So I've only had this new-to-me 2014 i3/REX for a couple of weeks. Usually I drive it during the day and plug it in at night. Yesterday I had to take the truck out of town for the day and since the i3 sits behind it I moved it out into the driveway and left it there unplugged. It was sitting at 100% battery at the time. This morning I got in the i3 and it is showing 90.5%. I lost basically 10% of my battery in 24 hours? Car was sitting outside with temp during the day in the low 70's and the high 50's overnight. Is this normal? If I left it sit unplugged for 10 days would the battery be at 0%? This is disturbing...
