Of all the ways I’ve seen to try and combat Pokémon Go’s battery drain, this is easily the best.


It’s a custom, 3D-printed Pokédex case that has blinking lights, holds a phone (in this case, a Galaxy S4) and, most important of all, is also packing a 2,600 mAh battery, which depending on your other apps and usage would probably double your time between charges.

If you’ve got a Galaxy S4 (or just want to take a look), user NPOOLE posted the design to custom electronics site Sparkfun.

Shame about that Team Valor cover, though.
