Heal or revive injured/fainted Pokémon using potions and revives. Acquire items from PokeStops, defeating Raid Bosses, research tasks, gifts, or the in-game store. Remember to strategize with healing ...

Additionally, in Max Battles at three star difficulty or higher, if all your Dynamax Pokémon faint, they can aid those still in battle by ‘cheering’ them on and boosting their Max Meters.
