[Galaxy S I9000 General] Neried:
This is the only downside I have experienced with ginger, let alone 2.3.4. I am glad that I am not the only one with this issue, as asking in the romkitchen chat channel or any other support group didn't give me an answer.

This bugs the hell out of me, I charge my phone overnight to wake up to a full battery, but since getting on the GB bandwagon not long after it came out, I have experienced this stupid bug nearly daily. Every blue moon I will wake up and it'll be 100% after I disconnect, I usually have a good day then.

I have experienced from 88% after disconnecting charger, to 36% and once it powered off and I punched a goat (I didn't, but you feel my anger).

I did read in the cyanogen mod bug tracker this bug was reported and supposedly fixed, but good luck finding that information again :( I don't use cyanogen mod, but a quick google of this bug once upon a time yielded that result.

I would really love to see this bug fixed; if it was done on purpose, a big middle finger to you Samsung. It does not make sense, I would prefer to reduce the life of my battery by leavin the damn thing on charge for longer than I am supposed to, then wake up to 36% remaining. It is quite inconvenient.

Hope we have a resolve soon.

<Rant> So I put my phone back on charge this morning after waking up to it @ 100%, removing charger and down to 85%. Went to get it off charge, said it was @ 100% again, took it off... 82%. Bite my arse phone ARHH </RANT>
[Galaxy S I9000 General] Martux64:
It's a know issue :o
[Galaxy S I9000 General] Wastl0r:
I reached a new low yesterday.

When I came home my battery showed 80%, so I plugged it to my PC. It stayed there for about 4 hours without touching it.

Then I unplugged it and BAM, battery went straight down to 37%...

It's really annoying since this happens almost every day...

Does anyone know if Samsung is working on this?

I hope they fix that soon!

[Galaxy S I9000 General] Peacemanibk:
One thing you can do to minimize this effect is to disable as much as you can before putting it onto the charger (+flightmode) ... or if you dont have the need of using the alarm switch the phone off during the night.

But i really hope they fix it soon... but i am still wondering why it seems some people dont have this bug??
[Galaxy S I9000 General] goughymachine:
Me too! I guess not everyone connects their phones overnight? I had it every time, on every gb rom.
[Galaxy S I9000 General] $omator:
just disable wifi for night
[Galaxy S I9000 General] pwhooftman:
Jusy a suggestion, have any of you rebooted into recovery while the phpne was still on the charger and deleted battery stats? Just guessing, maybe thats what kept the bug away for me....
[Galaxy S I9000 General] Peacemanibk:
Well i have done this twice since my last flash of JVP and i still have the bug. Also i doubt that recalibration can help anyways...
[Galaxy S I9000 General] apolas:
Well, I've read several times on this thread that this bug is only on Gingerbread. But guess what? I have the same issue on Froyo JPY. I tried GB rom some time ago, but I decided to go back to JPY because of android system bug in GB, which drains the battery.

Past few days I'm trying to find out why my battery drains so fast and today morning I've found that my battery falls down from 100% to 91% instantly after disconnecting the charger, which was plugged all night.

Before I've flashed GB I could use my phone for 2 days. Now I have to charge it every night, because in the evening my battery level is at 30 %. I've tried to root and delete battery stats, recalibrate, but it is still the same. According to system, 80+ % of battery usage is display, but I'm not using the phone more than before. Definitely my battery or something in the system is screwed up. I wish I will find it out. I'm worried to buy a new battery if there is something wrong within the system.
[Galaxy S I9000 General] JKM2247:
This bug is real. In my case, after overnight charging, on disconnecting from charger, the charge level drops 100% to 90% instantly.

I love everything else of 2.3.4;more so the speed and lack of any lag, so I have had to look for a solution to this bug. Last night I charged the phone fully and disconnected charger before sleeping. When I woke up this morning charge level was at 94%. So as I prepared to get out to the world, i.e shower, breakfast and stuff, I charged the phone so that as I get out of the house I have had 100% charge and ready for the world.

So it's no longer an issue to me until Samsung gets the grace to fix the bug
[Galaxy S I9000 General] $omator:
probably your screen is not going to sleep mode (not turning off but displaying black color)

why is thaat it is hard to tell wo bugreport
[Galaxy S I9000 General] apolas:
Any suggestions how can I test this issue?

EDIT:

I'm checking battery status with battery monitor widget and it seems that while screen is off, it drains about 1% per hour. I will try to let the screen on for some time to see how much of battery it will consume.

- Result is 10% in 30 minutes
[Galaxy S I9000 General] $omator:
well display is thebattery killer, no dubt about that maybe stats got more accurate or you just used phone more
[Galaxy S I9000 General] pinoypower:
This is what I've been doing - recharging until it shows 100% after pulling the plug. But this does not work all the time as most mornings I would wake up with 30% charge left. There's just not enough time to fully charge it until I have to leave for work, so I always carry a spare battery charged from an ac charger. The custom GB rom I have on my phone is just too good for me to go back to froyo.
[Galaxy S I9000 General] Prankey:
I have finally replicated 100% to 0% phenomenon on a completely idle phone (only wifi was on.. no tether or 3G or screen).

I had the pooling set for every 10 mins. Before phone went dead, I had the voltage last recorded as around 3200mV. It went to battery charging mode after that and got stuck there at 0% battery without charging.

Not sure if this was an attempt to calibrate the battery, however i have seen this happen randomly (atleast once a week) when I get random discharging since shifting to the first GB ROM.

After rebooting, I got 3057mV at 0% charge. So essentially this proves that even when the phone is charging, it goes dead ONLY BECAUSE of dead battery when the OS keeps thinking that its 100% till the battery is completely dead.
[Galaxy S I9000 General] pwhooftman:
Do i read the graph correctly if i see that the battery drained completely from 100% to 0% in 5 hours? That can't be happening when the phone is idle, so some process must be chewing CPU or generating network traffic (assuming the display is off during those hours). And maybe that process is interfering with the OS reading the battery as well.

Is it wise to start examining rogue processes (if not done already), especially not forgetting Battery Monitor widget itself (maybe try SystemPanelApp instead of Battery Monitor for a while)?
[Galaxy S I9000 General] $omator:
turn off wifi when you do not use phone

when youre in range of known acces point and connected to it wifi slowly but noticable drains battery - its a couple of times (up to 5x) more then in same state with data connection on (conneted but idle)

leaving wifi on idle with no acces point connected = close to 0 battery usage

but anyways wifi on and ap connected would not drain the battery in 5h

you can type in cmd while phone in usb debug mode and connected via usb this

adb bugreport > c:\bugreport.txt

after few seconds you will end up with text file in main path of your pc - you will find out a lot of usefull info in there

Well I'll be.....

Stuck jvq on again yesterday after a while with jsd again. Expected the usual when I work up this morning - unplugged phone, 99%, couple of hours later now and 94%!!!! What the. It's never done this before (act normally I mean).

It's just teasing me. Tomorrow when I get up it'll drop to 70% like usual ;)
[Galaxy S I9000 General] Neried:
Every now and then I will wake up to 100% and I will cringe as I pull the plug out, expecting it to drop to 30% or something ridiculous..... and it is still at 100% (well 99%) then my battery goes on to last 32hrs or something. I think the bug is rectified, plug in when she's low on charge again, wake up next morning to 100%, unplug the charger and doh, 30%.

Going back to Froyo is not an option. God I wish they'd fix this already.
[Galaxy S I9000 General] devilh:
why samsung doesnt do any thing with that??
[Galaxy S I9000 General] goughymachine:
Because unless someone who has an official official release makes a complaint or has a problem there is no problem, can't really complain about an unofficial leaked version. Two nights connected for me now with no issues - it's like slapsgiving - it's driving me nuts waiting for it to happen.....
[Galaxy S I9000 General] keulieminogue:
Me too on official JVI (dbt) ... unplug --> 90%
[Galaxy S I9000 General] Prankey:
I checked it again. I believe Wireless tether of 3G data was on, so that suggests drain within 5 hours. Also, it drains much faster when charger connected.

I also had TWO more such dead battery situation within a span of 24 hours.

One more observation. Before going dead, phone detects 0% battery voltage (from 100%) when the voltage drops below 3450mV. The lowest monitored voltage before going dead is 2962mV and it takes 20 to 30 mins before the phone goes dead after the OS gets the info that it is at 0%. Might be related to FORCED calibration, however, for me its DESTROYING the battery as it had done it THRICE in 3 days or twice in 24 hours!

Right now, when I disconnected from charger at about 3.6V battery voltage (was charging at about 3.9V), it dropped the recorded level from 100% to 8%! So its no where close to 30% or 70%, even when its hardly being used, I don't get anywhere near to 100% I am SUPPOSED to get when disconnecting the charger! Whats going on Samsung?

My battery is performing LIKE NEW as I have observed when charger disconnected. However, it drains heavily when charger connected and randomly my phone is switched off when I am not using it. When it happened first, it was off for 6 hours and I was UNAWARE of it! Might well have lost important calls during afternoon and evening hours.

Multiple follow ups with Samsung only gives a response that they are working on it. I have given them an ultimatum that I need a FULL REFUND if they do not resolve these issues within the next few days. My phone warranty expires in another 7 days and there is NO WAY I am keeping it this way!
[Galaxy S I9000 General] marceli7:
Just to report...

I am on official 2.3.3 JV7 (Orange Poland) flashed by Kies upgraded from 2.2.1.

Checked two scenarios:

1. Charge to 100% then with charger connected run wifi on and Sygic for 1 hour, stop Sygic and then unplug charger. 99% bat status. IMHO OK.

2. Charge to 100% then leave it few hours with charger attached and data connection on. 7 hours later unplug charger= 100% bat status. IMHO OK.

BTW1: I have no kernel mods nor root. I have no other low level system tools.

BTW2: I have no other problems with this rom. Strange! ;) Some users reported problems like not working data connection and bat fast drain. Some users even insist that my rom is broken! Hehe... From my point of view Orange PL 2.3.3 is ok.

BTW3: I am just reporting that I do not see the famous GB bug.
[Galaxy S I9000 General] SKeijmel:
its not a bug its a feature !

and also inceases battery life
[Galaxy S I9000 General] ENO_qc:
Hello,

I turned off the phone

I plug it on charger

I go to sleep

I dreamed habs won the cup

On morning i checked the phone, 100%

I turned the phone on

85%

I dont understand how i.can use battery when the phone is turned off.....
[Galaxy S I9000 General] Peacemanibk:
Charging the phone when turned off always loaded it for me to 100% maybe calibrate your battery ... ?
[Galaxy S I9000 General] goughymachine:
You need to read back through the thread! It's been explained a few times, and happens to many of us. I have taken it off the charger in the morning to everything from having a full battery, to 70%, even 30% once.

It's like when the phone reaches 100% it turns it's charging from the charger off, rather than trickling it or something. But it seems to run hard so it still thinks the charging is on, it thinks the battery is at 100% but it is in fact using battery.

Some test it by charging to 100% notification, and then leaving it connected but doing something intensive like playing games etc and they often after that and disconnecting it from the charger the battery has been well drained.

I've had it when I had my phone charging in the car and using navigation. The phone said full and I just left the navigation and trapster running. When I got home my battery was nearly dead, but didn't indicate that in the car.
[Galaxy S I9000 General] ENO_qc:
I do several calibration cycle..
[Galaxy S I9000 General] goughymachine:
And as an aside, I got a galaxy tab a week ago and have 2.3.3 overcome rom on it straight away and it shows no signs of this problem.
[Galaxy S I9000 General] keulieminogue:
I'm having that problem with JVI-DBT and different kernels using root. Hardcore, darky and talon... is that a prob? Who is having that issue with fully stock?

And please... i think that battery calibration couldn't ve the prob.

Am I wrong?
[Galaxy S I9000 General] rocky23:
batt is issue for gb,it drains more quickly in some roms or specific kernel,iam not happi,i hav done all exp and ave gone thro lot of threads abut any wrong....my moto milestone batt is far more stable than this sgs batt//////////:mad:
[Galaxy S I9000 General] Peacemanibk:
Sorry if my comment caused some confusion - i just wanted to make the point that if you switch your phone off completely during the charging, you should get nearly 100% charge - independend of this bug because your phone is off... if thats not the case recalibration might help ...

I am also having the bug by the way ...
[Galaxy S I9000 General] janish_aggarwal:
Can anyone tell me what is better for phone battery- letting battery go to less than 10% and then charge it fully OR charging in between and not letting it go to critical..

and please tell me when is a 1 battery cycle counted???
[Galaxy S I9000 General] Peacemanibk:
Its off-topic but (from wikipedia germany translated):

It is recommended that Li-ion battery cycle "flat", extending their service life. The unloading under 50 percent should be avoided because it may come with "deep cycle" to larger capacity losses due to irreversible reactions at the electrodes. The battery is aging more rapidly, the larger the cell voltage, so it should be avoided to keep a Li-Ion battery constantly charged at 100 percent.

meaning dont keep it at 100%, avoid to go to 0%, try to stay within 50%-100%. Loading cycles are not that important then for example temperature (the lower the better for battery life).
[Galaxy S I9000 General] tiddydiddler:
I really must question some of the recommendations made on the internet, based on my own experiences.

http://www.hexus.net/content/item.php?item=1452&redirect=yes

I have one of those, purchased new in 2005(currently a few days shy of its 6th birthday). It's only a backup handset these days, but is permanently powered-up and carried around with me. It's on the original Li-ion battery - so 6 years old.

I've always, wherever possible, flattened the battery completely - to the point where the handset will no longer power on, or shut-down mid-boot. It's always been left on a long overnight charge wherever possible. When new, with moderate to heavy usage, the battery lasted a couple of days or so. With light use, it was nearer to a week.

At 6 years old, the phone lasts 6 days between charges, still on the original battery, with very light use - no texting, but around 15-30 minutes of calls. I'd imagine it's had in the region of 6-800 charge cycles, based on infrequent use in recent years but more heavy use in the first 2-3. It'll certainly be in excess of 400 cycles, and in all honesty should be between 6-800.

Far from conclusive, or scientific, but my best guess is it's running at around 70% of its original capacity, if not a little more.
[Galaxy S I9000 General] Peacemanibk:
Well it always depends on a lot of things ... in your case i guess the light usage doesnt stress the battery to get hot which increases lifetime. And when connected to the charger normally your battery gets disconnected after being fully loaded so its not overloading - and to get back to the topic which is not the case in the GB Roms where the charger gets disconnected while the system thinks its still on the charger ...

Any update about the battery drain after full charge?

I also have this problem and it is really bothering me!

Thanks,

[Galaxy S I9000 General] cthonctic:
Hm, this phenomenon is pretty annoying but explains what I have been noticing of late, but only after upgrading to a 2.3.4 JVP ROM. Couldn't say I had it when I was still on 2.3.3. Then whenever I unplugged from the dock it would be at 97 or 98%.

Now I'm starting the day with some <90%, sometimes even <80%. Good thing is, my battery lasts longer now, otherwise I'd push my luck to make it through the day on one charge...

Hopefully Google/Samsung/kernel devs will find a way around this "feature".
[Galaxy S I9000 General] james meek:
I have this bug as well.

I have the same issue using

Firmware Version: 2.3.3

Basband Version: I9000XXJVO

Kernel Version: 2.6.35.7-I9000XXJVO-CL182937 se.infra@SEP-51 #2

Build Number: GINGERBREAD/XXJVO

I use it for tethering whilst staying in hotels (something I've been doing alot recently) and leave it connected overnight to sync files to my cloud storage etc. I have exactly the same issue I noticed it on FroYo as well, but never got around to querying it on here, basically whilst connected (using usb port on my computer) it will charge up to 100% then disconnect the charger, and proceed to run for a good few hours ont he battery until it is so drained the phone powers off, it never restarts the reecharge cycle, and when I come to disconnect my phone the following morning I find that as it has discharged and recharged maybe twice throughout the night I am normally left with a phoen with about a 35% charge for the rest of the day, and most of my file syncing has failed because the tethering got deactivated when the phone turned itself off.

I'm not impressed with the Samsung Galaxy GT-I9000 at all gingerbread has made it a lot better than it was on either ECLAIR or FroYo, but it still has a load of mickey mouse problems, my borthers HTC Desire is a much better phone and the firmwares from HTC seem to be more stable than those from Samsung (dont even get me started on Kies)

Since I've stopped relying on this device as a phone (really only use it as a 3G MiFi now, and for accessing mail accounts that I dont use as much as my primaries), and gone back to my Apple iPhone4 for business use and HTC HD7 (WinPhone7) for personal use I've been much happier, at least when the phone rings I can answer it without the worry of it (a) crashing, or (b) reacting so slowly that the call goes to voicemail.

For such a promising package the GT-I9000 really is a P.O.S.
[Galaxy S I9000 General] keulieminogue:
Now i try to downgrade to froyo - maybe this helps (no... cause 2.3.4 is nice) but i want to figure out where the Problem is...

Maybe this helps for you guys - maybe the "old" gingerbread bootloader helps - it would be nice to get some information!

Hello, I didn't know where to post, this was most similar to my problem.

I installed update to google maps app and now it drains me about 30% of battery even I don't start the app. Does anybody have similar issue, how can be solved?

Is there any app that can control my startup apps?

[Galaxy S I9000 General] goughymachine:
Flashed jvr this morning so i'll see whar happens over the next few nights.

But interesting. Flashed phone at 10 this morning. Reinstalled everything using ti backup (user apps and data, no system data) and started it all on a full battery. Had a look 10 minutes ago and my battery was down to 8% left, with google services at 43% and android system at 23%.

My battery life had been really great since getting my galaxy tab as I don't use my phone for browsing anymore. So I've been leaving my data turned off (tasker switches it on 4 times a day to allow it to sync) and have been getting days of life out of it. So it's something syncing data ghats using the battery up. I certainly don't have the draining issue with my tab like a do with my phone.
[Galaxy S I9000 General] jromz03:
Flashed stock jvr and charged until full. Then leaving the power cable i installed all apps back. Once done i removed the charger aaaaannnnddd... 99%! at least during that it seems the charge bug seems fixed. Will see how it goes overnight.
