I'm not claiming that leaving the feature on is a problem. It just
didn't seem logical to me that leaving the feature on does not result

How cause any significant battery drain if the data is in the dedicated

to a remote desktop and only records changes.

Surely, the only way that you'll find out this is if some "third party"
rewrites it for you...
