This works best on an old phone. Have the phone plugged in for this method. The screen must stay on for this to work.

Download a game that pays sats per minute, download any free auto clicker from the Play store, set the screen timeout to 2 minutes, open the auto clicker and set it to click every 1 minute, open the game thru ZBD wallet to make sure tracking is enabled, turn the screen bright down as far as it goes, start the auto clicker, and put the phone where it will not be disturbed.

ZBD will count just having the app open as time on the app and pay sats on full passive as long as the auto clicker is running.
