From brief experiments, I seem to use 5 MB for 10 minutes of playing – is that in line with what other players experience?
There’s a huge data impact when you first open the app after having not used it for a while, so playing like once a day will make it seem like it takes way more than playing a lot really does.
1 month of virtually continuous play, taking breaks here and there, ate about 265 MB of data (there’s 2 days left in my billing month). That’s just under 10 MB a day. It’ll also reduce your usage if you boot up the ap and check all relevant leaderboards whil connected to wifi, then resume regular play while on 4G.
