--------------------------------------
Well I don't understand [~shazron]'s comment...but switching to using WKWebView
fixes the issue for me.
> WebView JS execution continues when app executes in background

> Key: CB-12846
> URL: https://issues.apache.org/jira/browse/CB-12846
> Project: Apache Cordova
> Issue Type: Bug
> Components: cordova-ios
> Affects Versions: cordova-ios@4.3.1
> Reporter: Grant Patterson
>
> I'm using a [Cordova
> plugin|https://github.com/happydenn/cordova-plugin-gimbal2] that integrates
> [a third-party SDK|https://docs.gimbal.com/iosdocs/v2/devguide.html] to
> listen for bluetooth beacon sighting events. As expected, my app is allowed
> to run for 10 seconds in the background with the [bluetooth-central
> UIBackgroundMode|https://developer.apple.com/library/content/documentation/iPhone/Conceptual/iPhoneOSProgrammingGuide/BackgroundExecution/BackgroundExecution.html].
> Once the necessary processing is completed, the JS event loop runs until the
> 10-second window closes. Because beacon sightings happen as frequently as
> several per second, the app runs in the background constantly, killing the
> user's battery. I can setInterval() in JS with a 1000ms interval and it runs
> successfully every time; my Angular app runs $digest cycles in the background
> which are unnecessary and quite expensive.
> I think I need a way for the native plugin code to relinquish execution and
> return the app to the background.
