Apple Smart Battery Case

Inside, a soft microfiber lining protects your iPhone. The silicone exterior feels good and is comfortable to hold. With the design featuring a soft elastomer hinge, you can easily slide your iPhone in and out of the case. The Smart Battery Case is compatible with Qi-certified chargers. You can charge both your iPhone and the battery case simultaneously. Together, you get an extended talk time of up to 33 hours, can surf the internet for up to 21 hours, and enjoy even longer audio and video playback. The Smart Battery Case provides an intelligent battery status display on your iPhone's lock screen and in the notification center, so you always know how much power you have left.
