在iOS上获取电池健康信息

时间:2016-03-15 23:33:54

标签: ios objective-c iphone app-store battery

app-store中目前有应用程序(因此不需要越狱)告诉您:

  1. iPhone上电池电量的确切百分比值。一世 已经尝试过Apple的官方Code Sample,虽然它告诉你iPhone何时充电和放电,但它给我的价值为5%。这些应用如何获得电池百分比的确切值?

  2. Battery Health等应用程序显示

    • 当前最大容量 vs 制造商的容量
    • 当前出院率
    • 终身电池循环次数
  3. 同一应用程序还提供有关手机充电时的以瓦为单位的充电率的信息(查看图像)和当前充电器的额定功率

  4. Application: Battery Health screenshot 1 Application: Battery Health screenshot 2

    当[UIDevice]提供的信息非常少而且几乎没有关于电池运行状况和性能的信息时,这些应用程序如何获得有关电池运行状况的详细信息。

我已经开发出一种解决方案,可以让您在不调用任何私有API调用的情况下获取此信息(尽管我当然无法向Apple承诺批准它)。

虽然有问题的信息确实来自IOKit,但我找到了一种不依赖IOKit的方法。我的解决方案完全没有任何私有API。相反,我开发了一个名为UIDeviceListener的组件,可以有效地从UIDevice劫持IOKit数据。

尝试一下,我已经整理了一个简单的示例程序:https://github.com/eldoogy/PowerData

作为一个例子,这里是它检索的IOKit字典往往看起来像(注意它可能因iOS版本和设备型号,生成等而异):

此类应用程序很可能使用IOKit框架,该框架在OS X上是公开的,但在iOS上是私有的(Apple不允许使用私有框架用于App Store应用程序,尽管有时在审核期间可能会忽略它)。 / p>
