It doesn't matter how the discharge happens. The bad epub will just have drained the battery quicker which is handy when doing the calibration.
Oh. Gah. If it is
calibrated, it's being strange deciding to hang around 47% for a few days. Doesn't seem like a linear drain at all (with hardly any irregular use, I've left it in sleep mode as much as possible). I suppose I really will not know until it loses its charge again.
