Sorry for another thread on battery life but u need help. I am loosing severe battery while idle. Just lastnight I lost 60%. I have a I897 using cognition3.04 with firebird kernel.
I have wifi,Bluetooth,GPS off. Using juice defender, and no task killers. And have callibrated my battery, and do not see any roug apps. Battery usage said cell standby and phone idle were using most of the battery.
Im at a loss. Thanks for your time.
Check out my thread below you
I had alot of questions answered in it, take a look.

Everyone has been helpful on this forum, thanks again to all!
Also, the STICKY thread at top of this forum is VERY USEFUL!

Thanks i saw your thread already. I flashed back the stock cog3.04 kernel and modem and did a battery recalibrate. After fully charging and wiping stats last night i lost about 8% (~1% an hour) conpared to the 60% before, so im happy. Im at 45% after using it all of today, Ill see how the meter works after the full drain after stats wipe.
Im pretty sure most of that came from the kernel change, does anyone know any other good kernels.
Same thing happened to me with cognition even after battery calibration, just switched over to Phoenix ROM and its fixed.

Some ROMs use more, some use less. It also depends on kernel, not just ROM.
I have the ROM in my signature below. When on glitterballs kernel, i had 1% drain per hour. On xcalibur's kernel, I have 1% per ~2 hours. Try changing kernel n see if that helps.

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.

Hello,
I was wondering if i did something wrong when flashing, I flashed me phone yesterday, love the rom, but the battery life stinks, today I have been off the charger for 3 hrs, 1 20 min phone call and check download my email and my battery is at 73%. This morning before I unplugged my charger I went into oxdin and removed battery stats to see if that helped, any advise would be helpful, I did flash to stock with oden3 one click and I had 85% battery and plugged in charging when I flashed to this rom. I want to keep this rom as it is super fast and no issues found other than the battery
Thanks in advance for any help

I would give it another day or so. It can take it a little while for the battery to settle in. if that doesn't work you could try flashing another kernel or modem.
Just a few opinions...
Sent from my SAMSUNG-SGH-I897 using XDA Premium App
yes like the previous post
you have wait for few days cz it takes tym recalibrate battery stats. couple of charges and discharges will fix the battery drain
Thank you,
I'll give it a few days and see if it fixes itself, this is the best rom I have tried and would hate to have to change as everything with it is how I would do it if I had a clue how to custom a rom
Thanks
Tony
Like the others have said give it a few days, my battery life VASTLY improved after 3 discharge cycles. Also, another thing to check is the cell standby and make sure that you're not having the 50% time without signal bug. I had that this morning and it drained 20% in barely over an hour.
Hi,
Just a quick one and any responses from personal experiance would be great.
Has anyone used an app to re-calibrate the battery? If so did it help or did it seem to make the battery life worse?
I had a major drain on my battery so did a complete reinstall of tweaky ROM and the drain has stopped. Just wondering if I should bother to recalibrate
Thanks

Calibration did not help me, I have the same stamina... JVH + Criskelo v56 + CF-Root 3.2
from those many many times i have tried to do calibration in all possible ways that has being suggested even waiting a few days for the cycle to end...
my conclusion its bull**** it depends on the rom or apps that are running ....
the only thing it does it shows u 100% when u finish charging in case u dont see it already.
Does it work or does waiting two weeks for battery to settle down work .
jje
My findings are similar to JJE. After flashing a ROM, it will take 4-5 charge cycles (just charging every night, nothing special....may run down to 0% after first charge) before I see a stable, decent battery life.

Ditto, I try not to judge a ROMs battery appetite until about a week, espescially if I was to lazy to flash at 100%.. But I think that is what is meant by battery calibration..
Ok thanks guys, think I'll wipe battery stats next time I flash a new ROM 100% battery

Hello everyone,
I'm running some tests to see the battery consumption on my Galaxy S i9000. I'm using the gingerbread version of darkys ROM.
Firstly, what do you think of the battery life? In this specific test I used the phone in a very light way, made some messages/calls and read few mails.
Secondly, is it normal to have depressions in the battery chart that display less battery than it shows later? How is it computed? Isn't just some logic level of the voltage battery?
Lastly, in the case of buying another battery, is it worthless to be genuine?
Thanks a lot
I have same qestion like you, in the another thread....

Sorry! Obviously I didn't searched properly. Hope someone can clarify us
Is it a gingerbread issue?
Even big batteries will "recover" after heavy use so ur graph is quite normal.
Also be aware that if the battery calibration isnt xorrect then that will lead to weird graphs too. E.g. Losing 1% over 8hrs after flashing a new rom is most likely due to inaccurate battery calibration.

When I install a new rom the battery stats are always deleted? Or it depends?
I also having the same prob...batt consumptions are always the main concern when come to flashing a new rom...Darky's can only last me for 1day with heavy usage and recently flashed to MIUI which can only last for <8hours with the same usage...im not sure why this happen but I am trying with different kernels and see which is the best combination...
I just installed a new gingerbread ROM and guess what.. Using push, wi-fi all the time, gps, 1h youtube video, sms, video call... The battery never ends!! As I'm writing the battery is still 15%. It's amazing the gingerbread in terms of battery consumption. Obviously, something in the other ROM was not right! Guess I'll stick to this battery a little more time.
Btw, the battery stats are pretty normal, no depressions..
Hello.
I was a PA 1.6 and PA 2.X user since last week, when I decided to install stock ROM to check if battery life would improve.
I've been trying different ROMs and realized that battery performance was worst,so I decided to check stock ROM to see if I could get any improvents in battery life.
Yesterday I installed SGN_XX_OXA_KJ1_FACTORYFS stock ROM, but during the night I lost 50% of the battery (I didn't turn Flight Mode on) and now it's draining at 3.5%-5% battery per hour.
I reinstalled the RADIO, but I cannot understand how stock ROM + RADIO can have this much of battery drainage.
Any ideas on what can be happening and how can I solve this?
The only thing left is to format all SD partitions and pray. :laugh:
try slim bean with sync off and just 3g
and check ur battery
if it presists then try flashing xxlrk or xxlr1 modem

Yes, I already bought better battery stats but haven't find any wakelock issue... it looks as if it got normalized and now I'm getting 1.5 % per hour, which seems pretty decent...
