Kernel suggestions?

Here is the situation, I appreciate any feedback. I'm running Remptive Revolution with the Distinction 1.49 theme on it, I flashed over to one of ziggy's kernels not too long ago and it seems like it rips my battery up. I usually have it around 1.15 on demand in SetCPU with profiles set to 384max when screen off, and 768 max when below 50% and 691 below 30%. It seems like the original ROM kernel was wicked fast but I didn't get a good chance to test out the battery life. I've tried a few different kernels and I'm considering going back to one of the Hydra kernels, I feel like they haven't done me wrong. I'm just looking for a good solid kernel that will give me solid battery and good performance, I know I won't get the best of both worlds, but I'd prefer good battery life. Also, pro/cons/purpose of wiping battery stats? I can't seem to find any info about it.

I really like chads kernels. His newest one an oc to 1.113 and is faster then any other kernel ive ever used with really good battery life. (ive only tested the battery life at stock speeds.) And the purpose of wiping battery stats is to let your phone recalibrate the battery so basically you can get the best battery life. ( i believe at least)

Installing now. Thanks for the suggestion, I'll have an update later on and we'll see where we stand.
The reason I'm hesitant to use KingKlicks is because of a constant bootloop I ran into. And Ziggy was just cool, got some really good quadrant scores on it, but it just ran through battery like nothing. Anyway, thanks again! I'm excited!

I've been using Heyitslou new kernel and battery life is the best since I've owned this phone. I'm also using his Redemptive Revolution ROM.

If you use aosp roms then I would go with invisiblek #17. It's the best that I've found thus far.

Best kernel i have used by far for cm6

I wiped battery stats a few days ago in recovery, and literally every app on my phone started force closing. I had to restore from a backup, and when I did, every app acted like it was the first time I ever loaded it. Had to set up EVERYTHING again. Do as you will, but the ONLY thing I did to cause that garbage was wipe my battery stats. I'd love better battery life too, but I think the software should be capable of relearning your power cycle of a battery if you replace the battery. Can't stay one way forever.. or at least it shouldn't.

does anyone know where I can download KXK #3 or one of his other kernels? I have tried to find them on this site and the ROM manager. Even google's top results are just sending me to theads about the kernels but none have links to the kernel itself. I am going to try using it to get my battery life extended since I really don't mess with my DINC much besides angry birds (addict for life).
Thanks,
JrdnThms

There is a kernel thread floating around here somewhere it has them. I'm on my phone so I can't link but its called the official kernel thread I believe

CM7 Battery Life?

I just root my phone last night and my phone is running at 33° and my battery is geting handed a new one.
Does anyone know if flashing a new.kernel or any tips to conserve my battery?
Any help would be awesome.

Well a new kernel COULD help your battery life, but you'd have to check the specs of the kernel, as some are for performance, others battery life, and ect. But be sure to see if its compatible, and if you find no data on it always make a backup before testing it!
Edit: In addition to a new kernel, turning off your mobile data [3G] when you're not using is always a big battery saver.

From my personal experience, flashing a different kernel like crack. Lol! but most do indeed improve battery life. I have 2-3 kernels in mind that you could use, how ever i use my wifi tether. So i had to go with a kernel that gives my battery life and doesn't affect my wifi, which the other kernels did effect my wifi.
So if you use your wifi tether, and still want to save on some battery life. Try this kernel.
[Netarchy-toastmod-4.3.2-cfs-sbc-nohavs-suv-universal-singed]
If you don't use wifi tether, then go with these.
[sbc-bcnice-stable-v7]
[sbc-bcnice-stable-v8]
[Reminder Note]
It's really up to you if you want to use these, I'm not telling you to do it. Just offering some ideas to help you brain storm on things.. And yes I have flashed the bottom two kernels on cm7 rom, but my cm7 3g was pretty weak, and i do enjoy 4g at work, so i jumped to a different rom.
Got the links, but haven't posted enough to add links in my post yet.

Just saying, I would recommend staying with the CM7 kernel till a stable release since it's still a beta you never know what will happen!

Ummm....yeah. I flashed kernals to cm7 and lost my camera. Can't get it back either. Been trying everything.

Check spare parts and see if you have any partial wake issues

Awesome guys I will most definitely look into it. Because I love cm7 and do not want to get rid of it.
I should probably get back to work, I'll repost back in a few hours. Thanks again!!

Oh and I do have all of the little things down. I have taskpanel, oc widget at 245-576, disabling data, all of it. It just runs really hot and my phones almost dead lol. So hopefully a kernel fixes it.

CM7 is great for battery overall, and Savaged-Zen kernel makes it even better.
I'm averaging double the battery life from stock Sense.
See my sig for links.

Best rom with battery life

Hey everyone I just rooted my girlfriends phone and I was wondering. What is the best rom to have with great battery life? I tried a team nocturnal rom and cyanogenmod but they're not that good. And with cyanogenmod, I hear the phone vibrate during calls. It's a bit annoying.
Anyone have any suggestions?

This is best suited for the Questions and Answers section. This is Development and I can see how you thought this was the right place but it is not. This is for roms, mod, and developmental threads. Please post in the right section next time.
Now to your question please keep in mind that what works for me might not work for you as every evo is different. The best way to know is for you to try different rom and kernel combinations till you find what you are looking for.
Good luck

miui with tiamat or save zen. I never use 4g so I don't care that it's missing. I like sense a lot but miui looks/feels just as good if not better. it's a seriously great ROM! Fast, stable, easily customizable and themeable. And battery life is the best i've had since running myn 2.2. Try it out.

of course MIUI gets the best battery life.
nothing on it works, so your phone just sits there as a paper weight, and that hardly takes any battery to do.

depends on usage...
I sit most of the day without touching my phone. with synergy rls1 Id go 2-2 and a half days between charges if I was home and almost never touched my phone, but Id get 3-4 hours(if lucky) if I had to use it.
With CyanogenMod 7.1 Im seeing 13hours of life if I dont touch it, but Im getting more like 7 of use
if youd like more help PM me

HERE This has alot of great names behind it, have not came across anything yet, battery is very good though! Kernel is tweaked so you can overclock it if needed.

Thanks. I'll be checking this out in a little while.
Sorry I posted in the wrong section.

Thread moved to Q&A.

Finally someone with a similar experiance to mines. Im also using synergy and if im not using it the battery life is excellent. I have installed juice defender and also freedom 0.9 agreesive kernel. I use battery monitor widget to see what kind of drain im actually having. I check the history and using all of the above and if phone is just sitting on the table my avearge reading is 28mah.
If i start using apps and doing stuff on my phone though im lucky if i get 4 hours of use on it also i dont use 4g at all ever so thats not a factor. I just wish i knew why the drain is so high when using it. Ive also done hte battery recalibration so thats not the problem.

Decks can be pretty good and/or runs overclocked pretty well and i still push about 20 hours out of it.

I've never overclocked a phone though. Don't know how comfortable I'd feel about doing it, especially not knowing how to get the phone back to stock.

I have tried almost every rom for the evo and I look for stability, internal memory, battery life, and speed. For a gingerbread rom, I keep coming back to KingsROM Alliance SENSE 2.1+ 3.0 HybriD 3D " The BREED " with ChopSuey v9.1 kernel for good battery life. That is my daily rom. For Froyo rom, I use Koni ELITE Series III with Netarchy 4.3.2-havs-more-universal and I get amazing battery life.

Best battery rom/kernel combo

Hey had a quick q havent been around the evo threads in ages my gf inhereted my old evo and is currently running miui. Was wondering if theres a kernel to make the battery life inch out a bit more , or if theres a better rom out/kernel for the job.
Sidenote: It currently charges to 100,then once unplugged drops to 89 quickly then seems to inherit normal battery life again any ligt to shed on this or are we an anomoly?
Thanks ahead for the help and time invested!

The 100 to 90 thing is a very known issue. You need to flash an SBC kernel. Follow the instructions in the thread below and I promise you optimal battery life
Having trouble with AOSP? http://forum.xda-developers.com/showthread.php?t=1295702

Also you can try a trend I started, and underclock to 537/245MHz...undervolting works wonders as well.
This epic reply brought to you by none other than my roxx'd out Evo.

Hasn't this topic been touched upon ad nauseum?
Under-clocking/Under-volting works great on any of the Sense Roms.
I am running an over-clocked AOSP ROM (Gingerdeck 1.3 Stable w/ SavagedZEn) and I have great battery life. I make it through the day and then some with moderate to heavy use.

I only underclock and undervolt in my aosp roms, as its all I run. I typically make it 2 anf a half days off the charger.

Gotcha. I only started playing with AOSP on my Evo recently. I did the UC/UV thing on all of the Sense ROMs I was running and would get almost 2 days with light use, a day and a half on moderate to heavy.

Thankyou everyone for the input and links this has definately squared me away, cheers!

[Q][kernal] What's a good one?

I have stock rooted, I love the phone and didn't want to flash a ROM so soon but I was wondering, what's a good kernal thats better than stock, that increases battery while not affecting the speed negatively, I currently get about 10-12hrs on my battery as is
Search doesn't work that well for me on mobile, so sorry if previously asked although I did scan the threads but just wanted to see how you guys are doing with your current kernals

Try tdj's dark side kernel. Very smooth and great battery life. Plus you can overclock and under volt.

i think there's only about 4-5 options out there... but each phone's hardware is different so each kernel will be different.
For example, my phone works really well with faux and darkside, but i get quite a bit of drain from eugene's kernel (yes I do configure my clock speed and voltages) people say synergy has great battery life and is smooth, however, my phone says different. it lagged more than the 3 mentioned and battery life was equivalent. There is also the bullet kernel... i haven't played with that... not sure if im missing any other kernels... but yeah i suggest giving the first three a try first as they are currently being supported.
reminder, you should let your phone go through at least 2 charges before comparing kernel's battery life etc... and with our phone.. thats 2 days lol

Pretty much any of the kernels on the first page will give you better than stock battery life. Faux, synergy and the dark side kernel are the three most popular kernels amongst Devs so that must mean something.

To be honest, i only ran stock for a few hours. Ive been running a custom rom since day 1. But I believe it would be better then stock because TDJ has undervolted the kernel slightly.

I'm using the darkside right now and so far so good
Swyped from my Sgs2 T989

I've tried most of the popular kernels and the best battery life I've observed has been with Synergy... hands down gives me the best standby battery life.
But what I've noticed that gives me even better battery life is just turning off mobile data when I don't need it (in class, during meetings)... which also turns off the background syncing.
But in the end, it's all up to you how crazy you want to get with your battery management.
