    remaining drops into a warnable level.

  time_remaining_handler($callback :CodeRef)
    Register time remaining event handler called when the power source(s)
    time remaining changes.

NOTICE
    Callbacks listed above do nothing without under the Cocoa's event loop.

    To work those callbacks correctly, you have to use this module with
    Cocoa::EventLoop:

        use Cocoa::EventLoop;
        use Cocoa::BatteryInfo;
    
        Cocoa::BatteryInfo::low_battery_handler {
            # do something;
        };
    
        Cocoa::EventLoop->run;
