Hello,
My S20 (SM-G980F) today refused to charge wirelessly. I own it for over a year now and induction charging always worked - until today. I tried several times with two different chargers. Both discover the presence of a phone (by blinking 3 times) but charging does not start. Phone reboot didn't help. Charging by cable works. Nothing special happened to the phone, I didn't drop it nor anything like this. I try to charge bare phone, without any case. I'm on BeyondROM 4.8 (Android 12), flashed almost a week ago, don't think it's related to wireless charging failure.
Tried Logcat reader - no entries related to battery appear when I place the phone on a wireless charger but a lot of them when start charging by cable.
From various recommendations as to how to proceed in such circumstances I didn't try factory reset but I consider this a last resort. Did anyone encounter such a problem? Any idea what could go wrong or how to solve it?
Try disabling adaptive charging, make sure the wireless charging cable is not damaged, or you can also boot your S20 to safe mode and then charge your device.

Not sure if anybody has seen this problem when I plug in my phone to charge it doesn't always (once every 2 or 3 days) recognize that I'm charging it. When I shut the phone down it does recognize the charge and can then reboot and it'll continue charging. However if I reboot without plugging the phone into the wall briefly, then it'll continue not realizing that I'm trying to charge it.
This has been going on for about two weeks now (I've had the phone for about a month and a half). The phone is rooted, but otherwise it is stock. I do two small but noticeable scratches in the plastic, so I don't know if verizon will let me get an exchange.
Anyway my question is has anybody seen this before? I found a couple threads on the reverse condition (phone thinks its charging when its not), but nothing on this condition.
What cord are you using to charge it and what is the amps on the little power unit? I was having some trouble on the plug that negri gave me and I use my old HTC 1 amp plug with my new Sammy cord.
A. Try a difft power unit
B. Try a difft cord

It's probably the charger. One of my car chargers will do that. Also, this doesn't sound like the case, but be aware that your phone won't charge if it's extremely hot.
Probably the faulty usb port issue. It is no way to fix it without changing the port.
Happened to me once. What fixed it was taking out the battery for 5 min, then replace it, and power up. Someone else was having the problem and another person suggested the long battery pull. Worked for both of us.
I'll try the long pull and report back.
I use three different chargers. The factory samsung charger, a Seido Docking Station (powered by a generic USB charger), and a generic USB cable for charging from my computer. Condition has been present on all three.
Is it recognized by your computer? If not, the USB port is probably the issue. If it is, then the battery pull may fix it. If that doesn't, make a Nandroid and do a full system wipe and see if that helps. Have you installed any apps around the time you noticed the issue? If so, uninstall that app, reboot and see if that solves the issue.
Example, I had TweetDeck kill my GPS once. Literally, I used navigation, got where I was going, remembered I hadn't installed TweetDeck, installed it, tried using navigation and it was busted, uninstalled TweetDeck and Navigation worked fine. I rebooted, reinstalled TweetDeck and all was good. Quirky things happen sometime.
any news on this? my usb port has recently stopped working but it still charges

I wanted to share this in case anyone ever experiences the same problem. I had my Note 4 since it was released in October and didn't have any issues until roughly a week ago. All of a sudden, the phone would not fast charge. Whenever connected to the fast charging adapter, it would detect it and charge, but it would not give the fast charge notification and would charge extremely slowly (8 hours to get a full charge from near empty). In addition, my PCs would no longer be able to access it and the phone would not give the MTP option menu when connected. I tried multiple cables, outlets, fast chargers, and batteries in addition to toggling the fast charge setting, wiping the cache, and performing a factory reset - but nothing helped. I finally called verizon and they sent me a new note 4 and everything was working again.....
Three days passed and the same exact issue occurred again on the replacement phone. This makes me believe that the Samsung charger I have has somehow deteriorated and is now breaking the usb connectivity on the phone. I contacted samsung and am getting a replacement for the charger and will have to get ANOTHER replacement phone from verizon (after they finish processing my first replacement).
So if anyone has a similar issue, I would suggest getting a new charger in addition to the phone replacement so you don't have to go through the entire process again. I could be wrong that the charger caused this, but I can't think of anything else besides the recent lollipop upgrade - but everything was working for several days on lollipop for both phones.
If anyone has ideas on how to fix this, please let me know. I can't return the second phone until the first one is processed so no fast charging or PC connection until then. Thanks
Having exactly the same issues. Let me know if you work it out.

Same Issues and I have three fast chargers so it is not the charger it is the phone or the 5.0 update.
Mine was not really even charging unless I turned the phone off. I called Verizon and they are sending me a replacement phone overnight. It would not connect to the computer either. I hope this is not a result of fast charging, if so they are gonna get a lot of phone calls
I also have another fast charger which wasn't working... I was thinking that my main charger was breaking the phones USB connectivity and fast charging, but if others are having the same problem then I am wondering if it is something related to the lollipop update. I am replacing the main charger and should have another replacement note 4 come Friday. If it happens again, then I think it points to the lollipop update since both phones had this issues days after lollipop was installed.
I'll let you guys know the outcome
Had the same issue. Used a different wire. Solved the problem. Any Micro USB that can transfer data, can use fast charge. If it's a "power only" cable, or if the data pins/wires are messed up, no fast charge.

Well the problem was that all the cables were working and then stopped. When I got the replacement phone they worked and then a few days later the same thing happened again. So something was causing the connection to break completely. I am hoping that the cause was the charger which I am replacing.
Word of advice: if it stops charging normally In ANY way. THROW AWAY THE CHARGER. I made the same mistake and my Note 4 literally lit on fire melting the lower 1/2 inch of my phone and completely melting the charger. It was so hot by the time I was able to yank the cord out both the phone and charger were melted and destroyed and I ended up with three fingers with minor burns. I am lucky it did not happen when I was sleeping with my infant nearby. I now charge my phone only in the day and on a granite counter in case of fire again.
It stopped fast charging. Then I used the charger again and got a message saying "Transferring power to high powered device" then wham 2" flames
Verizon kept claiming it couldnt happen and thought I used a aftermarket charger until I brought the phone and charger to a corporate store and they prompytly replaced both the phone and charger under factory warranty.
I have three samsung original fast chargers and none of them worked plus the fact that the phone could not be connected to any computer I have makes me think it was the phone. I got the new phone today so I guess time will tell. I just can't see three chargers and cables going bad all at the same time. I also did not take the 5.0 update on the new phone.
my replacement phone stopped fast charging and computer will not recognize it now. I used a different cable that was plugged into the fast charge module from Samsung. I guess that is what caused it. They are sending another phone but for C sake if a cable is the reason this happens surely there should be a fix without replacing the phone time after time.
I finally received the new phone from Verizon and I replaced all the cables I was using to make sure this doesn't happen again. Hopefully the charger was the culprit and the problem is over and done with. Hope no one else encounters this as it really was a pain to deal with.
I got my third phone Monday and so far so good. I had a car charger from Verizon plugged into an extender that had 4 plugs in it. When I unplugged my GPS from it I noticed it was very hot. The Verizon Charger was also hot even though nothing was plugged into it. This may have been what caused my issue. It could have overheated. I replaced it with a different brand and tested to make sure it stayed cool when anything was plugged in and have used it all week without issues. The only other thing could have been the USB cable I used the evening before the second phone stopped fast charging so I do not use it either. So if you use a car charger extender check to see if it gets hot when anything is plugged in. BUT, it is scary knowing something like this can kill the USB on this phone.
I have an external Hard-drive that would constantly disconnect and reconnect with the slightest movement of the cord connected to the computer. It even caused my H/D to get corrupted twice requiring re-formatting. But all I had to do to fix it was to squeeze the big connector on the cord a little and tighten it up. Just a thought.
It's been a week since I received my third phone and everything is working perfectly. I can only assume the charger was breaking it and I'm glad the issue is behind me.
So for anyone experiencing this, I suggest contacting Samsung to replace the charger before going to your cell provider to replace the phone
I'm having the same exact problem. My 2nd replacement phone is now doing the same thing as the first one. I have too many scenarios now though and I'm confused as to which it is. I have two Adaptive chargers.. Batteries, phone, or chargers...
As soon as I replaced the charger, I didn't have this issue again. I suggest sending your chargers back to Samsung (or whatever other brand you have) because one of them is breaking the phones

I would place my bet on a bad cable. With the higher voltages that fast charge uses going through the danger of arching and sparking is increased especially if there's a poor connection would fry or weld melt metal inside the connector. This could damage the USB port in the phone and cause the phone's USB port to have a bad connection. This bad USB port in the phone could fry the other cables as well leaving you wondering why everything went bad all at once
My phone will fast charge on my two vehicle chargers (at 1.5 amps and 2.1 amps), but refuses to change any faster than 500 mA on two separate fast charger bricks. The same bricks work fine for fast charging other phones, so it's my phone, not the charging hardware. I'm using the same cable(s) for all instances, which leads me to believe that something is wrong with how the phone interprets the "smart charging" signal on the bricks, or that the phone is sending the wrong charging signal.
I can still connect to a computer just fine, so my issue may be different.
Does anyone else have the issue with bricks but not with chargers without "smart charging" capabilities?
I've had this problem on stock 5.1.1, Jasmine rom 6.0.1, and now CM13. I full wiped everything when reinstalling, so either it's hardware, or an issue propigated through many roms. I've tried a few different kernels too, just to see if that was the problem.
I'm changing the battery tomorrow to check that possibility. Maybe I'll bend the contact a slight bit and see what happens (phone catches on fire)...
Hi guys
I have the same problem as you ,so what I have to do to solve this issue without replace the phone,
I have rooted 5.1.1 stock rom, If i flash full stock rom 5.1.1 does this help or what?

Turns out one out of the three new cables I bought didn't work, and my OEM cable didn't work for fast charging. Swapping for a good cable fixed the issue.
hi.
my xperia arc (lt15a) has all of a sudden stopped responding to the charger - it won't charge at all!
tried other cables, tried connecting the usb to a desktop pc - but no respond!
the battery was at ~40%, and during the night I connected my powerbank to the charger, and the Arc to the powerbank (so trying to charge both of them simultaneously - something I never did).
in the morning I discovered that the phone didn't get charged.
I didn't worry much - I thought it was a bad cable, so I let the battery drain completely to 0%. but later I have discovered that it wouldn't recharge at all, and won't respond to a charger or a pc.
I have tried several things - which probably got the battery to get very drained-out. So now, if I try to power-on the device, it wouldn't turn on at all (it could turn on before), and the led near the micro usb port blinks in red for 3 times.
there is a very very tiny chance that a micro drop of rain got into the micro usb port, before the problem had started. But now I can't see any corrosion - maybe I don't know how to recognize it well enough? Anyway, I have tried to clean the port with alcohol and with electronic cleaning solvent (tuner cleaner) - but the phone still doesn't charge. maybe I didn't clean well? I really tried my best!
this Arc has mikeioannina's CM11 from 17.4.2016 - I used it for several months until now.
http://forum.xda-developers.com/showthread.php?t=2545354
the last thing I could do before the battery totally drained out was to enter the recovery mode (by turning the device on while holding the volume-up button), and then performing a factory reset. but it didn't help.
and I also want to mention that initially when the problem had started, when I connected the charger, sometimes the legacy xperia logo had appeared - but without the battery indicator afterwards (the phone just went off afterwards). now even this don't happen, and the phone doesn't respond at all to the charger. that's why I think it's a software problem, concerning the 3rd party rom that I've installed.
the mistake I've made was that I didn't try to reinstall the rom while there was still enough energy in the battery.... but I was abroad, and busy, and without a PC - so I couldn't perform it even if I was aware of the problem and wanted to solve it.
I don't have another battery or an external (desktop) battery-charger. and I am not enthusiast at buying these for this old phone (unless people here would be certain that it would definitely solve the problem).
I really want to keep using this device for a few more months - until the galaxy s8 / lg g6 would be released. I don't want to buy the current devices.
So could anybody help me?
hey i can help

Hi ,
i'm facing charging issues on my s 20 plus it is only charging on the cable mode and the super fast charging mode is on and i'm using the original charger and cable. I've tried soft resetting and turining the phone on on the safe mode and still the problem is there. I started having problem after getting a moisture detected notification on my phone and it went away but the problem is still after a day. Does anyone have any fix for this problem?
Just started having exact same problem, no ideas yet?
I thought my charger was faulty, same issue with me, no chance for my s20 to get charged wirelessly, no matter fast or not. I think the last security update was buggy maybe
It's not you. I noticed that my wireless fast charging immediately broke after the last update. They all start to fast charge, then a few seconds later reverts to standard charging.
Thankfully, I can still fast and super fast charge with my USB C chargers.
I saw it on different Samsung forums, Reddit and the Samsung Members app. All reporting similar issues and the only thing they all had in common was the last update. I do believe it's software and Samsung needs to fix it. I know my chargers work fine as my work S7 still fast charges on all of them but it's on an old software version.
Hi everyone!
I'm investigating charging issue with A70 Europe version.
Bought used one with stock ROM, then unlocked and installed crDroid based on android 10.
Additional modules: Magisk, EdXposed, FakeGapps, MicroG
Apparently after ~1-2 years it started charging really slowly.
(Used orignal adapter and cable) So I thought it was broken and changed it.
It didn't help
I recently moved to LineageOS 20 straight from crDroid.
Issue persisted and I was annoyed with it so much that I checked charging parameters with Wattz app from f-droid.
With different cables and adapters I'm able to achieve Max 0.4 A with 2A charger.
Where in most cases it is 0.1A with 1.5A charger
I got it to the cell phone repair where I said I suspect that it may be the port as it stopped transferring any data.
They fixed port but charging issue persisted.
In that moment I decided to try fix it myself.
I opened the phone and changed battery as it was also discharging fast.
It didn't help.
I started reading some similar threads here.
So what is left:
- change the tape that connects main board with port (it is said to be a common issue on samsung device)
- reflash stock rom and see what happens there.
what do you think?
do you need any pictures of the phone or other details?
Thanks in advance!
UPDATE:
Device is A705FN
Did both.
Changed ribbon cable that connects main board with port and flashed stock ROM based on android 11.
Disabled adaptive charging in settings.
But it didn't help.
This could mean that it is some other hardware issue but I'm run out of ideas...
Other observation:
Measuring Watts:
(Stock charger) When I power on the phone, drain is ~10W till it enters offline charging mode or system is on, then it stays exactly 0.5W ! I'm not sure if it is charging. When system is powered it says no.
To compare with my msm8998 based Sony Xperia ~10W till it enters offline charging mode, then it stays at something like 4.6W with 1.5A charger.
Both tested while charging above 90%
I'm totally pissed of. I put money to repair it but nothing seems to work.
I'm sure about one thing - I'll never ever buy any other samsung smartphone.
This sounds like a charging board issue from the very beginning. Charging problems do happen on this phone sometimes but usually just reseating the ribbon cable is enough to make it work again. Perhaps some chip has failed, though this happens much more rarely.
