Final Update :)

Hi All,

Quick update, my battery life had improved dramatically over the last week.

I took it off charge at 07:30 yesterday, and now (11:30) it is at 34%.

This is with moderate usage, lots of app use, downloading and updating, kernel flashing, lagfix conversion, with System Panel monitoring and JuicePlotter plotting. Wifi, data and sync on all the time (2G, switching to 3G when browsing, 30sec timeout for WiFi), with a fair amount of PowerAmp set to max bass and treble (Daft Punk Tron soundtrack - awesome!), auto brightness and a nice colourful wallpaper to top it off :D

Not bad considering a couple of weeks ago it didn't last a full day WITH NO USE. Very happy I can use my smartphone like a smartphone again!

I uninstalled SuperPower and Tasker as they appeared to be draining battery instead of improving it. I'll re-install Tasker eventually and try again, as it's my favourite app ;)

Here's what I did if anyone's interested

Okay so. had my GS for about 3 months and right from the get go Ive had horrid battery life.. Its now to the point where I will charge my phone overnight to 100 percent. get it off the charger at 8am. by 8.30 its already at 91. I barely touch the phone except for the odd sms throughout the day aswell as about 2 hours music play. by 2/3pm. battery is,dead.

gps off, wifi off, voodoo, launcher pro, bw, lowest brightness syc off.

rooted

faulty battery?
[Galaxy S I9000 General] KennyLegend:
i had this issue with my sisters SGS. i flashed it for her with a doc Rom and voodoo kernel and she barely got 7-8 hrs with little or no use.

i flashed it again with the same Rom and hardcores kernel this time and she's getting 3 days with light use. im putting it down to a bad flash rather than just the kernel.

kinda similar to what i did with mine except i cycled mine after flashing

Thanks a lot, this really helped me!
[Galaxy S I9000 General] guika:
I suggest to try hardcore kernel. I had the same problem with voodoo.

I guess i read this story many times at xda so sgs are different and tgere is something in voodoo which could affect this. I read yhis story backward also. So give try flash speedmod wipe dalvik cache make 3cycles and write back your results. If not battery could be dead.
[Galaxy S I9000 General] Jo5hw:
I'm still pretty new to the modding scene, which Kernl and mod do you suggest? and where can I find them?

Cheers :)
[Galaxy S I9000 General] KennyLegend:
id suggest using a doc Rom and hardcores latest speedmod kernel.

enter Docs kitchen through his thread in the android development section and cook up a Rom.

pick a modem suitable to your network/location. you can select the kernel and your preferred theme there too. then flash.

, id suggest reading docs thread entirely and links attached too if this new to you.

Sent from my SGS
[Galaxy S I9000 General] guika:
What is really important if you install doc rom to your phone is:

Check your 3 buttons combo is working. Recovery node download mode

Make a rom like above post.

If you are in europe and you are not in vodafone i suggest the asian version of modem called zsjpe. ( in hungary with telenor i use this)

Cook a rom with your like programs etc.

Go to recovery mode.

Disable any lagfix

Wipe data wipe cache partitions

Install zip from sd card pick up your previous downloaded rom.

Install

After that diwnload speedmod k13c cwm version kernel.

Go to recovery install zip from sd card pick up your cwm version kernel. Install

After than go to wipe out dalvik cache its different like i wrote before!!!!

In your new rom install sgs tools it in the xda. And replace the gallery. Because the origy gallery is a drainer.

Thats all.

Method two.

In your current rom.

Download speedmod. Odin version kernel.

Disable lagfix.

Go to download mode flash your kernel via odin.

Wipe out dalvik cache.

This method could give you bootloop. Because i dont know your rom and other infos. So method first is a safier way.

Its important that your 3 buttons mode is working. If not andnyou have a bootloop you can go to download mode oonly with a jig.

I hope you will get success.
[Galaxy S I9000 General] Jo5hw:
Thanks heaps guys! Ill do this saturday and get back to you with results.

Suggestions for posting before and,after battery performance?

Out of curiosity, What kind of Quadrant scores are avg for said kernel and mod? + real life performance compared to voodoo.
[Galaxy S I9000 General] PIRATA!:
Please...is there a nice quite fine procedure ofr ricalibration that is something like a must for all of us??

Thank you.
[Galaxy S I9000 General] KennyLegend:
i think quadrant scores average about 1600 with lagfix enabled but in real life usage it doesn't matter.

as fast if not faster than voodoo kernel and a lot more efficient .

Yes on these very pages . Its often best to start on page one ..

Or basics for lazy buggers

One dont expect a bad rom to improve your battery if it has lots of posts about battery drain look at another rom .

Two drain battery and wipe battery stats .

Three Charge battery > drain battery then charge to 100% >> bump charge battery a couple of times .

Four Use phone wait until battery low then give it a long charge just leave it plugged in .

Five sort your apps and dont use thos e that drain the battery in particular constant searching for wifi when not needed .

SGS Rom Kitchin two days 24% battery used .

[Galaxy S I9000 General] guika:
Quadrant sucks. I could give to you from 1000-2200 in quadrant with speedmod kernel.

It depends on your life,feeling, usage.

If you feel that your bttery is fine and yoursgs fast and responsive than

Forget quadrant.
[Galaxy S I9000 General] KennyLegend:
+1. quadrant score has never had a noticeable effect on my SGS regardless what score i got or regardless of what kernel i tried.

neither has it had an effect on battery life.

I had horrible battery life since using Doc's Kitchen. I drained my battery until the phone wouldn't turn on anymore. Plugged the phone in and let it charge with the phone off. Unplugged phone, booted straight to recovery with 3 button recovery, cleared battery stats, used phone like regularly but everynight I charge my phone with phone off regardless of battery level and everyday my battery life keeps improving. I used to not make it through a day now I still have battery left at the end of the day.
[Galaxy S I9000 General] tzyn:
I got 1-2 days and i use the phone very often (whatsapp, email, browser, hsdpa always on, auto brightness, ...). That's with SpeedMod Kernel (now Insane from xan because of UV/OC) and JPY 2.2.1. Great performance and in my opinion a good battery life.
[Galaxy S I9000 General] h1shahar:
Hi,

I had a process 0 with 100% network usage of 100% according to spare parts.

I found out that "gesture search" was causing the problem. Not sure is was actually using the network connection but it might have been working in the background.

FYI

[Galaxy S I9000 General] henriquesb:
Managed to improve my battery: Speedmod K13a with auto brightness and cold colors without tweaks, 2G, JuiceDefender 5min week + 15min weekends, plus ScreenFilter at 70%.

Seems decent even during the day, and I usually end a work day with 70% left (was fully charged in the morning).

Keeping the GPS software in night mode also helps.
[Galaxy S I9000 General] xxbeanxx:
Just wanted to comment on an issue my wife was having with her SGS. One day she noticed her battery was draining completely in about 2 hours. I installed an app called OS Monitor and noticed that social hub was using quite a lot of cpu. I cleared data and cache on this app and it fixed the battery problem. I am sure it was this because she was having the issue for 3 days and it suddenly stopped when I did this.

She now uses stock email app because social hub sucks.
[Galaxy S I9000 General] NetCopAD:
OK, WiFi drain again for me. Last time I had that problem it was resolved by kernel modifications by hardcore. In fact with my current setup I had the best battery life ever - 40 hours with my normal usage ( I usually get 24 hours max)

However one day just like that (after a restart actually) the battery started to drain extremely fast (8-10%/hour). It wasn't hard to find it is the WiFi causing this.

Now I have currently set my WiFi to turn off with screen and this solves my battery troubles, but is'n exactly the way I want it to work.

So... anybody PLEASE any idea how to fix the damn WiFi?

I tried wiping caches, uninstalled software, tried JPY and DXJPA WiFi wirmwares. No good :(

Any ideas are welcome. I would like to avoid factory reset and reflashing and it also doesn't make much sense as my current setup was working fine.

I'm on Doc's 9.6.6 K13C
[Galaxy S I9000 General] guika:
I realised the same wifi issue with darky stock doc rom.

I tried all wifi wlvariants in the xda and its eating the battery. Something should be inside. That would be great if any devs could watch it.

Ibalso realised that if i copy download sonething with wifi. The cpu usage gets high. Dobt know why.

Maybe if anyone could make a try with an open and wpa2 same routerbdownloading test would be great.

I think wpa_supplicant has a bug inside. Encrypting is draining the battery by wifi.

Please guys if someone could confirm or cancel my idea. That would be great.

I also realised that cfq is also using 20-30 of the cpu with wifi.
[Galaxy S I9000 General] guika:
In battery drain issue i tried tu use autorun manager. In tge donated version you could switch off so many receivers for your whole app.

Like in my facebook app i disabled logging receivers.

So i otherhand you could switch off those process for every apps which are really not neccesary for using it.

I could not measure in usage time but i think you could make a try with this app.

Battery report (hope this give a better base for comparison):-

Phone Setup:

3G + Gmail + Sync + Data ON + Data Widgets update hourly (twitter, fb, weather, stock)

Active use (screen on + 3G surfing web + autobright) : 18-22% per hour

Standby : 1 to 1.5% per hour

BUT...with Data OFF

Standby: 0.15 - 0.2% per hour.
[Galaxy S I9000 General] h1shahar:
I can't get less than 3%/h when idle... with 3G + gmail

any ideas what can I do?

Battery stats wipe not found

Today I was plan to do a ''battery stats wipe'' but surprise, I was not able to find this option into the Recovery Mode...where can I find this option?
[Galaxy S I9000 General] guika:
You need a spec kernel. Like speedmod.

Or with a rooted phone you can delete it manually

Terminal emulator

su

cd data/system

rm batterystats.bin
[Galaxy S I9000 General] NetCopAD:
Well, as much as I wanted to avoid it I took the leap and flashed a clean Doc's 9.6.6 and all is back to normal now. Might have been some app I had installed or who knows what.

Too bad I didn't find the cause, but it's good to have normal battery drain with wifi on.
[Galaxy S I9000 General] mib1800:
Did you measure the drop over at least 8 hours idle? From full charge position, drop rate is usually higher but it evens out later.

What I do to look for problems (using Battery History app) - check to make sure you do not have apps that have high "Partial Wake" use. Also check the "Network Data" use to make sure no apps are transferring unusually high amount of data. (Ignore the "process 0")
[Galaxy S I9000 General] bigmo7:
Installed timeline pro to see if there was any reason I was having high battery drain and I found that the CPU usage if nearly 100% most of the time the phone is asleep. Can't really isolate the problem using spare parts either :o any help?
[Galaxy S I9000 General] h1shahar:
no strange apps under all topics in spareparts

still in most times i get 3%/h on idle plus i have monitored the cpu and it's around 30% when idle
[Galaxy S I9000 General] h1shahar:
see screenshot - something makes the cpu works around 10% when the phone is idle (between 1400 and 1800)

only restart made him got o the lower 3% area

no special app running

any ideas?

Hi. I'm sorry for bumping this post, but I dont know if this is just a usual drain or not since i'm new to Galaxy S. I'm currently running Darky's 9.2 rom with default options before installing & no extra Samsung apps.

I've charged the phone to 100%, then used an app that enables data only once in 1 hour just to sync otherwise, data/wifi is disabled. I dont run any background apps or anything similar. My phone battery is at 35% after ~24h. You have to know that I've barely used the phone. ~2minutes of games, 1 minute of checking mail, 2 minutes of calls.

I've been Motorola Milestone user before and I used phone alot (running Cronos or CyanogenMod roms) playing games, browsing web, using google reader and I got around 40 hours with that kind of usage.

Is this normal? Or should I calibarte the battery/change Kernel???

Thank you for your replies.
[Galaxy S I9000 General] mib1800:
On the same System Panel plot, on idle mine is at 3% or below. So something must be running constantly in the background for your case.

Can it be due to the theme you are using? I didnt use any theme - just the plain old Samsung one.
[Galaxy S I9000 General] bokbacken:
Hi,

From that screen you could choose Plot and then check application after application untill you find one that has been active during the same time.

A guess from my side would be email or media scanner.
[Galaxy S I9000 General] basti107:
i do not really understand how people get 4% loss in 8hrs or so...

it does not matter wich kernel/rom i use (even new leaked gingerbread version) i

have a constant drain 3%/h.

did anyone with the same issue tried testrom CM7?

my phone seems broken.
[Galaxy S I9000 General] ataky:
In my opinion this is normal. I have tried different kernels, roms, modems but i can do about a day normal usage with my phone. thats with watching avi movies, playing games etc.
[Galaxy S I9000 General] fashloka:
Still battery drain
[Galaxy S I9000 General] muffmaster:
I've fixed my battery drainage! :D

Had alot of problems before... Now I get 36-40 hours of usage after every charge even when using the phone alot! Used to have ~15-24 hours before.

How I've solved it:

- Installed the ROM Insanity (wipe version) 0.6.0 and kernel SOK 4.6.5 which seem to be a good combo for the battery, and everything is supersmooth and fast!

- Using the app Screen Filter to lower brightness to 62%.

- Using the app Tasker to shut down mobile data connection when screen goes off. (Works good for me, haven't tried current config with JuiceDefender)

- Completely discharge battery every time, before loading (preferebly with phone turned off) to 100% and then having the charger plugged for at least another hour.

- Using Voltage Control to UC, with the recommended values.

Have a nice day!
[Galaxy S I9000 General] Don MC:
Nice to hear that.

But completely discharging every time isn't the best thing to do, since these batteries are best kept at highest charge possible. They dislike being completely discharged but instead they like being fully charged.

Evenso, a complete discharge every now and then (once a month) is recommended for calibrating the battery gauge. Discharging every time is a no-no.
[Galaxy S I9000 General] henriquesb:
Me too. Darky 8.1 over JPY + SpeedMod K13a without tweaks + JuiceDefender, getting the same result, even more with light usage. Avoiding Wifi and 3G as I got EDGE coverage in most places, I can get two full days.
[Galaxy S I9000 General] guika:
Okay

In the weekend i made sone travel with gps and i realised something.

I used igo navigation. And 500mah charger.

With full bright i loose 1% in every 2 hour with min charge i got 1% in every 2 hours. So it means that if you use gps and app which needs cpu it will eat more or equal 500mah so with this you could depleed your phone in some hours.

Totally those post which say about how many days bla bla are not relevant.

The main thing is in the drivers and how many % do we loose when the phone is off or idle.

[Galaxy S I9000 General] Don MC:
I actually had the same with my old Nokia 5800XM. Navigating in the car depleted the battery even with the charger connected. Very slowly of course (about the same 1% per 2h). Not a big issue, but a reminder that GPS eats battery a LOT.
[Galaxy S I9000 General] brack11:
I installed power tutor app from the market and tried to do different things with the phone to find what takes over the battery and I see the compass process always active eating CPU, apparently this is dependent on autorotation feature enabled. I also found that if autorotation is enabled and I simply swipe the screen with my finger, spikes in CPU usage are three times higher than without autorotation.

I turned off Swype this morning before I unplugged the charger, and went back to the stock keyboard.

That was at 9:30 this morning. 8 hours later I'm at 85% battery. Usually I''m down to 60%-70% by now.
[Galaxy S I9000 General] utsmaster18:
Since changing to darkyy 9.3 with Speedmod K13c, my battery life has been really good in my opinion. Easily get more than 24 hours on moderate use (twitter, xda, email, games, one tv show, couple phone calls). Right now, the phone has been on, with data on, wifi off, background data off, and I've gone down to 2% in 6 hours which I consider good compared to what I had before.
[Galaxy S I9000 General] henriquesb:
I recently changed from SpeedMod K13c to K13a over Darkys 8.1, then to Voodoo 5.4.2 over stock JS5 with lagfix, and now I've removed the lagfix.

In all these setups I've been able to achieve nearly 2 days, depending on usage. The secret: JuiceDefender (with AutoSync in ping mode) + ScreenFilter. Regardless of the kernel I used. It's more about taming the applications data usage than it is about kernels nowadays, especially with mature kernels as Voodoo or SpeedMod.
[Galaxy S I9000 General] basti107:
Hmm, really think my idle-drain depends on the modem.

the best standbytime (data, wlan, background and sync off) i could get by now was 33hrs.

Now with darky's 9.5 including the JVE modem i get 48hrs!

Did anyone from germany fixed his/her batterylife with a new modem?

Whats the best for vodafone germany?

Hey all,

Posted in this thread a while ago with an 8 hour battery life problem whilst using VOodoo.

I've installed a custom ROM through Romkitchen, brightness is all the way down still.

No improvement. ideas?
[Galaxy S I9000 General] DrunkFuX666:
hmmm.... it seems like im the ONLY person who hasnt been able to solve his battery drain issue... man do i feel dumb... lol

Im currently using darkys 9.5... no idea what modem it is cuz im an idiot... and even when i try to use it the least i can... lowest screen brightness with screen filter as well and barely any use... like 12 hours tops... which is reallllly annoying... dont even have animations on or any other good stuff... use launcher pro tho...

any tips would be appreciated...!
[Galaxy S I9000 General] JJEgan:
Dont use that rom if it drains your battery .

jje
[Galaxy S I9000 General] henriquesb:
ScreenFilter + JuiceDefender or Tasker + JPG modem, check the "battery saver modem" thread as there might be other new modems coming. No need for custom ROMs to achieve more than 32 hours uptime. You're missing a good modem plus a program like JuiceDefender or Tasker to bring some discipline to the apps data usage. Keeping a data connection on all the time means spending more battery than you really need.
[Galaxy S I9000 General] enForce1:
I still don't know how some people manage to get that 1-2% / 8 hour period discharge with SGS. I've tried official and darky's roms but haven't managed to get below 1,5% / h battery discharge on standby. Also I read through this whole thread and tried out various things without good results.

I normally have wifi/mobile data/gps/bluetooth, syncronising and background data all off and I use JuicePlotter to check up on my battery life. Here's a graph from last night and today.

Before I went to sleep I put the phone in flight mode and the battery drained about 1%/h. I have no idea why the graph shows that I had screen on full brightness during 5:30-6:30 (I was asleep). Around 7:30 I took it off flight mode and the battery drain increased to 1,67%/h (the average during 8:00-11:00, mostly standby, just turned the screen on a few times to see the clock). From 11:30 to 14:30 I had mobile data and sync turned on and suprisingly the battery drain decreased to 1,33%/h average (with same usage as before). Logically it should have used more battery than without data+sync but I don't know...

Has anyone else had this kind of behavior?
[Galaxy S I9000 General] guika:
Should not the modem do it...

[Galaxy S I9000 General] nonyhaha:
i already posted in another thread, but thought i would do it also here. i haven't started a new one, so:

hello everyone.

because i don;t want to start another thread, i will post my problems here.

it starts like this:

i have been using xxjvk with stock modem and csc (kor) for some time, and realised the battery was discharging pretty fast. i installed the firmware the night it got out, and last evening i got these pictures:

i didnt play any game, just listened to some music, and only 30 minutes of talk.

so i decided to do a fresh install of everything. and i did the following:

- installed the stock rom, 3 files, with repartition, pit512.

- root with first method (xwjv1 cfroot no-cwm) because otherwise csc changing was not working

- after root, i pushed cnx csc and changet it to that (vodafone ro)

- applied cf-root 2.7 with cwm.

- changed modem to zsjpg!!

- aosp lockscreen by replacing 2 files in /system/framework/

- tvoff and battery mod by cwm update

- installed gingerbread stock lockscreen, keyboard, some games.

- charged it to 100% (checked in battery status that it was 100%)

- went to sleep.

5 hours later:

did i do anything stupid?? why is this happening to me? :)

i am going to stress it to empty the battery, and maby post som more pics.

i must say that any positioning method is disabled, as you can see no google battery drain, it seems that before the update the modem was the biggest problem , followed by the maps app. now, neither of them are present in battery drain status.

oh, and after the whole procedure, i did a reset on battery stats in cwm menu.

as you can see, during the night the data, wifi, bt, gps was off, and i was using 3g/2g network. vodafone romania.
[Galaxy S I9000 General] seby79:
What application are u using to monitor this?
[Galaxy S I9000 General] nonyhaha:
to monitor? android's built in battery meter. and to take pictures, ddms from android sdk.
[Galaxy S I9000 General] ipospa:
Battery Calibrator App

I am not sure if anybody mentioned here in posts App called "Battery Calibrator".

It should work this way:

Best if used right before your phone is about to shutdown, this application simply backs up and then removes batterystats.bin system file and gracefully shuts down your Android phone.

While your phone is completely OFF, charge it overnight and make sure it is a good FULL charge.

Then simply turn you phone in the morning - fresh batterystats.bin file will be regenerated by the system.

I am just testing it.
