| <h2>Description</h2> |
| <p> |
| This test validates that all of the BatteryManager attributes exist and are set to their correct values when battery is discharging. |
| </p> |
| |
| <h2>Preconditions</h2> |
| <ol> |
| <li> |
| The device is unplugged from the charger before this test is run. |
| </li> |
| <li> |
| The battery must neither be empty or full, nor reach empty or full capacity during the test. |
| </li> |
| <li> |
| Waiting for battery level change to fire levelchange event, maybe need a long time |
| </li> |
| </ol> |
