I have tried both Eugene's and TeamWhiskey's ROM's.. Ginger Clone, OBSIDAN and ONYX. And all 3 have sucked down my battery in about 12 hours flat with me doing nothing to the phone but loading SystemPanel to monitor the CPU and battery. With all the ROM's the CPU usage has been between 3-10% while in idle. zero phone usage. I have refreshed the battery with every new ROM load.
I was previously using TeamWhiskey's 2.1 Bionix Fusion and was seeing between 1-3% CPU usage at idle and had the battery lasting well over 24 hours with minimal use(checking email, couple short phone calls)
Am I the only one having this issue?? Does anyone else use SystemPanel to monitor their CPU usage and can say what their CPU is using during idle??
Thank you for your time and any help/info you may have.
I don't use the modded versions of Froyo but Stock has awesome battery life from my experience. JL5 is looking great as well.
You or anyone else happen to know where I can find a copy of the stock 2.2 ROM/kernel?? I have an unlocked phone in Japan and it's not supported here, so I wont ever get any updates.
Yes the custom roms have terrible battery life. They always have. However, the stock roms have terrific battery life. After a long day of heavy usage I am at 50%

There isn't really a stock 2.2 Rom for Vibrant because it hasn't been released yet. We have leaked builds (JK2, JK6, JL1, JL4, JL5) that are candidates for release. When they actually release Froyo for Vibrant, that will be your stock froyo rom.
The key to great battery life is using the Stock kernel. Flash that kernel on any ROM and enjoy not having to watch your battery indicator all day.
yea, just read a thread about people complaining about that.
guess I'll just flash back to 2.1..
Thanks for all the help.
I flashed nero v2 w/ voodoo and i reset the battery stats, and now im having trouble draining the battery down to nothing.
Fear the beard...

I'll give it a try.. nothing to lose.
To drain the battery, I usually turn on Bluetooth, Wifi, GPS, all the good stuff. Then I downloaded this one Flashlight app from the Market which essentially displays one color full screen, default white. Crank up the brightness and run that app on white and it'll really put the hurt on your battery.
Edit: Today I learned that this may be potentially harmful information. Will someone give a good scientific explanation why though? I'm curious to learn more about batteries. However, this is how I've been draining my battery and it is a damn good method if that's what you want done.
Mine says 2.6.32.9 no matter what kernel i flash. Try flashing it just to be sure. I've tried all the ROMs and they all drain hard until I add the stock kernel to them. Though now a days a lot of ROMs include the stock kernel (Macnut and Axura for sure do). The problem with all the custom kernels is they dont seem to let the phone sleep so when your screen turns off the phone keeps draining as if you were using it. Stock fixes this so when your screen turns off barely any power is used. I
But like I said.. reflash it just to be sure.

to the OP, try axura rom. i have tried all the TW, eugene and axura. axuras the only one who gives me a good batt life

Thats because Axura uses the stock kernel

Android is based on Linux and uses the Linux kernel as a base. The Linux kernel your phone's kernel is based off of is version 2.6.32.9
ok.. think I loaded the stock kernel up.. lol I'll let it run for about an hour and see what kind of CPU numbers I get in idle.
Thanks again for everyones help/input.
FYI.. just put it in flight mode for a bit and CPU usage dropped down to almost 0%.. I'm not understanding why it cant do that when the phone is idle.. ahh well.
Idle for an hour should lose no more than 1% battery depending on how much stuff you have polling and updating.

That is just the version.
That version won't change like the baseband does.
I've been trying different ROMs and kernels on my Fascinate. I haven't run into any problems that I counldn't fix, though losing my Verizon voicemail took me some time to figure out, but I did. I've tried different ROM/kernel combinations trying to get the best performance with the longest battery life. So far I would have to say the best battery life came with Super Clean v.9 with the StupidFast v1.54 kernel. It also performed well. But I like the looks of the Super Dark ROM but I can't couple it with a kernel that gives me really good battery life. I've tried several of JT's non-voodoo kernels and StupidFast SV and UV overclocked kernels, the overclcoked SF is giving me alot of FC issues. Unless someone can give me recommendations I guess I'll go back with Super Clean and Stupid Fast SV.
Personally, I found DJ05 and SirGatez BlazedEclair kernels to have incredible - of course, after the the battery is calibrated that is. Almost no loss of battery during the night or during standy, and the amount of battery used in applications has been the least with the BlazedEclair kernels. BTW, I do use the Voodoo5 versions of the kernels, haven't tried nonvoodoo.
Well I finally did it last night. I had tried many ROM/kernel combinations to get the best performance with the longest battery life. I love the looks of the Super Dark DJ05 ROM but I couldn't get a kernel to go with it to give me great battery life. I'd take it off charge about 6:30 am and it would get down to 30% usually by 12:00. I have been rooted for about a month and have been reading about voodoo alot. I finally downloaded a StupidFast voodoo kernel. It went perfectly and the battery life seems to be better. My question is should I run SetCPU and if so what settings should I try? Any other kernels I should try also? Can I just flash a new voodoo kernel over the current one? I've read that you can and I've read you've got to disable the lagfix before reflashing a kernel.
I have found a combination for my phone, may not work on all phones. I am rooted, running voodoo, running jt's 1134 voodoo kernel on the Super Dark ROM. I was looking for performance with long bettery life. I flashed the kernel about 5 hours ago and I had 62% battery. Now I'm only down to 48% after internet, recording video at a birthday party, and a few calls. That's much better than any other setup, voodoo or not. I'm also running SetCPU set at 1000/200 with screen off profile set at 400/200 to hopefully save bettery life when it's asleep. FWIW it's scoring 1688 quadrant. What does everyone think? Thanks for the insight.
TBH with you I have been wanting to try out voodoo myself but I am still not entirely sure what it is. I know it is a different type of kernel, but thats about it.
I really wanted to know how well does 2.2.1 stock firmware such as JS5/JS3 performs nowadays.I read alot posts saying that lag fix is no longer needed in 2.2.1..how well is the battery life without applying the lagfix and kernels? and the performance? Is that really ok we don't apply lagfix or any other kernels on 2.2.1 anymore? so for those who never apply lagfix or kernels on 2.2.1..would you mind sharing how well does your sgs perform? in terms of battery life and performance? Is the sgs on stock 2.2.1 performs not much difference from a lagfixed sgs?
Completely stock 2.2.1 JPY on XEU. No lag at all I can notice except for the Market which for some reason seems to hang for a few seconds but I presume that is the app as it doesn't happen anywhere else. Battery last 1-1 1/2 days on full charge light to medium use.
Stock JS5, flashed with Odin, lost all settings in this progress, but it works perfect since 4 days. Battery life and overall performance improved over JPY.
Personally I see no need to switch to a mod/non-stock firmware. Also, I only needed root once, when the gSensor calibration data got stuck and I needed to delete a special file.
2.2.1 JPY - JS5
On 2.2 (stock) it was a touch laggy, so I used OCLF.
On 2.2.1 its actually faster with OCLF disabled and uninstalled, particularly so on boot....
This also means no worries when the OTA 2.3 update is available in some 8 weeks, no possibility of losing everything in a crashed filesystem incompatibility problem.
YMMV

OCLF is DATED man. Never even touch it with a barge pole. For those looking for STOCK PDAs to use, check my signature.
PS : I personally feel Modded ROMs are overstuffed & way too bloated. But that's ME.
PS2 : Many people use Modded ROMs for their ability to change the top bar with battery mod & some such things, I use ADWLauncher & with a flick of my finger, the top bar disappears.
Use BattStatt for percent charge remaining & charging mode display, you have hundreds of apps & widgets to help you out.
I feel that you don't need custom rom or kernel's if you are satisfied how it works and looks.
But if you want more speed and less battery drain you need a custom kernel.
Also if you want to change the look you also need to use a custom rom.
People that's say you don't need lagfix has never use them or can't see the different.
With the latest stock firmware the gap between them has shrink, but it still different.

I use stock 2.2.1 JPY and it's fast enough for me, no noticeable lag, basically if the phone was released with the current ROM the term lag-fix wouldn't have existed. I use LauncherPro with other battery apps which provide enough customisations for my needs.
I previously used voodoo on 2.2
My observation, made me believe that there is no need to have any lagfix with 2.2.1, everything loads fine and smooth, a big change. No problem with market even. Only lag, I experienced was because of app but not OS problem.
Battery life: with light use, I get 2 days complete and with medium use, I get 1 & 1/2 day with full (I don't how to define it but I did a lot with phone for example played game for 2 hrs.) use its last at least 12-16 hrs. I did many tests so I am sure. Not bad though.
If you like how it works then there is no reason to change that.
Its big different from 2.1 when I did get the phone. You needed a lagfix then.
But now the phone is good without it.
But you still get alot more out of the phone when you start with custom stuff.
You cant ignore that and when you have crossed that line you never want a stock phone anymore.
But I have full respect if you don't want to custom the phone..

Used lagfix with 2.1. Didn't bother with lagfix under 2.2 and it was horrible. With 2.2.1 though, it's faster than with the old lagfix. Running stock 2.2.1 now.
As has been said, lag fixes wouldn't have been invented for Galaxy S if everything worked as quickly as it does under 2.2.1. They finally got it right.

I've been using 2.2.1 for ages, am on JS5 now. Recently I install Supercurio's Stock + Voodoo kernel that just gives the EXT4 lag fix without everything else. The phone IS quicker with EXT4, though battery use seems a bit heavier, I'll need a few more days to confirm that. Overall I was happy with stock 2.2.1 and only installed the mod kernel out of curiosity to see what EXT4 file system would do to the phone. I'm in two minds whether to keep it or remove the EXT4 and flash back to the stock kernel. I'd say it's up to you, if you are happy with your phone then keep it stock but if you are at all curious, try out a modded kernel to see, you can always go back to stock if you don't like it!
hmmm..so it seems performance did really improved alot since 2.1...do u guys thinks its ok if applying speedmod by enabling all the tweaks but without changing to EXT4 will have a batter battery life as EXT4 is well known for its battery drainage. As I know speedmod has lots of tweak including battery life tweaks.but the thing is it has sharpness fix and 500hz.i believe it sure use much more battery juice than the stock 2.2.1, well maybe a little? lol..so how do u guys think about this? [stock2.2.1+speedmod tweaks,without lagfix vs stock2.2.1(purely stock)]..lets take stock's battery as a margin bcos i think stock will have the best battery life isnt it since no mods at all.
I feel lagfix (ext4) is still noticeably faster than stock rfs. You notice it much more if you disable all windows animations (i.e. without window animations masking the real speed)
My phone is on JPY 2.2.1 with no mods at all, although I had lag on 2.1 there is no appreciable lag on my present standard set-up.
I normally charge my phone overnight, every night, but when I forget, which I do at least once a week, I end up with 42% battery at 08:00 on the second day, after 24 Hrs, which lasts me until the evening, say 18:00 when I recharge.
The only exception to that battery life, is if I am in a poor signal area for 2g, when I sometimes have problems getting 16hrs out of a charge.
mine is stock 2.2.1 jpy with a few system apps removed and a few custom system apps (ie customized framework.. with icon changed i did myself) and a customized version of twlauncher with transparency and landscape enabled.. also modified wifi with adhoc enabled..
i was not using lagfix but my other i9000m phone before it died/flakey again needed lagfix so tried it for awhile.. (this one is i9000t)
now using speedmod kernel and tried the ext4 lagfix and it is very stable and slightly faster.. same benchmarks about 14 linpack and 1340 or so quadrant. but things are slightly smoother and certain things such as bring up the entire app list or gallery is definately faster (bsically io bounded things)
been using it for over a month with no adverse issues.
flash JPY with odin....very smooth with quadrant 1100 no lag fix needed. battery life almost 2 days with moderate usage. No problem at all until now!
does lag fix improve gaming performance? no?
I'm running Com Rom 1.3, and was looking for some kernel recommendations. I'm running the kernel that came with Com Rom which I guess is OTB, I never flashed OTB 1.4 so I don't know if I am running it. I was thinking about PeanutButta Jelly Time but was wanting some reviews on it first.
I am running PB&J 50 but found the smoothest is 100 and i will most likely flashing back to that later today.
But i could never get ComRom to run with OTB 1.4 so i cant really compare.
Good Luck!
what are you looking for? with otb you can customize your clock speeds/voltage settings to maximize speed or battery life. with pbj your locked into set values.
I know it doesn't get talked about much, but I've always gotten my best results with times_infinity's ComaVolt kernel.
Im looking for the best stability, speed, and battery life
Sent from this EMT's Fassy runnin' ComRom!
OTB 1.5 running great for me.
Personally, the kernel in ComRom works great for me,so that is what I use. As far as other kernels, I have used some versions of otb which was good... but you have to find the right configuration for yourself.

Amen. You could get 1,000 replies on this and you will eventually get recommendations for every available kernel. Everyone's set up is a little different, and there are even differences in each phone as they leave Samsung. The only way you will know for sure what works best on your phone is trial and error on your phone. A lot of people are having great success with OTB 1.5. For some reason on my phone with my set up on Comm ROM 1.3 and any of the OTB kernels, I get sleep of death. I'm using ComaVolt and having no problems. That's just unlucky for me that I can't get the OTB kernels to work.

Same for me. Every OTB I tried give me SOD after about a day a half and I tried all sorts of different voltage combos. Comavolt game me SOD after about a day. I'm trying PB&J now to see how that works. I'm starting to think my phone does not like any UV kernels at all. Hopefully I can find a setup that works.

I have found the OTB kernels the most stable because you can choose to uv them or oc them, but you don't have to.
My own personal experience is that my phone can be uv'd to a point and then it gets flaky. I can nowhere near uv the way some others can... But I can experiment.
My current setup that seems to work best is OTB 1.3 with uv'd at least -50 everywhere and oc'd using 1200 as the limit at stock 1000 voltages. Gets me quick and responsive phone and seems to give great battery life (because most of the time the phone is spent at the lower steps where it's moderately uv'd).
I've tried imnut kernels and keep coming back to the OTB 1.3 (because 1.4 and 1.5 seem to break other things for me). For me, EVERYTHING seems to work on OTB 1.3.... BT, WIFI, everything...
But like others have said, YMMV. Good luck!
Well the -50 mv PB&J kernel is a no go as well it looks like. I got the SOD already. I would really like to UV, but my phone doesn't like it.
Wow. Just switched to peanutbutta jelly whatever -100v. Battery its invincible, and performance shows no lag. Literally my battery has only gone down about 3% in the past few hours with wifi on and light usage.
Try the comavolt kernel. I just flashed it yesterday after replying to this thread and have been running it nonstop since then without issue.
Battery life on comavolt is ASTOUNDING. I mean like shockingly good- on my phone at least.
I tried comavolt and got SOD on that too within a couple of hours.
I went with PnutButta Jelly Time 100, I like it, great battery and stable.
the otb kernels seem to work the best for me.
