I can get 700-1000 exposures per battery charge on a freshly charged LP E6N battery, however, if I simply put a freshly charged battery in the camera and let it sit for a week (NO exposures) the battery level goes from 100% to 76%...! GPS checked as disabled...any body else getting this?

Even so, the GPS doesn't completely stop. I don't have a 7D Mk II but I have seen reports that battery life is not as good as it was on the 7D.

I've not had a positive result with the battery drain, except to remove the battery whenever I am not using the camera and have also purchased a second battery. I think the high performance of the 7D MKII twin digic 6 processors and the 61 point focus system are high users, but still can't work out why it drains with non use. I have noticed my 70D drains the battery when not being used also.

Just to be sure, I assume that this happens with no lens attached to the camera, too?

What? I don't take lenses off my cameras, that just invites crap into the camera body, two lenses and two camera bodies.

Not even for a test?
Okay, to each his own, I guess. Two bodies and cameras, it is. No need to change lenses.

Sorry for the flipent reply. As I have updated to the next new camera I have kept the last one for my 24-105 USM lens. I used to have one body and three Tamron lenses and that was a recipe for trouble.

I know this is an older thread, but this is exactly what the problem is. If I leave a lens on my 7D MK II, the battery will drain overnight. No lens, battery level didn't change in 5 days. Curious.....

I know I'm a little late to the conversation;; but i found if you simply open the door on the battery that it does turn off the power to the battery. thus preserving the battery through down times. TADA. and i have been using one battery over a weeks time without difficulties...

But you're missing the point. The likely source of your problem is that you're leaving GPS turned on. By default, GPS continues to operate (and drain the battery), even with the camera turned off, so that it doesn't have to spend time discovering where it is, the next time you take a picture.
