I am a big fan of custom ROMS, to be more accurate cyanogenmod. And I like it just like that, without changing kernel or other mods. The downside is it not supporting bln.
Nowadays I am giving a try at Cyanogenmod 11 M9 + Gustavo_s Kernel just because of bln but I am not happy with battery.
So my question is why don't major custom roms support bln? Since our device has no led i see this as a great feature.
most likely for battery saving, having 2 leds always on when you have a notification will and does drain your battery can cut off a significant amount off my battery life

This will likely be a controversial topic, but I'm going to risk it.
Also note that this is not meant to be a jab at kernel developers, or an attempt to lick CM developers' balls.
I have just been thinking. Custom kernels often claim an improvement in battery life or performance with their kernels. With Samsung ROMs, this is believable. The case of the fuel_alerted bug not being fixed with Samsung ROMs is an example that Samsung kernels aren't the best.
However, with Cyanogenmod ROMs you would think that the developers of CM would know best, since they *probably* work far more intimately with the code than custom kernel developers. Has anyone found an improvement in battery life with a custom kernel as compared to the stock CM kernel?
Now, I'm aware that custom kernels offer some features not found in the stock CM kernel, like how dual-booting is available for Siyah. But let's focus on battery life and performance for now.
Again, this is not meant to be a flaming thread. I genuinely wish for a conducive discussion on this topic. Lastly let me express my appreciation for both CM and Kernel developers, for devoting their own free time for our sakes.
Thanks!
I'm not sure if this is what you are looking for as an answer but a tweak i've used to give better battery performance is CPU FREQ_MIN. This is the frequency below which the 2nd core is not used. I don't believe you'd be able to use this tweak without a custom Kernel

It helps, thanks Personally I would prefer to try to quantify battery life with different kernels myself. Most phone review sites choose to test battery life by looping a video, however I do not believe this accurately measures battery life.
If anyone knows of an app that loops web browsing I will be happy to test it for myself.
I don't even care for extra 10 minutes battery life. If you want extra battery life don't use the phone. Lol.

Hi guys,
I've been using many kernels now, Siyah, Franco, Yank.555, NEAK. Etc. But They all used up my battery like crazy! lost 8 % in 20m thats not good, Mind that i wasn't doing anything, it was just on screen lock. Now i've read that media scanner could be in wakelock to use so much battery but how do i see this? And my main question is, what is the best kernel for battery use but balanced with stock performance? I've heard phenomenal would be good, but i rather ask before installing another kernel by now.
I'm running sotmax ultimate stock v14 for gt-19300XXELLA jelly bean 4.1.2
Thanks in advance
It's against the rules to ask that
Why don't you try stock kernel? I have a good battery life. Try to close all battery-sucking apps like Facebook,Istagram and stuff like that.
I don't exactly think it's up to the kernel to save battery life. I'm using siyah, but, to give you an example, its battery saving features are undervolting. Meaning you can either make it have top performance, or set it to the highest battery saving setting.
Best kernel, best rom, and hottest chick in the world threads are not allowed as they are all subjective

Hi,
i've just heard that my s3 isn't going to recieve kitkat so it is time to flash a beautiful custom rom. I definitly want cm11 on my phone (temasek or m6). But i'm struggling to find a find a kernel that solve the biggest issue i got with my s3, it pronounced green tint. I now it is because oled greens use less battery and last longer but i really want accurate color reproduction (maybe even a bit oversaturated). If i remember correctly andreilux did a full callibration in its perseus kernel but that kernel isn't compatible with cm 11. Anyone who nows a good kernel that got that implemented?
i would recommend this one, using it by myself. It got vast amount of color settings under mDNIe tab. Latest version doesn't include STweaks for kernel control, but you can download one from Playstore (I think it is the best for this kernel).

You should do compare and contrast on all available roms, that is stable enough to be used as daily driver. We all don't have the same usage in daily lives, we have different apps, which is depends on the user, different battery/performance mods, kernels, power management, etc. Just try LOS, Pixel Experience, etc. and record your power usage and compare it to all and you can determine yourself which one of them is good for you.
Btw. I'm using stock MIUI cuz I don't have problems installing custom kernel, battery mods, and other tweaks.
ROM has little to do in battery life (I agree, a few ROM specific features consume more battery like AOD). It's more Kernel related.
To my experience, stock miui ROM is always the best in terms of smoothness, fluidity and stability. If you feel the battery life is not that good, just grab a custom kernel and flash it through TWRP. You can also debloat useless System apps in order to have better RAM management.
I haven't tested everything, but stock kernel and stock ROM works the best for me. Most stable, best performance, smoothest, best battery(I get 10HRs of SOT). You should re-calibrate battery if you have been flashing many different ROMS.
Thanks guys i am on stock stable miui with sphinx kernel i am happy with it but i want to to try stock aosp that why i ask
For custom rom, you can try crdroid. For me so far thisbrom with default kernel has great battery backup. Manage to get 8h ++ sot starting from 90% battery. I will test more with next battery cycle. Normal usage social media, youtube and so far not try with pubg yet
Hi, I'm a big fan of LineageOS and use the standard LOS kernel without rooting my phone. I want to have a kernel with wireguard support. I don't care about any other feature, only stability and battery life. So I guess the less changes the better.
Is there a comparison somewhere for all the available custom kernels for beryllium?
I've never used a custom kernel before, which one should I use?
Thanks!
