Continious location fetching in iOS 9 devices

HI,

In my application i used location services to continuously fetch the location. its working good in iOS 8 devices. But when I checked in IOS 9 devices the application gets slow.

Titanium.Geolocation.addEventListener('location', getCurrentLocation);

I have used this location service to continuously fetch the location . Inside getCurrentLocation function I used this to get the lcoation Titanium.Geolocation.getCurrentPosition().

I have used Appcelerator sdk 4.1.0

please advise me to fix this issue.

Thanks
