When it comes to cases, Otterbox does a very nice job of keeping your phone safe. In fact, if you're a Galaxy Nexus user, Otterbox has created 2 cases just for you. The Defender and Commuter cases are $49.95 and $39.95 respectively. Both cases have two layers of protection, and the Defender series case comes with a belt clip and doubles as a stand. As you can probably tell by the name, the Defender case protects more than the Commuter case. However, the Commuter case will be thinner and sleeker and fits into your pocket more easily.
A lot of people have been asking me whether or not the Galaxy Nexus with the extended battery fits in the Otterbox Commuter and Defender cases. My answer to you, absolutely yes! Obviously, since the extended battery adds a millimeter or two to the total thickness of the device, the case will not fit 100% normally. However, the only difference once you put the extended battery in, is that on the commuter case, the second layer will stick up just a tiny bit. But as the second video displays, you can take off the extended battery back and everything will fit fine.
