Bought this as a gift for wife and daughter after buying one for my iphone last year. Now they never run out of power during the day. For size, they keep it off in their purse until needed. They made me promise to buy them one for their Samsung's after I picked mine up on sale and showed it to them. In the past I had to keep my phone off at work due to dead zones in my building. Now I can leave it on so I don't miss messages when passing through a reception area. By the end of the workday, I can recharge with it and don't worry about forgetting to plug it in at night as it will last through the next day.

The LifeCHARGE S4 charger works well and does what it is supposed to do. However, when its in use it can get a bit hot on the back side to the point that one time when I was using it, my phone, and my GPS with maps it shut the phone down from overheating. (the phone said why it was shutting down just before it did it.) This unit also gets hot to the touch on the back when it is charging, but after charging is complete it cools down again. A note: its not "Too hot to touch", just what I would consider hot to the touch.

Having an external battery right in the case is fantastic! It minimally adds length and depth to the phone. Great to have extra battery power without having to remember to bring an extra battery/extra piece.
