[Galaxy S II Q&A, Help & Troubleshooting] oklono:
Hi guys, i have tried replacing the replacement USB Port but the problem still persists. i received my package from parts4repair last night. the repair took less than 10 min to complete. The problem was resolved for the night however resurfaced this morning. i launched my BetterBatteryStats (BBS) this morning and realize the phone still recognizes itself being connected to a power source (pls see picture attached).

To clarify, the phone was not exposed to any form of moisture. I live in Singapore, an all year summer country hence the chances of condensed moisture in the phone is low. Thus i doubt the issue was caused by water damage in the phone.

The phone is current running 4.1.2, NeatROM, Syria kernel. When the ghost charge problem first surfaced in Mar 13, i did a full wipe and re-flashed the stock ROM for the phone, however the problem still persist. so i presume the issue is not caused by software.

I believe the problem lies in the charger i use for charging my phone. 1st cut, i am using a 3rd party usb-ac adapter. 2nd cut, i am using a 3rd party usb cable. i suspect that the poor quality of these two have lead to certain power leakage in the main motherboard of the phone. i have purchased a new set of replacement USB Port and hopefully this time i can successfully pin point the cause of the issue.

Meanwhile, i would appreciate any help you guys can offer on resolving this issue.

I'd try with a genuine Samsung usb cable and charger first of all, it often solves unpredictable issues... try the new 2000mA/h Samsung chargers for galaxy s3/note2, they work great with the S2 as well and cut down the charging time by a 2.5 (ish) factor. ;)

---------- Post added at 12:11 PM ---------- Previous post was at 11:54 AM ----------

[/COLOR]oh, and stay off batteries sold for a bargain price too.. a few months back I bought 2 more spares, genuine samsung 1650mA/h for i9100 for like 5$ apiece.

Turned out they were from a faulty batch, the phone powered up but would do all kinds of crazy and unpredictable things (too numerous to remember them all), in mine and the i9100P of a girlfriend of mine... whereas 'noname' 1800mA/h batteries bought from the same site for the more regular price of 10$ each behaved perfectly. go figure :/

HAKANN, plazzTT and everybody else plagued with weird charging issues try it (changing charger + cable for a genuine one). If it don't work upgrade to the latest stock unrooted ROM (I noticed one of you's on KG2, c'm'on this is like 2yrs old now !!), new ROMs often implement fixes for such bugs. And go for a full factory reset, SD card format internal & external.. I've had some issues like that in the past, they were probably caused by the outdated ROM, a short in the on/off switch I accidentally discovered when opening up my phone, and/or corrupted files on the flash memory that the media scanner kept stumbling on and looping on forever, draining a full battery in less than an hour, or a combination of all of these factors...

if the issue still persists after that, I guess your only option is an RMA or mainboard replacement.. :/
[Galaxy S II Q&A, Help & Troubleshooting] spark001uk:
I would exercise caution there if I were you, charging at a higher rate than the battery was designed for can damage/overheat it (or worse). It'll almost certainly decrease its longevity anyway.
[Galaxy S II Q&A, Help & Troubleshooting] Snakeforhire:
Perhaps. All I know's that I been doing this for more than 6 months (ever since I got my Note2) on a panel of 8 different batteries (aged from a few months to almost 2 yrs now), and haven't noticed anything different as far as battery life goes, not more than the usual average capacity loss of 10% a year or so..

Funnily, it's the ones which get charged on the 2A/H charger which seem to last the longest, those I charge on USB tend to last much less (but the difference is consistent and reproductible).

My guess is that this is another urban legend about Li-ion batteries. And for the like 10$ it costs me to buy a new one, the benefit in charging time far outweighs any possible increased (but probably negligible) wear on it..

---------- Post added at 01:42 AM ---------- Previous post was at 01:28 AM ----------

Seriously hope you're kidding here m8... OK, you can happen on some weak or faulty batch, but once you pick one that works flawless, that phone is damn near indestructibl. It has survived each offense and abuse I've (unvolontarily) thrown at it during the past 2 years (and trust me, when it comes to stress-testing some hardware, I'm the über-proof of indestructibility.. If something survives me in my daily life for 3 months, you can throw it out on the market and sleep soundly, no angry customer is going to come complain to you anytime soon), and only needed two parts replaced : the very same PCB that worries you with the usb plug (ok granted, this one isn't very tough, if you let it fall a few times on the floor or sit on it while plugged in. But c'm'on it's a 10$ spare part to screw in, a child of 10 could do it one-handed) and the power button/PCB (this one's a bit tougher to replace, with 3 very fine solder point to replace), (plus a full rebodiying, but that was just for vanity's sake), that's it..

I fixed my - "charging Problem" with a USB board swap

Hi there,

Thought I'd maybe add my two bits worth here. I am another who solved the issue with a USB board swap.

I had tried all the usually cleaning and such, none worked for me....

Here is how I fixed my Galaxy S2:

"techmaester.blogspot.ca/p/repair.html"
[Galaxy S II Q&A, Help & Troubleshooting] rothariger:
Yeap changing the port is the best fix every, and really easy to do it.
[Galaxy S II Q&A, Help & Troubleshooting] Mike Post:
It sure seemed that way.

My brother's i9100's charger port wasn't working after some water damage, so I ordered one from eBay for about 10$.

The replacement seemed really easy. I used the video noted below as a reference.

I installed the new charger port flex cable without problems and now it's not turning on. There were no mistakes, no obstacles, I made sure I got rid of any static electricity before installing the flex cable or touching the motherboard, etc.

There's just no sign of life whatsoever. I've tried plugging it in the computer, I've tried swapping to a fully charged battery.

I figured that if the screen's not working anymore, that I'd still feel the vibration when it's turning on.

Any help?

There are 3 different versions of the board (denoted by the 'REV' number) did you get the right one?
[Galaxy S II Q&A, Help & Troubleshooting] Mike Post:
Yep, I noticed that straight away. REV2.2 and it matches the original part.
[Galaxy S II Q&A, Help & Troubleshooting] Mike Post:
Update: I've put the original usb port + flex cable back in. The phone is still 'dead' .. anyone have a suggestion?
[Galaxy S II Q&A, Help & Troubleshooting] val_net:
This solved the same problem with me. Thanks! :o
[Galaxy S II Q&A, Help & Troubleshooting] PJK2011:
I have a related but different problem. The phone will charge when the battery is not fully discharged. Once the battery is dead, it will not accept a charge when a charger is plugged in (tried various). This is a fairly new battery, being installed within the past few months. It will accept a charge when I remove the battery and put it back in. A Google search finds some people reporting this issue, but none has a fix. Most say to wait 10 seconds before replacing the battery, but I find I do not have to wait at all. Simply breaking contact and re-inserting is sufficient. I also noticed that removing the battery very long loses the date and time because Google Play Services complains about it. I wondered if this could mean it is an issue related to the BAT500 mainboard battery getting weak. I am running the CM-11 KitKat ROM.

Thanks.

Samsung Galaxy J 6

Hi I have a similar problem along with a vibrating buzzer while plugged in, what advice were you given?:confused:
[Galaxy S II Q&A, Help & Troubleshooting] KimFrederiksen:
Same problem

I have the exact same problems:

1)Activation of CARD mode - automatically.

2)Charging automatically- though charger is not connected

3)Enabling the voice mode - automatically.

4)Battery draining problem.

5)auto handsfree speaker enabling

6)phone switches on again, when I turn it of

Yesterday I went to get the phone serviced, and I got the main board swapped. And still the pesky problem persists! The USB connector is located on its own little PCB, connected to the mainboard, so I guess that must be the culprit. I have tried resetting the phone to factory defaults before, but to no avail. The Phone is running baseband version i9100XXKE7.

Later this week I'll attempt to change the USB-PCB.

Kind regards,

Kim Frederiksen

charging port problem

Dear all,

I have the same problem. With the extra annoyance that the phone keeps ringing and vibrating. It happens when i pull out the charger. If i shut down the phone, it starts itself up for no reason and starts ringing and vibrating again. How annoying is that. I want the phone to shut up. It isn't even rooted or anything. I have a Brodit carholder mounted on the triple clamp of my motorcycle, and the original samsung docking station that i use for the phone. Pulling out the battery is not enough. I have to do a factory reset everytime this happens. The first time it happened i couldn't find a topic that discussed this problem. Now I'm so fed up with this phone.

Is there anyone with the same problem?

Same issues here!

hi guys,

woke up this morning to my phone doing similar things. I doubt its software.

Unplugged my phone from charger and it was flashing charging symbol every 1 second. Shut phoned down removed battery and the put battery in and the Temp battery symbol and charge symbol flashed.

Phone randomly turned itself on too!

I then plugged in the charger, it settled down for about 3 hours then started up again!

I have contacted warranty about this problem.

Keep us posted. I am not impressed with this issue. I am concerned that because its intermitent i will not fault for phone techs!
[Galaxy S II Q&A, Help & Troubleshooting] xCaptainx:
I'm having a lot of issues everyone here is having. Looking forward to hearing updates from your repair requests.

Unfortunately my usb is not working, so I'm unable to resort back to standard ROM! am hoping my warranty will still cover this :S
[Galaxy S II Q&A, Help & Troubleshooting] mredfern79:
I had similar issues I would plug the phone and charge whilst using say playing games or watching movies. The phone would get hot and still drain.

I rarely use the usb lead but gave it a go and no problems.

After a few days i managed to figure it was the mains charger supplied with the phone. I now use my kindle charger or my wifes htc charger with no problems.

Basically, first you need to clean the USB port (take the battery out when you do this).

If it doesn't help, then maybe you accidentally bended USB pcb. It would happen if you accidentally connected USB cable upside down. In this case you need to bend USB pcb downwards carefully. The gap between USB pcb and socket bottom should be about 0.5 millimeter (about 2 millimeters on the top).

Got phone back, they firmwared phone back from KE7 to KE2 and it hasn't faulted yet. Will keep you posted. I doubt its a firmware issues though, mainly because it does it when phone is off too. Thoughts about Firmware vs Hardware fault?

I can confirm my SGSII has been fine since I changed the charging port PCB. Its not a difficult procedure but is a bit fiddly so big table, well lit and some tiny screwdrivers are a must! I got my part from parts4ipods.com for 7GBP and also some soft plastic ipod opening tools to help split the case open without damaging it.

I have a good mind to send the faulty PCB back to samsung and tell them I have fixed it myself after their authorised repairers failed to fix the fault - however I think they might say you have just invalidated your warranty :D

I'm after a charge port to swap mine out cause it's unusable now.

The thing that concerns me is the difference in the ones on ebay.

Most of them don't have the rubber microphone I have noticed (does that just slip on/off)? and also, on the right hand side, to the above the USB port, my board has the bottom component missing, not soldered in whereas some of the ebay ones have a component there.

Unfortunately parts4ipods is out of stock so I can't get it there (i'm in UK) so need to find another reliable source.

I can't be bothered sending it to Vodafone and waiting weeks for them to **** around with it.

I bought one and ended up sending it back, it was from parts4ipods

When I inspected it, it turned out the ESD protection chip for the USB port wasn't actually on the board I ordered, it was an older Rev1.5A where as the one in my device is a Rev2.2.

Now, as an Electronic Engineer, my better judgement prevents me from installing a piece of older revision hardware that has its protection circuitry missing in a multi hundred pound device that was damaged due to the usb pins being shorted.

I have another one arriving from Hong Kong some time in the next month, ods are that'll be no better.

Don't worry mate, I'll keep an eye out and if I get hold of a Rev2.2 I'll let you guys know. The other option is to buy the chip and solder it on yourselves but it's some micro solder work that you don't want to try unless you're a pro.
[Galaxy S II Q&A, Help & Troubleshooting] cchant:
I installed the older revision into my phone, and at first it seemed to work just fine. But after charging it, the phone starter going haywire. It would go into car mode, then desk mode then undocked rapidly, and would show that it was charging. I took it out and put the old one in and it quit docking and undocking, but would still show it was charging, but it was doing that anyway. So it appears that they are not interchangeable
[Galaxy S II Q&A, Help & Troubleshooting] alias_neo:
That's strange, they should be interchangeable, the circuitry on there is minimal and the only thing that is missing is the ESD protection chip, it uses a single diode in its place on the Rev1.5A.
