Hi everybody,
i´ve started this thread because of getting a view of your experiences of good kernel rom combinations. For every user there are different expectations so i´ve decided to categorize in 3 different sections.
1. Battery Usage
longest battery lifetime - depends on each configuration sure but where did you get the best goal for you
2. Performance
based on user experience - not benchmark
3. Usabiltity
your favourite combination for daily use for balance of performance and speed
Please post for which category you provide your post and write some comments why this is the best combination for you. So let's start to share your experience
:fingers-crossed:
I will start
Battery
For until now is the best combination for battery saving for me this:
Rom: Carbon Rom 1.7
Kernel: Matr1x Kernel 9.0 (non overclocked)
Changing kernel from stock of carbon to matr1x pushed my battery life huge. At this time this is the best combination for me for battery life

Nice idea but:
1. Users all have different setups regarding installed roms,apps, widgets, mods and usage.So its very hard to compare screenontime/batterylife.
2. By performance you mean synthethic benchmarks or user experience?
3. Usability! What do you mean exactly by that?
As said don`t want to nitpick but specify the parameters
Me personaly i use Stock 4.2.2 rom and Franco nightlie r148.

it´s very difficult because of individual configurations and impressions and everybody has to test it on his own but i think it´s good to get an experience what other users prefer Please add a category if it´s possible. That would be nice!
I´ve specified the parameters a bit.
For me PA&AK kernel is the best...I came from Galaxy Nexus btw..

Nexus 4 battery best battery life
So i'm running P.A 3.60 combined with matrix kernel 8.5 on my nexus 4. I used trickster mod to change it to 2 cpus in use only and its still silky smooth and handles all the games i play still. With Gpu overclocked and limiting the 2 cores in use to 1Ghz when i'm barely using the phone plus display set to about 50% brightness (mabye too high for indoor use but i just love the screen), i got 20+ hours with wi-fi on constantly, and using social networks (facebook, whats app, sent about 100 sms in the day, plus 4 hours of call time) with 18% left. I think thats good enough

thank you for your settings. can you detailed explain what modifications you've done in trickster mod?
CPU Cores max frequencies / 4 Cores or??
GPU Cores max frequencies / limited to number of cores?
I want to mess up my battery life
thank you
I use Stock ROM and faux123 15tbm kernel
In dual core mode at a maximum clock of 1728 MHz and minimum of 214 with -100mv of UV I had 16 hours of battery time. 4 hours of screen time with normal use, music, gps, chrome and what's app.
The usability its better than stock kernel.
I never had lag issues or bugs.
My best and only at the moment is CM 10.1 + Franco Kernel.
On 2G, wifi on, auto brightness , I've been getting 40 minutes of screen (browsing, on Facebook, etc) at each 10 percent of battery.

For me, I quite enjoy Trinity/Franco/Community Kernel with Carbon, or Trinity and CodeFireX. Both super-high performance ROMs.

Also, I thought that "best of" threads weren't allowed.
I use latest PA and franco.
Hello. I'm on stock 4.2.2 and enhanced stock faux kernel. Stock is fast and pretty stable in this combination. I want try something different but when I try CM with faux kernel it become unstable. Why I'm using faux kernel? Because I'm using Trickster Mod. Which ROM working good with faux kernels? PA maybe?

i think it's ok. It doesn't evaluate best rom's or kernel's. It evaluate experiences. but if it's not ok - i can change thread title. Thank for the hint :good:
Guys, can you please add the section? Nobody knows for which goal is your combination good! Thanks in advance!
Stock + Franco Nightly
I want a flawless system so I stay on stock Android + I don't have the time to maintain nightly updated ROMs like CM, although I really like CM, especially its free customization... But doing those customization = Eat up my time for studying... So I decide to keep me and my N4 away from them
However I cannot accept the battery life and CPU management of the stock kernel so I chose Franco Kernel. I nearly do not play games and I accept seldom lags. My main use is browsing the web (often open up to 10 tabs ) and texting. My battery usually lasts for one day with ~5 hours of on-screen time and it's satisfying.
Running Carbon 1.7 with the latest Trinity kernel (131). Looks pretty solid so far.
Stock + Motley's kernel, with 2.5 days uptime + 3 hours SOT. Can't complain there.
Carbon 1.7, Franco latest nightlie using the BeastlyBattery power mode. On average 5hours screen on time.

Have you tried the current custom kernels?
I am using SpeedMod 3-9 and it has an excellent battery life - on heavy usage (internet, emails, ebook reading, messaging and phone calls) I reach the end of the day with at least 30% left - and I am talking about heavy use - around 4-5 hours.
For me this is more than enough.
But I am using "ondemand" CPU governor. If I change to "powersave" the battery consumption will be even lower, I think.
My suggestion to you - give it a try - our beloved Note is one of the best in battery tests - and with these tricks it is even better!

You even can reduce power by using a single collar wallpaper.
For black take a picture in bl&white in the lowest resolution with the lens covered with your finger.
You can select this picture as background.
If you like an other single collar you can do it with a paper of your choice

really ? i'm using that for one day, with heavy use of emails, texts, and watching CCTV in my office with 3G always + wifi = end up 10% in 6 P.M from 7 A.M. and one more thing, i love live wallpapers, so i use Koi wallpaper, and auto brightness.. i thought that with 2500 MAh battery it would last more than 1 days of heavy use... you know, i seldom use that in my house, but very heavy user in the office, no games.
bump, how about this http://forum.xda-developers.com/showthread.php?t=1257497 ? more kernels = more choices for users
there is already a ton of custom kernels for the note, Surely you havent tested them all ?
99% of battery drain is down to the user ! anyone will confirm this, You should look a bit deeper into your configuration.
start from a full wipe, test several kernels and try all of the Governors & Schedulers, Use something like 'better battery stats' for precise information of which apps use most power, fiddle with settings like auto-sync, wifi off when sleeping, data network deactivated when not in use ect ect.
1 day battery life is about the average for the average user, This is a powerful device with a massive screen and 2 CPU's, you cant expect the stock battery to last forever, Maybe consider an extended battery ?

For the usage you described, it seems that no modern smarphone would handle it - maybe the Moto Maxx, with its huge battery - but it is not in the league of the Galaxy Note.
But, instead of going to an extended battery solution, which would make your Note heavy and thick, you could go for a "spare battery" solution. And you can find plenty of good quality batteries+charger for less than $20 on Ebay - this should solve your problems entirelly.

Well you have said it all and given your own answer in your post - you are a heavy user and there are no scripts on xda that will give you additional battery unless you bring 2 or 3 stock batteries with you.
Extended battery is a bit too big in my opinion and will make the Note really too bulky, but if you don't mind the size this is definitely the way to go to have more juice by the end of the day.
[GUIDE] *19/8 UPDATE!* 4.3 RESULTS! N7 'Best' Kernel (Performance & Battery Tests)
A lot of people have been posting in these forums, "Which kernel is the best"?
I was intrigued and decided to work this out for myself and share it with the rest of the community.
This is not meant to hurt the makers of these kernels.
But FIRST, it is not a fact that there is a 'best' kernel. 'Best' is an opinion and everyone has a different opinion.
On the Nexus 7, I personally believe there is no 'bad' kernel and none of these kernels I have tested perform badly or lag heaps.
People still like to push their N7's as hard as they can though.
The Main 2 Features people look for in a kernel are:
Performance & Battery Life
Some people prefer performance over Battery, or vice versa, or an all-round kernel.

I am testing several kernels here. The fastest for me so far is trinity, but the battery is draining really fast. I then tried the 1400 MHz trinity and things got a little better with a good performance in quadrant.
I am testing motley now and seems good but a little slower than trinity. Home screen doesn't look as buttery as in trinity. I will keep testing a little longer.

Crap...i just had a reboot while using motley and started playing dead trigger. I returned to trinity 111 and it is definitely smoother than the others for me. Maybe it is because it is the first one i flashed and now when i try others, even wiping, something remains and the other kernels don't work right. Who knows....

I posted about the so called battery life screen shot thread in there thread.
the only way to really test battery life is to start with ful ly charged battery each day. 1 TEST PER DAY or charge cycle.
you will have to get a mathematical equation figured out first .it would have to be something like
cpu cycles x screen brightness x memory usage and s on divided by then another equation to determined battery pull watts im guessing
you would have to keep the first exact on each test device to determine the battery life ..
ok while typing this i have decided its way over my head and quite honestly not sure it can be done ..
HELP My brain now hurts ..
The best way to test CPU performance would be to make sure that all kernels are at the same exact core frequency max, and all cores enabled, on performance governor. Performance governor alone doesn't enable all cores, and benchmarks sometimes don't trigger all 4 cores as on either (it can, but not always, and that can lead to totally different numbers on different kernels).
Some kernels have higher max frequencies then others, some use the new CPU quiet driver and some don't (although this wouldn't really matter if all cores are forced on for testing).
Some kernels have higher GPU clocks then others, some have higher refresh rates then others, some have both higher refresh rates and clocks, etc.
Personally, the best way to judge a kernel is by what features are implemented in it for example, is it linaro compiled? Does it use the old hotplug method for CPU cores, or the new quiet driver? Updated WiFi driver? fsync toggle? Was it built with RNDIS drivers?
Quadrant isn't a stable means of benchmarking (run it 3 times in a row and watch those numbers change), but generally speaking, if the same kernel is compiled with linaro, vs no linaro, the linaro build would be faster (don't quote me on this). Not all those kernels are linaro that I'm aware of.
Also, Jay's buttery smooth tweaks, his fsync doesn't work on franco.Kernel. That kernel specifically uses a different command to toggle fsync, and unless that method was used, any I/O results would be void (basically comparing fsync kernels to non-fsync, where fsync would obviously dominate). And there is even the possibility the ROM you were using may interfere with CPU clocks and voltages unknowingly.
So with all that said, trying to find the "best" kernel, is going to take a bit more effort then just benching with Quadrant
And for my own personal opinion (no hard-testing done) I like franco.Kernel Stock clocks and voltage, fsync toggle, new CPU quiet driver and WiFi driver, works awesomely faux's kernel would be my second preferred kernel, only because lack of fsync control, and getting rid of the CPU quiet driver.

Used Motleys 520 at first, probably still my favorite. Used trinity and both of clemsyns latest. Clemsyns elite 1.8 got too hot for my liking, I'm using the 1.5 UV right now and batteries not too great, but its very smooth. Trinity is smooth as well but Motleys 520 seemed to both perform better and give better battery life at comparable clock speeds to the rest.
So Motleys will be my daily, but I refuse to stop flashing!
this is very helpfully
thanx

You can't tell which is best if they are not under the same circumstances. Obviously Franco is top because his only goes to 1.3 which is stock. While others are over clocked... thats unreliable.

Yeah. I guess... I was going to try Motley at 1.3 for fun anyway. See how I do...
I decide after using franco's kernel for a long time..i think this is the only one i used ever since i buy my nexus.
So i decide to try other kernels too cause roms are the same minor differences so after using faux123 kernel for 1.5 day, i saw a great battery life compared to franco's, but i have to say that with franco's i used my phone alot and flashing all kind of stuff.
So i decide to at least give you an example of how kernels do with battery lifes.
So i used antutu tester that have a battery benchmark and give the kernels a try!
*REMEMBER THIS IS JUST A BENCHMARK, YOU HAVE TO USE THE KERNELS WITH NORMAL USE TO SEE THE TRUE USAGE OF THEM*
I started with faux cause i already had it in my phone so i give it a try...
1) Faux 015m took 1H and 42m to go from 100% to 18% The drain per hour -26.1% and average Temp 44.6C
2) Franco 147n took 1H and 50m to go from 100% to 19% The drain per hour -25.3% and average Temp 41.0C
3) Trinity TF131 took 1H and 35m to go from 100% to 19% The drain per hour -28.1% and average Temp 41.0C
Its a long an borring procedure thats why from last night till today i have only test those too kernels...i will test also trinity, airkernel and semaphone
Also im not so good with excel there are years passed that i haven't touched it so i wasn't be able to find the drain per hour formula in excel!
I hope i found it!! ^_^! Correct anything you found wrong in the spreadsheet!!!
Nexus 4 Kernel Benchmarks Spreadsheet
Thanks and i hope that you may find it usefull!!
*INFO*
For this test i use AnTuTu Tester. Im not changing anything on kernels except the Volts, im UV -100mA on every kernel.
For ROM im using the latest PA 2/6 3.60 with all my apps installed (140+/- apps) with full brightness (default when benchmark starts) wifi open and 2G network with data off!
All background apps closed and no other procceses happent on the time the benchmark runs!
My only concern is that at least for now both faux and franco's kernel have the same results the differences are minor!So maybe all kernels work the same with the same power usage or antutu tester isn't the best realible application...we will know when i finish testing all kernels!
Very useful, we could add matrix kernel to the test It is interesting to see which one has better battery life.

I saw matrix but i think its in a state of abandonment so thats why i didn't include this and motley too!!!
Matrix kernel is not abandoned, on the contrary tomorrow is going to be 9.0 version released.
matrix kernel isnt abandoned! Version 9 is due soonish!
Look forward to reading more results .

Cant wait for the results :victory:
very goog idea please include the other kernels like matr1x and trinity and so on. keep up good work! many things depend on mobile configuration but it gives a little view. thanks!
Just finish the trinity test...here are the results..update the OT and Spreadsheet!!
3) Trinity TF131 took 1H and 35m to go from 100% to 19% The average drain was 59.5% and it have drain per hour -28.1% and average Temp 41.0C
There is a thread in place here, use it...thanks.
Hello World! What's your current ROM and kernel you're running on, and what do you normally get for screen on time? I'd like to get some suggestions.. Would like to get through a whole day comfortably
It doesn't really matter how much screen on time someone else gets, it doesn't mean you'll ever achieve that same amount. Screen uses a pretty constant amount of power per brightness setting, but the other things that use power will take away from that and not all those things are to do with CPU usage, which is the only thing a ROM/Kernel can affect.
On top of which:
"Best" ROM.
There is no such thing as a best ROM. The question itself is ambiguous. "Best" is obviously a subjective term.
What I want from a ROM may well differ from what you want from a ROM, ergo - what is best for me could be worst for you.
If you are asking what the most popular ROMs are, or which ROMs people are using, you can see which threads stay around on the first few pages (and have the most posts) in the Android Development or Original Android Development forums. You can also see what other people are running by reading the What are you running on your Nexus 5 thread.
If you are asking which is the most stable, being a Nexus device - they're all pretty stable.
If you are asking which is best on Battery, ROMs only affect battery if they have a feature that is badly coded. You will likely be able to read about this in the ROM threads. ROMs do not impact battery life. The only impact to battery life are your apps, your settings, how you use the phone and mostly, environmental issues such as Phone Signal.
For tips about improving battery life, please read [Battery Life Help] Troubleshoot battery issues here!
"Best" Kernel
There is no such thing as the "Best" kernel. What we all want from a kernel is different. Again, many people have the misconception that Kernels affect battery life. Let's get this cleared up. Although Kernel devs will build in optimisations and efficiencies that will improve battery life, these are very, VERY tiny...and if 1 kernel has these optimisations, they likely all have.
People will often say "Kernel x is better than kernel y for battery life". This is actually wrong. Kernels respond to user settings. Setting up the governor to favour either battery life or performance is simple enough to do, you just have to do some learning. The reason people think Kernel x is better than y is because developers set their kernels up with their preferred governor settings. This is what we refer to as out-of-the-box settings. The out-of-the-box settings for kernel x may well produce better battery results than the out-of-the-box settings for kernel y, which favour performance. The fact is, you as the user have the ability to tune kernel x or y to perform the same, be that battery or performance - so start learning how to do this yourselves - that way, you can choose the kernel based on the FEATURES you want, and not the fictional performance benefits of one kernel over another.
Hope this helps

Yup that does help... No such thing as 'best'. I didn't make the best title lol.. Currently happy with SlimLP and Franco, just wondering what you guys were getting . What are you on, as of now in terms of ROM/Kernel?

I hate the "it all depends on your phone, each one is different" bullcrap. That may be true to an extent, but some combos are generally going to be better than others. Besides, most people who ask this question just want to know what people are using and what is working for these people. So now that my rant is over, I'm using BrokenOS with Sensei Kernel R52. I'm getting roughly 4-5 hour SOT with roughly 50-60% brightness and 18 hours off the charger. I'm using the blacked out gapps that are linked with BrokenOS and using the black Swiftkey keyboard theme. All of the black saves battery when the screen is on because those pixels are off when using amoled screens. Don't know if you know that or not, but hey, it's there. Also, I've set the kernel minimum frequency to 223mhz using intelliplug with fsync and mpdecision off using the trickstermod app. I've set the scheduler to fiops and changed the read ahead value to 1024. This has consistently given me these results which I consider to be great! Hope that helps!

That helps greatly! Yes, this question was more of a 'Which ROM/Kernel is the best for you' type of question. And yup, I do know that AMOLEDs give you those pitch black blacks, which is good for battery, since those pixels aren't being used. I myself, am a big flashaholic, tried at least 5-6 Roms and a bunch of kernels.. Best battery life so far for me seems to be Slim + Franco.. Never tried BrokenOS, will flash tonight Thx a lot for your detailed response :good:

Each phone is different but that really has nothing to do with battery life, except that maybe some CPU's can undervolt more. I'm not sure anyone has given this "bullcrap" answer you eluded to.

Check out my rom chroma. Franco kernel is preloaded. Huge update coming very soon.

I've tried most of the roms and kernels and have always gone back to BlissPop and either Lean or Francos. BlissPop for the features and Lean/Franco for the battery life. I would consider myself a moderate to heavy user and get between 4 - 5 hours of sot, but more important to me, I start my day at 5am and shutdown around 10:30 - 11:00 pm and I generally have 35% - 40% or so left. Of course your milage may vary, I also greenify what I can, but I refuse to lose any features i use, why have a fantastic phone and cripple it. I generally don't change any of the kernels, except maybe set it to conservative, I've had issues in the past undervolting, but thats just me. For the slight battery savings I don't find it does that much. Again, my opinion.
Just take a nandroid of where you are and try some combinations. Give it a few days to settle in. Repeat until your happy with the combination.

Will most definitely flash Chroma... Looks like one of the best designed ROMs.. Will flash it either tonight or tomorrow morning... And your name seems familiar from the numerous pages I've went through on Franco's Kernel lol. Thx :laugh:
how many hour is stay on the stock ROM ?
Chroma with FK and vomer are poetry in motion. Use it and prosper.
using the rom that i use, and kernel, and the way i set up my cpu, i see between 5.5 and 7 hours sot. which rom and kernel? try them all out, find your best rom/kernel.

I am on Terminus currently with Franco Kernel undervolted all frequencies @-50 which is 100% stable in my case. -75 crashes on games and/or benchmarks. My Snapdragon has a PVS 5 binning.

Hiii Guys I'm Currently Using Blisspop V2.2 It Was An Awsome ROM Except Its Battery Performance, Since The Xiaomi Released Kernel Sources i've been observing xda mi3 section there are alot of custum kernels thanx to all devs,and i did not try any one so far, so my question is especially by considering Blisspop rom is there any best kernel which improves the battery performance in mi3?? please suggest me and help mee waiting for ur valuble suggestions..!!
Thanku in advanced..!!
Stuxnet+ it is!

I'm using the Stuxnet kernel too - though your question is impossible to answer. It really depends on your use, combined with the governor/min-max processor speeds etc. Most of the kernel variables are accessible for all custom kernels.
Also, what is battery performance? Days on standby, or hours of screen'on time? Browsing or gaming..?
It's very easy to limit battery consumption by reducing screen brightness, running a conservative governor, not using the upper available frequencies etc.
I'd say that they make a bigger difference than swapping between stable kernels.

here in my view battery performance means Screen On Time..!!!
A search would have answered this. There is no best. Try them each out for yourself.
