[Q] Best galaxy s rom with low battery drainage - Galaxy S I9000 Q&A, Help & Troubleshooting

Hello there,
i have a europpean galaxy s i9000 with darkys 5.5 rom installed, and im not content with the battery drainage (except in standby with everything disabled it's ok). Previously on base jpu rom it was MUCH better: 1 hour of listening to music cost 4-8% of batterdrainage, with darkys rom it's already 20% and the back of the phone got really hot! (Same for 3g, wifi-usage and so on).
So my question: What is the best rom for least battery drainage?
my best configurations so far were the following:
-2.1 jm2 rom without lagfixes
- 2.2.1 jpu without lagfix/root/custom kernel, but with battery booster from the market.

I flash JPU 2 days ago,and i m not so happy with the battery,so i dont recomend it.

I'm about to try Darky's ROM as it looks like it has better battery life than stock Froyo

There are so many factors that effect battery performance and the individual rom really doesn't have much to do with it. Start with having the most accurate modem for your carrier and go from there. Pick a kernal that works for your application and watch your services.

Hello Friend,
I also used DarkyROM and others which included lagfix and finally i returned myself to the leaked version with XXJPU 2.2.1 Froyo and all what i have dobe is that i flashed the CF-Root trough Odin3 v1.3.
Now, i am more thna satisfied , as I entered in third day running the phone without charging !
All the time wifi is in background running as because of mail syncing.
I am not using UMTS network as i set in network settings just to use GSM, as I never surf from 3G and gprs will do I job regarding the mails.
All lag fixses as I noticed drain battery so fast , but anyway thanks to their Authors for creating them and making us happy with playing with this wonderfull mobile phone.

Hi,
By the leaked version, are you referring to the stock version available for download. Also what did you use as a modem, getting 3 day battery backup is amazing and I will not mind a little lag that the JPU has over darky's rom if the battery life is that amazing.
I have never got battery more than 24 hrs ever.

[Q] Loss of Network Service

I have the SGS GT-I9000M from Bell, was running Froyo 2.2
Decided today to dabble around with rooting and roms.
Followed all the directions to installed Darky's v9.2 Extreme Edition w/ Voodoo 5.4.1 kernel.
Everything went flawlessly and everything runs slick. Except for one small issue.
Now I seem to be losing network connectivity. Sometimes it will remain on "Bell", other times it will just display "No Service" or "Emergency Calls Only".
Have I missed something or done something incorrectly?
Any insight on this would be great.
Thanks in advance.
Also, is there a way to revert back to stock 2.2 if necessary?
Revert to stock via Odin
Darky problems check Darkys posts and FAQS .
jje
Tried and failed.
Went through every Darky's post I could find and can't seem to see anything like this being mentioned.
I even tried the Resurrection version, now my phone is a brick.
Does nothing but reboot over and over at the start.
Can't get into Recovery, only Download mode..
Suggestions?
Go to sam firmware.com download the android version 2.1 update 1 ughj2 or whatever its called. when its done downloading put your phone in download mode but first open up odin. select 512 pit and check repartion. Choose the firmware as pda and connect your phone to the computer and press start wait until odin finish flashing it and comeback and tell us what happened
I was able to get the phone working again, pretty much what you just said.. but with 2.2
Only issue is now I have no data network connectivity.
Zero options for it in the settings, and I've even called my cell provider..
They keep telling me to wait a few minutes and it will reconnect..
It's been a few hours..

[Q] Darky's ROM v9.5 - It isn't stable for me

My starting point...
This was loaded with PIT *512, Odin 1.7, and PDA 20110318_ZSJPJ.tar (ASIA) with repartition selected
Wifi, APN, phone, android market, auto sync, and camera – working
*#1234# PDA I9000ZSJPJ PHONE I9000ZSJPG CSC I9000OZSJPG
*2767*3855# Device rebooted normally after factory reset. All settings lost, the device start appears to be fresh and clean.
Android system recovery 3e
Automatic time updating has never worked for me. I unselect automatic and manually choose Beijing +8.
Darky's ROM v9.5 Installation
Followed instructions found here:
http://www.darkyrom.com/community/i...rkys-rom-on-2-2-2-2-1-i9000-i9000m-only.1041/
Setup Darky’s ROM Configurator
Flashed Dark_Core_1.0.tar with Odin 1.3
The Dark Core kernel does not work on my phone. Still Android system recovery (3e)
Revised ROM configurator to skip kernel as per alternative kernel method
Flashed speedmod-kernel-k13d-500hz.tar with Odin 1.3
I skipped backup step. Fresh phone so no reason to backup
Completed efsbackup
Through recovery, wipe data/factory reset completed
Through recovery, Darky’s ROM v9.5 flash completed
Selected reboot device through recovery screen
The rest of the story...
This is a list of every action I took after completing what seemed to be a flawless installation of the ROM.
Updated phone settings…. Language, time, wifi password, google password, etc.
Sync of gmail, google contacts, and google calendar completed without problems.
*#1234# PDA I9000XWJS8, PHONE I9000XXJVE, CSC I9000OXXJS1, Build Info 2011.03
Opened home switcher app. Set homeswitcher to ‘Launcher’
Checked camera. Pressed home key and phone went back to original setup wizard screen, the one you see when you wipe your phone. I continued to press next to get through the sequence. Home screen switched back to ‘TwLauncher’ appeared to be the only change.
Pressed home button. Ticked box to set default. Selected ‘Launcher’
Tested camera again. I pressed the home key to get out of the app and the home switcher option came up again. Once again, selected to tick box to set the action as a default and picked ‘Launcher’.
Tested camera again. The home button properly went to the default this time.
The Places app does not launch.
Modified some settings inside Spare Parts app. Animation and wifi sleep policy.
Changed faster fix app to show China.
Opened Gmail app, rec’d ‘stopped unexpectedly’ message. Force close.
Tried to respond to an SMS message, rec’d ‘stopped unexpectedly’ message when I tapped the box to bring up the keyboard. Force close.
Opened Messaging app and tried again to respond to SMS message with same result.
Went to settings, modified input method to ‘Touch Input Chinese’, the device shutdown immediately.
Restarted phone. Unlocked screen and rec’d message ‘Process system is not responding’. It stayed there momentarily and then did a very quick reboot. I unlocked the screen and rec’d the same message.
I selected force close. The home screen was black with no wifi or phone service. Touching the applications button opened the list of app icons but the phone eventually the device did its very quick reboot.
I held the power button down for several seconds to force the device to turn off. I pressed the power button in hopes of it starting up normally… with the exception of having no phone service, it did seem to start normally.

Flashed stock ROM and returned to starting point noted at beginning of the post.
Please forgive the post above if you find it offensively long. I have spent the past week reading anything I can as it relates to Darky’s ROM and can’t find anything that seems to relate to the problems I am finding. Admittedly, I am a n00b and this is my very first experience with custom ROM in the android OS. (I made the switch from iOS a month or so ago where the game of JB and unlocks became to frustrating.)
I have installed Darky’s ROM many times over the past week and cannot get anywhere near what I consider a stable platform. Events such as ‘force close’ and system reboots are so frequent, surely that can’t be the norm. Is this to be expected?
From the description in the post above, have I done something wrong? It seems like the most frequent response and solution is to flash the ROM again. I have done that and never seem to get the same response.
I realize this is a custom ROM. I just don’t hear others mentioning the issues I have described so I am guessing they don’t exist for anyone else.
You should tell Darky .
Majority of helps posted on this forum are for Darky roms fact not fiction .

@jje Thanks for your advice. I will take this question over to Darky's forum. I was hoping that the larger pool of potential readers here would be able to offer some advice.

Possibly if you hang around a bit someone may come up with an answer .
Not an answer but you can build your own rom .

This is not an answer, but for me Darky's ROM v9.5 wasn't stable either. It just stopped working every few hours, just turned off my phone without notice etc.
I'm not sure what the problems was but I think there are some unresolved issues with v9.5.
After flashing stock JVK + darky10kernel + Darky's ROM v10.0 RC3, all my problems were gone tho and my phone has never been smoother. But v9.5.. I just don't know.

quite weird how so many people say 9.5 is good, and so many other people say 9.5 is bad
i upgraded to 9.5 from 9.2 about 4 hours ago and so far it seems fine
I did a no-wipe upgrade and am using dark core kernel 1.0 that came with the mod itself
not switching to 10.0 because it requires a wipe cant be bothered till 2.3 goes official
Try flashing kernel 1.2 darkcore
9.5 not rock solid, but not that bad either
I'm running 9.5 for a couple of days now, and although I ran into some minor problems, I cannot say it is that bad. It hang once, sometimes I have a small problem installing apps from the Market, but apart from that, it's OK. I think 9.3 had less problems, so if you want to go for a more stable Darky's ROM, go for 9.3. Or wait until 10 is official released.
Go through resurection
One more tip: I noticed you started from a non-Darky ROM. What you can do (and it's what I did) is install the Resurection edition of Darky's ROM. It's essentially the 9.2 version and you can flash it with Odin. After doing that, you can be sure to have a clean Darky environment. You can even see how that one works, I know a few colleagues who are still on 9.2 and fully happy with that. But if you want to upgrade, it's much easier from there. Just use Darky's configurator after you copied the ZIP file to you SD card. It's easy, and like I said, for me it is pretty stable!
Flash 9.3 first then flash over that with 9.5. I have used a lot of Darky's roms and never once had any major issues with them. 9.5 is a good rom

Told them out of the thousands at least one has a good user experience .

I want to go backwards (I am on 9.5 and battery life sucks).
How do I go from 9.5 to 9.4? Can I just download 9.4 and use the Darky's Rom Configurator and install it the same way I went from 9.4. to 9.5?
9.4 was deprecated due to heavy issues. The previous stable one is 9.3. You can install it with Darky's configurator, indeed.
Bugs will be fixed step by step ....
But I prefer Ultimate v8.2 with Tegrak Kernel ...

[Q] gps not working

Hi
we have 3 galaxy s in our household, 2 of them have a working gps and will lock on, the other one finds about 3 GPS but never locks on .
we are using GPS test from the andriod market to test the phone.
The faulty phone using gps test says inview 3-5 inuse 0) We have sent the phone back to phones4u (UK) and thet sent it to an accridited repair centre.
It came back and the report said it was a software bug
we then retested with gps test and it was only finding 3-5 inview and 0 inuse according to gps test.
All they have done is i think they have just reinstalled the phone back to 2.2 and sent it back to me.
Can you give me any advise on how to fix this please
install jvr -> http://forum.xda-developers.com/showthread.php?t=1139050
Whats the differance between JVR and JVO?
My mums phone is running JVO and the GPS is running fine
can you go from 2.2 straight to JVR?
it has been a bit fixed in jvp/q/r - better signal streanght (snr - signal to noise ratio) due the files updated by samsung - not much but always worth to use latest best files
thats why i always recommend latest firmwares wo any kernels
as samsung never releases sources to latest firmware releases
so you will revert some kernel changes introduced in newer version and not present in kernel builed from older sources
same goes with system files - but in most cases kernels are not touching those
and yes you can go to 2.3.4 jvr straight as long as you will use 3 file firmware and do it as it is said in the thread i linked
Thanks
i will download jvr europe with 512 pit and give it a try will update thread asap
looking forward for your feedback
Many Thanks for your help so far, I have just flashed the Faulty phone with the Links you Provided
However after running GPS Test - its finding 6-8 GPS In View - however its not using any (6+ Inview - 0 Inuse)
is there anything else we could try?
Or do you think the phone is faulty?

i am testing the gr3 atm so cant speak but it seems better
Which zip do i install First and try
Nevermind
GPS_JVR is Stock
Installing GPS_GRK39C as we speak
Ive Installed the files (I think )
How long do you have to wait on average for it to find the First GPS?
depends, should be something around minute. ive got fix after flashing in about 20 seconds
but it depends on snr in your location, and so many other variables
btw enable data connection/wifi so phone can download agps data
without that it infact can take couple of minutes
Does the Phone Download the agps data automatically?
yup =) as long as there is active data connection/wifi
use those apps to test and download agps:
GPS Status & Toolbox
GPS Test
GPSTest

[Q] Battery is draining in a few hours!

Hey, please help me!
I've been using Apex for a long time, and after I upgraded from 9.1 to 9.2 the problems started showing up.
I tried to flash the version with no wipe (9.1 to 9.2) and the phone went into a bootloop, so I flashed back to JF6 and followed the Apex-Flasher package instructions.
The rom was working fine but the battery life are so bad that the phone is almost unusable.
I'm not charging the phone all night, I'm charging to 100% before I go to sleep, turning off WIFI and 3G, and when I wake up the battery is just 5-7% less.
But now with 9.2 the battery is 15%-20% less!!
I tried to flash Apex 10, but it's the same.
Maybe it's because the Apex Flasher package contains AT&T BL? I thing that before 9.2 I was using I9000 BL.
Even when the phone in flight mode and with no SIM the battery is draining in few hours!!
When I'm checking the battry use in settings, I always see "Cell standby" firse.
And another small thing, In Apex 10 you removed a lot of things, one of them was the Buddies Now widget which I like a lot. I tried to copy the APK to the app lib in system, but it didn't work. I also tried to install it but it didn't work. How can I get this widget?
Thanks in advance!
Buddies now widget does not work with JVS build. It needs to be ported again. As for battery life you have to tell which process/app eats your battery?
Check what using the battery most under the battery stats.
You could have asked this question in the Apex Q&A sticky there was no need to start a new thread.
I posted this problem in the Apex thread but no one had answered me, this thread seems to be a little dead.
Anyway, thanks for the Buddies Now answer
As for the battery drain, the first in the list in battry use is "Cell standby" even when the phone is in flight mode, or without sim at all :S
Maybe the AT&T bootloaders not working well with this rom or kernel?
Cell stanby means the phone is searching for network try a different modem, What modem did apex 9.1 had.
But I have full signal all the time.
The modem hasn't changed, it's KC1 in 9.1, 9.2 and 10
try a different modem anyway
OK, what modem can I try? How do I change the modem?
Is there a way to run this rom and kernel with I9000 bootloaders?
There is a modem sticky in the dev section DL the modem u want ro flash place on the phone memory ans flsh it through recovery, No need to change ur bootloaders as they will not effect the phone in anyway.

There are many, many modems.
I believe in the dev section there is a link where people report which modem works best in certain locations, i would check that out.

[Q] Galaxy s Cpu problem? Need Help

Hello people i hope you'll be able to help me and together we fix this problem
I've got a problem with my galaxy s. it seems like the CPU doesn't know to change it's frequences itself. If i power it on, the media scanner starts and the cpu goes 100% (1GHz) all the time. the problem is, that the media scan stops and even after 30minutes, the CPU still goes on 100% (1GHz) that's what the app 'cpu spy' and my battery life say. Then i found out that if i start music player and play some song for a while and exit the app, cpu spy shows me, that the CPU runs on 200MHz or 100 MHz all the time.
today i found out that if the screen is off it sometimes goes deep sleep, but as soon as i unblock the phone, it goes full speed again.. I don't know what causes that as i already removed and reflashed everything, the only app i have installed is CPU SPY
the history
the phone was bought, I was on official 2.2froyo , got bored, flashed to official 2.3.4 JVR , after half of a year a got bored again and flashed 2.3.6 JVZ , everything was just fine, but after 3 days i found something is wrong with my cpu, so i came home, fully charged it, and wanted to reflash 2.3.6 JVZ through odin, it failed and got stuck at boot.ini or something like that and I couldn't boot the phone anymore.. so i had to flash back the official 2.3.4 JVR with 512 pit file and repartition checked. It powered on and booted nicely(the only thing i'm happy of) and i hoped everything would be ok. but it wasn't so i went into recovery mode, wiped everything thanks to the 2 options recovery mode gave me, started the phone, reseted it to factory state again, I even formated the internal SD card and the problem still persists.
so to sum this up, right now I'm on I9000XXJVR 2.3.4
CODE_I9000XXJVR_CL425308_REV03_user_low_ship.tar (286 091 kB)
MODEM_I9000XXJVR_REV_00_CL1044379.tar (86 911 kB)
CSC.tar
watch?v=cLXQn0gOBuA flashed and guided by this video
and the only thing i have installed is Cpu spy, and it just cant get into sleep mode as it is always clocked at 1GHZ
Any ideas please?
I really don't want to flash 2.1 , update through Kies to 2.2 and send it for reclamation
Did you even flash a gingerbread bootloader in the first place?
Most of those issues exist because of having a wrong bootloader loaded for a device running different versions of android

Well, the CSC file was downloaded with the other 2.3.4 files and it worked ok 4 months or so. Just nowadays i have this problem
and phone bootloader update in odin was ticked off while flashing :/
Edit: How do i find out?
I reflashed 2.3.4 jvr once more today (repartition/autoreboot/F. reset time/update phone bootloader ticked off,| pit file,csc, modem, code) and the problem is still there,
when the screen is off, the CPU is in Deep sleep
as soon as I switch on the screen, the CPU runs on 1GHZ continually
any suggestions? :C

Are you running stock touchwiz launcher or not?
L studies slankse
Yes i do.
And for the instance you wanted to advise me to download another launcher, I've downloaded go launcher recently and the problem is still there - the mobile is in deep sleep only when the screen is off :| and when on, the cpu always does something:/
I have no idea then. With go launcher, i have realised the the app revs the cpu to full throttle on the homescreen when doing nothing.
Have you tried android 2.3.5 or 2.3.6?
if you want the bounce effect, 2.3.5 jvs also has it plus better battery life. Try it, i don't have cpu issues with this Rom.
