[QUOTE="technologist, post: 321823, member: 4134"] Actually, that might be contributing to the battery's loss. Deeply discharging a lithium-ion battery weakens it... ([URL=http://www.batteryuniversity.com/parttwo-34.htm]Source[/URL]) Calibrating a battery is not "good" for it; it's [b]necessary[/b], because it, well, [i]calibrates[/i] the power-level meter. Otherwise, they'd get out of sync with the battery's true capacity, and wouldn't give an accurate reading. (And you'd end up draining it more often, accidentally.) [/QUOTE]
