Swift - Get if battery is charging even at 100%

I am making an app in swift, and I need to know if the battery is charging. I know I can use UIDevice.currentDevice().batteryState, But when it is at 100%, it returns .Full instead of .Charging. It also returns .Full when unplugged on 100%. So is there a way to determine if the battery is charging while at 100%?

Solution

  • You said,

    It also returns .Full when unplugged on 100%.

    But the docs say (emphasis mine):

    UIDeviceBatteryStateFull

    The device is plugged into power and the battery is 100% charged.

    So it seems like the state should change to .Unplugged once you remove power. If you are seeing .Full when the battery is both unplugged and fully charged then that’s a bug (or at least an error in the documentation) and you should report it.
