Uf, you should consider then some other OS. Not sure what we can run on the galaxy though. Search the forums. (maybe ubuntu?)
I know you mean the process . But this is seriously funny .
There was a thread in which this process jumped up when using screen filter. Check that out.

You are using an unreleased version of Android which I don't think has even been included with phones yet and you shouldn't expect it to work well.. It should come as no surprise that the battery drops like a brick. There are probably many other bugs too. It doesn't mean the official copy is buggy, and it doesn't mean the final version of Samsung's copy will be either. It's like stealing a bike which is only half assembled off an assembly line and complaining the seat is wobbly.

Come on Auzy . That has nothing todo with "unreleased" besides http://goo.gl/FnGjR
This is the thread I meant http://goo.gl/AP6z3
I got 58 hours standby(2:20 Hours of display, all network on) that ROM is so far BEST for battery LIFE.
An a side note to you. Please check how many bug reports you got on eclair, froyo and now gingebread and then state those "facts" about unofficial, unreleased and many bugs.

What happens when i deleat the Screen filter app?
And how can i deleat it?

I had the same problem as yours. On my first install, Android OS eats up most of the battery that my phone could not last for a day in a single charge.
But when I installed CF-root kernel, that issue was gone and Android OS is back to normal.
I suggest you try to flash the original kernel only using odin and see if it works. If not then try to install CF-root kernel.

if you didnt install it, you dont have it

Okay than the problem comes From another reasen :-(

In order to fix your battery life, there are a few things you can do to improve it:
1. Recalibrate your battery:
- Charge it till it is full;
- Completely drain it, till your phone won't turn on again;
- Completely charge it;
- Go into CWM -> advanced -> Remove battery stats
And done!
2. Make sure WiFi and GPS are turned off when you're not using them!
3. Download SetCPU. Enable profiles and set following profiles:
- Charging: min 1000, max 1000
- Screen Off: min 100, max 200
- Normal: min 100, max 1000
4. Download Voltage Control and set 100 MHz to -150 mV.
Your battery life should improve now! This fixed my battery problems on Froyo 2.2.1 atleast

Without reading wha the guy adviced up. My Android OS process spiked up too. And it got so far that it froze the phone . Had to take the battery out.
It seems it was done either by a game (Cordy) or SetCpu I ran it but not allowed it in SU. Android OS and the Events ate it

had the same problem. seems to be a wifi issue, even when wifi is off. i think i fixed it by setting the wifi-sleep-policy from "never" to "sleep when screen off". don't know why but it helped me. didn't even lose 1% in the last hour and Android OS went from 82% to 71%.

Okay thank you i try it, but i have this problem also if wifi is not on.

i know i did too. but by changing the policy the problem disapeared. dosn't matter if it's on or not.

Ad-hoc needs a lot of power, always at 80 mA, this is Wifi very weak.
Can I use wifi from 2.2.1 to 2.3.3?

Hi i have read to fix the problem do this:
System settings - applications - Applications - (rider) ALL software update - "delete data"option.

I really look through any more.
My battery is now 2 days was okay and now it starts again at the the Android OS will look into the level I like the battery is eer.
The only thing I've done is I've added in the preferences WhatsApp account so that my contacts will automatically update itself.
But I looked to the APP watchdog and think nothing which time the battery.
It says only Android system and mmmcps?

use ti backup to made a back up of "software update" and samsung account 1.0" then freeze or force delete them. never had the bug since

uthink that Bawdz, but every time u play a game, the android OS will be back sucking up ur battery power

Move to JVO firmware
Had similar issues on JVK. For no reason the battery drain was much worse than on froyo. Installed JVO firmware and the problem went away!!

me too
cyanogen, juwe, darky, stock rom if base on 2.3.3 same meaning
i try pull-push battery, power off-on,stop auto update noting to change - -"

[Q] Having fast batt drain after installed Oversome 3.1.1

Dear all,
I just upgraded my tab into overcome 3.1 from my initial GB 2.3 . The reason why i started to discover some issue on my batt usage is within 2hrs it will take off 20% of my batt when i fully charged in the morning.
After which i check on my application - batt use - it show "display" is at 92% on the top and android system is at 2% at the bottom. Whereby when i use GB 2.3 rom, it will show andoid system is at 80~90% and display is at the bottom of 3%.
(Note: i have even set my display to the lowest and set it to Auto mode, some of the un use application i also shut down)
I have started to think should i change back to GB 2.3 or is there any brother outside can advise what should i do to change this situation. Hope someone can help me on this ..... Thanks in advance.

dear all, after further confirmed, my colleagues also having the same problem as my, I was wonder is there a bug in this version as em not sure why the consumption of the battery was so high after installing overcome 3.1

First of all, old ROM had a bug, battery usage was displayed wrong. That is fixed, but they are now working on R2 version of kernel (Reverted lowmemkiller change which may have been blocking kswapd0 from sleeping, resulting in battery leakage).
This last kernel has a new ROM as it's base, so you have to install new ROM first and then full wipe version of kernel.

Good to hear I am not the only one.
Hermes was an awesome rom concerning battery stamina. I hope the guys from Overcome will make this R2 release just as good.

thanks for your quick response.

The latest version of the overcome kernel is pretty good on battery life for me.. the only thing that seems to be wrong is the reported charge level against the battery display level..
Even after calibration its still way off (20%)..

i think you need to perform a "wipe on batt" in cwm maybe can help. Anyway i also discover that my tap below 4 buttons occasionally the light will be blinking on and off during at the standby mode, i belived this also can cus some batt drain off too. Anyway, most of the people are concerning about batt duration especially devise such as non-detachable batt. For me, i use my tap outside most of the time especially during business trip hangging in the train station or airport.... Well, i think we appreciate the overcome team and the rest of you guys to test it out and gain feedback for improment.... cheerss... and Selamat Hari Raya to all muslim people ya.

did you try the tweaks here re: Battery Recalibration and Reconditioning…
http://p1000.teamovercome.net/?page_id=68
and do note that:
battery wipe by itself would not immediately “improve” your battery life. IN FACT, during the first charge cycle after a battery wipe, you might notice a slightly less than optimal battery-life! This is because, the stats have to be rebuilt, which is why after a couple of FULL charge cycles after the battery wipe, when the stats are properly “repopulated”, which is when you’ll see the difference.

yes, i have did that after going through the forum, and today is a second day after the wipe, but i would recognized that if you put the tab in Normal stanby mode, the batt will drop about 1% in about 4hrs since i have started to monitor this morning... well, i will continue to monitor aand post it again. thanks for your advise.

my one on overcome 3.3.1 seems to last at least 1 hr when the battery notification show 0!!!

I have tested my second days after batt wipe, it seem that if we put at standby mode the batt really better then earlier versions, i can notice that last night was 26% at 2.30am and this morning waikup at 7.15am, the batt indicate 24%. (Note : my wifi is on, except BT and GPS is off).
My conclusion for now is that the OC 3.1 batt life is ok and even better when it was in standby mode, however whenever any application for example browsing internet or starting reading news, the batt will start to drain off like 1% every 3min (my estimation point of view).
Hope the OC team can help to improve from here OR the nature of this OC 3.1 is normal on this circumstanses. Cheerssss....

[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.

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.

Team ICSSGS RC4 problems, looking for solutions

I´ve noticed a few bugs, problems in this new version of ICS. If anyone knows how to solve them I would appreciate your advice
So, here is what´s bugging me:
1. Screen sometimes go greenish for a second or two when there is a lot of apps running and when I quickly turn off and turn on the screen (it happens when the screen goes on, that moment)
2. Overclocking seems very unstable!! ..when I OC my phone (with NStools) and do some things..after a while, it freezes and reboots. On RC3.1 version I could overclock to 1.46GHz and play games and it was very stable!
(I think they changed voltage and because of that it´s unstable, but I´m not sure)
3. When system reboots (after crash), it reboots in clock work mode -.-" ..why can´t it reboot normally, into system?
4. It´s not really a problem but, does anyone know how to remove unnecessary home screens or add them back? Is it possible?
5. .apk files can´t be sent trough bluetooth .. (message: This Bluetooth device or computer cannot process files of this type. )
Other than that I would say this version is almost perfect, flash works in browser, effects in camera, USB mass storage ..works very well.
I was on Doc´s ICS teamhackungs based rom before this one (and after RC3.1 )..and I noticed that battery life was terrible even with juice saver apps running.
I hope this one is better.

Actually RC4 has been pulled because of a Wifi issue
I flashed it last night before it was pulled, I flashed over Onecosmics 2.11 no wipe, and my wifi its working normal.

It is a great rom, I hope they can fix those minor issues.
Battery life for me has been just OK on 2.11, I have to give RC4 the 3 charge cycles before any judgement.

I've just noticed that battery life was reduced constantly in last 3 days, now battery doesn't last 12 hours, but it's the first time that happens!

Yes, so did I ..just before they pulled I downloaded the rom...I was on Doc´s ICS..but I flashed with Odin JVT 2.3.5. GB ..rooted with CF-root and then in CWM flashed RC4 ..my wi-fi was having problems but when I updated WiFix manager it was ok then.
Yea, I couldn´t agree more, if they fix those issues it could be it..the final version (without any bugs). Lets hope they do it soon so we don´t have to wait too long
btw. I was thinking, could we solve these or at least some this issues by flashing another kernel??
@Giuku :I´ve noticed that too..even though I´m not OC now it still drains a lot..or my battery become weak (It´s 1year old) . But that is not without a reason..I did put her to her limits (and my phone) by playing games so much that my smartphone reached max temperature of 60°C and then cooling it in 1min to 30°C and less.

[ROM]Cyanogen Mod 6.3.8 - Massive Battery drain

Hi all,
I'm and oldbie that has installed allmost all the roms that avilable to milestone.
last one was ICS from kabaldan, wich i find it working very slow..
before i was at CM7 for allmost half a year and it was working good but not fast as all mantiond here..
than i moved to cm6 6.3.8.. Perfect Speed allmost, 0 stucks, stable and look nice.
but the batterry is draining like no tomorow..
i found myself with 10% Bat on the late afternon without and spesific stuff..
any sagustions?
thanks :>

Try turning off 3G in Mobile Networks. I believe this thing fixed this problem on my phone.

but when i was at CM7 the 3g was working non stop ..
why is there a big differance?

I have no idea, honestly. Did this fix the issue?

Nop this dident fix it..
the battery usage is on display (?!) and android OS (that i btw removed a few of apks that was causing battery drain on the android os menu)

Install CPU Spy from the Market and see whether the device is going to deep sleep or it's staying at the min frequency.

so ive been at this all day reading and searching these forums with no luck.
i have a droid one, running 2.2.3 FRK76, bought the phone used. says it has kernel version 2.6.32.9-g68eeef5. no clue what this is.
have tried to root with superoneclick with rageagainstcage option clicked. also tried the one click some one had posted on this site in one of the forums. Sd card is unmounted. debugg mode is selected. and i cant get past first time it says waiting for device. what do i do?

Also try better battery stats and see if an app is running a lot. Different phone, but I had save problem and it read google maps check in service. Also did you calibrate your battery it helps
