1. Demo 下载

2. 获取电池电压

// 当前电池电压
import static android.os.BatteryManager.EXTRA_VOLTAGE;

    private  BroadcastReceiver mBroadcastReceiver = new BroadcastReceiver() {

        @Override
        public void onReceive(Context context, Intent intent) {
            if (null == intent) {
                return;
            }

            String action = intent.getAction();
            // 当前电池电压
            int batteryVolt = intent.getIntExtra(EXTRA_VOLTAGE, -1);

3. 电池电压高

// 过电压
import static android.os.BatteryManager.BATTERY_HEALTH_OVER_VOLTAGE;
// 电池健康情况
import static android.os.BatteryManager.EXTRA_HEALTH;

    private  BroadcastReceiver mBroadcastReceiver = new BroadcastReceiver() {

        @Override
        public void onReceive(Context context, Intent intent) {
            if (null == intent) {
                return;
            }
            int health = intent.getIntExtra(EXTRA_HEALTH, BATTERY_HEALTH_UNKNOWN);
            
            if(health == BATTERY_HEALTH_OVER_VOLTAGE) {
                // 电池电压过高，一般触发的条件是充电器电压达到 6.6 V
            }

查看底层上报的值-BatteryServiceConstants.h
frameworks/native/services/batteryservice/include/batteryservice/BatteryServiceConstants.h:23: BATTERY_HEALTH_OVER_VOLTAGE = 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,
};

即底层上报 health 为 5 的时候，触发电池电压高的警告
