesn't mean it will do anything for yours. Or make it worse... Just sayin'

This question is also hard to answer because peoples taste varies so much.
A good example is myself, I like Sense, but I could care less if it is version 1, 2, or 3, I just want it to work good with no problems. I have never seen a theme that I liked better than stock with just a nice photo as a background. In fact, I could really care less what it looks like as long as everything works well when I want to use it. On the other hand, I have almost no use for any of the bloat apps that came with the phone. I remove almost all of them, Including Facebook, the stock browser, the calender and all Sprint specific apps. But I do have a lot of apps on my phone, about 141 user apps, last time I checked for a total of 264 total apps, including the system apps I have left.
I run Fresh 4.2 rom, that I have modified by removing the aforementioned Sprint bloat and built in apps that I don't want or need. I like Flipz rom's the best because they are stable, reliable, and not updated every day, because no update is needed. Plus he removes the CIQ, which runs all the time in the background. I run a kernel that gives me the best performance and responsiveness, with no-sbc and features like HDMI mirroring and 5-point multi-touch, but other than that pretty much stock (trying out various kernels now so can't say which one I will end up going with). The only other mods I have done is I have changed the splash screen, because the white one would wake up my wife when I would boot my phone in bed at night. I also made a battery indicator mod that reads percentage and is easier to see. And I am running the V6 script to eliminate the Sense reloads when exiting apps.
Works for me, but I am sure a lot of guys/girls wouldn't like it at all. So, in the end, it really doesn't matter what I am running, unless someone else has the same tastes as me. And isn't that really the point?
I think I do a lot for my phone. But not too much. Everything in my sig + setcpu, chainfire 3d, juice defender etc
Deck's + SZ + SuperCharger script + ViperMod script.

How much becomes too much the day you bork your phone when you tweaked something you shouldn't have tweaked, and then turn to the forums for help, only to get an attitude at the people who are trying to help you fix your own f'up. That is when it becomes too much.

A lot of people say AOSP ROMs are good on battery life cuz the sense is gone.
Try out Xplod RLS (one of my favs) test it out see how it goes for you. It's an AOSP btw.
For sense I recommend Tommytomatoes Classic v0.0.0.4 its awesome!
How long does your battery last? Are you running mobile data all day? GPS?
I can get around 20-24 hours put of my battery with real heavy usage. Around 2 days with normal use.

sense-free
I've been experimenting with ROMs and kernels for the last 18 months, always looking for best battery life with regular to heavy use. A good custom kernel will sometimes give you an extra 10-15 %. Using setCPU or another app like systemtuner (my pref) to turn CPU down while screen off can also give you 5-10%. Far and away the best thing for my battery is to use an alternative launcher (ADW for me) and then use Titanium backup pro or systemtuner to freeze sense. you just find the two elements in the process list that start with "HTC sense" and freeze them. Night and day. FYI I run synergy and have always come back to Myn's ROMs cause they are good for battery from the start, but they also take well to pretty much any custom kernel, which isn't true for all ROMs. I like everything to work so I always ditch AOSP ROMs a few days after trying them.

Underclocking your CPU typically causes higher battery drain... unless you're overclocking. As long as nothing is really hammering the CPU in the background (which is the problem, not the CPU speed!), then it's better to let the CPU enter higher power states in order to finish the work quicker and return to low power sleep state. Intel calls this HUGI (Hurry Up and Get Idle). Overclocking can have bad effects with HUGI due to the higher voltage required to run at those frequencies. Lol'd at your AOSP comment though. I suppose some people are okay with subpar android, aka sense .
My Evo can last a week on a single charge. CM7.1, 1850 mAh aftermarket battery (slim, stock battery cover), Tiamat 4.1.0 kernel, aggressive undervolting and monitoring of wakelocks combined with 90% wifi usage (3g is the #1 source of battery drain!).

Underclocking is when you set the speed of the processor to a lower setting than the stock clocks where as undervolting is lowering the voltage needed to run it at a certain speed be it stock underclocked or overclocked. Simplest way I understand it.

Real culprit for batt issues
Has anyone ever bothered to understand that theres a pesty bug no one knew of.. Called CIQ "carrier IQ"
Ya this is one of the main reasons behind bad batt.. Sprint and other carriers allow a company to monitor and chart everything we do and it mirrors off txts and data sent and is designed to pick up on.key words... Basically an Invasive tracking monitor. It's a huge in noticed drain... And its been shown to be removed from system/app in many custom roms. But it never does cause its so strattled throughout the OS.

I dont use my phone a lot and my TWAS is usually 0%. I dont use my phone alot, but usually when 5-6 hrs of no use or very light use it has gone down around 20-30%.

Well, like everyone else said, its depends on what your phones handles. Everyone phones handles a rom differently, well, not that differently, but enough to make big differences.
Like the guy above me, I also use SleeperRom. Its a very stable, battery efficient rom.
here is a list of roms I would try out...

I personally would towards 'which kernel should I use?' You've got to remember that although we all have epics, not every CPU is the same. What I am running it he or she is running may not be what you should be running. If you ever check out an oc/uv thread, you will see that people get different results using different settings, even though we're all on epics. You've got to try a couple different setups (roms AND kernels) to see which runs best for your device. Good luck!
via my EPICally transmogrified EI22: adrenaline injected & Supercharged
I currently use CleanGB which has been pretty great. If you're in an area with iffy service, that'll kill your phones battery pretty quick.
After installing a new rom make sure you charge it to 100%, wipe battery stats and then let it die without charging to get the most out of your battery (and having an accurate battery indicator)
In my opinion the way you configure your phone has by far the biggest effect on battery life, followed closely by the signal strength of the area you are in, with maybe a very small effect caused by the rom/kernel combination. Watch what you have syncing. Facebook and Twitter syncs can kill your battery, as can any other app that's always using data. Also, wifi uses WAY less battery than 3G or 4G. Use it when you can.
I'm on stock EI22 with mkasick's kernel and I usually get a full 16 hours with power to spare.

I agree. I have seen 3 questions over the last 2 days with these dumb questions.
but if I was to give my advice, I would strongly advise trying MarcusantROM, Battery life is pretty amazing, just be sure to flash a different kernel, as 2.0.6 is not even offered for download anymore because of bugs n such.
I would strongly advise the Shadow Kernel, paired up with MarcusantRom. You should see some pretty amazing battery life with that combo.
or try these out...
LegendaryROM
SleeperROM
Come on... "Dumb question"? "Lazy"? Get off your high horse. Certain ROMs give better battery performance than others because of certain tweaks and the OP asked for some general advice. Certain ROMs are certainly worse than others. OP wasn't asking for what would be best for him but what has worked good for others. Why is it so wrong for someone to ask for general advice about a ROM/Kernel combo. Not that hard of a question and not so ambiguous that it deserves a "dumb question" or "stop being lazy" response. If you don't want to help the OP, then simply DON'T RESPOND.
As for the question... I generally use the kernel that is included with the ROMs because normally that is what the developer has tested the most. I think Thunderhawk, Sleeper, and Legendary (in that order) are all good for battery but I haven't used all of the others.

In kind if you don't like the responses don't respond to them. I read for a month all the ROM threads before deciding on one to flash. Go to ANY ROM thread and someone there will claim they got the best battrery life there. It is different for every body and EVERY phone. ALL of the ROMs here have tweaks that work differently for everyone depending on use. Also people are sick of every other thread as "what's the best ROM". You HAVE to try them for yourself. If we are being to real for you then don't read what is written.
I was once where you are now. When I couldn't find a satisfactory answer, I made my own solution. I'll be uploading the latest version of it, version 3.3 today or tomorrow.
Battery Used: Extended Battery 2700 mah
Testing Performed: Idle Only
For those unsure, idle testing is simply when you treat your smartphone more like a phone. This included uses such as, checking the weather, responding to the occasional text, checking the time, etc. The primary goal of idle testing is to understand how long the phone can stay alive when used for texting and phone calls only. This is useful primarily for occasions such as, going on vacation, where you would like your phone to last a week or more in case of emergencies, but you'll be preoccupied and not killing your battery with Angry Birds. It's nice to know that our phone is capable older, simpler cellphones in standby time.
This indicates that my phone could stay on for as long as 10 to 14 days.
Direct arithmetic calculations indicate as much as 5.5 to 8 days on the stock 1500 mah battery.
Obviously, usage varies greatly between people and even between days, so anything other than idle testing is subjective. Testing was not performed on a stock installation, but rather, on my own daily personal fully-decked setup.
On the stock battery, I've played games for a total of more than 3 hours over a 48 hour time period before needing to recharge.
This has held true on my phone, my wife's, her mother's, and more than a thousand other user's phones. Yours may vary. Try them all. I do.
