So I'm thinking ahead to the iPhone 6. With my Samsung galaxy phones I've been able to carry around a spare battery to pop in if needed. When I had my iPhone 5S I bought a mophie juice portable battery charger which I used, and still use for my iPod touch. My question is apart form the convenience of not having a cable dangling from the charger is there any additional benefits to using the mophie battery case vs the portable battery charger. Is one better than the other?
