This source consistently shows 3-4 android phones trouncing the iPhone 5s in battery life in all tests. You were saying something about iphones having better battery life than androids? That’s a pretty bold statement to make.
One of the biggest things I can think of that shows the battery life difference between the iPhone and Android phones is people’s reaction to phones with non-removable batteries. Most people with an iPhone seem to not really care much about not being able to swap the battery because it is hardly ever and issue they have to think about and that is with a MUCH smaller battery than the average Android phone. People that buy Android phones are often upset about small batteries(like the 2,300mAh battery of the Nexus 5) and non-removable batteries because it is really an issue. Any Android phone besides the G2 and Droid Maxx need either a battery swap or charge at some point during the day to get through a day of moderate usage.
Facts are facts and the data shows that per mAh the iPhone gets much better battery life. If Apple made an iPhone with a 3,000mAh battery it would probably last DAYS of heavy use.
iPhones get a little bit better battery life on much smaller batteries. Take something like the Galaxy S4 for example. It can get about 9 hours with about 2.5 hours of screen on time with a 2,600mAh battery. The iPhone 5S can out last that on it’s 1,570mAh battery. That is 60% the size.
