[Q] Most stable battery efficient ROM?

I'm fixing a phone for someone. At first it was stock and crashed very often about once every 10 minutes of use, so I flashed cyanogenmod but the battery life is much worse. I just need a good stable battery efficient ROM and the other features like ICS don't matter much. Any suggestions?

Try them, and find out for yourself. Everyone seems to get different results, different preferences and different usage of the device.

The problem with that is that I'm not using the device so I can't test out several roms during the day and find out what has good battery life.

Then just leave the phone off?!? That's the best battery saving rom EVAH!

I didn't ask what's the most stable, battery efficient ROM on SGSII forum when my friend gave me a day. Flash a ROM, give it to your friend and see what he thinks of it, then if he doesn't like it then flash another ROM.
It's all about preference, you might like SCOM ROM (GB) but your friend might prefer CyanogenMod9 (ICS) more. But if your really looking towards battery life go for Gingerbread ROM.

You guys really can't just tell me what works for you or what you had experience with? I already tried to help once and it takes weeks before this person has free time to give me their phone to try and fix it again.
It's not like this phone has different hardware from all the rest of the galaxy s 4g's and they are dependent on the phone. They should all work the same so it shouldn't be such a big deal to ask for some measly suggestions.

Not everyone is going to get the same results from the same rom. It all depends on your usage.

Please state with reasons and what variables there are and what the tradeoffs are or you are talking out of your ass. Of course people's usages vary, but if you keep your usage constant while changing roms like you typically would or have a composite number than your can compare roms for battery life.
It's seriously not that hard to quantify which roms last longer on battery. This is ridiculous.

If it's that easy to you (may be?), do the testing and post the results. Document and publish your methodology so it can be peer reviewed. Please keep it up to date as ROMs are updated.
I look forward to your findings.

I just told you that gingerbread roms have great battery life.

There is no definitive answer bro. I dont get the same battery life as jeffsf or FBis251 on AOKP. And neither one of them get the same battery life. It really does depend on each phone and the users habits of use.
Im going ahead and reporting this thread because the community here dislikes these threads. They never end well and you have POHR people being belligerent .

As I've said before, usages vary but it's pretty reasonable to think that some people have used a few roms while keeping their usage constant. What makes it frustrating is that the people on this thread spew some faux wisdom that it's impossible to compare which it isn't.

I've had pretty good battery life so far with HebMIUI when it comes to ICS. Of course, GB ROMS such as Valhalla Final, Valhalla Black, and Octane are known for the excellent battery life.

All of this is far too subjective. Try them and make your own decision.

[Q] Could you recommend a good JellyBean ROM for Nexus S

I'm currently running latest stock Android 4.1.2 on my Nexus S. It appears that official Google support has come to an end and therefore there is no point keeping the original software. It also seems to me that current version of Android on Nexus isn't exactly a good example of well optimized software which is the reason why I'm looking for an alternative.
My requirements are speed, stability and possibly better battery life. Extra functionality is not important, I'm happy with 4.1.2 as it is. However I don't want to downgrade to ICS not to mention Gingerbread.
So could you recommend me a good alternative rom for Nexus S, based on your own experience? I'm currently thinking of CyanogenMod because there is plenty of people behind it and its really famous so I guess it should be stable and reliable but I haven't decided yet. What do you think?

I use AOKP with the marmite kernel. Works great.

Same here currently on cm 10 stable with default kernel for weeks now it's been really fast and stable. Was surprised. I had tried cm10 when it came out for our device and it was pretty bad stability and battery wise so I went to aosp roms.... Gave stable a shot and wow it has come a looooooong way in such a short time

Another vote for CM10. I'm currently using the new rasbean, but if 4.1.2 is good with you, I'm not sure anything can beat the stability of the stable version of CM10.

Having tried tons of amazing ROMs on ICS, I feel there were more stable and fluid options than with 4.1... That's not to say 4.1 didn't have great ROMs, I'm just saying that it was harder to find a stable, speedy, efficient 4.1 ROM... If you want to stay with 4.1, then I can only vouch for BAKEDbean 6... I haven't tried as many 4.1's as I did with 4.0... From memory, Slim Bean was pretty good... I just didn't like some of the included options...
Now here's what I can say about 4.2 ROMs... Since you don't mind missing some included features like theme chooser, statusbar tweaks, etc... Then I would highly suggest Rasbean with Matr1x CFS 24.0 (non-cm version)... I always told myself that I would never use a ROM without theme chooser... But after trying this ROM, I've discovered that speed and fluidity is way more important to me than a few extra features... This ROM is amazing... I'm getting much better battery life with this combo than with any 4.1 combo I tried... At the very least, give it a try
*edit* in case you see reviews or read somewhere that it's not a "stable" release... I would ignore that crap because I haven't had a single issue with this ROM other than the phone app fc'ing after some calls which is 4G related... and since you're on crespo, you won't have that problem... Everything works on this ROM!!!

Moved to Q&A section....thank you.

Hey, thanks to all of you guys. I switched to CyanogenMod 10 since many of you have recommended it and it also seemed to me pretty solid and reliable. Nexus S now does seem a little bit faster and more fluid however it's hard to tell after less than a day of using it. I won't go back anyway, those few extra features are really nice. My problem with stock JB was that it suffered from some kind of memory leak... quite often I ended up with literally 0 MB of free ram. The phone also got quite often to a state of total unresponsiveness for few moments without any obvious reason. None of these problem has occured in CM so far however for example during heavy usage, when I go back to home screen, the launcher is really slow (1-2fps) for few seconds. But I guess I can't expect much from 2 year old hardware.
You also mentioned several alternative kernels... what can I expect from that in daily usage?

I have not an ounce of lag on rasbean 4.2.1... I didn't think it would get better than 4.1 but it clearly does... I don't think everyone that recommended cm10 has even tried a 4.2 ROM yet... BTW, cm10.1 will be released soon and I'm sure everyone with update then...
For kernel, use airkernel or matr1x... Think of the kernel as the brain of the phone... It tells the phone what to so with the hardware... So you can tweak things foe better speed or better battery or even attempt to get a good balance between the two...
My last time mentioning it... I would strongly recommend you to backup your current setup and flash the 4.2 ROM with matr1x 24.0... That is all

Really it does work that well? Hmm then it is really sad that Google has cut off Nexus S from official updates. I will definitely try 4.2 but I will probably wait for CM 10.1 if you say it will be released soon.

Well I know what the kernel is (I have been using Linux on my desktop for several years ) I was just curious how one can benefit from using an alternative kernel for Android. You say I can tweak things for better speed or battery life... does it mean that I can for example sacrifice 30% of battery life and exchange it for 30% of performance in gaming? What are the limits of this tweaking?

[Q] Best Battery on recent ROM? (AT&T Evita)

Hey Q&A. Looking for a ROM (preferably not Sense-based) that has the maximum battery life.
I've carefully examined all of my applications, as well as tweaked which apps have permission to run in the background, and still only have a maximum of 2 hours screen-on time on the most recent Jellybam ROM version.
I've done all of the batterystats resetting, as well as the 100% to 0%, with no change in battery life.
I'm looking for even a single hour longer battery-wise. Again, though I prefer the AOSP style (as well as CM/JB), Sense is okay.
So which ROMs have the best battery from the start guys? (AT&T HTC One X only please)
Thanks in advance!

I've gotten Sense-ish battery life (maybe a bit worse than ICS Sense ROMs, but better than AOSP ROMs) with AOSP-level performance from this AOSP-themed Desensed JB ROM:
http://forum.xda-developers.com/showpost.php?p=35749360&postcount=517
It's still a Beta, but it's pretty much fully functional, with the exception of recording video - it force closes right now.

Flashed it and for some reason i'm having all sorts of issues. Play store won't download apps, nor will my mobile internet work correctly. Clean flashed (wiped all/system data cache etc) two times, so don't know why.
Gonna give viperXL a try, as it seems to be highly recommended on a few posts I've seen.

Strange, I haven't had anything like that.

make sure to do a full wipe, clear both caches too

Guess you'll just have to try them all until you find what's best for your usage.
Best Rom threads, best battery life threads are not really allowed.

I understand why "best ROM" threads are frowned upon. But as a noob to Android, I find it hard to understand the objective differences between ROMs as there is no such discussion as far as I can tell.

In each persons usage, results can vary wildly from things such as signal loss, a locked up sms app etc.. so it comes down to opinions an that's where issues can arise.
Not trying to be rude to you, or senior members, but that's the law of the mods.

I'm using CM10 nightly Evita build from the 25th i think, and getting on average about 26 hours if battery life. Also have easy battery saver running most of the time, it's actually rather effective. Without it I get about 2 or 3 hours less.

Jellybam gave me the best battery with rohankernel, but as far as gaining the most life out of your device I would stick with Sense and try ViperXl or CleanRom.

[Q] Better Battery?

So right now I am on UnKnown_JB V1.8.1 with Kernel 3.4.10. Before that I was on PAC-ROM v23. The battery life on UnKnown ROM is extremely good, but I do not like the stock feel. I was wondering, which ROM (updated after June 27) has the best battery life without the stock feel?
BAKED BlackBean 9 (JB 4.2.2)
Dark Jelly S Edition Build 32.1
IllusionRom-2.0
Avatar ROM
I want to know which of these ROMs have the best battery life with the least amount of bugs. Otherwise, I may stay with UnKnown 1.8.1.
Also, I was wondering if flashing a custom Kernel is beneficial.
Again, I thank anyone who can aid me. I am only asking in order to save a lot of time by flashing and testing.

I advise ya illusion

They don't allow these posts. Xda wants us to waste our time flashing and setting up Rom after Rom after Rom. They don't allow any feedback comparing roms. You have to read through like 80 pages of posts in each Rom thread to try to get an idea which might be the most stable or suitable, plus most problems people report are to do with their set up or an error and not the roms fault. So its almost impossible to know which may be more or less stable.
I went with viper one s 2.2 and its been rock solid reliable for me. There are lots of others I would like to try and may like better but I don't want to waste hours getting everything set up the way I like again and find its not as stable or bug free as what I have, plus I will lose track of my data usage for this billing cycle.

Which ROM?

Hi,
Am a noob, new to Androids and an old man learning at this stage.
I have a OPO 64 GB Chinese, running Color OS.
I am hiring the services of a young tech to it for me, flash, root, unlock bootloader.
My question is in our expert opinion which is the ideal, most stable ROM recommended by you experts.
CM 11S, Slim, Mahadi, PA etc etc, so once done am able to live with a peace of mind and receive updates when available.
Hoping to hear from you smart members,
Thanks.

All roms are pretty much stable. Now you have to decide what rom you want based on the features offered by that rom.
I use Mahdi and have no complaints about the rom. It's the most featured rom out there while maintaining performance and stability.
Sent from my One using Tapatalk

That's right... We won't answer that question directly here because you have to figure out yourself which ROM suits you best. My advice: Read the ROM descriptions and changelogs carefully, get to know the features provided by each ROM and most important: try it out for yourself. If you have a candidate, just try it for a few days and judge after that if it is usable for you.
I would also recommend you to learn how to flash ROMs and change software on your phone yourself. It is not that difficult with all the guides here and definitely worth a shot. Good luck!

I’ll throw in my personal favorite: SlimKat.
I already tried the stock rom and loved it, but I wanted more customization.
I first went to PA but that rom felt too heavy. Madhi, and did’t feel like that rom was ready for prime time like the stock rom. I also tried Calkulin’s rom and I really liked it because it was almost stock like with a few more features and the battery was amazing! I got more than 10+ hours on a normal’s day useage.
But finally, I went over to Slim roms because of stability, smoothness and speed. I’m still determining if rom has any effect on battery.
So far, Slim is my most favorite. I absolutely recommend it.

A kernel has more impact on the battery than ROM. Although a ROM may supply itself with a "custom kernel" as the stock kernel of that ROM. For ROMs just look for features, stability.... but a ROM won't have a significant impact on battery life, what matters the most when it comes to battery life is making sure your phone properly enters deep sleep without any wakelocks. The phone battery life is still good even if a user has wakelocks on anyways.
Mahdi is pretty prime time and it gets updated quite frequently and the developers are super friendly and responsive to any bugs that may occur. I don't have any problems with the rom.
At the end of the day, try them all out for a couple days and see what you like the most. They're all free after all

XDA is a development site not a support site. As the term "Best" or "Most Stable" is a very subjective term, such members are expected to do their own research, read through the development threads, and decide what is "Best/Most Stable" for them.
The only results that would be posted here are what each member has found to be "Best" or "Most Stable" for them by experimentation based on their phone/usage/setup/apps/signal strength. And at times, these thread spiral into arguments over which is perceived "Best/Most Stable".
Please take the time to read through the development threads, and interact with the members there, to learn all about the software you are about to drastically alter your very expensive device with.
Sorry for the inconvenience and thank you for your cooperation.
