Amazon offers Apple’s iPhone 7 Smart Battery Case in Black or White for just $84.99 with free shipping, which is a savings of $15 and a match of the lowest price we’ve ever tracked. Once you get past its infamous ‘hump,’ there’s a lot to like about this battery case. It features Lightning input instead of Micro-USB like most third party options on Amazon, deep iOS integration, and some impressive power management technology.
Pass-through power allows you to charge your iPhone 7 and the case at the same time using a single Lightning cable. The 2365mAh Apple Smart Battery case increases your talk time (up to 26 hours), internet use (up to 22 hours), and video playback (up to 24 hours).
