Fast charging issue - Samsung Galaxy Note 9 Questions & Answers

So my note 9 (snapdragon) is never using fast charging and even if i manage to get it to give me fast charging it gives 1 hour 39 minutes to charge and takes 3 hours, when i charge by cable charging with disabling the fast charging setting it charges in 2 hours 10 minutes while it is cable charging not giving me fast, with the setting enabled it charges in 1 hour 59 minutes.
One side of the type-c never gives fast charging and the other side writes fast charging for 4-5 seconds then switch to cable charging and rarely doesn't switch but the charging time is 3 hours as i mentioned.
I tried everything possible other than trying to flash another software it is with the stock but unlocked.
I cleaned the socket, used 10 different chargers with different cables, wiped cache and tried safe mode and more.
Sorry for making it a long post but this problem is driving me crazy and i want to know can it be software issue not hardware because the phone is used for 2 months and the socket can't be cleaner, and if i flash the stock rom again will it be locked by T-mobile and i would need to unlock it again?
Thanks alot.

First of all, try to change the cable that 98% of the time is the problem when having these types of issues . Then consider the fact that the battery's temp influences the time needed for charging so if it's hot, software will decrease power in charging so that will give a longer time to charge. Even using the phone while charging or leaving apps in background will extend time for charging.

Samsung uses cheap USBc connectors that short out. Once you lose FC the only way to get it back is so get a new USBc installed by Samsung or a third party. This happened to me about 4 months after I got phone. I never fixed but I will never buy Sammy again. Its not your cables, its not the power cube, its the connector on the actual phone.

In every case, better Sammy's phone USB c connector then iPhones phone lightning connector because after a year you can't even charge the phone at all for having intermittent false contacts when you plug in the cable for the phones connector going bad....

It's possible the the USB C connection is faulty, it's also possible it's a faulty charger cable or even a faulty charger .
Eliminate one by one, buy a good USB C cable to check if that cures the problem, it often does.
Whilst as Tokedup says it may be the usb socket in the phone as according to his post he didn't fix the problem it's not possible to conclusively determine the cause.
It's unlikely to be caused by software, but high ambient or high battery temperature will lead to charge rate reduction
Maybe try an app like accubattery, this will show the charge rate in mA.
With a genuine charger and cable fast charge will reach a maximum of 2800mA

Well i tried everything you said with no success.
The problem is the phone isn't fast charging at all.
I believe it's the phone socket actually.
Thanks anyways

I already tried alot of cables and chargers so i am sure it's not one of them and now i am nearly certain it's the socket since you said it's unlikely to be a software issue, but i really wanted to know what could've caused it because i am sure i didn't do anything wrong.
I have been monitoring accubattery for a month now everytime i charge the phone. The mA is always between 800-1200mA and the phone takes nearly 2 hours to charge.
Thanks alot mate

just to be sure that it is not software related, remove all the battery optimization related 3rd party apps. clear cache and test the phone with stock usb cable and charger that came with the phone. what i had experience is that my note 9 SM-960F is sencitive to charger. if i use a third party fast charger or cable, it give me some sort of trouble like overheating or slow charging. so make sure you are using stock charger and cable that came with phone.

I wiped data factory reset and cleared cache and tried safe mode so i don't think it's any of that.
the last try will be flashing the stock rom again but i am hesitant because i am afraid the phone will be locked again by T-mobile and i won't be able to unlock it
Thanks

Why not get a Samsung wireless quick-charger and try it?

A wireless charger will not be faster than cable charge but I would get one so you don't wear out that port to where it doesn't interface with a computer if needed in the future. Btw all my new phones thats the first thing I turn off is fast charging it degrades battery more over time.

When I purchased my note 9 I did a post somewhere where I said the weakest link in this phone is the Charging port. And so right from the first week I got a wireless charging pad.
Also during the rainy season I keeps saying there is moisture in the port. Basiclly god help you if you live in a place with high humidity.
Like you this is the last Samsung Note I will buy in this life. My Audio packed up after the update. I suspect the over heating caused this. And their support is outsourced in India so they don't give a hoot about your issues.
To the OP.
Try a wireless charger if that fast charges Then you know its a port issue. If that also does not fast charge then its a chip / board issue.
I predict all note 9 users are going to see more and more problems as the over heating causes components to start to fail.
You can get a new USB port with flex cable for like 4$ on ali express go for it.

Veryyy slow charging

Went to a music festival over the weekend and used a portable charger to charge my phone, this is the last time I remember my phone fully charging. Once it died and I got back home, my phone would occasionally say USB connected and not charge until it said USB disconnected. Now it doesn't say that anymore but it charges ridiculously slow...
-Overnight charging I got 40%
-Left my phone for 3 hours and got 11%
-Use my phone while it's plugging into the charger and the battery still lowers rather than charging.
I've tried putting it in Ultra power saving mode and charging it while it's off but there is no big difference, I'm mad cause this cable is supposed to be charging it super fast.. Writing this post while my phone is plugged in I've already lost 2%
Nothing is wrong with my cord or the plug I am using, it's all the same stuff I have been using before. Could there be a problem with the port or something? Helppp
My phone is also in great condition always had a case, and just got it this past April
*also my phone is rooted so I don't think I can use the warranty

Are you sure? Cords die easily. Can you confirm how many amps the cord and the plug are allowing to be pulled? I've seen different phones pull different amps from different cords and plugs.
You can un-root and get back to a clean phone if you want to take it back.

If you have tried other cables and get the same result, you may have a problem. However I have seen cords got from .44a to over 1.2a from two different phones though.

check the power brick your using, if its the Samsung one that came with the phone it should be like 2 amps if I remember. id suggest using another power brick to test. also if you have a usb 3 super speed port on a pc or laptop sometimes you can use device manager in windows (start menu, right click computer, manage, in the window that opens click device manager, expand the universal serial bus controllers heading, check though any devices that say hub and go to their power tab) to see how many amps something is pulling from a pc usb. the other option is that you might have a defective battery but I don't know for sure. these are just some ideas that may or may not work for you.

Sounds like the portable charger might have been able to adjust amperage or voltage. If that's the case the portable charger could have damaged your battery if it was wrong amp and too high of amps. I have a portable charger that even changes voltage that could ruin a device too if not on 5 volts.

It sounds like it could be a battery problem. More likely, it could be a problem with the software. I would back everything up and flash another ROM or bring it back to full stock.
Option 1:
Install this app https://play.google.com/store/apps/details?id=ccc71.bmw
It will tell you batter voltage and charging current.
Options 2:
Charge with phone powered off.
Thank you everyone for the replies, my phones been getting worse to the point where it sometimes wont charge.
I think what im going to do is flash back to stock and bring it in to samsung or something , but also i heard a rumor that towelroot doesnt void the knox warranty? if this is true i may just bring it in as is...only becuase when i connect my phone my laptop wont read it anymore either, i havent tried if odin will but im assuming it would, i just dont want my phone to end up bricking because of the bad connection
This sounds like an old problem with Samsung phones, including the Galaxy S series. My original Galaxy S did this, my S3 did this, my sister's S3 did this. On those phones it was the charging port that caused the problem. My sister had her port replaced and her phone is working fine again.
Although I don't know for sure if that's your problem, that would be my first guess.

Yeah I'm pretty sure it has to do with the charging port, my battery is fine and so are my cables, and it randomly keeps saying USB connected/disconnected and won't change when it's "connected"

Replacement Battery won't charge

My replacement battery (looks the exact same, may be a generic product, though) worked fine for a few days, but then the phone started saying: "Battery can't charge right now," and the batter level just stayed the same with the cable connected. I tried various cables and adapters; the situation didn't change. I read that maybe a missing temperature sensor could be the issue. Does anybody have experience related to the issue?

Battery and rom are probably not the problem, i've solved this with replacement of USB C charging port in the phone.
I repeated the process with the same battery, and I haven't had problems in over a year. just took it out, put it back in, and that settled it.
why you replaced the battery, battery dead ?
what are the symptoms ?
because my phone is restarting itself , while charging it shows 90 percent and so on, its on when charger plugged in and if unplug it will stay on for few min and if i open app or camera it start reboot
I've had the same problem
I've replaced battery with an aliexpress one but after some charges problem came back and I think the problem was about I was charging my phone with the wrong charger (was using the Aukey QC3.0), so I've started to charge my phone only with the genuine charger but with another USB-C cable because the genuine one sucks.
After using the genuine charger the problem never came back and I left the genuine battery on It.
I've noticed that the USB-C port on my phone miss the original standard measures of height and width of the hole, so when I plug the cable It plays a little in the port and this is the cause I don't use the genuine cable.
Guy guys guys...
The answer is simple ^^ (ok not really )
Clean your USB C charging port of your phone... that fixed 3 to 4 times my charging issues, sadly after I had bought several cables /batteries...
So first think you must do before checking any other thing... is getting all the crap that the USB C charging entry point has after so many years/months of usage... it gets quite dirty.

Note 9 Charges Faster When Fast Charge Is Disabled

I've been having a repeatable problem. I have a Note 9 that will charge faster when I disable fast charging under battery settings. I tested the load being drawn with a USB Power meter these are the results I got.
Using a USB-A to USB-C cable:
When QC is enabled:
Phone draws 0.5amp charge, 10ohms resistance at 5.02V.
When QC is disabled:
Phone draws 1.2 amps, 3.9 ohms resistance, at 5.02V
I am using the same cable, same power bank. The power bank's USB-A port is able to draw ~1.9 amps at 5V, tested using a USB Meter and Load Tester that will put the USB under 1 amp and 2 amp loads at 5V, with resistance being ~2.7 ohms without the power bank turning off. I haven't tested the power bank at 9V, I don't have a 9V load tester
When I immediately switch from QC to non QC, the results above are repeatable.
Things I Have Done So Far:
Reboot Phone
Clear Phone Cache
Reboot Into Safe Mode
Try Different Charging Cables, Blocks, including OEM parts.
Every once in a while, it will switch back to being able to QC fast charge but it is random.
If I use a Power delivery capable block charger, it will charge at ~2750mA (I dont have other numbers like amps, voltage, or resistance, I'm still waiting on a USB-C meter)
My phone's wireless charging has no problem operating at it's max capacity
Any one else have this problem? Anything else I could do before I factory reset my phone?
I posted about losing Fast Charge thru the stock cable a while back and got no answers or a fix. I have not tried turning off the option to see if it charges any faster. It takes almost 2 to 3hrs to fully charge at this point. I'll take any fix or work around at this point.

Turning off fast charge made my charging a bit better. With Fast Charge (FC) turned on, I was getting 0.5amps (gave around 400-500mA). Turning FC off, sped up my charging by 50%, charging at 1.2 amp (roughly gave me 800-1000mA; Both charges were at 5V). Im able to charge at around 1000 mA with this setup, a little less than wireless quick charge. No idea why turning it off helped.
Another workaround that brought my charging speed WAY UP, to 2500mA, was buying a Power Delivery (PD) capable block WITH A USB-C to USB-C cable. I can get normal fast charging speeds with that setup.
I cant get FC with USB-A to USB-C cables, which is frustrating as most of my charging blocks are the regular USB-A input port.
Hope this helps you. 2-3 hour charge is brutal.
What's even weirder is in my car my phone would barely charge. But since I lost FC at home, it started working in the car. So in my car I can FC but not at home. I even tried the wire I use in the car and still nothing. Idk what is going on
Is it possible that turning off QC is turning off a regulation in the software to keep the battery from overheating? With this regulation turned off that would normally be on when quickcharging, the regulation is not active, thus causing the battery to charge at a less regulated speed, causing charging to be faster? Maybe there's a QC bug currently that's hampering it's full potential? What software version are you guys currently?
I just checked QC on mine on the latest Xfinity version and no matter what charger or cable I use with the function, it is working.
It's def not a software thing. I'm on latest October patch. Samsung told me that they have seen some issue with the charging port and once it goes bad there is nothing to do but replace it. They told me to bring it in to a store for repair thru my carrier. Haven't had a chance to go.

That what I was thinking. Something is actively limiting the charge coming in. Everytime I had quick charge enabled I've been monitoring the ohms and the resistance would automatically jump to 10ohms. Then I disable QC and the resistance automatically drops to around 6 ohms.

Yeah it could definitely be hardware related as well, due to each pin on a type c charging serving different purposes. There are two specific pins(I think it's two), that are responsible for enabling higher input of electricity. Couple years ago Google made comments about the cheap Amazon knock off cables and why they failed after a short while. Wouldn't surprise me if Samsung cheaped up for the cables and port on the device. I'll have to try and find the articles I read concerning the pins.
Here's a good start to understanding Type C.
https://www.allaboutcircuits.com/te...pe-c-which-pins-power-delivery-data-transfer/
Its the **** cable they supply with the phone.
I had all the same problems.
I noticed that when I turn off quick charge the phone can charge at 5v 1.7 amps. (USB doctor).
When I turn on quick charge it can only charge at 5 volts 0.40 amps.
The phone is trying to charge at 9 volts but for some reason cant so it goes into this safe mode.
I purchased a new Samsung cable it lasted for a week and developed the same problem.
A hint when it develops this problem Dex stops working.
I tried all kinds of cables. One Plus 5, and a few others. I finally got it to work again with my wifes one plus 6 cable.
Im now researching USB Type C ports and USB standard 2, 3, 3.1, 3.2
As well the quick charge tech used by Samsung. Its not Quick Charge 2. Its a proprietary standard.
So if your having problems with quick charge it could be due to your cable or your Port. Things very rarely go wrong with the charger. Also get yourself a USB Doctor. Its a big help. And only costs a few bucks.
Hope this helps somebody out there.
Right now I am trying to compare Note 9 vs Note 20 USB cable.

Galaxy note 9 fast charging problem

lately, somewhere after update to one ui 2.0 I started to have some problems with the fast charging.
as for now, the fast charging won't work unless it plugged to type C port in my PC that supporting QC3, and even that for like 1 minute max and that shorting my WHOLE pc's USB ports.
tried many bricks and cable supporting QC3 though the phone supports QC2, and nothing sadly made any change, tried as well on using the original brick and cable and still the same.
I've also been trying for like a week to clean the port with cotton and 70% alcohol and nothing changed
I tried to measure the Amps coming from the charger and got like 2 Amps max, although I remember when the Fast Charging did work, it gave like 3.3 Amps(all measured by ampere app)
I'm thinking it may be the port itself, but not sure about it
what do you think?
any help will be appreciated
Edit: I tried to wipe cache and charging in safe mode
Try wiping the Cache Partition in Recovery Mode.

This is a well known issue with all Samsung phones. They use the cheapest USB connectors on the market and they short out very easily. I lost fast charging over a year ago when my phone said the port was wet even though the phone had never been anywhere close to any water ever. The only way to get it back is to replace the USB port. With the phone being so old its not even worth the money to fix. Same ship happened to my wife's S9+ . I'm not buying another Samsung phone.
Thanks. I can see how a cheap port could be the problem. I've had this problem with my note 9 since day one. I can plug in a brand new cable that works great with somebody else's phone into a Samsung charger and randomly it will max out at around 750 ma or 1040, 1425, or up to 2275. This is even when the phone is at less than 20 percent, and the phone is not warm at all. I have wondered if a faulty temperature sensor has been to blame.....
What's odd is that i can take it off a QC or Samsung charger, stick it on a battery pack and it hops right up to 1200. Got a temperature sensor app and all is around 120 degrees F which I'm pretty sure is normal.
Do Not use 70% isopropyl alcohol on electronics, it's 30% water
Only use anhydrous isopropyl ie 99%
Use a OEM fast charging brick and cable. They're cheap, $20 for a Samsung 20w brick and cable.
Erratic fast charging and a rapid drop in battery capacity may indicate a battery failure.
Any case bulging is a battery failure; replace asap.

Battery/Charging issue

Hey everyone, how y'all doing?
I've got this problem for 2 months now where the charging has been super slow and no idea why. I am using the official charger and cable that came with the phone, I used my wife's s20's charger with same result and a third party charger with 3 different cables with similar results. Accubattery recorded that my phone's battery health is at 86% (3460mah) should I change it and lose my water/splash proof?
Oh yes I have flashed a few different ROMs (currently using Dr Ketan) with the same results except for evolution ROM, with the aosp ROM I was able to charge my phone from 14 percent to 100 in 90 minutes which is kinda weird...
Any advice would really help thank you

Get yourself one of those 2$ USB doctors. It will tell you how much power the phone is taking in. i.e. Fast charge should be 9 volts at about .8 amps and slow charge 5 volts at 1.5+ Amps.
Make sure your port is clean and moisture levels are low i.e should be below 80%.
I had this problem once when moisture was over 80%. It then went away. But at that time the phone will warn you about the extra moisture. It will say Moisture detected in USB port Fast Charging disabled.
The second time this happened was after the update to android 10. Had slow charging and overheating and audio acting up but that went away after re-setting the phone a few times and clearing cache.
The latest update to Android 10 seems to be causing a lot of issues with Display, Audio and overheating / slow charging. My audio chip finally stopped working. And the phone is now with Samsung.
My 2 cents if you see overheating and slow charging. Stop using the phone while its still working and take it to Samsung. Because if you continue to use it something will fail. And Samsung will want to give you a big fat bill to change it.

Get yourself one of those 2$ USB doctors. It will tell you how much power the phone is taking in. i.e. Fast charge should be 9 volts at about .8 amps and slow charge 5 volts at 1.5+ Amps.

Thanks for the advice and I'll see to it. It's just yeah it seems like after android 10 things have been degraded
So apparently turning off fast charging in options gives me a faster charge time. With fast charge on it takes from 7% to 100% in 3 and a half hours and with fast charge off it takes 2 hours only.... Maybe my fast charging "chip" / "module" is broke?

Have you tried installing the stock OS back onto your device?

Yes I have tried, the June update one and got the same results. I even formatted everything and went bone stock with the same results. I'm thinking of using some contact cleaner on the usb port but hesitant to do that...

Unless you see something in there I do not advise poking around inside.
I suspect your problem is that the Samsung USB cable packed up. And your trying with all kinds of cables and chargers. Go to a Samsung Store and ask them to check with a Samsung Cable and Charger.
I went thru this circus a few months back.
The only solution is to get a Samsung Charger with a Samsung Cable.
Then make sure fast charge is on. For wireless and wired charging. Wipe your cache and you should be ok.
I have seen way too many damaged USB ports from people trying to clean it. When there was nothing in there to start with. Use compressed air. If you see something in there.
