I was having a similar problem with mine the last week or so.

when using stock rom It would think its is charging when it wasn't , would constantly jump between "Charging (USB)" and "discharging".

I also saw the battery with a exclamation mark next to it some times when trying to boot.

I tried installing ICS leak and was getting a "battery over voltage" message, whilst still as jumping between charging and discharging

I also cannot turn the phone off, it comes on straight away with the battery charging symbol

I tried cleaning the usb port but it made no difference, so I booked a return this morning.

it seems that it doesn't matter what rom/kernel I was using, imo definitely hardware related.

hopefully Amazon get me the new phone quickly.

[Galaxy S II Q&A, Help & Troubleshooting] march83:
i ordered a couple of different usb boards from various sellers on fleabay and i received the first of them last night - it was marked as follows:

the installation is quite easy - remove the ~8 screws from inside the battery cover, pop the casing open (it seems easiest starting from the sides near the volume rocker or power button), remove the 2 screws holding the usb board and 1 screw from the long finger of the mobo (so you can slide the ribbon out), disconnect the aerial and usb board plugs and then pry the old board out.

replacement is the reverse, again fairly straight forward. unfortunately with this board the 2nd of the usb board screw holes did not line up with the mount so i temporarily left it out.

once put back together, the unit powered up and ran well for a little while (no CPU hangs, sleep to death or random car mode/cradle switching) but unfortunately it wouldn't accept any sort of usb connection. i pulled it apart and confirmed all connections were ok (which they were) and i put the old one back in.

my phone is a relatively early release australian delivered unit and the original board was marked:

I'm hoping that one of the other units i've ordered is a 2.2 as i'm optimistic that one of those will work...

I have the same Nightmare problem.

The phone does not shut down. When i try to shut it down it turns back on after 2 seconds.

the phone storage wont mount ( debugging enabled ) it only charges when connected to the computer.

The phone will only shut down if you shut it down while its connected to the charger.

If debugging is off connecting the phone to the computer shows " MTP connected " but it will not show up in the computer.( or connect to kies )

The phone randomly beeps as if the charger is pluged in/out.

Occasionally the phone shows a yellow triangle with a flashing battery on startup.

The battery information/health/status shows " Overvoltage "

what iv tried:

different roms stock custom

root/unroot

a new battery

a new cable

leaving the phone off over night with battery out ( seems to fix the problem for 5 mins or so lol)

Cleaning the USB port

I had this part replaced due to apparent water damage for £27, shipped to a factory in Glasgow.

Book it in for a repair. I tried everything you did and nothing helped. Booking it in was the only solution.

If it's under warranty send it back for repair.

Mine is not under warranty. I've found that using the Nodock app as noted in an earlier post works 99% of the time. I still get the occasional dock mode coming on maybe 1-5X a day or some days none at all. Prior to this I had all the symptoms everyone is saying aside from the battery overheating issue.
[Galaxy S II Q&A, Help & Troubleshooting] march83:
i ordered several usb boards - 2 of them were rev2.2 which when in easily and solved my problem.

i strongly suggest self-repair if your warranty is void (due to flashing or if the phone is 2nd hand or whatever) and you're at all technically minded - it's a very simple task that only involves removing about 8-10 screws which can be done in about 10 minutes and is very inexpensive.

It is moist on the pcb of the phone. Keep it dry, or but it in rice. And you'll see the issue is gone. Had this issue for 4 days. Now everything is fixed for the last 3 weeks or so.
[Galaxy S II Q&A, Help & Troubleshooting] Andreewww:
Had this problem as well for a few weeks, but it sort of disappeared by itself. Not sure if it has to do with switching to an ICS rom or just keeping the USB port clean.
[Galaxy S II Q&A, Help & Troubleshooting] jakoob_cz:
Same problem

I'm now testing Sensation XE, so my SGS II stayed for a week in a Kidigi dock (with HDMI) and accidently the battery discharged during the time as the plug was switched off.

When I wanted to start the phone even with charger plugged I couldn’t. After removal battery I managed to turn it on, but that yellow triangle appeared. After few removals of battery and turning off and on again, I managed to run into Android and phone started proper charging.

From above I suppose, that the problem is both in software and hardware. But for sure I can eliminate dust inside USB, as the phone stayed connected in dock for whole week. I think the trouble appears, when you totally squeeze the battery.

Maybe I will try to squeeze the battery again, and suitable app for it?

I think with new LPB ICS FW there is one more issue with battery..

Everything was working fine in ICS leaked FW till last night.

But .. Suddenly phones light lit up while charging, i thought it has fully charged. But it was just 67%.

Then this happened few times.

After that i unplugged the phone and started doing something on it. Suddenly Tap to Talk opened automatically and closed.

It happend many times. I rebooted, but it kept on happening.

I switched the phone off, but it turned on itself after some time.

I plugged in the charger, but it dint charge.

I tried USB, same result but a promp, charging pause due to over voltage.

I took out the battery for whole night an d put it on in morning.

Same tap to talk and not charging.

Then flashed back to original stock 2.3.6 and now it seems to be good.

Anyone having same issues.

For ur info i flashed ICS on Friday, and till last night there were no issues and i dint installed anything new.
[Galaxy S II Q&A, Help & Troubleshooting] MadWhips:
I had the same problem. It only started after I installed an ICS rom. I reverted to my previous gingerbread rom and the problem was still there...

It scared the $hit out of me cause it looked like a hardware issue. I then flashed CheckROM RevoHD v4 and now the problem has gone away.

It has now been half a day of no phantom charging issue so I'm going to try the same ICS rom again (Resurrection) and see if it brings the problem back.
[Galaxy S II Q&A, Help & Troubleshooting] markp1989:
I didnt, I tried CM7, stock and the leaked ICS release all had the charging problem.

Amazon got the replacement phone to me the day after the other one was collected so I was only without a phone for just under a day, with exams in early january the phone wasn't being used much so I didn't miss it too much.

I am having the same problem with my phone, it thinks it's always connected to usb. It just started happening when the weather got really cold last week, must have been the condensation some people are talking about.

Anyway it's still bugged after 10 days, I'll send it in for repair, cleaning the port didn't help.

How much did you have to pay if its not covered by warrenty.

Ive also got the saw problem. ive had cpw to flash it but still the same. also how long did it take to repare it.
[Galaxy S II Q&A, Help & Troubleshooting] ewok666:
Same problem here. All good initially on LPH. Then after a few days the phone thought it was connected to a charger when it was not. No moisture of any kind and nothing would fix it.

Flashed back to 2.3.6 and have not had the issue since. Maybe a bug somewhere in the ICS code that makes it overly sensitive.

my 6 month old sg2 has the same problems with going into car mode and not turning off etc.

tried cleaning it. in the end phoned smasung to log a repair (the reseller was not interested as passed 28 days old) and sent to birmingham for repair (inter city i think) and today they phoned me to say water damged just as lot of other people on here and they would not fix it under warranty.

I complained to samsung and there not interested and said they have to take the word of the reapir shopm, theyalso said thery have no record of other problems like this with there customers. based on this forum alone that clearly is very wrong.

And the repair shop want £45 to fix it. and also now my warranty is viod because of the damage unless i pay for it to be repaired then the work will be covered and my warranty will be valid again. this is a joke.

Which car phone wharehouse shop is fixing the phones? as i have asked for a second opion.

Maybe i should just pay the £45. or change the flex cable myself for £6 and then have no warranty which is practiclly useless anyway. just sounds a little dauting to change this.

my nearest cpw repair shop is coventry about 15 miles away.
[Galaxy S II Q&A, Help & Troubleshooting] chrisjcks:
This happened to my SGS2, i sent it in for repair.

It also wouldn't let me turn off the phone, it would turn itself back on.

Faulty USB slot, probably dirty but I tried cleaning mine & it didn't help it.

This was before I was aware of mobile odin, i was worried sending it in as it was rooted, with villainrom installed - but they still fixed it. :)

Although, my screen is definitely a different one - the auto brightness is alot darker on this one, but no big deal.

I believe they replaced the guts of it all.
[Galaxy S II Q&A, Help & Troubleshooting] gezscott:
well i payed for my phone to be fixed. and got it back today and they have replaced the USB board and it seems ok now.

Even though i paid the would not give me back the old part as i wanted to see it and said it had to go back to samsung.

Aslo after i agreed to reluctantly pay they pahoned me back for the unlock code of the phone. so that was the first time the tried to turn it on. makes you wonder if they looked at the usb board at all as i gave thme so much info about the problem. and they most likley knew what it was with out looking and gave me a deafult response of water damage.

cleaned miniUSB port with a staple

I also got this problem suddenly... a few days after I flashed a new ROM and and a night of intense Tower Defence.

I was worried that I broke something because I gamed while charging...

After reading this thread I cleaned out the miniUSB port (had some dust in it) thoroughly with a bend staple and the problem dissappeared.

any advice???

[Galaxy S II Q&A, Help & Troubleshooting] benlc:
Same problem here. I've been reading a bit about it on internet but it looks like it starts generalizing a lot (good job Samsung !).

First of all, it's no software issue. Yes, changing rom might make the issue "disappear" for a day or two, but it is not a fix. The first advice that fixed the issue for some people was to clean the port with a qtip and alcohol (very little alcohol, don't dip your qtip in your bottle of 90% alcohol and then put it on your device).

Just take of the battery, put a bit of alcohol on the qtip to make it humid and try to clean gently as much as you can the inside of the port. Let it dry (the guy who suggested that advised to let it dry 24 hours, but I think 12 would be safe enough).

That should fix the issue for a while for some of us, but you should also get a replacement port on ebay for when it breaks for real (because I'm sure it's gonna).

Good luck

ok i've checked

i made upgrade from 2.3.3 to 2.3.4 and all this mess begin!!!!

now the mobile have been charging all night

BUT now it look like the battery is going down faster but now sure..i will investigate

I AM SURE IS A SOFTWARE PROBLEM F....K SAMSUNG

now i plugged the charger it looks like is charging

but one hour ago it was charging and then for some reason stopped as it charged only 2%

this last issue make thinking is a hardware connection problem something like how the plug is positioned (ok sorry for my bad english)

saty tuned

Got exactly the same problem here in NZ.... Car mode keeps activating, then voice recognition software, phone thinks its charging with nothing plugged in etc etc.

My phone is connected to the Telecom XT network and is only 4 months old. Just sent it away for repair with their service agents Telelogistics and they've come back that its water damaged and therefore not covered under warranty and want me to pay $115 to fix it (which I understand includes replacing the faulty USB port). Not only that, they now say the warranty is completely void due to water damage.

Has anyone had any success in dealing with Telecom in NZ? Or managed to get Samsung to acknowledge that there is in fact a hardware fault on these phones?

[Galaxy S II Q&A, Help & Troubleshooting] RFC1795:
Same problem

I developed the same problem after a drop of water splashed onto the phone near the USB charging port. Left to dry, tried cleaning it, reset to factory default.

So now I have ordered the part from a UK ebay seller fasttracksss for £6.99 delivered. (rev2.2)

Think I'll rather take a chance repairing it myself than potentially get back some other 2nd hand phone or screen scratches etc (has happened at times from people sending in.)

I was thinking I'd try under warranty, but I suspect they will go the water damage route like with others too.

There is any possibility to delete the message "Charging Pause. High Voltage" with root explorer on android 4.0 official?

[Galaxy S II Q&A, Help & Troubleshooting] woolhead:
Been having this problem for a week now. Started with the phone taking a while to recognize the charger and showing it was charging for a few minutes after unplugged. Then this morning after an hour or so of being unplugged it went into MTP mode. So turned off and went straight into charging mode with the temperature screen flashing. I was rooted (stock orange rom and kernal) and reflashed the firmware with Odin to remove root and reinstall any deleted orange apps (was expecting to have to send off for repair, also ordered a jig) turned back on after flash and the problem seems to be gone! So not going to root for a while and see how things go. Glad to see its not just me having the problems though!
[Galaxy S II Q&A, Help & Troubleshooting] RFC1795:
Doubt its the root causing your problems based on much evidence above and other places. Might have got lucky with the port being dried and a kick to the system ;) ... many have rooted, my other that is rooted also which I got the same day has no issues .. and fact I spilt a drop of water near the port indicates a problem like others have.

My part arrived super quick .. going to have the wife attempt the repair job later. Fingers crossed :D
[Galaxy S II Q&A, Help & Troubleshooting] bandzo87:
Hello everyone. I have all these problems with my sgs and I "founded a solution":

Car mode activating at start, charging automaticly stops, it display charging without a charger at all and etc... So I googled for a while and founded a solution.

The problem is NOT IN SOFTWARE BUT HARDWARE (The USB port is diry). I tried cleaning it with smal brush but that helped just for a half a day, so i decided to open my phone and completely clean usb port. When i opened phone i founded limescale covering usb contacts on the board. So I used a litle brush again with destilled water and slowly cleanned port, and to be sure I used a thin needle to separate usb contacts and be sure there is no dirt or limescale between them anymore. After that i fill in the holes on usb with smale peace of tape so dirt or water can not get into the phone anymore.

At the end i assembled the phone and guess what :) my phone is now charging without any problem, Car mode activation gone and all other charging or USB errors. Also for those of you who have problems with the upgrade to ICS or any kind of problems in Odin (especialy when Odin stuck on "setup connection"). I have that errors 5 days before cleaning and after that problem gone, I successifuly upgraded my phone without error. Sorry for my bad eng and I think this will be helpful for you too.

Hi Eveyone...This forum is really good and trustable for android phones and smart phones.

I have samsung galaxy s2 i9100...And as you see i have this f**n usb port prorblem...I found this topic in this forum and i ordered this part for i9100 from tvc-mall. Before that i cleaned the port with anti-oxide syprey and brus several times.But nothing happend.I ordered two piece and it takes 25days to Turkey.Anyway everthing was ok at this point...

After open the box i saw that parts were different. I mean I took off from my phone and every tree part were difeerent.Also they have different code like R84 or B62 etc.Three of them are rev 2.2.And also one of new one hasnt got mic on it:)I installed the right one which has got mic.Olaaaa.The usb port problem is gone!!Not anymore getting charging itself or not anymore getting car mode itself or not anymore mtp error itself...But now i have another problem :(:mad:

I have no GSM signal. After changed the part first i coulnt recognized this problem.Then i decided to intall old one.And thats it !Yeah usb port problem was back again but GSM signal was very good.But when i install new one GSM signal is really week:(

When i look at the parts carefully there were some missing components on the new one that some resistors or diodes which are besides antena plug and which are up the two pice of yellow metal:(((

Now again i cant use my phone :(No GSM signal:((I dont have waranty coz i bought this phone from England.

Now im asking you guys who has changed this f**n usb dock board.Which site or which seller you bought from without any problem.Or do you know any solition about this?Its obious that its coz this part...

Pls and im begging you :) as i said let me know the solition or where can i buy new one witout any problem.Thk you all and good day my friends.
[Galaxy S II Q&A, Help & Troubleshooting] RFC1795:
My first thoughts are, you may not have connected the aerial properly.. the thin braided type wire running down the left to bottom left of the USB board.

I got my board the day after I ordered it from UK ebay seller fasttracksss for £6.99 delivered. (rev2.2) ... I went with this one as it was most local and only one advertised as rev2.2 that I could find.

Hi,

I also had the same problems with this issue as most fo the people here, as i explained in earlier posts.

I thought the problem was with the hardware, but it's defnitely not.

Since i installed ICS (around 2 months ago) all the problems were gone. I could charge perfectly (the system would directly detect the usb charger) and i've never again got the Spurious battery screen.

---------- Post added at 03:01 PM ---------- Previous post was at 02:59 PM ----------

Sorry i forgot to mention before.

The first ICS rom i got was Andyx ROM. And now i have Spike's Pure ICS 7.1 (i had 6.0 Special edition before). With all 3 roms i've never had any problem with the usb charging port and the battery. I had them with Gingerbread official 2.3.4

I had tried everything, from cleaning the port with air compressors to a toothbrush as many suggested, but at least for me it was definitely NOT a hardware problem, but some bug with Gingerbread.
[Galaxy S II Q&A, Help & Troubleshooting] RFC1795:
I think you may have got lucky in that the part dried or sorted itself enough like with others who had waited and who'd done the cleaning bit.

I spilt water on my phone, problem occurred as described by many others. I have two S2 phones, both bought the same time, running same software, no problems as yet on one.

I replaced the part, the problem went away .. if it was definitely a software issue it would be a lot more rife out there and the problem would still have been there after I'd replaced the part ... Think about it. This is not a software issue.
[Galaxy S II Q&A, Help & Troubleshooting] Benfran:
Well, that's why i said i think it's a software problem, at least for me.

Don't you fins it strange that 1 day before installing an ICS rom i still got the problem, and then it simply disapeared after ICS?

You think it magically dried or fixed itself during the update ??

Anyway, i just wanted to explain what hapenned to me, as i tried all the methods i found hardware-wise and none was working.
[Galaxy S II Q&A, Help & Troubleshooting] RFC1795:
Thanks for mentioning it anyway, the more that share their experiences the better it helps diagnose issues and provide possible other solutions ;)

I tried a factory reset, clearing cache etc from recovery. Which didn't help. I figured as stock ICS was released I could try connect to Kies to see if it was ready and would make a difference.

Problem for me tho was, as debugging was ticked on, I couldn't untick it as it kept saying I should remove the USB cable first (which is was of course) - Doh! ... So I decided to wait for the part rather than going the Odin flashing route.

:D
