When a phone won’t fast charge, the cause is almost always one of a handful of things — most fixable without buying new hardware.

  1. Check the cable is rated for the wattage, not just any USB-C cable
  2. Confirm the wall charger (not just the cable) supports the phone’s fast-charge standard
  3. Try a different outlet — some power strips limit output
  4. Check for debris in the charging port blocking a full connection

If none of these resolve it, the fault is more likely in the device’s charging circuitry or battery health than in the charger itself — especially if the same charger works fine on a different device.

Quick check

Before replacing any hardware, test with a different cable and a different outlet — this isolates roughly 80% of charging complaints to a single faulty component.
