The video begins with a close-up of a person's hand holding a smartphone. The phone has a black screen and is being held in landscape orientation. The person then proceeds to plug a white charging cable into the bottom of the phone. The cable is inserted into the charging port located at the bottom of the phone. Once the cable is connected, the phone's screen lights up, displaying a colorful background with a message that reads "Use your fingerprint to unlock. Fast charging (65%)". The person's fingerprint is then used to unlock the phone, and the screen displays the message again, indicating that the phone is now charging.
