I'm one of those poor souls still fighting my condo board to let me install an outlet. So, I've been going almost a year now with no home charging and therefore do everything I can (always connected off, energy savings on, range mode, no preconditioning) to minimize vampire losses to reduce the charging trips I have to take. In my pre-refresh December 2015 90D, I would routinely see 2-3 miles per day lost to vampire drain overnight. This is in a heated garage kept around 65-70, so nothing would be kicking on to modify the pack temp. I was on whatever software version was right before 8.0 when I sold it. Now I recently acquired a May 2016 P90DL (107xxxx-C battery pack) and my vampire losses are essentially 0. I've seen it sit for 18+ hours and still show the same range. I've never seen more than a 1 mile change, so the difference is dramatic. The only things I can think of that have changed: - pre-refresh to refresh - regular 90 to a P - different chemistry in the 107xxxx-C packs? - software version 8.0 - something else? Has anyone else noticed a difference in vampire drain since 8.0 came out? With a couple reports from others we could probably pinpoint where the change occurred.
