A portable terminal 1 having a battery 11 obtains a congestion level indicating people-related congestion in a range including a point where a specific function of the portable terminal 1 is expected to be executed. Based on the congestion level, the portable terminal 1 performs a reduction process for reducing power consumption of the battery 11 before arriving at the above point, where the specific function is expected to be executed.

The present disclosure provides a charging method, a power supply device, and a terminal device. The method includes: transmitting, by the power supply device, clock signal to the terminal device via a first data line of the USB interface in a process of that the power supply device is coupled to the terminal device, wherein the clock signal is used for indicating a communication sequence between the power supply device and the terminal device; conducting, by the power supply device, a bidirectional communication with the terminal device via a second data line of the USB interface under control of the communication sequence, so as to determine to charge the terminal device in the quick charging mode; and adjusting, by the power supply device, a charging current of the power supply device to the charging current corresponding to the quick charging mode to charge the terminal device.

An inductive power transmission system electromagnetic field shielding apparatus includes an enclosure. The enclosure is configured to surround an electronic device and an inductive power transmitter that inductively transmits power to the electronic device. A communication window or high pass filter is formed in the enclosure. The communication window may include an arrangement of one or more conductive materials defining one or more apertures. The enclosure and the communication window block passage of magnetic flux generated by the inductive power transmitter. The communication window allows passage of communication transmissions associated with the electronic device.

A battery in a mobile phone cover for use with a mobile phone is used to charge a battery in the mobile phone according to a first battery parameter and a second battery parameter. If an application running on the mobile phone determines that a sensed parameter has fallen below a first battery parameter, then the application causes the battery of the mobile phone cover to charge the battery in the mobile phone until the sensed parameter reaches or exceeds the second battery parameter. The mobile phone cover also provides a notification on its display, for example, of an event (e.g., missed call, calendar alert, received message, etc.) when the event occurs on the mobile phone.

The present disclosure provides a power adapter and a terminal. The power adapter is coupled to a mobile terminal via a USB interface, and a data line of the USB interface is used for a bidirectional communication between the power adapter and the mobile terminal. The power adapter supports a normal charging mode and a quick charging mode, and a charging current of the quick charging mode is greater than a charging current of the normal charging mode. The method includes: communicating, by the power adapter, with the mobile terminal via the data line of the USB interface, so as to determine to charge the mobile terminal in the quick charging mode; and adjusting, by the power adapter, a charging current of the power adapter to be the charging current of the quick charging mode to charge the mobile terminal.
