A refresh rate switching method and an electronic device are provided. In the method, the electronic device dynamically switches a corresponding screen refresh rate by determining whether a current display image is a high frame rate scenario or a standard frame rate scenario. In the high frame rate scenario, a relatively high screen refresh rate is used to support a high display frame rate. In this way, a user can obtain experience of the high display frame rate, and the display image is smooth without motion blur. In the standard frame rate scenario, a default low screen refresh rate is used to reduce power consumption of an entire system.

Refresh rate switching method and electronic device

Embodiments of this application provide methods, apparatuses, and terminal devices for managing communications services. In an implementation, a method comprises: identifying, by an input device of a terminal device, an operation performed on the terminal device for entering a service mode that prioritizes data services over voice services; sending, by a subscriber identification module (SIM) card of the terminal device, one or more instructions to a network server, wherein the one or more instructions instruct the network server to disable the voice services of the SIM card; and in response to identifying the operation, activating, by the SIM card, the service mode by disabling a function on the terminal device corresponding to the voice services.
