Its not easy on the battery.

With the new iPad Air 2 and previously using foreflight I had to delete Garmin because of the battery usage. Even with location services off and the iPad sitting overnight, drained 40 percent. I wished I couldve kept it for longer than a day before deleting it... Cant believe others arent having this problem.
