Strange battery drain

Happy new Year to everybody!!!
I'm having a strange battery drain issue with my phone...
Since I flash Darky's v7.6 I start having this problem-maximum 14 hours battery life without playing or using heavy apps
Before I get 26-30 hours in the same use
I flash 7.7 (both wipe and no-wipe) but problem stays.
Factory reset for sure 6 times until now.
Change kernel to Speedmode but the same
Battery calibration been done more than 10 times without result.
I flash v7.0 now and still having the same isue!!!
It's very annoying
Can anyone help me please?

Its the firmware JPY. Wait for a fix, go back older firmware or turn off wifi.

So you mean JPY is a battery killer?

Happy New Year!
I've had JPU, JPX and now JPY. Somewhere in between I had XWJPH which is the official 2.2 for my device (HKDCOS). The 2.2.1 firmwares have almost the same battery life as the official 2.2 while being much much faster. They all have more bat drain than my eclairs (JM2, JM9) but not dramaticaly. I can make 40-48 hours on 2.2.1 normal use, and I did 48-60 hours on eclair. I think it has to do with what apps you use. Do you have battery stats?

O.K. let's see...
Last night I let it charge untill the "100% charged notification" sounds.
Unplug charger,wait 30-40secs and plug it again.In order to be sure for maximum charge depentless battery icon.
I forgot to deactivate wi-fi(although I think energy consumption is the same) and 10hours later battery icon shows 93%.
Battery stats was almost zero,exept Wi-Fi On(99.9%) and Wi-Fi Running(99.9%)
I thought "desent amount of energy consumption" and then I only used the browser for 15'-20' and battery icon dropted from 93% to 88%!!!
2 days ago,I installed autokiller in order to switch off background apps-just in case that any of my installed apps consumes energy.No result at all....
[email protected] I'm running over JPY for over 2 weeks and had completly no prob at all-just as tsinc sais,I manage to get more than 24H in normal usage
Problem started since 7.6 Darky's been flashed
Then,I flashed 7.7 no-wipe,7.7 wipe,7.0,7.5 and still no problem solved...
And I get tired from continuesly tries of re-customize of my Galaxy

Samsung have changed the WiFi driver for the 2.2.1 Firmwares. As I was on the JPY I had this huge battery drain too. So I decide to take WiFi driver from JPA. They work but I have first to test if this really give me less power drain.

Όχι φίλε αλλά δεν πειράζει
I'm not using Wifi cause I have an "unlimited" (=3GB) data plan. Wifi drains a lot on 2.2.1. I think "hardcore" or somebody started a thread about it.
I'm also tired of flashing and resetting.... Any news about 2.3 ?

I did flash the jpa wifi drivers dosnt seem to affect drqin too much...

I`m using Darky`s 7.5 and the phone has been unppluged 51 hours ago and i still have 38% of battery, although the battery i got with the new SGS i recieved from orange is way better than my other SGS, it last for 4 days with modderate usage, and it should get better as it is new and it has to get a few charging cicles to increase battery life a little bit more. The usage is the same as it was on my other SGS, music, movies, internet, mail, messenger, calls etc.

I`m using Darky`s 7.5 and the phone has been unppluged 51 hours ago and i still have 38% of battery,
Much the same for me on that version but later versions enormousness battery drain . Different rom battery drain about normal .All JPY .

I have it too on JPY now. Strange thing is that everything was good for like a week after flashing, but then suddenly battary started to loose charge like a madman. Dunno, may be it's a Skype that i have installed recently, but i dont launch it and the drain is still there.

I've been looking at youre battery stats and it said its been 26 hours since last unplugged I still have 20% battery left, it also says the the phone wasnt sleeping fot 11 hours out of the 26. What could cause this?(the screen was one for like 1/2 tops

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%

Thanks for responding .
What rom would you recommend?
Sent from my GT-I9000 using XDA App

What kernel are you using?? im on 9.3 with dark core 1.4,, i find in take sometimes weeks to see the full result of battery after changing roms/ kernels.. My opinon is darkys 9.3 with speedmod K13c kernel was the best setup, still after wiping batt stats it was a week b4 the full potential of the battery was seen. Also make sure you follow the steps to wipe battery,, ie turn fone off and charge to full then extra 1/2 hour b4 wiping stats.

Personal recommend is not any Darky rom reason most help posts on here are that rom .
I use Rom Kitchen and build my own rom .

I would recommend A darkyrom!
I am now on 9.5 with the 1.4 Darkcore Kernel and my battery lasts for 2,5 or 3 days.
I have wifi or 3g enabled (the whole day besides night), gmail on push and facebook sync.
I use it as mobilphone in my job so i have many calls a day.

You must have one of those batteries that run on pure magic.

I have recently started running Darky's Extreme Edition v9.5 with speedmod kernel, and so far battery life has been fine. 3G is on all the time with wifi on for a few hours a day.

Thanks boyz & girls
I installed dark core 1.4 ; see how that works

Battery life on custom roms

Hey guys im keen to know your experiences with the various custom roms out there.. I have flashed villianrom today as my first custom along with various kernals but have had constant drain issues..
Looking at my battery awake stats it seems as if it never sleeps :-(

I don't have Villian ROM but from reading the comments on thst thread this is one of the best as regards battery drain so im amazed you experience high drain.
I run Cognition and am happy with this.

You can see it just gettin eaten away screen off doesnt stop drain note the awake vs.screentime i have tried 4 kernals to no avail

Put on watchdog and let it run in the back ground and see if it's any app or widget misbehaving.

I was on Villain too,1.4 to be exact...drains as well,now on Litening 2.2,after resetting batt stats,best so far screen on time almost 5 hours, using mostly wifi..but with 3G,I get around 4hr 30mins...I usually leave my wifi on all the time at home,and switch on data only when I leave...

literom 2.2 doubled my battery life (no exageration) coming from stock rom. impressive.

Some extended idling:
Cognition 1.13 with CF KG1 Kernel, Phone undervolted as in screenshot + GPU @ 750mV for both states.
Android OS still taking 1h15m CPU time in that screenshot, which, in my experience in this case is I *think* because of Skype running all the time there. Also Trillian connected to multiple services running constantly with Wifi.

I'm using Cognition 1.15 with modified 1.4 ninmphetamine kernel, very good battery life so far! (probably the best compared to villainrom and litening rom for me)

Having fixed my awake issue my battery life is reasonable but i expected betted with villainrom + nenphetamine custom + undervolt.
We need to guage some good comparisons id like to get an extended idle test dont know if i can leave my phone for that long. LOL
Btw How did you undervolt gpu?
Sent from my GT-I9100 using Tapatalk

I would stay away from these newer kernels like Nephetamine until they actually mature. I alslo tried some other custom kernels and they kinda drained the battery way more. So I'm sticking to a plain kernel like CF for the moment. Also seems better to stick to the normal ondemand governor.
Undervolting GPU via Tegrak Ultimate, it's worth it imho, especially since I basically shaved off 25% voltage without any issues.

Cm7.2 Battery Drain

I flash CM7.2 few days ago and I'm fall in love with it
But, 5 days later, I'm not impressioned with battery life on CM7.2. It is better on stock ROM I cleared battery stats after flashing, but battery duration is not improved. CPU governor was INTERACITIVE and battery have life duration about 6-7 hours with low/medium using. Unacceptable!
Then, I change CPU governor to ONDEMAND and battery is better for a 1-2 hours. But, not better enough. 8-9 hours with medium usage is still smaller than with stock ROM (12-13 hours)
I won't to restore stock ROM, a love CM...
My dipslay have brightness around 30% (on stock was on 50% or on auto) and I thing that there is some issues with brightness in CM7.2.
Before I reboot phone, battery level was around 60%. When booted again 66%. Few minutes later, it was 60% again. That you can see on screenshot.
Every morning when I wake up, CM showing battery level for 1% smaller than 8 hours ago. But, 10-15 minutes later, it drain 10-15% battery.
I'm using stock kernel.
May someone help me to fix this?

Are you sure that reflashing will solve problem?

Did you flash another kernel ?
I'm running CM7.2 for about 4 months now, and previously RC1, RC2 and 7.1, and I'm not having any issue.
I use the interative governor (min 245, max 1024), I get at least a 12 hours battery life upon normal to heavy use.
If I don't use a lot my phone, I can get up to 36h.
I remember I tried LordModUE 8.9b7 kernel and the battery life was better and performance excellent (governor was smartassv2).

How to change kernel from stock to LordModUE?
Thanks

1. Download the last available kernel : http://forum.xda-developers.com/showthread.php?t=1085725 or directly : http://blackice.omca.co.uk/download...ger-kernels/lordmodUEv8.9-CFS-b7-2WCR-TUN.zip
2. Put the zip on your sdcard
3. Reboot into recovery
4. Make a nandroid backup !!
5. Flash the kernel
6. Reboot and enjoy
EDIT: another good thing is to use currentwidget (https://play.google.com/store/apps/details?id=com.manor.currentwidget&hl=fr), do a full charge until you reach 0mA, then reboot into recovery, wipe your battery stats, let your phone reach 0mA again, then unplug your phone. This should fully reset your battery, and let your ROM properly calibrate it.

Is this correct?
EDIT: After flashing, my Wi Fi not work... There is ERROR when open Wireless & Networks...
EDIT2: I reflashed kernel, wipe/factory, wipe cache, but i cant start Wi fi
What to do?

Yes.
I was on CM7.2 a few weeks ago. I got pretty good battery life. About 2 full days.
I only used 2G & WiFi.

One thing you have to know about flashing a new kernel is that you absolutely need to first boot the ROM with its original kernel first !
As you seem to have many problems, you should:
- full wipe/factory reset, reformat everything except your sdcard
- check the md5sum of the zip (rom especially) on your sdcard
- be sure your battery is fully charged
- flash the rom
- boot it, do not link with your google account
- let your battery charge again
- wait a few minutes
- unplug your phone and reboot
- link your google account
- test if you still have a battery drain but do not install any application, as some of them could cause your battery issue
- make a nandroid backup
- flash the other kernel if needed
- restest battery draining
Hope it'll help !

If you're still having battery drain after following all the useful tips you were giving, it's a possibility it could be the battery it self. You may want to try a different battery to see if you get better results.

Sorry, just lurking. Do you have a GB radio? I've found that running an ICS radio w/ CM7 causes overheating & major battery drain on some devices.

Batteries can go bad fairly quickly.
You could always reflash. Sometimes a fresh wipe is nice (no pun intended)
