Apple Smart Battery Case
It’s not the first battery case made for iPhone, but the Apple Smart Battery Case is the first designed by Apple itself. The case boasts a soft microfiber lining inside that softly cradles your device, a soft-touch finish on the exterior for added grip, and easy installation thanks to its soft elastomer hinge design. Its 1,877 mAh battery bulges out slightly, albeit not unattractively, and tacks on a fair amount of longevity, extending talk time to 25 hours or LTE internet use to 18. Most notably, the case supports Lightning accessories, charging using the same cable or dock as your unenclosed device would, and it displays its battery status on the lock screen as well as in Notification Center so you know exactly how much battery you’re dealing with at any given time.
