I think it could on wifi. Pure standby? I'm not too surprised by that stat. I played quite a bit of temple run and left my iPhone at home the whole day, and by the time I was ready to go to bed it still had 75% battery life. I imagine if I didn't touch it AT ALL, it would've been well above 85%.I highly doubt the phone lasted 8 days on standby.
However, I do think that the stat wasn't reset because a full charge wasn't performed.
