Is there a difference? Every morning I have been charging to 90% then preheating for 45 mins while charging to 100% right before I leave for work. It's around 5-10 degrees fahrenheit so I still have the dotted line and reduced regen with the occasional banging of the breaks coming loose from being frozen. Does smart preconditioning do any more, such as heating the underbelly getting the battery to the right temp for no limits regen or windshield wiper heating or is it the same as the app? One would think the seats and wipers would be in app, but that could be an update, I just wondered if smart preconditioning was better than me just using the app. I've read on here also that if your schedule varies it doesn't always work the best, any experience from those who work odd schedules?
