So I know there are several threads on this, some by me, but this time the issue is very weird.
So i'm on my third phone now, previous 2 had the USB port going wacky. Phone thinking it was charging when it wasn't plugged in, computer not recognizing phone anymore etc.
So problem has now started again on phone number three. Weird thing is this time the phone seems to not have this problem all day. Problem starts at night, so i'm assuming maybe a battery percentage left triggers it. The other weird aspect of this is that right before the phone starts bugging out, (charging, uncharging, and back, over and over while not plugged in), the car mode symbol appears in the status bar, and starts flashing on and off. If I am fast enough to catch it,I can deactivate car mode. When all this starts happening, phone also starts to get stuck and freezes up. This issue is really getting annoying. Love this phone but this is starting to make me crazy. Yes I got the phones at different stores. What do I uninstall to just get rid of car mode, considering I never use it?

So, instead of using your existing thread, you decided to start yet another one for the same issue? And people wonder why the search doesn't work like it should.
good old miami son taking time out of his non existent life to not give any helpful info, but just to be a wanna be moderator. You were obnoxious and annoying in the captivate forums and I see you picked right up over here. Boy am I excited you got a new phone. Anyone else have any helpful advice?

Seems to be whatever USB cable you are using or the way you carry this phone is the problem. No way you get 3 phones the same exact problem in a row. FYI, Samsung Focus and Captivate had the similar problem in the past. Car mode is just the result of your USB port problem instead of the cause of it. What happens is something shorted out or bridged the pins of the USB port to make the phone think it is conneted to a car dock (IIRC, car dock uses a 300k resistor to bridge two pins). Some ppl with Focus or Captivate reported success by blowing out the dirt in the USB port.
As well as cleaning the USB port with an alcohol swab

The only USB cable I've used with all of them is the one they come with. I've used the alcohol cleaning method as well as blowing in the port, hopefully getting out any thing causing issue. This seems to help temporarily. The strangest part of all this to me is with this latest phone, I have zero problems all day. When I lay down in bed for the night and start using the phone is when it starts to happen. My battery life can range from 60%-30% at that time, so I don't know if that is a connection to this issue. Maybe the phone is possessed. It always seems to take about 2-3 weeks for this problem to arise. I always have the phone in my pocket, so I guess something must be happening with that. Luckily with this latest one, I bought the best buy insurance, it's just after awhile they're gonna start wondering why this keeps happening to me, and if it's my fault. The USB port problems can sometimes make it difficult/impossible to flash back to stock.

Useless responses are no better than useless threads imo.
To the OP. The likelihood of that many bad phones in a row with the exact same problem is pretty rare. Take a look at anything that's remained consistent through all the phones, and try replacing that item(s).

+1 for replacing the cord and power brick. Alot less quality is put into them compared to the phone. Just make sure not to buy cheap. And never plug your phone into anything cheap (i.e. car radio usb port, off brand charger, ect) That's not saying everything else is bad. But why risk it. Especially when you can buy brand name chargers off ebay for $5 or less.

I've only used the supplied USB cord, every time. Now even when my phone isn't confused if it's charging or not, the battery life is now awful. 5-6% per hour drain. Used to be 1-2%. No changes made by me. Also the phone has become super laggy at times. Feel like i'm using my cappy again. My apologies for starting this post. I knew I would most likely get crap for it, but my issue is very strange, IMO, compared to mine and others previous experiences. I also figured if I added to an old post, it would go unnoticed.

If he is getting 5% per hour drain at idle, yes that is horrible battery life. SGS2 is fairly easily capable of 1% per hour idle drain.

i had this same problem. it wasnt with the port but it was with the usb cables i was using. but those cables would charge the phone fine but not allow it to get a connection with the computer. swapped cables and works fine.

You've used the same cord with all 3? or a new cord with each one?
It sounds like you've got a boatload of issues going on. Personally i'd do a wipe and try a fresh install without installing any additional stuff to be sure the hardware is fine.. Once you've verified that start adding apps to see if it was a specific one causing the issue. (there's other ways to troubleshoot this, but a fresh wipe is the most straight forward and simple IMO)

i suppose.
However he said before it was 1-2 percent an hour. That's pretty much impossible while being used, only get numbers like that while not in use (idle). Even %5 an hour while being used isn't likely to happen. Guess i just figured it had to be in ref to idle drain.
lol guess we just wait to see

Several days ago my phone started behaving strangely. Whenever the phone is NOT plugged in, the battery icon flashes continuously. If i plug it in, it stops flashing and behaves normally to show the phone is charging. Also, when the phone is NOT plugged in, the lock screen says it is charging. My battery life is dismal.
When i unplug the phone the battery indicator remains at 100% for a long time, but then drops quickly.Since this started i have to charge the phone twice a day with only moderate usage.
I am now on Shostock2 4.1.5 and Siyah 4.1.1. I tried factory reset, clearing cache and clearing dalvik. I also tried installing a different kernel (dream kernel) and a different ROM (aberration), wiping data, cache and dalvik each time.
I searched the forums, and the only threads i found seem to point to a bad usb port. One thread suggested cleaning the port, which i did using alcohol and compressed air. It helped for about half an hour, and then the problem returned.
Everything seems to point to a usb port that for some reason makes the phone think it is plugged in all the time...perhaps it is somehow shorted? So, it sounds as if my next step is to replace the usb port.
Still, I wanted to ask if anyone had any other possible solutions i could try before sending the phone for warranty repair and get the port replaced (or replace it myself).
Any ideas?
You are being kind of vague here. For instance. U say u have to charge it twice a day with .moderate usage. What if your moderate usage is 2.5 hours screen on time or something. To me, that means of course u will need to charge again if u want to make it he whole day. A bit moar info? Some cowbell?

Moderate usage means (for me anyway having the phone on, wifi on, gps off, no gaming. I only turn the screen on to check email for a couple of minutes here and there, and to answer the occasional call. Before the problem started my phone used to go all day without recharging. Now, even if i let the phone sit, unused, untouched, screen off (like overnight) battery level will drop over 10%per hour. I tried using better battery stats but none of the triggers have been triggered: if i try "since unplugged" or "since charged" or "since screen off" they all show zero seconds...I'm guessing that being "plugged in" continuously is messing with the triggers.
Still, the battery drain is not really the problem. The problem is that the phone seems to think it is plugged in continuously, even when it is not. It sounds like a bad usb port, or a port about to fail completely, but before i try to replace it i wanted to know if anyone had any other possible ideas.
People usually scrub the inside of the port with an alcohol swab if I'm not mistaken. Thought I've seen that posted, never had this problems myself.

My USB port needs to be replaced due to wear ( loose fit of cable). The ones for I777 I have found are $7.00 but are port alone, ones that are for I9100 are $15.00 but are attached to the ribbon cable. I plan to take phone apart to try to determine if the I9100 part will work. The price to have it repaired by MobileTechVideos is $40.00 plus shipping.

Definitely sounds like symptoms of a bad USB port to me. One thing you might do if you want additional confirmation, is to flash back to stock firmware (to rule out firmware issues...though I don't know of anyone who has confirmed this type of symptom being caused by bad firmware) and grab an older copy of BBS that will continue to report stats when plugged in (or maybe it will still do this if you set custom ref? I haven't tried.) There is a wakelock that will show for plugged in...vbus_present I think it is. Or you can also watch CPUSpy - if it continually thinks it's plugged in you'll get zero deep-sleep.
Thanks everyone for the suggestions.i tried sering a custom reference in bbs but no luck. No matter what i try they all show zero seconds. If i look at the battery graph in the system menu, it says the phone has been charging non-stop for the past two days, which is not the case. I will try cpuspy and report back.
Get a tooth pick and push up or down on the metal insert inside of port. May take a few tries but will work. I believe it is caused by your chargers 5 little metal cables bent when you plug into phone...

BBS update
FYI - I just grabbed the latest RC for BBS, and it now has a toggle-able option to log stats while charging (with a caveat to use at your own risk...stats may be inconsistent). Might be another tool for further investigation.

I tried cpu spy. i left the phone untouched, unplugged screen off for about 90 minutes. Cpu spy shows the phone spent almost all of that time at 200 mhz, never entered deep sleep. So it does seem to be a hardware problem, where the phone thinks it is plugged in continuously. i will carefully try the suggestion above to straighten the pins inside the port..maybe they are bent and somehow shorting. If i screw up the port....well, i probably have to change it anyway

Well it's not my cable. What it does is act like it is connected with no cable being connected. Therefor causing it to act like it is charging. Then it prevents deep sleep and wakes and vibrates every so often. Really quite annoying and killer to battery life...

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 don't know what kind of Que tips you use but the ones I have don't fit. I used tissue folded over and it's still screwy. I think something's loose in the or something because sometimes shaking it makes it stop for a bit. If I get a new usb port from e bay will the one for the i9100 work in mine?

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.

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?

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.

Yep let us know how you get on, if you need to know or think of anything else, post to this thread again.

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.

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....

I'm pretty sure my charging port is broken ;it only will charge if I push it in really hard and at a weird angle ...I'm just curious if anyone has ever changed it and how difficult it is... Any info will be greatly appreciated ... Thanks in advance ......

pretty easy, just replace that whole bottom bit
im going to be doing this to my white one when it gets back due to same issue as you, thought it was the charger until i tried a few more

It was weird it was working fine then boom acted like a piece of junk .. I actually just watched that video right after I posted this thread .. Doesn't seem to bad actually ... Gonna buy the repair tool lit as well for further problems .. I am trying to keep this note 1 for as long as I possibly can
£|@$h•h°|i©
i have all the tools and a few spare notes for parts pillaging haha
but ive taken my notes apart fully a few times, just dont lose screws and have patiences
I've never taken a cellphone apart before. I took this one apart to change my usb port and it was a piece of cake! I didn't have any special tools either. Took me 30 minutes and I was taking my time. I could do it now in 15.
Wish I had spare notes Lol

I have the ame problem. Glad I have 4 spare batteries so I never have to charge! I just wonder why I have no problems passing data thru the same spot. Being ignorant, I would think if I can't charge I can't pass data either... But that part works fine.

Our micro usb sockets have 7 pins. Most have 5 unless there's hdmi. I'm guessing 1 of the 7 are jacked up. I'd be careful, one of your cords could be the culprit. It might jack up a different device if you use it.
I'm thinking the other might when I got the girl bartender to charge my phone behind the counter she probably tried to stick the charger in upside down and fudged up my port ... Sucks but its an easy fix
