Have you tried a Mophie?

I went to Verizon a few days ago and made the switch from AT&T. I upgraded from my iPhone 4S to an unblocked iPhone 5. While I was there, they sold me on this Mophie pack made specifically for the iPhone. I went ahead and said I would give it a shot. Let me tell you, I love it! It functions as a battery extender. Basically it gives your iPhone extra juice, extra battery. The way it works is you slip your phone into it like a case. When your iPhone runs out of battery all you have to do is flip the case over and switch on a button. Boom! You have another full battery! You don't have to take it apart to charge it. Once you plug it in to charge it charges your phone at the same time. It's awesome! If you have a problem with the battery of your iPhone running out of life quickly this is the best solution! It is a bit on the expensive side but I think its worth it. There are two kinds, one is 80% at I paid $80 for it. The other is 100% and I believe it's $90. But I tell you, you won't regret it if you get it! If you do feel free to share your comments with me!
