It does drain the battery a whole lot, a saw mine drop from 100 to 70% in about 40 minutes of play, before I turned flight mode on. The day after, it dropped from 100 to around 66% in about 1 hour or 1 hour 10 minutes or so, with flight mode on. To be fair though, I have barely used the handheld mode since I bought mine so I don't have very expansive data to compare against other titles or features, so I don't know what is considered normal.
