Best battery 4.2.1 rom kernal combination

First of all.. A very happy New Year to all
Ok.. There are many roms on xda and kernals too
If someone has figured it out.. could anyone tell me which rom-kernel combination is the best for battery (and settings to if needed)
Thanks in advance

There is no such thing as best. My phone and your phone are not identical, even though they may have very been from the same production lot. Nor are the individual circumstances under which two given people use their phones identical. Something that performs extremely well on one phone may very well boot loop on another.
Do some research by reading the applicable dev forum, and then try some different combinations for yourself to see if they work for you under your unique set of circumstances.

I am using Cataclysm ROM with the inbuilt kernel that comes with it and I am completely happy with the battery life.
I could get 2 days out of my device on general usage.
You could try that.

I REALLY doubt you will get the BEST battery performance out of stock.

KERNEL.

there is no best combo, there is only the best combo for you and your device. for me its rasbean jelly rom with trinity kernel. but whats best for me and my device might not be right for you and your device.

I've been using cataclysm with Franco kernel for a while and have been very satisfied.
Sent from my Galaxy Nexus using xda app-developers app

Agreed, there is no best. I've had good luck with muzzy's aosp room and Trinity kernels. But you might not like that combo. I'm not interested in gaming for instance, so my needs might be different than yours. Try different combos and you'll discover your own best.

Ok.. got it.. thanks everyone

stock rom is the best in my opinion

I think Xylon (014) with the default lean kernel gives good battery life. Tried the ROM with Franco 358 but i went back to lean.
Also, i make site that my most of my apps aren't running in the background and using up the battery... That's what the FAQs from Franco's OP in his thread mentions.
Sent from my Galaxy Nexus using XDA

I get over 5 hours screen on time and a flawless smooth ROM with heavy usage with both data and WiFi on with xylon stable and ak purity kernel running Wheatley gov. I just addressed this on the xylon thread. Works well for me and some others.. Have a look its worth the flash to see.

Best I have found is stock.
Sent from my Galaxy Nexus

Check my sig. I can't use any rom other than paranoid. I've tried many different kernels, but i keep going back to Franco.

Whatever combo I use, no more than 2hrs of screen time and 16hrs of standby.

I had great luck with Xylon (latest) with Tiny (latest)
Just flashed Evolution 3.0 and Lean Kernel (latest) and after 2 days I am satisfied.
Good Luck.

For me it's I've been on Muzzy's French Vanilla on stock kernal. However, I've read good things about tiny's kernal too but I haven't tried it myself.

As a noob in the android community, and after trying different roms, i like rasbean the most for different reasons, but on choosing a kernel, for example trinity, there are a lot of options. What's the difference? I really not get it :silly:
for example, TNP1536-512-JB-4.1.2-STABLE67
So this one is max 1536Mhz CPU and max 512 GPU i read on derkernel site
So there's a different setting for graphics (gpu)? I always tought CPU was working between 1536-512 Mhz?
And euh, when i have trinity's app, i can change the settings of this kernel to get this one? (TNP1344-384-JB-4.1.2-STABLE67)
So this is the same kernel but with different settings?
Please make me a little bit smarter

moved

please close

Btw alcohol was used to create this. Might be flammable.

Awesome, is there a slight rundown of what this has to offer over stock?

well, it may or may not be faster/more battery life. its a test kernel to find build method and make sure things are going to work before putting 1000s of lines of code changes in

Sounds good. Flashing now, will test as much as I can.

Will test also thanks

So far it seems to be running well. Run Quadrant and it is using Eco mode as my scores varied by 2000. Don't care about scores just the feel.
The governor is ondemand and uses 1134 alot more. Which is nice not seeing 1512 mostly so battery should be better.
Do have a question though. Do you want us to test different governors? If so, what's the preferred program?
Thanks joker!! It's great to finally have a kernel to play with!!
edit. Decided to use Set CPU. Seems to be working fine. I take that back about using 1134. Guess it just happened to be the speed of choice by what I was running. Still mostly 384 and 1512. And of course Deep sleep

This has worked fine in my testing Bluetooth steaming and calls work without issue. Camera works so does WiFi. I still see the msm host wake lock but it's not that high. Got 20 thousand in antutu so it seems to work without issue.

I didnt do anything to the govenors on this release. This is mainly a basic kernel close to stock with a couple tweaks.

It won't get rid of wake locks. They do have a purpose, but it should reduce them. Hopefully

Flashed no problems. Chuckled at "raping malware" and "licking ICS." We'll see what happens after it settles in over a few days.

So far everything seems to be going well. No stability issues, camera and WiFi work fine, everything runs smoothly. Though its hard to see if this runs better or not since it ran pretty well from stock.

Woohoo! Good to see you back Joker! I was a religious follower in the MoPho forums. I don't post very often but I just wanted to say it's good to see you and I can't wait to see what you do with this ridiculously powerful phone.

I never released the kernel, but yeah I reverted those oc's and decided to handwrite it. Plus I wanted to update stockish.
So Dont use octest1. It was a test.

The gpu/avp/mem/cpu/etc etc will be underclocked and undervolted. sort of a "hey we have way way to much phone and everything is designed for slower crap anyways so lets also go slow" kinda kernel

agreed. i've found that lean or kor kernel works best for me.

:good:

Not sure why this was bumped but in case anyone is still following along, all kernels preform differently for all devices. Your best bet is to try them all. When I have a new device it may sound weird and all, I flash the kernel with the most thread views and try them in descending order. This way you are trying what appears to be giving most people the best results and if you don't like your results ,continue your venture.
For Touchwiz I prefer however kt747 simply because Team Kernelizer has some awesome files for undervolting. The other kernels are pretty swell too.

BENCHMARK SCORES! - post your best scores!

Lets all post our Benchmarks!
I am using Antutu Benchmark found at the play store for free
I am currently running the Infamous1.5 ROM based on android 4.1.2
with the Infamous kernel .7.4 by Jamison904
BTW... I have about 85 or so personal apps installed in this mod
I am also running the World Weather Clock Widget at the same time
and I am not running any kernel tweaking software...
here is my score...

btw what is benchmark?

a benchmark is basically a set of tests to see how fast your phone is running
here is the dictionary meaning...
bench·mark
/ˈbenCHˌmärk/
Noun
A standard or point of reference against which things may be compared or assessed.
Verb
Evaluate or check (something) by comparison with a standard: "we are benchmarking our performance against external criteria".
if you want to compare your device to others
go to playstore and download Antutu Benchmark and run it

I know my device would score low...I'm setup for stability and battery life.
Those with really high scores are tweaked for Max performance and probably carry an a/c charger in their pockets!

Stock kernel. Both Cpu cores underclocked to 1.35 Ghz
Btw about 115 personal apps no mods at the moment.
Aaaaand with only one hour of screen time this is the battery life I get.

Actually I posted a benchmark and mentioned that screen was on for one hour. It was mainly a response to an earlier post about high performance means battery sacrifice. More people on this forum need to learn the balance between power vs stability/battery. Not directed at anyone in particular btw

That's great and all, but hardly surprising. It's about double in scores because it has double the cores. Personally for me this would have no positive effect on my phone usage, but I would have a worse camera and have to use an lcd screen.

Yea.. not for me. A much faster phone would be nice. The Nexus 4 is much faster and smoother on all fronts. I've had 3 t989s and the camera is absolutely nothing to write home about. Compared to an exynos powered GS2, the sensor on this camera sucks.. and don't say theyre the same because they are not. SAMOLED is awesome but outdoors it's a pile of sh*t.
Point is, to each their own.

First of all I searched the forums
And if I missed something I'm am sorry for being a noob! (And stupid)
I'm not really enjoying kernels I'm not very good with UV and overclocking (not comfortable in doing so)
I'm jist curious what ROM you use (TouchWiz I need tmobile wifi calling)

My phone drains 0.2-0.3% per hour on the stock kernel (on wifi with a decent router). The TW custom kernels are not worth using, in my opinion. Now AOSP on the other hand... yikes. Pretty much have to use them.

You might want to take a look at your wake locks. If you are having that drain while the screen is off, it most likely a wake lock. Search the forums for better battery stats.

I'm running HyperDrive Rom and Ktoonsez Kernel. I have tweaked much of the cpu frequencies and used the ktoon governor. However, my battery life compared to the stock rom isn't that great.

Every phone is different so will run different on your phone. I do recommend Dandroid. It now has wifi calling. Complete based on T999. It used to be a port. It's super smooth with great battery life. And it's Cyanogenmod themed.
Sent from my SGH-T999 using Tapatalk 4 Beta

There are no "best" rom/kernel combinations for battery. It varies from phone to phone. You could try testing different TouchWiz roms and kernels, but remember to make a nandroid before doing so. Some roms you could try are wicked, stockorama, hyperdrive, etc. For the kernels you should use the stock kernel for stability or ktoonsez.
