Help chosing rom for battery life

Hi. I usde this as a secondary device, usually at my summer house in the country. Its usually connected to tethered phone wifi from about 10-20 meters away. I find that of the roms ive tried, all have herrible battery life.
Ive tried cm based roms. I recond battery issues are from the couble tap to wake. And from the wifiap. But atm im on aokp and double tap to wake isnt disablable.
What do you guys think? I really dont need to be charging the damn thing twice a day just from light reading and g+.

To get better/best battery life you have to do extra tweaking... Adfree, droidwall, greenify, custom kernel (no UV @ the moment though) etc. to really get any enhancement.
Otherwise rooted stock with same tweaks (+debloated) would be the other option to try

In the end ive settled on AOKP.

Best kernel regarding speed & battery life?

There are a bunch out there with elementalx being the most acyive one discussed in the Forums.
What do you think? Which is the best kernel together with stock rom regarding speed and battery life?
(Speed = snappyness while using the phone, not fps numbers in heavy games.)

Depends on the settings you use and how you use the phone.

Ofcourse my question is when comparing to stock kernel.

You are better off giving one a spin and making your own mind up

If someone has tested both the stock kernel and a custom kernel i would very much like to hear their opinion between these when it comes to overall speed and battery life.

i think stock is the best .
I tried :-
1) [KERNEL] [blu_sp rk r162] - No luck , WiFi doesnt turn on . Even tried reflasing stock rom and all possible fixes .
2) elementalx . Overnight drain is pretty impressive its just 4%.
But the active hours stats doesn't look that good. No audio mods , I really wanted to bump up my headset volume.
might go back to stock kernel by today evening.

Elemental kernel is good for standyby times if you arent a heavy user. As on my usage i got around 4 hours of SOT with my usage but stock gave me around 5 hours..!!
So as of now stock is way better

Well flash the different kernel and play with settings if u want and see which kernel suits u. Comparison with different roms and kernels are not allowed in XDA. They are best in their own way

R162 ?? the latest is R73 and wifi is working fine on bluspark
btw if you want audio mod, you can try DolbyAtmos Mod on top of your elemental. It kick the audio pretty nicely

Headphone gain is back .

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?

there's a "miui smoke rom"using this kernel, maybe you can try that rom, it's also using this kernel

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..

Which one is the best kernel for RR rom?

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.
