Question about fast charging on the Note 9 - Samsung Galaxy Note 9 Questions & Answers

Hi...
For a while now I've had a problem with my Note 9 only displaying that it is regular charging when plugged into my fast charger plug and cable. I tried a numbr of troubleshooting steps from restarting, cleaning the port, trying safe mode, buying replacement fast charger and cable, factory settings, rooting but it still only showed as cable charging so I became convinced it was a physical problem with the port. Wireless fast charging continues to work as it should.
I recently installed AccuBattery and when plugged into my fast charger/cable, the charge current completely fills the the green bar to between 1800-2000 mA so now I'm beginning to wonder whether fast charging is working ok, but the phone is reporting it incorrectly.
Does anyone else know what kind of charge current the Note 9 should have when cable fast charging please? Also, just out of curiosity, what should it be when wirelessly fast charging too please?
Thanks for any help...

I know this is ridiculous question. Did you enable it in battery setting?

I started charging at 25%. With screen on I got 2700mah.
I left my phone off for 15 mins and stayed at that 2700mah average.
When I turned my phone screen on, I had 45% but screen on charge dropped to 1000mah.
If you look at the bottom of my screenshot, it explains why you need to turn your screen off to get accurate fast charge Numbers. Your phone might throttle the screen on charge if a certain criteria is met.

Once again. Did you enable it in the settings?
I am eagerly awaiting your response... [emoji3]

Thanks for the reply.
Hmmm the numbers you get do seem to suggest there is an issue with my phone. The screen off speeds are around the same as screen on.
Samsung quoted about £10,000,000 to repair as it's rooted and they have to replace the entire board to satisfy their warranty terms.
May have a go at replacing the charging port myself.
Thanks again :good:

I don't use fast charging, ever. So that's probably why my port still works. I have gotten so much dirt in it and cleaned it out it isn't even funny. So I'm less 6 to believe that fast charging is what ruins the port not debris.
A lot of people who use fast charging have the same issue as you-,it burns out the port.
Honestly, my advice is to love with fast charging over wireless and not spend a billion dollars replacing the port. Wait until it's time to replace the battery in a year or two and do it then. Fast charging over cable only saves you 30-40 minutes. I can charge and do charge my phone normally and it only takes around an hour and 40 minutes.

[HELP] Flashing Orange LED Light, followed by no light at all.

Ok basically I had my first battery drained completely (my phone was around 1 year ++).
I've been experiencing battery drains on my phone such that it is discharging faster than it chargers and I also realized that I'm unable to connect to the PC/ unable to mount SD card.
Knowing that my problem exists, I went on to a repair shop and they replaced my port for $S90 SGD. After replacing my port, I was happy that my phone can finally be connected to my PC without any problems..
Until one day, I realized my phone was discharging faster and soon it reaches 0% on my screen. I quickly plugged in the AC wall adapter and continuing using (by right it shouldn't go flat). To my surprise it went flat and I couldn't charge my battery at all, I was having the Orange LED light.
So I went to the repair shop again and they sort of bumped my battery up and charged my phone. Seeing that my battery discharges faster than it charges, they told me they my battery is damaged and so I went on to get a new battery...
New battery came, I plugged in, turned my phone on successfully without any problems. Battery was at 65%. I left it few hours to charge and WTF my battery turns to 19% and eventually flatten out again .
Now here's the thing.
My 1st battery, (Totally unable to charge, No blinking orange LED)
My 2nd battery, when I leave it for a few hours (I plugged it in and there's orange LED), and soon there's not even an orange LED light anymore.
I really do not know what the hell is wrong with my phone. I'm so disappointed. I just thought that it might not be my battery's problem because a brand new battery shouldn't have any problems..
Really need some advice noww :crying:
Gonna cry. Wth is wrong with my phone?!

You might have apps that are drawing too much current, a charger that's not supplying enough or is not recognized as ac charging.
Install current widget or something similar to see both how fast your battery is draining and how much current the charger is supplying.

My old Inc S did the same thing as what your describing, and the charger port was faulty. I had to wiggle the cord into the perfect position to get it to charge, and even then it only actually charged half the time. Got it replaced by bell.
When you plug your charger cord in, does it wiggle a lot to the left or right? As in more that it normally should?

The problem is I can't even turn on my phone at all to install any apps because my battery is completely drained. I just don't get it how come my phone drains the battery faster than it charges. Perhaps it's my charger not supplying enough power .
It's my second battery already and I'm now sure that it is not a battery problem.
Should I change an adapter (like maybe the iPhone adapter head) and use my usb cable to charge my phone. Will it provide more current

Well, I am not sure whether if it was charging port that was fault. It indeed charged when I tried my 2nd battery when it first came it had 65%. I went on to charge it and the percentage drops when it was charging (when the phone is off) . Perhaps it's not the apps that are draining all the current.
My phone is losing current... My 2nd battery is also completely drained off after sometime and I'm unable to on my phone. Irritating max.
My charging port just got replaced because I cannot mount my SD to the computer and I had it replaced and I was able to connect to the computer and LED indicates it charges.
What could be the other reasons that my phone is losing current? I'm not sure about hardware parts, but maybe perhaps it's the charging gland or whatever things inside the phone that is damaged?
Leave charger plugged in while light flashing. If the light goes off unplug and plug again. You might need to do a few times but the orange light should stay on eventually. Let it charge a while before switching back on. Good luck.

Sometimes won't charge if plugged in

I've had my N6 for about two weeks now, and lately I've noticed it doesnt charge once I plug it in, I'll go to sleep and a few hours later its still at the same percentage, I check the battery stats page and it shows "Not Charging" I unplug it for a few seconds and the Charging icon sticks as like the phone thinks its still "charging". Another issue I've noticed just now today, it says itll take 4 hours to charge from 56%! Only way for me to fix these issues it is to restart the phone and itll work, mind you this issue only happens sometimes. Although I will say I plugged my LG G2 into the Turbo Charger, so IDK if that affects the charger in any way?
Does anyone else experience this? If this is something no one has I'm planning to swap the device out for another one.
Running SinLess ROM v1.0.3
what charger are you using for your n6? and where are you plugging into? wall or usb?

This may seem obvious but try a different cable. I had a cable that, when plugged in, my phone would say is charging but doesn't actually charge.
I've had my nexus 6 for a couple weeks now and the first time this happened I was using a wireless charge so I thought I didn't have it placed on the mat right. But it happened again last night whilst plugged into an AC charger. The AC charger is an LG charger from a previous Nexus. When I look at the battery graph it just flat lines for the whole time it was plugged in.

My turbo charger is doing the same thing the OP said. We have 2 6's and it also happened to my wife's the other day too. I thought it might have initially been a cable too so I changed that out and it happened to the second charging cable last night as well.
Just experienced this
I use the turbo charger also and just experienced this. I was at 25 % after playing injustice (which just murders this battery) and plugged in the USB and I looked back 5 minutes later at I was at 22 %. So I killed Injustice and waited about 5 minutes more and I was at 19%. I had to reboot to get charging and after 5 minutes of charging I was at 29% so it is weird stuff.
I've been noticing this as well, but my charger is an aftermarket charger by Tenergy (Amazon link), and I'm using an aftermarket cable. Missed my alarm this morning because the phone must have not actually been charging, even though the N6 always shows that it is charging. I haven't tested it thoroughly with the stock charger as I keep that next to my workstation, but it seems that others are having this issue even with the included charger. Frustrating, to say the least.
Same thing with my N6 on 5.1. I would say that 20% of the time i plug in it shows charging but doesn't charge, just maintains the battery at whatever percentage it was when i plugged it in.
I don't have to restart but rather just unplug and re plug in the charger, then monitor for a couple of minutes to make sure the battery is going up and if so it will charge normally.
I also have tried a few different chargers including the quick charger that came with the phone. same result.
the same. here
I have the same issue while charging n6 with Motorola terboxharger ... But it takes 3 h while charging with any other chargers .....any updates !!!

Wow, same here.... only just started to notice it. Using turbo charger as well...however upon using a normal charger, it seems to always charge. it it something with the turbo charger?
Yea it seems to be turbo charger problem , but how come I bought it just one month ago !!
I started noticing the same issue recently. I'd say it started after upgrading to 5.1. I'm using the stock turbo charger. I found a workaround that, so far, fixes it for me (3 nights in a row at least).
After plugging in the phone, I notice the battery icon shows it is charging. If I actually go into the battery settings though, it says it is NOT charging. If I unplug the charging cable and plug it back in while still in the battery settings page (you know, with the usage graph), then it starts charging just fine up until I get a full charge. As long as I do this each time, I seem to get a full charge. Annoying, yes. But not as annoying as waking up to à phone that never charged.
Sometimes it won't charge when it's not plugged in either
For my N6 to charge, I need to push the TC USB cable a little downwards for my phone to charge. Sometimes, it doesn't even charge at all. I'm considering to RMA this, if I can do it here in Norway.
my nexus 6 has different behaviours, if I charge it when it is turned on sometimes it stops the charging and I need to disconnect and reconnect the cable and charging starts again, so i need to be careful because i can't be sure that my phone will charge completely if i leave it alone. if I charge it when it is turned off sometimes it starts to restart continuously showing battery in the screen again and again, without charging. hopefully this happens sometimes, i dont really like this bug, i spent so much money for buying it and i dont want to control if my phone is charging or not when I plugged it, i just want to put in charging and coming bac when it is flly charged.
RMA it
I hope the first thing anybody does is check the charging port and make sure there's nothing in there. Take a strong, sharp toothpick and carefully dig anything out that shouldn't be there. Pocket fuzz etc...
I am having this same issue, my phone is brand new yesterday, running 5.0, I have these exact issues, seems to be only with the turbo charger because I use a slow charger for overnight next to my bed and the battery was full. But I can't seem to make the percentage actually go up with the turbo charger without restarting the phone first.
Any more info on this very annoying bug??
can't seem to figure it out
i have the same issue - my N6 is a couple of months old and it started on an overnight (not) charge. Now it's happening 1 in 2 charges so it's getting worse. I cleaned the connection, tried different cables, USB chargers and plugging into the laptop - no dice. It's going back to Google - annoying...

Honor 4x charging issue

Hi,
My honor 4x has started showing weird kinda charging issue. It doesn't charge when power ON. When switched OFF it charges. But really slow. Believe me its really slow, like 1% in 20 mins or so. And not like the usually charging way too. The screen periodically shows up the charging icon every 8 seconds. Tried using different cables, different adapters, hard reset, wiping cache partition, cleaning the chargin port of the phone, but still no changes. Hope someone to help me with this.
Thanks
use ampere to check the current the phone charges at, could be a problem with the phone port if changing cables does nothing
I tried. But since it doesn't charge when it's on it didn't show anything. Ampere was showing discharging even with the charger connected.
Thanks

theres a problem with the charging port on the phone then, take it to a repair centre if under warranty
Just go and repair the charging port if broken

quick charge issue.

Hi anyone has problem with quick charge? I noticed that last night that when plugged in its charging in normal mode. I tried to move cable a bit in socket and plug again few times and after few attempts it worked as quick charge. I noticed that my USB plug seems quite loose in charging port.

The charging port (on the phone) is kinda shaky-but-tight fit on my phone too.
As soon as you plug in a charger, You see "Charging"..
And after device sleeps, you give it a few seconds and then you wake it up, it shows "charging rapidly"..
Additionally, I see this charging rapidly message - only when it is in certain battery charge percentage (withing 30-80%)
Which implies, in my opinion - that they have made sure that the device charges rapidly only when it's not working. (for heat issues, maybe)
If that's intended, I guess, that will really help with battery longevity.
Cheers,
Sony.

Ok just checked it and yeah looks like it. Yeah I'm just not worried about the port as it is shaky but yeah fit well. Thanks for help!
I have had an issue since 8.1. Returned phone to Nokia who and back with no fault found but was told to wait for July update or replace charger or cable. Definite issue.

Fast charging is gone

Anyone know what I have to do to get fast charging back? I have the option enabled in settings. The cord is good, my wife's phone fast charges just fine with it. I've soft reset the phone, cleared cache, and just about any other option I could find on the web. So weird cuz it was working fine not too long ago but just noticed now that I can't get it to work.
Try cleaning the usb port on your phone. i had the same problem, just cleaned it out with air.
Thanks but been tried that. I work in Audio/video so that was one of the first things I tried.

Are you able to mount the phone as storage on a computer, or able to access a USB with the OTG adapter? The charge port on this phone isn't the most robust and a few people have had problems with then failing.
No issues with any other stuff except fast charging. The phone charges fine but just say fast charging and takes forever. It's so weird cuz in my car my phone would barely charge when hooked up to USB in console, but then soon as I lost fast charging at home it started fast charging in the car. I just don't get it

Well luckily normal charging and USB still works so it's not the worst. At least your battery will last a little longer now?
My advice would be install an app like accubattery
https://play.google.com/store/apps/details?id=com.digibites.accubattery
It will show current when charging.
Fast charging being displayed by Android only seems to indicate fast charging is enabled rather than actually occurring.
I find when fast charging is occurring with standard Samsung charger, but not original cable it will show approximately 2800 mA.
It did seem to be below this rate a few months ago when ambient temperatures were higher and battery temp got above 36 °C
I also bought an unbranded charger cable that has an led that illuminates bright when high current charging and dimmer when charging at lower rates.
Probably defective . I've read issues on here about fast charging no longer working and it had to be repaired by samsung.

Ive had this problem with all my samsung phones since galaxy s8. I dont know why after some months the phone loses the ability to fast charge (it happened to my s8, note 8 and currently note 9)

I finally replaced the usb-c port
I had the issue that fast charging was gone and it charged very slow sometimes. I did many searches and did everything I could do. none changed anything. finally I went to Samsung and they replaced the port.

It was. Now I am a bit skeptical about this USB-C port thing. I take good care of my gears. Especially this one that cost me an arm and a leg. I want to do a survey if all the manufacturers' type-c port is prone to get damaged like this easy!
I would take your device to a Samsung Service Centre and let them take a look at it.
