Either that, or Android devices will need significantly larger batteries to get comparable battery life to a iPhone.
samsung galaxy rubgy pro 1850 mAh (mine)
iphone 5 1440 mAh (wife)
with comparable use between the 2( texting, games, video watching, actual phone use), I get almost quadruple the life between charges as she does
her phone gets 8-10 hours on a charge, where I can get away with charging every other day almost (i can get 36 hours between charges np, sometimes 40)
now granted battery life is one of the few things this particular model does, but it doesn't take a crazy huge battery for android to out perform iOS
