My phone is not charging nor recognized by pc

Ok this thing is driving me nuts now. My phone didn't charge but it recognized my usb otg so i thought my batyery is dead. I tried another battery and my note was charging it just fine. So i decided to buy a new battery. I bought a probably fake one but again my phone wont charge the fake and my friend's note is charging the fake just fine. I connected the phone to pc were the led became red and the battery widget said that the phone was charging. However it wont recognise the device. Also rebooted to twrp and tried asb sideload but again it wont recognise the phone. My note is rooted using mr luong rom. Please help me! I havent seen such a thing before!

Change the plug, your cable is okay just the plug is damaged, the original battery also okay. Check after changing the plug, and remember- always use samsung original.

My phone is not fast charging

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.

USB C just charging on one end when turned on

Hi everyone,
Something really strange happened to me last week (or at least I started noticing it last week)
First, when my HTC10 was turned on, it didn't recognize the charger at all, I tried different chargers and cables and the result was the same. If I turned off the phone it worked perfectly. I wiped the cache and tried again with the same result. I booted in safe mode and got the same result.
I hard reset my phone and loaded all my apps again and now the USB C just works when I plug it in a certain way when turned on(one of the two possible ways, impossible for me to know which of them). When turned off it works perfectly.
Does anyone has experienced this? I think maybe it's related with one app, since when turned off it works with no problem.
UPDATE:
I just hard reset my phone again and loaded NO apps but still the same behavior: when turned off USB C can charge the phone no matter which way I plug it, but when turned on it doesn't.

Power phone up with it plugged in. Does it charge then? I get that problem often. I've narrowed my problem down to when I start my car with phone connected on charge (using car charger). Won't charge after that till I restart phone. I'm assuming it gets over or under voltage and safety circuit kicks in until restart. In your case it might be a charger or cable problem (or combination of both).

I think the problem was the cable I was using, after a while it started doing some crazy stuff like saying that I was not using a powerful enough charger. After I changed it everything is working like a charm

I'm experiencing similar problems, but this happened to me after my phone totally discharged, i repost my experience:
Hi guys! i'm occuring in a big problem, i was wondering if anyone of you had this experience with this or others phones, two days ago my htc 10 was totally without battery and died, so i put it on charge, but nothing happens, no led on, if i try to power on, no signs of life, unable to make it boot, even after hours of charge, i noticed that the phone anche the charger were cold, instead of hot like it should.... but after hours, even without led indicator on, i trying to recover it, with surprise, it was hot, i tryed to power on, no signs, i tryed combination of power button and volume buttons and it booted into dowload mode, and after a millisecond it re-died, and booted normally with 65% battery. BTW from that point the phone is unable to charge if i plug the cable into it, nothing happens, but if i put the cable, when is off, it charges even after boot, i tryed to recalibrate battery but nothing happens....
today, one day later, it seems the things are getting better, i'am able to charge it without having to put the phone off, but i always got the message that the charge is slow.

Clean the connector on the phone, make sure it's nice and shiny.
Give the cables a buff up, reboot your phone.
Allow it to boot, connect the official HTC charger in the wall.
Connect the official htc USB c cable into the charger and unlock your phone.
Connect the cable to your phone.
If that doesn't work, try a different wall socket.
Are you on stock? Have you altered any voltages? Any quick charge mods?

If you can reverse the modifications you've done to it I'd be tempted to say take it back to htc and get it sorted. Shouldn't be like that. Personally that's what I'd do.

Phone not recognizing AC charger

Hi
I've been having a problem with my G4 for the past few days,
when i connect it to the wall charger it recognizes it as if it was charging
via USB not AC as it did normally, and when i connect it to my laptop it charges,
but won't let me use LG Bridge nor LG UP , and im not able to browse the internal memory
I've tried using several chargers and cables in several combinations with the same results ,
it only charges as AC with a no brand 1000ma charger that i had lying around and whatever usb cable i put on it.
is it possible that the usb on my phone is broken? or could it be something else?
already did a 3 factory resets and tried to flash a diferent firmware
but that's how i realized it didn't work on my laptop either.

and are the drivers installed? was it working before .? weird thing is you said it doesnt worked in another PC. make sure drivers are installed and i guess the usb cable could also be the cause.. it has happened to me that it wont recognized to transfer files. only way i solved was reformatting my Pc install drivers and voila.. but first make sure as its not working in anothe PC.

just tried on a third computer and nothing
all computers have drivers installed, tried several cables, i don't even care about connecting it to a computer
i just want it to charge normally with an AC charger

i tought you said it charges, but you cant browse files . then it must be something wrong with it. i guess send it in for repair or contact your retailer. or carrier.

yes if i connect it to a charger or to my computer it charges,
but when i connect it to an AC charger it shows up as charging as if it was connected to a USB port
so this makes it charge very slowly , taking hours to charge with a 2.0 qualcomm quick charger instead of a few minutes
when i connect it to any computer it charges but i can't browse files or connect using any software
i tried using several chargers , the stock charger that came with the phone, one from a G3 , a QC 2.0 charger, several samsung chargers, and others and only one shows as AC charging.
so yeah it charges but not as it should

did you tried ampere app from PS. so you flash back to stock using stock firmware. and samething. what variant you have.? its very weird. but the best thing to do is if u are under waarranty send it for repair...
my story its different. i have original charger.. i use ampere app adn measure and its a 1.8a stock G4 charger, when i use another Lg charger i think its 1.2 i get more voltage with the 1.2 then 1.8 i switched usb cables samething.. very odd too.

i have had the same issue i have been able to solve it (luckily i am trying to update to mm via lg bridge it gives an error after which my cell doesn't show on pc neither it charges as an ac via wall charger so heres what i did)
you need to do exactly as described
1: connect your cable to wall charger(mounted to socket=on) and mobile
2: turn off mobile(do not unplug cable until mobile completely off ~10-15 sec)
3: unplug cable after off
4: press power button and than insert cable (within 4-5 sec)
5: let it start (it should b on AC charging)

only way is to take it to telcel and have it fix. or search i have no idea.

just as an update, i took the phone to my carrier, to make a warranty claim, see if they could fix it, they sent the phone to LG and returned to me, said as i have the camera lens glass broken the warranty was void and they wont perform any repairs on the phone as it was cheaper to get a new phone, also they didn't tell me what the issue with the slow charge was, im under the impression that they only saw the shattered camera glass and said F**k it
im not sure if taking it somewhere else and replacing the usb port will help somehow

N5110 charging problem

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
