I'd love to see where you've seen that reported for Lithium Ion batteries, as the recommended storage charge level (where the charge level has the least effect on the life of the battery) for Lithium Ion batteries is 40%.
At a 40% charge at 25 degrees C, your battery will naturally lose 4% of its capacity in a year. At 100% charge at the same temperature, it will lose five times that (20%).

Lithium Ion Polymer battery manufacturers recommend discharging the battery to 50% for storage purposes. That doesn't sound anything like "never letting it get discharge 50%." You're intentionally discharging it to that level with the understanding that it will slowly discharge in storage.
