Overnight last night i lost about 3% on wifi. Before I would lose about 8%.

Depending upon the rom and modem used the overnight drain is between 1% and 5% with Mobile Data OFF WiFi OFF GPS OFF .

If you are asking your WiFi to continually search it will drain .

Wifi sleep policy when screen turned off is best .

[Galaxy S I9000 General] cow_like_object:
yeah of course, but only if your mobile data stays off. turning everything off would obviously make battery drain minimal.

the main point of what i was mentioning was googletalk. leaving googletalk on caused my battery to drain 2 times more.
[Galaxy S I9000 General] thecresta:
Ok, I messed up, but in the process I've found the culprit!

Last night I drained the battery completely, and charged it powered off.

It was at around 30% and I decided to turn it on. Straight away on the task bar it said it was 73% charged!

So I turned it off again, and powered off it now said it was over 70% charged, even though a minute earlier it said 30%.

This morning I looked at juice plotter, and it had recorded that it had jumped from 35% to 73% in under 1 minute!

Now to get that 38% of charge back... ;)

Lakigucci's battery test.

Post #1

Post #2 (this post)

Ok guys i did some testing with (i think) amazing results.

What am i running/What are my settings:

*Kernel: Speedmod K13a.

*Rom: Liteϟning Rom V3.0.

-------------------------

The follwing battery tweak's where activated in the Speedmod kernel.

*IO scheduler + Remout noatime (R)

*Kernel VM management (R)

*Kernel scheduler (R)

*Misc battery tweaks (R)

Lagfix =Off

-------------------------

Synchronizing = Off (Won't fetch mails from Gmail unless manually, Won't connect to Gtalk).

Screen Brightness = Darkest setting (Automatic is overwrited so Off see screenshot Energy Widget).

Switched off 3G (mobile internet, switched on when needed).

Wifi = Always On (WhatsApp cant receive msg's offcourse when its off).

GPs= Off.

(The stock Energy widget i use)

Automatic Screen rotation = Off. (This turns off the proximity sensor wich also uses battery/cpu).

Cleanup cash regularly with the app Fast Reboot.

With these settings i managed to get a battery usage of approx. 3,7% per hour overall (idleing and active usage).

I had 65% battery left after 28h after the last charge.

Ill post a screenshot soon to backup my post ;).

I will fully charge the phone, then let it run empty totally and make a screenshot of the battery status screen.

[Galaxy S I9000 General] lakigucci:
I do not have any comparisment to compare it with, so ill do this test, en then the test with misc battery tweaks off to see if it make a difference.

It would be nice to have an app wich drains the battery quickly wich a sort of looping benchmark to test battery durability, so i do not have to wait 2/3 days with results ;).

Anyone have notice of such an app?
[Galaxy S I9000 General] thecresta:
For comparison, here's my JuicePlotter graph for the last 9 hours:

Mostly idle, with some random checking of Gmail and Facebook. Also finding the address of a store and using GPS and maps to find it (11:30 to 13:00).

And heres where I think it's all going wrong. See around 00:45 - this is when I turned the phone on while charging, then turned it off, then on and off again:

Hope to post better results soon :)
[Galaxy S I9000 General] lakigucci:
Running JuicePlotter now, lets see what it does for me and my settings ;).

Started now @ 93% battery.

Will this app run in the background?
[Galaxy S I9000 General] thecresta:
I've managed to get my phone to drop from 52% to 0% in under 3 hours by keeping RunKeeper active (polls GPS at regular intervals), WiFi enabled and transferring 1-2gb files backwards and forwards between my server and my phones SD card, while having brightness at highest and screen always on.

I'm sure it'll take longer than that on your phone, though ;)
[Galaxy S I9000 General] lakigucci:
Thats a good option indeed.

Ill try that maybe later.
[Galaxy S I9000 General] ingineru:
Use SetCpu for that, go to Info -> stress test, it will keep the cpu at 100%
[Galaxy S I9000 General] lakigucci:
I will defenitly try that.

I told you guys i would post my results when my battery was empty.

I gotta tell u unfortionatly, u have to wait a bit longer, its still running since yesterday ;).
[Galaxy S I9000 General] basti107:
i really could throw my i9000 away :(

i use it for 1 week now without playing around (or flashing roms/kernels)

i still loose 3% battery per hour over night. (data & wifi disabled; no apps installed)

my phone seems broken... is it really true that people loose about 2% in 7 hours?
[Galaxy S I9000 General] muffmaster:
Seriously?! C'mon man, there's worse things in this world than losing a couple % overnight!

I have some battery issues. I'm sure things will work out eventually, if I just have some patience. There's smart people around, working on this!

Try having for example your netbook powered on, just being idle all night. How many % do you lose?!

Take a deep breath my friend!
[Galaxy S I9000 General] JJEgan:
my phone seems broken... is it really true that people loose about 2% in 7 hours?

Yes or even less overnight 1%-4% , But on the other hand last night i dropped 74% for some reason .

Average Smartphone battery recharge is every one and a half days .

Wrongly charged new phone will lose more initially .

[Galaxy S I9000 General] thecresta:
A couple of updates:

13th Feb:

At 20:00 I experimented - I turned the phone off, plugged the power cable in, turned it back on and unplugged the network cable. The battery shot from 15% to 44%, then plummeted again.

14th Feb:

I have no idea what happened between 19:00 and 23:00 - there was no change in how I was using the phone (ie: not at all ;))

Quick question (mainly for those without battery problems) - how long does it take your phone to charge using the mains charger (not the USB to PC cable)?

Mine takes just under 3 hours to charge from 0% to 100%
[Galaxy S I9000 General] muffmaster:
thecresta: Hmm, that seems all wrong to me... :/

Have you used the different techniques for wiping battery stats?

How long ago since you flashed?

Did you use a wipe version?

Tried other modem versions? The one you're using drained loads of battery for me. However this depends on your operator/location.

Are you sure there's no background services/apps draining battery?
[Galaxy S I9000 General] thecresta:
Hi,

The method I'm using at the moment for draining is:

1. Charge to full while on

2. Reset battery stats in recovery

3. Turn on and drain fully to 0%

4. Charge phone fully while off

5. Turn on phone and drain to 0% again

6. Charge again fully while switched on

I've tried the above three times now, and I've been repeating steps 5. and 6. for the last few days but I'm not noticing any improvement, just anomalies like those in the graphs in my previous post. Is there another method of draining other than the above? If so could you point me in the right direction please :)

I last flashed last week, but I've been through 2 Docs JS3 ROMs and 1 Darkys ROM in the last few weeks. Each had the same problem. I always do a full wipe before I flash, always have done since my Windows Mobile days. It's a bit of a pain, but at least I can be sure there won't be any problems later on down the line ;)

I've tried JPY, JPP, JPD and finally JP5 modems (I'm on Vodafone UK, so this should be the ideal modem for me), none have made any difference :(

I've run the ROMs from 'stock' too, without adding any extra apps and still get the drain. I've tried a number of process monitoring apps but can't see any processes that are acting abnormally. The battery stats (which I access using the secret code) do not show anything that is causing excessive drain.
[Galaxy S I9000 General] dw_bobby:
Hi Everyone,

SGS with Darky's 9.2 extreme here, heavy battery drain, 10 hrs of moderate use at best.

Went thru a bunch of modems, JPU showed a mild improvement in battery life (12 hrs) so hanging on to that at the moment.

This morning i installed Juice defender on a full charge (99%) and i am now 7 hrs moderate use at 78%!!!!!!!!!!!!

I cannot believe my eyes. I have no idea what this thing does but it does it really good.

Can anyone help me figure it out?

ideas welcome.
[Galaxy S I9000 General] JJEgan:

JuiceDefender

It extends battery life by intelligently managing the battery-draining components of Android devices, like 3G/4G connectivity and WiFi.

Fairly simple answer rom = bad battery drain JD manages battery drain better than that rom .

[Galaxy S I9000 General] KennyLegend:
It turns off your data connection mainly. That's what i find drains my battery the quickest. I use 'tasker' to turn mine off when the screen is off.

@thecresta

Your network strenghth bar...how does it look like? How many bars are full? If you are on a location where is not good network avalaible, of course you will get high drain because your phone tries to make a good connection.
[Galaxy S I9000 General] Don MC:
That's about right for the Samsung charger. I also do have a Nokia 1200 mAh charger that takes about 1,5h to charge the phone.
[Galaxy S I9000 General] borayman:
omg...i get confused every time i unplug the charger.....

is it really true ??? or just a explanation for a bug...

how can a fake number proling the life of a battery
[Galaxy S I9000 General] thecresta:
Thanks ;) At least I know it's getting a decent charge now...

*** Ok this is totally screwed up now! ***

Plugged charger in at 35% remaining

Turned off.

Battery indicator said around 60-70% remaining.

Turned on.

Notification bar says 17% remaining.

Turned off

Battery indicator still says 60-70% remaining!

Turned on

Notification bar says 69% remaining!

All in the space of 5 minutes!!!! IM GOING MAD!!! :confused:

3G/H it's 1 bar at home, 2 bars at work, 2G it's 4 bars at home, 3 bars at work. But I get the same drain regardless of whether its set to HSPDA or GSM.

To be honest, I'm fairly confident its a battery problem. Either the stats are WAAAAY out, or the battery itself is knackered.

Screenshot for fun ;)

How did i achieve this?

-3G/GPRS Off if not used.

-Wifi Off when not used.

-Screen Rotation Off when not used.

-Screen brightness on darkest setting.

-Battery tweaks activated in Speedmod K13a

-Lagfixes Off

-Cleaned cashe with Fast Reboot after every time i unlocked my screen.

-Synchronizing Off (Manually retrieving mail).

And well, its still running. :cool::cool:

please, this is my last chance, does someone has an official link or can verify there's a problem?
[Galaxy S I9000 General] HM.Carbide:
3 Days are possible with a view things only (stock 2.2)

- WIFI standby if screen off rule

- auto synchronize off

- 2g instead of 3g
[Galaxy S I9000 General] dw_bobby:
Juice defender indeed just turns off data. That means no sync, no IMs, no nothing, which pretty much defeats the purpose of all the smartfone thing...:)

Now i am using 3G Watchdog to spot the apps that eat data and will try to find a way to elimate those that are not needed.

Will post any relevant results.

Thanks guys.

lakigucci:

Wow, that's some nice improvments! :)

I the same ROM you are running, but it didn't stop my battery from draining... :(

I'm using Insanity ROM now, and it seem better for me and my battery. However, not perfect.

Do you have the Misc Battery tweaks enabled/disabled?

Regarding Fast Reboot cleaning, do you run it manually every time you unlock the screen? Sounds a bit funny to me, but I'll try it a bit as well... :)
[Galaxy S I9000 General] thecresta:
Update:

My phone has been running on battery for 35 hours solid, and it's been at 9% for at least 3 hours now!

Although I've hardly used it, this is a massive improvement.

My process (all with MAINS charger, not USB from a PC!):

* Back everything up ready for a ROM wipe install

* Charge battery to full when off

* Discharge fully

* Charge when off until you get the 100% notification

* Leave it another 2+ hours

* Turn phone on

* Unplug charger, plug charger back in wait for 100% notification (takes a minute or two)

* Unplug charger

* Turn phone off

* Plug in and charge to 100% notification (takes a minute or two)

* Keep charger in!

* Boot to recovery

* Reset battery stats

* Clear Dalvik cache

* Format data

* Flash New ROM (in my case Doc & Stefs 9.9.6 Kitchen with Hardcore kernel)

* When flashed unplug charger

* Don't install any apps for the first few hours, see how it goes!

Going to drain to empty and do a full charge with phone off, then turn it on with the charger still in until I get the 100%, then I'll start using and charging it as normal and see how it goes.

Thanks for your help everyone, I hope the above is useful to someone! :)

After 12 hours I started installing Apps, and did some basic syncing of contacts, installing accounts, checked a few Pulse feeds, set gmail up and running again with Autosync running constantly. I left Wifi (30sec timeout) and Data (2G only) running near enough the whole time. Did a small amount of browsing, checked my Facebook occasionally, but to be honest I didn't do that much with it. Oh, and a few short (<5minute) calls.

Just getting it to last more than a day is great for me

You say that, but no other method I found worked...

BTW, took it off charge at 06:30 and lasted until 18:45 the next day.

No battery management widgets.

I have almost opposite experience with setcpu - it eats about +3% of battery at the night, specially if I have any single profile enabled. Tried it several times with different versions of firmware and kernels.

Well, my personal experience is that tegraks kernel saves the battery for me with no other tweaks. Looks like simply stock kernel is the best on battery, and tegraks kernel is not override stock one.

THANK YOU!!!
[Galaxy S I9000 General] Nismo:
Tested SetCPU last week, one big drama... Normally I burn +/- 40 % in 24 hours, with SetCPU it was 100% in 24 hours. I am back to Voltage controll, 1200MHz max controlled by Voodoo 666. I have SuperPower running and switch of the phone when I am asleep.
[Galaxy S I9000 General] Don MC:
Yeah. I was under the impression Android has CPU stepping as a built-in feature. Thus SetCPU would be redundant. Am I wrong?

My battery lasts me 3 days. I also do use my phone as a smartphone. 3G and WiFi are on 24/7. Email & Calendar are on auto-sync (push). Doc ROM 9.6 and Speedmod K13A kernel. Lagfix and tweaks are on. So I am in no way paranoid about my phone and I never put it in airplane mode etc. Only "battery saver" app I do use is 'Auto WiFi Toggle', which turns off WiFi whenever I'm out of range (otherwise it would eat my battery in a couple of hours). When I return home, it turns WiFi back on.

I am happy with my 3 days. Decent for a SMARTphone. As a sidenote, I do not spend hours on end talking on my phone. Some days I can go without a single call. I'd say very seldom more than 15 minutes of talk time a day. But I read plenty of emails every day and check my Facebook etc.
[Galaxy S I9000 General] lakigucci:
Yes did had all the (R) tweaks enabled including the misc. battery tweak.

Regarding to Fast reboot, i did that everytime i lock my screen after i used the phone. So no un needed apps are draining my batt. while idling ;).

Edit: I however noticed that 3G is draining most battery.

With WiFi On en Sync On im getting best results qua overal usage.
[Galaxy S I9000 General] madmax916sps:
Hello,

I buy my Galaxy 3 Weeks ago and before it Drain much Battery,

after some time i play with it ( flash roms, kernels themes and take Information about Battery Drain) it takes 2-3 days of Medium use if the Battery takedown.

My settings are

most Dockitchen Roms, JPY or UGJL2 Modem, 3G on only (no H+), Hardcore Kernel with Lagfix on or Tegrak with Onenand.

The most reason for battery draining problems ist that noone Callibrate it.

if you do it 4 days -> 100% (Delete Batterystat file) ---> hardusing to 0% (Phone shut down... i allways try to power it on again, sometimes it take 2-3 Min on until its Dead ^^ and than again charged it full, i plug in the powercabel and turn the phone on direktly (use Flymod for faster recharge, or normal but it takes a bit longer)

if you do it like this you can see very fast the differens

:D
[Galaxy S I9000 General] adamge:
madmax, please explain "Flymod."

One thing I've noticed is that, even in Airport mode overnight, my battery drain was the same as during daytime. Last night I removed some gadgets from the home screens, and overnight it used 0% battery drain. The two I removed were JuicePlotter and MIUI Music.

If a battery is draining in Airport mode, then some useless process must be wasting resources.
[Galaxy S I9000 General] guika:
Hi all

I vebhad same problem like you guys. And my experience was that with original rom it was above normal slow and battery was normal 1 day for me.

With darky rom 9.1, 9.2, 9.3 beta i had issue with wifi.

I could achive 2 days with normal usage but with wifi i killed my ohone in some hours. I always did the calibration and wait 3 or more cycle charging but the problem was the same. Also every time i made wiped install. Than i started to change kernel to speedmod instead of voodoo i helped a quarter day with the same program and usage. I started to keep that this is normal. Today i tried doc kitchen with speedmod kernel evry tweak on (r and o) and my screen is on wifi on played downloaded rwbooted hacked so it was in my hand since 8 hours and still got 31. I ve checked the wifi driver but the size of the directory is the same like in darkys. I am in hungary and i am using zsjpe modem its axting great here better signal and battery and thw gps is also fine.

I suggested to my collage he has sgs stock version to flash speedmod kernel only lag fix and r tweaks on and hs could reach 3days with easy usage.

What i have noticed that my phone use less cpu time with andftp in doc and more cpu time with darky. Interesting i didnt understand it as well why. Also i could not understand why wifi or 3g downloading eats 30 cpu time.

Setcpu

I tested it as well and its acting like the android kernel. The normL kernel is also switch back to 100mhz when screen is off and phone is sleeping. And put 1ghz when u need it.

In my idea we could earn really much if we could set cpu speed to application. I tested set cpu to put 400mhz while angry birds playing or watching divx. It worked. But with on demand version or with the kernel these medias using demands so 1000mhz.

If some could write app for it that would be great i think.

Generally here some numbers for screen from xda

But i forgot the brightness level.

Screen on it use 170mah so it meana only with screen an 1500mah accu could feed ut for ~9h.

My exp that there are really differences on sgs same versions and in modem and wifi drivers kernels and in roms. Also there are juicy apps.

I am using droidwall with that i am blocking a lot off apps from the internet.

I will agree with the general sentiment that the more you mess with the phone the more you "confuse" it as far as battery management goes.

As I type this, unplugged for 34 hours, 66% battery left, 3.897V, 23.0 C

it gets better with age.

[Galaxy S I9000 General] salivaman:
after clean install don't do anything - no installing of apps or even log into google account. then test the battery drain.

from my results battery drain is always normal after a clean install (1-2%/hr with 3g on idle), but after a few days and installing several apps the battery drain will always and every time increase dramatically, perhaps more than 3%/hr and sometimes up to 5-10%/hr even only idling. i have given up on how fail the apps are coded in terms of battery optimization or how ****ty android manages its background resources, and just resort to using green power to switch off wifi and 3g when the display is off. if wifi and 3g are off, i get a standby drain of 1%/9hrs, which is nearly 1000% battery savings compared to 3g on all the time for idle time.

not to mention when 3g and display is on, drain rate is around 1% for every roughly 2 mins of display on, which is pathetic considering I can only use the screen for only around 3 hours straight (not even considering standby time) before the battery goes flat on me. it doesn't matter what modem I use the drain is all the same.

but i think what's most important to note is when posting battery results people should always state if 3g/wifi is on and how long the display is used (don't post the stupid useless "battery use" which only states the % of the display used). anything without these 2 information is plain unhelpful and doesn't contribute anything.

sorry for the font size but i am seeing way too many people who post battery results yet without the most crucial data. this phone setting discrepancy causes a lot of confusion as to why some people's phone can last for days while others can barely last through a day.
