Embodiments of this application provide an antenna tuning method and apparatus, an electronic device, and a readable storage medium. The electronic device includes a first radio frequency link and a second radio frequency link. The first radio frequency link includes a component configured to detect an antenna parameter, and the second radio frequency link includes a tunable component. The method includes: obtaining first antenna parameter information of the first radio frequency link by using the component that is in the first radio frequency link and that is configured to detect an antenna parameter; and tuning, based on the first antenna parameter information by using the tunable component in the second radio frequency link, an antenna corresponding to the second radio frequency link. In embodiments of this application, an antenna corresponding to a radio frequency link that does not include an antenna parameter detection component can be tuned.
