I have a brand new Hero7Black. Charged batteries in the double charger overnight before first power up.
Yesterday, I turned the camera on for the first time, upgraded the firmware, poked around the menus.
Since then (24 hours), I have only turned it on to review menu settings and explore. I turned on ProTune, and have it set to 1080P, Linear with 0.5EVComp - everything else is default. 64GB Sandisk Extreme card.
I have not filmed a single minute of video, yet the battery is already down to 25%
! I have only turned it on to look at settings - I'm very concerned about what I'm going to experience once I start filming! I have two batteries - am I going to need to purchase four?!

The simplest solution to this is to fully charge your camera, when it gets to 100%, remove the battery and reinsert the battery. This prevents a power drain. However if you start the camera and turn it off again, this will initiate the power drain.
You can also perform a manual update of the firmware, this addresses some of the power drain causes:

I've had the unit off and plugged in for a little less than an hour, turned it on to check for any further updates with the iPhone app - appears to be totally up to date.
Battery is now charged to 93%. I will let it fully charge, then take it out to play and see what kind of stamina it has.
