Hi all,
I've noticed today out of nowhere, that my Galaxy Note keeps turning it's screen on due to being connected to a charger, when it hasn't. I've tried turning the phone off since it was seriously draining my battery, but it turns itself on and goes to the battery meter and then restarts again. The charging symbol appears when using the phone on and off, and I was just wondering what I could do to fix this?
I've tried flashing a new ROM incase but the problem is still there :/
Thanks in advance!
Try cleaning the contacts on your usb port.
Also your usb port could be damaged.
I have also a similar issue on my n7000 I replaced the port and its fine now Samsung ports from factory are crap

It also happened to me. I had to open up the Note and clean up the usb port to get rid of the problem.
Phone Charging when Not Plugged In - The Definitive Answer
Samsung Galaxy Note
I've had same problem as reported by many others with phone displaying charge icon when not plugged in. I've tried all the recommended solutions. Here's what I've found:
1. Not related to JellyBean update (it happened just after I updated but turns out to be coincidence)
2. Factory reset or flashing doesn't help (it's a hardware problem)
3. Clean out the USB port (there's all kinds of fluff, dirt, lost keys, foreign coins etc in there!) - don't use soapy water for this...
4. Bend the pins (gently) so that they are located in the centre of the port.
In my case it's the charging cradle I was using that was damaging the port. I'm using a flip-case on my phone which means the phone doesn't fit in the cradle properly and I was having to force it to sit on the connector. The pins had become bent and were shorting out against the edge of the port.
Replacing the port is painless, if you have any mechanical aptitude. Numerous youtube videos show how to change it.
Takes about 15 minutes. Just make sure you get the correct port. If you get the wrong one, you're signal will degrade
considerably
I had the same problem and I have managed to solve the problem by replacing the usb port. I bought the usb port from ebay but you must open up your note first to see which revision of usb port board you have inside the phone. I think it makes a difference so the revision number has to match with the old port.
Cleaning the port and straightening the pins helped for a few months but then the problem came back again. changing the old port for a new one solved the problem. I think their usb ports in galaxy phones are crap.
It's happen few days ago randomly everything works up to then. I can not charge my phone by just plugging my charger. I have to first switch off my phone only after that it responds to charger. Anyone has this issue, any tips? I have the newest software.

try different cables and plugs!
Tired different charger different cables everything different I different combinations. It doesn't work. I am guessing I more software problem what you guys think ?
I get a similar issue since a month or two: with Xiaomi.eu weeklies, if I plug in charger before switching off the phone, it will get in a sort of bootloop state showing battery then mi logo on a loop. Charging is fine while phone is switched on, though.

I use to unplug the charger before switching off the phone and then plug it back.
One thing I noticed was the USB C collects a lot of dirt in it. Every couple of weeks, I use a pin to scrape the dirt out.
As it is quite a large opening, it collects dust and lint etc, then plugging in the charge cable compresses it.
Give it a go!
I had the same issue, I solved it by changing from Xiaomi EU ROM to LOS.

Hello,
I have problem with charging. The phone is charging very slowly or not at all. Sometimes I can pull out and plug in and then it starts to load (but slowly). I checked other chargers and cables. I wiped all and installed new roms and nothing changed. Yesterday I saw that phone is charging in TWRP (but not always). What could be the reason? Battery, usb port?
Thanks.
Turn it off and try to clean the USB port. Most of the times it's not damaged, just dirty as hell.
Use tootpicks or q-tips, blow it, whatever. Just try to get it clean.
I managed to buy a new bottom pcb with usb port on ebay for less than £10 when mine burnt out. Does the port smell of burning?
Very easy to change if this is your problem

The port doesn't smell of burning. I will order this usb port, maybe it will help. Thank you for help.

Today I changed usb port and unfortunately I have still problem with charging. I will try to change battery
How long are you using your phone?
If it's more than a year and a half~, i would recommend you to buy a new battery.
A lot of people having battery related issues in the last few months including myself and for me replacing the battery did the trick.

Before I changed the battery the phone stopped responding to the charger, also it wasn't visible in the computer, only in fastboot, I changed the battery but unfortunately i dont solve the problem
Hi! This just happened to me as well after changing the battery to a new one (Nohon). It only charges in Fastboot or Recovery mode. Even after factory reset and rom reinstalled. Anyone found a solution for this?
Edit: it does charge in normal mode but on slow chargers, no qc3...
I had the same problem, I'm suspecting something in Lineage 15 or some new firmware was causing it.
Unfortunately after i roll back it did not solve the issue.
I have replaced battery but it does not solve the problem, QC adapters just do not work.
The odd thing is that a low quality cable on QC adapters or non QC adapters will have no problem.
And somehow trying to block off the data pin does not work as well.
I've rolled back to Lineage 14 but it sort of "fake" charge, percentage goes up really fast but in reality it barely charged.
EDIT: seems like some of the oreo firmware was causing it, i have downgraded back to 8.4.19 with lineage 14.1
Hi guys
I have this problem a few days , plug charger and very slow charging , sometimes stop charging ! Reset factory not changing (org miui my rom and 9.6.2 version)
I can downgrade to witch rom of android 7 without break of antirollback ?
Hello
I've got my Mi 9T Pro since one month.
Since one week, I can't enable MTP USB mode while connecting my phone on the PC.
The phone is charging, but no transfer mode available in the notification panel, tried developer mode, USB debogging, tried multiples cables, same problem. I can't transfer files by cable.
Also, charging is quite erratic, If I move the phone, charging can connect/disconnect.
At first I thought it was hardware issue, a problem on the USB-C connector. This disapoints me because I take care of my phones and I never had a problem like this.
But what just happened make me doubt. My phone was charging normally (it was around 50%) then stopped charging. Tried to plug/unplug, changing the cable, same problem, no charging.
I thought the USB-C connector was dead and that I could never charge the phone again.
But I tried to restart the phone and... it works. Still no MTP mode, but charging is working, while 10 minutes ago it was not working at all.
Do you think it could be a software issue ? Or battery issue ? Does anyone had the same problem ?
Thanks.
Yes
Did it solve ? And if yes , how did you managed to fix it ?
Because i m facing same problem as yours? Pls help me
Same. Weird issue. I guess the cable has become faulty. Or there's lint collected inside the charging port.
Have you fixed this issue? I have the exact same issue you described, I own a Mi 9T, installed Havoc OS

It is clearly USB-C issue (hardware).
That's mainly caused by instable current ,bad powerbanks, Powerful/weak chargers (not the original one) , or damaged/low quality cables, and also use/gaming while charging (the heat causes damage).
Use High quality cable , Original Adapter , you will never have this problem.
bottomline , you need to get your USB-C cleaned or fixed (in case of damage).
Hi,
I've been using my Redmi K20 Pro since November and I encountered a problem where my phone won't charge. I tried my backup charger and usb-c cable but it still didn't work. Once I restarted the phone it began charging again. Based on my testing once I unplug the charger I need to restart again to see the lightning icon charging indicator. I also noticed that the charging speed is very slow unlike how it used to. I am using xiaomi eu and I updated to the latest version thru the update app but still having the same result. Has anyone encountered this or have an idea on how to fix it? I see lots of similar issues with xiaomi phones but of different model on google but I can't find anything useful.
Thank you

Sounds like there's and issue with charging port and daughter board, if you've done a reinstall. Does the same thing happen when charging from a laptop or pc?

Ah okay, that's really strange, I was thinking it might be the port but if it works fine on USB then maybe not, and you've tried a completely different plug and cable aswell?
Do you use any battery charge limit apps?
If you are like me flashaholic, then sometimes with dirty flashing rom gets messed. Try flashing stock (fastboot rom) miui to teset everything to stock and then see if it charges normally. If not there could be hardware issue
With regards to the replies above..
I've only flashed once to Xiaomi EU. I've also tried a different usb-c cable
I notice that when I plug my phone to my laptop, it keeps getting disconnected and reconnected for any small movements of the cable
Sometimes I get fast charging when I perform a restart so it starts to charge
I don't use any battery apps or any cleaner apps

Sounds like the charging port has an issue, the fact if it is connecting disconnecting from movement of cable points to it I reckon
Hello,
Have you solved your problem? I have the same insue and I can't solve it, the last option was to flash the last oficial global rom (fastboot methdo), but it didn't solve it ...
Thank you.

So, I have this issue on my another phone poco f1 what I did was clean the charging port with some stick and cotton. Basically its a charging port issue, you have to clean the port or take a service to clean port completely or change port this issue will be solved
Mi 9T (Global) have the same issue, i check with USB Tester...
every restart the charging system is reset.
Before restart: 9-10W
After restart: 16-17W
Same adapter & Same cable & same time
Some times the phone not charge at all
Restart solve this issue
When i connect the phone to computer it's not work
Restart the phone when his connected to the computer solve the issue
Xiaomi fix you hardware & software !!!!
Hello
I have the same issue with my two phones MI 9 T PRO, never used USB C before, even 3.5mm jack, i have the error message on the notification and i cannot remove it: "Can't play audio through adapter. Use digital earphones or earphones with 3.5mm plug". when i plug my charger into my phone the fast charge is displayed but it won't charge, The only way to charge my phone is to reboot it and it's charge like there is no problem! but the error message is still on notification but charge with fast charge! I bought my phones march 2020, and the issue appeared since sept - oct. I have the latest update MIUI 12.0.3.
I facing same problem on my mi9tpro with global miui12 what's going on guys how to fix the problem?
Hey guys, I think I have the answer!
Its all about the MIUI optimization, you just have to go into developer options, search for MIUI optimization, turn it off, restart, turn it on and restart again. Everything should go well after this! I hope all of you end with this headache!

Hello team!
I was facing the same problem on a Redmi 3S Pro, and decided to come by and let u guys know my handling of this.
My phone has quiet some years of usage right now and its a bit beaten, but still runs great.
Out of nowhere it decided to not charge anymore, and I noticed it would charge with device off or after a plugged restart.
It decided to work again after i entered fast boot (unplugged) and exited fastboot back into system then plugging.
Not entirely sure this fixed it, but looks like it.
Some notes:
I was trying a couple things like trying to enter safe mode and combinations of plugged/unplugged restarts
I did not factory reset
I did not let it end the fastboot loading (force rebooted somewhere in the middle of loading fastboot)
To fastboot, power off the device, then press power button and down volume
If u dont know what u doing, DO NOT go sticking metals into your usb port to clean it, cause if it charges when off, this is NOT dirt problem. Be advised..
I was able to reproduce the issue (sadly) after playing with normal reboot/fastboot then reboot , but then i tried reproducing the fix:
Unplug and turn off device
Turn on to fastboot (down volume + power)
Now, first time, after entered fastboot screen, i rebooted and it did not work, then i tried again but i had to let it run a bit longer on fastboot screen then reboot for it to work
I know the fastboot performs some system checks while loading, but i don't have much time to keep digging this, maybe another day i'll come back with more info.
I'm guessing its system issue, not hardware (at least in my case).
But now, charging is working even after normal reboots for me, so i think i'm onto something =]
Hope this can be useful to someone.
Happy hacking!
Cheers
Hello everyone , I had the same issue and fixed it .
My solution was to change the usb-c port (daughter board). everything works as its supposed now.
I looked everywhere for software issues , flashed many different roms to no avail.
There was only one rom that tipped me that there was a problem on usb c port though, ita pixel experience rom, it showed a persistent notification that there was something plugged in the usbc when there was nothing there.
once I replaced my port (cost only 14$ for original with fast charging IC) ,and upon inspection of my replaced board under microscope , the last pin on the left in the usb C port was bent in a way that was impossible to see with a naked eye, now I bought a usb c port and soldered it back to my original daughter board and I keep it as spare one.
Hope this will save you your battery and your time.
(if you keep using like this and have to restart everytime for a charge , it will eventually fail , better replace it when you have time , than your phone going off when you most need it)
