Rumor has it that games from companies like Zynga can heavily delete battery life on your phones and tablets, even when you haven't played them, because they have an always running background process of tracking-cookie like adware. I'm interested in trying out games like Angry Birds, Cut the Rope, Tiny Wings, and Fruit Ninja, but don't want them to eat away at my already much too short 4S battery.
Anyone have experience with those titles? Heard any stories about them screwing with battery life? Notice them screwing up your own phone?
