The Galaxy A54 5G has a 5,000 mAh battery and supports 25 W fast charging, and its charging complaints on Samsung's community pages come in two kinds: a phone that does not charge at all, and a phone stuck at normal speed when it used to fast charge. For a phone that will not charge, the order is cable, charger, port, and software. Try another cable and a Samsung charger, then look into the USB-C port with a flashlight for lint, which packs in with pocket use and stops the plug seating. For a phone that has lost its fast charging, owners report that a software update changed the behavior: after One UI 7 some A54 phones charged slowly until a fix.
The advice is to check that Fast charging is switched on under Settings, Battery, Charging settings, to use a charger that supports USB PD with PPS at about 25 W or more, and to clear the data of the USB Settings system app, a step that cured several owners. Using the phone while it charges also slows charging. Check the phone in Safe mode too: a charging app or a battery monitor can interfere with charging in rare cases. The A54 has no wireless charging, so a pad will not help, and if the cable charges another phone but not the A54, the A54's port or battery is the cause.
