As someone who has had multiple iPhones and Androids, with MY PERSONAL usage patterns, a normal Android (no battery saving apps) would never come CLose to my iPhone battery. Of course i have a maxx . If you're still able to swap out, you may want to get a phone with a removable battery. Honestly no Droid (besides the maxx) should have a non removable battery
