Here’s a list of steps you can follow to try to troubleshoot the phone not charging:

1. Check the phone and the cable for any physical damage or debris on the charging port.
2. If there is damage or debris present, use a can of compressed air to clear it out.
3. Check that the cable is properly connected to the phone, and try a different cable or wall charger.
4. If the phone still will not charge, reset the phone back to its factory settings.
5. If the issue continues, contact the phone manufacturer for more support.
