The're a many posts about charging problems here & on Sony Talk forum.
Since upgrading to 4.4.4 .108, I got charging problems.
My phone is 8 months old .
Slow charging or after a few minutes it charges or after a reboot.
I tried the trick of holding power & volume for 5 seconds. (shutdown)
Has anyone else experienced this too?
I did a fresh install .118, rooted it, TWRP flashed a Custom Rom.
My old cable, did not work well, because it didn't fit properly in the Usb connecter.
(I could move it a little / space)
Tried my former Xperia T Usb cable, this works sometimes.
If I use my wifes new Z1 Usb cable it works good.
Could it be hardware or software & Cable?
Could the usb port on the phone be damaged or dirty?

If you use your wifes Z1 USB cable and works just fine just try getting a new USB Cable
I orderd a new original cable, this fixed the problem

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)
Hi there,
I think im having a unusual problem with my Note 9. Whenever i try to connect usb C to usb C there will be no charging or connecting to other devices. If im connecting from usb C to normal usb it will charge the phone.
Things i did:
- factory reset
- clean port
- other cables same problem.
- other phone same cable it works as expected
- replaced the connector of my note 9 same problem
- after some days quick charging stops working and a full charge will take 6/7 hours. i have to reboot to get a full battery in 2 hours.
- connecting my note 9 to my zenscreen go usbc/usbc it will not detect (OTG) my zenscreen go
- Using a OTG checker app gives me all green V
I really hope someone has come across this problem and point me to a solution.
