iPhone的電池容量值以mAH爲單位

Question

我想知道如何獲得Mha for iPhone/iPad電池的數據容量。 我會把它們放在我打算放在appstore上的應用程序中，然後我不能使用IOKit。 有誰知道我怎麼能得到這些值？

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.
