电池的寿命

Question

有没有办法或如何获得或知道电池的寿命？我正在制作电池信息，就像在“Battery Doctor Saver Pro”中一样，区别在于我需要的使用寿命。我不知道该怎么做。谁能帮我解决这个问题吗？感谢您的帮助。 :) 到目前为止，这是我的代码，没有我所说的“生命周期”。

private BroadcastReceiver battery_receiver = new BroadcastReceiver() {

        @Override
        public void onReceive(Context context, Intent intent) {
            boolean isPresent = intent.getBooleanExtra("present", false);
            String technology = intent.getStringExtra("technology");
            int plugged = intent.getIntExtra("plugged", -1);
            int scale = intent.getIntExtra("scale", -1);
            int health = intent.getIntExtra("health", 0);
            int status = intent.getIntExtra("status", 0);
            int rawlevel = intent.getIntExtra("level", -1);
            int level = 0;

            Bundle bundle = intent.getExtras();

            Log.i("BatteryLevel", bundle.toString());

            if (isPresent) {
                if (rawlevel >= 0 && scale > 0) {
                    level = (rawlevel * 100) / scale;
                }

                String info = "Battery Level: " + level + "%\n";

                info += ("Technology: " + technology + "\n");
                info += ("Plugged: " + getPlugTypeString(plugged) + "\n");
                info += ("Health: " + getHealthString(health) + "\n");
                info += ("Status: " + getStatusString(status) + "\n");

                setBatteryLevelText(info + "\n\n" + bundle.toString());
            } else {
                setBatteryLevelText("Battery not present!!!");
            }
        }
    };

    private String getPlugTypeString(int plugged) {
        String plugType = "Unknown";

        switch (plugged) {
        case BatteryManager.BATTERY_PLUGGED_AC:
            plugType = "AC";
            break;
        case BatteryManager.BATTERY_PLUGGED_USB:
            plugType = "USB";
            break;
        }

        return plugType;
    }

    private String getHealthString(int health) {
        String healthString = "Unknown";

        switch (health) {
        case BatteryManager.BATTERY_HEALTH_DEAD:
            healthString = "Dead";
            break;
        case BatteryManager.BATTERY_HEALTH_GOOD:
            healthString = "Good Condition";
            break;
        case BatteryManager.BATTERY_HEALTH_OVER_VOLTAGE:
            healthString = "Over Voltage";
            break;
        case BatteryManager.BATTERY_HEALTH_OVERHEAT:
            healthString = "Over Heat";
            break;
        case BatteryManager.BATTERY_HEALTH_UNSPECIFIED_FAILURE:
            healthString = "Failure";
            break;
        }

        return healthString;
    }

    private String getStatusString(int status) {
        String statusString = "Unknown";

        switch (status) {
        case BatteryManager.BATTERY_STATUS_CHARGING:
            statusString = "Charging";
            break;
        case BatteryManager.BATTERY_STATUS_DISCHARGING:
            statusString = "Discharging";
            break;
        case BatteryManager.BATTERY_STATUS_FULL:
            statusString = "Full";
            break;
        case BatteryManager.BATTERY_STATUS_NOT_CHARGING:
            statusString = "Not Charging";
            break;
        }

        return statusString;
    }

Answer 1

不太确定您在这里要做什么，要计算瓦特小时或安培小时，请检查此链接：
http://www.powerstream.com/battery-capacity-calculations.htm
如果您想要当前使用的电池的剩余时间，您需要获取当前的电池电量，然后了解其耗尽的速度，方法是检查在此之前耗尽的速度，然后做出假设或通过知道您将消耗多少电流。

如果您针对您正在使用的确切电池校准代码，将会获得最佳结果

（看起来我被打败了；））

Answer 2

正如我在获取 Android 手机的剩余电池使用时间中所说，您需要获取当前的电池电量并进行工作对当前排水速度进行一些估计。这将取决于处理器负载、屏幕亮度、哪些无线电处于活动状态以及可能的其他因素。

简短的回答，当然可以得到一个估计，但这并不容易，而且可能不是很准确
