POWER_SUPPLY_STATUS_NOT_CHARGING is used for AC connected, but battery not charging (e.g. because battery temperature is out of acceptable range). If you are discharging use POWER_SUPPLY_STATUS_DISCHARGING. You should just ignore the FULLY_DISCHARGED bit in the status property. If you don't want to loose the information about fully discharged battery add POWER_SUPPLY_PROP_CAPACITY_LEVEL, which maps: BATTERY_FULLY_CHARGED => POWER_SUPPLY_CAPACITY_LEVEL_FULL FULLY_DISCHARGED => POWER_SUPPLY_CAPACITY_LEVEL_CRITICAL otherwise => POWER_SUPPLY_CAPACITY_LEVEL_NORMAL -- Sebastian
