ok.....updated to V10. Played with everything turned on StandBy Mode (I believe it allows your car to be "Summon Ready" so its not as long a wait). plugged in my car, regular 110v outlet. Normally my charging time was around 14 hours but this time it was 19. made me raise an eyebrow so I checked my phone app 3 hours later and my charging time was almost the SAME. ....so after wracking my brain I figured it must be that StandBy mode.....went to the car, unplugged it, turned off StandBy mode plugged it back in and viola, the charging time went to 14 hours. I have not investigated to see if that is indeed the case but I'm sure this may be of interest to those not as lazy as me.
