Abstract: A chip package structure and a chip package method, the chip package structure including a die and a package substrate disposed around the die. A solder joint is disposed on a first surface of the die. Remaining surfaces of the die other than a second surface are wrapped by an injection molding material. At least one pair of opposite sides of the package substrate is embedded in the injection molding material. A contact area between the pair of opposite sides and the injection molding material accounts for more than half of a surface area of the pair of opposite sides. The second surface is a surface that is of the die and that is opposite to the first surface.

Abstract: An electronic device comprises a processor, a charging port, and memory that stores program code. When the program code is executed by the processor, the electronic device charges a battery of the electronic device using the charging port when a charger is connected to the charging port, stops charging in response to detecting that the charging port is abnormal, and displays a first window on a display interface of the electronic device in response to detecting that the charging port is abnormal. The first window comprises a first prompt information and a second prompt information. The first prompt information is used to prompt that liquid intake exists in the charging port, and the second prompt information is used to prompt a user to exclude a liquid intake situation of the charging port.

Abstract: A charging method and a related device are provided. A charge protection apparatus includes a micro control unit MCU, a current detection circuit, a gating circuit, and an I/O interface. The current detection circuit detects an external charging current flowing through a power cable. The current detection circuit transmits the external charging current to the MCU. The MCU transmits the external charging current to a user terminal by using the I/O interface, so that the user terminal calculates a current difference between the external charging current and an internal charging current detected by the user terminal, and determines, based on the current difference, whether to generate a circuit control command. The MCU receives the circuit control command sent by the user terminal, and controls, according to the circuit control command, the gating circuit to be in a closed state or an open state.
