When an iPhone 8 no longer charges, it can be the fault of many things. Typically it is the fault of the charging port, but when this is replaced and issues still exist then it may be time to look at the board.

If all the “external” parts have been replaced and tested (charging port/battery) then the fault can be related to what used to be called the Tristar, which has now been updated and renamed to the Hydra IC 1612A1 (U6300)
