[Q] Battery efficient rom+kernel?

hi
sorry for being such a nooby mcnooby-pants
but i just want to know which combination of roms and kernels will give me a great battery life and at the same time i want to be able to overclock to 1.5 GHz
i looked through the forums and i did all the basic stuff like
undervolting
setting profiles in setcpu
and removing all the bloatware from the phone
but everyone has a different combination and im really confused as to which combination to use
right now im using eaglesblood 2.3.7 with the dragon kernel and its really not working very well
so any and all help will be appreciated
thank you

My opinion:
1. Jump on a stock-based ROM with stock kernel and UC (underclock to 900-800 Mhz, you would be surprised you notice very little change in performance). Most stock-based ROM users report back great battery life.
2. Jump on a CM7 Nightly 199 or higher (Reports of great battery life, I can attest to this) with morfic or faux123's kernel (I prefer morfic's) which you can undervolt easily with Pimp My CPU (search XDA). I prefer it to SetCPU because the only profile I use is UC when the screen is off and with Tegra's DVFS CPU governor, it already does a good job of doing this. I also UC with this setup.
Delete Wi-Fi Calling (Kineto.apk) from your phone if you're not using it. I learned this from lotherius, it's always running in the background even when off and not in use. I was shocked to see the improvement.
I know it sounds stupid, but if you're in class or at work and don't need a barrage of updates on your phone, just turn off data. Most ROMs have a quick toggle setting to efficiently turn it on and off quickly and you'll be quite happy with how long it lasts. If you have to have data on or think it's moronic to have an Android phone that's not does not always have a data connection, battery drain is just the price that is payed.

woah.
Awesome answer
so do you think option 1 is better or 2?
does using cm decrease the battery efficiency?
if it does do you think the extra functionality in cm makes up for the batteryloss?
Thanks btw

Try miui 1.11.4 from whitehawkx with faux kernel cm-4.4

Good question, and I think that is totally up to you.
For example, my father and I both own G2x's, he runs a modified stock ROM (xboarder's ROM) and I run CM7. Without a doubt he gets better battery life than me, but at the cost of not having the features I have.
That may be a rough way of putting it but yes, using CM7 with all it's awesome features come with the price of not being as battery efficient.
The real question is if being less "battery efficient" actually means it's a bad thing. In my case it doesn't matter to me at all. Using the quick panel toggles in CM7, I only turn on data when I need it and I easily pull 15+ hours a charge because of it, assuming moderate usage.

Consider lotherius's tsugi rom, currently in version beta 3. It is my daily driver, stable, faster than 2.3.3 based roms, and excellent battery life. He has included a 2G toggle app that can automatically switch to 2g radio when screen is off to save lots of juice.

[Q] stock rom vs custom rom

good morning,
i'm quite new on this phone even if It works fine for me with a stock rom 4.0.4 I would you like to understand if there is a good advantage to pass on a custom rom.
Please share with me your experience and answer with my few questions:
what kind of custom rom and kermel you have on?
which is the difference there is in term of battery life; performance; stability.
Thanks for your help

Welcome to the Nexus ... you're going to love this phone. With that said, you need to jump in and do some reading. There is no shortage of opinion on which rom, kernel, or even GB vs ICS ... is best. It very much depends on your likes, dislikes, etc. I assume that you have a gsm device, so make sure to flash the appropriate roms, kernels, etc. Lastly, there is lots of help available, but it's always best if you dig in and bring yourself up to speed with what's already been posted in these great forums. Good luck!

thanks mate,
after few weeks i tested it, i find this phone a very good one and I don't feel the need to jump in a custom rom. I rooted it, installed a busybox and the clockwork and I added some apps to eliminate some gaps like the missing notification when the screen is off (I installed the noled apk for it) or like a switch off or switch on of the screen using the power button (I used an apps called accendi scermo and I switch on and off the screen using the phone sensor). The only thing that miss on this phone is an fm radio offline. I'm still searching a solution.

Stock rom: more stable, less features
Custom rom: less stable, more features

Well if you want to be normal. Than good for you.
Now a custom rom and kernel can give you unlimited privilages to things you can never imagine possible. Undervolting your device to give you brain blowing battery life or over clocking to give you awesome graphics.
A custom rom like CM9 or AOKP (there are way more than two but im just listing the popular ones) is of course better than stock since... well if it wasnt why would they make it. A kernel links your hardware to your software, meaning you can do some tweaking in the middle. If you find the right kernel and rom mix you can have a wopping 15 days standby on your battery (eg CM9 and Matr1x Kernel).
Now thats just the basics. if you are interested and want more information. Just do a bit of research and reading in this forum and ask questions in those forums. Hope this helps.

ics 4.0.4 stock+ simple or thalamus kernel

Or Bugless Beast with one of those kernels

How fast are custom roms on the GS3?

IMO the stock phone is extremely fast and smooth. With 2GB ram I also haven't seen any apps being forced out of memory.
So with a custom rom, all the speed tweaks etc, what exactly is improved over the stock phone. Do apps launch faster, less lag etc? Are there any videos comparing stock vs custom (esp AOSP vs TW) ?

I personally just used AOSP for about a day, switched back due to a few bugs, but it was definitely speedy quick. Faster than stock? Yes for sure, but stock is super fast as it is. As for AOSP vs TW, i'd love to stay on AOSP but i love the TW camera and just can't get over not having it You should try custom roms for each one and just see what you prefer

If you look on YouTube you will find several reviews on roms currently available for our gs3.

At this point in time they offer no advantage over stock. Hopefully one day they will but Samsung did such a great job on the stock Rom for a change that our custom roms are a little faster but with a few things broke or bad battery life or bad 3g/4g hand off.

I agree 100%.
I have tried every ROM available at this point & I always end up going back to the setup in my sig.
I always chuckle when I read post claiming a ROM is smoother/faster/less lag etc than a completely debloated stock ROM like CleanROM or Synergy. Talk about the ultimate placebo affect......

Most have issues but many offer huge advantages from deep functionality to deep customization. If those interest you, perhaps small issues in stability or data usage are a worthwhile tradeoff. Not to mention that the simple fact that you CAN do such a thing is a very fun and educational experience about what is special with android.
Also, debloated, over clocked TouchWiz Roms like CleanRom are faster and able to be set up for greater battery savings. Without question. It's a large field! Have fun by doing, you can always go back without cost!

The title of the thread was "...how fast..." I've posted on this before. Can we humans detect the subtle differences? Are the new roms simply a placebo effect of speed? I don't know.
What I look to are facts. The only facts we can use in comparing roms are the benchmarking tools. I have tried many different roms...Incu's, Slim's, Synergy's, Phantom, etc.....I have recently been flashing the Incubus Jellywiz roms pretty regularly, but got frustrated with some of the bugs ( more on these later ). So I went and retried the latest Slim and Synergy.
I can say. There was a perceptable difference between Slim/Synergy vs. Jellywiz. So I did a benchmark test. I tested each rom under pretty much the same conditions.
1. Flash the latest.
2. Disable the same Allshare/Samsung crap.
3. Load all my apps using Titanium.
4. Let the Rom settle for a most of the day
5. Test in the evening
No Overclocking...No other special changes.
I tested Using Antutu and Quandrant Standard....Slim and Synergy were about the same...in the high 4k's...around 4800 Antutu. Incubus' Jellywiz is always around 7800. Slim/Synergy was around 4800 in Quadrant, Jellywiz is consistantly up near 6000.
There are trade-offs / bugs / features....but...if you're looking for speed, I don't think you can find anything faster that Jellywiz.
The latest Custom has a custom overclocking kernal....for fun I bumped it up to 1800mhz and ran a 9500 Antutu. right now I'm running 192min 1200max and still pull a 7200 antutu score.
You pick:
> Speed = Jellywiz
< Bugs = Custom stock
My $0.02

CleanRom 2.1 with the CleanKernel 1.2 runs excellent for me, no problems, definitely quicker than stock, very smooth.

Andromadus vs. Jellytime vs. PACman vs. Pure CM10

Hello,
at the moment i am using Jellytime. For now i am happy with this, but i think the battery life could be just better. So which rom from above offers you the best battery lifetime?

im using pacman.. the battery life is good.. i can use the phone the whole day(surfing, internet, texting, music...).. i always plug my phone in before going to bed, and i still have around 10% left

Me too. Battery life is very short using Pacman v18.0, at most 5 hours. The screen is the process that consumes more battery. Maybe it is only a my problem, but with Fallout v.5 I didn't have this problem (but others :laugh.

Well I find the battery life good on pure CM10.
If it wasnt for the graphics glitches when browsing, it'd be a really good ROM!

I have installed Pacman v18.0 about 3 days ago and am very impressed with the ROM. No problem with battery life but one major problem with the phone randomly going into Sim Lock mode. Could be after 5 minutes, could be after 5 hours and sometimes while just using it.

PACman, way to go.

I'm using Andromadus CM10.1 and battery is good...Overall is good except Bluetooth that doesn't work yet...

Mine has about an hours worth of battery...
For now I'm switching to my sense rom

On the latest build (build 10) of Andromadus 10.1 I found that the bluetooth was fixed!
Overall, at this time, I believe that the 3 andromadus ROMs are by far the best Jellybean effords!

Thank GOD I got here...
Could someone help me with rom that includes these features?
1. The official ics look (nexus ics)
2. That includes all apps like the sensed ics got. (fM radio,voice recorder,youtube etc)
3. My wifi doesnt turn on when i use any custom rom It just says "Turning on wifi" for the whole day.
4. The settings tab normal (not the tablet type like pacman got)
....
Thanks

some people prefer to UV their kernels. Some people don't prefer. Some kernels allow UV, some don't. see it all comes down to preference,of course UV also may cause performance to decrease. so it stills come down to preference.

Hmm, when ppl say try it yourself, it simply means that u would have to flash the rom to know what's best for u.
Everyone uses his/her phone differently, so basicly there is no ideal rom that pleases everyone.
Everyone will you give a different opinion in terms of battery/speed/etc. That's why it is a bit pointless in asking what's the "best rom" for the other person when the usage is different.
So no point having second doubt and just flash the phone, try every single rom, i have flash from sense to cm to ics and now back to gb.
Go ahead and experiment the roms for yourself. Today someone might give u a suggestion, the next day a another. that's why it is consider pointless in asking such question as 'which is the best can u recommend me' and much better to try it for yourself instead of being shortchange in case there is another better than that is being suggested.

Camera Issue
Does any one facing camera issue?

Fastest 4.4 KK rom?

Hey guys I just recently got a second hand Ns Im using as an Mp3 player for the gym I loaded ENHDROIX rom but its prettty laggy and stuttery. Loading Pandora is extremely sluggish and actually crashes a bit.
Im looking for a rom with some decent speed and just a few perks, volume rocker wake mainly.
Thanks

well I placed the issue of Pandora in there so perhaps someone who uses the phone the same way could input on what they use and that its comparable to what I am looking for.
I would just dump rom after rom until I find something but time for me is super precious these next couple months.
A chart is great but remember Im not using a lot of the features the charts will describe.
Im only using it for google voice (to see my calls in the gym), pandora, play store, and play music, then some web browsing of course.
I actually turned off all the phone and data features to hopefully conserve battery life.

I just read it. I can try the slim rom. Im going to try installing devil kernel later first and see if it helps.
Still just hoping someone who is utilizing the same features I am can drop in and give their input. Not saying any rom is bad or better just looking to save some time, Im on the road a lot the next few months and the gym is my only real down time. Last night it was quite frustrating dealing with pandora.

The rom version you are using is partly to blame, newer isn't always better, go back to a previous version and install Devil.. the same for Slim, I wouldn't suggest passing 3.0 as of right now and Illusion has a couple issues, but it has serious speed...

Euroskank KitKang is another good option, and Devil Kernel is a must for any of the CM based ROMs, in my opinion.

Try Illusion 3/16 ( I made a bootable version, as the original had a flaw in the updater script, link is on the page) and flash the boot.img from your AOSP rom.. I was getting 5500's in antutu on stock speeds and 6500's overclocked, smooth scrolling and better battery life as well...
Don't try Devil with this rom as it breaks the playstore..

I haven't tested Cyanfox since 2.02, it is a quick rom.. the site is down, gearing up for version 3, I wonder if our device will still be supported?.. C-rom is very fast with Devil kernel, (the initial release, the second release is slightly slower than the first) and has tested higher than any rom I've tried to date, even higher than when I tested Cyanfox.. If our device is supported in version 3, I hope the rotation bug is fixed..
