I've tried out a variety of kexec kernel roms on my xt912 and I can't seem to figure out how to get good battery life on any of them. I use cpu sleeper and hotplug but neither of these seem to help much I've also tried underclocking and using a custom kernel with subpar battery still. Any tips? I really like the added features but can't deal with the poor battery performance... Thanks for any suggestions!
For my kexec'ed phone, 24 hours is the limit....

Well generally battery life on kexec is worse than on stock kernels. But you might want to try JBX Kernel - it works great and gives great battery life with decent performance :]

I tried the JBX Kernel, the most recent hybrid version, and was getting pretty bad battery life and seemed to lose more battery with the screen off then on, what settings do you use?
Sacuraktive governor + sioplus scheduler, heavy undervolt (down to 830 mV), frequency lock at 100 mHz/1 gHz. You also need to remember that it's best to do a clean install on the first jbx kernel flash.

I have to disagree. My battery life is much more improved with cm 10.1 (hotplug and noop scheduler) than with stock kernel. Moto has much **** going on in the background
Well don't mistake stock kernel with stock rom. Battery life on debloated roms with stock kernels is still better than kexec.

I have not tried that so I can't give any statement but stock "rom"(retail.eu) with stock kernel doesnt have that good of battery life
Battery has been an issue since day one with the RAZR. Kexec has been a bit hungry compared to stock. Juice defender helps quite a bit.

Hi there
i have my galaxy for a few wekks now and i find battery on CM9 RC2 pretty bad (underclocked and undervolted)
which rom is recommended for good battery life (and works with siyah kernel)
GPS/WIFI/MOBILE DATA/CAMERA must be working !!
thanks for your suggestions
I was using xwlpo stock, only rooted. Undervolted -25 and set cpu to 800 mhz. The governor was ondemand. The formula of amazing battery life. Now i use jelly bean which wastes battery.

No two people will ever have the exact same setup, and even if they miraculously did, the likelihood of their two phones coming out of the factory exactly the same is infinitesimal.
So a ROM that someone else experiences good battery life with, may be terrible for you or me.

Try rootbox with dm kernel. It has pretty good battery, but like previously said every user is different and therefore will have different battery life. It would not surpise me if this gets closed very quickly.
Hi guys, as title say, i want to know wich kernel is better for battery life..
I´m on Unlimited ROM, by mv style, wich is really awesome. I´m using Mesa Kernel, but i read that Panic Kernel is good for battery life too.. And performance is also good. So.. wich kernel do you suggest me? Is Panic Kernel more battery friendly than Mesa?
Thanks
My Phone is a Mini Pro
I have never used MESA kernel so I can't compare the two
But kernel PANIC has good battery life... Better than rage and Kamarush v3 (no offense) (just my observations)

Get battery monitor widget from market and test those kernels yourself.
It's better to yee for yourself then to blindly trust
It's easy to do, flash kernel a and leave the phone in standby during the night. In the mornign look at the battery consumption graph in BMW.
Then you take kernel b and do the same with it.
Just be sure to use the same min frequency and same governor.
EDiT:
A ROM also influences battery life. So let's say that for user B MESA has excellent batt life, for user A it might be bad.
That's why it's better to test and see for yourself

Personally i try and aim to use a 'lite' rom + panic kernal if possible ....
But most phones give about 1 day worth of work. There are few that exceed that (ultimate? rom by mv_style)

I have a i9300 and I really like this ROM, has everything i need except one thing: My battery is going out pretty quickly compared to previous ROMs i used (Foxhound for example).
I want to keep using it, so is there a good way to get better battery life? I'm using the default kernel that comes with the install because I dont know which ones would work with this ROM.
Any sugestions guys?
Thanks!

You can try to flash a Kernel that supports underclocking and undervolting of your CPU like the Temasek Kernel. Also keep an eye on what causes the massive battery drain. You can install a CPU monitoring app to see what`s using your CPU the most.
Also what do you mean by battery drain? Do you make it through the day?

It's not really a drain, but I barely get through the day.. while with the same use i would end my day with 40% with foxhound.
In the normal battery control it says its 40% android use..
I was looking to flash a new kernel for my poco f1.
I search for a bit and find out that people consider those 2 the best one out there
Can someone explain me which one is better and why?
Sphinx has better performance but runs hotter than Franco this is because Sphinxes clocks are higher.
Franco has lower clocks so you will see minor stutters in games but it is clocked lower than stock. While only francos gpu is overclocked.
Both are stable in all applications no crashing.
it's not overclocked on franco. and it's a bad idea to overclock when it throttles anyway at load. it will make things worse. you could actually get better performance if you underclock...

so in your opinion which one is better for battery life?
I'LL go for franco anytime.. of the day.. both are superb in performance.. but im getting longer battery life with franco.
Franco is a great developer, buy he doenst use f1, just develop for it. Sphynx is an f1 user and his kernel is better polished, i have better battey with it. But there are lots of good kernels here, now im using shadow kernel, it is very good too
kernels don't really matter for battery life. unless using drivers with issues, which isn't a problem on a poco.
if you're using miui, debloat services and processes that constantly report to miui and wake your device.
limit apps push notification and background access. disable sync of non essential services.
personally i don't believe in using battery saving profiles and tweaks like LKT and messing with CPU governers and I/O scheds, but you can experiment with those if you need more battery at the expense of performance.
also try to optimize battery for any service/app you don't need realtime sync for (or don't need it to stay running in background). can also try the google play services gms doze module.
use adblocking browser like Bromite / hosts file to prevent ads from loading will also help battery times.
all of these have far greater effect on battery than kernel level tweaks or differences.
To be honest, the kernels I love are not the two. I actually use Shadow and Twisted Prime. I am currently using Twisted's kernel because, in my use-case, it actually provided me with better performance and overall battery. However, Shadow kernel is also good because you can add tweaks that will make it even better.
After being with franco kernel for quite a while.. im.now.trying the MALAKAS or MLX kernel.. and im telling you bro.. this one's damn smooth and effficient too.. wow. Just wow..

Lol are you in dreams ?
Franco is the most power hungry kernel.
Evel the stock is better than it.
Without using any underclocking.
And after underclocking it gets like 2+ minutes in battery life and makes the phone's performance ****

What kind of tweaks..
Just wanna report that Twisted is the most balanced kernel that I've tried.
Sphinx kernel has a better performance than Franco, but the device will be hotter. If you're in a tropical country, the temperature may stay between 40°C-45°C in Sphinx. Franco saves a lot more battery, also low temperature, but I don't like the performance in games, but it is better than the stock kernel.

What is this? Some sort of competition? Ask your question in a more appropriate way whether you want better performance or better battery life. Both kernel serves different purpose.

That's quite the opposite. Francisco owns a Poco F1. Infact he was provided the unit by Xiaomi, afaik. On the other hand, Michael doesn't have a Poco F1. He owns a Dipper (Mi8) which share similar hardware and software with Poco F1.
So I just unlocked the bootloader of my one-week-old Poco F1, flashed LineageOS 16, and everything has been smooth sailing so far. Now, I want to flash a custom kernel. What can you recommend for a good balance of battery life and performance? I'm not really keen on tweaking parameters so I want a flash-and-forget-it solution. Thanks in advance.
Sphinx works best for miui and lineage.
Franco is also up there
Canting kernel. At first I was flashing a different kernel daily. I found Canting and have been on it for nearly a week. Super stable. Not 1 random reboot or freeze and it also has vibration control, sound control, display control, Klaspe and just about everything else
https://github.com/khusika/canting_kernel_xiaomi_sdm845/releases
Sphinx Kernel is a good all-rounder, if you want a 'leaner' kernel go for Simple Kernel. As for performance, I've heard quite some praise from Malakas Kernel but I can't guarantee anything. An honorable mention would be Canting Kernel.

Arter97 kernel is good for balanced performance and battery life and its very smooth

I use lineage stock and have been getting ~8 hours SOT with light usage, over 48 hours between charge. The gains/losses in performance and battery life between kernels were negligible for me in real world usage and sticking with stock is just one less thing for me to worry about when updating.

Yep, might as well stick with stock I guess. The development done into these kernels is very active that some even update every day. I think it's too much of a hassle to me to flash a newer version daily.
I also like to believe that wiping cache frequently, which is a prerequisite in flashing, hurts battery life, because the phone doesn't get to compile it and as a result, keeps on running background processes to rebuild it every time you do so. What do you think?
Go for FK. 8 hours sot while playing PoGo non stop on 4g. Very good performance and non heating issues so far.
Just wanted to update this post based on my findings:
Franco: Awesome battery life, though the device essentially becomes gimped. I'm not a fan of underclocking.
Malakas: Best performance by far, and also pretty good battery life. A bit unstable, though.
Sphinx: A good balance between performance and battery life, though idle drain is a bit high. Will test a bit more.
Not willing to test arter's since it's SELinux Permissive.

I'm running Evolution-X with the Optimus Drunk Kernel. I have the NVT panel version of the Pocofone and my experience has been excellent. I also service a FTS panel version of the Pocofone, that had the freezing problem, and the Optimus Drunk Kernel really helped turn the phone from a freezing/frustrating nightmare and a similar experience to the NVT panel version. I recommend both the Evolution-X ROM and the kernel. Currently, the default kernel on the ROM is the DERP kernel, which is also good.
Nowadays I just stick with the stock kernel
