It's warming up in Az already (highs in the mid 80's daytime). I thought last week I already got the 5% upgrade (in pure power off the line), but now realize it's just Az heat.
When I deep cycle, I go down to 1 mi remaining (don't leave it there for long, but it's also OK to do, done it 3 times total now). I've only put 1,500 mi on Superchargers since purchased in April 2018. The rest has been short trips to the store up to 10 mi max. typically 2 mi. is all.
I drive like it's a racecar (which is it) - on my second set of tires in the back. They say how you drive can affect range... really? Maybe I baked the battery chemistry in a good way last summer, 110F and ON IT all the time. Still on version 2019.5.15 so I don't believe I have the battery upgrade yet. Getting better all the time!
FYI, I let my car sleep as much as possible at night. Pay attention to those sleep controls from TeslaFi. If you don't let your car deep sleep, you will lose range (I am told by Tesla Service) because it's still being used. Shut 'er down folks.
The range creep below suggest just warming temperatures in Az. It was so cold this last winter, It's warming finally! I had to wear long pants 3X this winter... that's bad.
I charge to 90% every night now (for the past 4 months) and only did it about 3x per week prior. It doesn't get the full 48 Amps either as I'm using the stock charger at 32A. Maybe this "trickle" charger works better? Too many variables.
