Apple has designed and released its own external battery case for the iPhone 6 and iPhone 6s. The accessory is formed by soft-touch silicone.
The battery itself is concentrated in an obvious rectangle on the back surface. The case wraps around the phone entirely and plugs into the Lightning port on the bottom to deliver its charge. Apple says the external power cell is good for 18 hours of LTE web surfing.
Both the phone and the case can be charged at the same time. The case works with the iPhone to deliver intelligent battery stats to the notification center.
The case, sold in white or gray, is available online for $99.
