If you pour liquid into your charging port, the first thing you should do is switch off your device and, if feasible, remove the battery. This will assist to keep the equipment in good working order. Then, gently shake or blow any surplus liquid out of the port. You can then attempt to blow away any residual liquid with a can of compressed air. Spray the air into the port while holding the can upside down, being careful not to harm any components. You may also gently scrape the interior of the port with a toothbrush or a tiny brush with soft bristles to remove any dirt.
