Tesla Motors Club

I just picked up my brand new LR+ Model X last week. I'm convinced that the new battery technology is either in my vehicle OR they've done something different to affect efficiency from a driving and charging standpoint. I recently dropped my Tesla off to have some custom work done to it. I dropped it off with 240 miles of range remaining. It's been 3 full days of work (doors open, trunk/frunk open, etc) and my current range on the vehicle is 215. I remember in the past, a Model X could drain that much in several hours with sentry on. Additionally, when I charge on a 240V at home, I am able to charge much faster to get to my set percentage. Am I reading too much into this? Does anyone else have a brand new Model X (within the last month) that also feels this way?

edit: I should add that I know it hasn't been plugged in since I dropped it off (I've been checking constantly).
