...having poor battery life.
.
This was only a concept by the way. They're disposable batteries made of cardboard. It was supposedly an "environmentally friendly" design, because they're "biodegradable". But there's a problem. The case is biodegradable, but we can't yet make biodegradable batteries, so the actual BATTERY inside would just murder the environment. And we can't make that much power that small yet for cheap, which is part of the point. So don't expect them any time soon.
