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] MIUI ROM doesnt go to sleep!!

Hey All,
My Milestone running MIUI 1.6.4 doesnt go to sleep when I turn the screen off. This is leading to poor dormant battery life. The battery drops by about 10 percent for every 1 hr, when the phone is not in use(ironic, cos when the device is actively used, MIUI seems to have the best battery life). I checked the built in battery usage chart, and the thread that keeps the device awake is Android System itself. Is this a known issue? and are there any solutions available?

Had same problem!
Had exactly same problem a couple of months back and posted question here but no response.
I was able to initiate deep sleep but had to do various things such as reboot time after time until successful, open up a variety of apps, use a task killer, etc., to try and resolve problem.
I was using CM 6.0 initially and even updated to the latest update of that build by wiping everything but all to no avail. I was beginning to think that it was a hardware problem when I flashed an entirely different rom - MIUI 1.2.25 and hey presto problem resolved.
I suggest that you may have to do likewise and try another rom entirely. BTW the battery life of 1.2.25 is very good indeed. I also recommend using CPU Spy found in the market and/or CPU Stats found in the Themes/Apps section of this forum to monitor deep sleep status.
Hope this helps

[Q] Extreme battery drain

Hi guys,
i recently bought a LGOS and soon began to tinker and try out custom roms. and right now im running into a problem i couldnt solve by searching through this or other forums. i tried out several different roms with different kernels (modaco, swiftextreme, stock (froyo and gb), cm7 newest nightly) and with every rom my battery drainage is way higher than it should be.
with battery monitor im reading values between 100mA and 900mA when the phone is in standby mode and not being used! the temparature is also quite high ... round 38°C
on some forum i came across the problem with FD dormancy, and because my provider ( eplus) doesnt support fd dormancy i tried using a workaround by shutting down the phone application everytime the mobile data connection is being disabled... but it didnt help.
so i tried wether or not my problem is related to an app or service. i shutted down every process possible and the problem still persisted. i also tried disabling go launcher and using the stock one, but it didnt work.... im using no widget at all on my desktop right now
i tried wiping my battery stats through clockworkmod recovery. and it didnt help.
right now im beginning to believe that this problem is hardware related. im so frustrated with this :<. the phone itself is awesome, but this problem makes it quite hard to love it :<
thanks for your help

update: for the most part the problem was related to bad battery calibration. now the battery consumption is "only" ~50 mA in standby mode... the phone i had before, a "htc hd2 with newest hyperdroid rom" only consumed 3-5 mA when sleeping. when playing 3d games like gameloft's "order and chaos online" battery consumption on my LGOS averaged round 20% in 30 minutes of playing ... is this value normal?
the situation is still not very satisfying :<

Update: i noticed that the battery voltage stats are totally weird. The battery monitor values seem to jump from low to high values while discharging. I also stumbled across some thread regarding cm7 from April. The battery driver from LG seems to be faulty. Is there any fix ffor this... I'm using modaco right now
Sent from my LG-P990 using XDA App

another update in this conversation with myself :
i tried using cm7 ... and it actually made my problem even worse. the phone discharged in less than 5 hours while in standby. now im back to modaco... discharge rate while in standby is ~40mA.
is there anybody else on here who can help me ? :<
i guess i will need to sell this phone :<

sounds like a hardware problem, maybe you should send it in for a repair.
anyways when using the phone it normal that the battery is empty after 5 hours or so... but that should not happen in standby. does it happen with a clen install an withoit anything installed?
Sent from my Optimus 2X using XDA App

thanks for your reply ... my father just also bought an optimus 2x... so i will do some comparisons to check what exactly the problem is and wether or not it is software related. my last step before sending it in will be to revert back to stock froyo and install no app at all and check if the problem still exists ...
damn this phone is costing me many hours of stress and work ^^

[Q] Phone runs hot, High Drain - All usual fixes tested.

Device: Samsung Galaxy S GT i9000
Symptoms:
When Charging Device is hot to the Touch in the upper half of the screen and on the rear between the camera and the heat vent.
Battery drains at around 15-25% per hour when IDLE. 15% when in deep sleep in airplane mode with ALL APPS KILLED. 25% when I leave ALL network connections open and allow sync.
Phone was new less than 2 months ago. Still under warranty and I will send it back if no ideas come from this but wanted to see if anyone had a solution as I have noticed HUNDREDS of similar posts all vaguely scattered through different threads on different sites around the web and this seems like the definitive place to come to see if anyone can put their finger on it.
When did this occur?:
A short while after (days) of flashing CM9 nightly from the beginning of June (05/06 I think but can't recall exactly).
Tests performed:
Purchased new battery and fully charged - no change.
Flashed stock GB ROMs where the issue had not occured - no change.
Cleared battery stats several times - no change.
Tried different modems/radios including Nexus S radios- no result
Current ROM: CM 7.2
Kernel: Glitch 13.1
Other ROMs/Kernels where the same results were achieved...
CM9 (latest nightlies)
Stock JVU, JVS, JW4 and JW5
Semaphore Kernel, Devils Kernel
I use Voodoo Sound/Colour kernels apart from the testing I did with stock ROMs
Will leave it on over night after clearing stats so you can see for yourselves.
Any questions ask away.

I should add:
Used OS Monitor and one of the more detailed CPU monitors to look at what was going on.
Did not appear at any time to be using what I would consider high CPU utilisation, typically trending between 0 and 30ish. No background apps running, all radios turned off.
The only anomaly that stuck out at me is that system_server was using ~105% of RAM which I would have thought was rather difficult. Made me wonder if there was something loading/unloading itself from RAM.
As I am a heavy music user I have tested the Mediaserver issue where corrupt files are continually scanned by mediaserver process. Removed all media files from both my external and internal storage then formatted both while on a stock ROM (JVU and JW4). There was no change.
EDIT: I should add - The thing that makes this so strange to me is that the battery decreases at a rapid rate when Battery stats regarding usage DO NOT CHANGE. The percentages for the apps that WERE using the battery - i.e. winamp/mediaserver/android system do not change.
The reason I have posted this is that i have seen literally HUNDREDS of people posting this very same issue but never in the same place and never getting an answer.
Also - Thankyou to the kind mod/admin who approved my account so I can edit stuff. It was getting a bit annoying for the first week there.

Re
Hi,
To be honest I never heard/read of the problem you are describing. Most users report high battery drain on a certain ROM/kernel/modem but you say you have tried quite a lot.
If the phone is new, the only thing that comes to mind is that the USB charging socket is faulty. It may not charge properly or even have some bad connectors that are damaging the battery.
In any case, Samsung support is the way to go here.
Hope this helps

OMG, im having the same exact problem... the phone is super hot on the back where the sim card is inserted. I did everything as you, still no change, my battery lasts like 7 hours on deep sleep. Guess our phone is broken. super crap.

Anyone knows how to fix this? Is there anyway that my phone has some files from previous custom roms even though used odin to flash samsung original ones?

Had the same problem when my device was only 6 months old, the battery was becoming faulty, got a new battery and problem solved.

I bought a new battery and i still have the same problem... which battery did u get?

An official samsung battery from Amazon, re flash you device with another rom and wipe battery stats.

Did all that, the problem still continues... mega battery drain and the phone is at 44C degrees... is there any tool i can use to diagnose the problem?

Hi snaleman,
You could try BetterBatteryStats, to help diagnose your issue further, there is a paid version on the market (Google Play Store). There is also a thread on this forum, from the dev....hint
I tried winamp for android, ages ago, but had similar issues. (This player might well be your issue.) So I now use "PowerAmp". Neutron MP is cool too.
Also, do you use lippol94's kernel cleaning script. I use this every kernel/ROM change.
Search here for this:
ultimate_kernel_cleaning_script
Hope this info helps your baby.

Hey
U can try to flash a stock rom from sammmobile.com..
Use it for a few days and check...may help u..
Cheers

Backup your apps with titanium backup or something else.
Make a backup from CWM recovery
Wipe data/cache/dalvik
Restore user apps and not system app
If your problem is not fixed you can restore your CWM backup

Nothing you guys posted worked... battery lasts 11 hours on sleep...

Another problem that im facing is that when im on a phone call, theres is alot of breaks in the other persons voice and sometimes the voice call goes out and i lose all my network signal.

If you are using the Voodoo sound app that may be the cause. I've noticed on my phone that deep sleep no longer works when the voodoo app is installed, most likely the app is holding a partial wake lock and not releasing it.
See if it happens with the app uninstalled or frozen.

You've just made me think of something else that it may be.
Do you have 4 or 5 bars of signal strength?
I've found when in certain areas (very close to "deadspots" in network reception), that if I use another frequency, [eg. 900 & 2100 (for my network), yours may be different] I can get a better signal, also much better battery life, as the phone is not struggling to reach the network.
If you use your dialer to enter this code
*#*#197328640#*#*
Then
[1] DEBUG SCREEN
THEN
[8] PHONE CONTROL
then
[7] NETWORK CONTROL
then
[2] BAND SELECTION
you will then have a selection of frequencies available. The asterisk * will tell you what one(s) is/are active.
"Google" your network service providers frequency bands. I found mine were on a "Wiki" page.

[Q] Battery health

Hi, I would like to know the best way to measure my battery health. For about a month my battery starts to drain fast. I know my phone is already old and battery don't handle the same charge, but I have recharged the phone all night long and in ten minutes using wifi to just update some apps the battery just gone.
It is just ridiculous as I don't use any different configuration.
To be more specific, my phone configurations are:
- Cyanogenmod 7.2 by vo-1 (31/06/2012) deodexed by me;
- Firekernel Unnoficial OC (22/07/2012), CPU governor: smartassv2, max 787, min 245;
- Adrenaline Engine 4.2b;
One more thing. I was facing the same problem with blackhawk kernel.
I just think a battery can't die a sudden.
Could anyone help me with this?

There are a few things that can be causing this, but the first thing that you can try is to wipe your battery stats using "BatteryCalibration" app. After flashing a few things, it's best to do this. I had the same thing happen after flashing my third ROM or so.
After that, it basically comes down to the apps and widgets that you have running. Shut them off with a task manager so they don't end up draining your battery, but it might not be that either....
The only other thing that I can think of is that I heard in another thread (I really wish that I could find it again ) that the ace has a motherboard fault that causes it to drain faster than usual.
Other than that, all I can say is that the Ace generally has poor battery life, and it really does suck, but I don't really know how much more you can do. You could try flashing a stock-light ROM and see if it does the same thing (wipe battery stats too). But I would say is that you should try wiping the stats and see if anything changes.... Other than that.... I`m out. Hopefully it helps, and if it doesn`t, you might need to take it in (Service Center or wherever you bought the phone).
Maybe try searching in other threads (as it is a common problem) but besides that, goodluck :fingers-crossed:

I forgot to mention but I already did the calibration, using the app and manually to see if I could get different results.
I even tried to force a better charge, charging the phone off, waiting till 100%, unplugging and recharging, till the phone gets 100% again.
Ace's battery isn't good, but a month ago my phone was holding 12-14 hours without charge, using wifi a lot, that's why I think something is wrong.
Well, I'm flashing the original stock rom to see if get some change.
Thanks about the motherboard information, this is new for me :good:
Gonna see tomorrow if the battery holds better with the original stock ROM.
Thanks again!

Wiping the battery stats is a myth. All it does it clear the battery usage screen!
Android has a built in tool which can try to check the health of your battery.
Open the dialer
type *#*#4636#*#*
then go to battery information
Look at battery health.

Feedback
Just to give a feedback, my battery was really damaged. I bought a new one, stock because I didn't find other, and the phone now easily last a day, even using wifi a lot.
But that's not the only reason why I posting here again, I want to share how my old battery is. Comparing with new one, I realized that the old battery had stuffed something about 5 mm
If you pay attention, you'll see the small deformation.
Don't know yet what could have cause this, but I think it was heat and bad recharges...
Thanks for the help :good:

I'd recommend you to use SetCPU to prevent this on your new battery. Set up a profile with sound notification when it hits around 40degree, and underclock it at the same time.

I faced a similar problem. Battery was hardly six months old when it died but it was my fault. I was running a wi-fi tether and continuously charging it for about two days. :silly:
Got a new one under warranty. Been a year with the new battery and just recently facing problems with it. 3G just sucks the life out of it.

OK I just got 3g on my phone (yay for promotional 6gb plans!). But yeah, the 3g definitely kills my battery. I used to be able to go two or three days with very little use. Now I can only go one day even with standby with my 3g enabled. As long as I can put my phone on to charge before it dies, its all good to me
Finally with my 3g going, I understand everyone else's pain with the battery life haha
