Hi, thanks for the inquiry. The settings that you've set on the DJI GO 4 app should remain even after changing battery including the AFS setting. However, if the settings would change into a default mode, you may consider deleting and re-install the application. Please ensure that the important files are saved and flight records were synced prior to delete the application. Please keep us posted on the latest progress for further assistance. Thank you for continued support.
