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.

Did you try turn off smart charge in battery > More battery settings > Smart charge ?

Question Solved! Mi 11 Ultra charging

Hello, i just bought a Chinese Mi 11 Ultra. It came with a 67W US charger + US to EU adapter (i live in EU). When i'm charging the phone it says "turbo charging", not "67W Max". I tried a 33W xiaomi turbo charger and it charges the phone at the same rate (at least that's what it says in the battery section).
Can anyone help me with that please ?

Hi infamas,
did you try another USB C cable ( it must be the orange one...)
--> Usb-cable
Good night

yes i tried two different 6A orange cables, same result

Hello, I have about 3 weeks since I received my Chinese cell phone with global ROM. It included a "67W" charger as a gift but the truth is, even though it comes with the original cable, I think it is not the corresponding charger. My wife's is also 30W and I feel that it gives more Loading capacity.
I bought a 66W car adapter, and I haven't had a chance to use it for more than 10 minutes, and I think it's the only one that gives 100% of what it offers. I don't know if a warning will appear that it is the maximum power
In the screenshots, guess which one is mine?

SOLVED! The cable was the problem. It turned out to be non original or a 6A cable for Huawei/Honor.
Now when i connect with the original 6A Xiaomi cable i get "67W MAX" charging appear on my screen and it is 2-3 times faster than turbo charging.
