One of the biggest issue with playing Pokemon Go is that it eats up your phone's battery fast. One solution is to get a powerbank or battery case. But if you want to save power and up your game, you'll need the Pokemon Go Plus. It connects to your smartphone to alert you of events in the game. Your smartphone can be on standby while you roam around looking for Pokemon. There's no need to be looking down on your phone all the time. It blinks and vibrates when you're in range of a Pokestop or when there's a Pokemon appearance. You can even press a button to throw a Pokeball or search a Pokestop.
