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: An application control method and an electronic device are provided. The method includes: The electronic device displays a first user interface of a first application, where the first user interface has N graphical controls; and the electronic device updates the first user interface if a temperature of the electronic device is less than or equal to a first preset temperature, so that an updated first user interface has less than N graphical controls, where N is a natural number greater than 1. In this manner, when the electronic device has a relatively low temperature, a user may be restricted from using some functions of an application.
