Charge Problem ? - Galaxy S II Q&A, Help & Troubleshooting

I have recently tried to clean the dust and everything else from the charger/usb port but didnt fix anything.When i connect charger or usb my phone dont charge.Nothing happens.Sometimes when i connect charger it says " USB MTP connection " smth like that.Before that i had a problem... my phone went crazy.My phone opened Driving Mode,Voice Talk etc etc when ever it wants.And i read on net to clean the port.Now i clean the port but charging dont work anymore.But phone dont do strange things anymore.Iy just dont charge.I connected the charger into the port and with a special screwdriver I test if the nergy comes inside the phone,in the place where the battery is puted.The energy comes there but my battery dont show any signal that is charging. So Conclusion : 1.Might be my charging/usb port .Maybe i broken it when i tried to clean. 2. In the other side if the energy comes into the phone than the port is OK and might be my battery. So plz someone tell me if anyone knows what is happening with my phone.Thnnxx

[Q] Problem with USB port and function

Today i found out my SGS2 have problems charging the phone, not only that. i also have problems with USB file mode, and keis mode. and if the phone is turned off. i only once got it to charge without booting. else when i connect the USB it boot the OS.
What weird thing is, that ODIN works without problem every time!
The problem appeared after upgraded to Darky Rom KG6 with jkay mod. but don´t think it has anything to do with that.
I reflashed to a Stock KG6 (still same problem)
From OS restore to default, and format (still same problem)
tried to flash back to KE2 stock. an but on CWM, and clear battery stat, and system cache.
flashed backup with a KE2 Kernel (still had the same problem)
What i found out is that, when i disconnected the wall plug charger, the phone still was in a state of charging. and it don´t give the sound notify when attaching the USB. but when touch the USB cable it suddenly charge and give the sound. but it can also go in MTP mode. or start Voice recognize.
Could the be a faulty USB port on the phone, or can Battery State and kernel updates have something to do with this problem?
im now pretty sure this has something to do with the USB port. when i just spoke on the phone. it suddenly began to change between Car mode a normal.
i than tried an alternative why to deal with the problem. I tried with a hairdryer after taken out the battery, sim and sd card, and carefully heat the back of the phone.
for 5 hour there has not been any problem. both the desk dock, and wall charger is working.
got a dejavu from the xbox days and RROD.
I have the same issue. I think the USB port is faulty.
The phone reacts to different electrical resistor values on some pins of usb port that triggers car mode, desk mode, etc. So, somthing is faulty in the usb board that reports to the system that has something connected to it: charger, car dock, desk dock, usb jig, etc.
I can't find any solution on the forum, I tried with several roms and got nothing.
So... I'm waiting for a USB Jig to reset counter, back to stock rom and send it back to store for warranty
My problem seems to be fixed by using the hairdryer on the usb port. I think the problem appear from the why you hold the phone and if your hånd become sweaty. Because there are nothing to protection the usb port like the sgs1.

Did you really fixed just cleaning?
Yes it happening two times and it fixed it both times. So there is a pattern

[Q] S2 not charging

Hey
my s2 wont charge from the wall charger or the pc. I tried
1- clean the port with comppressd air and a needle-no luck.
2- I swap batteries-no luck.
3- changed roms including going back to stock, formmating, wipe data and so on-NO LUCK.(now runing ics 4.03 rooted with speedmod 3.1 kernel)
4- tried other chargers and cables.
apperantly im facing hardware issue.I took it to a lab and they told me that it's not the usb flex cable but it's something to do with the voltages in my s2(they didnt know how to fix it) is anyone know what he was talking about or if there is anything to do other than sending it to samsung for reapir??maybe an app or something?
p.s
no warrenty
s2 will connect normally to pc but wont charge
my only option for now is to buy a couple of batteries and a s2 battery charger
Thanks
as you mention, swapping battery don't help, what make you think buying couple of batteries and a s2 battery charger will help?... (ignore this part, i get what you mean now)
you might have hardware failure, but i am not sure either, can provide more info? what do mean by not charging? what did you do prior having this issue?
did you flash any ROM prior to this?
TNX for the reply
prior to that i went to jellybean rom but still i could charge and it also worked well when i went back to ics
my guess is that- I have an old toshiba laptop and i plugged the phone with usb cable and nothing happend, it wont recognize my s2(my s2 was working fine till i plugged it to the toshiba laptop) and now the usb port on my laptop is not working and the s2 is not charging.I think it got zapped and the motherboard or ressistors gave up.everything else is working).
all the tech guy could say that i have different voltages and it's not the usb flex cable.
trying app called voltage control but i dont relly know what setting to use...
i think going to samsung service cetner is my only option...they just gonna tear a hollle in my pocket
your case is a bit complicated. guess service center is the best option for now. normally the phone got voltage limitation which will control the amount of voltage input so you don't fry your phone.

[Q] my galaxy s3 is not charging normally

hello ,
my phone is not charging normally.
sometimes i see USB charging while im charging it on AC.
i wiped my phone and tried installing a new ROM and a new kernel ( ARHD 15 and perseus kernel) still the problem exists !
After i unplug and replug , my phone can charge again ! but this problem happened to me 10 times and i still cant fix it !
any solutions ?
Hey buddy,....
I dont think so that is the probelm of your phone...
1. On wall charge , check whether its perfectly fits or not... (the same thing happend to me also)
2. Always use original Data cables... coz some of the data cables are made for low end device only.. they may not support USB charging..
Try to use Backside USB ports rather than Front USB s....
:good:

[Q] S3 charges only in Download Mode

Hello XDA
This is the first Q I have I managed to work my problems off by myself to this point. Straight to the matter at hand:
My S3 stoped to charge normally on:
Wall socket solid cable charger
Wall socket usb cable charger
USB plug to a PC
External battery
On a turned off device it only shows the loading battery no charging
On a turned on device in normal boot it shows charging but no charge is applied (checked with various software)
It only charges in Download mode (slowlly due to the fact of a turned on screen)
I tried diffrent chargers, cables even batteries nothing really helps
Also its not being recognized by the PC when plugged in in normal boot but it's being discovered in Download Mode.
I was able to flash Stock Rom by ODIN but it also didnt produce a solution.
The only thing that comes to mind is to flash with a repartition but i cannot find the proper *.pit file and I don't want to do this before consulting the community.
I can reset the counter and send it to the service but I think that this is a software issue not a HW one.
Can anyone offer some assistance?
UPDATE:
The device when booted normally and pluged into "holds the charge" it dosent go up but it doesnt go down.
Pretty fun !
I think it's an issue with your kernel. Have you flash your device with a custom ROM and/or kernel ?
Well I was running PAC Rom for S3 at the time so the Kernel was based from that.
After that I Changed to XXEMA2 CodecROM 1053 Black Edition with Siyah Kernel still same outcome... And after that returned to the roots with Stock ROM with Stock Kernel
I have the exact same problem on my Galaxy S III for Sprint (SPH-L710). Did you ever find a fix for this???

I have the same problem too.
Did anyone ever fix it?
The phone charges when in recovery/download mode, pulling 300 mA from PSU, but only 60mA when connected and turned on.
Im using a normal usb cable, and have short the D+ & D- Pins.
I've charged the battery in a third party battery charger and that works fine, I also have a wireless charger that too pulls around 60 mA
Maybe you all need to change the USB connector module at the bottom of the phone? I've seen these break or do strange things in many phones including Samsungs. Not sure if they eventually get broken due to overheating or what the issue is, but that would be my guess.
i have a pb in my i9300i my cell going to downloading mode automaticaly

[Q] Unable to connect to pc (no it's not a driver issue....)

Hi,
Having a problem since a few weeks with my s3.
Normally i could connect wiht my phone to any pc,, without any problems. Either it be unix, win, whatever...
Suddnely it stopped working, only thing that happens is charging when i connect it to my pc. Different cables tested, original one, etc..
Connecting it to different pc's resulted in a no go.. so it must be phone related.
No windows pop up, or anything!!
So I figured: Let's install a new rom.
Tried ultima 15 rom, got a different CM rom now (sentinel)... all to no avail.
Is it possible that this has something to do with my radio?
rom info:
android: 4.3
baseband: CEEMG2
Anyone have an idea what to do? Even ADB push ain't working..
See your identical post
I experienced the same problem when m using the Galaxy Nexus S But it was solved by using the app from play store named SD booster... In this app m just set the value of sd card to 1024 give root access and Boom my phone is connected as normal
If this not help then i seriously recommend you to replace the charging port of the mobile through samsung outlet
Go into developer settings, some ROMs may have different ways to get into develop er setting and after you get in make sure USB debugging is enable ^.^
Sent from my SPH-L710 using XDA Premium 4 mobile app
Usb debugging is not required for phone to pc connection see basic faqs and guides .
But as OP has ruled out drivers and cable that only leaves the phone so its worth trying .
Usual replies are
Drivers
Cable
Dirty USB Ports
Not connected to main-board usb port .
I had same issue with my Galaxy SII and when i took it to service center they said mother board needs to be replaced.
So after that SII was good as new.
Got same problem here.
phone is charging over usb , but no data connection (tried different usb cables, different usb ports, different pc etc) but nothing..
also.. tried in download mode and so (after reading forums..) but without success.
then i decided to dissasemble that phone and look, what's inside that beast
cleaned usb port (inside, with contact cleaner), resoldered all pins and etc..
reassembled it back to one piece again and still, no data connection, but only charging
so, here i am, what to do next ? change the usb port on motherboard ?
(visually, everything looks right, good solder points and etc.)
Thanks, Martin

if anybody interested:
i've got it working again :victory:
basically, the problem was the hard way (crap usb data connections on motherboard)
soldered new ways for data+ and data-, and now it's back alive again...
(pictures of ways in attachment)
Martin
see you fixed it already but a note to others :
try using usb port right on the motherboard instead of the case front panel usb ports.....connecting to the front usb ports didn't work for me on some roms, but the rear one always connected so I just have a long cable running out of the back to connect my phone and it works on all roms I've used so far
Nice work hani93, i unfortunately do not dare to desolder and solder this stuff
I've noticed another thing though which is weird!!
When i tried to charge my phone via the power charger (the ac one?), when i check my battery view it still says that i'm charging via USB.
I don't think this is correct, i thought it should say AC or something and when charging via USB port on pc it should display USB?
I think this might be one of the issues that it's also not popping up on the computer.
Anyone know what is causing this or someone can confirm that when charging via power supply it should say something else then USB?
Just confirming your question when charging by PC it says (USB) and when its charging from the Mains it says (AC).
hmmm... guess it must be a hardware issue then?
Either usb port or mainboard... christ...
open it up and cleaned the contacts a bit of the usb port...
Still not functioning..

try to go into Download mode (volDown+Home+Power) and then connect usb, same situation?(eg, no data connection to pc ?)
if nothing again.. try to clean usb port inside (where you plug usb cable), sometimes there is dust and etc. then it stops working.
also, how did you clean contacts on motherboard ? i suggest to take soldering iron with clean bit, and drag iron along the pins.
