Sadly Im going back to JPY modem. On JPP I have bigger drainage and on wifi battery drains 1% for 2-3 mins when using the internet.

Sent from my Samsung Galaxy S

After two days I can report that disabling Auto rotation has definitely worked for my phone and even improved the battery life with the third-party battery getting 15 hours and the Samsung battery clocking in 20 hours.
[Galaxy S I9000 General] razzda:
Just wanted to see what happens if everything (almost) is switched off and leave the phone be. No calls, no SMS.

Stock JPY, Voodoo 5.0.3.

WLAN off

Data (HSDPA) on

Bluetooth off

GPS off

Auto rotation off

Auto sync off

At T=48 hours after full charge, I still have 44 % left. I only switched on Wifi for 10 minutes whilst surfing, resulting in a 7 % drain.

Hello, here is my personal experience with 2.2.1 and battery drain:

two days ago i loaded into my i9000 the 2.2.1 (JPY) trough kies reg hack, wiped to factory reset, rooted the phone with SuperOneClickv1.5.5 and restored the backup trough titanium app; i experienced high battery drainage keeping wifi on (connected) and data on, the drain was about 1% for 2-3 minutes.

I tried changing the modem back to JPP but nothing changed.

And...yesterday afternoon i wiped the phone to factory and loaded JPY trough odin: the battery drain is very good! Keeping wifi on and data on during the night the battery drain was about 0 - 1% (still 40% this morning).

I haven't rooted the phone, it's the stock firmware, no titanium restore. GPS on, bluetooth off, autosync on. Wifi standby policy set to never.

This evening i will charge the battery to 100%.
[Galaxy S I9000 General] bokbacken:
Hey, this is so great, in other words:

If I don't use my phone, I can (not) use it for almost 4 full days :D

This is a nice reference though regarding "background" drain, if there is anyone else willing to not use your phone during 48 hours, please report your findings also.

Thanks a lot razzda, can't imagine the feeling to keep my hands of the phone for that long!
[Galaxy S I9000 General] razzda:
Hehe. I know. I tell ya - my fingers have been ITCHING!

Right folks, here is an image from Juice Plotter, and it concerns 'standby' mode only (oops, as I am a new member I cannot post external links) anyhoo! ;)

h|t|t|x://i52.tinypic.c0m/2r3kndi.png

16:00 to 21:45 is with Wifi on, Background Data on, 3G off, Wifi sleep set to "When screen turns off"

00:45 to 06:30 is all the same except Wifi is off.

There is a big difference in battery drain.

My system:

2.2.1 (JPY) stock via Kies

Hardcore's SpeedMod K12C 500Hz

Lots of apps and a few widgets, but no live wallpaper

My Prime Suspect:

I expect that if I turn off 'Background data' I will get better drainage stats. You will have a graph for that tomorrow sometime.

For those of you have to use 'background data' and / or push or pull methods for notifications, this post is not going to be a great deal of help except to say, that when wifi is enabled (or possibly 3g), something is using the battery on those services or not allowing the phone to sleep as it should.

Hope this helps...
[Galaxy S I9000 General] Stefanauss:
2 questions:

1) So you are leaving the screen off for as long as possible, pratically just checking the battery level and then turning it off immediately?

2) Did you ever run this kind of test but with autosync on? Will you?
[Galaxy S I9000 General] Stefanauss:
I thought it was definitely working for me, too, but i'm not so sure anymore.

The Gallery bug showed up again, even if Auto-Rotation was disabled since boot. More precisely, it was enough to start the gallery just once to cause the increasing clock of sensor usage in Battery History. Just like last time, it can't be stopped. It keeps increasing right now, as i'm writing this.

Although, i have to say, after the first massive drain in the first 20 minutes after starting the gallery (i lost 5% in 20 minutes with the phone just in idle), it kinda stopped on its own. More precisely, i'm not sure if what i did has something to do with stopping the draining earlier than my previous run.

I will follow about this later.
[Galaxy S I9000 General] amwebby:
Did you reset the thumbnail database after running the gallery? I assume you haven't tried 3D Gallery?
[Galaxy S I9000 General] gtluis:
Hi guys!, I've been doing some tests with my phone... I even got to semi-brick it... it's now fine, don't worry.

This were the tests:

1. changed wifi driver using DXJPA

Result: very little improvement (drained 1% every 5 minutes instead of 2)

2. changed modem version installed BUJP5

Result: same drainage as before

3. removed battery icon mod

Result: same drainage

4. installed stock JPU firmware without any mods (no root, no titanium, no battery mod, just stock JPU with stock apps)

Result: battery got same draining of 1% every 2-3 minutes)

This is really really anoying, I've been using my phone to the minimum this last week, and I feel this is wrong, I have the best phone ever and have to "be careful" about usage... that's plain stupid. We should be able to use or phone to the MAX without worrying about battery.

Some people in other thread have seen improved battery downgrading to 2.2. Seems like there is some kind of bug on 2.2.1.

So apparently the solution for draining bug is to go back to JPO, I'll ltry this and let you know guys.
[Galaxy S I9000 General] gtluis:
@Bokbacken

Op, you should really change this thread name to mention the words "battery drain" somewhere.

I've seen several other posts of people opening new thread about battery draining.

I suggest something like "[Battery drain] YABD...... "
[Galaxy S I9000 General] SoSJokerSoS:
You got me wrong. I guess this so called "network notification" does influence the scanning process! Well if you tick it off it will still scann but only if you have wlan properties opened. On the other hand if it is turned on it will scann in background, all the time.

I am not sure if it works that way, but it would make sense.

Thanks for the reminder, did it now :D
[Galaxy S I9000 General] Stefanauss:
I did the database reset, it wasn't helful. I was right in my thinking it is a fix related to FC's, not the sensor bug.

I'm trying to analyze the bug rather than fix it. Next cycle i'm going to try Gallery3D.
[Galaxy S I9000 General] alaimar:
LOL! I was thinking the same thing.
[Galaxy S I9000 General] amwebby:
My experience suggests that, if you delete the thumbnail database and don't open the gallery, battery life is good. Once you've opened the Gallery and rebuilt the database battery drain commences.
[Galaxy S I9000 General] Stefanauss:
Are you referring to previous FWs as well? Gallery wasn't a problem for my whole SGS experience, untile JPX/Y came out.

I really think databases are now ok, or that it is/was an issue specific to some flashes/installation. They are created/recreated in a correct fashion. The very strange issue, which i didn't see in the past 5 month, is the crazy sensor statistics. I would be very surprised if gallery, drain observed after running it, and sensor are not related in some way (which may not be that obvious, i must admit).
[Galaxy S I9000 General] amwebby:
I too did not experience any problems until JPX/Y. My experience there is necessarily limited. Today I switched to the fully-charged Samsung battery, opened the Gallery and only got 9 hours battery life.

I've now inserted the fully-charged third-party, deleted the thumbnail database and battery discharge is running slower; 25% in 3 hours, suggesting 12 hours active use, which is good for the third-party battery.
[Galaxy S I9000 General] Stefanauss:
But the most obvious case is missing: what if you don't delete the databases AND don't open the gallery?

When i did that, i had no draining problems.

Besides that, it looks like you're comparing different batteries. There is no point in running different tests with different batteries, if you're willing to compare the results.

(But i could have understood wrong, and maybe you did all the battery/gallery permutations that are possible)
[Galaxy S I9000 General] amwebby:
Ah but that's where I started. Not deleting databases and not opening the gallery although the gallery had been opened previously.

I know the relative performance of each battery so I believe I can make meaningful comparisions.
[Galaxy S I9000 General] razzda:
@Stefanauss

1) Absolutely correct

2) Will try.

Oddly, I've reached a plateau at T=49 hours, with the drain halted at 38 %. At T=55 hours, it still says 38 %. The only thing I did was turn the volume completely down until it shows "buzzer".

[Galaxy S I9000 General] houlid:
I was following this thread from 2 days (and I've read all the posts), so I tested the issues with wifi on, wifi policy to never, 3g on (but wifi is used), autosync on (gmail push), and auto-rotation off, and all this all the time.

I got the sgs 3 weeks ago with a BUJG2 firmware, flashed it by kies to JP5. Then used only odin to flash it to JPU-->JPX then JPY. I'm using a stock JPY (with stock modem JPY), rooted, then flashed kernel voodo 5.0.3, lagfix enabled (all partitions to ext4).

I have almost a normal battery drain which is 1% (and may be less) per hour when idle.

I tried to use the sgs more heavily:

- browsing the web (display always on) for 20 mins,

- my child playing Shrek Karting for 40 mins,

- then market, using/testing apps,... (display always on) 10 mins

for these almost 1h10mins, I got almost 15% battery drain.

Comparing with other results, I'm very happy with the battery usage on my sgs.

To be (a little) more complete: I use AdFree and DroidWall to block many unwanted network connections. Also the wifi signal is very good.

AND I've done the calibration process as indicated by Stefanauss in a previous post.

I tried to open gallery (1 hour ago), displaying some images, and till now it's still the same battery drain (less than 1% per hour).

If necessary, I can give more informations as requested, or do a special test.

Now I test enabling auto-rotation, opening a max of applications.
[Galaxy S I9000 General] SDeba:
So I would like to share my experiences with modem changing.

I've tested my battery on stock JPY modem then switched to JPP modem and done the same thing.

Personally I think that JPY modem is a lil bit better.

Idle configuration - WIFI OFF, 3G/H ON, BACKGROUND DATA ON, E-MAIL UPDATE OFF, BEAUTIFUL WIDGETS 1h INTERVAL ON

Overnight (idle drain):

JPY - 2-3% - 8h

JPP - 5-6% - 8h

When using WiFi:

JPY - 1% per 5min

JPP - 1% per 3-4min

Heavy Usage - Playing games, watching movies non stop - The time from 100% to 0% is pretty the same, about 6h, don't know if its normal.

Also I was encountering some problems with JPP. My phone had worse signal, sometimes I had lost the signal at all, the 3g/h network stops to work after some hours, then starts again (was in the same place).

So I've decided to move back to JPY modem, but with WiFi driver DXJPA installed. That was my personal observations, and It doesn't mean that everyone should expect the same results.
[Galaxy S I9000 General] baba420:
I can confirm this however I have had the stock JPY modem and JPY wifi firmware.

30 hours of battery life with the following setup:

Doc 6.2 JPY

speedmod 12C with all tweaks, all lagfix disabled

bln enabled

a circle battery

auto-rotation off

brightness to lowest possible, also for the browser

haptic feedback off

launcher pro as default launcher

wifi: off when screen off

data: always on hence when wifi turned off, I still had internet connection

sync: on

a weather widget: update every 1 hour

another weather app: update very 30 minutes

default gmail app on push

listened for about

3 hours

to music with poweramp app.

used the market to update 5 apps

installed 2 new apps

used the browser and a news app (total usage for about 1 hour)

runned 3 times the quadrant benchmark

sent 5 messages

made couple short phone calls (totall less than 5 minutes)

Now I'm really scared to upgrade when a new rom or kernel will be available. 30 hours (and still 2%) is really amazing.
[Galaxy S I9000 General] wobbu:
Fruit Ninja

Just checking if anyone experiencing heavy drain after playing Fruit Ninja? For me, it increases idle/standby battery drain from <1% to 4%, meaning it drains in a day in standby mode.

Some more experiences in this thread
[Galaxy S I9000 General] gulbrillo:
I tested with 3.5G (HSDPA) on (no Wifi) and again it's about 1% per hour. So I will switch back to JPY modem (and newest speedmod kernel) so see if this makes any difference. Will keep JPA firmware though for now.
[Galaxy S I9000 General] chablo12:
i am using sgs with XEU, stock ROM, updated to JPY android 2.2.1 through kies, done a hard reset before upgrade.

Rooted using super one click for installing sgs tools(installed browser which removed 4 tab lock), changed battery icon, removed aldiko, sim tool kit, live wallpapers, unused fonts, social hub.

No lag fix or task manager.

Using apps like. Adobe reader, ag news paper, amazon kindle, kobo, press reader, app organiser, launcher pro, buzz box, twitter, facebook, yahoo messenger and mail (not using mail application), skype, co pilot, picasa tool pro, etc....

Dark wall paper, facebook and twitter 4 hr sync, bright automatic,

Wifi running (always on enabled)

Background data and automatic sync enabled through out, I got more than 40hrs of charge.

Used more than 2hr of internet. Installed few apps, made few phone calls.

Good phone performance, faster and better battery life than jpo with OCLF lag fix.

Display used 70% of power.

Only needs a low power consuming display haha.
[Galaxy S I9000 General] gtluis:
Anybody else having the internet app not closing after having opened any web page? I have to force close app every time I use it, else it just stays there sucking baterry.

I'm now on JPY stock just flashed . Is there a way to fix?
[Galaxy S I9000 General] Stefanauss:
Unfortunately not.

It's a known JPY bug. Or maybe wanted behaviour by Samsung.
[Galaxy S I9000 General] lpy:
For me it isn't sucking battery when closed, it just sits there. It will eventually be removed when the memory is needed. There's nothing to fix from what I can see.
[Galaxy S I9000 General] gtluis:
Contacts has same behaviour.... it's kinda annoying... having apps open once you are not using them, anyways... they are not using any CPU so I guess they are not problematic.

Darkys Rom V7.5

Vodoo Kernel

Vodoo Lagfix enabled

Vodoo Tweaks enabled

From time to time heavily usage.

30min Google Navigation.

20min music

45min games

30min news feeds

15min surfing

~10min flashgames

15min playing around with my phone

I still have 36% left. By the way I use cputuner to save battery. This is an admirable result, but there is still the wifi draining bug. It has to do with the firmware since 2.2 it's getting worse.

Sear in hell Samsung!! ^^

[Galaxy S I9000 General] mkrogh65:
Woobass :) Merry Christmas :)

Well as I see it there are 2 issues here, which might be mixed.

Battery stats and battery calibration.

Im talking about the stats, which is in the batterystats.bin file - obviously.

A readout about the battery usage, which comes from this file.

You / we could discuss how often it is reset / starting over.

Or delete/wipe the file, and then it reports from scratch again.

Battery calibration is about - "just talking this from my "head""

(from forum - and internet search)

Shut down phone -

charge to full.

Startup and discharge with lots of load.

Shutdown again.

Charge to full.

Turn on phone

Now its callibrated. or is it.....

My guess is this will give you 5-15 min. ekstra runtime. (not worth the time)

There is no "wonder" charge.

Nothing will give you a day or 2 more runtime.

But bad programs, kernels, roms or HW will drain your battery faster than it should.

(hopefully not the HW) :)

Have a good one :)

This is also the behaviour of 2.2 and 2.1 as well.
[Galaxy S I9000 General] Stefanauss:
Could you try to upgrade Samsung's Task Manager through Samsung Apps?

I heard reports that this fixes persistent Contacts application, but still leaves Browser there.

No it's not.

Never had that before 2.2.1. I spent several months through eclair and 2.2 builds.
[Galaxy S I9000 General] amwebby:
Upgrading Samsung's task manager makes no difference to Contacts not closing with back key, which it did do in 2.2

Browser does eventually close with back key in 2.2.1 (as it did in 2.2) but, as this often involves multiple back key presses going through previous pages it is not very useful.
[Galaxy S I9000 General] Stefanauss:
Ok, after installing modded gallery through SGS Tools, now Gallery + Sensor battery draining is fixed. I can now see the stats correctly, which means every app is reported using sensor for exactly the time it has been running.

In my previous runs, i also discovered (if we assume that stats are reported correctly) that other applications, like Maps, can keep using the sensor inappropriately. Maybe it could have something to do with Gallery keeping the sensor busy, or something.

This side-issue seems to have disappeared as well, though.

It turned out that the app offered by SGS Tools is not a 3rd party application, but it is an hacked version of the Samsung-Cooliris Gallery.
[Galaxy S I9000 General] amwebby:
So it is as I suspected. I can't install the replacement Gallery via SGS Tools as I have so far been unsuccessful in rooting my phone with one-click root.

Maybe you would like to install hardcore's SpeedMOD? Rooting with it is very simple, and it has many other improvments.

A few days ago I switch wlan on and over night i have lost in 10 hours 2% Battary.

Yesterday before i sleep i surfed in the Internet with Stockbrowser and watch a few Flash-Videos. Then I go to sleep with W-Lan on, and in 5 hours while sleep my Phone lost 28%.
[Galaxy S I9000 General] amwebby:
Thanks. I managed to root it with Oneclick Root v 1.5.5. Have now installed the modded gallery and started monitoring battery use again.
[Galaxy S I9000 General] amwebby:
Installing the modded gallery has had no effect on battery draining from Auto rotation. With Auto rotation on the battery drains at 1% every two minutes. With Auto rotation off if slows to 1% every five minutes.
[Galaxy S I9000 General] SDeba:
Interesting thing. I'll check it out ;)
[Galaxy S I9000 General] gtluis:
Fixed them both!! thank you!

It probably fixes some other bugs, I feel like battery lasts longer now too.
[Galaxy S I9000 General] Stefanauss:
Thanks for reporting back. I'll try this out too. =)

But without rebooting, it seems to make no difference. I'll confirm this after rebooting.

I'll check this out too.

I feel like something's wrong on this side.

Please, can someone who is NOT on JPU/X/Y or any other 2.2.1 but on a 2.2 build, install OsMonitor, sort processes by name, and check what is the average use of the cpu by /system/bin/sensorserver_yamaha on their system when autorotating is enabled? I really don't know/remember, and it would a mess for someone to revert back to 2.2 just to check this little thing.

On my system sensorserver_yamaha is practically always on the list of process which uses more than 0% of cpu, with an average of 4-5%. It would be very important to know for sure if the behaviour has changed since 2.2.1 came out.

A little help would be very appreciated =)

P.S. OsMonitor, not SystemPanel. SystemPanel seems to have a heavier overhead, and does not report on system processes like OsMonitor does out-of-the-box.
[Galaxy S I9000 General] gulbrillo:
The App SGS Info will allow you to show Phone/Battry/Usage Info. (there sould be a key code for this as well)

In German it's Akkuverlauf (Batteryusage?), Nutzung teilweises Aufwachen (Usage in Partial Wake Mode?). Here you will find processes which keep the phone alive. In my case it was Lotus Notes Traveler. Good luck hunting!

SGStools and SystemInfo Widget reports that my battery temp is around 36-40c in most times, when im sleeping in a room with AC its about 30-34c

Is this normal ?
[Galaxy S I9000 General] Stefanauss:
It's too much of an high temp, definitely.
[Galaxy S I9000 General] EarlZ:
How do i lower it, I have system panel running and nothing is really eating up the CPU and is totally idle.. I think ive been getting this temp since they day I got the phone.. avg ambient temp here in the Philippines is around 26c-30 depending on the time of day.

EDIT:

Im guessing its actually CPU temp and not battery temp coz If I play a 3d game, the temp indicator increases as high as 50c and the back top part of the phone where the area for the camera is gets really warm and the battery barely heats up.
