Rom or Rom+Kernel with best battery duration known?

So ye, maybe tonight or tomorrow a storm will come and probably will have no electric power, I have 3 batteries but just in case it takes long to get electricity back I wanna know what rom or rom/kernel combination has been proved to be one of the bests battery saver.
I know I might get shot by the search police but I made this new topic cuz roms get updated everytime and old searches can point me out outdated answers, plus I need a quick response since the storm might start tonight, thanks.

There's no definitive BEST. It's all about what you do and how well you manage it. I get pretty great battery life with CM7 and LordMod's kernel. But some people have battery drain issues with cm7 nightlies. It's more about you and your phone. Experiment, try stuff out, see what works best for you.

Thanks I will download CM7 now

I recommend using the Nightly builds, it intimidates some people who are new to CM7 but they are really good and for the most part very stable.

I recommend any aosp build. I'm on miui with the lordmod kernel and you can go days if you turn off data, which isn't necessary in an emergency situation like you are describing .

YO Thanks again, CM7+BFSLordmod with the stable puv gave me 10 hours (data/sync off and screen most of the time off) and it was still at 91%!!! thanks a lot.
Im surprised how leedroid and other sense based roms now drain a lot of batteries! maybe cuz of the new sense, I remember leedroid gave me better battery results in the past similar to cm7.

I'd go with ninja its got better battery life and is even smoother

[Q] Why is "Android OS" draining my battery? [Resolved]

Here are some screenshots of my Battery Usage and as you can see my battery is just horrible:

I have done some research into the Android OS draining the majority of the battery and didn't really find anything with the SGS4G, however found the issue in the Galaxy Nexus, Samsung Galaxy SL i9003, Galaxy Note GT-N7000, and the Samsung Infuse 4G forums, and I am sure there is probably more..
Out of all those forums this is the only one that seemed like it could have a solution linking it to:
1. Google backup transport
2. Organizer widget

My only problem, I have neither of those on my phone.
I was hoping that maybe somebody here could help me diagnose the issue. For the longest time I just have thought my battery is getting old and isn't holding a charge as long, or I just use my phone too much. However after watching my Battery Usage over the past couple days makes me wonder if there isn't another issue here.
I am currently running RaverX3X's amazing Valhalla BlackEdition Final with the Booster and FBis251's bhundven's SMS KJ6 v0.2.0 Kernel. I also have installed the BraviaHack and am using the KG4 Modem. I am able to post logs or anything that can possible help. I have used thomas.raines 1-Clink Gremlin Remover following each step to the "T" with no luck of fixing the issue.
I have attached more Battery Usage Stats as well in case they might help.

I'm pretty sure it's your kernel, try antonx kernel, it has better batter life

I will have to give that try, do you happen to know what kernels are known for providing the best battery life? I guess I can always search around and see lol.

I'll have to give that a shot. Right now I'm testing battery usage with airplane mode activated, and the screen off for the next 8 hours. I'm logging battery usage with the BetterBatteryStats app, to see if I can pin point the problem in the first place.

Thanks guys, I have pretty much resolved the issue as I have switched Kernels and am no longer experiencing huge battery loss from anything other then the Display which is just plain normal. I still plan to update over to FBis251's version of ValhallaBlack as I have been keeping an eye on it, and debating when to make the switch.
[On a side note] I'm still not hundred percent sure why the Kernel was giving me this issue to begin with. If I had more experience with Android development debugging I'd love to dig deeper into this issue. However though since it doesn't seem to be a huge issue among other users in the SGS4G forums, and it is easily fixed by using another Kernel I don't really see the need.
Thanks again FBis251, and m0bstr.

Problems with Android OS with Gingerbread and Froyo
I have now encountered battery drainage problems on two different Samsung phones. For a long time my Samsung Captivate ATT running Froyo 2.2 was killing my battery. I was about to buy a new phone. I touched base with Samsung and decided to back up my phone and do the factory wipe.
After the reset and the loss of my apps, the phone seems to be working ok. Even a battery which constantly appeared to be dead, is now working fine and holding a charge.
Today another phone the Samsung Glide ATT running Gingerbread seems to have caught the problem and Android OS is using 25% of the the battery. This is ridiculous.
Normally, about 75% is for display and OS doesn't even show up.
Another person at work had an Android exhibiting similar problems today. This problem seems to be pretty widespread if I know three people with this problem. Feedback appreciated.

Maybe "One Power Guard" can help you downloaded from http://forum.xda-developers.com/showthread.php?t=1889740

[Q] Which ROM's don't have black screen of death

Which ROM's here do not have the issue with the black screen of death? (When the phone will sometimes just not come out of sleep mode sometimes, often when charging or with wifi turned on)
I know that Cyanogenmod has the issue, but what about other ROM's? I'm looking for a nice GB ROM that wouldn't have this issue.

Reborn doesn't do that for me.

Latest baseband, mokee with stock kernel and I never get bsod. I'll have to try with mazouts kernel.
Sent from my LG-P999 using xda app-developers app

I have not had a BSOD on PA CM10 Build 9, v21y, and Mazouts latest kernel yet. Battery performance could be better though.

Thanks for the suggestions. I tried CM10 and didn't like the lack of hardware acceleration. So I'm waiting on CM10.1 for that. Hopefully some of the BSOD issues will be resolved there. In the mean time, looks like I have some ROM's to look at.

+1 for a lot of truth in it! It's also phone-dependent. Not all phones experience BSOD's with all kernels. It's an art to mixing and matching the kernel to your phone that gives the best performance. For example, my phone is SUPER-PICKY when it comes to Kernels. I can't OC my phone above 1.2Ghz or the phone will just randomly reboot. Also, ALL kernels cause my phone to BSOD while charging. I have to enable the preference to never let my phone go to sleep while charging. Before you start suggesting solutions to this, I have tried everything from increasing the voltage of the lower frequencies. I have tried eliminating the lower frequencies while sleeping. All of it. My phone is just a PITA when it comes to charging. I can live with it being on all the time while charging.

Yeah being on while charging is no big deal. How do you do this though? I only found a setting to keep the display on for 30 minutes tops in my G2x running CM 7.2.

your welcome
"Well, bust my buttons! Why didn't you say that in the first place? That's a horse of a different color!"

The "Settings-->Applications-->Development->Stay Awake" trick works for me as well. I'm running cm7 -20130201-nightly on the v21y baseband with the 2.6.32.60-mazkrnl.GB kernel. Without the stay awake setting enabled the phone will still freeze but I haven't had the a problem since enabling the setting over two weeks ago. I also have a Titanium Backup schedule set up that alternates between backing up new applications and saving modified data at 3:30am every night with a device reboot for good measure.
This is the first time in the almost two years I've owned the phone that I've been fully satisfied with it. I feel like I can live out the rest of my three year contract with the phone now without a problem. I guess the note 2 (or a sony xperia device, I can't decide) will have to wait, my G2X still has some fight in it yet.
I must also note that I have never had an issue with any of the ics of jb ROMs. The last ROM I was running was "[Dez 30] [P999][ROM][CM10] ParanoidAndroid v2.56 Hackfest JB [build9beta]." I used it for over a month but the lack of a decent camera, no video recording ability, wifi drain, general battery drain and battery indication problems eventually became too much. The ROM itself was stable as a rock but the small issues become too much after a while.

Battery
I Found Today Phone Started Acting Really Sluggish & Freezing

It was a little laggy after the update and ran a little hot. Booted into recovery and wiped cache. Worked fine after. Can't tell how battery is performing yet

Why won't mine install. Keeps saying it gets interrupted.

I'm not having any problems really. The only thing that's really bugging me is that SELinux can't be switched to Permissive on Lollipop. Also, the battery life isn't so great compared to Goldfiner v9 on Safestrap. It's feasible though. That's really all I can say since I've only had it for a few hours.

Battery Life and Performance
My phone has been faster than normal, all the transitions are smooth, haven't had any errors, and all my apps seem to load quicker now. Battery Life is a little better not to much but I have some Heavy Usage at time but it is still running good. Some of the old bloatware was removed but you can disable most of the bloatware you don't want. Reset your phone before you update though as it will help with better performance.

Anyone have any suggestions on what I should do? Not rooted.

Well that acutally depends on the number of installed apps and homescreen elements also seem to drain ram. Take a look on my results:

My phone seems to be a lot faster and not as much of a drain on battery, but it seems to charge MUCH slower now for some reason.

what's the point of a custom kernal?

I am fairly new to rooting and have the op7pro rooted and was wondering what the deal is custom kernals and what the benefits are and how hard it is to use one

Its modification of the stock kernal that can provide extra features, improve performance and battery life. They all are a bit different and there really inst a better one of them all. Its all personal preference so I recommend giving them all a try for a few days and see how your phone performs.

Kernels allow you to modify the governor's behavior or use alternatives, boost parameters, clock speed, memory thresholds, block wakelocks, under or overclock, etc. They're often accompanied by newer drivers (ex. Wlan from CAF), Linux upstreams, fixes from QC, new features like k lapse, and so on.
CPU governors and boost can be tailored to be aggressive or passive. I'm more concerned with endurance than scores, so the latter suits me.

I have mixed feelings on custom kernels nowadays. I used to be enthusiastic, but eventually realized that every rose has its thorns. Some custom kernels are truly excellent on certain phones. Some phones just don't play nice with custom kernels, and you could lose features until you flash a different kernel. Modern Android stock kernels are stock for a reason, in the same sense that some wearable things are "one size fits all". The good thing is that kernels are super easy to flash on a bootloader unlocked & rooted phone!

It is easy to flash and it has an app to change setting.

What all have you disabled/done to achieve this?

That also means nothing without the battery graph as the user could have partially charged the phone and that doesn't rest anything until the phone is fully charged to 100%. Not saying he can't get that, I'm getting 9 to 10 hours sot per charge. Just need to show the battery graph too.
