Abstract: A noise reduction headset setting method includes triggering a noise reduction headset to enter a communication mode when it is detected that the noise reduction headset is inserted into a preset headset jack and a communication setting instruction is received, where the preset headset jack includes a first line used by a first channel and a sending channel, a second line used by a second channel and a receiving channel, and a third line used by a microphone and communication triggering, receiving a headset setting request in the communication mode, where the headset setting request requests a firmware upgrade or noise reduction parameter setting for the noise reduction headset, and setting the noise reduction headset according to the headset setting request using the preset headset jack.

Abstract: A battery capacity tracking method and apparatus, and a device are provided. For two batteries connected in series, a first remaining capacity change value corresponding to a first battery when the first battery is switched between a fully charged state and a fully discharged state is obtained; a second remaining capacity change value corresponding to the second battery when the second battery is switched between a fully charged state and a fully discharged state is obtained; and after a remaining capacity change value corresponding to a battery when the battery is switched from one state to another state is obtained, a full charge capacity of the first battery is determined based on the first remaining capacity change value, the second remaining capacity change value, and a full charge capacity of the second battery.
