For me, ‘fast’ charging the FP5 with an original Samsung 25W USB-C (PDO/PPS) charger results in max 22W charging speed as shown in the below graph (made using HomeAssistant). The dips in charging speed at 5:28 and 5:39 are when I briefly used the phone.
At 5:41PM I switched back to ‘slow’ charging, which apparently is ~4W.
