Clean the USB port of your smartphone
If your phone refuses to charge then you need to make sure that the problem is not with the cable. To check this, just connect the latter with another phone.

- Disconnect your mobile phone from the charger and gently shake it while placing the USB port (Android) or Lightning connector (iPhone) downwards.
- Wipe it with a dry, lint-free cloth to avoid leaving residue in the USB port.

- You can also do this step manually by using a fan that you point in the direction of your device’s USB port.
