CoBattery iPhone case replaces conventional charging with swappable batteries

The main problem with iPhones and other smartphones continues to be how quickly their battery power gets drained after each full charge.

CoBattery is an iPhone case that addresses the problem by replacing conventional charging with swappable batteries. The light case comes with two batteries and a charging dock. One battery stays in the case, keeping the iPhone charged, while the other battery stays in the charging dock. When users come home after several hours away, they just need to swap the used battery with the one in the dock, providing them with a fully charged smartphone in seconds. Each CoBattery will ship in December with a case, two batteries and a charging dock at $75. Its maker is hoping to raise $60,000 by June 4.

The benefits of swappable batteries continue to be debated. Samsung left them behind in its latest phones while LG embraced them. There are already many iPhone charging cases, including the Charge Case. But CoBattery should be competitive thanks to its swappable battery concept. Each of its batteries offers 2.5 times more battery life than a regular iPhone, according to its Kickstarter campaign. Negatives include the lack of iPhone 5c and 6+ support, but CoBattery’s maker intends to support more iPhone models in the future, in addition to Android and possibly other operating systems.
