[Q] S2 not charging - Galaxy S II Q&A, Help & Troubleshooting

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] 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.

[Q] Phone recognizes AC as USB charge

Hi all, I just realized a problem with my Galaxy S2, when I charge it with my AC Adapter (the original one comes with the phone), the phone recognizes it as USB, it shows UTP (or UT... blah blah i don't remember, the same sign when you connect your phone to your laptop to copy file). Not only that, what disturbs me is that the charging current now is USB too, I didn't realize that 'cause I used to charge over-night. But now it has been charge for 4 hours and still not full yet, I download the "current widget" app and it shows exactly 451Mah , I checked on Extweaks's Misc Tab and nothing's wrong, I recheck and restart, calibrated battery, still doesn't work.
Who has the same problem with me and knows a solution? 'cause I can't wait for my phone 5 hours to charge in an afternoon like this
I'm using Checkrom Revo HD 6 (2.3.6), Siyah lastest ver for GB, I don't install anything involved battery or scripts or internal tweaks 'cause I'm no pro
P/s: Sorry for my clumsy English
First of all you should try another charger. If the charger is reported as USB device it is probably defective (at least the short between the USB data lines seems to be missing). The slow charging of the phone is just the consequence of the charger not being detected as such.
I think there is no use changing something on your phone as long as the charger is reported as USB device.
May also be worth checking the USB port is fairly clean? Some GS2's (including mine) have required a new USB port due to false reporting of USB status, e.g. charging symbol without actually being plugged in. Hope you are not in this category!
Good luck
Thanks All, first I dont think the adaptor is defective, 'cause if it broke down, it would not be able to charge at all, in this case it shows exactly the usb voltage charge, it.makes me think it's the fault of the phone.
And I think cleaning the port is a nice idea I havent tried, I'll do it and tell the result latet

[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] My S3 is not charging

Like a week ago my S3 9300 was taking longer and longer to charge now it won't charge at all, now is always stuck at 0% if i turn it off it will charge but very very slowly, i don't know if it's the phone or the battery maybe someone here had the same problem and could help me out a little, btw i have it with CM 10.1 thank you
Alejo
Had the same exact problem with my i9300, got it out of warranty repairs yesterday. Was using a custom rom, but the same thing happened when I finally managed to flash it back to stock (had to manually press the microusb-cable as hard as I could into the phone all the time in order to get the phone recognized while Odin was working, was the longest flash ever lol..).
Remember reading about cold solder joints etc before sending it off, so if your phone is out of warranty for some reason you could replace the charging port yourself. Replacement part costs ~5$ (eBay) and if you got the skills it shouldn't be too hard to replace.
EDIT: Actually mine didn't even charge when power off, so I was pretty certain it was a bad solder joint or some other physical problem.. Have you tried cleaning the usb port with pressured air or just blowing into the port? Could be some pins of the usb port blocked with debris. Also check your usb cables, there are those with 5 pins and those with only 4. Saw the difference in charging speed while the thing was still working.

Well actually when i plug the phone into the PC it will recognize it and i can access the files in the SD card and Internal Memory and everything at the moment it's turned off and it's charging.
I have the problem that the phone only want to charge with soms chargers.
I can connect the phone to the original charger or to a pc or any device without problems, the phone will charge.
Even with an old blackberry charger (only 2 wires, no data) and car charger can i charge without any problem!
But when i connect the phone to the htc charger of my old phone, or to an iphone charger i see the phone is connected but it won't charge.
When i open batterymonitor i see that the charger is connected, but the phone still use his battery.
I tried this with all kinds of charders and all kinds of micro usb cables. Then i thaught there was maybe a resistor or chip or something build in some chargers, because i couls only charge with chargers with 2 wire cables.
Then i took a usb extension cable and i disconnected the two data wires so only the + and - 5V cables were left,
but still no success. If anybody knows where the problem is, please let my know
with kind regards! Martijn

Galaxy S4 won't charge.

Help! My Samsung Galaxy S4 won't charge or connect to a computer. I've tried different chargers, cables, plug in locations, car, 110, computer. There is no dirt. Connection is clean. I have a spare battery and both of them will charge on the battery charger. I have tried backed up roms. I have done a factory reset.
All of this and nothing helped. Am willing to try anything. Verizon is going to send me a refurb.
Help please.

Is there any indication of a connection being made? If not, you should just wait for the refurb. If you have rooted, I really doubt Verizon will honor the warranty on the broken phone. I wish you the best.

sounds like contacts are on the phone side are damaged or the micro usb port is damaged.
Have you plugged into to a pc just to see if it can "see" the device and connect?
You stated it cannot connect to a pc, so i would suspect you have a bad micro usb port.
if you can connect, its not the port, and try taking an eraser and gently swabbing the contacts on the phone side.
also, make sure when you insert the battery there is an actual contact established. sometimes when pulling/pushing the battery in and out, those contacts sink further into the device and finally when you insert a batter the contact is very poor. you may need a tool or tweezer to just VERY, VERY GENTLY raise the contacts if they sunk in to far......but be careful not to pull too hard/much they can snap and you will probably void any warranty......

I am having the exact same problem. I have replaced the microUSB charging port on the phone and it still doesnt charge with the new port. I'm not sure what is going on. NEED HELP BIG TIME!!!
I'm having the same problem as well. It has been like that for bout a month or so now. I googled it and it seems to be a problem with the s3's and s4's. I'm not so worried about it as I have a spare battery charger and I have the wireless charging receiver on my s4 and it charges my phone just fine.
I had this exact problem I believe...tried several different chargers...everthing. Try turning the phone off and see if it takes a charge. When mine was off it would show a gray battery and vibrate every 5-10 seconds. I figured it was an issue with the charging/usb port but all of the sudden my phone started charging normally and is visible by a computer. Lasted for about 4 days and have been in the clear for about 3 days now. No clue what went wrong or why, but try what I mentioned above by charging with phone off for a half hour or so and see if it has charged at all. If you need a new USB port, not all GS4's have the same port, so you must get a verizon specific one (ebay). usually run about $20..or $65 installed at a phone fixing center. I didnt want to lose MDK, so I was prepared to just charge externally, but ended up not having to...yet
It happened to me also. I had some intermittent luck with blowing out the port with air from my air compressor. But in the end it just stopped working and Verizon sent me a refurbished one.
I Also have this problem!
PLEASE HELP!

Have you tried powering down your phone and seeing if that gray battery comes up and you get the vibrations (while plugged into charger)? You may need a new port, but since your under warranty, you could get a replacement unless you want to charge externally
S4 problem after update to 4.3
Hy,
I have a similar problem with my S4 (i9505), won't indicate if it is charging or connect to a computer, but while the charger is conected to S4, the battery level is increasing. When the battery is fully charged S4 is SHUTING DOWN!!!! And it wont start by pressing ON/OFF button, it will only start after I press Vol Down+Power, after goes to Download Mode and press Vol Down .
Tryed in many ways to fix:
- restore-
- hard reset
- changed te battery and charger
-i\ve changed even the usb port (flex cable) and =no results...
All problem started after update to 4.3.... and it is not an isolated case too many people complains about this 'awesome smartphone' with 'awesome issues' .
So, if anyone have any ideea how to solve this issues....
{Sorry for my bad english}
Had the same problem...lasted for about a day, I had to take a dry q-tip and clean the charger and the port where the phone charges and was able to get it working again. If you are rooted and are having issues go to amazon or ebay and get a wireless charger and it should take care of your problems as well

Ok....wireless charger...but what about syncing with the PC?
Now I have JB 4.3 , for a custom ROM I need to use usb cable to connect to PC, rigth?.
For me it is annoying, because I do not know for sure if this is caused by updatind to 4.3 or is a harware problem.
My wife's phone had this issue last night and this morning; charger or computer, it wouldn't charge. I turned it off, took out the battery, SIM and uSD card and put them all back in. After that it started charging again. I don't know if this will solve the problem long term, but so far it seems to have done the trick...

Lucky you...I did more than that, but no result in my case. I found on ''community.verizonwireless'' many more similar cases where ''customers support'' tried to avoid giving the answers for a real solution.
Well, our luck didn't hold. My wife's S4 wouldn't charge again last night. I tried another Samsung charger and a different cable but it wouldn't work either. When we left the house she tried it on the car charger and it worked great. Trying various other chargers we found that a kindle charger wouldn't work, but other third party chargers would. Even her PC USB port seems to work and she doesn't have the drivers loaded. For now she replaced the Samsung charger and cable that came with her phone for one that came as part of an accessory pack and it's happy again.
I have no idea what's going on with the thing. I asked one of the guys at the Samsung booth in Bestbuy and all he had to offer was reflashing the ROM or un-rooting it and doing a warranty exchange...

Can you check, please, if your new data cable has 4 or 5 pins(look to the side that connects to your phone )?
My first s4 done this. So I ended up with a replacement mdk phone after I figured out if you bend the lil piece in the charging port of your phone (not too much BTW) the charger will slide into the port as it's meant to.
Sorry I can't remember the tech term for that lil pin inside the charging port.

Just going to throw this out there....
I think the S4 is compatible with QI compliant wireless chargers. Amazon has some that are only $20... might be worth the purchase.... hell if I didn't have this tank of a case on I would buy it.

Thanks for your answer, but I already did that....I even changed the flex cable with charging port, no luck for me.....
I think this issue it is not hw problem because, look what I did today:
-I put a new Rom , so I used MIUI FOR I9505 from http://forum.xda-developers.com/showthread.php?t=2306650
And now it behaves even stranger:
S4 is ON and wall charger is conected, (LED IT IS OFF but BATTERY IS BLINKING and is charging ) after battery level go up to 100% and disconect the charger, the LED STARTS TO LIGHT GREEN!!!!
So, now shows that is charging when charger is NOT connected?
