Realize a couple of different factors will play into your problem. Keep in mind that the iPhone 4 and the 4s we're both 3G devices. So that alone wasn't running their battery much. If you're in it LTE neighborhood, then that's going to be a factor that uses up more power. Also, Iphones don't multitask...androids do. What I mean by that is when you're just using your iPhone app for whatever purpose, the app is done once you click off of it (iPhone whatever app wants to send you push notifications). Whereas if do you the same thing with the Android, its pulling multiple information from multiple sources... Which also uses battery life a bit. Its basically all about just being smart with your phone, by taking the time to learn it. I only have what I need to have on my phone, and I easily last longer than 15 hours between internet surfing, texting, video watching on YouTube, music at the gym which is about one and a half to two hours continuously and game play.
