The case features a dedicated camera button that launches the Camera app whether the iPhone is locked or unlocked. A quick press of the button takes a photo, and a longer press captures QuickTake video. It works for selfies too. The Smart Battery Case is also compatible with Qi-certified chargers. You can charge your iPhone and battery case simultaneously.

With the Smart Battery Case on, the intelligent battery status is displayed on the iPhone Lock screen and in Notification Center, so you know exactly how much charge you have left. The case can be charged even faster with USB-PD-compatible chargers. It also supports Lightning accessories, such as the EarPods with Lightning Connector (included with your iPhone) or the Lightning Digital AV adapter (sold separately).
