Try turning it off and see how great your battery is? Why would you have double tap to wake on if you were sleeping for 5hours. Double tap to wake is just useless to me, I am not at an age to drive yet(age 14), I obviously don't need to double tap if it is in my pocket if I can single tap the lock button. It might be useful to a cook and someone who drives but probably only if you have a dock. My battery has performed pretty well after update, I listen to music 2hours while riding bus to and from school, might play some games too, keep it in my pocket check it at my locker etc and when I get home it is usually still +90% depending if I played a lot of games.
