Phone sometimes does not charge when plugging into charger? - Samsung Galaxy S8 Questions and Answers

Is there a known issue where sometimes the phone will not charge when you plug the phone in to the OEM bundled AC adapter/cable? I have found that the type C USB cable is not really reversible, it only recognizes it when plugged in one way, but if you turn it around it will not recognize it and won't charge. Am I the only one this is happening to, or is there a known issue out there with Galaxy S8's not charging all the time? FYI I have a Snapdragon variant in the USA.

I have not heard of any issues as you state. I tried my charger and both ways charge the phone. Try another C cable and see if you have the same issue.

Generic USB cable when charging phone hits 100% but never says it's charged

Got an old iPhone usb charger with a generic usb lead which charges the phone fine but when it hits 100% the alert to say it is fully charged never happens yet if I then change to the official samsung usb lead after 5 or so minutes the phone then vibrates and says it is now fully charged.
Not so much an issue as the phone charges fine just wondering if anyone else has seen this
The good news is with this 'feature' the phone doesn't wake me up when it's finished charging!
I've seen problems like this when using other generic usb chargers on other phones. I believe the wattage provided for charging can vary, which can cause issues.
I used Samsung's data cable connected to an HTC charger and the phone launched the MTP screen and tried to connect to my power outlet via USB. I haven't had a Samsung phone in years but from this I'm guessing that they're pretty sensitive when it comes to cables and chargers. I ordered OEM cables and chargers just to be safe.

Charger issue

I haven't seen anyone else complain about this, so it might just be a small defect or isolated incident.
I always charge my phone during the night while I sleep and just recently woke up to find the phone only at ~70%. For some reason the AC adapter seems to be malfunctioning. Since the issue has started, I managed to get it to charge to full one night, but the rest of the time it seems to stop charging. It recognizes it being plugged in initially but then it pops up with the notification saying that the charger has been unplugged. I've tried reconnecting both connectors which will sometimes get it to start charging for 15-30 seconds before it shows as disconnected again.
It works fine via USB connected to a computer so I can only assume it's an issue with the wall adapter. I'm not sure if there's much I can do if it is an issue with the adapter but wanted to see if anyone had any ideas that would be worth trying before I give up on the adapter. Also wondering if anyone else has had this happen.
I don't have that problem. Call and get it replaced. All you news is a USB AC adapter.
Have you checked the socket you are plugging the charger into? Have you tried a different wall socket or socket on the power strip?
Are you using a Motorola brand wall outlet and usb? I was using an aftermarket cable and had this issue. So I got a branded cable and now it's fine

i had same issues
my atrix would only charge also to 70% so i was about to return it. i forgot that it also came with a stand alone battery charger to charge just the battery. charged it and then put it on my atrix and said 100% again. hope this helps..
Yeah get the wall socket and make sure that's not the problem. Also I can't imagine it being the cable I use a 15 foot after market cheapo cable I got off newegg for like 3 bucks and it charges my phone all the way and I don't even use the wall adapter moto gave me I use some random one that's for one of my old phone or my nikon camera I don't remember. Also moto cable is crap it doesn't let me use adb doesn't seem to push enough power to my phone.
But thats just my 2 cents

Use the cables that come with the atrix.

Charging Problem

I am having trouble charging my tablet. When the tablet is on, I am unable to charge with either the POGO or USB cable. I have also tried other wall chargers for cell phones. I was not using any roms, but had tried out the ktmantra kernel. I have since wiped my tablet using a factory 4.2.2 image from google and am still having the charging problem.
The only way I am able to charge is by charging with the tablet off. It also takes ages to charge (12+hours). Any ideas on what could be causing this? When I plug the POGO cable in, it says it is charging, but the battery percentage continues to drop.

I've readed some comment on another forum from an user that has the same proble, but for him it takes about 10h. Not sure what's wrong.
Are you not able to charge at all or just very slowly? I just noticed that my Nexus is charging very slowly with the Pogo cable I purchased. I may try going back to the usb cable to verify that the problem is with the cable and not with the tablet.
I was getting very slow charge rates with my usb charger. Around 12 hour charge times even when completely powered off. Anyway, my problem was with using a USB extension cable. Since I started plugging it directly into the wall I've been seeing charge times in the 5-6 hour range. My iPad never had an issue with it, but whatever! You might also try a different wall outlet.

I cant seem to solve this problem. I have tried using pogo and usb cables with two different chargers. I have also tried using different wall mounted phone chargers. I am not able to get any positive charge while the tablet is on. Using the battery monitor widget, I used to see a +1800 charge with the pogo, and a bit less with the usb cable. Now, the highest I get is -500.
I am only able to charge when the tablet is off, although very slowly. I had it charging all night, and it is now at 60%
When I plug the pogo cable in, the tablet will say it is charging, but it really isnt doing anything.
Any ideas?

Recalibrate battery? It's probably not going to work though. RMA the tablet as a last resort.

How can I recalibrate the battery?
Im in Europe until June, so Im assuming it wont be easy to RMA.
There is also a strange thing going on with the usb cable. My computer is unable to detect it as a storage device. When I plug the charger in, it will not show up as charging when the tablet is on. But, I am able to access the tablet via fastboot.
Where is that oficial pogo charger from samsgoogle? 4 month and counting... 2 Biggest companies în the world are unable to produce a simple cable... Hillarious

The N10 charger is a 2 amp charger and most phone chargers are 1 amp chargers. The N10 will charge slowly with a 1 amp charger if it is powered off, however it needs 2 amps to run the N10 and charge at the same time. Also I have found that not all USB cables are created equal, you may want to try another usb cable. I do not know anything about the pogo chargers. Hope this helps.

Charging problems

I just got my Note 3 working thanks to this group. When I first got it, it was without a battery and was locked by PIN. I was able to wipe it to factory conditions, but now it will not charge. It charged right away when I first got a replacement (OEM) battery, but then, I did the system factory reset, and now it will not charge. I am using a USB 3.0 cable and connecting this to my Apple charger I got with my iPhone 6 as I don't have a specific charger that might have come with the Note 3...just a generic USB 3.0 cable and the iPhone 6 charger that the USB cable plugs into. Any thoughts for me to try?
Try plugging the cable into a computer. It might not charge fast but it will let u know if it will charge or not. Iphone charger might not be compatible so battery will not charge.

I have tried using the computer and that is part of my confusion...the phone will indicate it is charging...but it doesn't. I get the same indication whether I am using the computer with USB 3.0 cable, or using various wall charger pods with the same cable. It will show the charging symbol (lightning bolt) or, if turned off, but plugged in, it will show the upflowing green drops rising toward the battery. So, it seems to indicate it is charging, but the charge percentage never increases...only drops.

It's not unheard of for a brand new battery to be defective. If you know someone else with a Note 3...try swapping batteries with then and see if the problem moves with the battery.
There is nothing in a factory refresh that would effect the charging circuit.

Fast Wireless Charging Works but regular Fast Charging does not.

Like mentioned in the title, my fast wireless charging works, and when I put my phone on the pad it tells me it is fast wireless charging. However, whenever I try to use the cable directly and not wireless charging, it becomes cable charging which is incredibly slow (8-10 hours for 50%).
I have obviously checked all the simple steps. I'm using the adaptive charger, I'm using a good cable, fast charging is turned on in settings. I even tried factory reseting my phone but still no luck.
Is it possible that my charging port is loose? And if so is there any way to fix this?
The other possibility I'm thinking of is that my Europe to America convertor might be bad (I have the international version so I have to use the plug convertor) I recently lost the one that came in the box so I had to buy a new one off amazon. Are there such good things as good and bad convertors or are they all the same. And if it is the convertor, why would the wireless charging work but the cable charging not.
EDIT: I just checked plugging in an S6 to the cable and it says fast charging. Does that mean it is definitely the port on my phone?

May sound odd but have you tried unplugging and replugging the charger in over and over to see if one of those times it pops up as fast charging?
i had this problem with my Note 5 (im in the UK and note 5 was not released here so i had to buy a Russian variant and they sent with 2pin to 3pin adapter)
I don't think i ever had a fix for this other than using a different fast charger without the adapter..
However like you The official note 5 charger with adapter does work to charge my s7e fine though
so our problems seem pretty similar... Maybe buy a new fast charger that doesn't require an adapter and try that?
