Hi, I bought this: http://store.apple.com/uk/product/TR823LL/A?mco=NDcwMDA0Nw a couple of months ago. I have only used it a few times, the first few times i used it i couldn't get one full iPhone charge out of it. I left it for a couple of weeks, used it again and the same happened. I used it today, and it charged my iPhone 3G up fully using only 2 out of the 5 battery indicator LED's, meaning theoretically ill get another charge and a half out of it (in theory, i doubt this will happen, maybe anther charge). Anyone else got one of these batteries? What are your usage stats like?
