[Q] Best ROM + Kernel combination for battery life? - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

Pretty much what the title says.
Preferably, I'd like to stick with Touchwiz because I like it, but if the TW UI bogs it down then I don't mind suggestions for of other ROMs. All I really care about is battery life (and maybe performance when I run heavy games from Gameloft, for example.)

To be able to get accurate results you will just have to try them out to see for yourself. It kind of sucks. But its just a reality. Our devices perform so much differently from each other when it comes to kernels that one might be able to run ktoonsez's kernel but the next guy can't. It a sad thing that all devices are not created equally. Same thing goes for ROMs. Probably not the answer you're looking for. But its just a fact.

[Q] Custom ROM vs Stock ROM - is it really that much faster?

I bought my GSII used, already rooted, with a custom ROM already loaded on it.
I have to ask - since I never used one with a 100% pure stock ROM - is it really THAT MUCH faster with a custom?
I am currently running Juggs 5.0 - but if I went back to 100% stock would I feel that much difference?

It's not really about speed. But with a custom ROM you definitely have more customizations possible. You can change the look of the interface, the notification toggles, colors etc. I have the i9100, which is another variant of the SGS2 and I've had ICS for a couple of months now, but it's not getting officially released until this month some time. So, it's not really about speed but rather about the freedom to do other things with it. Some people might cite benchmark tests, and scream that I'm wrong, but the hardware is what makes your phone fast...the software's not at all going to choke that out (whether stock or custom). As far as speed goes, you're probably not going to notice the difference.
Also, though you've got root access which enables you to install apps and do things you just can't do otherwise.
All that said, there are certain advantages to stock. It's often times more stable than something custom. There are ups and downs. If you feel the need to experiment, you can always flash back. Just read a lot before you get your feet wet (it is very possible to brick your device if you muck it up) and you'll be fine.
I don't think so. I'm going to get flamed plenty I'm sure but I don't see much improvement over how my phone performed out of the box. I think the battery life may even have been better before I started flashing stuff.
I should have stated in my original post - I am definitely not a n00b to Android or to flashing/rooting. I can understand the customization aspect, but honestly other than flashing, I have never had a real use for Root access.
I can flash something with a new custom interface or colors and always end up coming back to something that has the stock look about it... In this case, I've tried almost every available custom ROM and keep coming back to Juggs .
I ask about speed though because all the ROM cooks seem to try to use that as a selling point... "FAST!" "Butter smooth!" blah blah blah ...

After I posted, I looked at your tag, and assumed as much with 700+ posts, you've been around the XDA block.
Really? No need for root?! I'm a flashing junkie (well, okay, that's exaggerated. it comes and goes in spurts) TitaniumBackup is my friend. Also CWM is a gift.
Agreed, stock ICS is love. But I do also like certain tweaks, i.e. the %-battery indicator (and while we're on the subject, I've got a little Android logo with a % indicator for my battery...I wonder why Android devs don't include little things like that).
Yeah, your best bet is to try some out. But IMHO devs talk too much in that regard. I'll probably get flamed if any read this, but devs are kinda like used car salesmen in that regard. They've got a product that they want you to use, so they try to sell it. Can't say I blame 'em, really. But again IMO, most of it's hype.
I didn't think you were new to Android since your account is almost 4 years old so I'd assumed you were familiar with all the "benefits" of rooting. The phone is so nice out of the box I don't think any of the roms are any smoother or better on battery. I think Warfare is probably the best on battery and for me CM7 was easliy the worst. I didn't notice a change in data speed, 2d smoothness, 3d smoothness, battery cover smoothness... Nothing. The device is so nice out of the box and I don't use it for anything other than a phone, text messaging, web browsing, e-mail, Skype, the occasional slicing of fruit or a word or two with friends so I can't comment on all the added functionality all the "super-duper heavy users" of this device probably use on custom roms. The only reason mine is rooted is for an ad host file and the occasional tether.

When I had a Fascinate... I was a huge fan of overclocking and undervolting. The same when I had a Thunderbolt. It made everything smoother and the Thunderbolt especially needed help in the battery area. This device just works. No need for anything other than what it came with for me. Obviously that didn't stop me from flashing the development section... But hey, I have a problem.
Warfare is very good.but,no advantage so far.
For me,im back on stock.just works better for me (doesnt mean I wont have a flash attack).

the thing with our device is that it came sooo sick straight out of the box that you don't really need to improve it that much. However, custom ROMs/kernels generally make the ROMs smoother, but not many people notice the difference.
I actually notice that because of the kernels implemented with certain ROMs, our phone is able to RUN just as smooth at a lower clockspeed which saves us battery. Other than that, I don't think Custom ROMs are actually "SMOOTHER" or faster than the stock ROM because Samsung really did well on this phone.

I'm going to look for a ROM that is close to stock as possible but rooted... try it for a week and if I can.live with the speed I'm going back to stock via Odin.

The main difference is the bloatware which really does make an impact on speed, memory consumption and overall smoothness.
Some rom cook faster, you should choose the rom cook by team have many vote on forum.

I was just going to start a similar thread actually. I have watched videos of the different ROM's that we can install on the T989 variant to get an idea of what's available and what I like. Currently SlickMOD ROM looks the smoothest with the best battery life.
Having said that, in the video that I saw, when quadrant was run on SlickMOD, while it was overclocked, the score was approx 2690. When I ran Quadrant on my Stock ROM (rooted Stock ROM without being overclocked either) I got a score of 3199. Also, after 16 hours of use I still usually have more than 50% battery life.
Other than the options for different themes and customizations and ROM control, are custom ROMs going to provide better performance and battery life than what I am already receiving with my Stock? I mean I really want to give the other ROM's a try, but the reason would be for speed and battery life and right now both are pretty good for me on Stock. Thoughts/Suggestions?

Generally speaking (I don't own this device) stock ROMs will normally get better battery life. Custom ROMs can approach stock, in this regard, but I'd be way beyond surprised if a cook made a ROM that had better battery life than Google's team of Android developers.
Problem with SlickMOD is that the dev's T989 broke and he isn't getting another one - so - development has HALTED.

Makes sense, just for fun I ran Quadrant again on my Stock Rooted ROM and got a 3358. Maybe I should reconsider switching to a different ROM for now. Stock is very stable with no real issues/concerns. thanks for the response.

Which stock-rooted ROM are you running? Mr. X's ?

It's the Stock ROM that came with my phone. I rooted the phone but haven't flashed any custom kernel's or custom ROMs on my phone. I also use Zeam Launcher as opposed to the TW Launcher by default. I have turned off animations, limited my homescreens to 3. I don't use too many widgets and I use an all black background. Also running Juice Defender to help with battery but I don't think that affects performance/speed.
Model Number = SGH-T898D
Android Version = 2.3.5
Baseband Version = T989DTLKJ3
Kernel Version = 2.6.35.11
Build Number = GINGERBREAD.TLKJ3
I don't know if that helps or answers your question. Hope that helps.
I'm willing to bet that the performance gains that are being seen on the Stock ROMs is due to the fact that they are ODEXed. By DeODEXing the ROMs can be customized to the cook's heart's content, but there is a mild performance hit taken.

My thoughts on most roms (GSM) (personal opinion)

Hi all.
I have started this thread for all users. And mainly newbies.
Now when i say newbies i dont mean anything bad, in a way i mran people eho are new to the nexus and are overwhelmed by all these great roms and devs. (Max respect to all you great devs)
If you are hoping that i will say....this rom is the best......or that rom is the best, you will not find that here...
I am what they would say a "crack flasher" and have flash most of the gsm roms (not all, so devs if i dont mention your rom its because ive had no experiance with it) anyone feel free to post there opinions.
Right lets start.
I am splitting these up in to groups.
Customization (obvious customize hell outa it...not as good battery.
Balanced. Fair customization fair battery.
Stock (ish) pretty much stock less customization. Good battery.
Stock. As close to stock as possible great battery.
I set it it out like this as its my opinion.
Right then, lets really begin this time.
From, the top.
Customization
You have aokp, liquid smooth and black ice, i repeat there may be more that i have not tried.
These 3 roms will give you as much customization as the devs can think of and cram them in there. I find that these have the worst battery. (That does not mean terrible, but just compared to others.
Balanced.
Cyanogen mod 9, eagles blood, gummy. These roms give an average user a good bit of customization and pretty good battery.
Stock (ish) only one i have experianced is bugless beast. I hate stock rom for one reason, wich is no wifi toggles etc. Bugless beast will gives me the feel of stock (wich i love) but with those features.
Toggles aren't the only feature but its what stands out to me most. Also offers great battery life.
Stock
Android revolution hd
This is a great rom for the people who want completely stock but better performance than stock.
Offers really great battery life.
There is one section i missed out as i didnt know what to call the section. The rom that belongs in this unknown section is........BAMF
i have had little experiance with this rom but my opinion is....
This is a unique rom. Well thought out. It dosent look like most of the others. Its set out diferant and offers good customization and pretty decent battery life.
And thats all, i know there are other roms i have missed out but i want to list the ones i have experianced personally.
Please no haters as i have put a lot of effort into this post.

Battery Up Times

It would be nice to have a list of how long batteries last on different rom types for different people. The premise is easy enough, but I would like to mention that I don't want to know, "What ROM is Best". Simply thought it would be nice to know what rom types have better battery life since that is the largest factor in flashing a rom (for me at least).
So, I have flashed multiple roms and have found that AOKP and AOSP have horrible battery lives on GB, but seem to last much longer on ICS and JB.
On the other hand, I see that Sense has great battery lives, but only as far as Sense 1.0.
I would also like to know why it is this way? What is it about GB, ICS, JB, AOSP, AOKP, and Sense that determines battery life.
If everyone that posts would mention what rom TYPE (eg., ICS, AOSP, AOKP, etc.) you are using, your battery life, any tweaks or mods you're using, and if you have an extended battery or not.
Hopefully this brings some clarity as to why our phones act the way they do, and how to improve battery life.
Thanks everyone.

Well.. it depends on the phone too ya know. Like guy 1 might have great batt life on gb soap and guy 2 may not.
But personally, I have great batt life with legendary 1.2. I can go about 15-18 hours with light to moderate usage
Heres a thread I started about batt life.

[Q][Gurus] Kernel + ROM. Hot picks?

For a n00b (in this context anyway!), there is a huge amount of options available.
I've pretty much decided on using the NARK kernel, but the ROM choice is a hard one. Stock Sammy, AOSP, Omega, PA etc.
While I love stock, the S-Note popup is rather handy. Although for an ultimate experience I would sacrifice it. I like minimalism, consistency, and efficiency.
NARK or otherwise, what are the current 'killer' combos for ROMs and kernels? In terms of speed, fluidity and battery life.
Any pointers from the gurus out there would be very much appreciated :¬)

Why would a so called guru respond to this.
Read up on the kernels and roms. See which have the features you require/want. Make a back up and flash.
Then you can decide for yourself instead of getting the views of people who may want something different than you.

kernel basics for a not-so-noob

okay so I have been hearing a lot about kernels lately and while I am no noob (some might disagree with this sort of question) but I would like a rock solid definition of what a KERNEL is. I understand them to be the essential backbone files of a rom. What prompted the question is that i have been reading a lot about battery life and how different kernels affect battery life etc. so how is it that the kernel actually works with the rom?
thanks so much

Heres a good link to learn about kernels
Kernel info
The best way i seen it put was, think of the kernel as the engine and the rom as the body of the car. The body of the car (rom) just makes the car look nice and user friendly. Now when we talk about the engine (kernel) simply put red lining the engine will get you to go fast but burn gas. Keeping the rev down low will make you run slower but saving lots of gas. Thats just one way to look at it, rpms being the cpu anyways.
Dont know if that helps you, thats just hoe i first understood it
Another handy link about Kernels... http://www.androidcentral.com/android-z-what-kernel
