Thank you for clarification.

For example what do you think is wrong here:

- 26% after 17h 28m

- 93% display with 2h 31m usage

- 5% cell stanby

- 2% phone idle with 14h 57m idle time.

I calculated and the display ate around 1.19%/min .

Why that much? I found in this thread people with similar settings and their display ate 0.6-.0.7%/min.

When you say 1% drain over night, do you mean the percentage seen at phone idle or the percentage from the all battery ?
[Galaxy S I9000 General] melorib:
If you mean 26% left from 100%, then it drained 74% / 17h gives roughly 4% per hour

Mine has 26% now, 46% yesterday at 22:00, so 16h roughly 1.5% per hour, no calls, just loading apps, testing, playing, unloading, calendar, alarm, Wi-Fi...

- 84% Display

- 11% Cell standby

- 5% Phone idle
[Galaxy S I9000 General] -Loom-:
2 Minutes until the display switches off - that's a pretty long time.

I'm always using 30 seconds, and when I want to read something, I'm always touching the screen to keep it on.

The display is by far the biggest juice eater.

Try the latest speedmod kernel K12Q - the logs are disabled there, I think it id boost my already good battery life a bit.

Also very important: How good is your wifi and 3G/Edge/GSM reception? The weaker the signal, the more energy the phone has to use. However, switching off WiFi when display goes ark didn't have any effect on me.

It was mentioned earlier in the thread: SetCPU - This app clocks down the cpu on demand, from 1 Ghz down to 100 Mhz when in light use. This had a *very* noticable effect in the battery! I lost only 2 % energy over night in 7 hours, with WiFi on!

Also, it depends on how many apps are trying to sync themselves. Live-Wallpapers are also known to be huge resource hogs. Many other apps behave badly. Its a real mess to sort these out.

I can only advise you to start with a clean install, maybe Doc Rom, latest speedmod kernel with only the stock apps. Measure the energy consumption, then install each new app one by one, always measuring the energy. Its a time consuming task, up to the point where one could ask himself if its really worh the trouble and if maybe a full day of battery is enough anyway.

anybody using touchdown here?

attached you will find a very interesting juiceplotter diagramm from today. as you can see there are phases where is nearly non battery consumption, but otherwise it drains really fast. phone was on charger till 6:00 then I went to train station and was watching video from sd while sitting in the train. 07:20 I arrived at the Office and startet working. got and sent a lot of mails that got synced with touchdown. 13:00 at lunch I checked some private mails and was web surfing and was working again til 15:30 and went back home watching video again.after then the phone layed town for 3h with nearly non drain, till I startet to clean up my app list and made the screenshots. I had a BB Storm before that was more efficiant in sync process. Of course I had to charge every night too, but there was much more juice left before charging. usage profile was nearly the same sync 24/7 some browsing and 1,5h video.

I am actual on darky 8.1 with speedmod 12Q and ext4 lagfix. Had Voodoo5.2 and no lagfix before and think there was less drain, lagfix will the first thing I will revert, because the phone is over all some snappier, but was also ok without. Any tips on how to use touchdown more efficiant? But be mentioned turn of Sync is no option ;)
[Galaxy S I9000 General] lokhor:
I get very similar battery life to you and have tried every trick in the book. I have a feeling that some phones have a screen that uses more battery for whatever reason.
[Galaxy S I9000 General] melorib:
To avoid surprises, I am now only changing one thing at a time, and waiting to verify battery drain over night...

Yesterday I re-installed WidgetLocker, I want a different wallpaper in my lockscreen, and I paid for it...

Got home before 18:00, to get the battery to 20% before charging, I turned on Wi-Fi, Bluetooth and GPS, played 4 times a 300 + mb HD video with volume max, then connected the charger...

19:30 went to the sportsbar to watch Real Madrid, the battery was at 77%, made 3 calls, checked the time a few times, it was still 77% when I went to bed, a couple more time checks and alarm at 7:00, still 77%... :eek:

I thought the widget was wrong, but Mysettings and notification also said 77%...

1 hour later at work, it had moved to 76%, here are the stats... :rolleyes:

- 1% after 12h

- 39% display

- 35% cell stanby

- 17% phone idle

- 9% voice calls
[Galaxy S I9000 General] melorib:
I always lock the screen with the power button when I finish using the phone, 2 minutes because I hate it going dim while I am still using the phone...
[Galaxy S I9000 General] NeedBackup:
hello try this solution.

I have the problem of drain battery..but now its ok,

I'm currently on Froyo JPY and i dont have the drain of battery.

Do a full charge of your battery. And use your phone until this one will shut down.Active wifi, look an video, or play at a game in same time.

After you recharge it.

And get it off of the mobile. W8 a moment (5min) and plug into the phone, do a reset. And if you see at start an error of one app, that couldn't be load erase it.

And after that tell me if its fix the problem.

Thanks

now without 3G i loose less than 5% in one day.

Best regards
[Galaxy S I9000 General] zurchpet:
20 days without recharging?

I don't believe that. Unless you turn every thing off and don't use the phone anymore.
[Galaxy S I9000 General] Nismo:
Im on Voodoo 666 now, 30% drain per day.
[Galaxy S I9000 General] carlosrjbr:
Seriously, I'm running out of ideas.

Brazilian Galaxy S (i9000b), 2.2 and I still lose 3% per hour. I left it on airplane mode one night and I lost 1% over 6h, so going by this thread, it's not an app sucking cpu resources up. So it's either one using data or just the cell radio, but I can't seem to find out what it is...
[Galaxy S I9000 General] NeedBackup:
Actually disponibility time = 74hours.

Battery left = 73%

So (100%) * (74hours) / (18%) = 405hours => 16days. WIth the same utility.

Ok not 20days, but 13-16 it will ok

[Galaxy S I9000 General] Travel_Mate:
Everything :D
[Galaxy S I9000 General] carlosrjbr:
I think I've figured it out... Apparently the auto-brightness setting eats up a lot of battery... keeping it on manual seems to use up onlt 1.5% / hour

Has anyone had this effect?
[Galaxy S I9000 General] Nismo:
NEWS!

Gents,

I questioned myself during this week why I have a battery drain of 54% in 2 (!!) days.

Found the answer today in the news.

(Dutch)

T-Mobile: De hoeveelheid dataverkeer, veroorzaakt door het frequent aan- en uitzetten van de verbinding door 'apps' ('signalling'), wordt door de nieuwe techniek volgens Nokia-Siemens met 30 procent gereduceerd. Daardoor zou ook de batterijduur met 30 procent verlengd worden. "Een significante verbetering", aldus de zegsvrouw.

(UK)

Quote from T-Mobile: The amount of data traffic, due to frequent switching on- and off of all data connections by "apps" will be reduced by 30% following a new technique. As a result battery-live could be extended by 30%, a significant improvement. T-Mobile has introduced this new signalling this week in their Dutch networks.
[Galaxy S I9000 General] naenee:
Which new technique is that referring to though? Can you provide a link to the article?

What launcher screen is everyone using?

I was using LauncherPro and kicked it to the curb for ADW Launcher. Supposedly LauncherPro is a bit of a battery hog.

I also heard of Go Launcher. I just downloaded that, and will give it a try.

Is the stock TouchWiz Launcher definitely the best for battery life though? Just curious, and if so....is it minimal and not even worth discussing?

On a side note I'm Using Ultimate Juice (aka...Juice Defender Pro) and also AutoKiller Memory Optimizer....free version. I like both of these.
[Galaxy S I9000 General] Nismo:
Forget Autokiller. Killing an app and starting up consumes power, best is to use a big RAM kernel and leave the apps running. Apps in memory do not consume power ;)
[Galaxy S I9000 General] melorib:
Not me, always on auto, 12h 1%, overnight, but with 3 phone calls...

Using GO launcher...
[Galaxy S I9000 General] naenee:
Thanks. It is not certain whether it will yield the results they hope for then and after searching a bit it will only help when having 3g enabled.
[Galaxy S I9000 General] Nismo:
In any case, it strengths my feeling that the battery thing is mainly a GSM-data issue. This was already in the past a problem and still is.

When I am abroad visiting an other country, I can last 4 day's. All communication 24/7 during visit is done via WiFi. Also when I work at home I see the same (GSM-data is shut down).

What I also notice is that my phone (battery) gets less hot when data is engaged outdoors.
[Galaxy S I9000 General] brack11:
I'm also into this research, just installed go launcher yesterday and it looks good but can't figure how it is with battery, colours in twlauncher look better but it maybe because of colourless dock of the go launcher. Also I like pitch com in app drawer of twlauncher. If go launcher would improve my battery life I would stay with it. Any one can share experience?
[Galaxy S I9000 General] carlosrjbr:
Yeh, apparently it was just the placebo effect or something else. I'll test out switching to 2G only, but I guess I'll have to agree with it being a GSM / 3G data thing that hogs battery.
[Galaxy S I9000 General] kraksen:
My findings so far.

The "real" battery drain happpens when idle.

Scenario:

- Charge till 100% before i go to bed.

- Leave it on, while asleep.

8 Hours later:

- Battery down to 52% (!)

- Battery reports, that the screen has eaten 38%, of the drained 48% (!)

How can this be ? Without screen even being on (the time reports, 2-3 minutes, with screen on )? How can 2-minutes screen usage eat 38% of the total drain ?

The problem started with stock 2.2. On 2.1, my battery could last a few days easily with moderate using.

I have now spent monts with stock roms, modded roms etc., read i don't know how many battery threads, done the battery calibrations (in all variants) over and over again, nothing..

VERY frustrating, when others users reposr 3-5 battery loss, during nighttime, compared to my 48%..

I am thinking, does the screen use battery even being of, since it reports that the screen has eaten almost half of the 48% drain during nighttime idling ?
[Galaxy S I9000 General] kraksen:
Interesting.. Actually i remember noticing this one, but never followed up on it.. My finding is, that the whole battery drain is linked to the screen somehow (se my above post), so i will try being on manuel instead of auto adjust, and see what happens..
[Galaxy S I9000 General] NISMOFO:
I heard this about the traditional memory killers. This one uses the stock android system to free up ram. I've always been weary of flashing a different kernal because I thought that would eat up battery.....backward I have it all backwards.
[Galaxy S I9000 General] webwude:
The drain seems really depend on the 3G / GPRS Data usage... as I drove this morning out of my country, the drainage almost immediately stopped and stayed for hours on the same percentage of battery amount.
[Galaxy S I9000 General] t-jet:
oops wrong thread
[Galaxy S I9000 General] Lancey:
Try Doc's Rom kitchen with Speedmod kernel. http://romkitchen.org

Before flashing, clear cache and disable all lagfixes if you have them on.
[Galaxy S I9000 General] basti107:
i have nearly the same problem. cannot figure out what it is...
[Galaxy S I9000 General] melorib:
When I disconnected mine from the wall it had 81% battery, 21:30...

It still is 81%... :cool:

All I do is:

-Phone on, want to be able receive calls and SMS during the night

-Wi-Fi, GPS, 3G, Bluetooth and Auto-Rotate OFF

-Wi-Fi sleep policy = When screen turns off

-Power saving mode OFF

-Back up my data OFF

I have always ON:

-Battery widget

-Calendar widget

-Analog clock widget

-WidgetLocker (to be able to use different wallpaper on lock screen)
[Galaxy S I9000 General] basti107:
ok, last try. i ordered a new battery :/

//edit: received it, loading to full while phone is off. then goto recovery-menu and delete bat-stats. hopefully there was the fault. -tried everything. it's really my last try.

//edit2: damn. - same problem. i do not know what i am doing wrong...

mA Tests

Speaking of 3G, I did a couple of quick tests today...

To disable/enable HSDPA, I used *#301279# in dialer.

XiiaLive app, running a 128kbps mp3 Shoutcast stream, w/ screen off​

WiFi [WiFi On] : ~123mA

3G [WiFi Off, HSDPA Disabled, 3G Auto-fallback] : ~243mA

HSDPA [WiFi Off, HSDPA Enabled] : ~243mA

I can't test Edge or any other mode, as they're not used on my carrier. There are claims that HSDPA uses more power than 3G, and although it isn't the case in this test scenario, I can't say for sure in other cases, such as idle, different networks, etc.. As usual, YMMV.

Someone asked for some pics a few pages back...I did a few:
[Galaxy S I9000 General] holgalee:
How do you guys/gals know which apps/processes eat up your battery life? Can you explain to me how you monitor, or which apps you use to find out? And what does the Bokbackens ROM do?

Sorry for the newbish question. I'm a tech 'bimbo' and can't make head or tails out of the wonderful tools out there.
[Galaxy S I9000 General] naenee:
Settings, Battery Manager, then click the battery to see usage, sorted by device/app.
[Galaxy S I9000 General] morgun007:
Hi what is the best ROM now?

I call round 1-2 hours/day, maybe hour of using the phone per day, synchronizing with inbuilt gmail app and k-9, facebook, agenda widget with gcalendar.

-maybe I can somewhere limit synchronization for once per 5 minutes or even more, is this possible and could help with battery??

I use only GSM so edge for data, have black wallpaper, XXJPY ROM, I barely use wifi and 3G. I also use screenfilter.

I will try application Timelines for finding for comsumes my battery.

@naenee: I do not have battery manager in settings. I also didn't saw any drain logs devided by applications.

I saw lpy's measurements it is awesome man. Thanks
[Galaxy S I9000 General] holgalee:
Thanks. Do you mean my phone's settings? I don't see battery manager.
[Galaxy S I9000 General] dhiru1602:
Is there any problem with the display driver or Voodoo Color that is causing any battery drain?
[Galaxy S I9000 General] naenee:
Yup, I meant phone settings. Alternatively, if you are using an older version of android, try Settings, About, Status - I seem to recall there was battery info in there too.
[Galaxy S I9000 General] Vitz1988:
Thanks for this. Recalibrating my battery solved the issue entirely. :D
[Galaxy S I9000 General] borchgrevink:

[Galaxy S I9000 General] basti107:
maybe found the drain

Found this in another thread:

This could be the reason of my sleepless nights :)

testing right now. (removed my sandisk 16gb)
[Galaxy S I9000 General] EarlZ:
Probably doing several charge and discharge cycles, as not to confuse anyone deleting the battery stats does not recalibrate the battery, the battery stats is for the battery usage HISTORY thats why the phone keeps a file on what WAS using the battery, that data can be viewed under test mode.
[Galaxy S I9000 General] thecresta:
Ok, got a new record!

Docs 9.1.4 JS3 and Hardcore K12S 500Hz.

Overnight, between 00:45 and 7:15 - dropped from 68% to 30%!

Phone screen was off, Wifi was on but the correct "Never when screen off" setting. No GPS, BT - nothing else was left running apart from data.

In battery history in SGS tools prove hardly anything is running, low cpu usage, wifi on 20% running (but 65% on).

Strangely my alarm came on at 7:15, and between then and 9:00 the phone only used just 1-2%! So as soon as the screen came on it went back to normal battery usage!

However, from then 9:00 to now (11:56) it's dropped from 28% to 10%.

I HAVEN'T EVEN USED THE DAMN THING OTHER THAN TO CHECK JUICEPLOTTER!

It's doing my head in!
[Galaxy S I9000 General] amwebby:
Even though you have wifi set to turn off when the screen is off it still.takes 15 minutes to do so. Also packet data, if left on, will cause even more battery drain. I found that turning packet data off unless I need it and setting the wifi sleep to 15 seconds, using the feature in One Click Lag Fix (but not the OCLF itself), lengthened battery life from 8 hours to 15 overnight. It is also best to set wifi sleep to "Never when plugged in".
[Galaxy S I9000 General] lpy:
Got widgets going? I've found that some can be quite buggy when it comes to battery life. They might do anything from leaving the Wifi on to preventing the phone from entering deep sleep, etc... maybe remove them all for a night and see what happens.

Also update to the latest SpeedMod.
[Galaxy S I9000 General] morgun007:
Please what is actually the best ROM?

At least guys please tell me which ROM you use or consider good/best

And How could I find out, which application do not allow to move to standby over night?

I have round 10% drain during night, what is not so bad, but it could be better.

I use application Sweet dreams to turn off packet transfer during night.
[Galaxy S I9000 General] Don MC:
I'm getting some real annoying problems. I have WiFi policy set to always on. Whenever I leave home (and thus my home wireless network), the phone starts heating up and draining battery like crazy. Turning WiFi off stops the draining, but that's not a fix to my problem.

I'm on Doc ROM 9.1.4 (although the problem was present with 9.1.3 too), various kernels (they make no difference) and various modems (they also make no difference).
[Galaxy S I9000 General] KennyLegend:
Im using an app called "tasker" to turn off my data transfer when my screen turns off and vice versa. i had 1% drain overnight last night (bout 7 hrs) .

you can also use it to put your phone into flight mode when your sleeping . . and save some serious battery.

Quick update:

I tried each of these tests for at least 1 hour. Data is 'Auto GSM/WCDMA' unless specified.

Flight Mode On

* No noticeable battery drain

Wifi & Sync on and Data off

* No noticeable battery drain

Wifi on and Data & Sync off

* No noticeable battery drain

Wifi & Sync off and Data on

* Between 3% and 7% an hour (absolutely no use, screen off)

* Up to 15% an hour (very light use - checking gmail, facebook and android system info / juiceplotter)

Wifi & Sync off, Data on, ALL app and service traffic blocked by DroidWall

* Between 3% and 4% drain an hour (absolutely no use, screen off)

Wifi & Sync off, GSM only Data on, ALL app and service traffic blocked by DroidWall

* 0-1% drain an hour

It's looking like WCDMA/3G Data enabled is causing the idle drain, even when there's no data being transferred.

Anybody have any ideas what might be causing this?

Thanks in advance :)
[Galaxy S I9000 General] Khoral:
Maybe it's when Google connects to your phone to spy on you ? <_< >_>

*Conspiracy Theory*
[Galaxy S I9000 General] KennyLegend:
have you tried "tasker"?

ive mine set up to turn off all data after 10s if screen is off.

also try "superpower".also allows you to turn off data or switch to 2g when display times out.

this didnt work very well for me - wifi was slow to come back on etc.

i would recommend tasker though. it costs about $4 but well worth it for the amount of stuff u can use it for.

Sent from another GALAXY
[Galaxy S I9000 General] thecresta:
Hi, thanks for the advice, I'm playing with Tasker now - this app is amazing! :D

So far I've set it to turn off data after 20 seconds of display going off, then turn data on every 30 minutes for 3 minutes while the screen is off (for auto-sync). Then turn data back on again when the screen is on.

Doesn't really fix my problem, but at least I'll get something back (providing it isn't a massive data hog itself :p)

Superpower didn't work well for me either - WiFi randomly fell into an endless loop when the display was turned back on (Searching > Connecting > Disconnected > Searching) even when no WiFi options were enabled! I had to keep rebooting to get it to work. Apart from that it is a great app.

Update:

Still getting 20% drain overnight (8 hours) even with tasker running. I'd removed all widgets and turned off all background tasks off too. Think some extreme testing is in order - complete wipe and work from base rom and install apps slowly until I find the culprit. Not going to be fun.

I have the strangest feeling it's the battery though. If I install a new battery I take it the battery stats get reset automatically?
[Galaxy S I9000 General] basti107:
...and how do i find the killer?
[Galaxy S I9000 General] KennyLegend:
check whats running from task manager and disable them one by one with reboots. slow but Im not sure of any other way. its more than likely a widget.

There is the problem. I do a clean flash with odin even with repartition. No apps installed. Simcard in or out. Tried every possibility. Nothing.
[Galaxy S I9000 General] beppez82:
I find that to solve strange battery drain is to charge the phone when it is off all the night than flash a custom rom with wipe erasing cache dalvik cache and battery stats or flash a samsungs one with Odin with 100% battery. If u have an app that eat ur battery there's an app called osmonitor i think that help finding the eater...

Hope these can help.
[Galaxy S I9000 General] KennyLegend:
maybe you just need to re-calibrate your battery then . drain fully. charge while off. when full, take out battery, stick it back in and put it back on charge. boot into recovery and under CWM wipe battery stats. wait till 2-3 battery cycles before you determine your battery usage /drain.

if this fails, try another modem. especially cause you have no apps installed.
