BatteryManager运行状况值“ 9”

Question

我从BatteryManager得到一个“ 9”值。这是什么意思？有人知道吗？

这是我想要的代码：

int health = batteryIntent.getIntExtra(BatteryManager.EXTRA_HEALTH, 0);

研究领域。

BatteryManager Health values

BatteryStats.Java

BatteryManager.java

根据documentation android在常数以下使用。

enum {
    BATTERY_STATUS_UNKNOWN = 1,
    BATTERY_STATUS_CHARGING = 2,
    BATTERY_STATUS_DISCHARGING = 3,
    BATTERY_STATUS_NOT_CHARGING = 4,
    BATTERY_STATUS_FULL = 5,
};

enum {
    BATTERY_HEALTH_UNKNOWN = 1,
    BATTERY_HEALTH_GOOD = 2,
    BATTERY_HEALTH_OVERHEAT = 3,
    BATTERY_HEALTH_DEAD = 4,
    BATTERY_HEALTH_OVER_VOLTAGE = 5,
    BATTERY_HEALTH_UNSPECIFIED_FAILURE = 6,
    BATTERY_HEALTH_COLD = 7,
};

  

    

根据我的研究，我没有看到“ 9”的值。这种价值并非总是会出现，很少会出现，但我无法发现这种情况。
