Awful Awful battery life since Darky's ROM

I have always had stock ROMS with my i9000, ending with JS7. I read the battery problems people had and I always counted myself very lucky that my phone had a pretty decent battery life.
Daily I would SMS (a lot), the odd phone call, quick blip on the internet (3g), lots of angry birds and doodle jump! I would get at least a couple of days before it went into the red.
Then I made the big mistake of installing Darky's ROM, it looks nice and feels a bit snappier, but now the battery is in the red in the evening after a full nights charge. This is even after severely curbing my phone use to try and extend the life. I have tried all the wiping tips and tricks too.
Same apps, different ROM. Darky's is an absolute nightmare for me and I will be going back to stock.
So is the ROM just another variable in the mix of battery issues, or the main offender?

Hello. I've the same battery drain, and I think it's very annoying when at evening you need to charge it again without using strongly the phone. Otherwise the Darky's rom, (I'm on 9.3) is very nice and marvellous, but this battery drain issue makes it worse.

Have you tried using spare parts to see which app is sucking baster or cpu? Did you download the rom configure tool from the market? Which gallery did you instal worth the rom?

This and:
have you let the phone drop below 10-5%?
Flashing screws up the battery indicator (how much depends) and it calibrates itself while in use. Letting the battery fall, or even the phone shut down by itself can speed up the process quite a bit. This helps only if there is no battery hungry app that's eating all your powrz though.

I haven't tried to see if there is an app sucking the life out of it because I never had any issues under the 3 or 4 stock roms and I haven't d/l any other apps. The battery deterioration started instantly I flashed with Darky's. I don't know which gallery it is, it came with the d/l. What ever it is, it doesn't work! No, didn't use the configuration tool.
I must admit I haven't let it run under 10% as I want my phone with me working. But wouldn't this manifest itself when I updated the stock firmwares?

ok mate, firstly search the market for the Darky Rom Configurator, shoudl be easy to find, you shoudl be able to reflash without wiping all your apps, run the config app first and pay special attn to the 'Lockscreen wallpaper' of the tool, there aint many options to choose. Got the gallery drain bit mixed up, sorry tired
If i was on my own PC id give a bit more detail but its pretty straight forward.
Im running 9.3 and get a full days mid-heavy use, i normally go to bed at 10-15% which is fine with me

cheers for the advice mate, I've just grabbed the app so I will do the flash in the morning.
I will report back my findings!

Just a thought but Darky's Rom uses JS5 and wondering if has something to do with the modem? Just a theory but wondering if you could replace back to JS7 and see if that helps. Just a thought. I'm used to a day's worth of battery myself these days.

The faster you make the phone go the more power you use darkest Rom are ok but messed with too much

I got really bad battery life for the first few weeks using darky. But now the battery life seems to be longer and more stable and average. I did do calibrations a few times tho.

You won't get better battery with Darky ever.
I played around quite a lot, 9.2, 9.3, calibration, fresh system, darky rom configurator, different kernels, lagfixes, no matter what, my battery drain was mad. It's a quick and smooth rom, but that's the downside of it.
I switched back to Doc's rom via kithen with same kernel, and quess what? No calibration, no playing around, nothing special I did and battery life is brilliant! Of course it lags here and there, that's Doc's drawback(no lagfix applied tho)

You will often find that if you flash a number of roms you get battery drain . Apart from the actual rom itself you need to flash to a clean firmware reset battery stats use a suitable modem charge battery once using bump charge method then wait a few weeks for it to settle down .
I am using rom kitchin since Darkys killed my battery life months ago .
JPY and JPY modem no complaints about excess battery life .
But i did flash back to clean stock before custom rom and wipe everything .

but this is true even if i use a kernel mod.. instead of a full flash? i think that a stock rom with custom kernel made for battery lasting is better... or not?

Have u all tried Battery Bump Charging?
Hi, I am not a Galaxy S owner but I am doing a research on this issue for a friend.
I am a Milestone user and I am a ROM slut (I flash many ROMs back and forth)
So I am very familiar with cases where after flashing a new ROM, your 100% fully charged phone is actually 60%/
Here is a posting on a few ways you can do a battery bump charge. When you perform this battery bump charging technique, u will be surprised to see that your 100% fully charged battery is actually not 100%

I have absolutely no battery drain, 10% lose after 1 day (with playing calls etc included), however I've applied my little solution, deleting all the suspicious system apks

Definitely no battery drain here. Auto-rotation and GPS is ON all the time, played orientation-based and 3d-intensive games multiple times, used Google Maps (just had a nice tour today here in Japan )
By the way I haven't charged yet since I installed this rom 2 days ago.

samsung finally solved it or you did not have the problem before?

same for me right now i am at 1day and 8 hours with wifi on the whole time 3 hrs of calling and texting ,few games,radio etc i always have had the battery drain in the previous roms so this one is looking good

No drain here. With one charge phone now survives two days of intense use.

I surely had it before that is why I started this infamous thread: http://forum.xda-developers.com/showthread.php?t=1039696

No unusual drain here.
In fact this is the best battery efficiency out of any rom (except stock 2.1) I've used. Down to 64% after 24hrs with pretty low usage, which is subjective. To put it in perspective I rarely got past 24hours with typical usage on any 2.2 rom.

Well, it depends on personal preference , but for me bloatware is software that I will never use, or use someting else instead of the preinstalled one, for exaple : layer,mini diary, write and go, thinkfree office, stock audio player, swype, stock gallery app, samsung apps, touchwiz+widgets, live wallpapers,dual clock, etc.
Of course you need root, and titanium backup to remove, or you can delete the apk`s manually with root explorer, just don`t remove crucial stuff. You can search on google, or in the forums for a list of files,that can be safely removed.

For me it has been so-so but I am letting it drain to calibrate now. Maybe it just looks like it's so-so.

DID YA HEAR THE NEWS? Vibrant CM7 is now (almost, mostly, certainly) STABLE!!!

The first release candidate version of cm7 for the vibrant is now out, check out the rom thread here: http://bit.ly/jro3pH. Flashy, flashy, flash! If you're as stoked as I am, say so below.

****, I think ur right, if this isn't what I think it is then I'll request the thread be deleted by a moderator. If this isn't stable then it should be deleted, but if it is then yay! I was just so excited by the possibility of a fully stable CM7 rom, my impatience got the best of me I think .

It depends on what your definition of stable is.
For some stable is good battery and gps.
For others just how fast and appearance.

It's good news. Don't mind negative nancy. This signifies that we are one step closer to perfection.

GPS? That's a good one, what do you think? Just messin', but to be honest I don't know, but I would guess no. On the battery life, I would guess yes. The GPS on my vibrant sucked on the stock rom anyway, so I gave up on the featuee looooong ago.

Battery life is bad as always...or so i heard in the thread. Might try it later, but definitely not staying on it. Battery life is too important for me.

For me stable is when finished restoring my apps in cm7 or miui it doesn't say "process gapps.framework.com has stopped unexpectedly "

If you have been keeping up with the nightlies at all, this is not a major change from Nightly 36. However, the devs (especially atinm) have been hard at work trying to hammer out issues like bluetooth and the mute/unmute bug in order to push this over to RC, and soon (hopefully) stable. That being said, GPS is still not functioning, and battery life on the stock kernel is quite poor by my standards (I've gotten 8-10 hours max on light to medium usage). From a usability standpoint, it is quite operable and quick, however. On a fresh install I have gotten no force closes. In that way the ROM itself is quite stable. Several features are just not fully functional yet.

then don't restore from a 2.2 ROM.

Not everyone has bad battery problems with this! i sure dont and If u had read the CM7 threads u would see that This is as stable as its gonna get without further gingerbread source leak. The mute/unmute problem has been fixed from i have read, But there is no gps But its sure stable enough for most people as a daily driver.

I have the same problem w/ CM7 as I do with the rest of the non-stock roms. I lost data within 24 hrs of flashing. There seems to be an issue with some phones and maintaining data after rooting go figure.

My cm7 is just fine. I don't use GPS do that doesn't bother me. I get about 7 hours of medium-heavy usage, which is just fine for me. Cm7 shows how much of a beast our device is. I have no Oc and I get 2011 on quadrant. When I did overclock to 1.6 I got 2908. I get no problems though.

Not everyone has battery problems because not everyone has ever gotten "good" battery life.
For those of us who have gotten battery life in the I-only-need-to-charge-ever-two-days range, the battery life in CM7 (most recent I've used is #36) is horrendous.

How to get a good battery life!

Well I don't no where to start really as I know I will get told off for making a new thread about battery life!
But this is hopefully some help for people out there that are trying to get a decent ROM and kernel to improve your battery life, well mine has really improved since flashing my Samsung GS2 with Lite'ning ROM 6.1 and flashing the kernel with SpeedMOD T-40.
I have spent lots of hours reading forums about battery life, I think I have tried everything known to man about this phone, somethings worked well somethings didn't, I wanted to get a decent battery life with out sacrificing any features I love about my phone!
When I got into rooting, about 2 months ago I was a n00b, but I stuck to it and learnt a lot each day, it's not easy and you can't expect someone to tell you how to do it, you have to read up about it like everyone else!
But anyway back to why I've created a new thread, well after installing Lite'ning ROM 6.1 at the beginning of the week which I really like as it keeps the Samsung software, I've used TB Pro to freeze the Hubs as I don't use them, the battery life wasn't what I thought, in fact I think I got a better battery life with the stock rom unrooted
I did some researching and found that the kernel can make a difference to (I'm still learning) so after reading some forums I learnt that speedmod kernel worked well with Lite'ning ROM, as It was just the kernel that came with the ROM, ninphetamine 2.0.5, so I flashed the kernel last night with Odin and within minutes I was back up and running.
I then charged the phone 100% and then use a battery calibrator app to wipe battery stats, I then did a basic test which I previously did before, I went to sleep with a fully charged phone, I left everything on: WIFI, mobile data network and sync on set my alarm clock and went to sleep (p.s I checked a few websites so battery actually went down to 98%)
8 hours later I woke up checked my phone to see what % it was left one, previously on stock ROM with same set up my phone would be on 65% due to the Android OS bug running high! This time it was on 91%, so that's less than 1% drain an hour! Happy or what!
I know some people might not say this was a actual battery test but to me it is and I can see a big difference, funny thing is the AOS was showin 35% in batt stats, which is strange!
Now as I write this at 1pm my phone has been on for 14hrs and I'm still at 75%, yes I know the first 8 hrs was in standbye, but I've had a lot of notifications come through from G+ this morning and I'm pretty happy with what I have got set up now, without compromise as well!
I will upload a screen shot later if any wants to see when my battery stats when its down to 1% etc
I hope his helps some people out there, but I wanted to keep it simple for some as I was once a n00b (might still be)

Cool, I did try CM7 but it was a nightley, build 68 I think, if they had brought the stable version out a week earlier I would be on that now, but I hear there are still bugs?
At least with Lite'ning its completely stable plus I like the look of the neon blue effect
My battery is on 64% now, I think I can go 2 days with this now

I'm on CM 7.1 Stable now and now even after 2 days i still have almost 40% battery left out, though on stock i never got more then 1 days

I first rooted it with superoneclick and it downloaded odin and flashed some insecure kernel first and then rooted it
Then i just installed CM 7.1 with Rom Manager, not sure which kernel is it

if you are gonna try cm7 try the latest nightly build....thats pretty more stable than the "stable" version...i think build 83 is out today and that will have pretty much more bug fixes and i hope they can get that browser lag fixed and thats pretty done deal for me to switch over to that completely

It's most likely not a ROM issue. I tried Adams and CM10 and had similar battery life. Make sure you turn off google now (just the cards that need to know your location constantly). It might also be that your update didn't go that well, so you might try a factory reset. It could also be a misbehaving app, so when you do a factory reset, maybe test the ROM before restoring/reinstalling your apps. Also, the more information you give us the better we can help. Good luck!

Thanks for the info. I installed the stock factory image 4.0.4 and then waited for the official OTA. I updated and all works well, but I get around 15 hrs on a full charge with some Whatsapp and Facebook use. When I use it more intense with more screentime the battery drains the most. I think a factory reset wont give me more battery life then this, but I know my drain was not so big while I was on ICS.

By the way, which one is the most stable; CW10 (That chocolate river one??) or Jellybelly?

Sounds weird. But also keep in mind that there are still some apps that don't cope very well with JB, and Facebook has never been Androids best friend . But it doesn't make sense that it's only during screen on, most people report issues related to google now and apps doing **** in the background. If you want to switch ROM anyways, I suggest you use Adams Jellybelly, it's mostly stock (less features means less that can go wrong) and it includes thalamus kernel, which is IMHO the best JB kernel at the moment. I do not recommend any CM10 based ROMs if you're after stability. I assume you checked your battery stats and didn't find anything?
Edit: Chocolate river was abandoned when official OTA came afaik, so definitely Jellybelly . Make sure you do a full wipe though, if something's wrong dirty flashing isn't worth it.

Sounds good to me. Downloading Jellybelly now. I checked my battery stats and didn't find anywhing weird. I dont have much apps installed so there is not much that could give issues. When I leave my screen off (at night or while working) the battery life is not that bad. It's weird, but JB is still very fresh and new, so I'll just try some other roms =)

I am currently on JellyBelly and the battery life is definitely not better than stock for me. Battery drains like crazy when idling.
BUT, I do have Google Now activated. So really make sure to deactivate if you do not need it.

IMO all ROMs should give similar battery life.

Even with Google now turned on the battery should last some time. Do You get the same time as with ICS when it's deactivated? If not, something's borked .

Even if the battery life isnthe same with Jellybelly, the performance is great!
