In field usage, with the GPS on, the battery's charge quickly drops. It's going down to 58% or 75% with just a few hundred shots over two-hours. I think that maybe it's the dual processors combined with the GPS. The other Canons with dual processors had much larger batteries.

That's unfortunate. I've pulled my 7DI out of my back to shoot a month and a half after I last charged it and gotten a decent days shooting in before. My 7DI is also good for the 7 thousand+ shots I take in a single day of heavy track work.
Maybe they'll release a firmware update to help with that.
