Use chop suey. That's a a good kernel. Imo

Just go around and test out a bunch of kernels for yourself. That's really the only way to find the best one that works for you. Reason being that no two phones are exactly alike. So while one kernel may work best for my phone there may be a different kernel that works best for yours. Also, different people have different expectations of their kernels. Yeah we all want better battery life. But our thresholds for tolerance rest at a different level. So in the end the only person who can tell you what kernel is best for your phone is you. Those of us replying to this thread are merely making you aware of kernels to flash and test.
Having said that, I recommend you check out the link I've attached below in order to get some ideas on where to start.

I like the Aggressive Freedom kernel.

I use chop suey 9.2.7 no setcpu or any of that. Just install and let it do its thing. Buy remember it takes a couple of charging cycles for the kernel to settle in. I get like 17 hours off of a charge with pretty heavy use. Also all phones arnt the same so what works on one might not work on another

If my phone seems alright to me, is it worth flashing a new kernel?

I dont have any complaints with my phone. Im running htc kernel #17 and myn's warm2.2
The phone is great to me as it sits, so is there any other features that should sway me to flashing a new kernel?
also whats the difference between HAVs and non-HAVs? Whats sbc? Dont tell me to search because I did and well didnt get much, only on BFS and CFS
Imo, if you like your kernel don't change it. When I find a good kernel I stick with it . Just my 2 cents

Thats kinda what I was thinking.. but I dont know whats out there ya know? Is there really something better out there for battery and speed versus the HTC #17? I seen alot of myn's running the stock kernel. So that could be they are happy with it, or maybe they haven't flashed anything over it yet.
Surely with all the knowledge out here, there has to be a kernel that still utilizes great battery with more speed.
Heat does effect these phones right? Like life span of the CPU, battery etc.

[Q] Best kernel and rom combination for battery life?

So I decided to go back to an Epic instead of an Evo. I had the Epic when it first came out up until around January. Last things I remember from the Epic development scene was Herver and his Baked Snack Roms and Kernels. (what ever happened to him anyways?) I am obviously in no way familiar with the current crop of roms and kernels and would appreciate suggestions on where to start and I'll test combos to see what works best for me. Froyo and Gingerbread based Roms please.
Try out simply asop 4

Good choice. Don't overclock if battery life is a concern. If you want some overclock, go with 1200. I have 2 batteries so I run 1400 max

no 2.4 was the latest. he stopped dev cuz he now had an evo 3d..
I too am looking for the best battery life and I'm having trouble getting it. Currently trying out latest random rom for EC05 and its decent but nothing amazing, I've also loaded the super V6 memory script and the battery just doesn't hold up very well. Where can I get the old baked snack roms?
Sorry to let you guys down, but I can't seem to find the files for baked snack. I'll keep looking though.
i had excellent battery life on the bonsai rom and kernel
Rebirth + Genocide, 38 hrs. moderate use........
Syndicate frozen 1.2 and genocide 2.0 give me the best battery and stability so far, but random rom is a very close second, and then probably viper synergy 5.0. The gb leaks were good with battery too, but I had too many fc issues with them. I would love to try this baked snack I keep reading about though. I've seen a lot of random posts here and there mentioning it, and always boasting about the battery life on it. A pm with any info on its whereabouts would be greatly appreciated. Then again, syndicate 1.3 seems to be just around the corner too, so I'm really interested to see what's in store with that as well.

I am hooked on random rom hawk, battery life is amazing. It usually only drops about 1-2% an hour for me sitting idle. I have heard urban warfare is very good on battery life as well. Gingerbread leak roms are still pretty unstable at this point though. Only try them if you have a good backup procedure down, and are prepared to get hit with force closes and random reboots at any given time. If you need the stability, stick with EC05 roms.
Sent from my SPH-D700 using xda premium
I've tried several roms froyo and gb and the best battery and performance I seen was with randomroms 2.3. Rom but the random reboots kept pissing me off so I wentt to pheonix and its been pretty good I hadbetter battery life with hawk but this is better for now.
I also would like to try backed snack so if anyone has the url t the rom or anything can you please let me know
I found one rom a long time ago butit was 2.1 so I didn't like it I kno there is a froyo one but I can't find it anywhere if anyone has it it would be greatly appreciated if you shared it.

I would recc. simply asop4. an update to the rom is also coming so be prepared for that. then get setcpu and UV the voltages as you wish. I have -25 200-600 and -50 800-1000 and finally -25 >1000.

Best battery saver ROMs

Can anywone tell me a best rom for save battery ?
Now i have Oxygen 2.3.1 Bravo
I would think the Oxygen you're using would be one of the better one's for battery life. Don't go for Sense rom's as they'll drain your battery real quick.
Well anything oxygen based, or the gingervillan roms
Took me a week to finally get it right, but I've managed to get both speed, stability n a Schweeet batterylife
If I get the time this weekend, ill post how I did it, and all the steps from stock, out of the box, to end product

I find that the insert coin rom isn't too bad on battery life. Well version 1.1.1 isn't. not sure on the newer versions though
Most AOSP ROMS have great battery life. But much of the battery life is to do with the kernel too, so picking a good kernel is paramount.
I'd agree on the kernel bit, but also, how you have android configured in general around it can have a noticeable effect.
The right rom, kernel, and also userspace setup/configuration all adds up

Also black background for AMOLED screens is worth adding to the list.
Im curious guys on this battery subject?
I'm currently using aurora V3 but even before that I'm lucky to get a day out of it.
What potential increases am I looking at here?
Many thanks

There is no way to guess or add a multiplier from your rom ro another to see potential increase unfortunately. It all depends how you use the phone. If the screen is on all the time, you wont see any increase in battery life as ROMs and kernels cannot control the amount of battery a Screen uses. This is a constant.
ROMs and kernels optimise CPU so that les spower is used, therefore things that use CPU will affectively waste less power.
The only way to test / compare is to flash something else and use it the same as you do every day.

You could assume stock, then at the bottom add root only and mention kernels and set CPU, autokiller, autostarts etc etc
Rightyo, need to do shopping but will be back shortly
Might see what i can work out
AOSP roms are the best for battery of course, but if you like SenseUi, I recommend You InsertCoin 1.1.4 and kernel from -SNQ, (his kernels are better for battery from bananacakes)

Your opinion needed

I cannot run a undervolted kernel on my evo for some reason, it doesn't play nice. I liked tiamat on my previous evo, was the only one I ran. while I have tiamat running i have about a minute before it reboots. My question is can I use vipermod to restore voltages to stock/stable. If so what voltage should I enable. I'm useing an extended battery 3500, if that makes a difference. Also if that's not possible what kernel do u recommended I flash to get better battery life?
Edit: trying savage 221
Sent from my PC36100 using XDA App
What ROM/kernel combo do you have? how are you flashing them? Are you making sure to pair sense kernels with sense ROMs and AOSP kernels with AOSP ROMs?
I've been sticking with stock Wich is cyan, On miui. I did some home work and it looks like salvage has stock volts by default. Lol yes I'm keeping aosp kernels on aosp roms

Sorry, it may sound like a retarded question for me to ask. But you'd be surprised at how many people are running sense and flash an AOSP kernel, or vice versa. It's always nice to get the obvious issues out of the way in order to focus on what the real cause is.
MIUI is one of the ROMs I've never really used. Make sure your battery is calibrated. That should help a bit with battery life. I'm using Savaged Zen on mine with CM7 and it works amazingly well. As far as the undervolting issue.....I am not too sure as to what is causing that.
What method do you use to calibrate. I've never done that. All I've ever done is wipe battery stats
Sent from my PC36100 using XDA App
Charge battery to 100%, enter recovery, wipe battery stats, let phone COMPLETELY discharge (till it turns off), then recharge to 100% again and use normally.
Cool thanks

Battery Tweaks

I come from the Eris forums, where battery tweak threads were plentiful. Can anyone direct me to such a thread concerning (rooted) INC2s? I'm on CM7, and battery life is so-so on heavy usage. I like to think rooting brings opportunities for ridiculously good battery life, but not w/o some tweaking. Help?
For the most part a majority of devs include there own tweaks into their respected roms. Most will flash a custom kernel which allows overclocking and undervolting. Like I am running miui with areos kernel oc 1.2 and undervolted -50. It is now 9pm and I have been unplugged since 8 and still have 70% with medium heavy use.

I'd rather not pay $5 for something that is only simplifying what I can do myself for free, ya know? I know in the Eris forums they had recommended CPU settings that I could do myself in the CM settings; do we have stuff like that for the INC2?
i usually get at least a day in a half with heavy use. You just need to experiment with custom kernals and different voltages. Not really a simple answer, you need to do the research yourself.
How do I alter voltage? I don't remember that feature on the Eris...

Incredicontrol from the market.
Try Drellisdee's kernel, #21. It's already undervolted and can be overclocked.

On cm7 you'll need aerovans .8 kernel which you can get on rootzwiki. Then install incredicontrol from the market. I undervolted mine 75-100 on all and had no issues with excellent battery.

#1 cause of battery drain: Global mode enabled. Make sure to disable it in settings/calls and set it to cdma only. My battery basically doubled after doing that. I figured that out the first week I had it.
