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.

Android usually tells you charge at 25%. On a normal Android device it says connect your Charger when it reaches that level.
