I'm sorry to disappoint you here but every cycle counts nevertheless how
far it was charged/discharged. In that moment you switch from AC to battery,
or otherwise round one cycle is lost.
Nevertheless LiION batteries degrade over time even they are not used at all.
Taking all this into account 69% of remaining battery power after 32 month
of battery life is not bad at all. Normal Laptop batteries have a lifetime of
about two years, depending on the manufacturer. My battery died (less than 1h
or 20% left) after 4 years. I used the battery a lot but unfortunately I don't
know the cycle count.
