There are different locations you can visit in Harry Potter: Hogwarts Mystery where you can tap the screen on areas that will give you free bonus energy. The reward can come from attending your lessons during each chapter, or by completing other tasks from characters you interact with during the story. Sometimes after earning a star, 1-2 points are added to your energy bar automatically when XP is added to your level meter. If you find yourself losing more and more energy, choosing this as a reward will give you a small boost to help you keep going, although most times this is not the best deal. You can choose to gain skill points, gems, coins, or energy every time you finish a large task. When finishing some tasks, you have a choice for the type of reward you receive. Throughout the game, you will earn energy for completing lesson tasks and activities you come across in Hogwarts School of Witchcraft and Wizardry. If you have enough patience however, you can slowly earn your energy back to continue playing. This can take a long time in most cases, which may cause some to purchase additional energy in-game using real money instead. That means it can take over an hour to completely refill your energy bar without spending any money if your energy bar runs out. The rate your energy bar recharges is 1 Point gained every 4 minutes. This is the most basic way to earn energy for your game when you run out of it. By simply shutting down the game or letting it run in the background, your energy bar will slowly refill as time passes.
