Here's my PSA:
I plugged my old Galaxy S4 into my USB cable, not thinking or remembering that it was the Note 4 fast charger.
You would think that the circuitry would be smart enough for the higher voltage to not hurt the S4?
I left the S4 on the Note 4 charger for a couple days. While on the charger, the phone was off, but charging screen showed as expected. No problems.
When I went to unplug it, it wouldn't start... even with a new battery or w/o a battery with straight AC.
When you plug the phone into a computer, you hear the USB noise, but nothing else. The screen doesn't appear to work at all... all back. Can't boot normally or into recovery or download.
Took it into a local cell phone repair place and they said that I fried my eMMC. They if fixable it's either a new eMMC or it needs to be reflashed. not Odinable.
So, anyway, if you have a Note4 and older phones, I wouldn't plug any of the older phones into the new Note 4 charger. I can't believe I"m the first to run into this, but I haven't seen any other threads on it.
Thanks

This is interesting, but not surprising. Thanks for sharing.
As a rule of thumb, I've always used only the oem charger that the phone came with and nothing else. Even if I was sitting right next to a charger for a different phone, I'd always get my @$$ up and walk upstairs to grab my charger for that specific phone no matter how comfy I was. It has always been a habit fueled by my ocd.
Along with that, it all started when I had my note 2, which was also the very first time I've messed around with aftermarket batteries. What the heck I had though...few extra mAh...wouldn't hurt right? WRONG.
These were known names too like anker, etc...not some cheap knock off on ebay or anything. Until then and even now, I don't mess around with anything aftermarket battery wise or chargers...so what happened with my note 2 was that I started noticing the screen being washed out and everything just looked funny. Sometimes it'd flicker. Something wasn't right. Then my microSD started failing, mounting and unmounting etc... I immediately knew what was causing all of this...the darn aftetmarket battery!
So after putting back in the stock battery everything went back to normal.
Therefore, I firmly believe, let alone have been tramatized to never again mess around with all that crap. Only stick with oem when it comes to battery and/or chargers specific to your phone. That's it. I know now that there was something funny about the lack of inconsistsnt/spikes/spurts/uneven/whatever you want to call it, power going on.
So this all makes sense about the N4 charger, frying up some eggs. Doesn't surprise me one bit.
Stay with OEM. (Batteries and/or Chargers.) [emoji106]
There's no way it could hurt it.

charging through the night
was it not because u left it the whole night, coz i always interchange my note and s4 charges with no problems, but after hearing ur experience i am definetly not trying it again
Impossible
Why you left it plugged up for a couple of days is what I'm curious about.
Power surge, nuff said.
I think it's far more likely that your S3 was either about to die anyway and this was simply a coincidence, or that you had some other mundane issue - such as a power surge - while your S3 was plugged in. I can't possibly imagine Samsung would release a charger into the wild that would fry other devices.
Charged my old note 3, and s3 with note 4 charger.....no problems on my end.....
That's what I'm saying he said he left it changing for a couple days who does that?
Sent from another Galaxy! Note the difference!
ive occasionally used my Note 4's fast charge charger on my wife's Galaxy S4 and it hasn't been an issue. charges normally and haven't seen any side effects from it. something else happened to the OP's S4 that it fails to boot up properly.
I have use all type of charge on my phone, even those $2 charger that only gives out 1 amp. It takes long to charge.
I think its the fact that you left it in for 4 days was it?
Thats a long time to leave your phone plugged in...
Charged ton of stuff (iPad, iPad mini, iPhone, Note 2, Note 3, Note 4, Nexus 5, S4) with my charger. Never a problem. I am 100% certain it was not the charger that killed your phone.
This story seems very iffy. It could have been several things that caused the problem.
I use my Nokia 521 charger for all phones and tablets and it works perfectly, just a little slower.
I didn't even take the Note 4 charger out of the box yet.
Sorry for the delay in the replies.
I bought my Note 4 so I had my S4 set aside getting ready to sell it back. I sat it aside just in case I needed to copy anything else off of it. So yes, it was plugged in for a couple days although in the "off" state. The phone was in perfect condition ready resell. Trust me, I was bummed about it! I ended up only being able to sell the phone for parts!
The only thing I could think of is is either:
1) The HW circuitry in the charger tried bumping the voltage up to 9V one too many times for the circuitry in the S4
and/or
2) The slimmed down "phone off & recharging kernel" didn't have enough failsafe logic to handle this condition. The slimmed down kernel I'm describing is discussed by Chainfire's NoMoarPowah
and/or
3) Power surge
As far as random chargers go, they're typically underpowered. You typically will get anywhere from 700mA to 2100mA. That's just going to affect charge times but won't hurt you. None of them (as far as I know) try to bump the voltage up from the standard spec of ~5V.

I've seen that happen as well. Overnight charge of an S4 using a note 4 charger (with the phone powered down), and in the morning the S4 is dead (but very warm to the touch). Tried everything (including changing batteries, using original charger, trying to boot into recover/download etc) but it simply won't power up anymore.
Common sense says that the Note 4 charger should not be the cause, as it it still gives a 5V output as well as 9V, and so I had put it down to coincidence, but seeing that you've experienced the same thing, I'm not so sure. One thing could be is that I was on the old bootloader but newer rom. The old bootloader always had challenges with charging whilst powered off, when on 4.4 roms in the early days, before kernels were updated. Maybe something triggered the 9V mode on the Note 4 charger without the new bootloader/original kernels.
The charger says "adaptive" right on it. It lists on the back that it does 9V1.8A on the Note 4 and 5V/2A on anything else. It won't hurt your GS4.

Anybody ever hear of this?
Started intermittently charge/stop charging.. Then just stopped.
Rebooted? Nothing.
I have an extra battery...tried that....same thing!
Finally I wiped everything and it charged again...all night (thank God... I was at 15%)
BUT....checked just a bit ago and it was intemittently charging and stopping again...now I'm back to no charging. WTF....lol.
Only other info I can offer is the that at times I've used a second nonNote android charger (meant for my hotspot device...that does output to 1.2 but I don't think that would do anything..I used it on my Galaxy 2 Touch for months.
If anyone can give any insights I'd greatly appreciate.
I cannot charge my Note at all rights now.
Have you tried a different charger and/or USB cable?
Regards,
Dave
Thanks...yeah 2 different chargers. USB...you mean charging via PC right? You know i haven't tried it believe it or not!
I'm sure i could wipe everything again and it'd work again..but...big pain!
Right now I have to wall charge the battery itself.
Hey OP, any updates on this??
After I flashed Abyss 2.5 on top of Cassie's V3 on my Note a few days ago it started doing the charge/stop status and I could ONLY charge it while off and even sometimes it was awakening it self up!! And finally it gave up to no charge at all.
As from yesterday is officially "dead" since no recovery/download mode can be entered because of low battery. "Download" mode say's too low battery and it can't download.
Hey guys I really need some help on this. NO external battery chargers are available to try and no one I know has another Note to ask to charge my battery..
What do you thing? Faulty hardware/micro-usb port or something? I'm NOT blaming anyone since it's not a widespread issue but this DID happened ONLY after flashing Abyss 2.5 from CF KKA.
Thank you for your help guys in advance. Please let's try and resurrect my NOTE!
P.S: Also I forgot to add that immediately after flashing Abyss 2.5 I lost USB functionality in any way while power on.
I also tried:
3-4 different wall sockets.
2 different working cables. Original and one SE brand. Both working on other devices.
Tried removing battery MANY times.. left from 20sec to 1-5minutes etc(despair yeah).
PLEASE any info/help would be GREATLY appreciated..

And risk of having my 2year warranty thrown because of root or custom rom which they can blame for my problem? I think otherwise.
When I manage to charge the battery I might put everything back to stock and take it for a check if the problems continue.
Btw, you response: "...Instead of asking people here..." got me thinking a bit.. It should made you think a bit too.. Why?
Because 95% of your problems can be solve from online research. Relatively speaking of course. The ONLY times I couldn't fix something by my self(speaking for electronics, but can be applied on many other different occasions) was because of soldering needs which then I have a certified friend with good soldering skills and he does the job for me..
Example: One Acer 7736Z I was repairing had a blown/dead power ic chip. I ordered it, my friend soldered it since I never messed with soldering and all good. Done.
Another example: I have a Sammy 59D550. I had some problems.. Should I every time that I have a problem find a car to transfer it to the repair center/shop or do some research online which in the end I fixed my problem with a simple firmware update..? I prefer the latter.
Please excuse the comment, I meant it in a more generalized way, not directly to you, but that "...Instead of asking people here..." got me a bit going. No offense meant.

A little update on my "situation".. Phone is charging and ALL thanks to ephestione. Also I followed the video below and did exactly on my note and it's charging as we speak..
http://www.youtube.com/watch?v=9pYcgmLhUcQ
Procedure: As it might help future visitors.
I cut a mini usb since as I have many spare.
Attached only the red(positive)/black(negative) wires to the phone's corresponding battery pin.
Forced the battery in to secure a good grip between them.
Connected the other normal USB end plug to my Note's original Samsung USD charger.
Phone is successfully charging for now.
I believe what I did was wipe all and reflash, ...and all was well.
I have found my Note and SGS2 to be pretty sensitive to chargers. What do you mean outputs to 1.2? You need it to output at least 800mah, probably 1000mah. I would expect the Note to draw more power than the SGS2 but I'm not sure. I bought a Rocket Fish (good quality usually) charger from Best Buy. It didn't even say on the box but output only 600mah and the phone acted just like you are saying.
One charger I bought from Walmart, if I plug it in the TOUCH SCREEN STOPS WORKING!! Crazy!
I have had good luck with blackberry chargers. Make sure the USB cable you use is good also. I have had some that worked great with other phones and not with Galaxy phones, even some that worked great with my SGS2 don't work so good with my Note.
wipe battery stats
i reckon you hard reset and stick to OEM batteries, and buy an external charger on ebay!
I am also having a charging problem but it is because any charger that I plug in is loose in the phone and only having it in the right position works. I have tried many different chargers but my port on the phone is just too loose. How do I get it to a Samsung repair shop? I called samsung and they told me they only fix phones that are ment for the US and my phone is an international version.

Unfortunately, Samsung does not service international note in the states. They do not train as their product is not officially sold.

So am I just out of luck getting my charging port fixed?
My note did the same thing. I took some compressed air and sprayed the micro usb charge port with it a few times. Worked like a charm. Remember if any of the pins don't make contact then it wont charge.
Know this might sound goofy but same thing happen to me.
2 things that im pretty sure in some combo, was the issue
1. USB port got dirt/debris
2. The kernel I was running. Im 99% sure this was the issue all along. I was running abyss or something like that.
my nexus7 will not charge until it has completely drained....
I am aware of the current battery problems, but mine is a bit different....
Even after going to bootloader and choosing power off my nexus will sit on charge (wall) overnight and be dead in the morning, even though it was at 30% when plugged in....
The only way to charge it seems to be off my laptop. but even then it takes over a full day to charge.
If i hook up to laptop while runing it basically only slows down the drain but still doesn't charge up....
this is very frustrating, and i'm at my ropes end
would dowgrading to an older rom take care of this issue?

No solution, I'm afraid, I'm chiming in to say that I have also been having problems since the same time. For two days, I have been trying different combos of chargers, cables, and outlets, to see if other equipment is the problem. But all of it works fine with my Nexus 4. Mostly, I am experiencing that the unit says "charging" but the battery level is going down instead of up. I managed to get a full charge overnight by using an external battery that I got just for this type of emergency backup. After use, it is back down. This morning, third cable I tried finally seems to be working, for now. In 40 minutes it went from 63% to 65%. I am somewhat relieved but this situation is not normal.
I'm going to start reading through the forum to try some suggestions. I wasn't paying attention to updates. Has this problem been triggered by a recent update?
I understand some suggestions call for letting the battery discharge entirely. It seems that won't be hard to do. I can leave it plugged in and, as happened with most of the cables I tried, the battery level will go down to zero pretty fast. I'm really annoyed, but very happy right now that I splurged on an external battery.
Have you tried a new charging block... That would more that likely be your culprit.

I used three different chargers plus the external battery. Two of the chargers have two inputs (i.e., for Apple and non-Apple products). I have five different charging cords, longest is 6 ft and the others much shorter (two are from Monoprice), and one retractable I usually use in the car. I tried every combination I could think of between chargers, cables, input ports, and several different electrical outlets at two locations.
All the various combos functioned fine with my Nexus 4, the other device I have with me. None of them worked with the Nexus 7. All showed as "charging", but they weren't. In some cases, the numbers were going down quote rapidly. Goes without saying, when you're charging, it shouldn't go from 64% to 59%.
The thing that finally worked - with no hiccups - was the external battery. Since everything worked on the Nexus 4, it's quite apparent the problem is the Nexus 7.
Having said that, by this morning, things inexplicably changed for the better. With the device at around 70%, I connected one of the chargers and it functioned normally. Battery filled up within the normal timeframe. I was using it intermittently while charging, as I often do.
I'm glad it's working and very glad I have the external battery that can fill up both the Nexus 4 and Nexus 7 in a pinch. But I still think there's something wrong with the Nexus 7, and I'm not knowledgeable enough to dare try some of the more technical suggestions. Just the term "shorting out the pins" is enough to warn me that I'm not expert enugh to try anything like that. For now it works, I hope it lasts like that until perhaps I can understand the issues a little better.
I'm having the exact same issue as you guys and it has me stumped. On some days it'll work, others it wouldn't. At first I thought I could fix it by rebooting but last night mine just drained all the way down overnight while charging from around 50% and this morning I wasn't having much luck getting it charged using the 2 stock Nexus 7 wall chargers that I have. I'll try using an external that I got recently and hopefully that'll solve the issue for now at least.
Edit: Some people have had luck reversing the polarity on their charging block. I'll give that a go and report back whether it worked for me or not.
Edit/Update: Yup, flipped my brick around so that the big end sticks off the left side and it's at 32% now from 0% after 2.5 hours. You guys might have some luck with this too.
Nexus 7 fails to charge
We have two Nexus 7 in the house, one 11 months the other 6 months old.* The older one stopped charging just before our holiday last month so we took the other. It stopped charging while we were away.* Fortunately my wife had here Samsung Ace [mains] phone charger with her. This worked every time.*
Once home I checked the two Nexus 7 mains units and 2 Nexus 7 usb cables. No combination would charge either Nexus 7.* The Samsung mains charger would always charge both Nexus 7.
Solution:* Suspicious, I ordered an Asus Nexus 7 cradle while we were away. Any combination of Nexus 7 mains unit and usb cable charges both Nexus 7s on the cradle.
Conclusion: The USB socket on the Nexus 7 cannot take repeated insertion and removal of the cable.
Hope this may help somebody.
Yea I had the EXACT same story as you. I had for got to take my nexus 7 charger on holiday but I had my Samsung galaxy ace (s5830i) charger so I used that. when I came back and pluged In my charger It said that It wasn't charging so I used my brothers nexus 7 charger but still no good. It said that my brothers nexus 7 was charging but not mine and than I figured out what I had damaged... My nexus 7 charging port. I had proved this by comparing the the 2 charges and they where very different... Luckly It was still under warranty so I took it to (I cant tell you that). I looked all innocent and pretended I was new to this stuff and they then tried to charge it but no use so they replaced it with a new one but now I know not to put different chargers in my new nexus 7 and that goes to people out there as well

I have the AT&T version. 2 nights in a row I woke up in the morning and realized my phone was turned off, fully charged. I had a i717 (Note 1) and flashed the hell out of it through XDA since March 2012. Under 4.1.x and 4.2.x it happened to do that several times on my Note. So I started to worry that now I have the same issue with the S4. Once think I realized that is that I was using the same Samsung charger for my Note to charge my S4. I was also using a very long USB extension (USB 2.0 compliant). So I ended up using my S4 charger and its cable and problem went away.
At this point I realized I could have done more troubleshooting but don't have time. Just wanted to mention a few things. And frankly just a bunch of weird observations. We had a person using a long USB extension like mine at work and she started having PDF printing issues in Outlook. I know, random. We removed that extension and everything is fine. I used that same extension I used for my Note and my S4 to plug in the Toyota built-in inverter in the trunk of my FJ Cruiser so I could charge my Asus TF700 once and it refused to charge (I was using the Asus charger). If I bypassed the USB extension, everything is fine. So anyways, long story short and like I said without a real understanding on what exactly is happening behind the scenes, do yourself a favor and DO NOT cheap accessories or non-OEM accessories to charge your expensive device. I have done it for over 10 years and probably had less than 0.5% of issues, just like anybody else but sometimes things can happen. And it would be sad to fry your new expensive device with a $10 or less extension or cheap non-compliant eBay charger. My 2 cents.
By the way, I rooted the S4 and it doesn't have the latest AT&T OTA.
My phone is two months old and has ceased to quick-charge. Actually, 90% of the time, it will only charge when powered down. I use the factory charger and cable but get a message that I need to use the original charger and cable. Catch 22?
I bought it at Best Buy so I took it back to them this evening. My charger is fine as is my cable. Best Buy confirmed that my issue is a factory defect and politely sent me on my way. I take care of my phones if nothing more than the fact that I've had to replace micro USB ports in the past. The weird thing is that when it charges powered down, it seems to refresh to full battery very quickly.
Has anyone else had similar issues? If in fact, I do have to deal with ZTE, what has been members experience?
Thank you for letting me vent.

U can test your charger using USB volt amp reader on another phone which supports quick charging.
If charger works as it should then u need to test your phone with multimeter to see how much current it draws while phone is powered off without charger (battery only).
But that means you need to open 2 month old phone which i dont recommend if u have warranty.
Axon 7 draws about 2.66-2.68 amps while in quick charging mode. Volts i forgot but i think it was 6v. I'm not in shop at the moment so i cant know exactly.
But for amps i remembered.
Wallor77, thank you for your reply. My charger is in good working order. In fact, I have several 2.0 and 3.0 chargers. They all work fine on my Samsung Galaxy Note Edge. The Samsung displays "Fast Charger Connected" on the lock screen.
Now my ZTE Axon 7 will not charge while it is powered up. As soon as I turn it off, it charges just fine. This is really annoying!

If your charger and cable are OK, perhaps have you recently installed an application which limits the power. Such methods exists in some antivírus to preserve the health of the battery. It's just an idea.

Same thing there. If it charges normally while power off u need to see how much amps. USB volt amp reader is a good little device. I recommend for everyone to get one. It cost about 15 bucks. From there it's all about elemination process to diagnose proper issue

I second this. But $15?! You can get them for about $5 on aliexpress!
U have USB volt amp reader with both volt units, amp units, time duration and mAh over time charged value. But 15$ was about avarage price listing. I'm sure there is cheaper as well.
UPDATE: 6/2/17
I ended up sending my phone to the ZTE repair center in TX. It took about 3 weeks to get it back. There was no explanation of what was repaired and I received my original phone; not a refurbished one. All I know was that it was covered.

I am in the process of returning my 3rd Axon to ZTE. 2 of them have had this problem. It's definitely known because when I was talking to them and told them what was happening they just kind went "yeah ok" and fast tracked the whole thing. Thank god for this warranty, their quality control is ****e.

Last night, mine started doing this. It goes on and off about every two seconds. What's weird is it only does this with the quick charger. it slow charges when connected to a PC usb just fine. Its not the OEM charger either since my wife's quick charges just fine with the exact same charger.
Guess I'm going to have to call ZTE....
Mine suddenly stopped quick charging - I have 3 different chargers that work fine with other phones except for this one. And chances of all 3 of them going bad at the same time are slim to none. Tested different cables as well, but again same result. It charges with normal speed even when connected to QC3.0. Tried wiping cache. I think it's no different if I turn the phone off. Think it might be time to move on. Had it since December 2016, so I guess it's nearly 2 years old now. Still shame.

Quick update. Swapping batteries (OEM) hasn't helped. I wonder if this is software or hardware related
Let me add to this thread. I'm also not getting quick charge anymore for maybe a month already. Tried different cables, booting to safe mode, etc. There are few instances where i see quick charging but very rarely. I was thinking it's my usb port but I haven't opened my phone yet to verify.
I bought my galaxy note 4 in Saudi Arabia and It's been 6 years until my phone fast charging has stopped working. I don't have idea how did it stopped working. I've changed different charger together with different cable but nothing happened. A charger with same output and a cable that holds up to 2.1 A. Nothing happened. So I decided to go to service store and they changed my flexy charge kinda thing. And they said It's probably something wrong with the IC on processor or in the machine. My guess was fast charging doesn't work because the USB port has damaged *probably, so by replacing the USB port will work again. I kinda think that they replaced the sparepart with replica or I could say grade AAA and not with the original (which an average store can't provide such a thing). And yeah I go to an average store which I read on Google review with around 300 people giving 5-4 stars.
And yes I did go to Samsung store first and for some reason they can't fix my phone unless I accept my risk that fixing it will make the phone dead. And it cost higher for like over 50 pound. That cost could get me a new phone lol. Probably because I bought from overseas.
I'm frustrated with this issue regarding with normal charge I had to wait for hours just to charge until full battery. And yet while this battery comes with 3000 mAh, it depleted fast like around 6 hours while using productively. I admit this phone was the best at its generation. To be exact, I charge my phone from 0%-20% around an hour. So to go full battery, I must charge for around 6 hours or let it charge for the night.
My question is:
1. How does fast charging works? Is it really the processor that controls current output? Or somehow just change the flexy charge will make it works again?
2. If somehow I can't stand with this phone, which Samsung phone that actually more reliable and great than my galaxy note 4? (I kinda like Samsung A series, it comes with cheaper price with alot advantages but you guys can give me options)
I assume you already checked that. But just in case. You checked settings->battery->fast cable charging ?
Turn off and on...
And with something like this: https://www.amazon.com/gp/product/B07JYVPLLJ you can check that fast charging works. Should go to higher voltage if it works.
Fast charging can stop working because of the USB cable. I had to change cables a couple of times when fast charging stopped working with them. So I can imagine that USB port can affect it. It is controlled by the processor, which is why some kernels don't have fast charging.
You can replace the USB port on the note 4. It only costs $10 on ebay. But it is not an easy replacement, because you have to separate the screen. I managed to break my screen doing that.
You can also try to buy several replacement batteries for your phone, and an external charger. Then walk around with a replacement battery, and when the battery dies, pop another one in. And charge the old one in the charger. That could also solve your battery problems, because it could be that your battery is old. (and the standard battery on the note 4 is 3220 mAh, not 3000mAh. I saw a video on youtube claiming that fake note 4 came with a 3000 mAh battery)
The best phone to replace the note 4? That's pretty easy to answer - another note 4.
Some people like the note 9 very much. Of course it doesn't have all the features that our note 4 has! The LG V60 also looks nice.
Oh yeah, I also checked the settings and yet nothing happened. Thanks! I'll check that later.
So the fast charging controlled by processor. But is there any possibility by tiny little piece in a processor has damaged and that's why the fast charging has stopped? I did told the service store to change flexy charger as many as possible, but still it's not working. And I told them to replace my usb port on my stock flexy charger, and still it can't do the thing
Sorry I seem misspelled there, my battery comes with 3220 mAh, so my phone is genuine from Samsung.
Thanks for the advice! I somehow found desktop charger that it looks like this, www\amazon\com\Universal-External-Charging-T-Mobile-SmartPhone\dp\B00PC06MJ6 , do you think it will let charge?
