Our Story

“Fat Battery started two years ago, when I was working as a producer for a video game. I used the phone all the time, because I was constantly moving around the office, almost never at my desk. But my phone seemed to need to be tethered to my desk, charging, for half the day. Even those battery cases sometimes weren’t enough, and I decided then that the world (or at least me!) needed a better option!” –Justin Leader, CEO

Wait, but how?

Risks and Challenges

Structural Integrity 

Although Fat Battery is a relatively straightforward concept, it doesn’t come without some challenges. For one, the back piece of an iPhone isn’t just there for looks. It actually supplies structural integrity to the phone and is deliberately crafted in such a way that it doesn’t block antenna signals, so we’re working with expert industrial designers to produce high quality replacement backs that will provide both function and style.

Heat Dissipation 

All computers, of course, generate heat. Heat in the iPhone comes from both the chips and the battery, and the iPhone back is important in dissipating it. Because Fat Battery is larger, it will generate more heat with less surface area to distribute it, so our designers will be working on a back designed to provide even greater heat dissipation.

Charging Circuitry  

In the iPhone, like most cell phone battery setups, there is a cell, which holds the power, and a PCM circuit. This Protection Circuit Module protects the battery from over-charging and over-discharging, as well as protecting the rest of the phone from the battery. In our prototype, we are able to use the iPhone’s existing PCM, but we will be continuing to investigate this.
