If you run an android device, or any other computer that doesn't allow the user to do basic things like close apps. You should make use of the battery optimization settings.

On android every app that you don't want real time updates from should be set to restricted battery mode, and background data to off.

The only time you need background data is for real time updates or background play in apps like YouTube or Spotify.

This feature will almost certainly get removed in the future if history is any indication, so enjoy having decent battery life and better networking performance while it lasts.
