Hi,
Every time I try to charge my phone by cable, it powers off completely and doesn't proceed to charging. I've tried multiple cables with different charging power, I've removed dust from the charging station. If I charge it wirelessly it works, but it's painfully slow. What should I do? Should I change one of the parts of my phone?
Esta é uma boa pergunta?

@maximebequet this could possibly be an issue with the power management IC or other components on your main board. You will need some the schematic and board view (as well as some decent tools and the ability to test circuits etc.) of your main board to determine this.
It is also possible that the charging cable shortens out the charging board (sub board) Replace that first and see what happens. Here is the guide for the task Samsung Galaxy S21 Daughterboard Replacement . The cost for the board is not very high and it is readily available at many online places.

Oh alright! Big thanks. I've just ordered a new charging board. I will see if that fixes the issue. Thanks for the help. Will write here to tell you if it works.
So, here I am again. I've replaced the charging board, and the problem is persisting. Still getting the exact same bug where it powers off when charging. Now I actually don't know what to do anymore :(
@maximebequet the next thing to do is to replace the Flex cable that goes from the charging board to the main board. See if that works. After that we will have to "dig" into the main circuit board and see if there are any components that may have been shorted etc. Also, if you can get a USB ammeter to check how many amps your phone is pulling from the charger, it'll be helpful.
