Understanding Galaxy S25 Edge charging
The Samsung Galaxy S25 Edge reaches 25W only when the charger, the cable and the phone agree on the same fast-charging standard. An old USB-A cube or a cheap gas-station charger falls back to about 5W, which can make a full charge take three hours or more.
Samsung phones charge in fixed steps: about 15W on a regular USB-C PD charger, 25W on a PPS charger.
Do you need a special cable?
Any good USB-C to USB-C cable rated 3 A (60W) handles full speed.Check yours with our USB-C cable checker.
Test your charging
Compare other chargers with the charger compatibility checker. If charging keeps disconnecting, run the full phone diagnostic to test the charging port, and remove lint from the port with a wooden toothpick.
