Good to know. But that stinks, because if I leave my iPad Mini4 on all the time, it will never be charged up when I'm ready to fly. And leaving it plugged in all the time is bad for the battery, long term. I'm disappointed there is no way to save the maps.
Is there any way to leave the iPad powered on, but have it in some kind of "deep-sleep" mode that doesn't drain the battery? Ideas?
Thanks for the informative thread.
