> battery drained in ~6 hours So, parity with Android then? (I kid, I kid....kinda.)
My Galaxy Note 2 still has a battery life of about a week, still running on the original battery. I just need to remember to enable Wifi only on when needed, or it'll drain the battery in two days.
Of course, if you want a week on the battery, you must have data off, both wifi and mobile.
