Is your D4 battery holding its charge?

It's the battery chemistry

Yes, all batteries self discharge. Yes, the camera is never really "off".

But my experience with the D4 batteries mirrors yours and is a bit different from my experience with the D2x. The D4's batteries self discharge a noticeable bit more than the D2x's. Not enough to change how I use the camera, but enough that I've noticed it.

There are a number of possible reasons. 1) I could be hallucinating about it (time seems to fly by faster as I get older), 2) the D4 batteries are slightly smaller capacity than the D2x or D3, 3) the battery formulation / charging parameters / charging circuitry are different and may be tuned differently and 4) the D4 may have a higher idle draw than other cameras (phoning home to the NSA?).

You're not hallucinating, and it isn't a difference in camera body.

There is a significant and consistent difference in self-discharge rate between the EN-EL4/a batteries and the new EN-EL18 batteries, even for batteries sitting outside of the camera. The EN-EL4 variety can be left sitting for months with minimal self-discharge, whereas the EN-EL18 will lose the majority of their charge in a couple of months.
