Leaked Next Gen iPhone has a Higher Battery Capacity?

Another day, another rumor about the next generation iPhone which might be unveiled pretty soon. This time, a picture shows a battery that is supposedly to be the battery for the next gen iPhone (iPhone 5?).

It has a slightly higher capacity of 1440mAh. No other information at this moment. If this is real, I guess Apple is not the same Apple when Steve Jobs was around. Usually, there is no way a component or any information of a new product that could be leaked online (except for iPhone 4 that was lost in a bar). Now, with so many reports, I am beginning to think/accept that these parts are for the next gen iPhone. Please tell me I am wrong.
