Love our Spark we got for the kids for Christmas (i get to use it more than the kids   Just learning all the tricks, but im using masses amount of internet data on my phone and iPad.  Can it be the drone?  Would it be the Video Cache?  Im IT illiterate.  Thanks anyone that may know.

Switch off WiFi and cellular when you fly as not needed though having cellular on whilst flying only uses a couple of hundred megs.

Are you flying mobill data on with sat view?
Are you syncing the flight records often? And all?

Edit :
the video cache is caching the video from the spark to your phone.
As long you not use the 'live streaming into the internet' function, that is only for saving 720p video on the phone

Thank you.  I'll check those out when I get home.  Much appreciated
