Your trusty iPhone is always there when you need it. Say you’re in a new town and you needed to turn on the GPS to find your way only to find it dying on you moments later. The battery life on the iPhone 4 can be pretty dismal when GPS, Wifi or Data Roaming is turned on. Thankfully there’s some pretty decent battery cases that comes in all kinds of sizes which combines both external battery and the case. Here are some of the best battery cases for the iPhone 4 that not only give you battery boost but also protection from bumps and scratches.
