Best ROM for battery life? - Nexus 7 General

I am wondering if some ROMs perform better than others in terms of battery life. If you've noticed differences in battery life between ROMs, can you please let me know? I am currently on the latest PA nightly, using M-Kernel 37. Cheers!

I run PA 3.0 and Faux Ultimate Kernel.. but I have it underclocked to 1ghz. I get great battery life out of this thing. Been 11 hours since I left the house, moderate use (nothing too heavy like games, just social media really) and I'm at 90%.

"best" rom threads are not allowed on XDA for various reasons including the simple fact that there is no such thing as a "best rom". Its all opinionated and subjective. What is "best" for one person will not be "best" for somebody else.
The best way to find the "best" rom for you is to try them out and find out.

As said Above, Thread closed for obvious reasons.

[Q] ROM for best battery life?

Edit: go ahead and move me, wrong forum...
What is the ROM that you guys have experienced the best battery life on? I had great battery life on one of the Cognition betas right after DG started using Froyo, but I don't know which one .
I'm using Perception Build 7 and I get a strong full day of use, but I would love to get more. I usually keep certain battery-draining activities to a minimum (e.g. auto-updating apps) so I would like to see even better performance, battery-wise.
So what's your experience with battery life and different ROMs?
Any of the latest cognition roms were best for me. I find that the ported roms are never quite as good.. but im using them anyway for the speed.
I found the insanity rom with the cogkernel was a pretty good combo. The rom was minimal and the kernel was just uv and not oc. It was pretty good. It rivaled the battery I got with frankentwiz and the unhelpful uv combo,Which ill miss forever T.T

i find the assonance ROMS have decent battery life
Axura with setiron 1.4.3. Tried with dgkernel and causes sleep death. Perception yields good life also

I just flashed 4.3, going to see how it does!

Captivate rom help....battery and performance.

What is the sleekest rom that is farely fast in quadrant yet the battery life (combined with a modem and kernel) is dependable for light to medium use? Im currently on pheonix ultimate. Not only is it fairly slow but the battery life is not the best even when screen is off and wiring and data are off.
Sorry if it has been asked before. I prefer a gingerbread based captivate rom but anything 2.2 or over is suffice. Maybe explain too what a good modem and kernel are that don't necessarily oc or uv but can...that don't drain battery!
Much Appreciated,
Your Noob.

Haha... Wait for it...
Not sure what the answer to your question is, but this hardly belongs in the Dev section. Q&A would probably be best. I have already sent request for this to be moved. Oh well... hope you get an answer after it's in the right section.

Quadrant means nothing. Dude

It's hard to say which ROM is the *best*, you just have to give them all a shot and see which works best for yourself. Battery wise, doesn't only depend on the ROM itself but also if your battery is old, you might consider changing it.
I don't think quadrant matter either, just numbers, as long as the phone is smooth when I use it, it's fine with me.
Quadrant doesn't mean a thing, but I have found that kh3 roms have the best battery life.
Currently Pinnacle 1.2 and have never been happier
fusion v is fenomenal. fasty is great too, if you can deal with the obtrusive theme and animations
Why don't you just try flashing some roms and see what best suits you instead of asking a community to publicity place a value judgement on other developers hard work?
And for your edification, this is the type of question for.... you guessed it.... q&a, not development.

No rom is the best. But my experience Native roms tend to run smoother for longer periods of time, and 2.3.4 KH3 roms have the best battery life. Dont ask for "best" because there is no best you gain some things and loose other. So try them out.

Best rom for battery life?

Hello, I am currently using MIUI but it sucks for battery life. I want to flash a stable rom with long battery life, and nevr to forget about flashing (because I will sell my phone to a friend of mine very soon and he is noob in all of this things like roms). What would you recommend?
Sent from my I897 using XDA App
I had amazing battery life with Pinnacle. 24+ hr easily with medium-heavy usage (very subjective, but 100x better than MIUI, CM7)
I flashed serendipity 6.4 on my mother in laws phone in july and I have yet to have to do anything with it except the things she messes up, like losing the app drawer icon. I also ran the rom on my phone and it had great battery life.
Sent from my SPH-D710 using XDA App
Generally speaking native roms offer the best battery life over all (KH3, KI#, KJ#,KK#, etc). But like mentioned before very subjective. This thread will probably be closed due to the nature of it.
If you are giving it to a friend that is not into roms. Stock is your best bet. Don't want them to have to deal with the issues of a custom rom. Like drivers and app compatibility issues in AOSP roms like CM and roms like MIUI.

[Q] Overclock kernel with best battery life?

I've used Faux123's kernel for awhile, has anyone used both and if so which has the best battery life?
faux123's still has the best battery life and speed in my opinion. I've been using it since the first release, and my battery life can last up to three days with heavy usage while using the kernel, I even had it overclocked to 1.7 GHz.
Also, we now have a Q&A section, please remember to post your question in the appropriate section next time.
wow!
3 Days is a miracle from my experiences, I believe this is with light use! I must admit I find myself curious to try it!
i have general and development bookmarked so I didn't even know there was a question section, thanks though!
No problem, I hope you have come to a conclusion to which kernel works best for you.
Faux's kernel is still my favorite, i feel like kozmik's has too much extra stuff like sleep to wake, im sure that isn't great on the battery life.

It has negligible impact on battery. All it does essentially is imitate the power button to unlock.
Personally if I felt that battery life was the moat important thing about a phone then I would just buy an non smart flipphone

[Q] Best ROM/Kernel combination for battery life?

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.

"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.
