Doubles your Galaxy S4 battery life, protects your phone at the same time
Here's a quick look at the ExoLife S4 battery case from Exogear. As the name implies, it's a battery case for the Samsung Galaxy S4 that packs an external 2,600 mAh battery into a fairly svelte case.
It's a simple enough design. The case comprises as thin front that snaps onto the beefier rear. The phone slides into that rear search and connects via microUSB, just as you'd expect. It's a pretty good fit, and at no point were we worried about the case coming apart. We had no problems with sharp edges or anything like that. Nice build quality. Just make sure you get it snapped in place all the way around.
