You probably have a dead battery...Someone who has seen this problem before could confirm.
The way you write is pretty hard to read, so you might wait a while until someone does confirm this .
1. Never charge the phone for the whole night.
2. I had the same problem. I changed my charger and now, it is perfectly charging. Try it.

thanx for suggestion, how much do i hav to pay for a new charger??
But you said you left it to charge via USB cable on your PC and it didn't charge properly. If you used the same USB cable with the charger, then the cable might be to blame. You should try a friends cable before buying a new charger.
If the charger does not work with the same USB cable you used to connect to the PC, your battery is most probably dead.

Charging all night isn't an issue.
The battery will charge to 100% then drop to 95% and back up, will cause no damage.
Also smaller and often charges are better for the battery as it slows the formation of crystals so the battery holds its capacity longer.

If you have used 2 different cables to charge and none worked properly, that is probably too big of a coincidence. Your phone has something broken; it's either the battery or the charging circuit in the phone. You should take it to a specialized phone service to see what's wrong. They will also try charging it before disassembling, and if there's nothing wrong with the phone, they probably won't even charge you anything.
If indeed they have to disassemble it, you should ask them if there will be any visible differences once they assemble is back. I had a cracked digitizer on my old One X and took it to service and replaced the display+digitizer(they come together) and, although the screen was new, it did not fit as snugly as before, so you could see light leaking out the side margins of the display.
They probably had many of these phones under repair and should know if this will be the case with your phone.

thnx bro, my phn is fully charged now but ill be visiting service center..
You can use/try every USB charger and cable you have in your house, I also charge my HOX with my iPad charger (only different cable ) no porblem at all. And it's no problem to charge your phone the whole night.
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.
I have been having this issue for a few days where the phone will detect the charger and it will display the charging sign. However charge wont go up and in fact sometimes it goes down. This problem however doesn't happen when fully off and works as usual. I've used ampere to check and noticed i only get about 150ma where as before i would get constant 1500ma. I tried different plugs, different cables, software repair, hard reset, safe mode. Nothing works

I was able to get just charging working (slow charging) when the phone is on by filling the battery to 100% when off and then leaving it unplugged for a few hours after that. I then turned it back on, used it for a bit until it reached about 70% and then charged it with the phone on and it began to charge again ( its pretty slow compared to fast charging but its a start).
Other possible solution.

I read somewhere that a corrupted SD can cause this issue too so I also removed my SD card when doing the process i mentioned above. Not sure if this is what solved it but you might wanna give it a try.

i dont think so. may be problem with the charging connector. there is possibility to poor contact between connector and PCB board due to solder connection or may be possibility of loose connection between connector and charger pin . so slightly press the charger pin and connect and now then its charging . just try
Works
I don't know which of the two methods it was but fast charging became usable again and works fine.
I plugged in my Zuk Z2(plus) into a charger yesterday happened to be a fast charger QC and within about 10 minutes it went up in smoke charger seems fine (cable melted) but the phone now only shows the ZUK logo and switches off,
Doesn't seem to charge either just vibrates, from the looks the charging ports a bit melted, Was lucky it didn't properly catch fire,
Anyhow to the question, I can get to (stock) recovery and I imagine I'll need a new charging port, but anyone know if the motherboard is likely fried too or would I get away with a new charging port on it ? (and obviously never charge with a QC again) .
I had the same thing happen to me. I was charging my ZUK in another room using a Quick Charge 3.0 charger. I went to check on it. There was smoke coming from the charging port (which was scorching hot) and a horrible electrical smell. Phone wouldn't turn on. From what I remember it was just a white LED when pressing the power button, maybe the vibration too. I tried to charge but it wouldn't do anything. Couldn't boot to EDL mode. I thought it was dead.
A few days later, I remember plugging the phone into my laptop (in another attempt to diagnose the problem) and at some point I got distracted and left it plugged in. After about 30 minutes I was suprised to see that it randomly powered on by itself and came back to life. I believe I still had trouble getting it to charge, and that the battery percentage was stuck on 0% when when plugged into the mains. But eventually it all just fixed itself and I have been using the phone for another 2 years without issue. Guess I got lucky.
Sadly it sounds like your phone is a little more damaged that what mine was. I did not have any visible damage, it was just a bad electrical smell that remained for a few weeks or months. I have heard from other people who had this problem and I believe there is a little component on the motherboard that overheats and burns out when trying to use a Quick Charge mains charger. But the phone works fine without it. I know the charging port is fastened to the motherboard so it would probably require soldering.
Example of replacement - Try looking on other sites like AliExpress: https://www.maxbhi.com/charging-connector-for-lenovo-z2-plus-32gb-zuk-z2.html
Don't I remember people hacking "the fast charging chip" off the board to fix this problem? Literally prying the chip off and it sorting this issue out and allegedly the phone working well. Try a search for something like that.
I know this was a common fault with fast chargers killing the phone.
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.
