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)

Hello everyone.
I have a really big problem with my Xiaomi Mi3w (Cancro) and i haven’t find a solution in months.
I have an issue with the battery(?) or with the micro usb connector, sometimes i can’t charge my battery, no matter what or how, i can’t in any way.
When i connect the phone to the wall charger it doesnt charge or it even drains the battery, even if it’s off, it happened that some times when i connect the phone to the charger at 20+% battery after some hours it’s at 10%.
When the phone behaves like this and i try to connect it to the pc it can’t seem to hold the connection for more than 3-4 seconds, it continuosly connects and disconnects and it’s impossible even to open it in explorer. Obviously it’s impossible to charge even in this way.
At first i thought that it could only be a hardware problem (faulty connector/charger/cable etc)
but the last time i had this issue (today) i discovered that i can keep the connection between pc and the phone using fastboot. When i use fastboot the phone doesn’t disconnects continuosly so i can say that in 99% it’s not a connector/cable problem.
Could it be a kernel bug? I know that the kernel it’s active even when the phone is off but in charge, this could explain the charging problem even if it’s off.
Another thing that i discovered is that when the phone is on the connection to the pc gets more stable if i turn off debug mode ( can keep the usb connection on for more than 30 secs but i can’t seem to charge it anyway).
Things that i tried to solve the problem:
-Change the charger (1st charger is xiaomi’s orignal/ 2nd it’s a sony with output 5V/850 mah/ 3rd is a lg 4.8V/1A/ 4th is a generic tablet charger which came with my acer iconia with 5V/2A) none of these solved the problem.
-Change the cable (used 10 and more different cables, every cable was tested with my other devices and all were working well with my moto G and acer iconia)
-Fastboot install of both stable and developer rom
-Clean fastboot install of both roms (formatting both systems earlier with cwm)
-Install via cwm of ivan 4.4 aosp and cyano 12 (both of these uses the same leaked kernel right?)
-Cleaning connector with a neddle, soft cloth and some alcohol
I’m not sure about this other point but the phone seem to get in this not charging state when the battery gets below 30% and i keep it uncharged overnight.
So i thought that i could also be a problem related to the governor used by the phone when gets to a low battery profile and specifically when this governor tells the phone to get in deep sleep.
(this could perhaps explain the problem of both cyano and ivans roms random reboots and the workaround using partial_wake_lock)
I hope that someone can help me to solve this problem because my device is useless now
Thanks in advance to everyone
i have the same problem with my MI3W. Sometimes i can charge it while smartphone is power off.
I tried with another battery. I am waiting for a new usb connector flex to check too.
Do you find any solution?

I think i might be having the same problem. My phone started acting weird at the exact same condition. The charging connection kept going on and off. Felt like hardware issue at first. Charged my phone somehow to full charge and reset it. Looks good now but still skeptical.
Fingers crossed.

Hi i resolved the problem some time ago, cleaning the connector with a very tiny needle, i didn't go very far the first time that i cleaned it, probably it's only dirt, try cleaning it yourself and see if it resolves the problem
going fine

Tested for one month, ....never cleaned the connector though....
Never faced the problem again, though i have changed roms.:good::good:
Anyways, hope it never comes back again
Thanks Lace.....
Hi there,
As the title says, my Mi5 doesn't charge unless I turn off the phone. If I keep it turned off then it charges, If I turn it off, plug the charger and turn it on while charging then it's ok, the charging process continues. If I unplug the charger in the process then I have to turn it off again. Connecting to the PC via USB can also be done only by turning the phone off.
I tested it with 3 different cables and chargers which otherwise work on different phones.
I tested this on Xiaomi EU ROM and on Lineage OS as well.
I'm thinking this issue is software sided since I can charge it while it's turned off. Did anybody else encounter this issue? And ideas on how to solve this problem?
Thanks,
Frost
Hi,
i'm having the exact same problem.
the weird thing is that even in TWRP USB only works when it is connected during power up...
Which rom are you using ?
Maybe dirty flash causes this. Or there are some problems with the kernel. Try flashing stock miui.
have tried the lineage (20170718), and the latest MIUI versions (global and china, stable and develop). no change
This problem has just presented itself on my phone. Mi5 32GB. AFAIK I didnt change or do anything. Have since completely clean flashed including firmware and it still does it. Did anyone find a solution for this? Totally bizarre!!
Currently:
Mi5 32GB/3GB
Cosmic OS 3.1 Oreo 8.1
Firmware 7.9.22
Unofficial Gapps 01/06
Try a different kernel, for example Soda Kernel

I no longer have the Mi 5 and I don't remember if I fixed the problem or not, I think resetting to factory default MIUI might have solved the problem.
I had the same issue, and resolved it by deleting "Advanced Charging Constroller", a Magisk moduel.
Hope it helps if you are in the same situation.
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'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 everyone, just want to share my problem on side port charging. Once im charging on the side port it goes on and off. My first trouble shooting is possible the cord is faulty. But ive tried to plug it on the bottom port and smoothly working. I just tried to restart but still the problem occurs. And then i tried to shutdown the port and charge. Its charging continously on the side port but too slow. Then i tried to open and it works. But after i re-charge the problem appeared again. Can someone help me to figure out this problem. Im using tencent globlal 1908.65
