That's degradation rate in capacity, not overall capacity. But trading off 40% of the energy for a 25% lifetime increase is not a great trade for everyone.

You would then consume almost 2x of those cycles just recharging to make up for the lost capacity.

Capacity or longevity?

Both, as a battery ages from use its capacity diminishes which is why it runs out faster.
