Meet the new Smart Battery Case for iPhone 6s and iPhone 6. It is a battery extending case that adds up to 25 hours of talk time, allowing you to do more with your phone. The case also keeps your phone protected. Putting on the cases or taking it off is not that painful either.
You can charge your phone and battery case simultaneously. The battery case works with your Lightning accessories. It is available in two colors and costs $99.[where to get it]
