[Q] USB Charge/Connection issue - Hardware Hacking General

Hey all,
I have a Galaxy Nexus which recently started to act up on his USB port saying it's constantly connecting /disconnecting to the charger with no cable present.
Device: Samsung Galaxy Nexus
Edition: Maguro GSM
OS: CM10.2 nightly + CM11 Alfa
Chargers: OEM, generic, battery & laptop
Cables: OEM & generic
Reproduceable: sometimes
This week I noticed my phone did not react immediately when I plugged it into the charger. Mostly after some fiddling (bending the cable away from the screen) it would start charging. After pulling the cable or removing the charger from the wall, it would generally take 5 to 10 sec for the phone to realize I pulled it- this used to be instantly.
Strangely, when the phone said it cannot charge it can be connected to a computer as Media Device without any problem. Charging only happens after the fiddling again.
Looking into BBS, it cannot give any stats because it says the device is connected constantly to a charger. Android original battery monitor stats are also a mess but it does not say I am connected always.
Every now and again the phone also starts making notifications as if he was constantly connecting and disconnecting - leading to frustrated looks of the people on my train...
Cleaned out the port - no success
Hit it on the train table - no success
Reset, battery pull, flash, different OS - no success
After this all I think it will be a hardware issue. Nothing seems bent and no pins seem to be sticking out. Removing the back and checking the mother board showed everything still intact and all connectors still in place.
I'm guessing now the micro USB connector of the phone has somewhere some corrosion or a pin out of place but not visible to the untrained eye.
Can someone shed some light please?

2 screenshots to show you what I mean.
No, I am not up for 9 hours and lost only 10%... Battery life has become horrible since this issue. It just thinks it's constantly hooked up to a power source and I think it's no longer power efficient because of this. I already disabled charge connection sound because it was driving me crazy ...
Please help if you know even half a solution. I can also post a photo of the connector but the problem is that there's not much to see there...

I think you have problem with charging circuit >>if you have solid knowledge in electronics you can simply replace it

replacing this port in attached pic will solve your problem .... otherwise you can fix your own port because I think one of your USB port pin are touching the ground chase of your motherbord

Thanks for the reply. Somewhat saw it coming I would have to replace something...
I already looked on some sites like ifixit to see what I could do but I thought to have seen that the Motherboard was in one big piece.
Could you please give me the website where you found this or the name /article code of this component?
Thank you

try to follow the steps on the link it is very helpful http://www.ifixit.com/Guide/Repairing+Samsung+Galaxy+Nexus+(Verizon+LTE)+Micro+USB+Charge+Port+%26+Main+Mic/9641
and you have nothing to do with the motherboard just take the old charging port and install the new one

Ordered a new part. Hopefully it'll work...

Troubleshooting - a500 won't charge - Is my power supply or tablet dead

As of last night my A500 will not charge. I left the device overnight and unfortunately now have Zero charge.
- My charger makes a noise, I think it always did, so I'm assuming the charger is OK.
Can anyone confirm that the chargers give off a kind of electrical buzz when working?
- I get no light at all on my A500. If the charger is OK I'm thinking something has gone within the tab, be that circuit or battery.
Any ideas or tips here?
- Sadly I do not have a multi-meter to test either the charger or the tab, no friends with a similar device, I've lost my proof or purchase (which is painful and rules out warranty), and am a bit stuck what to do.
Any ideas?
- I've heard/read that allowing the power to drop too low can cause a problem. Obviously Zero is bad in this case.
Can anyone confirm this rumour or suggest a fix?
- I did try entering recovery and resetting the battery stats - whether this made things worse or not is unclear - it certainly did not help.
ANY HELP OR IDEAS WELCOME (bear in mind that I have spent quite some time searching and trying other peoples' ideas already though.
Thanks,

Quit guessing and get the charger checked
In reply to myself and to help those with a similar issue.
Yes a charger my buzz when good OR bad. The trick to seeing whether it is working or not (aside from it charging the pad) is to see if it gets warm -- no warmth, probably broken.
As for measuring with a multimeter the trick is to insert a paper clip into the small hole in the plug and measure the voltage between the outer plug (negative) and the paperclip (linked to the positive). Few multimeters have pins that will fit inside the super tiny plug on the A500 charger so the paperclip is your way in - obviously be sure not to short circuit the thing!
There are many chargers available out there. In Australia Jay-Car and **** Smith both have perfect chargers, the correct type, voltage, amps etc, they even come with multiple pins -- sadly none fit the A500!
My solution was to go to Infinity who are a provider of Acer spare parts. They have the correct charger and are easy to deal with BUT -- It's not cheap! They want $40 for the charger and a further $30 for the little bit on the end that gives the plug its nationality. In most cases we do not need this though as we can reuse our old one, but hey, not cheap all the same.
Still, it works and I'd rather be ripped off than get the wrong thing and blow the mother board.
NOTE: if you do get a charger from anyone other than Acer or a supplier of theirs - be sure to match every detail of your current charger - especially polarity.
I had problems with charging on my A500. When I plugged in the charger the power button would turn orange for a few seconds and then start flashing white.
I took the back cover off and found that the wire to the centre pin of the power connector on the tablet had almost broken off. I touched it lightly and it came away. Re-soldering the wire fixed the problem, it now charges as expected.
After fixing it I measured the charge current. It starts at a small value for a few seconds and then jumps to full charge rate. It seems there was enough of a connection to handle the small current but as soon as it switched to full charge current the voltage drop across the remains of the connection was too much and charging stopped.
Charging problem
I too just experienced the no charging problem. I looked up how to open up the tablet and tried to trouble shoot the problem myself. My problem turned out to be a very easy fix. The Posative lead on the back of the charger port had come loose, a simple touch of the soldering iron and its fixed. I thought since I had it open I might as well go ahead and change the battery too since it was 4 years old. Its an old tablet and time to turn it into a hand me down for a lucky niece or nephew

[Q] Galaxy S4 won't charge

I should clarify the title by saying that trying to charge this phone is resulting in a number of odd results.
So firstly, I've tried using the wall-mounted AC charger. I then tried using USB on my computer, in 3 different usb ports. The phone was charging perfectly less than 24 hours before this problem began.
I plugged it in as per usual, and it didn't show the little lightning bolt on the batter icon like it should. It wasn't registering that it was plugged in. I tried plugging it into my PC, and it wasn't showing that it was connected via USB. In addition to that, my computer was failing to install the drivers for it. I went back to the AC charger, and tried a few different outlets, including one on a power strip. Nothing worked.
I searched online, and found that other people had this problem, and could only fix it by resetting to factory default settings. One person even had to do it twice to get it to work. So I did this, and it still didn't work. I tried charging my old phone with this Ac charger and cable, and it wouldn't work either. So I thought it must be a fault in the cable. So I dug up the cable (also micro-usb) for my old phone, and tried it. It worked just fine for my old phone, but my S4 still had the same problem, but with something new. It would say "Dock connected" but still not charge.
As of right now, it seems to be charging properly with my new AC mount and old usb cable, but I'm worried that this could happen again. Considering this seems to be a problem for other people too, what should I do about it? Is there some way to prevent this sort of thing from happening? Was it purely the other cable, given the fact that it didn't work with my old phone either? I'm on an extremely tight budget, and this phone is my only way of being contacted for job interviews, so having it in working order is very important. Any advice would be very appreciated!
Having exactly the same problem... couldn't find over the internet a solution yet or a position about it...
Affraid it's a hardware issue and have to send to the assistance...
Anyone know what to do?
Yup having the same issues - but i noticed only having charging issues when battery reaches 20% or the low battery notification pops up
it detects that a usb is connected but it wont charge
Solutions:
- dont let it go below 20 which is ****
- some people claim that if you use a 5pin charger instead of the 4pin which samsung includes solves the prob
Mine is a little more serious I think... haven't found a solution like that yet.
I have to connect/disconnect multiple times and it suddenly works.
But between those connects/disconnects it presents multiple problems, it appears on notification bar "Dock Connected", sometimes appears "Dock Connected" and on the notification bar appears "Suggested Apps (Anchoring)", other times it appears "Dock Connected" and the volume bar appears on the screen and stay there freeze (the phone works, but the bar doesn't disappear)... Sometimes the phone starts charging and suddenly stops, other times it says it's charging and if I remove the charger it keeps the charging symbol on the battery icon...
It's completely crazy, gonna take to service I guess.
Have you tried blowing out the usb connector on the phone with a can of compressed air?
If there is a minute piece of dust there it may be shorting something out - error that dock is connected. I know this happens to other phones, there was a big thread about it on the S3 forum. Might be a simple little thing like that...
Unfortunately that doesn't work for me, will send to service, let's see.
have you solved this problem and how?????

Yep, chalk up one more with the same problem!
At first I thought it had something to do with Aviate, a custom launcher from Yahoo (actually a pretty sweet one at that!)
But I guess not.
My work-around is to reboot the phone while connected. It charges fine while turned off and seems to keep charging when booting while plugged in.
Still... this is a stupid work-around and I want this fixed properly.
Any news from any of you guys?

Had this problem today. Suddenly out of nowhere "Dock is connected" message appeared after plugging the charger in and out. Tried to clean out the dock with stick and cotton on the edge. Then turned off and plugged in charger. Problem exists. Phone charges but stops regularly. It is very annoying when you dont know how to fix this kind of problem.
Any new solutions?
Right after this post, I froze the app "battery doctor 4.9.2" using Titanium Backup Pro (you can just uninstall it i guess). Then just plugged charger and now it's already Almost 90% without any interruption.

Amazing! I've dealing with this problem for weeks and internet didn't give me any good answer, but the whole problem was a baterry monitor apk that for some reason was interfiering with the charger. Thank you so much!
I had this problem too and in my case it was a hardware problem. When i start the charging it kept repeating the start proces of charging with the vibration and the grey battery icon(in case the phone was turned off). The battery icon with the green charging light just didn't showed up. I tried many things but nothing helped. I let the phone keep charging for the whole night but in the morning i saw that it didn't charged anyway!
Then i went to a local phone reparation shop(none official samsung) and they knew immediately recognized the problem and it was the usb/charging connector where you plug it in the phone. They fixed it in 1 hour for a cheap price and from then(i think a few months ago) it charges back perfectly. It seems it's a disease with S4's.
In my previous post I was happy thinking that all this charging problems were solved after uninstalling battery apk. But, in fact, my S4 charges very slowly after that incident. I have tried two other samsung adapters (galaxy s4 mini; grand prime). First one results the same (up to 5 hours charging), the latter was comparably shorter (up to 3 hours), but still slower than it used to be (2 hours normally). So I highly suspected the hardware might be the reason. Thank you for your information, now I will also have the phone checked at some local repair shop. And give feedback of course.

You probably got some water damage in your port. What you need to do is clean it. I used pure alcohol and a toothbrush for that. After that I flashed a custom kernel so I could enable fast charge true usb.
That's the reason your phone is charging slowly, it thinks it's connected true usb. So you need to boost the usb charging. After a few charge cycles I could revert back to my standard kernel and the problem was fixed.
I think ur right Lenny.
Mine S4 got wet last weekend and now i am also getting the " Dock is connected" message when i plug in the charger cable.
I can charge my phone but sometimes while charging i hear the sound go off and on what you hear when unplugging the charger.
I will try your solution and hope it will fix mine too. Thanks for posting ur tip!
I suggest you go buy a new genuine cable for an s4, the s4 does actually require a special cable capable of 2A charge rate otherwise you can end up in all sorts of bother.
Thank you all for sharing tips. I cleaned the port as suggested, then replaced my cable. Now everything is back to normal.

Same problem - galaxy s6
Hi there - same problem, on my 128gb s6. started this morning. Yesterday everything fine, would charge when connected via USB to both laptop and to regular samsung usb power unit. Have now tried 3 different USB cables including the samsung cable, 3 different usb power units and of course tried all 3 cables in laptop usb port. Have checked phone's usb port - clean as a whistle. Have rebooted both connected and unconnected. Started getting 'dock connected' message, now it just wont charge, although starts up fine. I take very good care of the phone, so no water damage or untoward shock damage (never get it wet, never drop it). Remaining battery charge seems to fluctuate between 30% and 40+ %, depending upon whether it's plugged in or not. If I turn it off, then connect usb cable, the phone just reboots, still not charging. I then turn it off and see no green battery charging screen, as I used to seen when connected but turned off. Should I just hard reset and take to repair shop? Still under warranty.
I would return the phone for a warranty repair. Software would not usually prevent the phone from charging when powered off.
As a final test, see if the s6 will charge wirelessly, assuming you have access to a qi charging pad and the s6 has a built-in qi receiver like the North American version of the s6.

Redmi Pro Charging port broken/shorted

Hi so I bought the device about 3 months ago and it was awesome from the get go everything was great until today when i plugged in my device for charging. After a while i noticed it was charging very slowly so i instinctively disconnected and reconnected the type a usb cable from the charger. On reconnecting there was no indication of charging on my phone. I reconnected it one more time and nothing. So i took out my voltmeter and connected that in series. The moment i connected it it started to restart continuously. On off on off and i had to disconnect it to make it stop. I thought it might be a cable issue so i tried a micro usb cable with an adapter. Same result. Then i switched chargers, again same result. Whenever i disconnected the phone it would stop restarting. On one charger it did stay on but the voltage dropped to 3 volts and amps up to 2.3.
So i have concluded from above stated facts that the charging port/ board is kaput. If anyone has any suggestions on this please let me know.
After this i started to search for a replacement type c charging board for the redmi pro but i cant find any. Any help in finding one with international shipping would be appreciated.
Please leave Ur thoughts on my conclusion.
replace your usb c cable
Thx. But luckily i was able to repair it. Woohoo
Anyone know where to get a replacement usb charging pcb ?
was it a easy fix or did you replace the usb board?

Sorry for the late reply. I searched for the port on various websites when i had the issue but couldnt find anyone who sold redmi pro parts. Luckily however i found a seller on ALIEXPRESS who said that he did have it. He had asked me to pay using mi max charging board which was around 7 usd and then he would send The redmi pro charging board.
Sadly i cant find the seller who said this so i cant share the link here.
What u could do is go on aliexpress, find the largeat stores with the widest variety of xiaomi charging boards and ask them if they have it.

For me it realy was an easy fix and fast one too.
I was out of option at the time so what i thought of was that if i could find a 4 or 5 amp usb brick i could probably melt the shorted portion of the circuit. Ofcourse that in itself is dangerous because it could ruin the phone completely.
Anyways sadly i could not find any such power bricks. When i had almost lost all hope i thought of trying this out in my cars charger because car is already running on a DC system and is capable of providing alot of current to the usb charger, which is just a sort of regulated stepdown transformer. So hopefully that would provide the power i need. I started the car and then connected the phone. The moment i connected the phone to the charger the cars rpm lowered slightly for a second as if it were under stress and then went back to idle. AND MAGIC! It was fixed.
What it did was provide alot of current to the phone which heated and melted the shorted circuit. Since then ive had no issue with the phone.
It might be different for u though so i wouldnt recommend just doing what i did. If u have waranty claim that. If u r out of all options and u feel like ur phone is a dead piece of metal (like i did) then go ahead. But do not hold the phone in ur hand or anything while doing so because it can be dangerous in a number of ways. DC is much more unforgiving then AC.
Hope this helps.

Charging port starting to break

Hi XDA,
After being a long time reader, it's time to ask you guys for some advice. My S7E still works great after 1.5 year of quite intensive usage. So far so good.
However, over the past couple of days, I've started to notice that my phone wasn't charged at all after putting it on the charger for 1-2 hours. The first 2 times I just thought that the cable just wasn't in properly, because after I reconnected the cable, it did charge. A few days later it just stopped charging at all. After testing it on a wireless charger of a coworker quickly, I knew the battery itself was fine. I tried a couple of cables, both new and old, but it wouldn't charge. Because I also used new cables, the cable wasn't the problem either.
So then, as a last resort, I tried to push the actual connection part (having the pins on it) within the port on the phone a bit inward. This so the pins in the port would better connect to the pins. And Boom! It started charging. So then I knew where my problem was. But now every time when it stops charging again, I have to do this over and over. This puts stress on the connector, and after repeating this process enough times, it will eventually break.
So here's my problem.. Because of how contracts are setup here, I can't open my phone up myself to simply replace the USB port (namely materials, but also certain skills). Also the repair service that is suppose to do the replacement, basically just sucks. They gave me a phone with a bend LCD back last time. I've fixed it myself afterwards back then. I don't want to send it there, except for screen repair.
So I'm looking for a way to either fix this connector permanently without opening my phone, or a specific type of cable focussed on bad connectors, or whatever might help me in this sitation.
Thanks for all your advices!

Thanks, but that's only part of the problem. Let's say I need to connect my phone somewhere on the fly for whatever reason. Or are maybe on an airplane or something like that. I'll always need to bring toothpicks to fix the port, up until it breaks.
Mine s7 edge just stopped fast charging one day and PC doesn't recognize the phone anymore. It's still charging slow though.

just use airdroid. can trasnfer files wirelessly.
Well, let me clarify a bit... I know there are workarounds for the issue I'm describing. I could setup SMB and transfer files through that. The heck - I could write my own app, using my own "protocol". Charging can be fixed through wireless charging, thetering can be fixed using the hotspot, adb can also be done wirelessly, and terminal access I could get through an app. I could continue for a while here.
I actually want to fix this specific problem under the given circumstances. Not just dozens of workarounds for specific tasks. Let's say I **** up flashing, and need Odin to restore my device.
there isn't a way to "fix" this without removing a LOT of small, fiddly bits inside the phone. You certainly could get a micro-usb extension cable an leave it plugged into the phone all the time, or MAYBE use a Mophie Juice pack (a battery pack in a case that has a micro usb that plugs into phone and a new port that is on the edge of the case...
Other than that...SOL...
No sorry you can't, its nearly impossible to replace usb port without opening front panel and screen, and there is not a single percent chance to prevent screen from damage when opening front panel and glass, its simply doesn't designed to be opened. Go to samsung care center and give them the fee to replace usb port, if your screen got damaged during repair, they will replace it themselves.

Kinda was afraid of that, thanks for confirming. I like the idea of the case, hadn't thought of that. But the idea of the extension cable got me thinking. I think I'm gonna order some of those magnetic USB cables. They have a small adapter that barely sticks out. Then I simply need a few cables, for work, home and on the road. Because the adapter has no reason on move, it should be alright.
Thanks for your suggestions everyone!

Le Eco Pro 3 suddenly wont charge

So I have been running AICP 13.0 for a couple weeks and love it. I woke up this morning and my phone didn't charge overnight despite being plugged in. It shows it is connected (the lighting bolt in the battery icon on the top right) but the led light doesnt display and it doesnt say charging. Other weird thing is everytime I plug the cord in the volumne starts adjusting itself up and down automatically and now sound is not working (microphone or speaker audio). Battery is now draining and I cant get it to charge. Any ideas why this could be? I have tried it with numerous cords and charging bricks, did a factory reset but still can't get it to work. I am now down to 20 percent battery life and am worried I have a hardware problem and am going to be without a phone for a couple days.
Anyone experience similar things or have ideas to try?
Also leeco doesnt have a us website anymore, so how do I contact them for support if needed?
Only idea a hardreset or clear coch?

Well, go back to any eUI vendor ROM (basically, stock) and see if it solves the issue. Preferably the same firmware version that your device was originally on. It could be a hardware issue or a software issue.
Sounds like a faulty charging port. You might need to replace yours. You can find replacement charging ports on Aliexpress, and a teardown here: http://www.myfixguide.com/manual/leeco-le-pro-3-teardown/ (the phone has the same internals as other LeEco phones, so you can consult various LeEco teardown videos too).
EDIT: now, I don't know if this will work for you, but freezing the phone for an hour might also get it to start charging again, but only do this as a last resort if it dies on you. And make sure you put it in a plastic bag first (obviously).
Ok I will locate the stock rom and flash it, I havent looked for it but it has to be on xda.
As far as replacing the charging port....I bought the phone in June so it should be under warranty correct? Does anyone know how we would get in touch with leeco support? Do we still have a warranty since they shut down operations in the US?
I still have 16 percent battery (I turned it off once I posted here so I could have juice to try ideas you guys would come up with, so hopefully I dont have to try the freezer trick.

Well, go back to any eUI vendor ROM (basically, stock) and see if it solves the issue. Preferably the same firmware version that your device was originally on. It could be a hardware issue or a software issue.
Sounds like a faulty charging port. You might need to replace yours. You can find replacement charging ports on Aliexpress, and a teardown here: http://www.myfixguide.com/manual/leeco-le-pro-3-teardown/ (the phone has the same internals as other LeEco phones, so you can consult various LeEco teardown videos too).
EDIT: now, I don't know if this will work for you, but freezing the phone for an hour might also get it to start charging again, but only do this as a last resort if it dies on you. And make sure you put it in a plastic bag first (obviously).

Have you tried a different lead? I've had one leeco lead go on me, i almost chucked the charger until i realised it was the lead
Ymm, often the cable is broken.
Yes I have tried numerous cables and chargers. It has to be a hardware issue as it is dead now and won't charge at all is my thinking. When I plug a charging cord in it displays several quick red led blinks where it usually has the yellow led for charging but nothing else. When I tried it with my car charger this morning it got really hot very quickly.

Sadly, the stock charger cable is known to destroy the charge port. If you have always used the stock charger cable, then that is probably what caused the issue . I had to get my phone replaced for that reason about a year ago. If you do end up getting it fixed, get a certified USB-C cable and scrap the one that came with the phone. So sorry man...you shouldn't have to deal with this.
