Android O lets you block the activity of apps that are not in use to save your phone's battery. In this way, the software does not perform processes that are hidden to the user, but that continue to consume energy. Although the system controls newer apps on its own, you need to adjust the others manually in the settings.
The feature is also useful for restricting the operation of heavy apps, such as Facebook. Here's how to use the feature that prevents your phone from running on battery power with apps that are closed. The procedure is valid for smartphones that already run the latest system from Google, such as Galaxy S8 and S9, Moto Z and Moto Z2 Force, among others.
