Apple Smart Battery Case

Inside, a soft microfiber lining protects your iPhone. The silicone exterior feels good and fits comfortably in your hand. With the design featuring a soft elastomer hinge, you can easily slide your iPhone in and out of the case. When you charge your iPhone and the battery case, you get an extended talk time of up to 26 hours, can browse the internet with LTE for up to 22 hours, and enjoy longer audio and video playback. The Smart Battery Case displays an intelligent battery status on your iPhone's lock screen and in the notification center, so you always know how much power you have left.
