Maybe when the phone thinks it is at 100% capacity, it really isn't.

I got the Boxwave stand with spare battery charger. I like it and will describe it more elsewhere. The spare battery part has an LED that switches color. But the phone part, the LED never changes color. It charges and charges and charges until the phone beeps, displays at exclamation point inside a circle in the middle left of the taskbar (top) and a Notification appears in the lower left. When you touch it, a popup dialog is entitled "Information" and a message in the box says "Charging is Complete".

Never got that message before with the Samsung A/C charger so I wonder if there is an extra 10, 20, 30% to be added to battery capacity? I'm only on my first charge with the Boxwave charger but it doesn't seem to be going down as fast (maybe all in my head).
