Hey guys, I created this thread to chronicle my attempt in fixing my Galaxy Note's broken USB dock connector.
The problem: The phone charges only when off. MTP/USB mass storage won't work. On some roms Car mode wackiness ensued. It seemed like it was possessed; exactly like another persons detail of the problem.
Attempt to fix it: Contacted three wholesalers in China at Alibaba.com for the dock connector for Galaxy Note. Waiting on response right now.
So far I have eleminated everything in my troubleshooting. I've tried multiple custom roms and went and tried two different stock roms with no luck. I also have tried plugging in different kinds of usb cables. I also tried plugging them in different computers.
Anyone can post they're problem-->solution here for future reference.
I found this on google and I thought it was very helpful. HERE IS THE SERVICE MANUAL FOR GALAXY NOTE:

I am afraid there is no solution for this type of behavior at this point. I am too had the same experience.
I am awaiting for another responds email from Germany(where my Note came from) to send mine in for a repair. Until then, I can still use my Note with external battery/charger that I got from Amazon.
good luck-
Are guys plugging the cord in upside down or something? Ive had galaxy s, sgs2 and now note since release day and havent experienced this issue.
GALAXY NOTE
Did you guys try use difference charger? I face the same problem once where the charging mode keep changing to dock mode on and off while charging. After i change it use others charger (spare), now everything is ok.
My theory is that the charger started to malfunction n produce too low or too high voltage which trigger the dock mode..my 2 cents.. ;P correct me if im wrong..

I can assure you it's not the charger or the data cable, as I have plenty laying around. My money is on the logic board.

After having 2 SGNote units being bricked and (luckily) replaced with a new unit everytime, I found that the root cause for the SGNote being bricked is a weak USB interface and protection circuit. At first I thought I just messed up the rooting process that's why I bricked the device. When my 2nd replacement unit also got bricked, I traced back that the only common denominator was a rogue iphone charger that I used to recharge the device. Knowing that the weakness of the SGNote is the USB circuit, I'm now careful to use no other charger but the stock charger that came with the unit.

I strongly believe that the Galaxy S2 USB problems are of similar nature and the solution was to replace the USB dock connector. This gives me a lot of hope since it's easy enough to do. There is no soldering involved AFAIK since it just came off during the Galaxy Note teardown video on youtube @2:28 and @3:36 (ttp://www.youtube.com/watch?v=UFDr3PQMTxw). Correct me if I'm wrong.
its definitely a hardware issue and has been traced to the usb port inside the phone. I have the same issue and I am also waiting for the part to replace the damaged one inside my phone.
here is what I am doing to make my phone function-able:
When you connect the usb cord to charge the phone you have to press it down hard and then slide it out. this will temporarily fix the physical usb port pins and allow your phone to function normally. you have to do this every time when you connect and disconnect the usb cord. I will use my phone like this until the part becomes available to buy. I have a feeling, this phone is very delicately designed and can get bricked all by itself.
My note does not charge with Three of my HTC chargers neither does it charge with another car charger.but charges fine with the Samsung charger.has sometimes issues with otg with Samsung otg cable and another otg cable. Even today when I used a Samsung otg cable to connect my note with a Samsung galaxy s2 via a Samsung USB cable, the otg features did not work, the s2 just said mtp and note said unknown device connected! So there are issues with this USB on the note.
I saw a youtube video for Galaxy S2 where he suspected that it was a malfunctioning USB dock. He replaced it and all the symptoms were gone. I'm really going full press on this and hopefully I can help myself and others who have similar problems. I've read up on USB problems the last 2 days from Galaxy Note users and Galaxy S2. They are very similar in design other than the screen/stylus.

Please keep us updated on your progress.
BTW to the folks having USB issues, are you having unusual battery drain? What other quirks have you encountered?
Has anyone compared the shape of the USB dock connector for Galaxy S, Galaxy S2, Galaxy Nexus and Galaxy Note? I wonder if they are all the same shape and if I should try and look at replacing that part only? If it is the same then I will get this http://cnn.cn/shop/samsung-i9000-galaxy-microusb-connector-p-10745.html since it's cheap and I've got nothing to lose if it doesn't work.
Looks like we have a new design flaw here..so, how long does it take for you guys to experience this problem from date purchase your note?
Mine already 1 month purchase and not having this problem.

I fully agree that it is a hardware issue. Samsung should come up with an extra dongle or maybe a protection circuit integrated with the USB cable that should be used in conjunction with the SGNote. Otherwise, this issue will just keep on repeating and they will end up with a bunch of bricked units on their hands.
If only I didn't like the display on this device, I would have opted for a change item instead of a replacement unit.
I still have the rogue iPhone charger and when I use it to charge an iPhone it keeps on repeatedly bringing up the charging battery icon on and off but it doesn't destroy or brick the phone. But when I connected it to the SGNote, it bricked it. I did it on 2 units. And it will surely brick any other SGNote unit I connect this charger to. I'm willing to demo this to Samsung to prove the point of their weak USB interface circuitry.

Like you I got the Note for the screen size because I don't like to read in small screens. I haven't had a phone in 6 years!!!! I've seen phones come and go. The screen size of the Note made it comfortable enough to read anything (PDF, comics, web pages, ebooks).
How sure are you guys that it is indeed the USB circuitry and not just the metal dock? To be honest I'm not sure right now.

Oh my! Looking at the charger flex assembly pictures, all I see are a bunch of passive components for protection. I see no active components on this board that would likely be used for over-voltage or over-current protection. I'm not sure if it's on the main board though. But normally protection circuitry are placed right next to the connector for them to be effective. There seems to be a lot of space on the board for even a single-chip USB protection circuit but the space hasn't been utilized for such.
I'd be willing to bet you that your problems will still be the same even after replacement of this flex assembly.

For me, about 5 minutes after I plug-in the rogue iPhone charger... I did it twice... and luckily, since I still have warranty, I got both units replaced.
I strongly suggest for everybody not to use any other USB charger apart from the stock charger that came with the SGNote. Of course, this excludes plugging it into a PC or laptop as they should be fairly safe and well-protected (at least for name-brand units).
If you're going to use the stock charger, I would recommend plugging the USB cable in the charger and plugging-in the charger in the wall socket first BEFORE plugging-in the mini-USB connector to your SGNote. This minimizes the chances of having voltage spikes being transmitted through the USB connections into the SGNote, especially during the actual plugging of the charger to the wall socket. This is to be on the safe side in the case that the stock charger design is also flawed and doesn't prevent transients from reaching the load unit itself.
Is there a website or something from which we can call Samsung's attention on this matter? If indeed transients are the cause of the USB problems then all they need to do on the SGNote is to redesign the USB board assembly and stick it into units that have not been affected yet. This entails a product recall or as I mentioned in my previous post, maybe to offer us SGNote buyers a dongle or a USB cable with the protection circuitry.

Yup on the service manual and on the links to alibaba that you provided on your previous posts. I looked at both sides of the sub-assembly and only found passive components.
Well I'm using a 2 amp charger from ebay for charging downstairs; a HTC 1 amp charger in the bedroom; the 1 amp Samsung charger in work, but I also plug it into the 800 mah charger that also charges an extra battery in situ. ... she's till working fine.
Right now, usb mass storage or MTP is totally non-functional for me. I'm still glad USB charging is working. I hope that parts holds up till I get a replacement for it.
Thank goodness for wireless and FTP!
Hi everyone,
First of all, I apologize in advance,
1. Because I know this isn't a tech support forum.
2. Because I don't contribute and help out as much as I should.
Coming here was a last resort, I don't consider myself a noob, but I'm really stuck here.
Please note that I appreciate every single response, and I will donate if anyone can give me a fix.
With that aside, let me get started
__________________________________
Okay so about a week ago, I accidentally bent my charger when it was charging my note.
It didn't charge at all that night
That morning, I blew into the charge port on my note, suspecting that dust may have been the cause.
Somehow, that helped, as my note charged fully that day, in about 2-3 hours
Then I tried charging it the next night.
It charged incredibly slowly, reaching about 70% after 10 hours charge
The next few nights were similar, but reaching no more than 40% charge after 10 hours.
It got progressively worse, it would only charge if I applied pressure to the mini-usb,
I looked around this morning, and stumbled across another guy with the same problem
(see here http://www.galaxynoteforum.net/galaxy-note-help/charging-port-issue/ )
He advised,
"Well I have figured out the issue. If you look into the charging port slot on the phone you will notice a small thin flat piece of metal which inserts into the charger. That was slanted and angled downward which would not let "ANY" charger or docking station charge correctly also causing it to drain the battery. Contacts on this piece and the phone were to close causing a minor contact draining power. I used a precision flathead screw driver and lifted the piece slightly and now works fine"
So I tried that, and it seemed to help, as the note began charging, (extremely slowly, reaching about 30%)
Then I tried pushing that "thin flat piece of metal up even further"
However, I went too far, and I couldn't fit the charger into the charge port.
So I tried pushing it back into the centre but I may have damaged one of the pins in the charge port (inside the phone)
I seen a little spark, and the note turned off.
I tried switching it on, and managed to boot to safe mode (no idea how)
So then I tried charging it, I applied pressure and managed to get it to start charging. (thank god)
This was about 30 mins ago, it looks to be holding the charge at about 20%, but it's not increasing
-----------------------------------------------------
I suspect one of the pins in the note charge port was snapped off.. although I'm not sure.. (it appears to be the one on the right)
1.Does anyone know how many pins there are on the charge port inside the note? (is it 4 or 5?)
2.What should I do?
If I broke a pin, it should not charge at all, right? (but it seems to be charging)
3. Do I need to replace the charge port, if so, how much would it cost?
4. Would I be better off getting a charging station, and charging the battery using that
5. Should I try moving the metal strip again? (inside the charge port of the note)
oops forgot to mention, when the problem started, and the note was slow-charging, an audible buzzing/humming could be heard in the wall outlet
also, I'm using my original samsung usb charger, not a generic one, and I'm charging directly into a wall outlet.
------------------------------------------------------------------
Thank you for taking the time to read this, I really appreciate it, and any advise that you do offer.

Here my tipp: You can go to a service center, maybe they even repair it under warranty. Or you can order a new micro usb port and replace it. Google should help you to find a seller. Depends on whether you feel comfortable enough to replace it yourself or not. Oh one more thing, I would stopp using your Note to avoid any further damage.
Sent from my Galaxy Note running ICS
there are 5 pins on the charger slot, 4 I believe are for data transfer and the 5th being the one that draws power (charges the phone)
Have you tried transferring data from PC to Phone and see how that pans out ?
Its possible to replace the USB port, Ive seen a few threads about this on XDA, A quick search should chuck out some results.
But as mentioned above, Try to claim under warranty first, if you have it, or pay the Service centre to do it if you dont feel confident enough to do it yourself.
I think I recall someone with a similar issue and it cost him / her $60 for USB replacement (convert that in to your currency)
If you have a friend with a Note or a phone that fits the Note's battery you could always charge your battery in that phone and place it into yours until you get it fixed.
IF YOU MUST charge your Note ( you could if you intend to get a new USB slot) I would suggest to charge only via USB - as in charging from your PC / Laptop / TV / PS3 etc. As this will not draw as much current as it would coming directly from the mains supply!
Good luck on getting it fixed, And please keep us posted with the results !

Thanks for the quick reply!
First of all, I can confirm that no pins are broken or bent, everything looks normal, it also seems to be charging better, as I centred the metal strip in the charge port.
As for warranty, well I didn't purchase any extended warranty or insurance, however, the standard warranty lasts 2 years.
Unfortunately
The Repair Warranty Exclusions are as follows: (i) Subject to the inclusions of the applicable manufacturer's warranty, a mobile that has broken down or is damaged as a result of: (a) abuse or tampering, (b) electrical damage, moisture, dampness, oxidation, corrosion or food, dirt or liquid ingress (c) accident, neglect, impact, actual or attempted theft, fire, power outages or surges, or incorrect voltage, (d) transportation or packaging (e) removable batteries or damage caused by battery leakage
Basically, the only thing that I'm covered for is "handset breakdown"
My phone is in perfect condition, and no pins are broken or bent (as discovered on closer inspection)
So do you class charging issues as "handset breakdown" or not?
I may purchase a new charger, just in case the issue is with the charger, and not the phone,
What d'ya think?
Thanks again for the quick replies azzledazzle & nipuna, I didn't notice them until now,
Yeah I'm 90% there's no damage to the pins on the charge port, and it seems to be charging now, slowly at least,
I've centered the metal strip as best as I can, (inside the charge port)
I'll leave it to charge now for a while, as I'm not sure if it's fixed or not
Then I'll try another charger if it doesn't work
If all else fails, I'll try getting it repaired under warranty
(although that's more of a last resort, as it will take a few weeks to get my phone back)
does anyone know if the standard galaxy s2 charger will work on the note?
I don't have it on me now, although I could borrow it from a friend
I know its an official samsung charger, although not sure if it's the usb or the other kind.
I'll let it charge for a while, then I'll try transferring data from the laptop, to make sure the pins are fine,
thanks for all your help everyone,
1st of all: if you go poking around in the usb port with a metal screwdriver, take out the battery first. Not only will it avoid shortcutting and maybe blow a fuse inside the phone, but it will also protect you from an exploding battery when shortcutted !
S2 charger will work

I bought my S6 about 1 month ago and since then I have charged it with different micro usb cables.Afew days ago the phone was showing random "top up's" on screen like "power sharing connected",Samsung VR" and yesterday I couldn't charge my phone .I have been to Samsung Care shop to see what's going on.I left it for 1 day to fix it.Thanks God I didn't root it and didn't break the knox to 0x1 and them done the service for free under warranty for 2 years by Samsung.The Engineer told me to not use foreign micro usb cables to S6 because it's different micro usb and it will break.I hope someone will listen to me and to not do whst I done.The normal price to replace usb port to S6 is £253 so be careful guys.

Any cable that is not Samsung S6/Egde original.Its need to be compatible with S6
USB is a standard and the connectors are the same but I agree that some cables might have different connector covers so it might push agains the case and force the usb connector.
On a side note you should black out your information. I can see your name, address, all your phone numbers, your phone serial/imei too...

Sorry that's crap.
A micro USB connector is a standard part, unless you are buying horribly cheap junk maybe, they will all fit fine.
I have used several cables and not hurt the phone at all.
I buy a kignstons usb duo 3.0 64gb for 22 dólars.... that's means I can't use in my S6?
using my OTG usb stick with the S6.... Works. It's a bull**** comment from the repair service...
Lets just hope this won't be an S3 disaster where the USB port was a weak point. My GFs S3 had the S3 USB port problem, where it would start charging very slow due to bad USB port and a week ago, stopped charging completly, unless kept in a specific angle. On my S3, all cables worked that I had, for hers, only 1 cable made a "good" connection.
the repair service has got it half right
regarding physical damage to the port:
what you want to make sure is that other USB cables don't cause stress to the USB port... as you may have noticed, different microUSB cables have different size plugs (the same microUSB metal connector, but the plastics surrounding it are different sized)... we must make sure our cases don't interfere with the cable plug (many case manufacturers only design their case with the original samsung cable in mind, which might not be big enough for plugs like the monoprice microUSB ferrite cable, which has a large rectangular plug)
all the above is moot if you don't use a case
edit: and update with a video to explain what i was mumbling about
regarding electrical damage to the port:
you'd be safe to stick with OEM quality USB AC adapters or other big-name (Anker makes a lot of them) USB AC adapters... but STAY AWAY from those no-name cheap china adapters!! those have poor power filtering, electrical noise, poor grounding, etc....
Just because it fits in the same hole and has the same pins doesn't mean it's compatible. Using a cable not made for fast charging on an S6 would be like trying to jump start a car with a lamp cord. It could overheat at the cable, connector or battery. That's why using the wrong charger or cable voids most warranties. Here's one such case, if you are interested:
http://forum.xda-developers.com/oneplus-one/general/oneplus-one-melted-t3008581
The OP is lucky Samsung honored his warranty.
I call BS. MicroUSB is an industry standard. If they were not compatible not only would they not be able to call it that, but they would be subject to sanctions for violation the requirements for using standard cables ports of which the MicroUSB is currently is.
While you might not get the faster charge if you don't use their cable and their charger unless you are using very poorly made cables you will be just fine.
I charge my s6 most of the time with a BlackBerry charger for one of their discontinued tablets. 1.8A with 6ft fixed cable, I have 6 of them, they charge everything from tablets to phones. The white "short" Samsung cable and charger is in the box.

It is a valid warning, I live I EU and I think that I can trust shops here to sell me good product ... I use original mini USB cables for all my gadgets and all of them are the same but even dispite that on my ex phone I had flimsy connection due to some damage to USB port even I used original cable and I give credit to my using the phone during charging and the fact that most of us use our little finger as a stand and then the USB tend to move a bit and damage is caused...
The truth is that not all are the same as some are faster and some are not ... But in the meaning of just the metal part of actual connector they should be the same by law if EU ...
Considering that in mind the only rule in buying accessory like cables should be are they been through a regulatory channels ....

I use my Nexus 6 charger & cable works fine. Very fast charging on both. Buy OEM cables, a bit more but no headaches...
I use either Qi charging or at home I have uGreen mUSB cables.
No issues with any.
Nor have I had with any phone I've owned.
And I've owned a LOT of phones (probably change my phone a minimum of twice a year)
This is not correct, at all!
Micro USB cables are a standard and every cable should be good to use in the S6. I use 3 cables with mine: The original cable, my Tab S cable and some cable I have for years (from an Huawei X5 or a Moto G, not sure) and haven't had any problem what so ever! As said before, just stay away from the 0,2€ chinese cables.

Why did that happen to me then?i never used chinese cables.i have been using my genuine s4 and htc cable and the damage happened for 1 month after i bought it.so that will happen one day to someone else.if u have a look to the s6 usb port its a small difference between the other phones.it looks thinner.The engineer that fixed my phone advised me to use just S6 genuine usb to my S6.If you know all the Samsung S series have problems with usb port.
Hi Everyone!
Unfortunatelly My x720's USB connector burned few weeks ago during fast charging.. It is burned, the connector is fuzed and I feel the burning smell, but it was already too late.
So the usb port got unusable, I can not use it for charging, and I am not able to connect to my phone!
I wanted to buy a new USB flex board but unfortunatelly there is no full (factory) version on the market!
I searched it many hours on the net, but there are only cheap ( remanufactured) version of it.
They have many missed parts, just have their solder points on the board, so these do not support OTG and fast charging.. I can not understand why can't make full version boards for a higher price, these versions are unhelpful items.
https://ibb.co/kYypx8
https://ibb.co/fnH4VT
https://ibb.co/fZM9x8
So I bought only USB C connectors and I will try to replace it on the original board!
I thing it will be a hard work, but I hope it will succeed.
If not, I have to buy a used phone for parts, and I will take out the USB board from it.
As I see, the X722 have the same flex board!
So I would buy a hard bricked x722 for parts for a good price!
Just very important to me that its USB connector be in a good condition!! Do someone would sell it??
I know unfortunatelly there are lots of users who have hard bricked dead x722...
So if you read this lines and you can help me, please write me, and I hope we can make a deal!
Thanks
Daniel
Hi, exactly the same happened to me, the USB port of my leeco was burned. I do not know if it would be because of the usb cable c stock that brings (bad quality). But you'd be surprised if I told you that, shortly after the usb port c burned down, I looked more closely at port C and there was melted black plastic on the pins of the connector. Then clean the connector with a fine needle (carefully), getting rid of the plastic, the remains are cleaned with cotton and a little isopropyl alcohol (which leaves no traces when it evaporates). After doing all the above, I was surprised when I plugged in the headphones and it worked, in the end I tried another cable type C first with the PC and it worked (it was recognized by the normal PC), then I took a chance with another charger I had at home (not the Leeco charger) and it worked ... I had no problem loading it. You could try it ..!

Hi
@Kener97
Thanks for the response, I would try it, maybe it would work for me as well, but it is pretty melted..Unfortunatelly I have already disassembled the phone. I did not have another cables, but now I have two good quality fast charger USB C cables, but now I already can't try it! I happy that you can use your phone after the accident. Yeah, you're right the original cable has very bad quality. I had already thrown it into the trash.
So I decided If I have already disassembled the phone than I will try to replace the USB C port in the next week and then I'll se what can I do.
@tsongming
Thanks for the links, but as I wrote, these USB boards unfortunatelly are not the original items just cheap versions with many missed parts! Check the images!!
You can see teir solder points on the boards. So these don't support OTG and fast charging... Only the normal charging without communications. These are not an option to solve the problem. Maybe if I would replace the missed parts from the original board if the connector replace won't be suceed.. )
I will write the result!
Anyone, any other solutions? Or anyone known where could I buy the factory version boards?

Daniel

I don't know, but the x722 and x720 is the same at the USB port and the poor quality USB cable as well!
I just recommend You don't use the fast charging especially don't with the original cable!

Thank you for the answer. Do you think the problem is the whole charge or Just the cable? Is It ok to use fast charge with third party cables?

The cables are notoriously bad, one of my x727s was destroyed by a bad cable. Fortunately, Amazon exchanged it for a new phone.
We have 4 Leeco phones in our house. I have replaced all of the USB cables with highly rated cables, that have a replacement guarantee.

Although some people recommend also switching the charger block. I don't agree with them, and think that is overkill. Its the stock cables that are garbage, not the the charging blocks.
We have four of these charging blocks and no issues with any of them. In fact, in late December, when the X727 that I returned had its usb card burned. My dad ( a retired electrical engineer) took apart one of the blocks and found it well constructed.
Next, Leeco charging blocks are approved by and meet Qualcomm standards.
https://www.qualcomm.com/media/documents/files/quick-charge-device-list.pdf
If there was an issue with the charging blocks on a large scale, would they still provide this publicly available list? No, I don't think so.
Should you decide to go ahead and replace the adapter anyway, The pdf list has a section with Qualcomm approved chargers under the "Premium Power Banks" section

There are plenty of people with bricked X722's, go to the X722 unbrick thread and message those people, maybe some on will sell you their expensive paperweight for cheap.
If you live near a large city there is bound to be a shop that does repair at the component level. perhaps they could fix your damaged board or as you mentioned transfer the chips from the old board to the 3rd party board that has missing chips. The issue is that some of those chips are likely fried.

Hi!
No, only will work the slow charging and USB communication with the cheap, useless USB flex board!
But there is a solution, to get a new original x720 USB board with all functionality!
After 3 months and Iots of time what I spend on the net, I found TAOBAO chinese site, and to my surprise some seller selling the original version board there with a good price!
Use the Crome browser with built in translater!
Only one problem, TAOBAO is a chinese "domestic site", and nobody ship to abroad.
But I did not give up! And I found the final solution, that's Yoybuy! (Yoybuy.com)
Yoybuy is a forwrding site!
You can buy everything form chinese sites helped by Yoybuy, for a cheap price!! From Taobao or many chinese site and you can use it English.
Just register at Yoybuy and copy the Taobao item's link to Yoybuy and they will buy the items, what you want! You can pay by paypal as well!
I hope I could help you! My phone is back to life, and it is like a new one!
Regards
Daniel
PS. Definitely buy a new good quality USB C cable for charging ( I recommend You the Oneplus DASH cable) to stay the USB connector intact!

I think you make a good point about the the LeEco charger. Precisely, it is the cable that is the biggest culprit. I recently bought a x720 and had it for a week charging with an old charger and cable of my le 2. One day i couldn't find the le 2 charging cable so I decided to use the one that came with the pro 3. Just seconds after plugging the cable in I smelled burning plastic and could see smoke coming out of the usb port. I removed the cable and could immediately see that it had melted on the pins close to the edge. Funny enough, if i plug this burnt cable on my le 2 it is charging but if i plug it into the pro 3 it gets hot and starts to produce smoke. I have tried with other type c cables and the port is burning them also. Now it looks like I need to replace my usb port. I will have a closer look at it to see if it can be cleaned but I'm not hopeful. I hope i can get original parts for it because i was sold an old phone by an AliExpress seller who claims it's new. I have started a thread on it. Hopefully I can spin it out to ask anyone with information about where to get genuine parts to help restore these old phones.

Hi guys, greetings!
I'm a new member here
Apparently, I had issue with fast charging problem. Basically what I did was changing cable and charger over and over again. I had to change my cable to which can hold up to 2.1A and a charger that has same output with stock charger which is 5V at 2A and 9V at 1.67A. I even bought enough cables just to see whether it is working or not, yet it doesn't fix my problem. I haven't changed my battery since this issue, I assume that this issue don't came in the battery rather it is from cable or charger. So I changed my flexy charge, but still can't do such a thing.
I had to reset my phone and factory settings, and yet it doesn't fix my problem
For some reason I'm frustrated with normal charge because I had to wait my phone fully charge like around 6 hours. And it drain also around 6 hours on use continuosly.
But it's crazy that this phone can hold it reliable for 6 years without any issue. It still in better shape. My only issue that came up was camera focus, can't read my sim card, and fast charging issue. And a missing S Pen lol. The camera focus and sim card aren't a big issue, since I can use alternative phone. And I can wait longer for my camera to focus to one object.
My questions are :
1) Does the battery affect fast charging too? I have my stock battery here which is 3220 mAh. If it's true, then maybe I'm going to change my battery with a newer one.
2) Is it possible that the processor in it some tiny part (which it controls the fast charging) is broken and that's why fast charging is stopped working?
3) I need to upgrade my phone to a same note series, but it's hard to pick. I kinda like galaxy note 9 than a newer one. But I want you guys to give me opinion. I need a longer battery life and it said note 9 is a beast battery. And a compatible software updates in future.
4) Does the battery that comes up with custom battery capacity is safe? Like does it fast charging? (like a ZeroLemon 11000 mAh and some chinese product that doubles the capacity stock battery)
5) Does the OS affects too? (This is the reason I did factory settings so I can see if it's work or not)
Thank you guys!

Check your microUSB port and make sure the little flap in the port isn't bent and if it's dirty carefully clean the port. If you still have the original battery that came with your phone it will definitely need replaced with a new one. Lithium-ion battery degrade over time and have limited life span.

Yes! I did that before I changed my flexy charger. It didn't fix my problem. It seems like there's some tiny part in processor is broken for some reason (like I told in this thread) or maybe some part an IC in the motherboard who controls it also damaged. I really don't understand how fast charging works.
I came up with a solution that I bought two new stock batteries and a desktop charger. So if my phone's battery is run out, I could change with my alternative battery. But I'm still frustrated for how it can't fast charging again.
1- Try cleaning the charging port with izoprophilic alcohol and some small brush (let dray the port 1-2 hours after, DON'T START the phone)
2- Make sure you have a quality charging cable (the 5$ from gas station or chinese cheap crap there are no good)
3-Same thing like at point 2 but with charger
I have like 3-4 charging flex with ports for note 4 and all are faulty so maybe this if you buy from china or ebay and its not from broken phones original.
If you have all good quality charger and cable and good charging port maybe IC power managament on motherboard is faulty, not CPU.
You can fix it but depends where you live will be more expensive than buying a second hand motherboard from aliexpress, its like 30$ I buy recently for a N910C
Me I don't use fast charging becouse its get too hot and is a secondary device
I want to buy and me a bigger battery I found on batteryUpgrade a 6900mAh but I don't know the quality and its almost 50$

Yes, I also did that way before I change my flexy charger. I brushed it with izoprophilic alcohol on charging port.
I'm pretty sure all I have is a high quality charger and cable. I still have my stock charger. I think there's no issue with charger, I couldn't really tell, since I tried all possible different charger. But with the cable, yes, I tested it one by one, because the issue might come from cable.
I think after all I did what's possible, there's something wrong with my IC charging or processor. I couldn't understand it but, does it guarantee if I changed like I pull the broken IC and put it back a new one, will do the fast charging?
But really though, how does fast charging works? Is it include in processor by some tiny part transistor? or is it an independent IC in the motherboard?
100% is another chip on motherboard that do the charging
I have a similar problem with a samsung tab s t800 that charging very slow becouse of faulty IC power manageament
I'm opened my note 4 for many times until now and repairing it
I've been watching many board repairs I have some skills but no tools to repairs bords for now
Its not the CPU
I watch a similar board fix on note 9 and was a diferent chip on board that manage the charging
Go to a service if you want to repair, don't try to do something at home becouse you have hight chances to destroy much more the phone
Repairing you phone at a repair shop will be more than 30$ so better buy a "new" motherboard from aliexpress
