I'm thinking of getting the iPhone 5S. My only reservation is battery life. My last iPhone was the 4, and I found the battery life to be quite good. I could get through a full day with moderate to heavy use. Since then I've had a few android phones, only the S4 has had a good battery life, however it didn't really matter too much as I could carry a spare battery. So if I go for the 5S I need to know that the battery life is decent enough. I'd be using it for music / podcasts, video watching and tethering.
