This is by design. On battery the load cycle does increase, because it
is useful to allow disk power management: for power saving, and to
protect against falling. It's been calculated that even for pretty
extremely mobile usage, your disk should be fine for a very long time.
On AC your load cycle should not increase (much).

Cheers,
