She is the whiniest 15 yr old and is doing my head in about this because she apparently can't live her life if she doesn't have a working phone. I have sent her out to the car to put her phone onto the wirelesss charger, but that's pretty slow so she won't get a full charge in a reasonable time, especially as she is talking to her friend while charging. What can I do to get the bit of grit out of the charging port?
