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.

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.
I have a weird problem with my Note 2. Recently my phone was repaired ( changed Display and Main board)
working fine at today Afternoon, but now my phone is not charging with my Stock charger, my brothers phone charge with my Charger but my Note 2 wont. I tried his charger and it works, then I connected my phone 2 pc with the same usb cable I used in my charger, and it charge but pc cant recognize my phone, Same cable work for other phone and charger also work for other phone.
I Factory resetted my phone but not working Switch off, Battery pulled out. still not working.
Do I hv to Reflash my phone.
I'm downloading DN3_v5+ rom
I'll try this one.
But it will take around 4hrs, and what if it wont work.

It sounds like your USB port on your phone is messed up. A lot of times with a bad micro usb port it will either not charge but sync data or it will not sync data but will charge. Also this goes for the actual usb cables as well. If you use a known good usb cable and it will either not charge or not sync dats on your pc, then it's most likely your usb port on your phone is bad. Even the refurbished devices sometimes will have bad ports that were not fully tested before passig QC so this is what I suspect is going on with your phone.

I've heard a bunch of people having this problem. My temporary solution was buying an additional batter w/charger for battery. But the usb flex cable I repaired myself last week. The part was $11.00 and the tools to pry apart and unscrew the phone were about $10.00. There are several tutorial videos on YouTube that guided me through the process.
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.
I've had my G4 since almost launch day and within weeks the supplied USB cable stopped charging the phone. I thought it was a cable problem, but it worked fine with other devices.
I tried other cables with the G4 and these still charged it so I thought nothing more of it until charging degraded with every USB cable I own to where the phone would only charge 20-30% during an overnight charge and the phone would frequently not recognise it was plugged in at all. I contacted LG who did a repair under warranty and all was fine.
I've now had the repaired phone back for about 3 weeks and the same problems are starting up again and it's only a matter of time until I am forced to return again for a repair.
Is anyone else having similar problems? I thought I may have just had an unlucky manufacturing problem, and the LG reps confirmed that to repair my phone they basically replace all the internal circuit boards and components rather than just replacing the individual component that is faulty (in this case the USB/charging port)
Basic debugging includes asking stupid questions, so please forgive but still answer any of those
Are you using a different charger? If so, check if that one is within specifications and if you do send in for repair again, use a different charger.
Are you propping up the device at an odd/weird angle or in a dock of some sort with the cable attached?
(As they replaced the entire print, it's probably not this, just the USB-micro port bent or broken.)
You could double check the wall outlets being used, there might be some kind of electrical problem there.
Either using all kinds of fancy electical testing gadgets, or stick a USB light into the hub or charger, does it flicker?
When sending it back for repairs, did they check the stock charger as well?
Hopefully these questions help you find any logical or plausible cause.

Hi FreezyExp,
1. I am using the standard charger that came with the phone, but this has not been repaired/replaced. I have tried other chargers too, but all the same issue.
2. No weird propping up or anything like that. If I hold my phone while it is plugged in it is constantly vibrating as the charger connects and disconnects, and if I place it on the desk to charge I have to ensure that I have at least 3-4" of cabe "on the desk" to give it enough support to make the connection.
3. Wall connection is fine and I have tried it with a range of outlets around the home, both with extension sockets used and plugged directly into the wall and there is no different. No flickering light when using a USB light either.
4. When I sent it back all they asked me to return was the main section of the handset - so no battery or rear cover, no cables or chargers etc
It does seem to be the same issue as last time, a USB connection becoming loose from the main motherboard, but it seems weird that I have had the same issue twice in the space of 4-5 months.
I've been having some sort of problem with my G4 usb port. If I plug it in to a computer, it will lose connection and get a connection again if I barely touch the end of the cord at the phone end. I've tried many different cords and different usb ports on my computer, but it still has problems.
I can't fast charge, either. When I plug it in to fast charge, it actually starts discharging even faster. I've had some extreme battery life problems, too. It drained from 100-36 the other night with everything disabled, and it's been doing that kind of thing a lot lately. I'm guessing that the charging port is what's messing up my battery life because it won't charge correctly.
Never dropped it or anything.
I got my G4 on January 24 and my USB port has also failed. I am getting a replacement from Verizon, but am concerned that a six month old phone has this issue.
I also own a G4 H815. A while ago the phone started not receiving any charge from the cable and I would have to prop it up from right under the cable's micro usb end. Thought it was because it was bent inside the port and not making connection with the cable so I had the port replaced. Now I'm experiencing the same problem and I think it might be the cable that's already gone kaput and is effing up the port itself. I took the phone to the same place to get the port replaced again and bought new cables (I lost both the original adapter and the cable, which were charging slow anyway. Now using a 2A Asus adapter which works great) and when I asked the guy at the repair shop, he says it's a chronic issue with G4 devices. I don't really understand how it would happen twice in just a few months even with a new charger port. What should I make of this? Did they replace my port with an already faulty one, cahrged me full price and now trying to sell this bogus or am I really doomed with this phone?
So charging is extremely slow now: max 280mA showing in Ampere app. Tried different cables and chargers(QC3.0 certified), charging speed remains the same.
I can't connect to PC anymore. Windows doesn't even make a sound when I connect the phone to PC. Showing no device.
Headphones connected to USB port are playing only one audio channel.
I've been using LOS 15.1 since last summer without problems, haven't done any updates since. The problem with USB port emerged a month ago and I am almost convinced it's a HW issue. AIDA64 indicates no temperatures over 36°C in thermal section so sensors are working fine I guess.
Anyone tried these charging ports from Aliexpress? Comments indicate that they are not the same as the original.
It really sounds as hardware problem. I asume you already tried with the phone off, and after factory reset and the problem persists.
In my experience, the original lower board have fuses which are expensive and are replaced by resistors on chinese replacements. If you dont want to lose this, try going into a repair shop and have the USB-C port replaced or desoldered/resoldered from the board. Must be done by experienced guy or it will be melted.
I'd buy the replacement board anyway. As long as you don't use crappy chargers, you shouldnt need the fuse too much, and also, the phone have another fuse in the motherboard.
If you have not tried with the phone off, try it. I got the xiaomi wireless charger and it works like crap with the phone on. it disconnects/maintains chage/stops charging A LOT, but if I charge the phone turned off it charges without issues at full power (8-10W according to my USB meter). Maybe is just the firmware being an ass
Thank you for insights. I confirm that hard reset nor charging solved the missing QC3.0 functionality. It's clearly a HW issue.
The whole situation was caused by losing my original charger on a trip and then using certified QC3.0 charger (not from Xiaomi) and unfortunately - cheap Chinese micro USB C cable. I can't stress this more... Never use cheap cables (or chargers) they can literally fry up your port. In this case it was definitely the cable eventhough it worked fine for 5 months.
It seems (from comments) that beside fuses the charging ports from Aliexpress are missing the possibility to transfer data over USB as well. Which is not that crucial because FTP over WiFi is bearable. The real problem that I need to fix is quick charging because with 280mA on Ampere app it takes 5 hours to charge this phone.
The charging port I've bought on Ali is on its way so I will update this thread in a few weeks after inserting it into the phone.
Losing data over usb is quite a problem if you are into custom roms/mods on native miui (which resets the recovery on each update).
Hope that ali's board does have this funcionality. About charging, you can get locally a wireless charger for now, though for me it only charges fast when the phone is idle, using it always just keeps the charge (probably to avoid overheating).
So how the story ends? We're you able to solve the problem?
I had the same issue with my Mix 2. bought a replacement port from Aliexpress and Witrigs.com. As posted on most forums these replacement ports don't support fast charging (in most cases) and no USB data transfer (this is the case with mine).
I had dropped a message on the witrigs.com website to confirm if their supposedly 'OEM' replacement supports data over USB (it looks much more like the original board in the phone that the 'custom' replica one that is half the price).
but I'm not very hopeful of that being the case, given someone has already left a comment on the product page indicating they bought the OEM version and faced the same issue with no quick charging or USB data transfer
Got some problem when i lost my usb travel charger on a trip.
and now my phone was too slow and cant transfer data even if i buy the new authentic from xiaomi store.
i hard reset for 3 times and but no luck.
omg -___-
I know it's old, but I'll let you in on my problem.
I have the Mi Mix 2 and it was happily fast charging until recently. Still the original plug and cable
I have tried all sorts of theories to get it fixed and one person said to charge it while turned off
So I plugged in my usb cable and turned off my phone. Only for it to automatically fire up and go into fastboot. No charging. Just fastboot on the screen
Obviously I can get out of fastboot mode again, but is mine an option change in the settings that needs addressing?
Thanks
