Just like in the P20 Pro, the USB-C charging port is mounted to a large flex cable. This means if the charging port fails, you'll only have to replace the main cable—instead of a more expensive daughterboard, as in the Google Pixel 3 XL.

Another similarity to the P-Series: no 3.5 mm headphone jack. USB-C headphones are included along with a 3.5 mm adapter.

Yet, the Mate 20 and Mate 20 Lite both still have a headphone jack. Maybe Huawei isn't quite sure if USB-C alone is the future.

The other port, a SIM reader, is mounted to a small board, and planted near the coin-style vibration motor.
