Replace the usb port circuit.

Try Bending the micro USB at different angles, try your luck.
This is a temporary solution.
You must rush to Xiaomi's service center. Or you may buy some usb circuit board and replace it yourself. that would me much faster. :laugh:

Very weird charging issue with my Samsung Galaxy S2

My Samsung Galaxy S2 has this problem.
A: I doesn't register the charge in the socket unless I wiggle it around or put pressure on a certain area. It's sensitive and it takes me a while to make it 'stick'.
b: It only charges to about 30% and then it stops charging.
I have tried numerous chargers and usb cables and always the same issue. I have replaced the battery and its the same problem.
Any help? I bought this damn thing on ebay a few weeks ago so I don't really know its history. The seller refuses to refund and I've opened a case.
Anyway that will all take a long time.
Any idea what the problem is and how to fix it?

Try Charging the battery externally using a battery charger, and not from inside the phone....I suppose it should get charged 100%...
If not then its battery problem...
If it does get charged then there might be a problem in the port or connection to the battery via inside the phone...get it checked at a samsung customer care...If you have warranty you might get it fixed for free...
I don't think there should be any problem with your kernel etc..
Press Thanx If I helped..
Try cleaning the micro USB port with a toothbrush or something similar
This type of issue is not weird and has been discussed on forum plenty of times.
Clean the battery contacts on battery and pins on device with alcohol (cleaning alcohol). If that doesnt work and you have changed charger/battery then your hardware is faulty so nobody here can help.

I tried with an electric toothbrush. no joy. Do you mean opening up the phone and cleaning it from the inside?
This replacement part?
Hi is this the part that you would replace?
NEW GENUINE SAMSUNG S2 i9100 GALAXY INNER USB CHARGING PORT MIC FLEX PART

if you need new charging port look on amazon or other type retailer i got one for £10 (uk).... then look on youtube for guide on how to fit part.. it looks tricky but its dead simple to do so long as you don't attack it like an ape.

[Q] Galaxy S3 (i9300) won't charge

So I got this strange problem where my phone stopped charging. I tried diffrent cables, adapters, charging it while being off, charging it via the computer and even tried to adjust the little lip in the micro usb port. Is the charging board dead? If it is, will a replacement be expensive?
Sent from my Galaxy Nexus using XDA Free mobile app
Well dude I think your assumption is right.
It might be the charging circuit only which may be dead.
Because as you told that you have tried diffrent cabels and chargers but still your charging is not working which means that the usb micro port through which we charge and connect our phone to computer is damaged and should be replaced .
There are many possible reason of damaging usb port like you may have drop your phone or by using faulty cabels and chargers or if u have rooted your phone then there is possibility of changing the voltage of current to more than 1000 Mhz etc etc.
You should try to flashed a complete stock rom by downloading from sammobile or directly using kies to update or re-flash your phone
you can try that may it may help you.

Nah, it won't turn on because the battery is empty.. I don't have a spare so it seems buying a new board is my only hope..
I saw there are loads of micro usb connectors on ebay. If I solder a new one on. Might that help?

You can try micro usb port which is available on ebay but it would be extremely very dangerous until and unless you know what you are doing.
My suggestion is to give your phone to the samsung care and tell then to repair it.
If your phone is in warranty then they will do it for free. You just need to provide them a copy of bill at the time you purchased s3.
Press THANKS if I helped you

[Q] USB charging not working, data connection working

I have found the Xperia Z2 to be an extremely slippery phone and it dropped to the floor quite a few times already, but the last fall seems to have finally damaged it. Now, when I connect it through USB to either a PC or power outlet, it will no longer charge. I can exchange data with my PC, view the external storage etc. just fine, but the charging icon will keep appearing and disappearing irregularly, about once per second. Meanwhile the battery gets drained instead of charged.
I now charge my phone through the magnetic port one the side of the phone, which is working fine. I would like, however, to know if there is a way to repair the USB port of my phone.
Many thanks

Seems like hard to repair. You would need to disassemble the whole device. I'd suggest you send the phone for warranty repair. Just do not mention you let it fall

Look into the Z2 disassembling videos, but I guess you should bring the device into a professional phones repair service.
@MrTheMan I think I know what bricked your USB port. The damage wasn't from the fall, you just connected the Magnetic charging cable upside down... Didn't you?
If you keep tightly in some points, dies it charge then? If not and still charges intermediate then there are two things. Either one of the lines if the port is damaged or the battery is of center. Remove and reconnect. First clean it's contacts with.a brush and pure alcohol. Do the same on the port.
Mine does the opposite, USB is fine(as long as I disconnect at 100% and don't charge with MHL adapter) but magnetic has the issue.

Hi,
I did connect my magnetic charging cable upside down. And my magnetic port is messed up now. It keeps charging and discharging when connected. It doesn't charge from a USB port and i need to plug in the adapter to a wall outlet for it to charge.
Is there anything i can do to fix this?

If I remember correctly there is one diode on the PCB that get's damaged :/
I have the same problem, due to magnetic charger..
Surely this is covered by warranty? I'm still under warranty so I will try to get a replacement.
How could they design it so poorly that it can be damaged like this....

Oh, I search some info. The diode just allow electric current pass one direction only. No wonder my XZ2 keep restart after I pressed shutdown because the diode allow the electric current from battery can pass through in opppsite way.
I don't believe it is a hardware problem. You dropped the phone but the USB port is not likely to be physically damaged by a knock. I had the same problem, on a Z2 provided by my company. I have requested a change, got a new one and in a few days the second handset had the same issue too. Two phones, both new, both never dropped, used with maximum care, both with the same problem. The second one wasn't even charged more than a couple of times before failure. And I had tried it as soon as I had it in my hands, just to be sure it worked, and it did, at first. I connected it to a laptop thru USB port (3.0) and it charged. Then updated apps and system to Lollipop, connected it again and it failed. In a couple of days. I'm sure nothing physical happened, unless my USB port fried it. Notice however, that data connection is working perfectly and everything else I connecrt to that port works as well.
I have some mag chargers too, and I don't believe I've ever connected them upside down. The plug is made in such a way the it does not connect if reversed, having one contact circular shape and the other elliptical.
I checked on the Web and there is a number of Z2 owners complaining for the same issue: there's even a video on Youtube showing this exact behavior. Sony seems to ignore it.
I must admit, however, that I'm unable to explain why a factory reset does not solve the problem. Now I'm trying to flash a stock ROM (mine is branded Telecom Italia) and see what happens.

Did you repaired your device. Please relpy this
Phone 2 years.
1. Charged through the USB port on the network 220 (native charger):
It reaches 81-83% of charge and starts to go crazy: flashing red LED charging and says that is / is not going to charge.
In fact, no charges.
I tried different cords and chargers - so everywhere is going crazy with a 80% interest
2. Charged via USB from the cigarette lighter in your car or the external battery:
It's okay - safely charged up to 100%
3. Charged through the magnetic cable:
It's okay - safely charged up to 100%
These are symptoms of what is dying?
Thank you!

Charging issues

Hello, I searched on other threads but couldn't find a good solution,I have 2 issues related to charging.
1. I need to plug the usb ( no matter what usb it is ) around until I see the message "Charging",then if I move it even a bit it stops charging and I have to plug it around the port again.
2. When it's "Charging.." sometimes it's 10% in 3 hours,sometimes it charges like 10% in maximum 15 minutes,my old samsung charger charges my phone extremely slowly ( max 20% in 10 hours ) compared to my father's charger with a better usb ( it can go up to 100% if it's in the "right position" in 8 hours )
I have 2 batteries,each has the same problem,as far as I see there is a problem with my charging port and probably I need a new charger with USB 3.0,should I get a galaxy s5 one? And how can I clean the microusb port? I don't think it's really 100% broken because if I'm lucky and it's in an optimal "adjustment" ( the usb cable from the charger ) it charges pretty well. Can it have some debris in it? If so how can I clean it? Also I'm pretty bad at following instructions on youtube so changing the microusb port myself with would be pretty tough with all that stuff,so I want to try to clean it first.
Thanks a lot for your help I have had this issue for a while and i'd appreciate any advice. :fingers-crossed:
By the way I use the outlet
1. Replace the USB port 2. Replace the batteries.
Search and read for many posts on how to clean the port, but it might be the motherboard is faulty.

i have cleaned the port,issue remains. Isn't replacing the USB port pretty hard for someone with no experience in such thing? Could I try replacing the safety pins or anything like that before going as far as replacing the port?
Pay for a repair, if you try yourself you'll just brick the phone.

Moisture Sensor issue S9 plus

It has been an year since I am facing the issue of moisture detected. There is no moisture inside the port. This issue occurred last year and is still here. The only temporary solution I found was to turn off device and plug the charge in 3 to 4 time and it starts charging its an temporary fix and I have to turn device off each time. Also due to this issue the device sometimes stop fast charging. I wanted to ask that will installing a custom rom (stock android instead of samsung rom) will fix issue (will this stop the moisture issue). Or is there any other way to fix it using root or without root. The guides on net about cleaning port or changing charger didnt work.

I am using orignal charger & cable also tried a different charger and cable. Its been an year since it started. For me I think the sensor is faulty. Also the charging changes to cable charging after connecting charger , same with all the chargers I tried.
Make sure the port is spotless; debris in the jack port can cause this. A toothbrush and a little anhydrous isopropyl alcohol can be used to gently clean it. Allow to dry completely.
Then clear the system cache.
Maybe a charger port PCB failure, a guess.

No idea. So you can flash it? WTF?
That means most of the mobo if not all is working.
No beep when you connect charger?
Display failure?
Port pcb failure? This little bugger can do some bizarre things on the 10+ if it fails or is the wrong one, so I learned.
Unfortunately I have no clue how to decisively troubleshoot this.
Hopefully someone here does.
My problem is solve no moisture deduct i change cable and factor reset now problem not there. When this proble happened my phone not charge faster charge sometimes so i use stock cable then fast charging show issue withe the cable now 1month there is no problem try and tell me guys.

For me factory resetting or changing charger and cable didn't worked. Still getting moisture detected but if i connect it when powered off after 2 or 3 tries it starts cable charging. But after unplugging charger and reconnecting after a little time it again shows the error.

Is it possible the phone has water internally?
Get some anhydrous isopropyl and carefully clean the c port contacts. An old toothbrush works if the bristles are long enough.
Allow to completely dry.
It may have a bad c port pcb or mobo if this persists... a guess on my part.

If you have root access.
There are members here that know the files you're looking for.
I'm wondering if replacing the charging port PCB would fix this. It's possible that corrosion from previous moisture exposure caused corrosion that left conductive pathways that are causing the error. Or the PCB failed.
These boards tend to be cheap, just get the right version for your variant. If the battery needs replacing then be a good time.
