Mi MIX 2S Qi Charger

I have a problem with charging qi in MI MIX2s the phone is charging up to 50-60% and suddenly the charger stops flashing diode that charging was interrupted after re-loading, it charges to 90-100%
if someone has such a problem and can be guilty
try a different charger you might have a problematic charger, have tested non brand and xiaomi wireless both charge the phone just fine(slow 5w ...maybe due to custom rom? ...still charging)
I was experiencing problems too (even with the original dark blue xioami charger).
In my case, seems to be software issue. The phone charges way faster with the phone turned off. Also when on, sometimes it says that is charging slow being in the same position that charges ok with the phon turned off.
Also on a thread of the last update (still beta), someone said that the wireless charger worked better, so im looking forward to test it.

Mi Room v9.2.29 Charging Issue

Hello Team,
I just installed Mi Room v9.2.29 for my Xiaomi Mi5 device. The performance and features of the MIUI 10 are really excellent. But I have a problem; the device stops charging approximately 15 minutes after plug device into the charge. I thought the problem was in the wall plug, but I tried to charge the device in different plugs and the same issue still continues. I tried to charge with my second charging cable but same issue. Is this a general issue for Xiaomi Mi5 devices?
Thanks for an advice!
Best Regards
i did noticed it sometimes. but maybe mine could be port loose connection. but it isnt occuring too often. it's sometimes..
but i m note sure if its miroom issue.
clean the usb port with something because sound like you have debris inside the port
I have not charging issue when using this time but Im facing fast battery drain when play games. It's drain very fast... I did try miui 11 eu 9.10.10 and Mi room but the results are same.

USB and charging problem / software issue ?

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).

Xiaomi Mi 9t Pro - problem with fast charging

Dear all,
I have problem with my Xiaomi Mi 9t Pro, it stopped fast charging. My phone is on Miui 11, Android 10.
Some day i've noticed that i've got only 1 "thunder" icon during charging. Charging from 0% to 100% takes about 7 hours now.
What i've done so far:
- tested on charger which was included in the box - no fast charging
- tested on Xiaomi Power Bank with fast charging - no fast charging
- tested 4 diffrent cables - no fast charging
- tested on turned off phone - no fast charging
- i've downloaded last update package and install it once again - no fast charging
- i've tested charging speed on ampere - maximum is 800mah
I've found some topics on various forums but there was no solution for this problem.
Any ideas friends?
Worst case scenario it is damaged charging port. Try to clean it using thin piece of wire or needle, it's easy to clog it up so the plug doesn't go all the way into the port.
I would take the phone to a service center. Even without fast charging is not possible that it takes 7 hours to get a full charge. It seems that the charging port is defective.
Good luck.

What kernel do you use with miui? Stock or custom? Some kernels don't support charging via 5A cables. Use 3A instead. Also, clean your usb port with a toothpick and see if you can remove any dust from the pins.
