Over time, your battery will start to degrade a little bit, and eventually, you’ll get worse battery life than when you first bought it.

i-Blades Smart Case

i-Blades Smart Case

First up is a unique case from the guys at i-Blades. They actually call it a "smart case" for one of the smartest phones on the planet, the Galaxy S8. 

The i-Blade Smart Case for the Galaxy S8 does a lot more than just extend the battery life. It's a traditional thin case that offers decent protection, but then there are four connection points on the back that allow modules or "blades" to snap on. It isn't extremely pretty, but the blades add a lot of value. 

For $99 the i-Blade Battery attachment adds 12 hours of battery life, 64GB of storage (so 128GB total) and a second microSD slot for even more storage. Technically with their case, the Galaxy S8 can last nearly two days and have over 600GB of storage in total. Pretty neat right?

The case also has sensors to monitor air quality around you, and there will be more snap-on blades released at a later date.
