hi, useful pokémon go tip again: to reduce battery and data usage, download maps offline on the google maps app. pokémon go uses the google maps api to load map data, which means that if you download the offline maps of areas you’re commonly at in google maps, pokémon go doesn’t have to to constantly refresh when you load up the game again or reach that area. you’ll instantly be able to tell by how fast pokéstops load the information

in the google maps app:

settings > offline areas > add icon > swipe around to download the map of whatever area(s) you choose
