Pretty minor fixes, to be honest, and since I am rather fond of my 6D as it is, along with my 3rd party batteries, I think I'll have to pass. So far, I've never had a problem transferring images to my phone, but to be honest, it's not something I do often.
Canon would have to make the next firmware change rather tempting if it wants me to discard my non-OEM batteries, since, as it is, my 6D is a dream
On the battery life, yeah, GPS not turning off is annoying when I forget about it
