The battery life is incredible for me (~72h max) and don’t think I ever experienced any lag.
I think it is probably only a small number of people that have the battery issues and posted online since the ones with working phones won’t post about that. Could be a software issue (Network reconnecting? Battery not properly calibrated?). Anyway this should be fixable by RMA on the off chance that it does happen to you.
But isn’t the whole point to play a burned copy of the game?
This seems like scalping concert tickets to a concert that allows you to copy tickets in the printer.
