Vishal Mishra closed CB-8916.
-----------------------------
Resolution: Fixed
With the [W3C Device Orientation
API|https://www.w3.org/TR/2016/CR-orientation-event-20160818/] now being
supported on iOS, Android and Windows devices, this plugin is not needed any
more. Migrating from this plugin to the [W3C Device Orientation
API|https://www.w3.org/TR/2016/CR-orientation-event-20160818/] is explained in
this [PhoneGap blog
post|https://blog.phonegap.com/migrating-from-the-cordova-device-orientation-plugin-8442b869e6cc].
> Huge memory consumption in iOS 8 with compass plugin when filter parameter is
> not specified

> Key: CB-8916
> URL: https://issues.apache.org/jira/browse/CB-8916
> Project: Apache Cordova
> Issue Type: Bug
> Components: cordova-plugin-device-orientation
> Affects Versions: 3.7.0
> Environment: Cordova iOS 3.7.0
> JQuery Mobile 1.3.2
> iOS 8
> Reporter: wei zhang

> Hi, I found a bug that occurs if the filter parameter is not specified. It
> triggers a large memory consumption in the app and ultimately the app will
> not respond to user input.
> My function tracks the direction for a list of places, and updates the
> heading in real time (one for each place). The code below is my function.
> When I tested my app(built against iOS 8 SDK) on both iOS(iPhone5 iOS8)
> emulator and iPhone 6(iOS 8.0.2), the memory consumption increased
> significantly when the function was called. The app failed to respond after
> about 1 minute 40 seconds, and the memory usage was around 270 mb(I was
> monitoring in XCode). The console log Compass Count indicates that the app
> usually dies when count reaches around 960.
> The issue occurs when the app is built against iOS SDK 8.1. However the same
> code runs fine in the app when it is built against iOS 7 SDK (there is no
> noticeable increase in memory consumption).
> Could you please look into this? Thanks
> function activateCompass(frequency, callback){
> var frequency = frequency || 100;
> console.log("frequency is " + frequency);
> var options = { frequency: frequency};
> compassHeading = navigator.compass.watchHeading(
> function compassSuccess(heading) {
> console.log('Compass Count: '
> + compassCounter++);
>
> callback(heading.magneticHeading);
> },
> function compassError(compassError){
> console.log('Compass error: '
> + compassError.code + ' Counter is ' + compassCounter++);
> },
> options
> );
