If you ever find yourself wanting to conserve Revives or were planning to Power Up a Pokemon, you should know that spending that Stardust and Candy will restore the Pokemon from a fainted state!
Unfortunately, only 1 HP is restored, but it's enough to allow you to use Potions alone, instead of a Revive and Potions.
So before you go on a Power Up spree, consider hitting a Gym - you'll get to use those Power Ups as Revives!
