Play this online game named PocketLock - Battery Saver for Pokemon GO.Pokemon GO, games, and video players stop running when the screen is turned off.
Poke Lock handles that gracefully - it turns screen Off when phone is in pocket, but keeps Pokemon GO alive and hatching eggs / detecting pokemons.
Same applies for Netflix, HBO GO or other video apps - you can listen to your favorite playlist while phone's screen is Off and safely locked in your pocket.
