Hi everybody!
I'm having some problems when charging my device. I've noticed that when I use the stock charger with the stock micro USB data cable, the phone stops charging and it just charges the battery in 1% to 5% after I plugged it on the wall, and the charging led remains on. So I've left the phone plugged into the charger for 2 hours and nothing happens, the device remains cool and the charger remains cool either.
I tested the following scenaries and the results are pretty weird:
a) I tried using the stock SGS3's charger with my Nokia CA-101 data cable, and the phone charges successfully in about 2.5 hours from 0-100%.
b) I used the stock SGS3's charger and the stock data cable, and charged my old Xperia X10 mini pro and successfully charged 0-100% in about 1 hour.
c) I tried charging my SGS3 with it's stock data cable from USB port and It seems to charge very slowly: 20% per hour.
I don't like using different accesories to charge my phone, because I read somewhere that Samsung uses diferent usb pin arrangement because of the Device ID pin.
So my questions are:
What is happening with the phone/battery/charger/usb cable? They seem working well separately but not together.
Does the samsung micro usb data cable uses different pin arrangement than standad micro usb data cable? or Can I keep using my Nokia CA-101 micro usb data cable?
Any ideas?
Thanks in advance.

Hi.
I have the Samsung Galaxy S3 it is a remarkably simple phone to disassemble and I'm thankful for that since...
I also had 6 different chargers and cables that would not charge the phone reliably, I took it to Sprint and of course they plugged it in and it charged ok when left alone not moved in any way. Well the charging for me was very intermittent and some cables not at all. It was as if the plug was inserted and removed and inserted over and over again, typical problem if the solder of some connection on the PCB is broken or high resistance for some reason.
I removed the PCB from the phone and examined it to find a micro USB mounted to the PCB with 6 + 5 additional conductors, the 6 that were in the middle of the connector I believe connect directly to the conductors of the USB cable. The other 5, 2 on one side and 3 on the other of the main 6 were broken solder joints on 2 of them. I have a really fine tip solder iron and a microscope which helps but is not totally necessary to re-wet the solder on each pin of the connector. Now my phone works like brand new!!!
I have at least 33 years experience with soldering, so this operation may not be for everyone.
Good luck,
Dude I wish I had the confidence to attempt something like that, well done you

Have you ever done simple mathematic & calcs based on the current output?
You have 2100mAh battery in SGS3, right? And you have STOCK charger. Output = 1A=1000mA => full charge (assuming 100% charging efficacy) would be 2.1hrs. Therefore, 2.5 hrs result from not 100% charging efficacy - simple.
Now, you have USB port in your laptop/computer. From USB 2.0 spec, its output is rated at 500mA => full charge would be more than 4hours.
The difference is result of not 100% efficacy of charging, but this, I assume, you can calculate by yourself (to give you a direction: how much data is spent from a phone to power the screen and to supplot media connection with computer, while charging via USB?)
Sorry that I had to give you some basic calcs from primary school, but... this is what you asked for.

the other day my phone feel of the couch while pluggd into the pc. it stopped chargibg and woukd not connext to pc.
i lost the original cable so ive been using a mini to micro usb adapter for an old cable i had for my g1 which hss worked perfectly.
thought i had broke the sockey on thr phone. had a tmobile shop check it with there cable. it was fine. so boyght a microusb cable.
everything seemed fine. charge light. usb drive worked internet tether. but then the phone ran out of battety while usb tethering. it always stays at 100% before.
with the battery low it woukf rrstart every minute whole plugged into original chargrr.
its charging but very slowly. 15% in 2 hours. checked battery pins. seems fine. i dkd manage to get 37% charge in 30 monutes once irh the phone off.
the phone doesnt even get warm while plugged in. it used to get pretty warm when cuargibg.
tried hard reset. trief reflashig rom. it knows wall charger is in. says charging orange charge light.. but it charges sooo slow...
im stuck. is this a repair jobk
Just got home and tried the new cable in my home PC. ive already lost 1% battery in the space of a few miutes usb tethering....
make sure you have the "don't charge the phone while connected via usb" unchecked. Other than that, sounds like a hardware problem.
i cant find that setting, only do not charge when the phone is on., which is off. Ive just noticed something else. the brightness setting for AC power effects the brigthness when connected to usb. I dont think it knows the difference between ac and usb anymore.

when you plug it into the wall, do you get the menu for: Activesync, Disk Drive, Internet Sharing? If so, then this is true. Really sounds like a hardware issue. I would take it back in and see if they can replace the port.
nope, when i plug it into the wall, no menu. it does seem to know the difference between usb and power. as using the option "when phone is on, do not charge when the pohone is connected to pc" has no effect with the wall charger.
I tried a different wall charger. I have a travel charger which is only rated at 500ma instead of 1amp and it charges the same. I was able to get 100% overnight. woke up after 8 hours to see the green light on, it stays at 100% with the wall charger as long as you leave it alone.
back into the computer, tethering and im loosing battery as if it wasnt connected.
Looks like ill have to dig out my insurance as its not a warranty repair (and also the water damage stickers are red, due to it being dropped in the toilete 3 months ago)
hmmm interesting. phone has been in charger overnight and was at 100% when i got up, pluigged into pc for usb tethering, despite battery dropping the green light is still on.
Ive done some searches on usb micro cables and came across people having problems with some data cables with charging, as some cables cannot cope with the large current required, but they mentioned that there phone would say this and i have seen that on my phone before with my front usb ports on my computer.
Im gonna order a microusb adabter as i have 2 high qualiity usb-mini usb cables from a G1 (which was usbed with an adapter with no problems) and 1 from a tmobile mda varia, same cable.
This has now been solved. After closer examination of the USB mini to micro adapter, it apeared that the 2 outside pins (which are for charging) had been flattened. Looking at the adapter, you could only see the 3 middle pins, but with a torch you could see that the oiutside pins were compelty flat. from droping the phone its oviously twisted the connector resultinin in flatting those pins.
I went back to tesco and bought the same USB kit which comes with a mini USB cable and several converters to fit different phones.
AFter hooking up the cable and micro usb adapter to my PC, my phone was within minutes showing increase in battery charge. After a few hours with usb tethering enabled and watching videos online im up 2-%.
The cable i bought for £7.99 which is micro usb though doesnt mention any HTC phones (mostly nokia) will connect perfectly for data transfer and the phone appears to say its charging. It looses power suggesting insuficient charge current. Maybe its the rom im using disables thsi warning as i have seen this before when i connected my phone to the front usb ports, but it works fine with the back.
So, it seems i have not damaged anything apart from the usb adapter i was using.
All is well, and im charging at a fast rate with USB while tethering.
Please close this trhead as it is resolved.
Final update. After several days i have been usb tethering and charging absolutly fine. Using 1amp charger charges fast!
Even from a dead battery can plug into usb and have the phone bootup.

So I went out and bought a 2nd USB cable to leave at work to charge my phone. But for some reason the USB cable I bought doesn't charge the phone...instead it drains the battery..??? The light is on and the icon shows it is charging when I have the USB cable connected and I can even mount the SDcard with it. But the battery percentage slowly goes down. The USB cable that came with the phone works fine without any issues.
Is there something special about the stock USB cable? Do I have to buy a certain type of cable to make charging work?
I bought another two cables, even used a Motorola USB cable but never noticed that... it never happened to me.
My guess is:
Fact:
- charging through the pc USB port is so slow, to get full charge you need 6-8 hours compared to 1.5-2 hours through the wall..
Scenario:
You are using your phone or running heavy application while charging it so it drains more battery than charging ..
Just a guess.

I have a Samsung SGS2. This charges fine off the original charger (650mA) , a new trent usb power pack (450mA), computer USB port (450mA) etc using a variety of cables.
I purchased a USB charger from a major retailer (B&Q) and found that when charging the phone a) had a totally unresponsive/dodgy touchscreen b) actually barely charged. Swapping the usb cable I was using for some cables seemed to fix the problem, but most didn't work.
However using the "failing" cable in a amazon kindle usb charger, and again the phone charged fine.
My conclusion is that the replacement usb chargers are faulty in some way - or at least not compatible with the SGS2. Possibly down to perhaps data pins not being shorted or similar.
Interestingly the exact same issue is observed on an HTC Sensation further suggesting it's the charger to blame (we have 2 of them - behave the same)
Can anyone explain/elaborate?

The unresponsive touchscreen you experience when using the charger is the result of the charger creating too much noise (ripple) which disturbs the electric field of the capacitive touch screen. Hence the digitizer is not able to work reliable anymore.

Shorting the data pins will allow the phone to identify the charger as such, compared to a standard USB port. The phone will then draw more current then it does if it detects a 'regular' USB data port. From that point of view shorting the data pins should not have any influence. However if more current is drawn from the charger the ripple will increase and therefore the disturbance of the touch screen could aggravate.
In the end the problems you are experiencing are due to a charger of poor quality.
None of my micro USB cables will charge my E970 without a "slow charging" notification except for the cable that came with the phone. Even the venerable 6' monoprice cable isn't up to the task. HTC cords aren't cutting it, either. Does anybody have any 6'+ (ideally a 10') micro B cables that will charge the phone without slow charging? My monoprice 6' cables (i have a bunch) barely keep the phone from losing charge when serving up LTE hotspot, where as the LG cable charges it whilst doing whatever I can to suck down as much current as possible.
Also, I really don't want to short data cables. Somehow the stock LG cable does full current while maintaining data capability, and that's what I'm looking for.

OEM LG cables can be found almost anywhere used so that shouldn't be a problem. Otherwise, you may be looking at the wrong end of the cable. I have a spare tablet plug charger that puts out up to 2 amps and that seems to be what works best for me no matter what the cable. You might want to look for one of those instead of just buying more cables.
FWIW....I had the opposite result. The cable and adapter which has been near my bedside for the last year (for my HTC EVO 4G) kept giving me the slow charging notification on my me LGOG. If I used the LG adapter and cable all was well, but it was shorter than I wanted. I changed out the adapter and kept the older long cable and still got the slow charging notification. It seems most of my existing cables have this issue...even when using the new LG adapter.
I have not looked into power capacities on the usb cables since I charge each night and don't need to recharge during the day. Didn't expect there to be a throughput difference, but the new LG cable does seem to be different.

What is the part number for the oem charger and USB cable?
I use a Samsung charging cable with my LG plug and it charges regularly. I love the Samsung cable because the mirco-usb plug is asymmetric so I always plug it in correctly the first time, every time. Even in the dark. The cable is pretty long too. I don't use the Samsung plug because it only outputs 0.7A though.

I also use a cheapo USB male to female extender that I got off eBay at my gf's place and it charges just fine too.
I'm having the opposite problem, I have had my phone for a month, out of no where the original charger is throwing up slow charging icon. Wierd

Same problem here, just started about a week ago. It doesn't matter what cable I use it keeps switching between slow charge and regular charge.It charges without problems when the phone is off though. Also when I plug my phone into my pc it keeps disconnecting every few minutes. I'm starting to think its a problem with the phone itself and not the charger or cord as they work fine with all my other devices just not the Optimus G

I use all sorts of cables and so far the only time I see "Slow charging" is when it's plugged into my laptop or one of my USB hub. Those are the only times I could narrow mine down to.
In the car I use cheapo monoprice cable and charger, in the bedroom it's using the charger and cable from my HTC inspire. By my PC I have a Belkin 6 plug 2 usb wall charger installed with the stock cable, and at the office an iPhone 1G wall plug. I don't think I have even plugged in the oem charger that came with it.
The thing is.. When I use original charger and original cable I had with phone in the box, it charges so slowly it can actually discharge while for example using skype.
Also funny thing is in settings/more/battery (android 4.3) it shows Charging (USB) when I am connected to the wall socket. The app "Galaxy charging current *lite*" shows it is receiving 460mA right now at average. It takes like whole night to charge. (at the time of posting it was 460mA, but I have to notice ,that using this original cable and charger from wall socket, phone itself somehow changes how much mA it takes as it varies from 100 up to 500 from long time observation)
When I use small micro usb – usb cable from my old Nokia 5800 Xpress music, it is charging at 1000mA and can charge even when using skype or anything else. With this cable I can charge from 0% to 100% in about 1-or 1,5h. (Here it is always constant - 1000 mA on average using that app)
I was googling and reading some posts from people with some S3 charging problems, and found that cables are the reason. I have noticed by visual comparison of S3 original cable and nokia cable that on the micro usb side, S3 cable has visible only 4 pins but nokia has visibl 5 pins.
1. Is the pin amount on usb micro side the reason for slower charging rate ?
2. But why the hell my phone thinks I am charging from USB when it is connected to wall socket when using original cable and charger ?
3. Is it safe to use that nokia cable to charge my phone ?
Thank you for replies !
Throw away the faulty charger, rating of the replacement is irrelevant as the phone controls the current used.

Hi, thank you for your reply. I apologize, may be because english is not my mother tongue, I do not undesrtand clearly what you are saying. Especially this part "rating of the replacement is irrelevant as "
May be I described my problem not accurately. I attached the photo of things I am writing about. I use still the same charger (number 1) I just either use original samsung cable I had with my S3 (number 2) or original nokia 5530 micro usb cable (number 3)
With S3 cable and original charger (1 + 2) it charges slowly and app in phone shows it gets at maximum 500 mA. Full charging (from 0% to 100%) takes about 8 hours at least. Also, sometimes the phone shows its connected to USB, although I am connected to wall socket. The thing is, that even when it shows AC, the app in the phone still shows it is getting somewhere between 100-500 mA. So charging is still slow. I have also noted, that current changes during the cycle of charging. Or even when I unplug and plug the charger, it sometimes changes the current (mA shown in the app)
When I use Nokia cable (1+3), current is always 1000 mA. Charging time is something more than hour (from 0% to 100%). Using the same charger, just changing the cable.
So I am unsure if it is safe to use that nokia cable. Can it somehow damage my battery or phone ?
Is the behavior of the original charger and cable (1+2) ok ?
Throw part 2 away.
Part 3 will not damage your phone.
