I just want to advice anyone who plans on playing this to get a spare battery or two, maybe a power bank to have on hand. I have a Samsung Galaxy s5 and I am able to play the game about 2 hours total or straight before needed to change it. I have a lot of apps going and text a lot so I am sure it will last longer for others. Keep in mind the more you stop and start up the game, the quicker your battery life goes down. It is using your camera after all so it is going to suck the life from any phone.
