Niantic finally launched trainer battles on Pokémon Go late last year, giving you a way to take on friends or any other random players you come across. Now, the game developer has started rolling out an upgrade for the feature that'll have you swiping on the screen. The Charged Attack mechanic in trainer battles used to be all about tapping on icons as fast as you could. After installing the update, though, you'll have to swipe on the screen to collect as many icons as you could to power up your Pokémon's attack instead. It's more Fruit Ninja than Harry Potter: Wizards Unite, but it could amp up your enjoyment if you never quite liked furiously tapping on your phone.
