USB connection is acting up. Charges only from PC

Hi there,
The phone in question is a Galaxy S i9000 with the latest CM10 (same problem occurred with CM9 and another rom, not based on CM I believe).
First of all, it never shows any signs on the phone that it's charging. However, when connected to a PC, it does charge (it doesn't look like it at first glance, but the battery icon fills up). When connected to a wall charger, nothing happens. It does not charge. I also can't connect it to the PC in order to transfer files etc. Just charge it.
I cleaned the usb socket carefully, but that did not help. I actually think it isn't a hardware problem, because this problem has sort of been coming and going during the last few days, and as I've said it charges fine via the PC.
I've tried 3 different roms, but no luck. Also tried different cables and wall chargers obviously..
Your help will be much appreciated!

Apparently over time the USB slots tend to get damaged due to constant usage, had this problem with a china made charger ( shows charging but never charges) and still lately even USB cables seems to need some replugging or slide movements to get connection. For insight , try the cleaning method.

S4 will not charge with AC charger; only USB

Last night I was charging my S4 in my car adapter, but noticed the cattery was still going down. I went home and plugged it into my AC (wall charger) and went to bed. The next morning the S4 was dead and couldn't charge. The only solution was to plug it in my computer and went an hour for it to get some charge back.
I have a root i337m running rootbox 4.1, and I went into TWRP to wiped the phone and installed the ROM again - no luck.
Is this a battery issue, a software issue or a whole device issue? Thanks.

I don't think its a rom issue. I tried charging via USB as well and had phone charging a few hours and it ate crap. So I only charge via AC outlet only. USB charges but at a very slow pace.

I made an error in the OP - I meant to say I left it to charge on the wall and I got nothing.
Right now, the charge light doesn't even come on if I plug it with AC.

Maybe see the results by changing the charger you're using?

I've tried 3-4 different chargers and cables, same issue. Charges slowly through PC,doesn't charge at all with AC. Did a factory reset after reverting to stock FW, no luck.

I doubt it's a ROM issue, but there's no harm in reverting back to stock to see the results (assuming you've backed it up). If it all fails, i think you should unroot and send it to Samsung for the warranty. Software problems are somewhat easier to fix here than hardware, so it may be the best option to let Samsung handle it.

I had similar problems with my Note 2 before and now with my S4. What I found was, sometimes the usb cable wasn't tightly plugged into the wall charger. Once I've made sure of this, I've been able to charge (AC) every time.

I found this article that indicates that the S4 is looking for special sauce on the D+D- pins.
http://www.anandtech.com/show/6914/samsung-galaxy-s-4-review/2
Obviously the Galaxy S 4 will charge with any USB charger, but the charge time will simply be longer. Samsung uses a voltage divider and signals the presence of their own charger by sending 1.2-1.3 V across the D+ / D- pins, this is similar to what Apple does with 2.0 or 2.8 V across the pins for various USB chargers they've shipped over the years. This signaling is essentially Samsung's proprietary tablet charging signaling which they've employed on the Galaxy Note 2 and now SGS4, in fact the two use the same exact charger, so it's worth tossing out your old ones and getting the appropriate one to take advantage of the faster charging.
However I do not believe this to be 100% true. I think not all chargers will work..
I took a charger that is very vanilla (Wall charger but the D+D- pins are NC) and it works with the S3 and NEXUS7 but does not work with the S4.
This charger uses a stock USB cable so I took a wall charger that had gone bad but had a dedicated cable and hacked off the end and wired up my own cable...
That works! So it appears that the S4 will only charge properly with certain chargers that do something to the D+D- pins (either shorting them with a resistor like the article indicates
I then took a look at the cable I used to replace. It is a Motorola cable and it has the ID pin pulled high built into the cable... So I suspect that is required for the phone to work... But to fast charge it will need the special sauce indicated above!

Had the same issue and found the solutions which worked for me. Go into the developer mode and deactivate the usb debug mode.

Had the exact same issue. I took a soldering iron to my charging port on my phone. Problem solved. The ID pin had a bad joint.

I have a strange issue, my s4 is detected by pc, charges normally with usb ( wall or pc charge ) my battery is full but when I take the cable from microUSB port and s4 should work with the battery, turns off and consumes no battery, it's like refusing to use the battery and that it is full! battery checked on a sph l 720
I've tried installing other roms with safestrap but I still have the same problem, refuses to consume battery and while the battery is at 100% ,my s4 shows 0% if I disconnect the usb cable... game over. However, I can be on the safestrap menu for hours only with the battery, no problem, is a problem of rom I think but did not know how to fix it .. : (

I'm having the same issue as the original poster. The USB port is good, charges fine when connected to PC (although much slower because of different mVS). Have tried amidst everything and nothing fixes it. I've turned debugging mode off and back on, restore to backup, complete wipe and reinstall of 2 ROMs with and without apps, fix permissions, different kernels, different USB cables... The adaptor is in good condition. But when plugged in while on my phone doesn't recognize that's it's connected. Previously out would give a false charging reading. If off sometimes I got the grey bar battery but note is just vibrating every few seconds. Idk what to do...

I'd guess it's the charger. Get a new one

I had the same problem. S4 will recognize charger as USB charger, not AC. solution was to clean usb port connector, was some cloth covering wires. then restarted and worked ok

I am having trouble charging the phone the same way. I have reset the phone 3 times and still can't get a charge.

[Q] Charging Intermittently Stops and Starts?

For the last couple months, when I plug my nexus in to charge, it intermittently stops and starts charging. It doesn't always do this but when it does you can tell because the screen will stay lit up with the "charging x%" label flashing under the clock. The screen stays lit and the charging label flashes because it is as if you are pulling the charge cable out and plugging it back in over and over again.
I think I read about this issue a few times awhile ago but I can't find any mentions of it now. I know it happens with the orb charger sometimes but I just use the stock LG charger and cable.
Does anyone have any idea if it would be my phone, the charger, or the usb cable?
I sort of thought maybe after plugging it in so many times (since I got it basically right after it launched) maybe the usb mini charging port got worn down so it has enough play that the charge wire can't always get a grip on it leading to the intermittent charging connection. My charging cable hasn't ever been bent around much so I don't think it would have been damaged.
I am running the latest official CM nightly with faux's kernel. This problem has happened at least twice when I was running it completely stock as well as each time I tried several other kernels. Formatting and restoring never helped either. So I doubt it is a software issue.
Usually when this happens, I think it also winds up switching to usb charging mode because charging is unusually slow. I'd say 90% of the time though if charges without this intermittent issue and in AC charging mode very quickly.

What happens when you connect your phone to your PC? Does it work, or does it connect and disconnect continually? Does it charge fluently?

On a PC it's a completely solid connection. It has always charged solidly from a computer.

I have tried one other charger and wire a few months ago but I only used it for about 10 minutes. I'll try it again today and charge it overnight for a better test. It didn't have the same issues but the plug was definitely tighter to plug in. Could the lg charger's cable have worn down or is it just not made to fit a tightly? The LG wire does wiggle a tiny bit while the new charger wire doesn't move at all. Does your LG usb cable have a bit of play?

Mine doesn't wiggle, but that wouldn't be the problem. If it's charging fluently while connected to the pc, then the adaptor itself might be the problem.

Can you RMA a charger with google? I think you're right. Right before the problem starts, the charger starts making faint intermittent buzzing noises. It's not an unusual buzz, it's that normal sound that you often hear with chargers and other devices. The thing that's weird is that it is intermittent instead of a steady sound. I'll see if I can get it replaced.

[Q] Galaxy S4 won't charge

I should clarify the title by saying that trying to charge this phone is resulting in a number of odd results.
So firstly, I've tried using the wall-mounted AC charger. I then tried using USB on my computer, in 3 different usb ports. The phone was charging perfectly less than 24 hours before this problem began.
I plugged it in as per usual, and it didn't show the little lightning bolt on the batter icon like it should. It wasn't registering that it was plugged in. I tried plugging it into my PC, and it wasn't showing that it was connected via USB. In addition to that, my computer was failing to install the drivers for it. I went back to the AC charger, and tried a few different outlets, including one on a power strip. Nothing worked.
I searched online, and found that other people had this problem, and could only fix it by resetting to factory default settings. One person even had to do it twice to get it to work. So I did this, and it still didn't work. I tried charging my old phone with this Ac charger and cable, and it wouldn't work either. So I thought it must be a fault in the cable. So I dug up the cable (also micro-usb) for my old phone, and tried it. It worked just fine for my old phone, but my S4 still had the same problem, but with something new. It would say "Dock connected" but still not charge.
As of right now, it seems to be charging properly with my new AC mount and old usb cable, but I'm worried that this could happen again. Considering this seems to be a problem for other people too, what should I do about it? Is there some way to prevent this sort of thing from happening? Was it purely the other cable, given the fact that it didn't work with my old phone either? I'm on an extremely tight budget, and this phone is my only way of being contacted for job interviews, so having it in working order is very important. Any advice would be very appreciated!

Having exactly the same problem... couldn't find over the internet a solution yet or a position about it...
Affraid it's a hardware issue and have to send to the assistance...
Anyone know what to do?

Yup having the same issues - but i noticed only having charging issues when battery reaches 20% or the low battery notification pops up
it detects that a usb is connected but it wont charge
Solutions:
- dont let it go below 20 which is ****
- some people claim that if you use a 5pin charger instead of the 4pin which samsung includes solves the prob

Mine is a little more serious I think... haven't found a solution like that yet.
I have to connect/disconnect multiple times and it suddenly works.
But between those connects/disconnects it presents multiple problems, it appears on notification bar "Dock Connected", sometimes appears "Dock Connected" and on the notification bar appears "Suggested Apps (Anchoring)", other times it appears "Dock Connected" and the volume bar appears on the screen and stay there freeze (the phone works, but the bar doesn't disappear)... Sometimes the phone starts charging and suddenly stops, other times it says it's charging and if I remove the charger it keeps the charging symbol on the battery icon...
It's completely crazy, gonna take to service I guess.

Have you tried blowing out the usb connector on the phone with a can of compressed air?
If there is a minute piece of dust there it may be shorting something out - error that dock is connected. I know this happens to other phones, there was a big thread about it on the S3 forum. Might be a simple little thing like that...

Unfortunately that doesn't work for me, will send to service, let's see.

have you solved this problem and how?????

Yep, chalk up one more with the same problem!
At first I thought it had something to do with Aviate, a custom launcher from Yahoo (actually a pretty sweet one at that!)
But I guess not.
My work-around is to reboot the phone while connected. It charges fine while turned off and seems to keep charging when booting while plugged in.
Still... this is a stupid work-around and I want this fixed properly.
Any news from any of you guys?

Had this problem today. Suddenly out of nowhere "Dock is connected" message appeared after plugging the charger in and out. Tried to clean out the dock with stick and cotton on the edge. Then turned off and plugged in charger. Problem exists. Phone charges but stops regularly. It is very annoying when you dont know how to fix this kind of problem.
Any new solutions?

Right after this post, I froze the app "battery doctor 4.9.2" using Titanium Backup Pro (you can just uninstall it i guess). Then just plugged charger and now it's already Almost 90% without any interruption.

Amazing! I've dealing with this problem for weeks and internet didn't give me any good answer, but the whole problem was a baterry monitor apk that for some reason was interfiering with the charger. Thank you so much!

I had this problem too and in my case it was a hardware problem. When i start the charging it kept repeating the start proces of charging with the vibration and the grey battery icon(in case the phone was turned off). The battery icon with the green charging light just didn't showed up. I tried many things but nothing helped. I let the phone keep charging for the whole night but in the morning i saw that it didn't charged anyway!
Then i went to a local phone reparation shop(none official samsung) and they knew immediately recognized the problem and it was the usb/charging connector where you plug it in the phone. They fixed it in 1 hour for a cheap price and from then(i think a few months ago) it charges back perfectly. It seems it's a disease with S4's.

In my previous post I was happy thinking that all this charging problems were solved after uninstalling battery apk. But, in fact, my S4 charges very slowly after that incident. I have tried two other samsung adapters (galaxy s4 mini; grand prime). First one results the same (up to 5 hours charging), the latter was comparably shorter (up to 3 hours), but still slower than it used to be (2 hours normally). So I highly suspected the hardware might be the reason. Thank you for your information, now I will also have the phone checked at some local repair shop. And give feedback of course.

You probably got some water damage in your port. What you need to do is clean it. I used pure alcohol and a toothbrush for that. After that I flashed a custom kernel so I could enable fast charge true usb.
That's the reason your phone is charging slowly, it thinks it's connected true usb. So you need to boost the usb charging. After a few charge cycles I could revert back to my standard kernel and the problem was fixed.

I think ur right Lenny.
Mine S4 got wet last weekend and now i am also getting the " Dock is connected" message when i plug in the charger cable.
I can charge my phone but sometimes while charging i hear the sound go off and on what you hear when unplugging the charger.
I will try your solution and hope it will fix mine too. Thanks for posting ur tip!

I suggest you go buy a new genuine cable for an s4, the s4 does actually require a special cable capable of 2A charge rate otherwise you can end up in all sorts of bother.

Thank you all for sharing tips. I cleaned the port as suggested, then replaced my cable. Now everything is back to normal.

Same problem - galaxy s6
Hi there - same problem, on my 128gb s6. started this morning. Yesterday everything fine, would charge when connected via USB to both laptop and to regular samsung usb power unit. Have now tried 3 different USB cables including the samsung cable, 3 different usb power units and of course tried all 3 cables in laptop usb port. Have checked phone's usb port - clean as a whistle. Have rebooted both connected and unconnected. Started getting 'dock connected' message, now it just wont charge, although starts up fine. I take very good care of the phone, so no water damage or untoward shock damage (never get it wet, never drop it). Remaining battery charge seems to fluctuate between 30% and 40+ %, depending upon whether it's plugged in or not. If I turn it off, then connect usb cable, the phone just reboots, still not charging. I then turn it off and see no green battery charging screen, as I used to seen when connected but turned off. Should I just hard reset and take to repair shop? Still under warranty.

I would return the phone for a warranty repair. Software would not usually prevent the phone from charging when powered off.
As a final test, see if the s6 will charge wirelessly, assuming you have access to a qi charging pad and the s6 has a built-in qi receiver like the North American version of the s6.

[Q] Charging is only possible through USB

Hi
I have the Galaxy S5 for about 1 month now and I like it very much. But two days before, I noticed issues with charging the phone through the AC Adapter (Samsung original USB Charger) - the phone did not charge during the night. So the phone stopped charging with the wall charger. I tried out many other USB chargers and also USB 3.0 cable. Without success!
It charges just fine when it's plugged into my laptop or desktop PC.
When the phone is turned on and I plug the charger in, nothing happens. The battery condition in android is still "discharging". But when the phones is turned off and plugged into the wall charger, it vibrates in intervals and the screen stays blank (the little battery animation doesn't appear). Removing the battery and replacing it does not help. I tried almost everything...
Has anybody an idea? Otherwise it seems to be a hardware problem. Same issue also here: Androidforums
I'm on OMEGA 5 ROM now with OMEGA Kernel. I cannot believe that the OMEGA Kernel has something to do with this issue.
Thanks for any help

It seems that it was a hardware problem, probably because of some water inside the USB connector. After some days I blow out the socket with a spray duster and since this time, the issue never happened again. :good:
I think, I will never test the water resistance again...

Did water enter the usb port and was the flap closed or not?

The flap was closed of course. I don't know if water has entered into the socket, but I think not.
One day after my post, the issue happened again. Now, I have updated to OMEGA 5.1 and flashed the Samsung stock kernel instead of the Omega Kernel. Now, the issue never occured again.
I cannot believe that this is because of the kernel, because the issue was also when the phone was turned off.
Now for 1 week, I never encountered the problem again
