You wouldn't see any difference on push, then they both work as supposed to, so it might very well be that 4% / hour is normal for you when on push, this might improve with another modem though, please try some to see if there is any improvement (there is a link in post #3 I think).

The bug with Samsung Email client is when you set it to sync every x minutes, then it might start a drain, then we are talking about >10% /hour, and this is much improved with Improved email and K9 and probably some other.

But please test some other modems as they could improve the power consumption while on 3G/HSPA.
[Galaxy S I9000 General] bokbacken:
So you have a stock ROM, 3E Recovery, it doesn't have these option, all special ROM:s out there have a different recovery with a lot of other features.

Why do you want to reset battery stats?

What battery drain problem do you encounter?
[Galaxy S I9000 General] manjee:
As Bokbacken said you have a stock kernel. If you have root access you can apply the script 'wipe battery stats' in Sgs Tools app.

Else you gotta flash your kernel, i'd suggest latest speedmod kernel.

Stock email vs Social Hub Push Email

Great thread and summary thanks Bokbacken.

The comments about "Samsung email" in this thread - I presume that refers to the stock email app that comes with the phone??? Any comment with respect to the "Social Hub" email app that comes as part of "Social Hub Push Email and IM (SEA)" under Samsung Apps. I am using this at the moment, I assume battery drain should not be an issue because it is push... anyone noticed anything positive/negative with this app?
[Galaxy S I9000 General] morgun007:
I will use SGS tools. I flashed ROM 3 times yet. And I think, that at least once I did not have fully charged battery.

I almost do not use my phone and it dont survive more than 40 hours. My usage is 30 mins of call per day and hour of doing something with phone during night I use sweet dreams to turn off data wifi and etc.

Battery usage show 39% Cell standby, 35 Display, 9 Phone standby, 8 phone calls, 5 wifi

EDIT: Battery level goes down especially fast between 100 - 75 percent.

I did not tweeked the phone at all yet. I just use setCPU and Screen Filter and have official 2.2.1 XXJPU ROM. I charge when I am below 20 % of battery and do not let phone on charger after full charge.

I do not expect 3 days from my SGS with regular use, but I do, when I barely touch it

In what way are other ROMs better? for example the speedmod kernel or Darky's ROM?

I don't even have lag fix. I heard it drain battery pretty much.
[Galaxy S I9000 General] manjee:
From what you report you have a normal battery life even if not a great one. Do you use 3G or HSDPA? Are you in 2.2.1?

A custom rom is useful if you want to customize your theme or get rid of samsung apps for example.

A kernel gives you the possibility to tweak the way android manages the multitasking, allows you to access advanced recovery (backup, root, bln, install unsigned zip...) and to apply lagfix. Ext4 lagfix is as safe as RFS (stock file system) and way smoother if you have a lot of installed apps. AFAIK it doesn't impact battery life.

Hope it clarifies things for you =)

I use pure GSM, start wifi if needed 3G just in very special situation. And yes it is 2.2.1 (Korean ROM)

Yes thanks. Maybe I will try the lagfix. I just heard, that it drains battery, but if not I will give it a chance.

I am satisfied with Samsung theme. I am just looking for longer battery life. I had nokia N95 and as you know with old phones I called more than 2 hours/day and had 4 days battery life :(

Anyway thanks for your help. I will wait for some super truper ROM and after my school semester I will play with it.
[Galaxy S I9000 General] existz:
Yea ext4 does not cause battery drain, I always use ext4-all + /system, (/system, /data, /dbdata, /cache all ext4) and it uses the same amount of battery as RFS, if not better using the way I have it tweaked.. it all really depends on the kernel.. for example I've used Setirons kernel with ext4-all and my battery drained in 10hrs, (the same as RFS)...but using Hardcores kernel I made it 24hrs with 30% left. It all depends on your setup, I even use some custom startup scripts that I made that gives me some extra juice (based on my needs), for example..I noticed my dns was changing every other minute so I made a script that sets it so now its not constantly changing)...alot of different things come into factor even with what file system your using
[Galaxy S I9000 General] Mparmpa-Nikos:
Yesterday I was talking about battery drain prob with a friend of mine,iPhone4 owner,and he suggest me to do the same as iPhone users did when had the same prob:Switch phone to flight mode over night and next morning check your battery percentage.

If have lost more than 1% indicates a running app causing battery drain.

I did it last night,and for more than 8 hours I saw no battery percentage drop.

So,I stop hunting "ghost apps" running on background and I assume that my case has something to do with my network.

HSPA off and only GSM and I'm in the hope...

[Galaxy S I9000 General] roisagi:
this is really unbelieveable:

i got the SGS to use its connectivity: my work push Email.

now, i have to stop Push email from time to time during the day to get 24 hours of work.

did Samaung make a mistake? is the "juice" on the device not compatible for its promary use?

do we need to switch to flight mode during the night??....

with Push + GSM only i still can hardly get 24 hours of use...

Not really experiencing any battery drain problems
[Galaxy S I9000 General] milro1970:
Hi to all.

I had similar problems like the ones described in this thread. Generally speaking there was no way to pass 24 hours without charging the phone. Even without using it at all (like over night) I've noticed in several cases 50% loss in battery in less than 7 hours. In one (and only one case) my phone went whithout charge for 44 hours. Posts where someone said that his (or her) phone could go on without charging for 5 days seamed to me mission impossible until... it almost happened.

After reading many of the posts in this thread I followed some of the advices and suprisingly after I fully charged my phone I saw the battery drop from 100% to only 75% after twenty four hours. Those 24 hours included 2 calls (20 minutes total), 5 minutes email reading, 30 minutes wi-fi on, received and read 3 sms, 5 minute browsing with opera mini, about 15 minutes "browsing" through the menus of the phone checking contacts or something and no 3G only GPRS activated.

Settings that I changed was:

1)disabled the use of wireless networks for locations

2)disabled entirely the use of 3g but I kept 2G on all the time

3)I disabled the autosync and I only did sync my phone once manually

4)configured my exchange email account to accept push notifications and disabled the sync entirely.

The result was outstanding. Of course I would like to have sync and 3G on all the time but for now I'm pleased because I know my phone can do with carefull use more than 3 days without charging... The only think that worries me is if this experience can be repeated at will... We'll see...
[Galaxy S I9000 General] Travel_Mate:
Sure it can be repeated. I've made the test for myself once - Packet data disabled and phone to GSM only, only phone calls, texts,few minutes video, menu and calendar browsing - 4 days with no worries, without turning the phone to flight mode or off during nights. BUT DAMN THIS WAS NOT THE PHONE I'VE PAIED FOR :D
[Galaxy S I9000 General] roisagi:
"BUT DAMN THIS WAS NOT THE PHONE I'VE PAIED FOR" - exactly:

we bought this phone in order to USE IT'S EMAIL, CONNECTIVITY, SYNC OPTIONS, AND 3G OPTIONS - we are getting a different phone than intended...
[Galaxy S I9000 General] webwude:
I've tested last week the battery consumption with airplane mode: drop off 10% in 8 hours... so i guess, it depends on what i am doing with the phone - yesterday, with heavy use of 3G / H and display almost the whole time on, after that winamp and music listening, i got a 50% drop in approx. 3 hours.

All the best,

ww
[Galaxy S I9000 General] milro1970:
I agree, but in my case the data packet was on (2G only) and the exchange email was pushing new emails immediately.. the other sync options was off. It is almost decent....
[Galaxy S I9000 General] amwebby:
I now have the phone set to go into airplane mode overnight and that, coupled with the wifi timeout hack has seen battery consumption consistent at 15 hours overnight and 8 hours during the day.

I applied the 3D gallery hack and that did provide a little of the above but Yamaha sensor use only dropped from 4% of CPU use to 3%, so not having a huge effect on battery drain. Switching of auto rotation, on the other hand, puts overnight drain at 20 hours and daytime drain at 12, a significant difference.

How is my phone now days?

I would say I'm quite satisfied with the battery life now, lets start with my current config:

I use my gmail account to sync with my personal outlook for calender and contacts, on top of this I also have one exchange account plus my personal imap mailbox.

Sync settings:

General, Background data and Auto-sync is ON

Gmail all sync ON

Exchange sync every hour, 3 day mail, Contacts and Calendar sync ON

IMAP sync every hour

Exchange and IMAP use AOSP email client

WIFI is switched ON

Network notification OFF

Advanced, WIFI sleep - When screen turns off (no hacks on this so 15min delay)

Mobile network

Use packet data ON

Network mode WCDMA only

Bluetooth OFF

Location

Use wireless networks ON

Use GPS OFF when not used

Use sensor aiding ON (is turned on together with GPS)

Display set to auto brightness

using Screen Filter set at 62%

Widget Beautiful Weather update every 4 hours

System Panel is always running Monitoring settings everything is ON (incl. High priority)

Active applications:

AdFree

BLN control

Dropbox

ClockSync set to sync every 12 hours when awake

TrueCaller

SMS Backup+

CalendarPad Pro

SwiftKey

Zeam launcher

Doc Theme V3 AOSP lock screen

The ROM is from Doc's and Stefunel's romkitchen.org using hardcore's K12K kernel, JPP modem and after the generation of the ROM I replace the email.apk from system with AOSP:s email.apk, replace libcamera.so so BarcodeScanner and other camera apps work without the original email.apk

I don't think I forgotten anything, the result for the latest 20 hours

First 7 hours is sleeping for the both of us. First high usage is 40 minutes of XDA browsing and some Angry birds, next big peak of 40 minutes is Andoku (soduko) and some XDA reading, then a 10 minute Angry bird and the last 50 minutes is gathering all the data for generating the diagram, I used Dropbox on the phone to sync the files to my PC so it's a few Mb data included and looking up all settings so it was active all the time.

Only 2 calls about 10 minutes total, 25 emails, no SMS!

If you like to try this ROM, go ahead, it's a no wipe version, so if you want to wipe, do a factory reset before installing the ROM, I take no responisibility of any of your data or anything else.

Bokbackens ROM

If you don't know how to flash a ROM from CWM, then go to another thread and learn, I would recommend Doc's or Darkyy's in the Development topic.

Less then 3 weeks ago (when I started this thread) my phone didn't last 8 hours in sleep mode on a full charge!

Yes I know my setup is not optimal for battery life, it's not supposed to, I bought the phone to use it.

We pay more than 500€ for a Smartphone, then we should be able to use it fully!

If I wanted an Idiot-Phone:rolleyes:, I wouldn't be here were the smart people hang out, would I?

I didn't start this thread to tell you how to turn off everything in your phone to get decent battery-life, I don't want to carry a zombie in my pocket, do you? :cool:

i am running JPY stock via Kies, no custom rom.

does the advanced/wipe battery stats appear only on custom roms?
[Galaxy S I9000 General] webwude:
Seems to be the "wrong" recovery mode.

Just use SGS Tools (@apply script: delete battery stats) or RootExplorer and manually delete the file (target: /data/system/batterstats.bin).

Hi,

I use HC kernel K12L

I want to use screen filter to improve my battery life.

But, every time i wake my phone, the internal task killer always kill screen filter apps.

Someone know how to configure the internal task killer so its exclude screen filter apps?
[Galaxy S I9000 General] zerozoneice:
what do you mean by "wrong recovery"?

i used vol.up+home+power, isn't there only one recovery mode? :)

my phone is not rooted, it's just Froyo 2.2.1 JPY via Kies.

SGS Tools works on non-rooted phones?
[Galaxy S I9000 General] zurchpet:
Stock recovery does not sport the wipe batterystats option. only if you use a custom kernel like SpeedMod, Voodoo and others you'll find the ClockWorkMod Recovery wich has this option.
[Galaxy S I9000 General] bokbacken:
To delete the batterystat you need root access, so it's a no go for you.

But what problem are you expireance? Why do you want to delete the battery stats?
[Galaxy S I9000 General] zerozoneice:
after i charge phone to 100% and remove charger, drops to 97 or 95%.

Also i need to keep every single sync and wifi/data connection disabled in order to squeeze 2-3 days out of one battery charge.

I suspect i need to recalibrate the battery and thats why i was following the post above and got stuck at "wipe battery settings".

For some reason my battery usage says the display is responsible for 75% battery usage but i have it at lowest brightness (+auto brigthness off) and i always lock the phone after i use it (powerbutton turns display off).
[Galaxy S I9000 General] ingineru:
You made my day :)

1. screen is the greatest power consumer

2. If screen is on is normal that it is the no1. consumer. So if you use your phone as a smartphone screen is always no1 in battery use

3. 2-3 days?? that is enormous battery life!

4. Why do you want to "squeeze" 3 days? is electricity that expensive?

5. Dropping to 97% is normal on certain roms.
[Galaxy S I9000 General] greasyguy:
I fixed the gallery bug, clear_thumbs_db.txt via SGS tools, turned off HSUPA and flashed the jpa wifi-fw. Wifi goes to sleep after 5 sec. black screen. Wifi always turned on. Autosync is turned on as well. All good for me now. :-)

Getting up to 2,5 days per cycle of normal usage.

Does anyone know if I need this WiFi fix with Darky's?

Thanks
[Galaxy S I9000 General] bokbacken:
ingineru is quite correct in what he says, and this calibration thing, to be honest I don't believe it.

Nobody has given any explanation on it, maybe we that reflash our phone every now and then get some problem with our battery life, and maybe deleting this file could help sort it out, but until someone show me some facts about this, I think it's coincident that give us good battery life.

But I invite anyone with the knowledge to prove me wrong.

If you want to squeeze a little more life out of you phone and you think the screen is too bright even on lowest, download screen filter, in the good to know page in the beginning of the thread you find a link to some measurements that lpy did so you could see how this affects current consumption, I think you could get about 10-15% extra out of your phone.
[Galaxy S I9000 General] zerozoneice:
hehe, stiu ca suna penal 2-3 zile dar sint castrate toate functiile :)

normally if i leave wifi or data connection ON overnight, with all syncs disabled, battery falls from 95% to ~70%. I would say if i use the phone "normally" (like i used the old one - iphone 3gs) i need a recharge every day...which kind of sucks.

@5: i use the stock 2.2.1 JPY from Kies, no rooting, nothing custom.

on the other hand, after rebooting from recovery mode i experience a lot of weird stuff: market didn't start (connection error), gallery and internet are crashing randomly, etc...i didn't have any of these symptoms before :(
[Galaxy S I9000 General] ludovicianul:
Hi guys,

Just to share my experience.

I have 2.2.1 JPY (installed with Kies Patcher). Didn't had any battery problems at the beginning. Not the WiFi bug (although the first thing was to set the WiFi sleep policy to "screen off"), not anything. Just awesomeness. After installing a bunch of apps (like almost 80) I've noticed the battery started to drain very quickly. Like 5% per hour in standby (of course, with all the data sync active). Initially i thought it was the Gallery Sensor bug, Facebook sync, etc, etc. The actual problem was FRUIT NINJA. After uninstalling it drains just 1% at most per hour with all the sync stuff: gmail, exchange, facebook 24/7. :)
[Galaxy S I9000 General] Greg767:
Google Maps 5 battery hog?

Hi All,

I was on stock JPO before and I had a decent battery life. Its hard to explain what is a decent battery life because it depends on many things, so I am going to refer to phone idle battery life.

So with JPO I had about 1% per hour (probably a bit less).

I've recently upgraded to JPY and installed Darkyy's v8.0 rom (wipe version) and there I saw a huge drain. Like 5 - 6% per hour and more when using the phone lightly.

What I did was:

Wipe battery stats

Not usig stock email

rebuild thumbs data

It got a bit better, but still a big difference compared to JPO (with 2.2).

Then I started to look into running processes and I uninstalled

3G watchdog

Screen Filter

in order to have the least stuff running.

And then I've discovered the "Rate Places" process that is tied to Google Maps which re-activates itself when I try to kill it.

IMHO this process eats a whole bunch of battery probably by data connection usage.

I tell you why I think it does.

This night I've turned off data connection and when I went to bed at about midnight I had 91% of battery, and at about 7 in the morning I had 86%.

And as soon as I turn data back on, it starts draining.

So these are my finds, I don't know if someone could tell if this is an important process, if it could be killed definitely but keeping Maps functional or shoudl uninstall the whole Maps app.

Maps can come hand time to time thats for sure so it'd be a pity not to have it.

And more important, check how does it behave in your phones. Is it the same?

Cheers

Guys, I'm telling you, Fruit Ninja is the bad guy. Unplugged for 17 hours, 77% left with Exchange, Gmail and Facebook + some usage. :)

Before, it would have been at 1% for sure.
[Galaxy S I9000 General] Greg767:
That's cool that you've found the cause of your drain, but I never had fruit ninja installed, so that can't be the cause of my drain.
[Galaxy S I9000 General] ludovicianul:
That's too bad. My drain was caused by the mediaserver process running continually due to some corrupted media in this game. Maybe you have something similar.
[Galaxy S I9000 General] bokbacken:
in that case you should be able to get it all working by adding a .nomedia file in the folders with corrupted media files.
[Galaxy S I9000 General] ingineru:
only 13 % gone in 17 hours with data on, auto-sync on ( background data ) ???

Are you sure?

Exchange sync consumes a lot of battery even if you do not receive very many emails....especially on 3g

Tested with system panel, exchange sync on cpu is always on 1%, with sync off is 0% ( phone left untouched for at least an hour )

I have question regarding Flight Mode.

Last night i put phone in flight mode at 1am with 60%

I wake up at 9am and phone had 47%.

This is my second test with flight mode and results are

almost the same. This is normal usage for Flight mode or no ?

I'm on Doc 7.9 Rom, SpedmodKernelK12L and XXJPY modem.
[Galaxy S I9000 General] zurchpet:
13%/8hrs ~= 1% per hour. I think thats pretty OK.
[Galaxy S I9000 General] amwebby:
I find if I put the phone in flight mode with auto rotation disabled the battery drain is 1% over 8 hours.
[Galaxy S I9000 General] Greg767:
An idling phone on flight mode should use way less. Like amwebby said, about 1-2% for 8 hours.

When I cut off only data connection before going to sleep, for about 8 hours of idling it uses about 6%.
