got this tonight,
let the battery get down to ~10%
plug it into the OEM USB wall charge and cable, "battery disconnected"
plugged it into my PC with standard micro USB cable " battery disconnected"
pulled out the battery, and now it seems to be taking a charge, is this something others have seen? is a brand new phone on the first battery charge
Charge over four hours to 100%.
Still a problem return it to the seller .

If it says 'battery disconnected' it probably means that your battery is not touching the pins properly.
I had the same problem and i put a small wad of folded paper behind the battery and then slid it in its place. The battery is now pushed firmly against the pins and voila! the connection is proper and no more 'battery disconnected' !
Hope this solves the prob, if it hasn't already been solved
Same situation here, used some contact spray and problem is soled so far.

Replace USB board/port. Search for KeithRoss39's guide (it isn't stickied, do a search for 'replace USB charger board' or similar). This is quick/cheap (US$10-$15)/easy to do, Keith's thread has all the info you need.
Dont worry
Hey, This is not a big issue. If you get a message as battery disconnected, then it probably means that you have to turn off your phone and take off your batter and put it back. Simple.
If you see same result again, then just simply buy a new batter. I have faced with this issue but now is ok after just taking off and putting it back.
All the best
Check blogowebgo.com for more tips

Took a Q-tip dipped in 91% alcohol and rubbed it to the contacts on both the battery and the phone. No more error. Battery appears to be charging, no problem.

Thanks alot
none of the above worked. looked closely at the contacts and realized there was a thin plastic strip on top of the contacts to protect them. a bit hard to remove the plastic strip, but then the battery was no longer "disconnected" of course

try not to force much the contacts of the usb port or you will be without MTP connection (as happened to me, you can only charge the phone)
My battery's been on the fritz for the last days now. Whenever I turn my GS2 off, it will shows tha battery charging screen, then flash to another icon that shows a battery, exclamation mark in a yellow triangle, and a thermometer. It had to plug the charger in to get it to turn on, even though battery was at 100%.
So, I decided to download Battery Doctor to check my batter stats, and it says 'Health: Over Voltage'.
Does anyone know how to fix this? Help would be much appreciated.
I have exactly the same problem. I have not found a sollution, am thinking of calling samsung and explaining the situation. I will post here if i have a sollution.
What OS version are you running?
What Kernel version are you running?
What carrier (if any) did you purchase the phone through?
I'm on 2.3.3 (KE7), using Chainfire's kernel. Phone is carrier unlocked, unbranded from clove.co.uk.
Btw, I think I may have fixed it. I discharged the battery and used a charger with a lower voltage output to get it fully charged. (Charger I used if from my spare phone, a Samsung Champ). It now says that my battery health is good.
Now, the problem is that my phone won't stay powered off when I turn it off. It will stay off for 1-2 secs and power back on. Even if I remove the battery, the phone will power on after i place the battery back without me touching the power button.

I have the exact problem. Is the battery health still good? I would like to fix this by myself and not send it in and be without my GS2 for that time.
You should try this:
1. be sure, that your battery is full (charging over night)
1. run the app battery calibrator
2. unplug charger
3. drain battery all the way down till it shuts off
In this way your phone can remember what is 100 % and what is 0%
My sgs2 shows 4,194 V at 100 %
I think your stats (look into battery calibrator) said that 100% are for example 3,8 V
PS: You need root permissions
---------- Post added at 04:55 PM ---------- Previous post was at 04:49 PM ----------
Please post us your current voltage.
I have this exact problem. Battery Calibration is pointless, we all know that.
Did anyone ever find out if this is fixable, or do I have to contact Samsung for a replacement?
It's quite annoying that I can't turn off my phone, it just powers on after about 2 seconds. In addition, I never know how much juice I have left in the battery as the reported capacity can jump from 90% down to 6% in an instant. After a reboot it might go up to 12% but I can still use the phone for hours without it shutting down...
Yeah
I've been having the same problems as all above...
Galaxy S2 on Sensation rom, but its not the rom, i flashed to another and the problem still remains...
It all started with phantom charging...(charging when the charger is not even plugged in and constantly making the "charger connected" sound)
I got the phantom charging fixed by cleaning the charger port with a cotton bud and some cleaning alcohol...But now i have overvoltage...
And just like the others, it'll stay on for example 100% and if you reboot its suddenly on under 10% and slowly works its way up to 20 or 30% without even being charged.
I'm assuming the battery got messed up during phantom charging, in tthis case calibration doesnt help, nor does flashing another rom. Flashing another rom leaves the phone stuck in MTP mode therefore unable to use it as a flash drive.
A vid on youtube reccomends replacing the part of the circuit board to which the charger port is attached and as well as the battery at the same time as the battery always gets messed up with the overvoltage issue....
When i have overvoltage i cannot charge even when its under 10%, unless i leave the charger in and reboot the phone it will then charge once it comes back on and it even says GOOD HEALTH until i unplug the charger.
I'd really like a definite solution to the overvoltage issue...
Bump!
Did anyone find an answer to this problem? Mine has started exhibiting the same behaviour. I haven't been able to search out any solutions...
Cheers, PF.
EDIT: Whoops! Just realised I'd better change that signature to SGS2-able. lol
I am also seeing the same issue for the past 3-4 days, I have switched off the phone and took out the battery, planning to visit samsung support center.
I hard rebooted the phone(which reset it to factory) that did'nt help.
will update once I get more info/help from Samsung support.
Vikas
i had the same problem as you guys and i fixed it by cleaning the contacts on the phone where you connect the charger. use some cotton buds and a needle and some alcohol and clean all the contacts at the bottom of the phone (usb cable slot).
make sure phone is turned off tho whilst doing it. that fixed my over voltage issue.
Hi Guys,
I went to Samsung Mobile Support Center today, they told me that USB mini port has turned slightly green, which means that it has in contact with Water
this will not be covered under warranty and might need to be replaced with charges
Tomorrow they will tell me the exact cost.
I still believe, its not an issue of Power port but with the battery port.
will update if I am able to get it solved.
It's a problem with your usb charging port. The only way to truly fix it is to have the charging port plus circuit board replaced. Happened to me a week back and I tried virtually everything- stock roms, removed root, replaced batteries etc. None of that worked. Some posts said it was a port problem. Went to a tech guy I knew and he confirmed the issue when he disconnected the port. It was relatively cheap for me to fix but some people have climed that samsung charges a large amount to fix it. You're better off trying to get it fixed on your own. If you're on warranty, try and claim it.
Also alot of people are having this issue- yours is about the 5th topic I've seen about this problem this week
Hi Guys,
My problem is solved. Samsung support replaced charging port and the chip it was in(total cost 650/- INR, about 13$)
now phone is working as before.
i have the same problem on my gs2, so can i fixed this problem by cleaning the mini usb port?

Cleaning the usb port will/might help with phantom charging , but not overvoltage.....
For Overvoltage you may need to replace the whole USB port part of the circuit board (easily obtainable on EBAY) and you have to replace the battery at the same time as well cause the battery (also easily obtainable off ebay) gets damaged with the overvoltage problem.
I have ordered both about a week ago, awaiting 3 weeks for it to arrive to my country.
Good luck with that...
Theres videos on youtube of how to do the repair for overvoltage yourself...
Will report back here if circuit replacement worked for me...

When you open your s2 for the first time it is tough, but after that it is very easy...
I have already opened mine before to replace the loudspeaker, so it is now easy for me.
Heres the video of how to open your s2:

Heres the video of how to replace the charger port circuit:

(or do a YOUTUBE search for "Galaxy S2 USB Flex Cable Replacement ")
This video also has comments that explain the cause of this problem...!!!!!!!!!!
That is the part you need to replace, the USB FLEX CABLE...(its the ribbon cable and the board, but they call it a flex cable)
Hope they help you.

Thanks, but the problem is solved by cleaning th usb min port, i no need to replace the flex cable anymore,.
I got a wierd problem. My galaxy S2 refuses to shut down.
When I shut the phone down without a USB cable connected then the phone turns black and the 'menu and 'return' button lights up then the phone vibrates. at this stage before the buttons turns black and the phone was totally shut down. now instead the buttons are still lit after the vibration and then the phone starts up again.
With a USB plugged in after the vibration when shutting down I get to the screen where the battery indicating charging is shown, but as soon i remove the USB cable the phone starts.
I got a youtube clip showing all this and I will update the post as soon the 'audio swap' is done.
The power button is not stuck.
It's not rooted:
Code:
Android version: 2.3.3
I9100XXKE7
2.6.35.7-I9100XWKF3-CL276555 root(at)DELL101 #2
GINGERBREAD.XWKF3
I cleared the cache in 3e recovery. No change.
I fully charged my battery. No change
I drained my battery to 0%. No change
I tried another battery. No change.
What's the deal? Does anyone know how to fix this problem?
I'm asking this in order to avoid sending the phone to service since it most likely will be gone for a couple of days. I will not try stuff involving rooting the phone since I need to have the option of sending it to service without them refusing the phone due to rooting.
/Anders

The deal is as always step one backup your data and via recovery factory reset .
Saves the service centre doing just that and may fix the problem .

Hello,
Factory reset was one of the options I was trying to avoid. However I just performed a format/factory reset. And the problem is still there. When I shut down the phone restarts.
Also to add to the confusion the phone can also enter a state when I'm in the battery charging screen (Not booted phone) when a thermometer with a warning sign is pressent. However, I have waited for hours with the battery unplugged and everything is cold. That warning seams wierd to me and might be the root of all evil. That screen is pressent without a USB cable plugged in and that is also abnormal.
Any other options?
Thank you for helping.
/Anders.
I recorded the problem.
I cant post links in this forum due to:
"to prevent spam to the forums, ALL new users are not permitted to post outside links in their messages. After approximately eight posts, you will be able to post outside links. Thanks for understanding!"
but paste this search string to youtube

Have you tried to hold down the Power button for 8 seconds? OR a battery pull for 10 minutes?
Regards.
yeah you should try and pull out the battery...
i had the same problem after I used the JIG on my phone.. it refused to shutdown, and kept rebooting it on each try to shutdown..
i pulled out the battery for awhile, and plugged it in and out to the charger..and it worked.
if it's still nagging you, try flashing a new kernel
Yes I tried pulling the battery and also used a battery from another S2 without any changes in the behaviour.
They talk about this problem at androidforums
androidforums.com/samsung-galaxy-s2/377331-spurious-battery-temperature-warning.html
Seams like there is no known fix for this problem yet.
I turned in the phone to the local service center today. We'll see what they say.

Maybe your power button is faulty or stuck. Do you have a case? Is it somehow holding the button down after you release it?
Sent from my GT-I9100 using XDA
Generally this is caused by a dirty or faulty USB port. Shorts on specific pins with specific resistances will cause different behaviors.
Try cleaning the port with a dry clean toothbrush. If that doesn't work, take out the battery, and try cleaning the USB port with a q-tip and a small amount of rubbing alcohol. Then let it dry before putting the battery back in.

I've already tried it and no luck. The technician told me that it is the USB Port problem sometimes also because of overcharging the phone. The USB Port can be fixed immediately but the problem is my SGS2 is a Korean S2. They told me that the port is different from the one's that they have here in the Philippines. Is it true?

Even i used to have these problems. Phone shows charging or usb cable connected for no reason out of the blue. Device wont simply shut down and would start up again.
What i did was perform a hard reset. Pull the battery out first and clean the usb port a lil bit. After some time it vanished

Until now, it's not happening to your S2 again? How did you clean the USB Port again?
Well nothin much...i just took a little cotton and cleaned whatever i can. And then i kept the phone off for about a day or two. And when i switched it back on voila the issue had disappeared
The only problem am facing now is the home button issue taking me to voice command. But then again i froze it with titanium backup. No issues after that

And yeah...been 8 months since i last encountered that problem. Another thing is i used to Yank the device out from the usb/charger cable when plugged in. Now i carefully remove it without much force. Maybe that helped too. Just saying

My SGSII has developed an issue over night.
When I unplugged the charger this morning it stayed as being on charge and the Battery 100% symbol. It randomly flashed up as charging 3 times in a couple of seconds. It can be fine for anywhere between 5minutes and a few hours and then states on charge again.
I have taken the handset appart and can see no liquid damage and the solder on the micro usb port are all good (no dry joints etc) I gave it all a good clean down with IPA.
Since this morning it has done it several times but seems after the battery drops below 90% it no longer does it.
Any ideas on what to check next? known charging issue? possible battery issue?
Please clean your usb port on the phone using canned air or a dry brush. It's mostly a problem with the contacts short-circuiting!

Tried, also used IPA to make sure no residue is on the contacts.
It's strange it hasn't done it after the battery dropped below 90%. If it was a short it'd be doing it all the time.

I tried different chargers and another battery.
My brother told me that after i updated my phone he saw something like "Charging paused. Voltage too high" but i havend seen it anomore.The battery on options menu says "1 day 8 hours 16m 33s on battery which is not normal i thing"

Hmm , can you tell me how to clean the port or what to use not to bent them and one more thing, as i can see the pins are so small so how do i know if one of them is bent or not
,,,
tried cleanin the port,removing the battery for 20 min and still the same
its port problem, i tried fixing myself but didnt work, i had exact same problem, i sent it in for warranty, and samsung just sent my phone back today, and they replaced "usb port" according to receipt
"Cyber Clean" did it for me, was able to get in to the tiny spots and pull out the dust, etc. that was causing the problem.
DO NOT try to shove anything hard (Like a Q-Tip) into the space, it will break the connection.
You can also place a *newish* USB port in and out a few times, often that can dislodge whatever got in there.
BE VERY GENTLE as this is the weak part in the phone. If you break this you will need to use a wall charger.
i tried cleanin with a lot of things and it seems to be so clean now and the pins are not bent , but i dont think that the problem is at this part because when the battery goes under 60% everything returns to normal ...
I also have the same issue...is it the hardware or software issue?? kindly assist....
This is called "ghost charging". It has dozens of threads already, use the search before posting.
