摘要:
A motor vibration control method and an electronic device can implement vibration of a motor when a loading capability of a battery is low. A battery status is obtained when a first motor vibration waveform vibration request is received. The battery status includes a battery temperature, a battery temperature and a battery level, or a battery power supply capability. A motor vibration parameter is switched if the battery status meets a preset condition, where the preset condition is that the battery power supply capability is lower than a first threshold, the battery temperature is lower than a second threshold, or the battery temperature and the battery level are lower than a third threshold array. The motor vibration parameter includes a motor vibration waveform or a motor vibration input voltage. The motor is driven to vibrate based on a switched motor vibration parameter.
