I can't believe it...

Will it ever be possible to have a fix for these bug? :(

I feel like the Samsung ROMs stopped coming and that SGS 1 has been left behind. Specially with this mega-ultra-serious issue, that no solution has been found / worked on yet!

What do you think? Should we live with this for the rest of our phones life cycle? I've tried a zillion combinations of things to see if the problem develops and yes, it always do.

Then again, (randomly) 1 in 10 times, after many hours fully charging, the phone retains correctly the charge (98%), leaving me clueless as what is exactly going on...

Hi, I'm using Onecosmic's ICS port beta 2 and this seems fixed. At least I haven't encountered it over a few days. Can anyone else confirm?
[Galaxy S I9000 General] goughymachine:
Yep, I'm on the other ics port and I haven't noticed this bug either any more. Not that I leave it on charge over night any more (got out of that habit due to the drain) but certainly when ever I disconnect charger (or usb) my battery is at 100%.
[Galaxy S I9000 General] Black Rose:
I updated my phone to stock 2.3.3 KG3 a couple of weeks ago and the only way I can get a full charge is to charge with the phone on.

If I charge with the phone off, it does not get a full charge - it will show 100% on the display (most times) but as soon as I turn it on it drops to 95%.

Not sure what's going on with it, but I'm not impressed by it.

Froyo annoyed me for other reasons, but this charging issue is very annoying.

[Galaxy S I9000 General] kalki:
I dont criticize for me its funny
[Galaxy S I9000 General] $omator:
you must drain the battery first to real 0% as sometimes phone reports 0% and turns off but when you power it on after a while it can work for few hours

so then after charging to 100% and reseting battery stats new ones are created for trully 100% charged phone

i know this looks a bit like dancing around fire to make rain on the crops :)

but thats the best way ive found till this day

and what is worth mentioning you would not have eny problem with batstas if you would use kies for updating :]

basicly in service center they would do the same more or less
[Galaxy S I9000 General] Black Rose:
Interesting.

That's the opposite of the calibration routine I found somewhere else on here (involved bump charging and then deleting batterystats.bin).

Problem is my phone will not usually charge to 100% when it's off.
[Galaxy S I9000 General] Black Rose:
Ran the calibration but nothing has changed.

I still can't get 100% charge with the phone off.

It goes to about 97% and stays there, but when I turn the phone on, it says it's 100%.

This only started happening after installing 2.3.3.

Anyone have any ideas on what else I can try until I flash a new ROM?
[Galaxy S I9000 General] Neried:
I am now running XWJVU 2.3.5 and the issue is resolved for me. I can happily put my phone on charge at night and wake up the next morning to 100% deliciously full battery.

Occasionally I have had it drop to 97% after a night on the juice, but meh :)

Oh how often I used to wake up to 22% battery. I have monitored battery use on charge with Battery Monitor Widget and it does hold solid for a few hours, drops to 4053mV and goes no lower, straight back up. Additionally, I use the crap out of my phone, music, games, net, downloading, calling, messaging all day.... usually get home after 12 hours and sitting on ~ 65 - 75%.

Mind you, having some other issues that are pissing me off with JVU, same ones I had with JVT....

Problem solved with Semaphore kernel v 2.4.0
[Galaxy S I9000 General] coolva:
Not for me. I still have this issue. After all night of charging my SGS shows 70% of battery. I m on Darky 10.4 with Semaphore 2.4.0. On Cyanogen i did not have this problem. Any new solution.
[Galaxy S I9000 General] tanivula:
Try the new galaxian kernel. I'm on MIUI but have read that he's used a different source for the charging 'stuff' which has trickle charge once at 100%.
[Galaxy S I9000 General] glaucos:
Do you still have this issue... with semaphore 2.4.0? So the problem/solution is not ONLY related to a kernel version, but this in combination with something else...
[Galaxy S I9000 General] coolva:
So far i had it on every gingerbread based rom. I don,t know what is going on.:(
[Galaxy S I9000 General] shutterbc:
Bump. Yes, I have this issue with Semaphore 2.4.0. Would love to dig in to figure out what causes this but probably don't have the time personally.

I guess it comes down to what is responsible for switching power sources. If I recall correctly, phone is capable of running off of USB power. What logic controls power switching? (bootloader, firmware / baseband... kernel?)

Battery not fully charged, but 100% icon displayed

Hi,

Strange thing happened last evening. My phone was at 12% battery level and I start charging it. Then after about an hour I accidentally look at the phone and I've seen that the 100% battery icon displayed...Impossible, I have the Momax 1700mA battery. So, I look at the battery voltage and was 4.022V. Then I've removed the charger and the battery level drops to something about 40% and battery voltage about 3.8 V.

So, there was clearly a glitch on battery voltage measuring that finished up the charging process.

Every time when I live the phone with charger connected over night there wasn't a big battery discharging, about 95% when charger removed.

I thing this could be happening also to others and the big discharge while charger connected is not true. It is an incomplete charging.

I hope this helps.
[Galaxy S I9000 General] janish_aggarwal:
Problem

When I charge my phone, it sometimes stop charging at anytime( 50%, 65%, 73%) and displays phone is 100% charged. As soon as I remove the charger, the phone gets back to original percentage. Please help. It's very annoying to be able to charge upto only 60% or 70%!!

And BTW this happens sometimes, most of the times I am able to charge it to 98%!
[Galaxy S I9000 General] Prankey:
You should have read the first post and the related screenshots looking at the charging and discharging cycles when randomly it takes the phone to dead battery levels and then only it reads 100% to 0% and still do not restart the charging and eventually phone dies and restart in battery charging mode as the charger/USB was connected.

So its irresponsible of you to name this bug on the calibration issue you faced which is unrelated to this bug! This bug is hit AFTER FULL CHARGE, RANDOMLY on ALL Samsung based GB ROMs! Some of us feel its solved on few ROMs/Kernel only to be rubbished by others!

Due to such random nature, at times some of us may feel that the issue is resolved, but that is clearly not the case and like me, as its really high time, even after the warranty expiry of your phone, you should seek full refund especially if you are severely hit like me. This is truly a global issue and all the GB ROMs from Samsung are affected without question. Either they resolve this by releasing an official ICS release or refund.
[Galaxy S I9000 General] Nel Del:
Tedt so i could search this thread easily through the xda app
[Galaxy S I9000 General] Nel Del:
For some who still dont get whats happening, here it is according to my own experience- Phone stops charging when full and will only resume charging if charger is unplugged and plugged back in. Simple as that. Bug #1.

But then you may ask "Isnt the phone supposed to do that as a battery life saver technique?" The answer is no because its supposed to keep your phone fully charged while plugged in without overdoing it. This is a problem for many users especially those with lots of background apps running. One would not have a full charge when the phone is picked up for normal use.

The confusion comes in when you look at the battery icon at the notification. Once 100% is reached,as long as the charger is plugged in, battery icon stays at 100% no matter what, when in fact its normally draining. Thats bug #2. To get the real battery status, go to Settings, About Phone, Status. Normaly, the amount of drain depends on your the phone activity such as apps running in the background, sync frequency, push notifications, network signal fluctuations, etc. If these activities are kept at a minimal, this explains the equally minimal drain when you wake up in the morning. Big drain is caused by the opposite - plenty of activities like updates, lots of push notifications, and someone sent you an email with a huge attached file and your email app downloaded it at night while phone's "charging" and you're sleeping. Naturally, when you wake up in the morning, you probably have the unexpected 80% power. All this because an engineer decided to turn off the charge switch when 100% is reached and keep it that way until the charger is re-plugged in regardless of what you do on your phone. Add to that the non-updating battery icon and the result is a 1 year old thread in xda.

The ideal charging behavior, just like in other normal functioning computer devices such as laptops and all other phones, is device stops charging when full but monitors the charge. When it goes below 100% charge again til full. Repeat til charger is disconnected.

I dont know whos bug are these - samsung or android. Im guessing samsung coz this doesnt happen to other gingerbread phones (i think). Sad to say no more fix from samsung. Waiting for the CM ICS to be more stable then ill jump in.

I might be completely wrong with everything i said but this has been my observation. Btw, i have not updated my signature yet. Lazy.
[Galaxy S I9000 General] {Angel}:
Thats the behaviour i have with gb as well, except that after it hits 100% and starts to drain on the charger, it drains a lot more quickly, apparently the cpu runs higher as it thinks its trickle charging. Its embarrassing that samsung have not fixed this bug.
[Galaxy S I9000 General] Nash123:
Yeah it is time they fix this bug. Especially as we do not get official ICS.

same issue on r720 (Samsung Vitality)

Just wanted to chime in, definitely getting same symptoms and my own suspicion about why they're happening was close to OP's conclusion about the the phone disconnecting charger and running off battery while GB thinks it's on charger and disables power saving.

Anyway, I've been using the r720 as a media player since I got it in February 2012. I first noticed something was wrong in March when I tried to run a sleep tracking app, which uses the accelerometer and would drain the battery a good amount overnight, so I plugged the r720 in for the sleep tracker. By morning the phone was off and reading 0% charge/wouldn't power on, I think even with the charger still plugged in, UNTIL I unplugged and replugged the charger.

All other instances were just normal overnight charging and getting only 70% battery in the morning. At least for me the r720 was only $35 and I haven't been using it for much of anything (airplane mode, and only occasional music), so I've been letting it drain to 30-50% before charging every 2 weeks, but I finally got annoyed now that I've decided to ramp up using this as a main music player for hours daily.

Found this thread googling "battery fully charged unplug charger", this was 4th hit and all the top results were for "Samsung" devices. Even more surprised when I realized this thread has been around since June 2011. Now I have to see if I can 1) get a custom rom installed on this, and 2) if I can find a custom rom that can fix the issue or work around it. (Kudos if you can let me know real quick, otherwise, more googling for me).

So, ranting at Samsung, seriously, wtf? Apparently the bug isn't limited to one model, since I got it too.
[Galaxy S I9000 General] trololoman:
you're right. use Cpu Spy apk you can find in market and see. as soon as you plug your phone, the CPU runs on 200MHz constantly. It seems that's the problem why it drains so much more power after it reaches 100%, as soon as you unplug it, it goes Deep Sleep/idle
[Galaxy S I9000 General] IWillExplain:
care to read thread from first post ?
[Galaxy S I9000 General] shenoyjoseph:
it was happened with me to i charged my samsung galaxy s android 2.3.3 gingerbread to 100. After 5 mins mine battery dropped to 95%. After seeing this images i clearly understand that background apps are utilizing the ram and processor. So final result is fast battery drain :(
[Galaxy S I9000 General] Prankey:
Hehe, Lithium Ion batteries lasts LONGEST with such short charge cycles. Your thread talks of a battery DRAIN AFTER DISCONNECTING CHARGER which is NOT RELATED! READING HELPS MY FRIEND before jumping to conclusion!

Our phone batteries will DIE VERY SOON if we believe your logic that the phones should be left to go DEAD after a full charge despite connected to charger!

Earlier than GB builds used to DISCONNECT BATTERIES after full charge and run the phone on charger only. GB builds do it OPPOSITE. Someone from SAMSUNG has GOOFED UP the logic after stopping charging cycle of the batteries.

Instead of disconnecting batteries and using the phone run on the charger, now the SAMSUNG PHONE drivers disconnects the charger instead and use the batteries. GB OS still thinks its running on CHARGER (as per the design) and hence report 100% charge level till the phone dies due to dead batteries!

Hope this makes you understand the SERIOUS NATURE OF THIS BUG which YOU believe is a feature of GB!
[Galaxy S I9000 General] Prankey:
You are also mistaken. Battery calibration is needed only to RECOVER some ACCIDENTALLY lost capacity due to error in recording max and min battery levels.

Issue here is - phone disconnects the charger and runs on batteries as soon as the batteries get full charged. It worked the OTHER WAY ROUND on earlier than GB builds and that is how all OTHER PHONES WORK!
[Galaxy S I9000 General] $omator:
=) i am guessing but your attitude is ok. concentrate it on samsung not xda forums and you might get somewhere hehe ;d

personaly i do not see a problem with such setting, have not noticed it was 'the other way'
[Galaxy S I9000 General] Prankey:
Well you earned it :) (though I sincerely appreciate you educating other members on other important issues)! Your replies to this thread is like running salt on the wound! As you know, its best to charge/discharge a max of 10% in each cycle on a lithium ion cell.

If I switch back to Froyo or Eclair, all works like it is supposed to be.

I have already taken this up with Samsung on priority.

Why would you think a phone will disconnect from charger and drain the battery COMPLETELY after that? Do you expect us to disconnect/reconnect charger every few hours to stop getting the phone dead or seeing close to 0% charge after disconnecting the charger?

How do you expect to use the phone when using it heavily like when using GPS or WIFI/USB Tethering? You want it to use battery heavily (instead of charger) and eventually die even when connected to the charger/USB? Do you want us to disconnect the charger to see 10% battery level and carry the phone that way? Or want us to see the phone switched off any time of the day and running offline battery charging routine?

I would appreciate a reply from you on this as I am here to educate other members from this danger as every deeper than 10% charging/discharging cycle due to this bug is KILLING OUR BATTERIES and PHONE (due to overheating from such deep charging cycles)!
[Galaxy S I9000 General] $omator:
it is very hard to drain the phone while using it - even with my heavy usage i get easy 1 day

only way i see here is using sgs as a point to point navigation - but as gps sucks realy bad i do not see many people using it as such navigation

well ofc connected wifi also drains heavy but i just dont use it and do not get such problem =)

i do not see much sense in using phone while connected to charger, but i might be an exception

only as mentioned above

well i need to read a bit about this batt / gb / test some

and i will be able to say more
[Galaxy S I9000 General] PissPot:
I'm new so please go easy on me n I apologize if this is a stupid question, does this apply to custom roms that are based off froyo but emulate gb?

I'm using miui rom which shows 2.3.4 on jvk

I haven't really noticed anything but just thought I'll ask. Thx
[Galaxy S I9000 General] Prankey:
That is the reason why most of the people do not notice this bug - they almost never use the phone after it is fully charged and plugged.

However, when you play 3D games, use GPS and Tether 3G over WiFi or USB, it gets very hot and certainly needs power from the charger. Even the charger gets hot with such usage.

Now imagine what do we witness on a GB ROM - significant battery drain after full charge with phone shutting down randomly due to complete battery drain. My phone is almost always used as a Wireless Internet Gateway and hence most affected by this bug (as I have to leave it plugged to save battery from such abuse and keep the phone alive). Despite using my phone for almost a year now, my batteries are healthy with close to 100% capacity giving me more than 1 day of moderate usage like you. However like any regular user, logically, I prefer using the phone on charger (like a laptop) when using it heavily and keeping the battery charged.

This issue will impact you even when you leave the phone idle and connected for several hours (12+ hours) and you would still see the drain. Infact the phone will go dead even when sitting idle and connected for more than a day or so (after regular standby when running on batteries).

Test your phone by completely charging it and while the charger is still connected - use it heavily playing 3D games like NFS, GPS, playing video, Web browsing, Video chat, etc. (you would obviously want to leave the charger connected during such heavy use to protect your battery from such abuse). Disconnect after an hour or so and you would know what we are witnessing.

That is the reason why I STRESSED to closely TEST your phone before reporting that you are not affected by this bug or before jumping the gun by treating it as a "new feature" of GB ROMs.
[Galaxy S I9000 General] goughymachine:
Since going back to eclair, and now trying jsd my problem has gone. I was waking in the morning often with less than 70% of battery left after unplugging my charger. I don't get a good signal at my place. On eclair when looking at my battery usage my cell standby was often using more than my display, and would often show close to 15% of the time with no signal.

JSD is fast enough for me, and since I use go launcher having some of the gb features doesn't mean much to me. Can't wait for them to fix it though.
[Galaxy S I9000 General] Prankey:
If you use any Froyo built ROMs with GB themes, you will NOT be affected. However if you use a ROM from Samsung built around GB, you will be affected.

I have not used MIUI or CM7 ROMs till date as they still do not have full functionality like a Samsung Base ROM. So, can't comment on it.

You could test it yourself by heavily using the phone for an hour or so and disconnecting the charger after that.
[Galaxy S I9000 General] Prankey:
You could use Froyo as well. Only GB builds are affected.
[Galaxy S I9000 General] goughymachine:
Jsd is froyo ;)
[Galaxy S I9000 General] pinoypower:
I have been on different GB custom roms for over a month and I had this problem since I started using GB. I've noticed however that charging the phone via pc doesn't do this. The charge stays at100% for sometime after disconnecting the usb.
[Galaxy S I9000 General] ferow2k:
I do have the same problem when charging via USB.

I'm attaching a screenshot of the battery history (from Battery Info Widget) showing the "battery jump".

Also, it seems that the rate at which the battery discharged was much faster than when disconnected from the charger. See the red line I added for comparison.
[Galaxy S I9000 General] Prankey:
No luck for me even through USB cable. If the phone is connected for a couple of hours while I am using it via USB, as soon as I disconnect, I get the real percent around 50% only.
[Galaxy S I9000 General] Prankey:
Seems more people have jumped gun without thoroughly testing as recommended. Thanks for the screenshot, really helps.

Reason phone use more battery after full charge when charger is connected is because of the explanation I have posted in the first post:

Phone OS "think" that it is running on CHARGER ONLY (instead of battery only - due to this bug), it drains more battery by disabling any battery optimized performance tuning (like running CPU usually at max clock, max power to wifi, etc.).

This is the reason I have been WARNING everyone to immediately report to Samsung as this bug is really killing out batteries. I hardly used my battery before GB as mostly used phone when plugged (primary use at home is Wifi Tether and outdoor is GPS). Hence my battery is still performing like new without any noticeable reduction in capacity, however since past few months after the first GB beta came, my battery has been most abused and Samsung should actually replace our batteries after such abuse due to this bug.

Whenever I have to use the phone heavily, I keep it plugged in to save battery, however GB is doing other way round by using battery when charger connected, destroying it in the process. The least we use the battery each day, more would be the lifetime due to shortest charging/discharging cycle (battery is disconnected after full charge on Froyo so the only loss after that to trigger "tickle" charging is its own internal resistance).
[Galaxy S I9000 General] Prankey:
That was what I was wondering, you kept talking of Eclair and also referred JSD. Thanks for clearing the confusion ;)

I dont know why multiquote is not working for me (gives a blank reply box if I try).
[Galaxy S I9000 General] arnoutzw:
Using your phone while battery is at 100% and very hot is second worse thing you can do after deepdischarging.

That reduces capacity quickly
