I use an extended battery. I have the black Verizon case/holster combo (with the plaid design on the back.) The case fits it, but it is tight. It also fits in the holster, but again, very tight. I'd like something that fits the battery better, and is professional-appearing, because of my job. I could modify the holster to fit better, but I'm more worried about the tight-fitting case over the extended battery. Suggestions?
