Fast charging stopped working

My S6 is 2 weeks old today and I noticed that fast charging (using adaptive charger I got in the box) has stopped working
Yesterday at work I put my phone on charge and went back to it after 20mins and noticed it had stopped charging.
I thought maybe it the 2pin plug point so I changed plug points and it starts charging.
Come back later and it stopped charging.
Changed plug point again and the same thing happened.
Getting irritated I put it on my wireless charge mat instead.
Today I decided to test the charger and low and behold it's now working but it's charging at the normal rate.
I tested this by using my old S4 charger and I got the same time to full message.
Before when I plugged in my adaptive charger it said fast charging now it just says "Cable charging"
Do you guys think it's my phone or my adaptive charger?
I don't have another adaptive fast charger to test with
EDIT: I was running XtreStoLite ROM, I used ODin and reloaded the latest AOD8 Vodafone SA firmware but still fast charging isn't working.

I'd say it's the charger. There have been instances of them shorting. The last Note 4 I had did the same thing.

Perhaps a silly question, but am I right in thinking that the fast charging only works when the battery is below 20% or so? I tried plugging mine in yesterday when at 40% charge and it just said 'cable charging' (using the out-the-box charger and cable)

When you use the fast charger, it'll say fast charging no matter how full your battery is.

Geez boet, how much does an S6 go for in SA?

I am having the same problem with my S6.
The fast charge doesn't work afree a week.
Last night I plugged in @ midnight with the original charger and cable at 5% and all apps shut down
It said "charging" and not "fast charging".
530am....only 97%.
This is pretty frustrating. It seems to have stopped in the last couple days.
Thoughts?

If you connect the USB cable to your PC and it detects your phone, it's proof that it's the adaptive charger. It happened to me on my Note 4, and I had it replaced with the warranty. Problem solved. Try it and you won't have any more problems. Garanteed!

Thanks - have now realised that I had to push the USB cable extra hard into the charger - that switched it from showing 'charging' to 'fast charging'

Oddly...when I connect it to my computer...it charges (slowly of course).
But the computer never detects it.

Update
@Biggenz the S6 32gig is around the R9000 mark
@BoondckSaint try another Adaptive Fast Charger, apparently even the Qualcomm ones work too. If it still doesn't fast charge take it into SCC.
@alanjrobertson my problem started out like that, I'd have to unplug and re-plug the cable in then it would work. Now more often than not it just doesn't Fast Charge
So, I took my phone in to Samsung Customer Care and after trying numerous chargers my S6 would just say "Cable Charging" and never show "Fast Charger Connected" in the notification bar.
They tested my charger on another S6 and S6 Edge and they both worked fine and Fast charge was working. Had the correct "Fast Charger Connected" in the notification bar too.
I had to leave my S6 there and they will repair it. The technician said it's either the USB connector is faulty or the mainboard needs replacing.
I'm abit disappointed now as my s6 is only 2 weeks old and it's already had to be booked in for repairs.

Hopefully no such issues for me - it seemed to be very much linked to the USB plug at the charger end not being the whole way in but will be keeping a close eye on it!

I hope its just the USB plug m8. I'm suffering without my S6

Have you tried depleting battery all the way down until S6 goes off by it self? Then charge it while is off all the way to 100% or leave it all night. Then see difference. Also one hint which is not quite related to your problem,but just for people to know. Fast Charging is NOT working from 50% and up to 100%. This is normal. So Fast Charge works from 0%-50%,NOT ABOVE!

The Samsung Care Center replaced the USB port on my phone and its fast charging again perfectly. Wasn't anything to do with the battery thankfully.
Before replacing the USB port the phone always showed "Cable charging" whenever it was plugged into the fast charger.
Now it shows Fast Charging in the notification area.

I am also having the same problem with mine it can be seen in odin but no mtp no matter which computer i use ... (yes drivers were correctly installed) also not showing fast charging with stock charger and about 4 different cables that i know work with it in the past. My phones been flashed will this void my warranty for usb repair ?

I took mine in and they fixed it. This was at the Samsung centre in my city. Took them a week because they didnt have any USB ports at their branch and had to wait for it to be couriered from Johannesburg

I'm having the exact same issue with my S6. Only a couple of months old and only showing Cable charging and intermitantly stops charging. I'd say definitely charging port. I've tried the samsung fast charger, the sony z4 tablet fast charger, my aukey quick charge 2.0 car charger and my aukey portable quick charge 2.0 portable battery. Bit annoyed

Same issue here. comp does detect it then it drops over and over. same with whatever charger im using or cord. 2 months old 920W8.
i see one of these in my future.........................

Yes. same like mine. Just push the cable extra hard into the charger. it works! thanks!

mine ose as you say but their was an inbetween stage off it booting in to the vertual reality app seriously anoyying but then just wouldn charge then started fast charging for a day then again to vtgear what ever its called then stopped charging completely n then would only charge at cable charge rate ( 4 hours till charged ) its currently at samsung repair center im waiting aan email

[Q] Charging--5sec-->Not Charging

My nexus 5 went to 0% battery one night and died. I tried charging it with 4 different chargers, some with usb some outlet and a wireless charger to no avail. I then purchased 2 new batteries and the phone was able to turn on with the replacement ones. However they would not charge. On the battery status screen it would go from saying Charging (on AC or USB depending on how i was trying to charge it) for 5~ seconds to saying Not Charging. The charging icon was still on the little toolbar battery icon but it would not charge. So those two new batteries are dead :good:. So I thought maybe software issue, I had enough juice to get in the bootloader and flash back to 4.4.4 which would still not allow it to charge. Then I started flashing to other versions and eventually back to 5.1.1 to no avail. I replaced the charging port with one from my brothers nexus 5 and it still would not work. My battery and charging port worked in his phone however.
Now I don't know what to do! This is the first phone I've really had to research about bootloaders and roms and stuff so I'm fresh.
TL;DR: Phone goes from charging for 5 sec to not charge with different software versions (4.4.4, 5.1.1 +more), with many different chargers (including one that came with phone), with new battery and new charging port.
Thanks.

Mine did that with a new battery also. The new battery was a dud--I contacted the seller, who sent me another battery, and that one does charge.

I've tried 3 different batteries including my brothers nexus 5 battery which charges in his phone so I am confident its not a battery issue now.

if the actual USB port is working on ur brother's and so is the battery, i am afraid then u have a bad Motherboard...
theres a Texas Instruments BQ24192 I2C controller chip, that is what regulates charging, such as voltage, etc...
if it doesnt even respond to wireless charging, that may be bad https://www.ifixit.com/Teardown/Nexus+5+Teardown/19016#s53734
that would be my guess....

Well technically it responds to it but it only lasts for a few seconds. Wireless charging and wired charging get a response from the phone by changing it to say charging on ac or usb or whatever but it just goes back to saying not charging after ~5 seconds. Is this still a bad mother board you think? Is it worth it to try and purchase a motherboard or just get a new phone?

Any solution for this? Came later but did come to this problem.

USB port damaged?

I have looked around on this topic before posting, but nothing applies to what im experiencing
Up until this morning, I haven't had a single issue with my USB port or charging in general.
I clean flashed Purity KitKat, flashed compatible Uber kernel and installed my apps as one usually do, and let the phone charge for a while. A few hours later, I realized my battery was at 0%. I started panicking, looking for a USB replacement part, which I found for about $12 on Amazon. I decided I would download GSAM battery monitor to see if there was an issue with my charging cable.
What I saw was the mA flow was acting erratic, sometimes shooting from -700ma (yes, that's negative 700) all the way up to 1800mA. Even by just rotating the screen, it would drop instantly. . The phone charges, but a little at a time. I disabled KSM and fast charge which seemed to have a positive effect.
I'm not sure what caused this, or how to fix it, but I've attached a couple pictures to give you an idea of what I'm seeing. If it is in fact the USB port, would using a Qi charger be a good option or should I just go ahead and dismantle the phone and replace the USB port?
Note: windows still recognizes the phone and I can send files from the computer, and the charging bolt is showing.

Have you replaced the cable? Far more common for the cable to crap out then the port. Cheap or broken cables will appear to work, computer will detect phone and even display a charging indicator but it won't actually charge. Had happened to me in the past.

Yeah I've tried numerous chargers including my car charger. They all charge, but it took 12 hrs from 0 to 100

Try flashing the stock rom to rule that variable out. If you want to be sure that is the usb port you could try with a wireless charger as it could also be the battery, you can find a new one at the same price range of the port.
It does seems a lot like what happened when both the stock charger and the cable were damaged. I tried to charge the phone and when disconnected it had less charge.

Anyone else having PD "Rapid Charge" Issues with Android Pie (9)?

Post Android Pie update I've noticed issues with the PD rapid charging. The original usb-c cable that came with the phone no longer works but I had no issues with the replacements but now occasionally I have to unplug/replug or reboot my phone in order for it to activate the "rapid charge" mode. I've tested this at various battery levels, power supply's and in general it doesn't seem to activate like it used to. My 3rd party Auckley charger was great but now I get more out of the 2.4A USB-A port than the USB-C PD/QC port.
I've heard the rapid charge feature hasn't been working correctly on Pixel's post update and was wondering if the causes were related? I'm hoping Essential responds to my concerns and if the issue is widespread issues a fix.

I did a clean install of P and I am not having issues.
Factory and 3rd party cables and chargers work fine.

Similar problem here except OEM cable works fine; 3rd party cables are having the problems you describe.

I suspect some 3rd party stuff is not really PD capable.

3rd Party VS OEM
I accept that some 3rd Party stuff may not be up to the same standards as OEM stuff but they (different USB-C cables) worked before the update and stopped after... If it was a single type/set up I would accept that as the cause but in this case it has happened with several different ones so I'm thinking it's a broader issue.

There is a handshake protocol and maybe there is a more strict adherence to the handshake?

I'm experiencing the same issue. Some PD chargers work; some do not. I just got my PH-1, so I'd never charged it prior to Pie.

Make sure your PD charger can do 9v and 12v for fast charge.

Finally yes I have this issue almost thrice a week dunno what causes it considering to factory reset.

got the same issue I have to plug in and pull out the cable one, two, three times until fast charging works!

Same issue... Using ampere to test and a few cables as well.. same issue.

I have some issue, how to fix it?

i'm going to revive this thread quick. Just got a Aukey PA-D1 (https://www.aukey.com/products/dual-port-30w-pd-wall-charger-with-dynamic-detect) and a matching type c-type c cable from them. plug the phone in and it goes from charging slowly, to rapidly, then drops completely, then restarts that whole sequence over and over. usually a restart will fix it, but its every time i plug it in. has anyone found an answer as to why this does this?
btw, running latest android 9, with june patch....

It happens to me only with power bank that supports PD.
It says charging slowly, normal, rapidly and disconnect.
Tried it with Galaxy s8, Galaxy note 8, lg g6 and it charge them great, without disconnect and with speed charge.
Also tried few cables, original cable and 3rd party who supports PD charge.

This has happened to me since I've owned the phone on one of my car chargers I own. It's just that one charger too. Issue has survived one RMA and multiple cables being used. In general I just plug it in and check in couple minutes to make sure it says fast charging and if not, unplug and replug it in.
Who knows if it's the charger's fault or essentials fault. I'm kinda leaning essential because it works just fine on my wife's pixel but the pixel is much more "understanding" in general when it comes to chargers (like it seems to fast charge on qc 3.0 too).

Anyone on Q beta seeing this?
I have been seeing this issue with 3rd party charger for months. I am wondering if anyone who has tried Q beta saw this issue resolved in Q beta.

My understanding is Quick Charge is broken...
So if the wallwart supports QuickCharge in anyway... It's trouble...
It has been that way for me on every iteration and security patch going back to 11/17 or so...
Somewhere... Way deep in the forum covered by ETA requests and useless banter... There's an article linked about how the PH-1 requests too much voltage from QuickCharge and forces it to reset...
This is an issue at the hardware level... And the only workaround is to make sure your charge brick does not support QC at all

Just figured I'd chime in as well. I'm experiencing the "Charging / Charging Slowly / Charging Rapidly" issue with my USB-C Car charger. One a Verizon branded and one an Anker branded. I know the Anker one is a "Q.C." one because it says it right on the device - but with the Q.C. enabled one, I only get "Charging Slowly" on it (so slow in fact, that the battery actually drains on the device). With the Verizon charger, I get the "charging loop".

Q beta 4 resolved this issue for me but it's back on both beta 5 and 6 . I've tried the OEM charger, a Nexus 6p charger, a OnePlus 7 charger and a Samsung Galaxy note 9 charger. They all cycle between charging slowly/ charging/ charging rapidly and not charging.

Has absolutely nothing to do with third party cables not being up to Power Delivery specification (at least in my extensive experience with this God-forsaken no end in sight charge speed bug. I've had absolutely asinine experiences with it myself where I've routinely {more than 25% of the time) had under 1000ma upon fresh plug in with battery below 30%. Also worth noting that I've seen the problem albeit less often pop up with USB a to c cables and ports as well.

Help needed or rather advice needed

So I think I have a faulty or a failing usb c on my phone. I can't seem to get to fast charge anymore.. the estimated time for a full charge now shows 5 hrs plus but when I wireless charger it takes 2hrs 30 minutes.. is it advisable to get a battery change and USB change. If so would I be able to perform the change myself.

I am assuming you have checked with different chargers. I had the same problem, turned out to be faulty charger.

I have the same issue although the other side of type c cable is not fast charging and when i flip it thats the time it fast charge but looks like my port is faulty. Tried cleaning it but still it stop charging/fast charging when i move the cable.
