So i've had some battery issues for quite a while now, on every single rom. These were mainly that the phone always seemed to think it was charging, but the battery "value" dropped. Battery also lasted half a day or so, even with Apolo regular. Lastly, from time to time, after resetting it, the phone would be at around 14% and start increasing every five minutes or so. So i just dealt with all that for a while, noticing that usb almost never worked and it would take the phone a bit to realize it was actually charging (it wasn't always "passively charging").
So the other day, i turned it off due to low battery, just saving some time later. Then i see the battery "loading" icon, then a green battery 3/4 full with the 5 dots in the bottom, it would get to the third one, then vibrate and turn off. I tried turning it on only to see the S II splash and having the phone turn off instantly. I also tried turning it on while charging, no luck. So finally, i tried google, and found this. I did it with a paper clip and a toothpick, it seems to be separated but there is a tiny bit of dust i believe. Well this did nothing for me and now i'm desperate to fix this battery problem that i have. And pretty sure i can't return the phone cause i violated the warranty.

My wife's S2 had pretty much these same symptoms. I replaced the USB board and everything went back to normal. I wrote a guide on how to do it.....

It's quick, easy to do and inexpensive to buy the part (compared to what a service centre would charge you).

Hmm...
Seems kind of a desperate means, isn't there a way i can do that without replacing it?
You got the best possible advice & a simple/cheap (guaranteed) fix from the person who is the expert on this sort of problem with this phone & you're questioning it ?
*shrugs*
Your phone stays like that then.
You *might* get a temporary fix by playing around with the contacts within the port.....but even if it works, it will ONLY BE TEMPORARY......
The Samsung service centres will certainly NOT faff around and desolder/resolder a new port to the board.....they'll just replace the entire board.
It's not like you are replacing the entire motherboard because on the S2 (unlike on some phones) the USB board and the motherboard are separate........

it happens when your charging port is having a short connection. perhaps u'd need to change the charging port. if your device is shorted or not, it can be tested. if you have a multi-meter, you can easily test it.

It wasn't meant as disrespect, just that ordering this kind of stuff down here in Chile is not easy or cheap, so if there was any other solution i'd prefer it.

That's the problem for me though... No Samsung services here in chile. Any way i can return it is with my service provider, which will probably see the triangle and blame this on that.

ruh roh. Did this behavior just start on its own randomly? Sounds very similar to what mine was doing due to a failed USB port. I think there is at least one, maybe a couple more, other users on the forums here who also experienced USB port hardware failure. ended up doing a warranty replacement for mine.

While I certainly can't argue that covering the USB port is a bad thing, I carried an HTC aria (same port location, same type of case, same pocket) in a construction environment for more than a year with no USB port problems. While it certainly could be caused by lack of protection (pocket lint was my first thought when mine happened) I suspect a bad batch of Ports made it into the assembly line, due to the number of reports I've seen here. My bad one was purchased on launch day - anyone else have one go bad on a significantly more recent purchase?

Mine was doing the same thing, as well as going into "car mode" randomly and freezing up completely. I found a thread that suggested swabbing out the port with rubbing alcohol and a small paint brush. I did that and it cured the problem, but I also bought a case that covers the usb port (otterbox).
This all went down about three weeks ago and it hasn't happened since.

Got my first one on black Friday, second one two weeks later, third one, a week or so after that. First two were a 1108, and 1110 builds from what I recall. Not sure what my latest build is, but I got this one at a different best buy (first two from the same best buy) so hopefully if it was a bad batch it won't happen to me with this new one. Knock on wood. This time I got best buy insurance. Seems good, $9.99 a month, no copay for replacement.

same usb problems
I am having some of the same problems. My phone thinks it is always charging, the fully charged notification is almost always up, and my computer cannot recognize the phone. I would send my phone in for a replacement, however the water indicator sticker is red (it got slightly wet).
Does anyone have any idea on what to do. Has anyone else had the rubbing alcohol method work?
I just went through this same issue, but I managed to fix mine on my own. I don't have the phone insurance through ATT, and the overseas warranty support center did everything that they could to deny service. Every time that I would call, they would repeat the steps that we had already been through in troubleshooting. I knew from reading here and other sites that the usb connector, or usb board was my problem. I started out cleaning it with alcohol and that seemed to help a little bit. The ultimate answer was to bend the pins in the middle of the USB connector in the direction of my screen, just a little bit. I have been three months now with no problem whatsoever. I didn't tell ATT that I did this, but I wanted to get a new phone, thinking that this fix would eventually cause the port to break altogether.
This ordeal was extremely frustrating for me, because I have been into phone hacks/flashing roms since the WinMo days. They tried to tell me on one of the calls that they had pushed an update to my phone that would fix it. I promptly told the lady on the phone that she was full of @#$#, as I knew the phone had obviously not been flashed or updated by her text message. She finally backpedaled and admitted that she was lying. It was hard to deal with this conversation without admitting what I knew about these phones. The sad fact is that at this time, my phone wasn't even rooted yet.
In the end, I did get a new, factory battery out of the deal. These idiots thought that a new battery would resolve the issue, even though I told them exactly what the problem was.
I was really pissed about the service I received. I am over an IT helpdesk for a software company. If any of my employees treated our customers like I was treated, they would be looking for work. I expect that they are just doing their jobs as supportbots, just like ATT wants them to.
I decided that if I ended up having to replace the USB board on my own dime, I was going to fix it, root it, unlock it and fleabay the thing. I was going to use the proceeds to pay the early termination fee and say goodbye to ATT forever.
I know that this was longwinded, but I have been holding this in for a while now. I posted this in one of the earlier threads, but then deleted it, thinking that I might need to reference the thread to show ATT that the USB issue was a known problem.
I don't have this issue, but a friend does. What would one do if this happened while their phone was rooted? How would you get back to stock with a dead port?
I had this issue a few weeks ago. About 100 times a day the phone would chime, thinking it had just been plugged in/unplugged. I cleaned out the USB port very well with rubbing alcohol (used a small paintbrush), as well as the internal battery contacts. I also stopped taking the phone in the bathroom while I showered, thinking that perhaps steam from the shower could be causing the problem. I'm not sure if the alcohol or keeping it out of the bathroom did it, but within a day or two the problem stopped, and hasn't repeated itself for 3 weeks or so.

I had the same issue and I manage to get to stock usingh Mobile odin, I went to the DSC or how ever is spell The repair center for att. and the guy took it tried to fix it but was no good, so he gave me a new one. And as the chatter kept going he said they would still take them even if there rooted becouse Samsung can just restore them back to stock much easier than we can. Maybe he was blowing smoke but sounded kinda true.
he said mine hjad some sort of corrosion on the USB port that made it think it was connected that's why it showed that.
I am currently having the same issue. I have an SGH-S959g, which is Straight Talk/Net 10's S II. I'm posting here because my phone is physically identical to the AT&T S II. At the suggestion of multiple forums, I've tried cleaning it out with rubbing alcohol. I even took apart the phone and cleaned the soldered connections to the logic board. There was virtually no corrosion on any of the port. I tried bending the pins slightly forward as well, because that has helped with other phones (Samsung and otherwise). None of this is solving my problem and, unfortunately, my month-to-month service means I have no option of being sent another phone. Any help would be immensely appreciated (especially if it contains a new idea or two to try).
Thanks in advance.

Had same issue, fixed it with ebay item 270993875674. I can't post links so you will have to search. I bought my S2 in fall of 2011, tried a different board it did not work. The Q&A forum led me to this ebay item to fix it. It's an easy fix, takes maybe 15-20 mins if you are being ultra careful.
It automatically switches on when i inserted the battery and show charging, some times even if usb is not connected it show usb is connected..
please help me
Thank God I was wondering if all the kids had gone to bed for a second. If you are gonna post something like this don't u think u should provide some kind of useful information?

If it was a piece of Army equipment, I'd say hit it with a hammer. Phones don't react well to that maintenance system.
exact same thing happened to me... when a TINY amount of water got in the micro USB port. You're pretty much screwed, if it's water damage. You can either get a replacement or try and fix it, but I don't think you'll get very far if it's water damage.
I'm sure someone is going to flame you about the search button but it sounds like its the USB PCB it cost $7 from eBay, also the service manual can be found online takes less than 30 min to replace

I was change the usb port
phone works fine,
My phone charges but it seems to be thinking it's always charging even when unplugged. I use it to play music at the bar I work at & it kept going in car docking mode which I never use. My battery was almost dead but it fully charged after the night was done. I went to change the battery to see if that was the problem and when I turned it off the battery charging image came up while it was off with nothing plugged in. Now my battery status keeps flashing & changes from regular size to mini size. Has anyone ever experienced this?

Searching goes a long way here my friend. This is a common problem for a lot of people. (I've never experienced it, but many others have). The solution seems to have been cleaning out the mini usb port on the phone with some 91% isopropyl rubbing alcohol and a que tip. Or if that doesn't work it may be a bad usb port.

I guess I'm in the same boat with you. Noticed a couple of days ago the phone stopped making the little chime when you connect/disconnect the charger. Yesterday I took it off the charger and after a couple hours it was down to 40% without me using it. Today, I swapped batteries and had the same problem with the battery icon. One second it shows about 3/4 full, the next it says 100%. Then I couldn't get it to boot, just kept cycling through the battery icon. Got it booted and not only does it say charging when not connected, the USB icon is in the Stat bar saying it is MTP-connected. Guess it is time for warranty.:crying:

I'm on stock, but rooted. If they will give me an S3 I will be very happy. Having seen how many people have had issues with the crappy USB connector on this phone, I may have to insist.
The likely option will be the sky rocket... maybe the oneX. Unfortunately, I don't see them giving out S3's.

Sky rocket yes. I wouldn't say the one x is a downgrade necessarily
At this point I might be ready to get away from Samsung. My SI had to be replaced 3 times. The S2 has had some weird issues, but worked until this started 2 days ago. I had an HTC before (WinMo) that is still working fine today. Maybe I'll have better luck with the 1X seeing how apparently Samsung can't make phones that last.
I got an S2 as a replacement. Not a Skyrocket, so it depends on when you call. Otherwise all they would offer me was the skyrocket or 2 windows phones.

What do you think would be easier, getting the part & fixing it myself or using Odin with a tricky usb port to revert back to stock?

I don't think switching out the part will be too difficult. I have the same exact problem and am planning on switching the port and ribbon sometime in the next couple weeks. I think I've read that the i9100 one works just fine.

I think the problem is actually in the logic board and not just the connector. Even if you fix it the problem will likely reoccur in time. I don't want my phone repaired, even by AT$T, just to have it fail again, but out of warranty next time. I had to have my Captivate replaced 3 times. Maybe it's time to go back to HTC. It sucks, because I love this phone.

Mine started happening after I spilt water on the end of the charging cable and didn't let it dry off completely before plugging it in. Do you still think it would be in the logic board? Then again, it seems like more and more people are getting this problem. And of course, it's just as the warranty is expiring on these phones.

If it's a physical problem with hardware, no software changes can fix it.

Mine had nothing to do with water. I just think the micro USB connector is a poor design for something that has to be plugged and unplugged as often as a smartphone does and in the kind of environment we use them, especially in the car. The logic board is what the connector mounts to. It takes the signals from the connector and relays that information to determine whether the connection is for charging, PC connection or some other I/O function. Over time the process of disconnecting/connecting will weaken the solder joints and/or cause the thin traces in the ribbon cable to possibly short against each other and create the issues we are seeing. That's why the problems can be seen even after the cable is unplugged. Replacing just the connector will likely not solve the problem.
Talked to support. They are sending me another SII (refurbished). They wanted me to do a factory reset and download an update as part of their troubleshooting. I insisted that no software update would fix a hardware problem. *****ed enough to get them to drop it and send me another phone. My phone is rooted stock 2.3.4. Do you lose root with a reset? If I send it in rooted will that cause me trouble with the warranty dept. even though it isn't relevant to what is wrong with the phone?

Nick says they don't check. I dunno. All I know is if they can prove you messed with the phone and voided your warranty you'll get a bill for 400$
The last time I used my S2 was a month ago. After flashing a CM10 nightly via the OTA feature I just let it be.
An hour later my phone it won't turn on. I assumed that the battery had ran out until after my 20th-ish time pressing the power button my face appears on the screen (the boot logo).
Assuming everything was okay I left it for about 5 minutes before realising that the screen hadn't changed at all.
I pulled the battery and tried again, this time nothing happened.
I charged it, nothing happened.
I used a USB jig, nothing happened.
A few days earlier I had undertaken a mission to replace the USB Port which seemed to be successful, however, I felt that perhaps I forgot to reconnect the display or something to the mainboard - so I re-opened it and everything looked alright, I even assumed there was a fault with the power button - it wasn't.
I think there are two possibilities: A broken mainboard or it is hard-bricked.
If it's a broken mainboard I'd probably sell it as a broken phone on eBay but if it's hard-bricked I'd get a jtag and then sell it.
Lastly, I can't get the phone to do anything apart from heat-up when charging in the usual area near the camera.
My question is "may I have some help getting it to work?"

If it's a broken mainboard I'd probably sell it as a broken phone on eBay but if it's hard-bricked I'd get a jtag and then sell it.
Lastly, I can't get the phone to do anything apart from heat-up when charging in the usual area near the camera.
My question is "may I have some help getting it to work?"

What happens if u try to get in download or recovery mode?

So if nothing works also with USB-jig, this is surely a hardware defect and so the only solution is to send it to Samsung if u have any guarantee...
Sorry.

You're going to have to get it a jtag. I had mine done by this guy on ebay: http://www.ebay.com/itm/Unbrick-Sam...157?pt=LH_DefaultDomain_0&hash=item2576e99b95
Good Luck
Haha, I thought about that but then decided against it for the following reasons:
1) rooted, running cm10 and non-stock kernel
2) I'd already sent it in for a repair of the USB port but they rejected it because of the custom software so it's probably blacklisted or something.
3) It is way too obvious a non-qualified person has opened it up and made changes.
4) the colour of the USB port board is bluer than the main board and everything else
5) sticky tape is missing at the bottom right (doesn't make a difference whether its on or off)
Thanks for the tips but they charged my friend £150 for, pretty much, reflashing stock because he was in a boot loop.

Thank you. I was originally going to get a JTAG done and I'll have the money as soon as I sell my PSP but it'd be a waste if I were to find out that the main board was actually at fault. If that were the case I'd sell it and take a bit of money out of the money I'm saving for my computer and buy a second hand S3 which I would then sell for a profit and buy a Nexus 4.
The people I contacted for a JTAG had a good review by a fellow xda member for the same service on the same on the same phone so it'd cost £29.99+postage.

So I have had this I9100 for about a year. Flashed with CM10.1 long ago and been reflashing new nightlies when i see stuff on the github log that address bugs I want fixed. Anyway the other night I put my phone charging, I didnt flash anything that night just a normal day. Next morning phone is dead. Wont charge, wont boot, no recovery no download mode, PC wont detect anything when I connect via USB. Odd thing is that now when the battery is inside the phone it starts heating up like crazy on both sides of the back camera/sim card slot, I guess where the CPU is.
So I searched for people with dead and bricked S2 and didn't find anyone with this problem, then I searched for people with other phones and again no one with this problem.
So I was wondering if USB jig would be able to help me, or JTAG, or if its just the usb board that died since it was while charging and it gives off no signal via USB to a computer and if I changed that it would come back to life.
What do you guys think? Was it the main board or is it just a fried USB board and the phone can't regulate power without it?
Sounds like the USB board, but you never know until someone 'qualified' has a look at it. We've had a lot of similar problems on here over the past two weeks (this week in particular I've seen maybe 5-6).
Doubt a jig or JTAG would be any good given it isn't a firmware type issue by the sound of it.
I guess I'll order a usb board a replace it. If it doesnt work its not expensive anyway. About $10.
I was wondering if there have been a lot of people lately with this problem could it have been one of the nightlies that screwed up power management and fried the board?

Yep if you can get a cheap one 2nd hand it's no great loss if it doesn't work & you end up needing to replace the MB as well. If you need them, I attached the SGS2 service manuals to a post of mine a day or two ago (click on my name & have a look through my posts over the past few days) if you need/want them.
That's an interesting theory. Not being a dev, I'm not up to spec on whether anything at, say, kernel level could cause something like that to happen (In the 18 months I've been here, I've never seen a kernel/firmware pinned down as the cause of something like this), but you wouldn't say it's impossible.
Edit - Here you go, the zip is attached to this post.

Thanks I'll try ordering and replacing it to see if it lives again. Will report back in a few weeks with results.

Did you try the ole toothbrush trick?? Get an old toothbrush and put it into the usb port an go mad. Sometimes a film can be on the terminals of the usb port, which gives you a bad connection.
" Odd thing is that now when the battery is inside the phone it starts heating up like crazy on both sides of the back camera/sim card slot, I guess where the CPU is. "
This doesn't sound good!
Try that toothbrush trick first before buying anything
Also did you try another galaxy 2 battery? Your battery could be dead. Have you got a multimeter handy?

Yep first thing i did was multimeter. Was at 4 volts. I'm going to try the toothbrush thing and report back.
EDIT: The toothbrush didn't solve it.

With the multimeter check is there a voltage coming from the battery. The battery by itself!. Next leave the battery out from your phone and plug in your charger (which is connected to the wall). Put the multimeter across the appropriate terminals of the phone and measure the voltage if any.
Report any voltages values you have

The battery gives off a steady 4.
The phone connected to the wall without battery gives off 1.3 when first connected or the battery removed and then very slowly starts dropping to 0 going slower as it drops. By the appropriate terminals i imagine you mean the ones that connect to the battery wherethe battery has the + and - symbols.

That USB port is working, battery is fine. Next the screen might be dead. First check to see if the backlight is working. Turn on your phone as you would normally shine a light onto the screen and see if you can see anything. Use a flashlight or something with a high focused beam

If it was the screen my phone would still vibrate at the end of bootup right?
Sent from my GT-I9300 using xda app-developers app
Bootloop is....well....a loop....a never ending cycle. ...if your phone is in bootloop it won't get far enough into the startup process to be able to vibrate. .....

Keith is right. Also not all phones vibrate on bootup, depending on rom and kernel.
Did you check to see if you can see anything on your screen using a light?

My phone did. But i tried the flash light anyway. Nothing on the screen.

That vibration normally only happens towards the end of a successful boot....so if you've felt that vibration, the chances are that you don't have a bootloop. .....the phone would *appear* to be starting normally. But if you can't see anything on the screen, your problems will lie elsewhere.....

So batery and usb charging normal. No screen problems, and heating cpu while off. Most likely main board fried? I'm gonna get some resistors to make a jig and try that anyway. Do you guys thinks 330k ohm will work too? I know its 300k ohm buthave some resistors around that add up to 330 and i wouldnt need to go buy more tomorrow.

Yeah...that CPU heating is a worry.....it's obviously being forced to do something that it wasn't intended to do....and it doesn't like it.....
And with regards to changing the impedance of the jig....probably not advisable. ....micro electronics is very sensitive to resistance and voltage. ...what you're doing with the jig is essentially bridging two connectors. ...
Impedance too low....too much current/voltage passes.....things might begin to get hot (best case)
Impedance too high.....too little current/voltage passes.....no effect.....

Ill buy some resistors tomorow then.
I wad thinking does a normal s2 perform any operation that may involve processing when putting in a batery without turning it on?
I was asking this because it could be some sort of loop in some process it does when detecting a batery.

Well, I'm sure I remember reading *somewhere* that Android phones have a secondary/simplified/low level kernel that runs even when the phone is switched off......apparently that was how some phone on verizon was hacked or something.......
Whether that's true or not....I don't know....
If it is....it could fit in with what you're suggesting....
