Uses battery when phone off

After downloading this game app I started noticing that my phone battery was going down a lot even when the game was off and my phone was off. I didnt mind too as much as long as I could recharge often during the day. Every night I make sure my phone is charged 100%. Since I loaded this game the next am my phone battery would be at 80% or so... But last night I had no charge at all in the am. I Deleted gem match from my phone and I have had no further unexplained drain on my phone battery. Cant say for sure this game was the culprit but game is gone and so is the battery drain.
