Answer 1

Well the Apple docs say this:

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

So your code should be like this:

[[UIDevice currentDevice] setBatteryMonitoringEnabled:YES];
float batteryLevel = [[UIDevice currentDevice] batteryLevel];

//This will give you the battery between 0.0 (empty) and 1.0 (100% charged)
//If you want it as a percentage, you can do this:

batteryLevel *= 100;

Hope this helps!
