We recommend that you always close open applications so that they do not continue to run in the background and avoid unnecessary battery consumption.
To do this, click on the square icon that you will find at the bottom right that gives direct access to Applications:
Move between the apps that are open.
To close an app, slide it to the top edge or to the right (depending on the model).
Click on "Delete all" or the trash can icon, depending on the model, to close all apps.
