Abstract: An electronic device low-temperature protection method includes: obtaining, by an electronic device, an environmental temperature and a temperature of a battery of the electronic device; determining, by the electronic device based on the environmental temperature and the temperature of the battery, that the electronic device is in a low-temperature environment; and implementing, by the electronic device, low-temperature protection in response to the determined being in the low-temperature environment. According to the electronic device low-temperature protection method provided in this application, both the environmental temperature and the temperature of the battery are considered, and whether the electronic device is in a low-temperature state is detected based on the environmental temperature and the temperature of the battery.

Abstract: 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.
