Hey guys, I've done some searching and I'm still not entirely sure. The problem is that my phone can connect to my computer and is able to transfer files just fine but it will either never charge or charge extremely slowly (1%/2hours). Same thing happens with the wall charger and various other cables/adapters. I've already went back to stock and did a full wipe. The Galaxy Charging Current app does not work for me at all (only displays current_avg: 0). I'm planning to get my micro usb port replaced but I was wondering what are your thoughts on this.

I had the same issue with my S3. I happened to have a playbook charger around that chargerd it perfectly. It required a higher amperage than what the stock charger was providing. No amount of wiping, or flashing anything was fixing it. it was a hardware issue and i'm gonna guess that yours is too. Try another charger before going the replace micro route. An old moto charger that I had also worked. anything at about 2 amp did. The micro port is soldered to the board and the idea of having someone cut it off and re attaching it properly scared me.

Hey guys.
first of all i am using rooted GN2 N7100.
ive been rooted for about more than 6 months, with stock roms. but this recent few weeks. my phone wont easily charge via AC adapter. i thought it was the adapter fault. the symptom is, a 1 second repeated gap of connect/disconnect when plugging in the adapter. and it will stop for a few minutes. and it will continue that way again and again. so ive made some test. tested that ive made are as below:
1. Tested the adapter with other phone. it works fine.
2. try to change the cable but with the same adapter, still wont work
3. try to change the adapter but with the same cable, still wont work.
so.. i thought at 1st it was the microUSB port for SURE!!! but im proven wrong when i desperately need to make my phone stays alive, i try to plug in the cable to PC USB port!! WALLA!!! it work just fine!!!!
so i thought it must be the software.. so i decided to flash a custom roms.. was hoping that it will replace the system files to a new one and making the charging works. after ive done that. it still wont charge.. and restore back to my backed up stock roms because i dont want to deal with all the "EFS" hanky panky thing.
so now im out of idea. (u know how pain it is to wait for ur phone to charge on PC USB right guys? )
by the way. i found out something, if i use a cable that is not capable on transferring data and connect it to the adapter and to my phone. it works just fine!!! what does this means?
i need all u pros out there to guide me on this. tried to google this case in 2 days aready. so i think, my case is one of a kind for note 2.
Because of my phone will charge normally using PC USB but not in AC Adapter. so i really believe my MicroUSB port is still in good condition.
i hope that im not wrong.
just please help... thousand thanks,
anyone? please..................

Ur problem is unique 4 sure. R u on 4.3 or 4.4?
U can check if an AC Adaptor+cable of other Note2 phones work?
If it does, buy new one.
If not, mUSB port could be a problem. U said it charges on PC. That is DC current not AC. Which suggests that your port is working partially. It is receptive to DC not AC.

Something seems to be wrong with my charging port, lately its been charging at a slower rate and at times when I use my phone while charging, the percentage actually drops. I am using the standard OEM charger and also once in awhile it wouldn't charge and I would either have to fiddle with the plug or restart my phone. Anyone know what the issue is?

Some basic stuff, just to eliminate the usual suspects before going any further:
1. Have you tried another USB cable?
2. Have you tried another charger?
3. Have you tried another USB cable AND another charger?
Of course, it may indeed be a problem with the port on the phone. But in my experience, USB cable is the most typical reason for weird things going on with charging, as well as data transfer...

Yes, I've probably tried over 5 different usb cables and chargers from friends and around my house, still the same problem. I'm thinking it may be the port.
So far, in the past months or so, my phone started acting up with the charging, then my battery died and could not power up my phone unless charged, replace the battery, charging issue was still there and now recently charging slower plus my microphone is dead. I wonder if how hard would it be to replace to port. Trying to prolong this phone until Z4 is out.
Hi I bought my Nexus 7 2013 used in February. It came with a 3rd party charger and usb cable. It’s worked fine since I got it and it use to charge fine. I would use different usb cables and they would all work. Within the past 2 weeks or so it has become increasingly hard to charge it. Also this started happening on the stock 4.4.4 rom with root enabled. Today I installed a custom chroma 5.1.1 rom just to see if anything changed but it’s the same result it doesn't charge. The chroma rom says it has the Franco Kernel. Not really sure what that means but the stock rom's kernal wasn't changed.
I've left it off and connected charging to the AC for hours and would turn it on and it would have not raised at all in battery charge percentage. When it’s on and I can better see the percentage in this battery app I have installed I noticed if I jiggle the cable at all it will disconnect and connect again. So it might not be making good contact. It does this with every usb cable I have tried on it. However when I don’t move it and have it charging in sleep mode it does see it as connected and it says charging in the battery monitor widget app when I wake it, but it doesn't charge stays at the same percentage or lowers.
There is sometimes where I get lucky and it starts charging but it’s becoming increasingly tougher to get that to happen. I haven’t had any luck since last night messing around with it with different cables. I've even tried charging it on my PC but it’s the same result. It says charging but it doesn't charge. However if I do connect it to the PC I can view the files on the Nexus 7 fine as long as I don’t move the Nexus 7 much. I've also tried the AC adapter on my phone to see if it works and it works fine and charges. I've tried a kindle fire 9w charger on the Nexus 7 and that doesn't charge either.
Any idea what’s the problem? If I buy the official AC charger do you think it would work? Am I better off buying a Qi wifi charger? I rather not waste money on the AC charger if there is a good possibility of it not working.
Hi,
I seem to have the same problem recently. I am running on 20150519 CM12.1 nightly right now but this problem started to occur about 2 weeks ago i.e. with an older nightly version running...
It really feels like the USB connector is broken. I have to move it the same way headphones jack has to be moved when it is broken. Have you tried more different chargers? I did but no solution.... Now I got it luckily charged to 90% and I am making a quick backup.
Do you have still warranty? I technically do but would need to get back to stock and lock the bootloader back.
I found threads on how to get back to stock via USB connection but is it possible to lock the bootloader without being able to connect USB to computer?
No unfortunately I have no warranty since its a used item. I tried the 3rd party cheap charger, amazon kindle fire charger and my phone charger on it they all don't charge. I think you can replace the USB board on it but that would require opening it up and doing the repairs yourself. I think I will just get a Qi charger and see if that works. I kinda don't want to spend money on that just to find out its my battery that doesn't work. I am not sure what the problem is since I can connect the nexus 7 to my PC and it will see it and its files fine. So I know the USB port works at least a little bit.
It's a sub-board (usb-sim-touch module) issue. I would reccommend using a wireless charger as a quick fix since the wireless charger module is located on the motherboard itself so you should be good.
I may have a few sub-boards for the 2013 lying around but i'm not sure if they're 100% okay - as in calibrated, tested and fully functional. Also, i'd need to know if yours has LTE or not.
I have a Nexus 7 2013 32gb wifi edition. Thanks for the info. I put in an order for one of those wireless chargers.

perhaps you did that already, but from experience i must say that in 9 out of 10 cases it's the cable and 8 out of 10 cables are mediocre as compared to how it could be. no why i say that ist because i tested something between 50 and 60 cables during the last 2 years because i had similar issues and bought a special ampere and voltmeter with with the correct usb ports to measure the flow, same device, same power source, thus as empiric as possible result most cables charged between 0.9 and 1.1 A while about 10% were half of that and only few charged at 1.5A while 3 charged at between 1.9 and 2.1A. understand me right, same device, same charger, sam place all same condition, in car, on motorbike, on wall plugs. only significant difference were the cables. so check those first before taking more costly path which then only remain workarounds.
BTW amongst the bad ones were many that came out of the box with the devices and from different oems but many samsung original cables.
what i did i painted the ends of each cable with red for bad, yellow for ok, green for good and the outstanding ones already had a color, it were the stock cables from the oneplus one which had the best charging rate. good luck
Last weekend my phone was working perfect then the battery reached 1% i put it to charge and i saw that it was charging but it said 6 hours to charge, which i found strange, i tried multiple chargers, etc. and none of them worked, so i thought that maybe the usb port got damaged because the same thing happened to my old note 4 and i fixed it replacing the usb port but i changed the usb port and it didn't work, so i thought that maybe the replacement was broken too, and i order 2 more from different places, and they didn't work. So I think that maybe is a software issue, I have the OF8 room rooted with AOU Kernel and TWRP and using the engineering sboot but there is no way for me to flash to stock because the phone is not being recognized by the computer as a usb device, so when i connect it to the computer is only working for cable charging. What do you guys think? Maybe i got all the replacement port broken, or maybe the sboot is affecting the port, or worst case scenario, the mainboard is faulty (which i don't think so, because the wifi, bluetooth, gps, screen rotation, everything else works)
Computer USB ports generally cannot fast charge unless it's USB 3.0. The phone doesn't need to be recognized by the OS. Fast charging is different from quick charge, where you will need to buy a compatible charger.
Thank you for replying back. But the issue is not the fast charging with the USB computer, is with any kind of fast charge/quick charge wall adapter. I think that i found the issue, and it was an external battery pack that it was damaging usb ports, because i got a brand new LG G4 and after i connected it to the battery it started to behave in the same way, so looks like the usb port gets broken every time i connect a device to that external battery.
I have a problem with my note 8.0 for about a month. One time it's charging just fine, the other time it doesn't charge at all... The same with connecting with computer via USB. No matter what cable/charger i use. Suprisingly i can flash it, with no problem and i can connect USB stick via OTG anytime. I also tried opening it and removing battery for several hours, but that only worked once. Anyone has any idea what can i do next to solve this problem?
I use an app called Galaxy Charging Current. It enables you to get a rough idea of what the current of your device is drawing:
https://play.google.com/store/apps/details?id=com.abmantis.galaxychargingcurrent.free
For a Galaxy Note 8, it should be around 2 Amps, or 2000 mA, but it's likely to be around 1.7ish. I also use a device like this: http://amzn.eu/9aHm97o which you can also use to check current draw and test cables.
Not much help, but it may help you find out whether the device is taking a charge, or if there's a fault with a cable or charger.

After time the USB port gets loose around its connector, and does not hold the cable end tightly. Try replacement USB port. They are cheap and easy to replace.
Another thing is some aftermarket USB cables have weak connectors. Lightly crimp the center with small pliers as to compress top and bottom. I said lightly. It will put more pressure to the internal contacts so they are snug. May take a few attempts as you may be too light on crimping, but that is a good thing.

Clean your cable heads with fingernail polish remover
Let it dry some and push it in and out of the charging port til you get proper amps
