  1. About 50% ✔
  2. Full, 100%
  3. Totally empty, 0%

Why: Apple says don't store a device fully charged or fully empty. An empty battery can sink into a deep discharge and stop holding a charge. A full one can lose capacity faster.

Huh, didn't know that: For storage over six months, Apple says charge it back to 50% every six months, and keep it under 90°F.
