Hi guys. Today when I was trying to charge my GS2, there was popup said 'battery disconnected'. I've tried to take out the battery for a few minutes, but the problem has not been solved. I am running checkromv4 and siyah kernel right now, just updated to siyah 2.6.12 last night. Can anyone help me? BTW, I am using the stock battery.
Are you able to charge it ? If you are (even tho this probably won't make a difference, but it might), charge it to 100% & delete battery stats in RedPill Recovery.
If this doesn't work (probable), try an earlier build of Siyah. If that doesn't help, go back to stock firmware & see if you can reproduce the problem. If you have no problems with stock, then it would obviously be a problem with that build of Siyah or your rom.
If you still have the problem running stock firmware, it would probably indicate a problem with the battery or something else hardware related. Perhaps try another battery. Failing that, back to Samsung/your telco for repair.
just take out the battery again this afternoon for ten minutes, and the problem seems like sloved so far. I can charge now, but have to take a try tonight. Thanks for your help.

This is an old thread, but I recently had this same problem with my Galaxy Note i717. After worrying about it for awhile and searching to find this thread, I took my battery out and examined it, and of the three terminals, the middle one had a piece of plastic broken off of the battery, covering the terminal. So the phone was getting power, but apparently couldn't communicate with the battery, and so for its own safety, wouldn't let me charge
Hopefully this helps someone else!

EDIT: Also I tried charging to 100%, and clearing the stats etc, to no avail.
battery disconnected simple fix
pull out the battery take a 12v battery of your car or UPS touch the terminals -+ to your phone's -+ as - to - and +to+ remember just two or three times kisses only . now put battery back in phone Done....
First....why revive a thread that no one has visited in over 3 years.....
And second.......seriously? Connect a high capacity 12 volt source directly across the phones battery terminals?
To whoever reads this.....
DON'T EVER ATTEMPT TO DO THIS.....
It is EXTREMELY DANGEROUS and incredibly stupid to even *think* of doing it. It WILL destroy your device and it will likely cause you to suffer burns and possibly start a fire.....

I was flashing a new rom. And after it said 100% on the phone it turned black and never lit up again. I waited i didnt pull out the usb. 15 min later i checked it again still black. i pulled the usb out. hit the power button and nothing happend. i did a hard reset and still the phone wount power on. The phone's charging led light wount even come on when i plug it up. So i assume i have bricked me phone ?
I have HSPL3
miri19v
froyostone 3.1v
is there any way to bring it back to life or do i toss it in the trash?
thanks for the help
i have also tried to go into boot loader and NIL!
from your use of the word 'trash' can i assume you have a tmous hd2? if so, what did you flash? was it a non tmous stock rom (meaning a bad radio)?
(oh, first job tho, check for bent battery pins)
the pins are fine. yeah i was actually flashing a stock tmou rom.
got the full filename for the rom you downloaded please? (just checking you havent downloaded a t mobile rom that isnt tmous)
the reason im pushing that line of enquiry is that the symptoms you describe are consistent with either
wrong radio (from the wrong stock rom)
bent battery pin
over discharged battery
to test the over discharged battery you can take it out, plug usb in with wall charger, then put battery in. this lets it charge without trying to turn on the phone. the light may not come one for some time, so leave it a good hour or two.
Hey Sam,
I'm having this issue too. I am relatively positive it's from an over-discharged battery. The phone conked out a few nights ago, and later when trying to charge it I got nothing - until yanking the battery for a bit, plugging in the charger, then popping in the battery. Now, every time the battery drains I have to do this.
Is the battery "damaged" now, or do you have any suggestions to fix the prob? I see this posted a bit but no one has any solutions that I've found.
Thanks!
Ryan
well i know the principals of these batteries, but not really the mechanics, so yes id guess the battery is defective, (but it could be the phones internal battery control circuits too, again just guessing) but no i dont know if there is a cure, other than try another battery, and if it cures it, ok, but if not then it would be a warranty issue.
are you using android? cos from what ive read it discharges quickly under android or something? (never used it so cant tell)
Hi,
I am very new to the Android world. Got a SGH-i777 from AT&T in US in February 2012 and had to move back to India in June. I got the unlock code from AT&T and used the device for 2 months without issues here on the local network.
Yesterday, the phone showed me a critically low battery message all of a sudden (I had fully charged it the night before) and turned off. When connected to the charger, I get the image of the battery with a yellow triangle with an exclamation mark in it.
Thinking it may be a battery issue, I took it to a local Samsung repair center and he tried using a working battery in it, but still got the same image. He suggested that it may be a motherboard isssue.
Please help !!! I am still in the AT&T contract.
It happened also with my I9100 but i just continue to charge the phone and it disappeared.. try it

Just a thought. There are a lot of non-nfc batteries around. Are you sure the person at the repair center used the proper battery. The I777 must have an nfc battery. Worth checking out. May still just be the battery failing.
I guess you continue charging it. Are you on a stock rom?

I will certainly try it out. I will charge the phone for the entire night and check it out in the morning. Thanks for your reply. BTW< how long did you charge your I9100 when you faced this problem?

Sorry, I am still not up to speed with the Andriod lingo,so didn't fully understand the word "stock rom" but I have not rooted the device if that's what you are asking. I will continue charging it and check after some hours. Fingers crossed..:angel:

Hmmm, I am not sure which battery he used. Will try a long continuous charge first and if it doesn't work will take it back to the repair center and check if he has an NFC battery. I hope it is just a battery problem and nothing more serious. Thanks for your reply.
An update: I charged the battery for the entire night and got a 100% charged indication in the morning. But when I disconnected the charger and tried to turn on the phone, I have the same issue. I still get the yellow triangle with the exclamation mark.
But this time around, I was able to enter the recovery mode by pressing the Volup+VolDwn+power key and I rebooted the phone from the recovery screen and it worked fine. I am able to run the downloaded apps, make calls etc.
Now, I notice 2 new things:
1) Every time I turn the phone off or when it turns off automatically (which it does very frequently since today), it doesnt restart normally. I have to enter the recovery mode to reboot the phone and make it operational
2) When the phone is turned on and when I charge it, no matter how long I charge, the charge percentage shows 78% always.I guess the only time I get a full 100% charge indication is when the phone is turned off and then charged.
All this is leading me to believe that there might be a problem in the battery. If the phone operates properly from the recovery mode, I guess there is no issue with the mother board. Any ideas?? Please suggest.
I can make some observations. Please bear in mind that anything I say is speculation, basically guess work.
From your description, it sounds like a problem with the battery charging circuitry. It doesn't sound like just the battery itself, but that is the easiest thing to test, by getting a new or at least different battery and trying it.
As far as the battery circuitry, it could be either a hardware failure problem, or a firmware problem. Are you still running stock firmware or have you customized the phone? And which firmware version does it have? If I had the phone, I would reflash the stock firmware to see if the charging issue clears up. If that didn't fix the issue, then I would suspect some form of hardware failure.

Is that something common? I have had an extended battery for about a week with no issues. As far as I know, it does not have intergrated NFC antenna (or chip...seems a subject of debate whether or not stock batter contains just the antenna or chip too). Anyway, I bought the batterny knowing the feature wasn't there. Unless by some fluke a tthe time of order I happened to get an updated version of the battery, but I seriously doubt it as there is not any indication on the battery itself that it does, aside from having 4 prongs. Which leads me to believe with the right materials I can create my own antenna and slap it on there....assuming people are wring with the whole chip thing. Just thought I'd mention since I don't have NFC and don't have that problem...and now curious as to why you suspect it for affect battery charge and the sort.
Hi guys,
My battery life was getting shorter and shorter. So, I decided to buy me a new battery. I tried the battery and my phone turned on with the green charging battery.
As I turned my phone on when it was filled 100%, my phone gets stuck at the beginning (black screen Samsung galaxy blabla with the yellow triangle)
I thought this was weird so I started it in recovery/download and this does work.
After choosing for reboot I got the omega rom loading GIF, and suddenly I got KERNEL PANIC UPLOAD MODE.
I decided to try a battery from a friend (also Gt-i9100). This battery just worked in his phone so why shouldn't it work with mine.
As I tried it, I first got the message battery too low. But the battery was full in my friends phone. So I tried again, also stuck at the beginning screen.
To make it even more stupid: My friends phone wont boot either after I used his battery.
As I was really tired of this sh*, I decided to put my old stupid battery back in my phone so I could use it for +- 6 hours a charge.
Now my phone is stuck at the beginning with all the 3 batteries.
I tried to re-flash my omega rom, but it's still the same issue.
Is there something going on with my kernel? I thought I could erase the battery stats, but thats not a option in this CWM.
I'm really stressed, because like all of you, I need my phone every day.
Do you guys have any advice, tips or sollutions for my/our problem?
Searching and reading the topics that already discuss the points you made would be a start. :good:
Kill the phone, it's evil.
Regards.
Mark Battery.

Maybe there is something faulty with the battery inferace of the phone or maybe you're just unlucky. I don't understand why your friends phone wouldn't boot after you used the battery - that doesn't make any sense - but either way, I'd order a new battery from a reputable retailer, if it stops working again in a similar way then get the phone fixed/replaced.
My suspicion is that it's either a fault with the phone or that there is something you're not telling us. I can't see how the battery (hardware) could cause your ROM (software) not to work unless the link between the battery and phone is damaged, in which case you need to replace the phone.
Hey Everyone!
I have an S2 with some trouble...
The phone was not charging at all, kept discharging even when connected to power, so I suspected a Charging system failure...
I proceeded to get a new charging port, and the battery would charge up to 60% and give an error (Battery Disconnected), tried a couple of charging times, never got a good battery life, phone was shutting down unexpectedly...
So, it was time for a new battery, bought the battery like 3 days ago, inserted the battery, tried powering on the phone (hoping the battery would hold some power), it didn't power on at first, kept doing my stuff, and like 3 hours later, I connected the phone to the computer to get some power, and it was powered on already...
Now, the battery life is quite good compared to what I used to have with the other battery, but whenever I power off or restart, the phone will keep turned off... If I connect a charger, the phone will boot and tell the battery is 100% charged...
Now, If I shutdown, remove battery, put back on and turn on the phone, it will boot from time to time, getting a massive battery drain, powers off by itself, connecting the charger without power on, the phone will display a full battery...
Any help will be appreciated!
Kernel Siyah 3.0.31 s2 v6.05b+
Roshnaie Rom V4 LSW
PD: can I try ICS back in this device???
If I remember correctly, updating through kies would repartition the device, and I dont know if ICS would be compatible with that (used disaster Rom before on another i9100 i had), also, I ignore the method used to update
Yep, do a clean install of stock in the first instance & test. Are you sure you bought the exact same revision of USB board that was already in the phone ? Often problems that persist after replacing the USB board are caused by this. If you didn't, you probably want to buy another USB board & replace it again, but use the exact same revision that was in the phone initially. Check KeithRoss39's guide in General for the info you need.

K, will try a stock ICS, feel a lot more confortable with it for trying out the battery stats...
As for the USB board, originally had R2.2, only R2.3 is available everywhere I ever looked for it, will need to order from somewhere else, but the shipping will cost like 1500% more than the actual board, will keep digging around the junkyard
The difference in the board revision might well be causing your issues, but hopefully it's just something funky in the rom install you've currently got. If it's OK on stock, do a completely clean install of your custom rom & test that for a bit.
And if it's not OK with stock, you know what to do.
Hi!
Have you checked your battery? Maybe your battery has some problems. Actually, one of my friends had the same problem..... He purchased a new battery and a new charger for his S2 and fortunately, his problem was gone!
Please thank me if i helped you!
'So, it was time for a new battery'
And so the 'nobody reads threads before posting on XDA' thing continues...
As @MistahBungle says.....get that board replaced for the correct version. I would personally avoid Odin flashing a phone that I knew to have the incorrect USB assembly. I'd also advise you to think long and hard before flashing stock ICS to your phone......if you want to know why.....do a search for "emmc brickbug".........
This might be my S2 or it might be my W, but it's definitely CM...
Hi,
Here is my problem hope some one can point me in the right direction.
Problem is that the phone is draining the battry when it's turned off (shut down) from 100% to 0% in less than two days and it's not even powered on!:crying:
I did try with two original batteries which works perfect on other S2, as I have another S2 wich I can do test with. So battery problem is discarded.
Then I flash back the phone to the last Samsung I9100XWLSD_I9100FOPLS4_I9100XXLS8_HOME.tar.md5 stock ROM to see if it solves the problem, maybe due to a bad ROM or kernel. But it doesn't solve the problem.
Phone charges fine, it reach 100%, never got wet, when it's powered off it doesn't get warm so no short circuit involved.
I'm running out of ideas, I did read all the posts I can find about this matter but can't find a solution.
Does any one have an idea on what can be this or how to solve it?
Thanks in advance.
