iPhone的电池容量值以mAH为单位

Question

我想知道如何获得Mha for iPhone/iPad电池的数据容量。 我会把它们放在我打算放在appstore上的应用程序中，然后我不能使用IOKit。 有谁知道我怎么能得到这些值？

Answer 1

batteryLevel 

The battery charge level for the device. 
@property (nonatomic, readonly) float batteryLevel

Battery level ranges from 0.0 (fully discharged) to 1.0 (100% charged). Before accessing this property, ensure that battery monitoring is enabled. 

If battery monitoring is not enabled, battery state is UIDeviceBatteryStateUnknown and the value of this property is –1.0.

    Available in iOS 3.0 and later.
