Quick takeaways
- Test the power source, charger and cable before assuming the phone itself is faulty.
- Do not insert metal objects into a charging port or force a connector that does not fit normally.
- Moisture warnings should be respected rather than bypassed.
- Intermittent charging can come from the port, battery, cable, charger or internal charging circuit.
Start with the easiest external checks
Try a known-good wall socket, compatible charger and cable. If another compatible device charges normally with the same accessories, you have removed some of the easiest possible causes.
Inspect the cable ends and charger for obvious damage, overheating, looseness or bent contacts. Stop using accessories that are physically damaged or behaving abnormally.
