Android phone won't charge

Symptoms

• No charging icon appears when plugged in
• Phone only charges in certain cable positions
• Charging starts and stops repeatedly
• Screen stays black even after time on the charger

Likely causes

• CommonDebris or lint packed in the USB-C portPocket lint builds up and blocks the connector pins from making contact.
• CommonDamaged or worn charging cableFrayed or bent cables are the single most common cause of charging failure.
• PossibleFaulty wall adapter or USB portA dead outlet, weak USB port, or failed adapter won't deliver power.
• PossibleSoftware glitch preventing charge recognitionA restart often clears a stuck charging state.
• Less commonInternal charging port or battery hardware failurePhysical damage or liquid exposure can damage the port or battery connector.

What to do

1. Inspect the charging port with a flashlight for lint, dust, or debris.
2. Gently clean the port with a dry anti-static brush or a wooden toothpick; never use metal objects or liquids.
3. Try a different cable and a different wall adapter or USB port.
4. Plug into a wall outlet directly rather than a computer USB port, which charges more slowly or not at all when the phone is off.
5. Restart the phone by holding the power button, or force restart per your model's method if it's unresponsive.
6. Watch for the charging icon within a minute or two of plugging in.
7. If nothing works, try a known-good cable and adapter from another device to isolate whether the phone or accessories are at fault.
8. If the phone still won't charge with confirmed-good accessories, the port or battery likely needs professional service.

Tools and parts

• Flashlight
• Anti-static brush or wooden toothpick
