Have you tried turning off 3G?

I also had this issue battery drain was huge. It started appearing suddenly one day. Its a very slow process to figure out the culprit. I did a step by step analysis.

1. Found out that battery drain was happening only when 3G was on. Verified this by switching off data network (long press power button to deactivate).

2. Also verified abnormal data usage in my carrier page when I was not using my phone [like - 3G was on and I was watching a movie at a theater].

3. I also saw abnormal battery drain soon after I started Google Maps after a fresh reboot.

4. So I identified the culprit - Google Maps - but was not sure how to solve battery drain [Google Maps restarts, if you kill it].

5. I installed a variety of apps to identify the battery hog. Finally I went for Task Identifier.

6. Task Identifier finally showed me what programs started while my screen was off, etc. And I started noting them. Finally I figured out that Google Maps::BackgroundFriendService was running frequently.

7. A quick search on Google helped me understand that this is about Google Latitude. It searches for your friend's location every now and then - leading to battery drain!!! :mad:

8. I opened up Latitude and signed out from it [I guess the sign out option is in Menu -> Privacy].

9. Do not re-open Google Latitude after this - you will get signed in again leading to battery drain.

10. After 2-3 months of search and prodding, I finally figured out the cause of battery drain and fixed it - now I get 2 - 3 days of charge in my battery under normal usage!! :D

I'm happy now!!
[Galaxy S I9000 General] morgun007:
Hi again the same question, please which ROM would you advice me?

Or at least please answer me this: I wan to update to I9000XFJS2

I downloaded the files from link in first post

http://xdaforums.com/showthread.php?t=936252

I want update firmware with repartitioning.

In the .rar are this files

cache.rfs

factoryfs.rfs

modem.bin

param.lfs

zImage

Which files should I choose during updating FW? From this is only modem clear to me...(on 2nd page on pictures with odin there are wrong names of files so also useless)

PIT - 803

PDA - ??

Phone - ??

CSC - ??

I want to use odin 1,7 and PIT 803

Thanks
[Galaxy S I9000 General] MissNLink:
don't repart js2

i believe that you need the js3 firmware which is glowing in orange colour on the samfirmware site, as this f/w allows you to re-partition, inside you'll find the pda(the big file), phone(which is modem) and csc(which is csc, strangely enough). it is the first f/w with the 803pit for 2.2.1 listed.

then you can flash the js2 update safely, WITH NO-PIT or repartition. that is, put the js2 tar in the pda slot and flash to your hearts content.

rock

is this in the correct thread???
[Galaxy S I9000 General] bokbacken:
This is the wrong thread for this.

Go to Doc and Stefunels romkitchen or Darky's Rom and try them out and keep the ROM questions in their thread and battery drain issues go in this thread.
[Galaxy S I9000 General] morgun007:
I believe as there is connection between different ROMs and different drains, that question "which ROM would you advice" me belongs to battery drain topic.

Anyway thank you, especially to MissNLink
[Galaxy S I9000 General] MissNLink:
cheers for the thanks..

as far as the rom connection goes, there has been a lot of thought that the choice of modem(or phone) part of the rom can play it's part in draining the battery. i have read many theories on "i used this rom and my phone heats up bad" this says to me that the cpu is working hard which in turn means the battery is working harder.

the search for the right modem part of firmware goes on & on, but many have been swapped around and tested, but i am yet to hear a definitive answer.

mainly cause of all the different combinations of apps, roms, product codes, csc's & firmwares in general use.

but i am sure of this :- work a cpu hard - it heats up, power that cpu with a mobile battery - the battery gets used up faster.

will the right combination please stand up...
[Galaxy S I9000 General] bokbacken:
There is no solid proof that a specific ROM would be better than another, it's much more about the apps that are or could be preinstalled in the different ROM's.

And as the ROM's change all the time then if I were to say that Doc's is better then Darkky's today then tomorrow it would be the other way around.

If you find something specific that is ROM based, not due to some app they choose to include, then it could be something for this thread but otherwise we keep out of it.
[Galaxy S I9000 General] bokbacken:
About Modem, if you are to reccomend a specific version you have to take in account what region, operator and datamode before suggesting one or the other.

Personally I am using UGJL2 even though I'm in Sweden, I'm on 3 so I have all communication on 3G, GSM/GPRS is not an option for me it's not available but I still get 2 days of usage on my phone.
[Galaxy S I9000 General] MissNLink:
well let's hear the list of apps so we can learn. you brought this thread to life, nurture it, so it can grow.
[Galaxy S I9000 General] basti107:
the draining stays the same even if no simcard is in the phone...

will try taskidentifier but i do not think its latitude or maps because i do not use data-connection.
[Galaxy S I9000 General] man:
First of all, sorry for my english, is a lot of time i don't write in this language.

I was having a lot of battery drain, when the phone was idle. I testes different ROMs, Kernels and different lagfix and tweaks configs, but the problem always existed. I was having about 4-5% in one hour, when wifi or 3G on. So i started to use juicedeffender or tasker to reduce that battery drain. Using this programs, i achieved 1% per hour when phone idle.

But on last tuesday i tried to install a new ROM from my spanish forum, and now i'm getting extraordinary results.

First of all, formatted internal sd and factory reset. After that, i have installed JPU, afterwards JS3 and finally the Custom ROM.

Now i'm having 2 days of battery life. I'm getting about 1% drain per hour, but with wifi or 3G ALWAYS ON. Also brightness is automatic, windows animations, live wallpappers, etc. Phone is set up without any config to save battery. Use is about 2 hours screen on browsing Internet, etc, more than 30 minutes calls, 10 minutes GPS.

There are some people that is saying is not getting great battery life with this ROM, but i'm getting my best results since i have this phone (3 months ago)

I'm starting to think that our battery problems are due to the way in which we are installing our ROMs. My last installation was with batttery always fully charged, and in the way that i have explained before. Hope can help somebody.

I cannot post the link to this ROM, but i can tell you that is published in the htcmania forum (Samsung galaxy s subforum) and its name is ClouXDroid v4 Black Monster.

Well, well! you wanna be spoon-feed all your life? This is not a one-man show, I have put in a lot of hours and investigations here, a good thread will get a life of it's own and with contributors this will happen (as long as there is a demand).

The maker's of the ROM's and Kernels have eliminated a lot of the bugs that we (me and the contributors) have found (and spread information about) so today you get a much better ROM from the development thread with less problems.

Today they also take people serious when they get report on battery drain, 1½ month ago that was not the case.

I'm not online on my thread 24/7 now, I do have a life;), but I do follow the development searching on NEW findings, but they are rare nowdays, the super drainers are more or less gone, so more and more people are happy with their installations.

So I ask of you, please nurture this thread by becoming a contributor, look how Darkyy and Doc's threads have helpers, one unpaid person can't give to everybody, xda is about helping one another, I've got a lot of help from different threads, and then it's only fair that I give help to others.

Update:

Completely wiped phone, formatted SD, turned off all lagfix/tweaks in recovery, wiped caches, installed Docs Rom with no extras apps, Harcores kernel, basic TouchWiz interface, didn't install apps but juiceplotter.

> Still used around 5-7% an hour on idle (data on).

Figured it must be a battery problem, so yesterday did a full discharge, full charge with power off, reset battery stats, turn on and full discharge again, full charge again.

> Problem still exists, around 5-7% an hour on idle.

Turned "Use wireless networks" for location off, Latitude signed out.

> No difference.

Running the 'Task Identifier' app now, but I'm quickly running out of ideas now. If I didn't use Tasker to turn the data off every few minutes the phone wouldn't make it through the day on suspend!

And I'm going a bit blind to it all! I'm looking these graphs and not knowing what is normal or not any more! 5% or more an hour is bad on JS3, isn't it? :confused:

Maybe it's a faulty battery? Anybody found a new battery has fixed their problem?

Slowly going mad, but not giving up! ;)
[Galaxy S I9000 General] basti107:
i have exactly the same problem.

bought a new battery but still the same prob. tried nearlly everything...
[Galaxy S I9000 General] king.com:
Hi LPY :)

I also try to measure battery drain using this method. After wiring, the phone doesn't turn on. I works fine with direct battery connection (like noral use), but when I bridge "+" trought my tester (like your picture), the phone doesn't turn on. When I press Power on I can see consumption about 50/55 ma but doesn't start.

Any suggestion?

EDIT: Faulty cable, sorry :D

But now battery meter got crazy. Battery abiut 50%, when bridged got about 7%, pull out battery and place it again. Batery is about 70%, but 5 minutes after phone shuts off. And all cables are right now.

Again... any suggestio? ;)
[Galaxy S I9000 General] thecresta:
I'll give that a miss then - cheers for saving me a bit of cash ;)

I haven't read all of your posts, but if you turn data off altogether, or turn on flight mode, does the Juice Plotter graph flatline?

In my Juice Plotter, when data is enabled something is making the graph 'jitter' every few seconds, even when the screen is off. But I can't figure out what's causing it!

I'm confident we'll get to the bottom of it though :D

Edit: Could you let me know your current setup please - ROM, Kernel, Modem? Maybe theres a link somewhere...
[Galaxy S I9000 General] tomeks:
for me it is 'suspend' process which is causing the battery drain

it is happening only when wifi is on and the screen is off

it is using up to 20% of the cpu, so the solution is to turn off wifi

in finding such a process try to use 'systempanel' app, in paid version it could monitor proceses and cpu usage
[Galaxy S I9000 General] henriquesb:
Use something else, JuicePlotter was killing my battery on Froyo! I'm now using BatteryMinder for estimates, battery lasts a lot longer.

Didn't had problems with JuicePlotter on Eclair though.
[Galaxy S I9000 General] lpy:
The only thing i could suggest is keep the wires as short as possible. There is some current loss through the wires which is what causes the battery meter to go a little crazy.
[Galaxy S I9000 General] thecresta:
Will do, removing it now, thanks :)

I found something interesting that may help someone:

When I go Settings > Wireless & Network > Mobile Networks and untick 'Use packet data' my battery usage drops to well under 1% an hour.

If I leave that setting enabled, but use SwitchPro / APNdroid or another app to turn off the data, the G/3G/H icon disappears, but my battery drain is still through the roof (5%+)!

So disabling the Access Point Name, but keeping the Data service active is still contributing to high battery drain (whatever the data service be, I haven't looked into that yet).

So with that in mind, does anybody know of a widget or app that actually turns the 'Use packet data' option off, instead of just deleting / renaming the APN?

Many thanks in advance for any help!
[Galaxy S I9000 General] KennyLegend:
So is what ur saying the same as turning off data from the extended power menu ?

EDIT: Im using "tasker" from the market to turn off data completely when my screen times out. Its a paid app but well worth it.

My story:

Was experiencing battery life of 12-16 hours on stock 2.2.1. Now I am on js3 with SpeedMod kernel, AND I have stopped using Yahoo mail, and only manual FB/Twitter sync. Only Gmail, calendar and contacts are automatically synced/pushed. Airplane mode during the night (autosetup with Locale). Voila, it now lasts 36-48 hours...
[Galaxy S I9000 General] thecresta:
Hi,

When I untick "use packet data" in Mobile network settings my battery drain completely stops.

Haven't tried Extended Power Menu - updating it now.

I have yet to find a widget or app (including tasker) that can untick this box. They do something different that doesn't completely disable the data connection, and whatever is left running (eg: a service or driver) is causing my battery drain.

I'm trying to work out what that might be :confused:

Update: The Extended Power Menu option works! It ticks/unticks the box! That's something to work with... :)
[Galaxy S I9000 General] king.com:
I'm fighting against this 1% each hour, what is the same 6%-8% overnight.

Did you think that 1% per hour is ok? I did some testing and some nights I got 0%1% in 6-7 hours. With stock JPO always was that 0%-1%. Also Samsung says about 30 stadby days. I don't want to get these 30 days, but i don't want to drain my phone when it is idle :(

Note that battery always had a good calibration.
[Galaxy S I9000 General] basti107:
what happens if you flash back to jpo? do you still get the 0%-1% idle-drain?

i can flash which rom/firmware i want, alwas get 3%/hour idle-drain.

i really think there are differnt phone-hardwares out.
[Galaxy S I9000 General] king.com:
Yes I have a CWM backup with the JPO stock firmware with a lot of apps and widgets, and yes, I have 0%-1% overnight :confused:
[Galaxy S I9000 General] thecresta:
Chainfire gives a useful explanation of the above here.

Trying Voodoo kernel at the moment to see if it makes any difference, first observation - Wifi not working :rolleyes:

Update: Better with Voodoo, but still 3%-4% an hour idle. Going to try Darkys Rom later, and see how it goes tomorrow.
[Galaxy S I9000 General] robochrist:
I'm not entirely happy with my battery life on my Galaxy, but then again this is my first smartphone so I'm not sure if it's normal.

When I'm browsing the internet for half an hour and and use maps/streetview/earth for another half hour, I'm down 25 to 30%. This is with the screen 3 or 4 ticks brighter than the lowest setting and over a 3 bar wifi conection.

That's at least 25% per hour, that can't be right, can it?

I'm on Darky 9.2 with speedmod and no lagfix by the way.
[Galaxy S I9000 General] rizzy123:
That isn't normal. If your trying a new rom, try using the wipe version which has worked for some people or use darky's resurrection rom which is supposed to fix all issues and has fixed the battery drain for some people.
[Galaxy S I9000 General] brack11:
25% per hour working in wifi? I consider it to be very saving. I have up to 40% for hour working Google earth or even with tapatalk, that is the problem. My idle drainwalso kinda strange I have 0 used from 2100 till 0300 and then 1% for 40 minutes. There is nothing scheduled for this time, the phone is in airpain mode, nothing special is running.

Sweet time when I had stock jpo on my phone with 0-1% per night. Maybe I should try to go back.

the one man show club

Not a one man show? i believe you maybe fooling yourself, just a little, as this is not how you can portray yourself through some of your replies. When someone asked for help and i try to make a contributional reply and also nicely (in defense of your thread's topic) try to point out that their request maybe in the wrong thread, we cop your narcissistic rash.

also quote : 'Rom's & Kernels have eliminated a lot of bugs that we (me and the contributors) have found' do you realise you sound like your part of some exclusive club, i don't know, maybe that's how you see yourself. But i and plenty of others look to xda forums for helpful guidance and information garnered from experienced like minded people. Not lectures from wannabe school masters playing judge and executioner just as your avatar so appropriately conveys. Darky's & Doc's threads have helpers cause they feel supported. If you want to be fair and give that help that you received from xda to others, try not stomping on them, we're more than just text on your screen.

They're just phones for christsakes and we just want to control them better, not each other. Maybe lighten up a bit, you can sound like you're not enjoying this other life you state you 'have'...:o:cool:

Ok, how can I let my custom bootanimation to run PowerOn sound??

And if my phone was silent before shutting down?? When I boot it up it does not play the sound, right? Or does it paly it but does not come out from the speacker because is in silent mode??

I often boot up in silent mode......and it would be always a bad thing to go and turn on sound, play a sound and then put it back in silent.

Removed bootanimation on doc's, cleared dalvik, the first couple of hours saw reduction of battery usage in mA but after a little while usage came back, looks like dalvik had something drain related. Now I'm planning to recharge and reflash but with only needed apps, so, I will not restore most of crap. Anyway, before I proceed with this plan, I will wait for doc's new base, wouldn't be wise for me to flash a day before body will ask for flashing new stuff.

During all the day, while sleep, my phone was doing a 1% each 4-5Hours. Well

About at 21:00 I rebooted with no particular reason, just for testing. From that momento was draining about 3%-4% each hour.

I'm using BatteryMinder for estimates instead of JuicePlotter as the latter was draining my battery in Froyo. One cool thing about BatteryMinder is the momentary estimates, as it provides you the current consumption rate.

Disabling the tweaks in Speedmod made it last longer in 2G (and probably 3G as well) but I still couldn't find a solution for Wifi.

Using Darky's 8.1 on JPY with JPX modem and the JPA wifi driver. Also tried the BUJP5 modem without success.

If you still have battery problems, flashing some other modem (like JP5) can help (it did with me ^^)

I installed JP5 a few days ago and battery life has definitely improved, although only a little.

So when I finally get the battery back to its normal cycle I'll continue to use the JP5 modem and it should last even longer than before - bonus! :D
