hmm. to the best of u guys knowledge, can i hear from u guy which combinations (roms, kernel, modem) is the best for batt life?
i had tried the wiping of batt stats, but the result is almost the same. my galaxy s can hardly last for a day with normal usage (facebook, few mins of games, texts)
kinda disappointed the batt life of galaxy s. lol
Overall Darky rom tend to have low battery life, drain, etc. I tried first with Hardcore's kernel, then Voodoo, which was even worse. The idle drain was not that bad, but when I used the phone... 2min/1%!!! That was mad.
So I put back the old and reliable doc rom with speedmod, and although it's not that smooth, the battery life is pretty powerful!
(no lagfix)
would be kinda easier if you did a POLL here which kernel to use for good battery life.
I am on stock JPY 2.2.1 + speedmod and my SGS battery almost doubled.
Ive heard the Damian's kernel with undervolting is very good for battery life
ok polls are up.
Do let me know if i missed out any good roms / kernels combinations, as I gathered them based on popularity.
and also if possible, share yur opinion on the performance of the roms / kernels that u are using. thks =D
more polls pls!
It all depends upon the way you use it. I prefer Stock Kernel for battery life.
Jve gingerbread modem has made the biggest improvement in battery life for me
Stock JPY, Insanity SpeedMod OC-1200Mhz/UV, ext4, JVE gingerbread Modem,

Anyone have an opinion?
It varies by rom and phone. There is no clear way to know how your phone will react unless you flash a rom. Also, these threads usually get locked for the reason I mentioned. Flash and test is the best policy.
This is my captivate. There are many like it buy this one is mine.
Rom is pretty much personal preference, the kernel with the best battery is Speedmod, hands down.

I think you need to find a new partner.
checks the roms and kernel i am using. 1 hour 55 mins calls with 18 hours standby, and still have 71% left
I've had great battery life (around 3 days of light usage) with Darky's 8.0 + Speedmod K12I + JL3 Modem on my first Captivate. But as flashman2002 mentioned, your experience may vary. I haven't been able to get the same amount of battery life on my current Captivate so far, so I'm in the process of trying other ROMs myself.

For a non OC/UV kernel, I'd agree.
With all kernels included, Glitterballs' (and I assume setiron's) starts getting better battery life with undervolting. With UV settings of 175/150/150/150/125/100 at 1.2GHz, I get better battery life than Speedmod. I'd probably get even better battery life if I backed it down to just 1GHz.
Which rom has stable and longlife battery?
Cause of my friend just take first smartphone captivate ( She is older and low tech )
I try serveral roms but does not get a stable rom. Hope sombody will help me
The Darky ROM has been very stable for me. You can find the page for it here:
http://forum.xda-developers.com/showthread.php?t=890429
It is still being updated on a semi regular basis. The battery life is better than normal too.
I really think battery life has to do with the kernal. I might be wrong but I think you should look for specific kernals and use them.
And I think most roms are stable. you can try cognition. Assonance. Darky
I personally like darky the best so try it out!

Yep, the kernel has the largest part to do with battery life, but it's not the only thing.
If you're into tweaking, I recommend glitterballs' kernel, steam or regular. Undervolt and disable overclocking and you'll get utterly ridiculous battery life. 69% battery life currently with over 21 hours of uptime and moderate usage.
As for a rom, I'd recommend Serendipity, or if you don't mind the Samsung glass lockscreen Cognition 3.0x seems like it has a lot of promise (though I haven't tried it myself as I hate that lockscreen).
I have flashed many roms, and ive noticed the biggest diff. in battery life is definitely with the kernel, i am running docs rom 7.5 http://forum.xda-developers.com/showthread.php?t=882397 that i cooked in the kitchen. with Hardcores speed mod kernel http://forum.xda-developers.com/showthread.php?t=893880 and androidena theme http://forum.xda-developers.com/showthread.php?t=770507. I have went thru many updates with hardcore's kernel, he updates quite often and docs rom is updated quited often also, and seems to be one of the better rom's and the dev. he is always there to answer any questions. Now to the point i have went to full cycles with my battery fully charged and ran to dead, i have sceen shots of both cycles. First batt cycle i went 1day 6hrs from last plugged in. 2 hours of screen on. 20 min of voice calls. the next cycle i went 1 day 5 hrs with 13% left, with roughly the same screen on time. I have never found anything better than this, so i'm staying with this combination, and update the kernels reg. and question pm me if you'd like.

thx so can you introduce which kernel have long life battery
I mainly flash with Cognition or darkys ROMs. I've found that darkys gives me both better battery life AND a more stable experience.
I would use hardcore speedmod kernel. Link is in my last post. 500 hz cwm I'd what I chose to install thru recovery.

Fellows, i just bought my SGS a few days ago , and the moment i bought it i upgraded it to Arabic stock froyo and a friend recommended to use stock+Voodoo-5.0.3-Froyo-GT-I9000-XXJPX kernel
i used it , got 1424 on quadrant and it was very nice in performance but i got strange battery life, it didn't last for more than 10 hours with everything switched off.
so i returned back to stock froyo (pda I9000 jpjpf, phone I9000 jxjpd) and now i got nearly 24 hours of battery life.
what confuses me is that, during using voodoo, the battery was during the first 2 charging cycles of its life, and when i returned to stock froyo , it got into the 3rd charging cycle, and now its moving on towards getting better in battery life.
so my question is , do you think that the kernel was responsible for this strange battery life, or the battery was warming up and needed to be charged and discharged to get into its performance.
also , any suggestions about kernel for battery life with good performance, personally i did like the phone when it was on voodoo @ 1424 on quadrant
please help , and sorry for explaining a lot
thanks
Quadrant is a false test when it comes to use and responsive phone .

thanks for your reply
i did like the phone when it was on vodoo, regardless of quadrent
my aim is to know about battery life

Read the battery faqs and posts on this very page .
But battery life is very very variable .
jje
i am afraid that battery faq does not have an answer to my question
i want to know if the change in kernel is responsible for that strange battery condition
or it was that the battery was at its first charge and discharge cycle?
Going from 10 to 24h of battery life, it could be a battery stats problem, it happens when changing ROMs.
But to answer your question, I dont think voodoo is responsible for the battery drain. Personally I use SpeedMod (without lagfix) with Froyo JS3 and it works really well battery-wise and performance-wise.
you don't think that voodoo is responsible ,
well that's some good news for me actually cuz i did like my phone's performance when it was using voodoo's kernel
thanks for sugesting speedmod , will read about it for sometime and see if i dare to take this action again , cuz battery life is a must for me due to my work
i can't stand the phone that needs more than one charge per day
any more ideas everyone?
I also use speedmod and battery life is excellent. Even with heavy use I get over 24 hours no problem. If I was to use it just as a phone I think I could get 3 days use.
And yes, I agree that your battery stats were probably a little messed up and should settle after a few days of use.

I'm using SpeedMod with SeaARMS' JL2 ROM and the battery lasts much longer. If you have a Galaxy S on Bell Mobility it's the best option to keep the 850Mhz radio working.
fiancees captivate is currently running cm7.1 rc1, with whatever kernel was required to be used from the old 7.0 nightlies.
battery life sucks, maybe 12 hours with light usage and its <15% left.
id prefer to stay away from touchwiz if possible. what rom or kernel, or combination of the two would give the best battery life/stability. I really dont want to mess with OC/UV. I was suggested the glitch kernel with cm7 but dont know if i have to mess with OC/UV to get the best battery life. any help is appreciated, she is tired of her phone dying early in the evening.
All depends on the person. ROMs usually don't drain battery. The biggest battery drainer is the modem, then kernel. Go try Serendipity VII.
I used Cog 5 for a long while and was getting good battery life.
Hi,
Whether I'm on the latest SlimBean, CM10 or CM9, battery life is always bad for me. I don't have draining apps and when the phone is idle it's not using battery at all. The problem lies within usage, when I'm using my phone, the battery life goes down too fast (when I'm using Whatsapp and Gmail. Especially when you compare it to stock.
I've done a bit of reading and many people suggest the Modem and Kernel files can have a huge impact on battery life.
So, I wonder, what would you guys recommend to increase my battery life during usage?
I've found this thread with modems: http://forum.xda-developers.com/showthread.php?t=1870460
(My wish is a fast phone with a ROM that looks nice, like the latest SlimBean, but I appreciate battery life more. However, a rooted Gingerbread stock ROM goes so slow...)
