Fast Charging No Longer Working

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.

Charging problems

Experiencing some frustration with the fast charging option. I attach the charger, and no notification pops up saying "Fast Charger Connected"... but in Power Savings settings it says Charging USBicon1.png with the fast charging box checked but showing grey.
Used the same charger and cord in the same outlet earlier in the day and the fast charger works without problem. Been tracking this issue for two days and cannot figure out the variables creating the problem.
Tried different fast charger, different cables, different ports, cleaned out the port with alcohol and qtips....
Anyone else suffering the same problem?
Any insights that might lead to a solution?

Are you sure that the phone is seeing that it's being charged by AC and not USB? It may sound like a stupid question but my Note 4 recently suddenly started charging as if I'm connected to USB rather than AC, even though I'm using the same fast charger that came with my phone, and it does this about 40-50% of the time. I think it has to do with the cable I'm using, the one that came with the phone so it's 14 months old, but I'm not positive. It could be the port on the phone, which is the reason I'm mentioning it since you said you tried different cables, fast chargers, etc. I haven't noticed whether it happens when charging in the car since I don't do that much. This happened with one of my older phones also after I'd had it for a year or more, not sure if it was the S3 or Evo 3D, and back then I think it happened with any cable or charger I tried.
When this happens, I need to unplug the cable and plug it back in, sometimes it takes 4 or 5 times to get it to show as AC with fast charging.

I'm experiencing the same symptoms on two different Sprint Galaxy Note 4. At this point i'm pretty sure that is a software issue since now it's two different phones. I have tried 4 different chargers (one that was not mine) and factory reset one of them. Not sure what self updating or background self updating app (if any) could cause this problem. This is frustrating, it's like sprint and samsung purposely push software to make the phone suck and for me to update..

+1 on two note 4 's [emoji36]
One on KK THE other on LP

edit....delete.

I'm having the same issue. Fast charger is plugged in, but it is charging as if its plugged into a USB. It is taking ridiculously longer to charge the phone ever since the new update for sprint came out.

I was experiencing this on both of my phones before the update on the 7th of Dec got pushed out..

I'm rooted, running a custom ROM called Hybrid X 3.0 which is still OG5. This problem suddenly started out of nowhere and I hadn't changed my ROM so that's why I figured it must be hardware. Now I don't know. Makes me wonder if they could've put a kind of self-destruct code in the software to force us to get new phones. The ROM I'm running is based off of stock Samsung software after all.
I wonder if it would happen on a Cyanogen based ROM. I don't use them because I rely on my S pen too much to use AOSP.
Edit: Is anyone else seeing that their phone shows its charging as USB? Just curious.

Still experiencing the same thing. At this point I don't know what or who I should blame.

I myself was having tons of freeze issues and random reboots after the update on my completely stock phone. Not seeing the charging problem but since installing clean master and cm anti virus, issues were found and have since stopped. I definitely think there is something wrong with the latest update and could just be affecting people in different ways. I would maybe try clean master or something similar and see if your phone could just be infected with something. Might just have something to do with the latest "security" update. It can't hurt to try it anyway.

Stilll experiencing the same thing. I have factory reset several times, bought a new charger and still nothing. Must be a software issue. that took place in the background....

Is anyone else experiencing this?

Charging issue

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.

wireless charging strange behaviour

Hello,
since installing sep 1 security patch I have strange problem with wireless charging. It like recognizes the charging pad, starts charging and says "fast wireless charging" and says i.e. 45 minutes to full. Then a couple of seconds and it changes to "charging" and time changes to 3 hours. and then back to fast charging. And cycles this. And it doesn't charge much
Now I don't know if it's connected with sep 1 security patch but it started happening after that. I didn't drop it or anything. It charges through cable normally. The issue is not with charger, since I have 2 identical charging pads at home and at work, and the phone does the same with both...
Any ideas?
Thanx!

It is. I reported this to Samsung and it's all over Reddit as well that others on the latest update are having the exact same issue.
My other device still fast change on the same chargers and the only difference is that my S20+ was just updated. I don't plug my phone in, so I noticed it immediately as I just have wireless charging in the house for the most part. Thankfully USB C fast and super fast charging still work fine, but that's beside the point. I'm hoping this new update (when it's available) fixes this.

Wow, thanks mate, I was getting depressed because of this, good to hear it is a software thing. I'd hate to have to return it and get another phone took me ages to set it up and migrate everything from my old S8 plus

Question Not charging while using AA

A little backstory first...Just like soooo many others my P6P is kind of crap since the "stable" A13 release. Beta and 12 were great and I had ZERO issues. Since upgrading to the amazing stable version, I’ve noticed my phone does not charge consistently while plugged in for android auto. It will charge for a few minutes, stop, and maybe start charging. I've found this issue on two different vehicles and sever cables (A to C, C to C, and the cable that came with the phone). Has anyone else had this problem? Any fixes? Or will this probably be fixed in an upcoming update?

I haven't noticed this issue. I do use Android Auto everytime I drive, but admittedly, my wife and I work remote at home and only tend to go out for food or other shopping.

Damn, oh well. Thanks for the reply. I haven't gotten a lot of the bugs that others have had. I guess this is my special big

A lot of android auto USB ports only provide a very low power output, probably not enough to charge the phone
I have noticed this but with just google maps, plugged in for hours and the battery has been discharging, issue occurs with multiple adapters for me, 65W one, wireless device certified for pixel 4XL, another 30W adapter. What I believe is happeneing in these scenarios is that the phone is getting very hot therefore the charging is throttled to the point that it doesn't charge enough, why I say this is when I remove the phone it feels hot to the touch.

I thinking it has something to do with the power delivery too. The weird thing is, this did not happen on A12 or 13 beta.

no issue charging in my VW. charges rapidly too via usb c.
I do have an issue where occasionally the phone takes 2 or 3 attempts to plug in for it to start android auto but thats been on various android versions though and i think its more the software in the car.

Check your battery adaptive preferences in settings. Turn them off and see if that helps
