####Unu Exera Modular Battery Case for iPhone 4 and 4S Red battery statuses are shepherded into greener pastures by a lithium-polymer battery that's built into the back of each hard-shell case. The two-piece case adds up to twice as much battery life to an iPhone 4/4S, resulting in an additional six hours of talk time, 30 hours of music playback, and 240 hours of standby time. A panel slides over the battery slot to keep the case uniform so phones can slide into front pockets or saint bernard casks. The clever case still allows for full functionality while its rugged bumpers protect devices from nicks and scratches. #####Features * Battery case can double battery life of iPhone 4 and 4S * Slim back plate replaces battery panel when additional charging is not needed * Can add up to 240 hours of standby time, five hours of game play, or six hours of talk time * Protects vulnerable devices from nicks, scratches, and buzzard talons * Allows for full functionality * 3–4 hours charging time * Lithium-polymer battery * 1700 mAh * 4.72”x2.44”x.71”
