Not charging anymore

My fairphone 5 is not charging anymore.
I changed battery, USB port nothing worked.
I event changed the loud speacker part if this could come from here for any reason.

Nothing worked.
As anyone already experienced this ?
How can i solve it ?

Bonus question ; if i buy a new phone i wont be able to cable both to transfert android data.
Is copying the file from phone to SD card, then SD card to new phone enough ??
I don’t want to lose precious conversation (for exemple)

Did you test your cable, your charger?
Did you double check that the connector is well connected?

I used 3 cables 2 power source and a portable battery.
I heard the cliping sound from the usb connector when i changed it the two time.

My FP5 recently stopped charging as well.
I had a spare battery so I backed it everything (mainly to the cloud but also used syncthing app for pictures).

The whole repair took a week and Cordon said the connector was displaced. I wanted to verify with them some details before posting here the whole thing but perhaps even this partial experience could be of some help.
