Phantom 2 Owners when do you charge your batteries?

I have noticed that the battery reading on my Mini IOSD shows a charge of 924% when I start flying daily. My normal routine is to charge my pack and download all video from my GoPro after each flight and I fly daily. So the packs sit about 24 hours fully charged between flights.
I wonder how much the Gimbal zaps from the pack. I have the H3-D2
