Galaxy Nexus with the extended battery pack and the OtterBox Defender
This phone is a little bit on the large side due to the big screen ... however it does everything a user needs on a smart phone with ease.. Email, Calendar, Phone, FB.. and a whole heap of apps from the market
The OtterBox case is solid and gives the flimsy(good thing) phone a rugged user profile..
The extended battery fits without a problem with this case and the screen protector on the case is a bonus (all in one package)
the extended battery gives me a full days usage on a single charge ( i am a fairly heavy phone user)
