Recently I have been facing a bit more battery drain n heating issues with RR rom which I didn't experience before. So I wanna try a third party kernel. But I don't find any suitable one in the forum. Almost all seem to work with sense based rom. So can anyone help me out here?

The three I've tried are tabp0le's kernel, Elite Kernel (AOSP), and Nebula Kernel. Below are my experiences:
1. tab's kernel: Best battery life, good performance. Vibration intensity settings work at first, but will go back to default when notifications are received.
2. Elite Kernel: Think of this as a baseline kernel. Good all-rounder, everything works well, including cameras and vibration tuning.
3. Nebula Kernel: The fastest, bleeding edge of performance. Battery is a bit worse in my experience, and some versions of the modified Google camera that are floating around don't work. Vibration intensity settings are adjustable and stay adjusted.
These are just my findings, battery life is measured by EX Kernel Manager's active and idle drain per hour measurements, which change based on what you're doing, so nothing scientific.

at the moment i use the android revolution hd 6.0 rom with a perseus 29.1 kernel. the battery drain is 1,5%/h (betterbatterystats: 2d 42m battery 25%) and the cpu setting is stock. i will see if it change after the next charging.
i already downloaded the redpill rev1.00 kernel and i want to test it the next time.
unfortunately i've got some l2_hsic wakelocks with the perseus kernel (2h in 2 days) and will see what happens with the redpill kernel.

ROM and Kernel have only a small effect on battery life. The main culprits are processes that wake the phone up from deep sleep and engage the CPU or data transmittion.
When I lowered all auto-update intervals of apps from once-per-30-minutes to once-per-4 hours, my battery life nearly doubled itself.
i presume that you already disabled/lowered these "useful" things to improve your batterylife.
i don't play games on my cellphone, just some surfing and calling on viber (2-3h per day) however my battery lasts longer compared to the stock rom.
Hi,
since a week I have the rom on my xperia pro. It is very fast, no problems. Only bad battery life. I use the kernel from the zip, 3.4.62-nAa+ [email protected] Sep 26 2013.
Can you help me? Which 4.2 or 4.3 ROM is much better in battery life? Which kernel can I use with this roms?
Accu consumtion shows 55% display. The brightness is on minimum, like 15-20%, backlight for buttons off, backlight for keys 25%. Is this a true treshold (55%)? on my stock rom is was 5 - 10%.
Is there a principiell difference between speed/battery-life on 4.1/4.2/4.3 android versions?
Can I change kernel (I know how to install) without news rom installation or wipe all/data/factory? should I delete dalvik cache? Is it enough?
thanks a lot! I hope you hae tipps for better rom AND battery life
best regards
samu
Same problem here
I'm sorry, i can't give a solution,
furthermore i am looking myself for a reason.
I have exactly the same problem with my MK16i, same CM-Version since about a week.
With a maximum use of approx 20 minutes a day, the battery hardly lasts 24h!
What is this? I see no "big" background processes running. Display : 35-40%, hibernation/ idle: 35-40%.
As if something is working in the background to make me insane!

1. Please don't compare ROMs for battery life, test them out yourself as comparing of ROM is not allowed.
2. Either use kernel in ROM zip(img file) or Raven's Dark Kernel. No other kernel will work with CM10.1
3. You can change kernel without flashing a new ROM, but the kernel must be compatible with the ROM or it will not run.
4. To save battery life, turn off your data connection when not in use, dim the brightness of the display, kill all background processes.etc. Please search for ways to save battery life.

If you have root, use greenify.

CM10.1
I use cm10.1 LegacyXperia with the darkKernel and with the Nova Launcher. Actualy I think this is best combination für performance, battery life and stability. I tryed beansteak 4.2, 4.3, LegaxyXperia 10.2 and others.

I'm lazy. I have already completely described the installation. May be later
Thank you for effort. Could anybody compare with F1xy kernel?
Thanku @Artemka2008 and @Dblm4pda

Btw Anyone tried antutu with this kernel ?
So far, so good.
I did not yet install the custom powerhal or whatnot. What does it even do?
FYI: You have to reroot the tablet after installing this boot.img.
Anyway, of the performance profiles the high is the only useful if one watches youtube. All other profiles results in occasional jerk/lag in the video.
Deep sleep battery consumption so far has been minimal for me. Usage battery consumption might be a tad higher, at least with the high profile, which is the only useful one unfortunately.
This kernel like f1xy and Foxy all suffer from the same wifi problem that when you wake the tablet from deep sleep and wifi is turned off (wifi option Keep awake: never), it takes 30+ secs for the wifi to activate and reconnect. You can't even enable the wifi by yourself during this time, you basically have to just wait...
I haven't run any antutu etc test cos I don't care what the numbers say. All I care is how it works and feels and how the battery lasts.
I'll keep testing.
I am running LOS14 with the new blobs. Which reminds me, I think I get more of the graphical glitches now than I did before. But this all too subjective atm. to say conclusively if it is the kernel or not.

Problems with wi-fi are not due to kernels, these are the problems of the system

I am not sure what you mean by "system" in this context.
The particular wifi issue I mentioned above does not happen with a stock kernel, only with custom kernels. And it is the only wifi issue I have encountered. No breaking off, nothing else, just a slow reconnection after deep sleep. But if it is a necessary evil while changing the kernel, so be it cos with stock kernel I have much bigger problems and I rather use a custom kernel to get more fluidity of use.
Spassiba for the kernel komrad!
does this kernel support vulkan API?
I ran into a same kind of issue I have with stock kernel; After waking from deep sleep the mipad is usually slow as hell for a minute or 2. Like everything is lagging. A bit like a cold engine which is warming up.
Anyway, I moved back to F1xy cos of this which doesn't suffer from the same issue.
Does this kernel support MIUI?

I use OOS 4.1.6 With ElementalX 3.0.5 Running for a while now battery good for my usage no lags and stutter is to a minimal
Battery life is very subjective to your usage e.g. Rogue apps in back ground, Cellular signal. WiFi etc etc
Best thing to do if you don't mind restoring every now and then is to try different setups Roms/Kernels and see which works best for you

Open Beta I'd go with Dorimanx or Bluspark
Stock you can use Elemental X, Dorimanx, Franco, Boeffla, Bluspark.
All of them give better battery life than stock kernel its more of a problem of what mix of features you want, try them all and come up with your favorite. My usage will not be the same neither will my preferences, so test and decide.
Bluspark, eng.stk does an amazing job
But which kernel works with ambient display 2 of ob19/20?
I think none support the double tap to wake feature in notifications. I have to wait for the notification to go away and screen to switch off. Then double tap to wake works.
I like blu but dude get flashing like crazy, Franco is great also
Hello, which rom and kernel are recommendable for that time ? I want battery friendly and don't overheating so much.
Thanks,
Best Regards

Latest aosip rom with nebula v10 is the best I can do when it comes to battery and performance, you'll need kernel auditor or ex kernel manager to get 100% the best battery possible my friend.

@Dlind could you help with the setup that you've found working the best? So you are running latest AOSiP ROM and Nebula EAS kernel, so how's Nebula compared to the one which is included with the ROM? What kind of tweaks you've applied with kernel configuration apps? Anything else?

I like the kernel in the regular aosip. But what nebula has over the aosip regular kernel is, the cpu governors. I've ALWAYS, ALWAYS, ALWAYS! had issues with sched/schedutil. They lag with youtube. And are biased toward power to much for my liking, but if you don't watch youtube much that's ok. But sched/schedutil also has given me the best results when multi tasking. I personally love cultivation. Its a smarter version of good old interactive. There's also options for using a slight over clock to cpu and gpu. Also with this kernel there is an adjustable throttle for when the cpu overheats it in Celsius btw. All these settings are in ex kernel manager and in kernel auditor, they both are great apps. Under cpu mic spot in the bottom turn off perfd and leave wq_power_saving on.

There are some advantages leaving perfd on. Search it on google..
