Hi!

Yes I know that, I only want the posters to start thinking a few steps ahead, I don't really care for this "If you only install xxxx:s ROM, all problems are fixed", it's not the kind of posts any of us wish to see here.

Both you and I know for a fact that there are no quick fixes :)
[Galaxy S I9000 General] SKeijmel:
i have no problems on anyfirmware. my phone works like a 7 days or more on each firmware all i use is a stock rom and a app killer i kill all apps everytime i put it into standy. working great for me so far.
[Galaxy S I9000 General] anoneemooz:
True that!

Hm I left my phone untouched for an hour and a half and checked battery history and I'm down to 98%. Apparently my wifi doesn't sleep even if I already set the wifi sleep policy to "Never when plugged" :|
[Galaxy S I9000 General] anoneemooz:
7 days?! lol do you do anything with your phone besides kill apps?
[Galaxy S I9000 General] jackall:
My Bad ... I never touched Gmail sync time, I only set my pop3 sync time, will edit the post with better english ... sorry :)
[Galaxy S I9000 General] bokbacken:
Hi!

Detailed reports as always, you will probably see that the mV change a bit +/- within the % levels as the resolution is much higher in the mV.

I have gotten my phone in the correct setup again after my little mishap, I attached a very tiny wire to the + contact so I can now measure the voltage with my velleman DVM 68, - I take from the simholders metal, it's not that much yet but so far I have:

Time is GMT+1

Time Bat% SGS DVM SGS Diff

19:16 99% 4210 4120 +2,2%

19:24 98% 4188 4110 +1,9%

19:57 97% 4112 4060 +1,3%

Oh, I almost forgot, remember to wait for the "bzz" after shutdown before pulling your battery, it is "worth waiting for":D
[Galaxy S I9000 General] SoSJokerSoS:
I cannot confirm this; i 've never flashed with 100%. Kies allows you to flash below 100%, but what i experienced is the following case:

i flashed several times with kies, and i never got such a draining bug. I also flashed xxjpx and i had NO draining bug.

then i flashed the first time with Odin (Darkys rom V6, which relies on jpx) and i got this draining bug.

I dont know why but this is fact.
[Galaxy S I9000 General] ldjh1985:
No worries mate, does anyone know if you can change the sync time? or do I need to download another email client, any suggestions?
[Galaxy S I9000 General] jonni3:
Hi all, been following this well constucted thread since it started & have been conducting my own little battery test.

Using the set up in my sig along with the xxjpa wifi update/downgrade I have been using juice plotter to monitor the battery usage since a full charge overnight.

I unplugged it at 08:37 as you can see from the attached pic I've been getting around 3.3% drain per hour, this includes 5 minutes of calls, 10 sms msg, a few downloads form dropbox & market over wifi, some game play & listening to music for an hour it's pretty light usage for me (it is xmas day after all).

The xxjpa wifi update/downgrade might not improve battery drastically but it does improve wifi reception over xxjpy (for me it has).

Will be using the phone more over the next few days, so will report back.
[Galaxy S I9000 General] bokbacken:
Update, very interesting in the last measurement:

Time is GMT+1

Time Bat% SGS DVM SGS Diff

19:16 99% 4210 4120 +2,2%

19:24 98% 4188 4110 +1,9%

[Galaxy S I9000 General] salivaman:
And how long was the screen on again?

Everyone seems to give so detailed information while missing out on the most important factor of the battery drain, that is the duration of the display on. Post it as well otherwise it doesn't really help much.

Giving light, medium, heavy etc on usage is too subjective to be considered anything as helpful tbh. My definition of light usage is maybe 3-4 hours of actual screen on time in a 24 hour time frame while someone else may consider that to be heavy usage.

So possible "relatively quiet" usage of 30 mins of screen on and alternatively possible "relatively quiet" usage of 2 hrs of screen on in that 11 hours of standby time is likely to impact the battery life way more than anything else.

I hope you guys know where I'm coming from.
[Galaxy S I9000 General] lpy:
I haven't tried K12C kernel, but I can confirm without doubt that this is a 2.2.1 bug AND NOT a 2.2 bug.

A weak Wifi signal in 2.2 does not cause the phone to use more power and stay awake, but it does with 2.2.1!

Using 2.2.1, once the Wifi signal drops below -70dBm, the phone starts going crazy (power-wise), but with 2.2, the power remains steady and low.

2.2 JP5 (aussie firmware): Fine (4-6mA on standby regardless of signal strength)

2.2.1 JPU: Wifi bug (4-6mA on standby >-70dBm, 25-250mA <-70dBm)

2.2.1 JPY: Wifi bug (4-6mA on standby >-70dBm, 25-250mA <-70dBm)

I'm unsure whether JPY is an official release or not, but if it is, Samsung has introduced a new Wifi bug that wasn't there before.
[Galaxy S I9000 General] zoubidou:
using wifi analyzer (available for free on the market)

i checked the dBm ration of my connected wifi with both driver jpy and jpa

I figured at least one thing:

JPA has a mucher better signal strength (rx) ratio then jpy.

with jpy it barely reached -55dbm most of the time it was around -60dBm

while with jpa it reached -48dbm most of the time it was around -50dBm

don't forget these numbers are algorithmic and therefor the difference represent a lot, especially in power consumption.

so definitively the jpa mod is good for the wifi.

I will change the chanel on my AP to a less disturbed chanel then 6 which it obviously is using, to find out if I can get a better s/n ratio.
[Galaxy S I9000 General] gtluis:
Hello, just to ask you guys, have any of you tried using your phone offline? This bug might not be due to wifi only. I've disabled anything that could be running on phone, gps wifi, rotation, data packets, gmail sync, email sync, hsdpa, etc, etc....

And I started to browse my phone in "offline" mode and surprise, still battery drains like crazy, about 1% every 2 minutes., I'm using minimum brightness and have also disabled voodoo lag fix, I've been using system panel since yesterday, and my top app is "system" I don't know what the hell this is, and I definitely know this doesn't help at all... Another of my to apps was swype, it consumes up to 10-15% cpu, and I don't use it that much... About 15 messages so far...

Could anyone else try using phone without wifi or 3g, and report if there Is still battery drain just by having phone on? (not on stand by).

By the way, I've bern using phone without external SD card and this has no influence in battery drain
[Galaxy S I9000 General] FadeFx:
Hi, just wanted to leave my 2cents on battery drain

Configuration:

Jpy Kies update from jpm/jp6

Docs 6.1 rom

Hardcore k12c

Jpm Modem

After changing the modem from jpy to jp6 i halved my "in use" consumption from ~2min/% to ~5min/% with min brightness so modem does matter for me, but i also doubled my milage by swithcing from surfing xda via steel browser to using xda app with dark theme so i come to the conclusion that the biggest battery hogg actually is the display which is in my opinion way to bright for indoor use when set to lowest value. I even see more drain during writing a post since the background is a bright one in the text field...

Wifi gas for me no difference to hsdpa and in standby i don't loose 1%in 7 hours with beautifull weather k9mail both syncing every hour and background sync always on. I have to check wifi standby which i did not really test since i switched to jpm modem yet.
[Galaxy S I9000 General] mithunjo:
I think so too. I feel battery drain is there on Usage and not only Wifi usage.
[Galaxy S I9000 General] jackall:
@Salivaman from about --> battery Use

Battery = 72 %

Time sine unplugged 12hr 11 mins

Display = 76%

Cell Stdby = 10%

Voice Calls = 8%

Phone idle = 5%

@bokbacken I have also noticed that sometimes the battery voltage seems to "spike" up a little bit, the only thing I can think of is, that perhaps there is a process running which is consuming quite some current from the battery which ends and thus with less drain the battery voltage spikes up a bit.
[Galaxy S I9000 General] FadeFx:
If testing offline power consumption you should also disable all apps that sync in background, they will try to sync and eventually prevent the phone from sleeping and cause higher CPU usage
[Galaxy S I9000 General] zoubidou:
again this is a normal battery behaviour. In fact a battery is like a capacitor (electronic).

if you drain a battery for a while and the stop draining the battery the electrons which are already on there way forward (simply spoken) are already in the output storage, therefore once you require again battery it will give you for a short period of time a voltage and amp spike? how much depends on the battery type, the power you consumed before and a lot of other parameters.
[Galaxy S I9000 General] FadeFx:
By the way, when wifi is on phonograph widget shows me "data off" so 3g/h data is not running in parallel for me...
[Galaxy S I9000 General] roymesi:
Ok, guys,

After reading the last few pages i can say that Hardcore kernel is a positive approach towards better battery life.

Do you agree with me?

I have darky 7 and thinking seriously about installing 12kc...
[Galaxy S I9000 General] zoubidou:
go ahead, it is the right one.
[Galaxy S I9000 General] mkrogh65:
im also on D7, and installed 12c like 3 hours ago.

Seems my batt is better, but to soon to say for sure.

Im wondering if I should go back to Insanity, which has way better batt life ..

Hmmm ...

MKrogh
[Galaxy S I9000 General] gtluis:
Guys, I had an idea... probably we are all using somekind of battery mod (circle battery mod, gauge mod) to be able to see our battery level from status bar.

This might be the cause of battery draining...I "noticed" my battery drain problems once I installed this mod, but... maybe the problems started by installing it. I will disable it, or better yet, reflash a clean install of docs rom again and see if this has any improvements by not using any battery mods.

I will keep you updated about results.
[Galaxy S I9000 General] roymesi:
is Insanity a Rom or a kernel?

Is it fast as Darky?

And what about the battery life?
[Galaxy S I9000 General] mkrogh65:
Its a ROM - Striped completly down.

You can however add all you want after - download and install, from Insanity site.

Have a look at it :)

And I forgot- best batt life I have seen on any Sammy ROMs :)

And really fast too.

[Galaxy S I9000 General] jackall:
To anyone of the guru's out there, could an Android AOSP lock screen prevent the device from properly sleeping ?
[Galaxy S I9000 General] roymesi:
Hmm... sounds tempting. So why did u change to another rom?

And how do I move from Darky 7 to Insanity?
[Galaxy S I9000 General] drakenabarion:
For the wi-fi thing, has everyone got "Network Notification" activated in the WiFi Settings? I haven't seen it mentioned in this thread yet (but maybe I am blind). It would detect instantly whenever a wireless network is in range. So would be constantly searching all the time when activated.
[Galaxy S I9000 General] amwebby:
I have mentioned it before. Turning it off makes no difference as the phone continues to search for wireless networks.
[Galaxy S I9000 General] drakenabarion:
Hehe, of course. It couldnt be that simple :)
[Galaxy S I9000 General] SoSJokerSoS:
i am currently testing it; and what i can say so far is that this could really be our source!!!

My battery status is currently at 24%, and it has already been 24% for 26 mins (since i turned network-search off)

so i am going to wait till 23:00, if it keeps 24%, then this is our bug-source.

[Galaxy S I9000 General] zoubidou:
i have always unchecked this button. but if you look below in the panel, it still scans every 5 seconds, i even have changed the laps of time in between scanning, it still does this every 5 seconds.

This button has no effect on scanning the networks, it only notifys if an open network (not wpa or wep protected) is in the range.
[Galaxy S I9000 General] SoSJokerSoS:
Do you use speedmod kernel?
[Galaxy S I9000 General] suntzu123:
I test. The best thing with 2.2.1 is XXJPY+JP5 modem. But there is a really big problem with battery at normal use. It drain more power at normal use. I got like 2 times less battery time at using.
[Galaxy S I9000 General] zoubidou:
yes 250 K12C

with darky's 7.0
[Galaxy S I9000 General] SoSJokerSoS:
Could you define "normal" use?

Do you mean with wifi off, or what do you mean, because if i turn wifi off it doesn't drains battery at a normal level.
[Galaxy S I9000 General] SoSJokerSoS:
I dont know why, but it works!!!

I will fully charge my phone and will deliver a proper report tomorrow, but it seems that this was the problem (at least for me).

btw:

I use speedmod + speedmod lagfixes and tweaks

I9000XXJPY (even XXJPY modem file)

[Galaxy S I9000 General] SoSJokerSoS:
well did you just discovered the gallery bug?

Did i get that right that you use "stock" jpy?
[Galaxy S I9000 General] Stefanauss:
If you mean "re-discovered", well, i don't know. I read a lot but never find confimation that the bug was still present (i asked previously in this very thread, no answer), actually someone in other threads said it was fixed.

The thing is, now i know for sure.

Stock, no custom kernel with patches, no skinned/light/customized ROMs like Darky, no Voodoo, no Lagfix, just root.
[Galaxy S I9000 General] zoubidou:
Thanks Stefanauss for this excellent post and analizis.

in a former post i also figured the sensor_yamaha had something to do with it. it did not use the gallery, but i switched several time my phone from portrait to landscape.

And also you can find posts in darky's or doc's threads, stating that the rotation is not working anymore.

I have checked this, and sometimes it does not rotate when on the home screen.

Thats where the different launchers come into pace. I never had this problem with launcher pro. I had this problem with darky's gingerbread launcher, nor the home screen nor the application screen rotates. It is possibly not planned for, but I would be surprised that google implements something which does not rotate.

I don't know about the other launcher because i am not using those, but somebody could check.

With applications, it always rotates.
[Galaxy S I9000 General] ReiKo90:
Ok people,

I just can't stand around and do nothing while so many are contributing. Especially you bokbacken, you are ****ing beast and you have some sexy answers to all the problems. Concrete and without further ado:

I'm using Samsung Galaxy S (International edition) with Darky's 7.0 MOD

I flashed Voodoo Advance 1.3 Kernel beacuse Darky's ROM had issues with camera (when using applications that use camera like Barcode Scanner and Google Goggles).

Before that I had vanilla stock Android 2.1

Earlier this morning I tried simple stuff: Turn on WI-FI while my battery was around 80% and leave phone for a half an hour without doing anything.

After 32 minutes I see my battery drained 5-6%.

Keep in mind I'm using Anroid Live Wallpaper but there were no applications runing while phone was staying put.

Firmware is 2.2.1

Kernel 2.6.32.9

I9000XXJPY

I hope this helps. Keep up the good work.
[Galaxy S I9000 General] suua:
Hey guys :)

I am running darkys v7 rom. And i flashed speedmod kernel K12, the battery seems to be better but not so huge difrenc.

Hopning for a fix soon.

And can some on tell me where to get the wifi fix, couse i think is the wifi that is killing the battery.
[Galaxy S I9000 General] bokbacken:
Way out of topic and advertising a ROM purely on hearsay, there are no evidence what so ever that insanity's rom should be any better, so keep this out of this forum.

@roymesi, visit the different rom's thread and read about 50 pages, everybode say the rom the are using is the best on everything, find out for yourself by trying a few.

@mkrogh65 it's ok to like the rom your on, I love Doc's rom, but I will not say that it is the best rom around (when I'm here in my own thread anyway;)) but it's ok, you only answered a question.

@all other contributors, thanks for ignoring these posts!!

You are giving me a lot to analyze, would be grate to have Abby (ncis) doing some work here!

@Ipy good reports continue to arrive from you, btw have you hooked up an external currentmeter, or have you found an app that works in SGS 2.2.1??

@Stefanauss seen your post on other threads as well and the are very good, but this report you have given us here is SUPER, I wish to extend my very sincere thanks for this one.

I will try and find the time to go trough the posts in more detail tomorrow, see you soon.

[Galaxy S I9000 General] drakenabarion:
It would be nice it things were that simple, but battery drainage is linked to battery usage. This may be a large factor but, I use a Live Desktop, and that is going to have a big affect on battery performance. As always, it is personal usage that affects battery life in the end, and the best that can happen is a combination of solutions. But its up to the end user which solution they use and which solution they ignore.

Still, I have had improvement since I disabled Network search. I disconnected power at about 5-6 pm and I am at 45% at 2:30 am. This might not seem like much, but it is indeed a big extension of the usual battery life.

Again other factor will play into this. While my phone was at 100% battery, I deleted the battery history, so, it has yet to calibrate.

p.s. thank you firefox spell-checker. I cant spell today but that doesn't show in the above post ;)
[Galaxy S I9000 General] suua:
Thanx mate, can u tell me how to install it. Do i need to disable anything begor i install it. And with odin or CWM Recovery? Thanks again.

about wifi bug:

Darky 7.0

JPY modem

how to reproduce? goto wifi settings, wifi on, 'scanning' appears every 5 secs or so.

i dont know if it is specifically enabled for this screen to provide current list to user or device behaves like that always.

if wifi is on, no matter if connected or not every 5 secs scanning for new network occurs. no matter if network connected or not, no matter if notifications enabled. (maybe its occuring even with wifi: off? unlikely but well.... Its Samsung's wonder device.)

[Galaxy S I9000 General] zmafreak:
I'm using the same setup (k12c) but the drain is worse. I think its the JPY issue.. I might shift back to Darky's v6 or official JPX
[Galaxy S I9000 General] mithunjo:
Clicked on ur link, using dolphin mini, after 5 seconds of it opening the screen and trying to scroll, the screen turned off and hung. Had to do a battery remove to start the phone again. Wonder why that happened..
[Galaxy S I9000 General] mithunjo:
Coming to the topic. Did my bit of testing yesterday. With screen off. With everything OFF including wifi, lost 14% in 7 hours. That's fine I think.

Woke up, turned on wifi and opened only the xda app, browsing for half an hour, lost 1% every 5 mins.

So are the above drains normal?
[Galaxy S I9000 General] zoubidou:
look at the posts just one page before!!!
[Galaxy S I9000 General] zoubidou:
first of all there is no 2000mAH battery. second i don't belive that this fixes the problem. if the battery is mis-aligned it wan't be correct with a bigger battery. And if the SGS want to shut off, it will do it, no matter how much you have left in the battery.

Besides that there is a thread for accessories which is more suitable for this kind of ad.
[Galaxy S I9000 General] drakenabarion:
Oh the battery I ordered has a higher duration. Still, doesn't mean I want to have to charge every single day. I got a double duration batter with the hopes of not having to charge every single day. (Just because you CAN have everything using up all the power doesn't mean that you HAVE to have everything draining the power <grin>).
[Galaxy S I9000 General] zmafreak:
Did that update work for you ?

I'm not promoting an ad or something.. It was a random find :(

Wasnt the way it was supposed to be used ? :mad:
[Galaxy S I9000 General] lpy:
External multimeter. An app would be handy, but I'm not sure if it's possible. Very easy to do, if you have a spare battery you're willing to sacrifice by soldering wires onto it, and then soldering wires to the phone's battery pins (with extreme caution!). It takes out all the guess work of what's going on and allows you to see in realtime how the battery is being used.
[Galaxy S I9000 General] ldjh1985:
Morning all,

A few interesting finds...

Last night I decide to fully charge the SGS again until the phone reported it was 100% charged and that I was asked to remove the power,when i removed the power my phone instantly reported charge of 97% although the phone & Juiceplotter reported it being fully charged :confused:

I woke up this morning some 8 hours after I started my own mini test and I had lost 4%, this was with the following setup:

- SetCPU - Conservative

- WIFI On

- Autorotate On

- Brightness Lowest possible

- Auto Sync off

- 3G off

- Bluetooth off

- GPS off

- Packet Data off

- Data Roaming off

- USB debugging disabled

I really think i've isolated my issue to be with the auto sync. Tonight ill fully charge, turn auto sync on aslong with the WIFI and see what results I see in the morning.
[Galaxy S I9000 General] amwebby:
Having read Stefahauss' posting I too disabled Auto rotation. Just as he experienced, battery draining returned to normal levels. I have two batteries, a Samsung one and a third-party one and an external charger that uses MPPTT to maximize the charge. The third-party normally gives me 8-15 hours of use and the Samsung 12-20. With the battery drain I was getting 5 and 8 respectively. I just got 15 hours overnight with the third-party battery and am about to test the Samsung.

It's a workaround but it seems to work.
[Galaxy S I9000 General] zoubidou:
you should have recalibrated the batterie otherwise what you did does not change anything to any former batterie pb.

also, you can very well have autosync to on, and wifi to off, since it will then sync through the 3G. It is a known fact that wifi especially in jpy drains a loot of batterie. thats why there is a patch available in post 1
[Galaxy S I9000 General] ldjh1985:
The fix is already applied in Darkys latest Rom I believe.
[Galaxy S I9000 General] zoubidou:
not as i know, but i am sure he has a link there for the patch and how to apply.
