如何在 iOS 中获取大量电池信息？

Question

我想知道是否可以在 iOS 中接收有关电池的信息，例如：容量 (mA)、电压 (V)、循环计数？

我知道 UIDevice 类，但电池电量不是我想要的。

Answer 1

试试UIDeviceListener，它基本上UIDevice从不使用任何私有 API 的情况下窃取整个电池数据字典。它公开了大量信息：

{
    AdapterDetails =     {
        Amperage = 1000;
        Description = "usb host";
        FamilyCode = "-536854528";
        PMUConfiguration = 1000;
        Watts = 5;
    };
    AdapterInfo = 16384;
    Amperage = 1000;
    AppleRawCurrentCapacity = 1279;
    AppleRawMaxCapacity = 1275;

    );
    IOMatchCategory = AppleD1815PMUPowerSource;
    IOPowerManagement =     {
        CurrentPowerState = 2;
        DevicePowerState = 2;

    "battery-data" =     {

        "0004-default" = <...>;
        "0005-default" = <...};
    "built-in" = 1;
}

我对此可能是错的，但使用公共 API 这是不可能的。根据UIDevice文档，您最多能做的就是获取电池电量、状态并启用电池监控。

2019 年 2 月 15 日更新：看起来 iOS UIDeviceAPI 现在允许开发人员访问设备的电池电量。呼！目前它公开了 4 个不同的 API。从表面上看，这些并不是“私有的”，换句话说，开发者可以安全地使用它们，而 Apple 不会阻止您的应用程序进入 AppStore。

获取设备电池状态

1. var batteryLevel: Float（设备的电池电量）。
2. var isBatteryMonitoringEnabled: Bool（一个布尔值，指示是否启用电池监控（true）或未启用（false））。
3. var batteryState: UIDevice.BatteryState（设备的电池状态）。
4. enum UIDevice.BatteryState（设备的电池电量状态）。
