How much data and battery life will I use while playing Pokémon Go?
You will use a lot of data, so if you don’t have an unlimited data plan for your phone, be careful. Think about it: Pokémon Go
requires your phone to be constantly checking and transmitting your
location via GPS, which is a data-heavy endeavor. And the very nature of
the game — namely, the impetus to get outdoors and keep moving — means
that more often than not, you’ll be using a cellular connection rather
than a wifi connection.
Additionally, the game’s constant use of your camera will
quickly drain your battery. You can try the age-old trick of decreasing
the brightness of your screen to save some juice, but your best option
is to have some kind of external and preferably portable power source,
like a backup battery pack.
