This is unlikely - the battery will prevent itself from being overly
discharged. However, LiIon batteries will lose some amount of capacity
over time anyway. What you're probably seeing is the battery
recalibrating itself (ie, you'd already lost 3% of capacity, and the
battery was just lying to you about how charged it was)
