Here is a short video on the LG G4 Mophie case - it adds the extra battery power without having to power down your device and switching out the removable battery. The Mophie case allows your charge your device on the go with no USB cord. It does add some bulk to the phone (equivalent to an Otterbox or rugged style case) and also offers some protection for the device. What are you doing to boost your battery life - spare batteries, USB cords everywhere or are you pleased with the battery life and are getting thru the day with no problems! Feel free to post your thoughts below!
