just a quicky, because i am a little bit tired of this. to much data for nearly nothing.

the only thing i know is, that possibly the gallery is involved somehow especially to the rotation sensor from yamaha, and the screen roatation does work or not on the homescreen, depending on the launcher you are using.

Wifi is also involved but much less if setup correctly.

The other things are very personal and what you have installed and are using.

Ok.

My phone was on battery for more than 2 days (48hours) and still had 14% left over.

I am using darky's 7.5 and speedmode kernel with all ext4 lagfix K12C.

I have 2 exchange email accounts (pushed) and 1 gmail account, and i use the galaxy tab email client.

I don't play this super duper game called angry birds, but i play appeak poker, which is as much battery draining (and nerve wrecking).

I have set up my wifi to android default in spare parts.

And once the screen is off in settings.

which is a bit funny, because each time i use my phone it takes a second to reconnect to wifi, but at least it shows that wifi is off during sleeping time.

I did not turn data off, nor 3G, or Edge.

i have everything synced through push.

And my phone just suggested that I should connected the charger, it was disconnected since yesterday 7 am, ie i nearly got it through 48h, in fact I still have 15% left over, and i am even using animations.
[Galaxy S I9000 General] amwebby:
Further to my last post I did find that downgrading to the 3D Gallery does allow you to keep Auto rotation on without battery drain. The only downside to this, which I've just discovered, is that the 3D Gallery doesn't support Lock screen wallpaper.

I've also discovered that if you DON'T upgrade the program monitor to 1.5 but keep it at 1.12 then Contacts DOES close with the back key.
[Galaxy S I9000 General] EarlZ:
Also if our batter is rated at 3.2v why does it die down as early as 3.5v from a 4.2v charge?
[Galaxy S I9000 General] Stefanauss:
Do you mean sensorserver_yamaha wasn't in the list at all, or that it was using 0% cpu even with autorotation ON? This is very important, i hope you could clarify =) (You would better find this out if you sort processes in OSMonitor by load)

Beside that, do you remember which processes? Of course occasionally any process would use some cpu, but which of them were using cpu more often?
[Galaxy S I9000 General] EarlZ:
Also w/c firmware version disbled the trickle charging on SGS, JPY ?

EDIT:

Id like to add that just a couple of mins ago my phone was at 2% and I locked the screen, went to my PC and did some stuff. I didnt notice it vibrated but the phone when off, I powered it on again and still got the 2% display.. after like 2mins it powered off with the regular shutdown screen and it didnt wanna power on back again, So i connected it to the charger and charged it for 1min. Booted into recovery mode and deleted the battery stat and wanted to wait till it will shut off.. waited for 10mins didnt shut off.. I performed ( just for the fun of it ) a full nandriod back up (its around 950MB) and my phone was able to finish the back up w/o shutting down and how its still sitting on the recovery menu for 10mins..

So this means my battery meter is very off ?
[Galaxy S I9000 General] Stefanauss:
Something strange happened to me this morning, and i think it's related to this.

Yesterday night at 22:30 i was at 27%, i went to sleep, this morning at 6:30 the phone was off. So i put it in charge, but i saw the green bar was not at the first step, but at its 2nd or 3rd step. So i plug out the charger, boot the phone and there were 28% left!

After a sync it showed there were a lot of updates in the market, i let the phone download them all. In the meantime i checked the battery voltage in real time, with 1s refresh (no spare parts, but with a phone-code) and they were down to 3.2-3.3 V! Never seen such low voltages.

Shortly after installing all the updates (the mark went down to 24%) battery died.

I did the same, charger on, unplugged, booted again, this time when boot was almost completed the phone did the shutdown sound. The interesting part was the it kept booting. I was able to reach the home, widgets were in loading. Suddenly it did the confirmation buzz and eventually, it went off. It was like a normal shutdown, except the phone was ON all the time during the shutdown procedure!

This time there was no way to boot again, battery seemed really dead. So i plug the charger back in, booted, and the phone was actually showing 0% even with the charger plugged for all the boot stage. It kept itself at 0% for a while, then 1% and so on.

Now it's at 96% (i'm charging while on this time, the first time after the recalibration) at the voltage already reached the max 4.240 mV, it's just keeping it costant.

Why you're saying battery "is rated at 3.2v"? Wasn't 3.5 V the value reported on the back on the battery?
[Galaxy S I9000 General] oliver005:
Well, yesterday I charged my phone to full and 30min after I went to another city (167km away). Was using GPS all the time with 3g on, battery died in 3h 50 min. Minimum brightness, no autosync, no data background, no wi-fi, no bt, no auto-rotate. After 50% I even enabled Screen filter and was using screen at 40% of a minimum lvl. It died after 3h 50m anyway. So If you enable all the things, like full brightness, autosync, background data etc etc etc, it will die much faster than that.

Btw phone is working about 52hours on normal use (with total time screen on around 5-6 hours)
[Galaxy S I9000 General] gabrielcorneanu:
I don't have a very big drain problem(especially in standby), but not satisfied with battery life either...

I was trying to monitor cpu usage and got some questions.

With "usage timeline" I see one process "security storage" using lot of cpu, 5-15 %. Does anyone know what it is?

With OSMonitor I don't see it at all! But I see the sensor process @~4%.

Can anyone clarify?

On wifi problem, I have just observed that it uses more power than cell data. Is it normal? Plus that cell coverage is quite poor at home while wlan has ~-45 db signal (very good).

Thanks,

Gabriel
[Galaxy S I9000 General] MatrixASmith:
in my case, the culprit seems to be email.apk, combined with hsdpa traffic data. The effect of using the modem for data traffic amplifies battery drain (over battery drain caused while on wifi)

Removing email accounts and just using gmail keeps battery strain under control,even if not optimal.

I hope this can help
[Galaxy S I9000 General] EarlZ:
my bad its about 3.7
[Galaxy S I9000 General] bokbacken:
SGS Email 2.2.1

Did a little test with my phone since yesterday, as the email application have to be in the phone if you want to use camera dependant apps, so this is what I did:

Reinstalled the phone, setup the google account with sync on (contacts and calendar), setup the exchange account with push for peak hours and manual otherwise after 8 hours with manual on I changed that to push also to stop the drain!

(Click to view larger image)

Now I have passed 29h with the phone on battery level at 56%, and this morning I've been using it a little, sent a few SMS and recived a few (total 15) copied the systemrecord.db from systempanel.

But the important thing here is that the email application is using more juice when sync is set to manual (I didnt do any email checks in that time), but for me it is ok to use it in push mode!
[Galaxy S I9000 General] bokbacken:
"To much data...."

I fully understand your point of view, browsing this thread there is a lot of information and a lot of this is data that many of us are not affected by, but I said in the start that we must have patience in this, battery data and facts is not something we will get in a couple of hours or even a few days.

You have been a very good contributor to this thread, and I thank you very much for that and I hear you in this also!

How old is this thread now? Pretty exactly a week now.

Have we learned anything in this week? I must say that I have certainly learned a lot.

Call out to posters/readers!!

But a week is a long time in the android world so probably we need to do some summarization and show some tips & tricks and do's and don'ts

If you can think about some specific facts for these categories please PM me with this and I will put together something that we can spread to the community.
[Galaxy S I9000 General] mrhoggorm:
Im just throwing this in... i had big battery drain problems, im on darkys 7.6 btw. What happened, is that i flashed the CSC_I9000XEEJP4.tar.md5 using odin, and the battery drain seems to have disappeared, i also set my wifi to static ip. Now everything is back to normal (if not better), my phone has used 12% in 9 hours :D :D
[Galaxy S I9000 General] TheYar:
I just stumbled across this thread and thought I'd link my battery drain thread that I've kept going for a while now. I know there are a bunch of battery drain threads out there, probably a lot of duplicate info, but let me know if anything helps.
[Galaxy S I9000 General] bokbacken:
You link to mine and I'll put a link to yours, we should help eachother identifying the problems and isolate them.

Hope you found some useful information here.
[Galaxy S I9000 General] nks14:
i was on darky 7.5 (jpy) with jpe modem and speedmod kernel (latest). i had the wifi fix. at 10pm i took the charger out; phone was 100%. played robo defense for about 40minutes then i went to bed. in the morning (10am) when i woke up, phone was off.

my settings are:

wifi - off (never use wifi)

hspa/3g - on (auto sync)

email - 1 gmail account, 2 imap accounts (default sgs email)

widget - simi clock with weather
[Galaxy S I9000 General] bokbacken:
Remove your imap account's and try again, even with manual update SGS email app is using a lot of battery, it is only good with push (exchange)

Please do try this and report back then we have one more confirmation on this.

Edit: I can add that this was the reason why I started this thread in the first place!
[Galaxy S I9000 General] vandallpl:
charge time

Hi all

i have fllshed my sgs yesterday from stock 2.2 to darkys 7.6 (wipe) and i have noticed battery drain as many others. But what i have noticed is that charge time increased a lot, can anyone confirm that please ?
[Galaxy S I9000 General] bokbacken:
There is a connection, if your phone is on and you expireance a massive drain, then it will take a longer time to charge also, an example (never mind the numbers)

Charger output 500mA

1500mA battery is almost empty

case 1:

phone off draws nothing

chargetime 3 hours

case 2:

phone on with heavy drain, draws 250mA

chargetime 6 hours

When my phone was at it's worst (little more than a week ago) I used it as GPS in the car, I was on 34% at start, 1 hour later I was still on 34% there where no charging at all, I was only able to maintain the battery at present level.

Check post #3 and try hardcore's kernel and wifi "fix", it works in Darkyy's ROM it has helped a lot of people, and please report back.
[Galaxy S I9000 General] vandallpl:
I have sorted my battery issues by calibrating battery :) (after disconnecting phone i got 100% for about 2hrs).

Now, after 12 hrs (few calls, text messages,3G on, 2hrs of 3D gaming and 20 mins on GPS) im on 52% :cool:

What suprised me is that charging time on JP5 from empty was around 6hrs

now is almost 12 :eek:
[Galaxy S I9000 General] EarlZ:
How did you exactly calibrate your battery ?

Whats bugging me right now is the instant drop from 100% when I disconnect the charger, started to happen yesterday.. if its a JPY issue it should be have there on the first day I've used it!
[Galaxy S I9000 General] vandallpl:
i drained battery to 0, then charged to maximum using wall socket charger, and disconnected phone 3hrs AFTER battery was fully charged.
[Galaxy S I9000 General] EarlZ:
Charged it while the phone is off right ?
[Galaxy S I9000 General] vandallpl:
nope, phone was on, but only basic stuff , no 3g wifi or other things

thing is that i flashed phone when battery was around 80%, after new rom kicked in (5 mins) it reported 53%

so i figured out that recalibration will sort out everything, worktime seems fine but charge time weeeell...

IMHO problem lays in 3 things :

1. calibration

2. battery driver

3. wifi is using much more power on JPY
[Galaxy S I9000 General] EarlZ:
Are you not getting the immediate power drop from 100% after you unplug the charger? coz mine started to act that way yesterday.. and my idle drain is 1% per hr.

Only in 2G and no WIFI.
[Galaxy S I9000 General] bokbacken:
For you it seems to be these 3 things (so far), #3 should be a bit better with hardcore's or trasig's kernel that still is linked from post #3
[Galaxy S I9000 General] vandallpl:
Well, #1 sorted my problem but you missing the point (no offence) i have read entire discussion and no one noticed that charge time increased aswell as power drain. That means that battery control software is the problem, not other stuff.

There is already package to downgrade modem to JPA (post no 3)which will fix power issues and GPS precision.

I think that someone should take a closer look at battery driver.

I left my phone charging 3 hrs after i got message that it is full, then battery was at 100% for over 2hrs !
[Galaxy S I9000 General] vandallpl:
No, it took over 2 hrs to go from 100% to 99% (1 call, 1 sms and screen at full brightness)
[Galaxy S I9000 General] EarlZ:
and your using JPY right ? 2hrs of screen time and only 1% drop ?

Whats funky on my end is that i power off my phone, charge to 100%, do 2 bump charges and boot to recovery mode and delete the battery stats, power off the phone again and let it charge to full when it hits 100% again i boot the phone and my guage tells me its 97% on boot.. i wait for it to charge to 100% after several mins, it hits 100% then i disconnect the charger i get anything from 99% ~97% w/c never happened up until yesterday.
[Galaxy S I9000 General] vandallpl:
hmmm what i did exactly, step by step:

1. abuse battery (mp3 player, flashlight, max brightness, gps in building, 3g , wifi , etc)

2. charge phone to 100%

3. leave it charging for 3 more hours

4. reset battery logs when still charging

5. disconnect from charger after reboot

i simply think that battery driver is at fault and it is reporting full battery when it is far from full... (it is only my opinion) i would love to test batt driver from JP5 or JPA
[Galaxy S I9000 General] EarlZ:
Is there a way to extract and use the battery driver from another firmware version ?
[Galaxy S I9000 General] vandallpl:
Its linux, everything is possible. I cant do that because i have android device for 3 days :p (working heavilly on my own kernel fixes thou) AND im going on holidays in three days.

there is one more thing u can try, but i dont want to post it, its kinda crazy.. PM me if u want to know
[Galaxy S I9000 General] EarlZ:
Going back to a JPM firmware does not drop the battery charge level from unplugging, so its definitely some sort of driver mess up.
[Galaxy S I9000 General] xan:
There seems to be a problem with Yamaha sensor drivers...

It bugged for me one time, was stuck using like 15% of the CPU, no matter if auto rotation on/off...
[Galaxy S I9000 General] vandallpl:
what sensor ?
[Galaxy S I9000 General] EarlZ:
Is there like a gallery version thats fast and does not have the sensor bug ?
[Galaxy S I9000 General] xan:
Yamaha - accelerometer, compass...
[Galaxy S I9000 General] vandallpl:
jus switch off auto rotation and see if it helps
[Galaxy S I9000 General] xan:
Tried that, tried killing it, tried deleting files(dont recommend)... Just a simple restart helped, but knowledge that it can just 'hang' randomly and eat 15% of cpu all the time no matter what...

Priceless...
[Galaxy S I9000 General] vandallpl:
im not even near this problem, please understand... im pointing out that charge time is increased on JPY

If you need help, PM me, dont use this thread to one person problem
[Galaxy S I9000 General] xan:
Must...resist...
[Galaxy S I9000 General] Seifer1975:
Have you guys considered the mediascan process? My own experience. I downloaded the "rescan media root" app and disabled media scan. The first 2 nights without it running, my phone registered 3-4% drain over 8 hours of idle. Then I re-enabled the media scan and with no other changes, phone registered 12% drain over the same 8 hours of idle.
[Galaxy S I9000 General] lpy:
Just a note with 2.2.1, the drop is quite aggressive from 100-90%, even in deep sleep. After that it's normal.

I stopped using my phone at 3am and it was at 75%. I checked again at 12pm and it was still 75%. This is no longer the case at 100% as it was with 2.2. No big deal really.

Running JPY 2.2.1 with SpeedMod, 3G disabled overnight and WiFi set to switch off on screen off.
[Galaxy S I9000 General] Stefanauss:
This has been the case for me since i got the phone back in August.

No matter what firmware, recalibration or not, keeping it full of apps, leaving it empty, external sd card or not, lagfix or not, whatever.

100-90 is the fastest drain.
[Galaxy S I9000 General] bokbacken:
ROFL :D

Remeber the Borg: "Resistance is futile"

How often does this occure?

How much UV do you use in lower freq?

Have you tried a different kernel?

I never had this problem (that I know anyway), and I have always used autorotation and also use sensors together with GPS.

(Maybe this is "one person problem" :rolleyes: :D , sorry couldn't resist -> you're a better person than me...)
[Galaxy S I9000 General] bokbacken:
"dont use this thread to one person problem" this makes me :mad:

If you had taken the time to read a bit more you would have understood that this is a problem that many people are affected by.

-----------

(Increased charge time <> battery drain) -> true

Refering to your logic, you should not use this thread

Most of the chef's and kernel makers have answered this one but you don't see the connection:

2.2.1 has a different way of charging the batteries to prolong the life of the lithium cells, they will not charge to 100% the details about this is not known to me, if you have 100% battery shown for more than 1 hour while using your device with full brightness, then you are either lying or your "battery calibration" is way off.

In post number 2 check the links to the expert witnesses

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

BTW, I guess you missed a "not" in your first post:

"Hi all

i have fllshed my sgs yesterday from stock 2.2 to darkys 7.6 (wipe) and i have not noticed battery drain as many others. But what i have noticed is that charge time increased a lot, can anyone confirm that please ?"

---------

the yamaha sensor is also mentioned a few times in this thread so please use the "search this thread" next time.

----------

And finally:

Don't insult people like you did in the quoted comment that made me :mad:

xan is a very competent contributor to this thread and the whole community, you may even use his splendid Voltagecontrol when you change to trasig's kernel to do some tuning on your Galaxy someday

a tip for you: xan, Posts: 787 > vandallpl, Posts: 11

check that info and think about it before pointing out things that been mentioned more than 1 time in this thread

Re-read this now:

no matter if auto rotation on/off

search this thread, sensor 30 hits, yamaha 10 hits (not counting the quoted)

..... I think he already tried that!!!

Very interesting info in a Battery Drain thread, don't you think?
[Galaxy S I9000 General] nks14:
well, the thing is that the server supports only pop3 and imap, so i cant setup an exchange account; so, my sollution was to revert to 2.2 JP9 and everything works fine now;
[Galaxy S I9000 General] vandallpl:
How many people are affected by freezing autorotation app?

-----------

You are right, im sorry...

Xan im really sorry if i ofended you, it was not meant :(

Small update, phone is now 24hrs without charging, battery 49% (auto rotation on, 3G off, wifi off)
[Galaxy S I9000 General] bokbacken:
We're good now :D, no hard feelings I said what I needed to say.

I myself have quite good battery life nowdays took me 40 hours untill phone shut down itself (3% in my case) and then I did force it with some data traffic and angry birds. 3G is always on in my case, at the moment I have also activated wifi to see how much extra drain this causes me doesn't seem to be a major problem for me, but I will go the full cycle with it on to be sure. Looking in systempanel (Forensic tool, see post #1) it took just over 3 hours charging from 3% to 100% with phone turn on, so I'd say that looks correct.

Regarding calibration of the battery I haven't seen any true facts in this, only a lot of suggestions, the one I think could be correct is linked in Darkyy's first post (right after the link to this thread ;)): try his suggestion

http://xdaforums.com/showpost.php?p=10092321&postcount=11053

And please keep us informed, this is in fact interesting also :)

Edit, forgot to answer your question:

I try to keep up with a few threads, DocRambone, Darkyy, hardcore and trasig these are the ones I put my focus on, and sensor bugs keep popping up in there all the time, but I'm not able to tell you how many are affected, only that they are many.

It's not that easy to put together a thread like this if it should be able to help anyone, it's close to a full time job to keep up and gather information, but you learn a lot in the process. This thread is only 8 days old but close to 500 posts.
[Galaxy S I9000 General] vandallpl:
phone has 20% battery left (from 44%) after approx. 1 hour on the road with gps and 3G screen brightness minimal.

Thanks and happy new year !

Testing

Hello all,

I am just one of those silend readers here :)

Did some tests the last 2 weeks.

JPA release 2.2 SDK8 , kernel VooDoo 5 stable RC1.

Apps:

SuperPower (CPU scaling, WiFi and 3G of when not used, Night mode)

ScreenFilter (59% when engaged)

SystemPanel for monitoring

I am on 48h right now, started with 36h. Yesterday I noticed that the battery drops very fast when on-road using 3G and H data traffic. I just gets very hot and had a drop from 90 to 40%! After this it climed back to 75%. It looks that something is draining the hell out of a battery during data usage whith changing data-coverage.

Normally (As far as I know) a phone changes it sencibility in sending and reception of data, within its limits. I suspect that when coverage is poor it boosts its power and draining the battery too fast.

Could this be?

I think I will end up with 72h (3 day's)
[Galaxy S I9000 General] ingineru:
Please note that almost every big email provider can be set-up with push ( except Yahoo ).

- Microsoft exchange

- Microsoft Hotmail or Live : select exchange activesync, put username and pass and set m.hotmail.com as server name

- Gmail : select exchange activesync, put username and pass and set m.google.com as server name

I am on jpx, i have 4 email accounts configured ( 2 push, 2 manual ), email app is not consuming battery if data connections ( 3g or wifi ) are off and yes, it does consume if it is set to check at regular intervals and data is on.
[Galaxy S I9000 General] ingineru:
Same for me, but this is happening only lately since i switched to jpx
[Galaxy S I9000 General] EarlZ:
JPU is 2.2.1 right?

I never got that battery wont charge to 100% with JPU,JPX and JPY up until 2 days ago. My 100% status would stay about 30mins and drop regularly up until 2 days where I disconnect my phone and get 97-98% then 1% drop per hour, this is wifi/bt/3g off.
[Galaxy S I9000 General] bokbacken:
Hi EarlZ!

The charging has changed in 2.2.1 almost everybody has this behaviour (or will get it) in my post #2 there are 2 expert witnesses with interesting info.

But I must admit, I don't have any real facts about this yet.

Also go through post #4 to see if you might be affected by any of these usual drainers.
