S7 and 7Edge have better battery life I have heard, HOWEVER the whole family supports quick charging so it's pretty easy to cap off and/or charge up during the day if/when you have to. I have an iPhone 6 Plus AND a One Plus Three Android, plus I have had many others. I stopped playing the battery game a long time ago. I just have extra cords everywhere. I have several at home, one of each in my computer bag, and a quick charge hub (5 cords) in my office. My office mates even bring there phones in to my office to charge sometimes.
