[Q] Battery still draining quickly - Galaxy S I9000 Q&A, Help & Troubleshooting

Hey guys,
Since changing firmwares and kernels etc; my battery has been going flat even quicker then at stock. I can understand this seeing as I have my device overclocked to 1.2GHz; but the thing is that it's draining WHILE THE DEVICES IS NOT IN USE. EG. While it's sitting idle with the screen off.
Now, I do have facebook/twitter/weather/news set up to refresh, but only every hour and on Twitter ever 3 hrs, so I don't think this is the case. I also have a profile set up on SetCPU which when the screen turns off, it sets the CPU to Min: 100MHz & Max 100MHz.
On the Battery usage screen it looks as if the screen is using up ~70% of the battery.
Here's my setup:
Samsung Galaxy S GT-I9000
I9000XWJM8
SamSet 1.9f
1.2Ghz OC /w Voodoo 4 & BLN

Hey
I had the same issue with my SGS. My setup was stock JF3 plus voodoo lagfix 3.0. Phone was fast but battery drained very quickly, and didn't stop when it was on standby. I suspected the custom kernel that was included in the voodoo lagfix.
I have since flashed JM8 to my phone and used the lagfix found on xda under
[Voodoo Lagfix] : Play Voodoo with STOCK ECLAIR kernels! - FINAL
which is like voodoo lagfix but with JM8 kernel instead. I'm now enjoying a fast SGS with very good battery life.
Cheers

Thanks for the reply.
It could quite possibly be SamSet 1.9f doing the draining; but I'm not sure.
I don't think I could go back to stock after using SamSet anyway; that thing is just incredible

I might have to give it a try. Although I still stand by voodoo giving you the battery issues.

They say it was Version 3 of Voodoo which was giving the battery problems - wait, that was the OC kernel wasn't it?
Not sure; it should be fairly noticeable to everyone when the screen off function is not putting the phone in stand-by mode!

When I had the issues I used Voodoo lagfix 3.0 which is a part of Voodoo beta 4. They said there were battery issues in Voodoo beta 3 (this contained Voodoo lagfix 2.1). I have read a lot of reports of people winding back to Voodoo beta 2 and not having battery issues.
I think all the Voodoo versions have all used OC kernel.

JM8 and voodoo combined cause battery drain. Use other lag fix or firmware...

Yeah, I noticed a significant increase in battery drain after installing JM8 + Tayutama's 1.1 ROM w/ Voodoo.
Although I really like the increased speed and Tayutama's add ons, the battery drains almost twice as fast compared to the average during my previous month using the phone with stock I9000DTJG4 firmware, which to me is pretty awful.

there is a very big difference in battery life time. my setup us also JM8+Voodoo4.. I charge my foon every night. and when i'am eating dinner the battery is bleeping.. and there is actualy no active use..
I like the combination of JM8+voodoo.. it really feels great.. so what can we do..?

Well, I use JM8 with RyanZa 2.3 Lagfix and I don't have any problem with battery life.
Using mails (push), Games and MP3 about 2 or 3 hours per day, and battery is at 60% at the and of the day.
Not bad isn't it ?

Same problem here , i have JM8 with Tayutama & Voodoo lagfix , my battery drains like hell ^^

hmmm i noticed yall talked about a fast battery drain using the voodoo lagfix
could it by any way be the latest 1 (V4 beta) ? coz on the website and i quote
" Bugfixes :
The battery life issue introduced in beta3 is resolved. CPU was locked at 1GHz, which some people saw as a feature (snappier Phone!) but in reality this was a bug, sorry guys "
so V4 beta should be a fix and not suck up much battery like V3 beta
as for myself my phone was a First Gen i9000 international version and ever since i got my phone it never lasted a full day of use....
except for when i changed 3g to 2g , disabled the internet apn , disabled the auto sync , pretty much disabled everything and went very low on the screen light and yet ended @ 10-11 pm with 2% battery life with a max talktime of an hour thruout the day and screen was off almost all of the time except when viewing sms's , yes it lasted a full day to me but i sure hate using my phone that way, pretty useless T_T

Thanks for the suggestion, but Tayutama's 1.1 ROM is supposed to include beta 4.
I've got the international version as well and usually got 2, sometimes 3 full days usage with the stock firmware (with about 2 hours of browsing, 2-3 SMS's, 1-2 phone calls and 1 hr of music a day). I did my best to maximise battery life by switching my background wallpaper to be mostly black, and the phone set to minimum brightness
Ordinarily I'd be down to about 60-65% battery life after a day of usage. Using JM8 and Tayutama's ROM I'm down to 22% after 1 day...

It's really weird. Just a day or two ago, I reported having battery issues with the combination of JM8 + Tayutama + Voodoo b3 lagfix only.
Today, I unplugged my phone in the morning (approx 08:30) after an overnight charge, rebooted it just in case, and have been using it quite heavily. Lots of 3G data and Wi-Fi (I hear Wi-Fi is a culprit in some cases), a few phone calls, SMS, and music. I have brightness set to low, and black backgrounds where possible.
It's now been more than 12 hours of operation, and not once have I had the rapid battery drain and excess heat that I had complained about. Or wakelocks, now that I think about it. Remaining charge is roughly a third. I actually don't mind; I'm of the belief that smartphones need a daily charge anyway.
But the heat problem. It didn't happen today. I don't know why. In fact, I don't even know what caused it. I'm glad it didn't happen, and hope it doesn't again, but it's just very very weird. :?

With JM8 (Tayutama Edition v1.1) voodoo + OC my battery draining very very quik.
I have applied update.zip "[Voodoo Lagfix] : Play Voodoo with STOCK ECLAIR kernels!" and now batery life is very good.
P.S. = to applay update from Tayutama voodoo to STOCK kernel + voodoo LagFix i don't disable lag fix before or other ... just update kernel over it ... of course i lose OC but now my SGS work like a charm and batery life is very very good

I just flashed back to stock from Voodoo 3.0. If you go to the dedicated Voodoo thread, you'll have people complaining about the battery life while others try to dispel the rumor that Voodoo is the cause. I fully believe it's Voodoo. Since flashing back, I have the exact same setup I had before {done from scratch} while using OCLF instead. Battery is fine now.

man this is almost the same behavior i have with my phone. It can last one day (around 25-26 hours) only when i disable everything, put the brightness to the lowest level and pay attention to the apps running in background, this with low/moderate usage (2-3 hours display on, few calls or sms). My phone drains battery as hell.

I guess there is some Calibration Problem when you are flashing a new firmware. Try to flash a new firmware with full battery.

Just went and disabled my current Voodoo b3 and installed the Stock Kernel Voodoo... (Checking each way with a Quadrant bench.)
My battery suddenly went from 26% (curio's Voodoo) to 65% (stock Voodoo). wtf. :s
I totally need to refresh battery stats...

I've noticed a couple of times that my battery is around 40% and I restart my phone and it jumps to 75% w/c I find strange, also 100 to 70% seems to to drop so fast and it stabilizes at ~60%

[Q] Battery Life on Froyo (Dream/Sapphire)

Simple Poll.
Have you seen a decrease or increase?
Someone can explain this battery drain?
in a lot of roms based on 2.2.1 there is a big battery drain, in some other there isn't.

Reboot after unplugging from USB and battery drain is gone. For further improvement install SetCPU and reduce min/max frequency. I am getting more or less the same lifetime as with donut ROMs.

OK I have done.. but the problem is that when I use it 3 o 4 minutes (for example I install an application using a file explorer, then I read a message and then I come back to home) m battery get 5% lower...
In standby I lose 10% in 6 - 7 hours (I think this is normal).

I am currently without a computer therefore immune to this USB bug. I flashed CM6.1 to this and the other g1 and both suffered substaintial amounts of battery drain so I nandroid restored back to CSDIv4 and still the lowest frequencies and settings did little to combat the descending digits. So I tried this...
Recalibrated my battery
Flashed SuperWipe.zip
Reboot
Flashed SparksMod's latest
Reboot
Wiped battery stats
Unplugged...reboot
Battery lasted 23 hours the first day never seen anything like it.
Lifes great.

I'm using TMUS-G1-Froyo CM6 remix..
and I'm using the new radio with +14mb.
The rom flies but the battery go down too fast.
I'm using setCPU with 256 - 528 mhz while screen is on, 122 - 256 mhz while screen off.
If I go to battery use in settings I see
Cell standby 45%
display 28%
phone idle 22%
android system 3%
I don't think is normal... cell standby is the battery use by cell radio..
I wonder if the new radio give a big battery drain..

I got real excited when I heard about the new radio and hboot even thought that its exclusion was the source of the the battery issues. Haven't been able to try it as I'm without a up-to-date PC at the moment.
It would be real nice if I could find a seasoned dev who understands battery consumption. I thought the kernal was the main culprit but I've tried two different roms with the same kernal and one has notably better battery life than the other. So confusing.

I can't use my phone with this battery drain...
I will come back to official android OTA-AOSP 1.6.. with +14mb.
So I'll test if this kernel with 14mb is a cause of battery drain.
PS: I'm not a lover of rom customizations.. I think the official roms are the best.
The other are all too heavy. I'm not a fan of cm kernel, that is too heavy for g1.
I would see an official OTA 2.2 without customizations, so every one could customize as he want, and if he want.
PS: OK I flashed AOSP 1.6 using ezBiff_kernel to have 15mb (cause I have new radio and spl, so I can flash roms only using this kernel).
Result: my battery life is similar to froyo 2.2 roms... so the problem is:
1) Kernel? (ezBiff_kernel is based on cyanomod kernel... ... ... heavy as death)
2) New radio/spl?
3) My battery (I don't think so.. it's new battery. I buy it 2 weeks ago and in the beginning it works so well.. but then I flashed new radio/spl and new kernel for 15mb..)

Come now.. the cm pershoot kernels are super optimized so they don't collapse under the heavy as death rom that is usually on top of it..
I get mixed results with that kernel between testing and feedback.
A test phone can idle on wifi+2g for days on the stock g1 battery even after a usb unplug.. but on more common use with syncing services its not performing as well as I'd like..
Some of it is fixed with less swap/compcache or changing clock speeds 122/480 for most the speed but lower voltage levels. Also the interactive governor may work better.. I'm testing these ideas if results are good my next kernels defaults will use them.
Cm/pershoot have some interesting new power management code from other htc devices.. So hopefully soon all will be better. (I merged most of it to my kernel but there are some loose ends.. works well untill the phone locks up.. so no public release yet)

Ok sorry I talk without knowledge. I really don't know the effect of the cm kernel. I only know that all roms based on cm release, with cm kernel, are so heavy and slow.
I like your rom (2.2.1 AOSP) and I love your new way to get 14mb.
But I have this orrible problem. My phone has a lot of battery drain when I use it. With screen off, no problems.
I have never used swap or compcache in this days, and I also try different clock speeds (not over 528mhz).
The result is that when I unlock my phone, I go to settings, I see for example 95% battery. Ok, I return to home, I open a message, I return to home, I open contacts and I scroll some contacts without make calls.
Then I come back to battery settings and I see that is 92-93%..
in 2 minutes of soft use.. I think this is impossible. If I open stupids 2D games... ahah in 5-10 minutes my battery lose 10 - 20%.
I remember 1 year ago, with 1.6 (no cyanomod) my battery was good.
Now it isn't (I have a new battery).
Today I flashed aosp 1.6 with your kernel for 14mb (I have new radio&spl) but nothing... I lose a lot of battery percent as in froyo.
So I think problem is or battery calibration, or something to wipe, or cm kernel, or new radio&spl + your new kernel...
Now I'm recalibrating battery (is at 1% from 2 hours, I'm not using it.. ) then I will recharge for 8 - 9 hours and then wipe battery state, but I have done this process a lot of time without a benefit.
I'll try to remove the new radio+spl (so also using standard kernel) if my battery continue to lose percents so fast.
I'll keep you update on my "story".
PS: Sorry for my bad english!! XD
OK.. after a day of low discharging and a night of 8 hour of recharging, I wiped battery states, I wiped data-cache-ext ecc... I flashed aosp 1.6 and ezbiff kernel..
"battery drain" continue...
I will try tomorrow to reflash death-spl and old radio..
BTW, is normal for hours battery 4v at 90%?
On the back of the battery sais 3.7v... I thought 3.7 was the voltage for 100%
Update
I know this thread is a little old, but I ran into this problem as well. What I found was that the official US radio (2.22.23.02) used considerably more battery than the international one (2.22.19.26i). The other thing I noticed is that switching to "use 2G networks only" in mobile networks settings and disabling data over mobile drastically improved battery life.
I also noticed that wifi used a fair bit of juice so my recommendation is to disable wifi if you're going to be on the go for a bit, and disable data/3g if you're just going to be hanging out in the local webcafe, your/a friend's house, or some other location with wifi access for a while.
If you wanted to be ambitious and cared enough you could write a script to use as a shortcut on the home screen to do the swap automatically (detect which setting(s) are enabled and swap them to the opposite).
With those changes, you should get much better battery life. My thoughts on different Froyo flavors is that possibly different builds have different settings by default. Cyanogen comes with data and 3g enabled by default so this will quickly suck out your battery if you're running your 3g, 2g and wifi antennas all at once.
The stock build (1.6) got about the same battery life as I'm getting now with those settings applied. With either build, having all antennas on all the time will drain your battery very rapidly. Being a little more cognizant of the settings (perhaps you also had it set to 2g only on the stock build) you're using will significantly improve your battery life. And when I say significantly, I mean night and day (but the antenna version definitely does also make a difference... at least in my case).

[Q] CM6 vs Chronos Froyo Battery life

Hello,
Which one has longer battery life? From what I read, Chronos Froyo has longer battery life and also it's more responsive? Why is that?
Can CM6 use the same code as Chronos Froyo for speed and bat life?
I think it depends on overclocking.

I use HO!NO ROM for the CM6 and this weekend i realized that i was 22h without recharge it and was with 80% Battery. No profile set.. no Set CPU... Mobile Data 100% ON!!
I simply can´t understand, why every one has different battery life on same ROM. I know it depends on usage etc. but I´ve heard that HO!NO has huge battery drain
Battery performance is based on how one sets up his phone, overclocking, wifi / 3g usage, media usage etc. But on the same setup , cronos wins.
Ye, why Chronos is better? Isn't base on CM6 too? Or it has it's own modified kernel that's why it's better? Is bat life base on Kernel?

This is based on what exact versions being compared?
I have now tried Cronos for the sake of everyone prasing battery life. I compared every ROM over at least 3 days use and i can say there are no big ddifferences as far as battery life goes between CM 22.11. Froyo 2.0.1 or Cronos 1.6 update1. There is some fluctuation, but nothing too aperent.
Older versions had quite some battery problems, that holds for all ROMs, but now only abaut 20-30% less battery for me on these Froyo ROMs, than on eclair ROMs i had before. For first Froyo ROMs it was like 50% less...
Well, the CM6 on the actual build (0.04) is imho far the best concernig battery-life.
Just a little less good than on SHOLS_U2_36.0 by G.O.T.
Before it was probably Cronos, but nowadays the difference is down to the voltage selected. On Cronos this is lower, so out of the box it should take up less power. However, clock for clock it should essentially the same. The rapid releases of CM6 takes the cake for me
I tried both Cronos 1.6.1 and CM6 25/11, I noticed no great difference.. just a feeling, Cronos runs more smooth at same clock, but they are almost the same!
Sent from my Milestone using XDA App
In my personal experience, Cronos 1.6.1 is currently the best ROM both in terms of battery life and responsivity/relayability. With everything enabled (3G, wireless location service, gmail sync) , is the only ROM that can give me 18 hours plus of battery.

Exactly. I believe both hit battery life with the same tweaks. Then it comes down to the voltage and clock speeds. CM6 should last plenty long too.
Pretty much identical battery life. I use my phone quite heavily so never get more then about 16-18hours. Maybe in long haul there is a difference but not with a well used device.

this. although i haven't updated yet to the latest CM6. my phone once lasts from 2.5-3 days, with minimal mp3 listening and harcore wifi usage.
before the upgrade to cronos 1.6.1 (best froyo to customize) i was using telusV5...
eclair could last even 50 hours without recharge.
froyo is 25 hours at its best.
i use H data always on, gps on, latitude, whatsapp, wireless almost never, i make lots of calls, i read news, play games like angry birds or asphalt5 few minutes.
i tried every combo of mhz and vsel from 1100 74, to 700 46...no significant difference, battery lasts always 24-26 hours.
I use c.m. roms,from about the 10th of november or something,c.m. roms last about twice as much as my stock eclair did,i'm sorry to say that,but if nadlabak didnt exist,cronos wouldnt exist,feeyo is waiting each time for nadlabak to solve each problem and then he will release his own rom.
Whenever nadlabak doesnt publish his work,cronos is stuck...
Nice guy maybe feeyo,but not milestone expert...
I prefer the original thing,wich is more superior in my opinion...

Right but are you comparing it against a tweaked Froyo?
I used STOCK Telus 2.1 back in the day with the Overclock mod at 1000mhz/60vsel.
I used to push email from 8am to 6pm everyday at work. I had terrible reception at work so I would use 2G a lot during the day, but I would always have 30% AT LEAST by bedtime. I go to work at 8:30am and sleep around 12am.
Now I work at a different place, but I got into work at 11am today and left at 6pm. I took a break in the middle to get lunch, but since I work underground, I turn on airplane mode the whole time. It's now midnight (13 hrs since unplugging) and I'm at 40%. I'd say that if I had 50% of my time on airplane mode that's pretty bad. Other than that the other 6 hrs that I was out int he open I got decent reception. I just pushed gmail, sycned Facebook/Twitter hourly and weather every 3 hrs. Not too bad in terms of heavy use. Also I have the 2G toggle on. I just don't see how I'm draining battery this fast.
So in my case Eclair completely dominates. With HONO or TelusLite mod I probably got a little better battery life throughout the day. I dunno. I only had 1 month of work or so during the summer of using those ROMs before I quit and I stopped pushing exchange mail all day long.
You forget something battery gets worse over time. I had very good batery life on Eclair. Now i use Froyo for quite some while at begining veery bad battery life. Now latest releases quite better, but still not there so i went to try Eclair again for a bit and i found out even eclair doesnt have the battery life for me it used to have, battery is just old and its only half a year since i bought. But take this i charge it everydays ometimes more so in half a year a charged it around 200 times. 300times is the number i think battery gets quite worse.
Maybe one of you battery hawks can help me figure out what the major problem I'm having is.
I see people saying they get 24+ hours on a single charge, yet I have a difficult time maintaining 12 hours with minimal usage.
My provider (Bell Canada) does not have a 2G network I can fall back on, so that's one thing that could be causing major drain.
I am using SuperPower (but haven't noticed any major difference there), SetCPU to set processor to 250 when screen is on, 15sec before screen off, wifi off, GPS off, background data off when screen is off, auto-sync off, and data scheduled to be on for 5 minutes every hour.
I use my phone when I commute to check emails, play Angry Birds, and the like, and generally overclock to 700 or 800 Mhz, with 48 or 50 vsel depending.
Using my phone to play a game, check email, or surf the web for 10 minutes can cause it to drop 10-20%, and even when it's totally turned off overnight, if it's not plugged in it can drop to 20% or lower from a full charge just sitting on my end table.
Any suggestions/ideas?
EDIT: I wanted to add that I tend to use the most up to date CM mod, but have been trying Cronos since the battery life was touted so highly. Unfortunately, I find that Cronos drains the battery slightly faster than the 11.25 mod did. Testing the 11.29 version of CM6 currently.

ODD_KL3- best stock kernel !!!

Guys did some one try latest kernel from India
"CF-Root-SGN_XX_ODD_KL3"?
Flash it and check setting scrolling !!!
Benchmark reselt same like every kernels...(linpack 106, quadroStand: 4890)
but the scrolling are so smooth. (im sure is driver modifications)
Probably best stock kernel is here !!
(im on romow v3.5 by mowno)
CF-Root-SGN_XX_ODD_KL3
Not only that I installed the whole Indian software version on my European Note and I can tell you the damn phone flies now, lag is greatly reduced, battery life more than doubled exact same usage, reading around 1000 rss feeds during the day, check email 6,7 times a day and 2 hours +/- of music reading. With old rom versions it did not live past 14/15 hours now it can do up to 48 hours and still have more than 10% left. no heavy usage but nevertheless I can finally use it with no fear as I think a smarthphone should be used.
Exactly!yes I found samething!
Unfortunately I can't see any difference performance wise to the FM-Kernel I was using before (1.4 & 1.5).
But battery usage when idle went through the roof. Loosing 3-4% battery per hour

Fm kernel got some twik (in build prop) witch is making scrolling fast but not smooth at all! !!
But KL3 is perfect....maybe not that snappy but stably smooth...

[Q] I think this is kernel related? SGS chews power ondemand but perfect on standby?

Hey guys n girls,
I am running OneCosmic ICS and the latest FuguMOD kernel (I think Noshur type?) and the phone is running as smooth and as perfect as I want. Better than ever before. The kernel is not OC or UV in anyway it's running as is.
When the phone is left not in use it last forever battery wise. I'm running a good modem to suit my provider etc. I can even be connected to the net with wifi and 3G on (which in any other ROM or kernel prior to this would have drained battery somewhat) and it hardly uses a drop. I am running autokiller, autostarts 1.7.5 (works on ICS) Juice defender ultimate 3.8.8.
The phone battery use is perfect except when I use it. Like if I spend 10min non-stop typing texts it with chew through like 60% battery and it gets really warm. I've done a reflash, wipe yarder yarder yarder all the typical things that they say to do for excessive battery drain. To emphasise this...say at full battery the phone is on and left running on standby it will still be at like 70% after 18-20hours later; but say if the phone is fully charged and I use the phone for 45min it will go down in the red and ask me to plug in to power. That's pretty bad!
Something suggests to me that this could be a kernel issue? Like the ondemand is too savage and the idle is perfect. What would one suggest that I do to address this issue?
I am not going to pass the blame or go flashing other kernels or anything like that....I think this kernel is actually pretty good, but I would like to make it so it is a bit more conservative and not so revved up when in use. I have NStools but haven't done anything with it.
Would someone suggest some voltage values I could put in that will bring the ondemand down but leave my idle as it is?

[Q] [i9000] Team ICSSGS RC3.1 - Battery Life

Hello everyone!
I've installed few days ago the onecosmic's ROM RC3.1, beatiful, perfect, smooth bla bla.
The problem is: i'm seeing so many post of people saying that with full charge, phone can stay alive for an average of 1 day- 1 day and an half (24-36h) with a normal use.
My phone can last 13-14h staying most of the time in standby and it's the 5th cycle so should be "stabilized" now. 1st cycle was awful, 8h (didn't expect anything else), then things got better but i've reached this cap of 14h.
I've tried Fugu kernel at first but i didn't get much improvement so i switched to paul kernel and changed modem too (jvk->jvt).
Still can't reach the dreamed 24-36h, i mean, i don't care about having 2 days of battery life, i would like to use the phone without having to charge it in the middle of the day.
btw nstools installed and set Deep Idle on, which seems to works just fine for me with the paul kernel.
(can't post outside link -.-)
nstools stats:
h*tp://i44.tinypic.com/6duvzb.png
does these stats means it's working?
i'll post also CPUspy stats:
h*tp://i43.tinypic.com/35052qf.png
is it everything ok here?
On standby there's no battery drain effect now, but when i'm using it, i get 1% down every 1-2 min.
What do you guys suggest? do i need to try other kernels/modems? shoud i try to flash again?
p.s. on 2.3.5 stock i used to have 24-36h but there's no way i'm going back to GB, i love ICS.
I used to have 24h of battery life, but I don't know what happened, after a week or so now my phone is draining 20% every hour, dead by noon...
Tried NStools with undervolt, and it didn't change anything.
It's now an useless piece of junk... this is retarded, either i will try reinstalling ICS or im going back to GB.

maybe your problem is caused by an app, or more than one, which are using push notification, you sould try uninstalling some...
Tried undervolt too, i got maybe an hour more.
Update: i just flashed again with RC3,1 and paul kernel. Situation seems a little better, gonna update again after few battery cycles.
What thing is in the battery status menu?
If it is media server: settings-->apps-->all--> Mediastorage-->force stop(dont wipe data)

sure! with the new paul kernel the battery life is better! amd now i'm trying the last glitch...my phone seems to work better...!i will hope to have also a good battery life without hard drain (with didle support maybe it's possible!)
actually, there was a lot of "Android OS" usage, maybe something went wrong from the beginning, the phone wasn't going to deep sleep state when put on stan-by and use more cpu than necessary when active, that must have been the main issue.
As i said, installed RC3.1 again this morning now everything is gooood
Lots of facebook, whatsapp, camera and 1 call, still have 67%. When put on standby battery almost doens't drop at all (checked on battery graph).
I think it's solved
I've the same problem. my battery life sucks...
Now my question. Where can I find/download the paul kernel? I#ll re-flash it too .
And my second question, do the "devil - der teufel" kernel do a great job too?

dunno about devil kernel, i read that for someone is even better than paul and it solves also "green screen" issue that appear when you lock the phone. I'm happy with this config so i won't touch it until RC4
I confirm that ,now, when my phone is in stand-by, battery usage is almost 0.
btw paul's kernel can be found here:
h*tps://w*w.dropbox.com/s/ts8j2o7wuklq9zg
(sorry about the "*" in the url but it won't let me post link 'til i get 10 post -.-)
is also in the first post of the Team ICSSGS rom btw
I have flashed RC3.1 yesterday, it lasted for 8 hours. I was using it heavily to check all the features, syncing the contacts etc. I have drained the battery fully now. Will charge it upto 100% and see how long it last now with normal usage.

thank u
i'll try it today and pray for a better battery life...
when RC4 is out than i think i will try the devil kernel... but until that i think "paul" will make it ^^
Battery Drain
hello everyone - I have been searching a lot abou this i9000 battery drain on ICS. I am using ICS and Devil karnel and battery lasts for around 11-12hrs. My usage is pretty normal. I dont use phone for most of the time but still it reaches to 12hrs mark. If I check battery stats then Android OS and Display (brightness is very low) are consuming most of the battery.
Please let me know if there are any ROM Tweeks or any other way to increase battery time. Or I will have to go back to GB because I hate charing battery two times a day.
Thank you.
