Hi @sKrushinsky and welcome back to the forum.
I have had my video doorbell installed since the 22nd (I think, give a day)
It is on my patio door that sees little activity. I put it out at 100% charge and within a matter of 4 days it was down to 83% I checked it a couple of days later and it was at 86% and today was at 87%. I know weird it’s going up vs down.
The VDBP sports some pretty hefty batteries, and as you implied the more activity, less cool, down etc… the more drainage you will see.
I’d suggest giving them a full charge then monitor if one is wildly off from the other outside of activity and settings you may wanna give support a call.
But to me (and I’m just a user too) what you describe seems fairly normal.
Happy New year!
