I can't seem to find anyone which has exactly the same problem as this although a few similar posts.
I think my USB connection may have got a bit moist in the snow lately. I got a message saying unable to charge by USB when it wasn't even plugged in. Plugged it in PC overnight to charge and when I unplugged it the charging symbol stayed on.
I can't boot the phone up as it constantly loops on charging/not charging and can't boot into recovery. I can boot into download mode but nothing shows as connected in Windows despite reinstalling drivers several times and trying another PC.
It did start up once yesterday but having powered it up again since after leaving it to dry out it seems it was a one off. I've ordered a replacement charging port module which I'll try once it arrives but wondered if anyone has any advice in the meantime?
Some threads have mentioned not being able to turn the phone off but I can't even turn mine on! Although I guess I can't turn it off either since it is constantly restarting the battery icon when the battery is in. I've tried plugging it into the wall and PC, it does charge to 100% but still can't turn it on.
does sound like it is water damaged, it also sounds more likely that its not going to be just the charging port
try using JIG and removing the battery... it may help

Well once I managed to boot into it yesterday it worked perfectly, so pretty sure everything else is working fine it just has a problem constantly charging and disconnecting which is stopping it booting properly.

Thanks. Will try tomorrow with the JIG and new board when they turn up. The thought of having a £300 paper weight sickens me!
Fixed it temporarily at least.
Unscrewed the 7 screws behind the battery cover. Disconnected the usb/charging board from the mainboard. Turned it on and it started up then plugged the usb/charging board back in and restarted. All works great now except it still thinks its charging and not charging repeatedly so won't go into a deep sleep but that'll be fixed once the new board arrives.
I am having this exact same issue. My damned ski pant pocket decided to open up a bit and let some powder in. Not much snow got in, but enough to cause some issues apparently. I cleaned the USB port with rubbing alcohol and same with the contacts for the battery. It seems to have stopped, but every once and a while it will try to go into car mode. Kind of frustrating.
Yeah, it still thinks it is charging after I unplug it, and sometimes it will not recognize that I am charging when I do plug it in. Any ideas?
I have the same problem... Started with going into car mode... then telling me that the usb is plugged in when it isn't. Now says it's charging all the time and when I reboot that the battery is overheating... Can't restart unless I go into cwm and reboot. I've got a new usb port/board on order and hope that fixes it.

Can you point me in the direction of one of those? I think I may need to pick one up.
I just plugged my phone into my computer to charge it, and my computer failed to recognize it. I think the issue must lie with the usb port on my phone, as there is absolutely nothing else wrong with it other than the charging issues.
I found the usb port/board on ebay... Search for usb flex cable or charging port. Think it was less than 20 bucks, just hope it fixes the problem.

Thanks, me too. Just ordered one. I picked up a new battery too, because mine was having issues.
The new usb board fixed my phone...yay!

Sweet, did you happen to check the revision number on it? I bet it was fairly easy to install as well?
Didn't check the revision number...
Wasn't that hard to replace. The board and flex cable is glued to the housing so I had to carefully lift it off after unscrewing the two screws. There was another screw on the motherboard that I had to take out... and then lift it up a bit to get the cable Unglued and out.

Yeah, that is what the video I found seemed to indicate. Ha, I work on laptops and desktops on a daily basis, but I still get nervous about small work like that.
Update: I just installed it, and it fixed my issues regarding charging! The battery is still being retarded, but I have another than is on the way.

I have a similar problem.
No matter what charger I use, the phone randomly switches between charging and non-charging state.
Is this a problem with software or the port.
Just to clarify, I can hold the phone upside down, hanging from the charging cable, or wiggle the charger and it will continue to charge. The above error is just random. This leads me to believe it is a software or battery problem.
well after flashing back to o2 ke7 all is well again so must of been software related

This happens to mine too. I'm on the stock unbranded firmware and haven't rooted our updated. This problem randomly appeared about a month ago.
I've just started seeing this problem now in the past few days.
When I unplug the charger, either the battery charging icon stays on, or the "Battery full, unplug charger" notification stays there.
The big problem is if I turn off the phone. After shutdown, the screen stays on showing two different icons (changes between them every few seconds). One icon is a battery half full or so, the other is an empty battery with a yellow triangle and a icon of a thermometer next to it.
When this happens, I can't turn on the phone. The only way I can turn on the phone when this happens is to plug in the charger, start up, then remove the charger again.
I'm on rooted KG2, XWKDD kernel. Bit worried about this, I'll try another ROM & kernel but I don't think it's software related?

Galaxy s2 car mode and charging port issue - resolved
HI,
I have been facing this issue with my galaxy s2.(When i have created samsung account and install Darky ROM 2 - XXKH3 ROM)
Issue:
1)Activation of CARD mode - automatically.
2)Charging automatically- though charger is not connected
3)Enabling the voice mode - automatically.
4)Battery draining problem.
5)auto handsfree speaker enabling
Solution:
There are two solution for the above problems:
1)Assume its not related to hardware (My case), i have wipe all the data(Using Darky Rom 2 tool), problem seems to occur even then.
I have updated the ROM to XXKG3_ODEXED. - that totally solved the problem.
I m using my S2 now for a week...no issue.
2)Assume its related to Hardware issue, (in some case's), you can clean the charging port by using thinner( nail polish remover - easy to get and cheap).
First u have to remove the battery, (preferably in direct sun light), use cotton to soak thinner, apply it on inner side of the port. keep the phone as it is for 20 minutes.(30 would be great).
Insert the battery, power on the phone.....problem solved.
I have tested it on 2 S2's, one with software problem and one with hardware issue.
Hope that will help....

Hello, i had the similar error. I had to send the phone to Samsung. Let see what happens....
same problem here..100 % same issue...what to do...this is pathetic
Same problem here, just after a month of having the phone started the problems. The five problems darshangkolhe said, but also: auto power-on of the phone when I switch it off, and what it is more annoying, it is very difficult to get detected by Kies when it is plugged to the PC. Sometimes it only starts charging and others nothing, not even charging the phone.
I am very dissapointed with Samsung, I have paid 500€ for what was supposed to be one of the best phones, but just after a month of use it is going crazy!!
I am bringing it to the Samsung´s technical support this week.
Take a toothbrush and brush the Micro-USB port vigorously. Fixed.
Having the same problem, fixed doing the above. This phone was awesome. But it just looks so much like its a big rush job with all the bugs that were there. The screen coloring. Now the USB-port.
Meh.. wondering about that 5 phone..
Thanks prodygee, but I´ve already tried with a cotton bud with a bit of alcohol and no luck. I will try to get my phone fixed by the technical support or replaced.
I can not think about the 5 phone, I have spent 500€ not even 2 months ago, so for me another phone is not affordable.
I just want my Galaxy S2 to work as expected, it is not a low-cost mobile!
mine has been fine since, but today it has started doing it again so its booked in for repair at CPW,technician states he has all the parts so will do it while i wait
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
What's the deal? Does anyone know how to fix this problem?
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 .
jje
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.

I recorded the problem.

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

First Phone show Battery and triangle with temp and when booting phone is in KIES mode like is pluget in after reading of billions of forums i found that can be because of Sand,water etc on usb port, what i did i take a Air compressor and i clean a usb port via Air compressor and now phone refuse to shutdown only reboot but i can use a Usb debug Kies Maybe we have to try solding a Usb port !!!!
Here is a FIX

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

Hi all,
I have an AT&T Samsung Galaxy S 2 (i777). It was rooted and running CM 10.1. A few months ago it started to have charging/USB port issues. Some of the symptoms:
-Sporadic charging (starting and stopping)
-Required USB jiggling to get it to start charging
-Sometimes wouldn't charge at all until it died, then would eventually charge while powered off
-Would not shutdown (only reboot, even if the battery was removed)
-Randomly started "car mode"
My initial thoughts on this were USB port issues. After doing some research on people with similar problems, I tried cleaning the port with alcohol, toothbrush, compressed air, etc. No avail.
Eventually the phone just stopped charging altogether. At this point, if I left it plugged in, it would sit in a continuous boot loop (boot, get to lock screen, realize it has no juice, shutdown, rinse, repeat). After a few days of attempting to charge and just having that happen, it went black and has never turned on since.
To try to solve that, I bought a new USB port flex cable on eBay and replaced it, assuming this would solve all my USB port issues. I tried to be as ESD safe as possible and also not break anything in the phone, but after replacing the board, it still wouldn't boot.
Next step- bought a new battery with an external charger to skip the USB port altogether and see if the battery was shot. Charged up the new battery, popped it in, nothing.
I'm at a total loss. If it started as a charging problem, I don't see how the problem could have been anywhere but the flex cable board or the battery. Does anyone have any ideas about what might be going wrong? I would REALLY appreciate some insight.
Thanks!
Maybe the repeated loops damage it

Did you ever find a solution? I'm in the no charge boot loop after letting it die last night.
I have not seen previous usb problems at all. I suspect that my battery got over-drained, but then I've got the same symptoms as you and you have a new battery. I can get it into recovery but t won't stay on in CWM for long enough to fix permissions, which is the only thing I've tried so far in CWM.
Thanks
If i was in your place i'd have taken it to the nearest Samsung Service center and let them fix it for me.
I think the fluctuation in power may have damaged your phone battery point from where it takes power from the battery and charge it.
Maybe it has damaged the motherboard.
We cannot say anything in this situation.
You should just take it to your nearest service center.
Best of Luck
OK, wiping Data fixed it.
Thanks for your reply. This problem just started this morning with no previous issues, doing the looping part of your problem that I quoted. so it's not a question of what I might have done.
But, for others encountering my part of it, here's what I've done and learned so far today.
As I looked into things elsewhere on the , it seemed to be a software problem. Luckily, I have another Galaxy (Exhibit) that's similar battery and I was able to put the charged battery from it into the SII. The SII booted and worked fine but did not charge. I put the SII battery into the Exhibit (sorta fits). It took a charge.
This confirmed to me that it's not the battery. It must be the phone perhaps USB port or more likely "firmware" since problem started abruptly after draining battery down.
I then wiped data on the SII from CWM/recovery and rebooted.
SII is now charging again. Stock battery is back in and working.
Time will tell if all is well, but here's what I think happened:
1) battery drained down to zero while unplugged
2) plugging in and starting up phone immediately threw something off in the battery stats at a low level...that kept it from charging even when turned off. Or rather threw it into a loop. Don't really understand this stuff, but may have to do with physical things that happen in a battery when the cells drop down way low and then the voltage feedback they give to charging circuit.
3) charging battery in another device (gingerbread, by the way) got the battery out of this, if battery had been a contributing factor,(or just a trigger) it was back over the hump.
4) wiping data fixed the charging, so I conclude it was a charging circuit data issue triggered by an ultra low battery.
Hope I'm over this problem and hope that it helps somebody else. If you run into this yourself with no previous USB or hardware issues, I'd suspect software before hardware. If I had only one battery and no way to charge it externally, I would suggest get one of those simple universal clip-on chargers to bring the battery back up and then go into CWM and wipe data.
UPDATE: It's stopped charging again. It's no longer looping since I got the battery charged up, but not right either. As soon as I plug it into a USB, it boots itself without powering on.
I guess that this is looking more like a physical USB issue now. Weird that there's been no previous sign of trouble before today.
UPDATE2: I cleaned USB port but no help. Then I bent the USB contacts towards the screen and it is charging now again. I'm ordering a replacement USB.
I should add that I'm running Shostock Jellybean, older (not current) version with it's associated Jeboo kernel. Don't know if it matters.
I wish I'd seen your post sooner.. I had exactly the same problems back in January. Took all the same steps you did. In the end, an 8$ USB flex cable from EBay solved the problem. I think you'll have luck with that:thumbup:

hey, I'm experiencing the same issue slightly different.
-Sporadic charging (starting and stopping)
-Randomly started "car mode"
-plugged in the charger while the device is switched off, it automatically turns the device on.
-If the cable still plugged in while the charger removed from the main current, it shows "Charging stopped. High voltage"
-From yesterday, it doesn't charge even. Only way to charge is, connect the charger first and then Restart the device.
Then only charging continuous.
Can anyone help to solve this? Is this a software issue?
Thanks!

Also, there was this issue early --> when I charge it from the laptop, the USB mode doesn't switch on. It just charge the phone only.
But now it's not even working like that.

hi, my s2 wont charge. It just shows up charging when plugged in but it doesnt charge at all. and it overheats too much while plugged in. What is that flex cable you said, is it the one that connects the charging port to the motherboard? were you the one opened and replaced it? thanks
Hey guys, it's been awhile since I asked a question, but here I am, lol.
In a nutshell, I'm pretty sure something in my device (hardware) is fried, but I thought I'd see if anyone knows better.
The problem is my device seems to be sending power out of the usb port, and doesn't connect to the pc or recognize it is charging correctly.
This also applies to download mode (windows says device has malfunctioned) and when powered off (there is no battery that shows up when plugged in). In order to power back on after turning it off, I have to remove the battery, then reinsert it while holding down the power. I can't think of much that could have caused this, other than I was visiting places with high humidity levels. One unusual thing that happened before this started was my device rebooted into safe mode when playing bad piggies. That was really weird since I have tried booting into safe mode before, but thought samsung must have disabled it for some reason. I have already tried wiping data and flashing a new kernel/rom. Obviously I can't re-partition since I can't connect to my computer in download mode. What do you guys think? I think it is time for a new device.
EDIT: I should mention that it started behaving normally yesterday for about 5 minutes, but then it went back to this.

I'm 99.9% sure that under normal conditions that an Android device should never power the USB port. Source of speculation. If it is indeed powering the USB, then you've either got a really wonky firmware installed, or some sort of hardware issue. I'd try to make sure that it's sending power out before going further (especially if you can't charge it, the battery will be dead soon). After this test, I'd keep the battery out for a while, just to be sure it's not going to short anything.
One thing I've noticed in my tinkering is that taking a device apart, then putting it back together again can mysteriously fix problems (although 75% of the time the fix is temporary). If you suspect water damage, opening it up and letting it air out might help. I want to say there are certain cleaners that are great for cleaning up any water spots that might be shorting things out, but I've never had to try myself.
That's all I can think of right off. Good luck.

Yeah, I'm working on taking it apart right now. With my limited experience on electronics, I would be willing to bet it's a capacitor that's gone bad somewhere. That wouldn't be a problem on a desktop since I could just solder a new one in, but I don't think I have the skill to do something in such a small scale, not to mention I don't think you can even buy them that small.
The same thing happened to me, and I had to send it in for repair. Luckily, I was still in warranty. Also, are you sure it's not the charger cord?

I've tried multiple cables, and I'm unfortunately out of warranty.
Upon disassembling and cleaning with rubbing alcohol, it seemed to be working properly, with the exception of computer connection. However, I plugged it into a DC car charger (leaving the charger itself unplugged from an outlet), and the light came on again (which is what I was talking about when I said it was sending power out), and now it is acting weird again. I guess I'll take it apart and clean it again...

honestly, i cannot begin to fathom what could be causing this. it seems to me samsing paid more attention to the charging port then say amazon did on the first gen kindle.
i do however, wish you the best of luck and hope you somehow manage to fix it

See! Told you taking it apart and putting it back together again works... temporarily. :silly:
You're right, that does sound like power going out. Which would be super cool for powering, say, a micro USB laser pointer, but it's not so great when it should be charging. Can you double check with another device that the charger doesn't light up normally? I know my wife's laptop charger has a LED that stays on for a long time after it's been unplugged from the wall, sipping off of power left in the charger. It could be something similar with your charger.
Just a though... if power is only suppose to go into the device, then wouldn't it be reasonable to assume to that there would be a diode forcing power to only go one way? Or does it need to cycle power back to the charger? IDK, but it might be worth looking to see if something looks missing.
I read somewhere that if the battery voltage gets too low i.e. battery is totally flat, a current will flow from the device to the charger so this may be what's going on here. I didn't really understand the post as I was just whizzing through the thread, but i think the solution was to charge the device for many hours until the battery voltage was high enough for normal charging to occur. I'll try and locate the post, but it might take a while

@iJimaniac if all of these suggestions dont work, there is the possibility to just buy another battery and a battery charger and keep switching out the batteries when they die
Maybe @henk5066 would know something about this?
From what it sounds like, your power circuit is fried and is not directing power correctly this means that you're probably going to have to replace the mainboard. however don't worry. you can get one from a player with a broken screen on ebay for about 10 $. I can p.m. you some links to products on eBay with main board working and not screen and I can post a video on YouTube that shows you how to replace the board. it's actually rather quite easy. I don't get why most people don't do that and instead buy a new one. let me know if that helps

Wow, I didn't realize a broken player is so cheap. I'll look into it, and instructions won't be needed; I've already fully dissasembled my device many times in the past, just for kicks.
Edit: could you send me those links? I'm having a hard time finding very many under $25, which is still a good price I suppose.
the broken player it's self is cheap (0.99$ if your lowest bidder and win) it is shipping that makes up for most of the cost. Just make sure you get one that says powers on, that is the main indicator that the main board is still good.
EDIT: I just looked on ebay, aparantly the person i bought my new board is out of the 4.0 player. and it looks like there is however one with a 9.99$ bid. you could raise it and get the player but that is the cheapest you will get. i will pm you a link to it.
I had the same problem
I had the same problem, what i did was, instead of charging it with the original charger, i charged it with my nexus 10 charger in download mode all through the night, and the next day it would have about 80 percent charge and it was in the system, but it drained quick when i would unplugged it, so i repeat the same procedure over several days until get to 100% and scince then i have had no problems with my SGP, hopefully i helped you

Interesting, i thought the devices could not charge in download mode.
On the subject of odd charging behavieor, has anyone noticed that when plugged in running cyanogenmod overclocked to 1200mhz, the micro usb port area on the player gets rather hot?

I haven't noticed excessive heat in that area.

As of last night, whenever I try to connect my phone to either my outlet charger, my xbox, my computer...anything, it never even charges. The icon on the screen still says, "Connect your charger" even if it's connected. The sound doesn't even come on, and the battery icon doesn't move when it's connected (obviously, because it's not charging lol). But the only way I can use my phone is by charging my battery first. (Luckily I had a spare battery that I had already charged) and now I'm looking to buy a battery charger so I can switch battery's whenever I want. It'll be a pain in the a**, so there must be a way to fix it. Sometimes when I disconnect my charger, the icon pops up saying, "USB Connected". I've tried 4 different chargers also, and still no luck. I still haven't bought my warranty so I don't know if I can still do that and exchange it.
Any suggestions? I already tried different battery's, removing the battery for a couple of minutes, charging the phone while it's off (it seems to work but the battery icon goes from 1/4, 1/2, 3/4, and to full, then back to empty, and it does it again, but it freezes and it takes awhile and then finally it does it again, but it doesn't really charge.)
My phone IS rooted, and I have ShoStock3 with Clockwork Mod. I'm thinking of reverting back to my Clockwork Backup from March but I don't think that'll work. I don't want to loose anything from my Internal Storage that I may have stored.
Please help
May be a bad usb port or could be dirty..

Is there any way I could fix it? And is there anyway I could clean it if it's dirty?
By the way, what's that charging port USB Dock Connector for? I've never seen them before so I dont know what they're for or how to use it.
Edit: Nevermind, I did my research and found out what it's for lol. I don't think I'll want to go that route, I hate taking apart computer's or phones because I'm not good at following instructions and I sometimes loose the parts lol.
This has happened to me three times. It's the charging module. You have to get it repaired I'm sad to say.
