Mine tops off from ~40% to 90% overnight on the 240V setup. Roughly 7 hours plugged in, though I'm never actually watching. My buddy has the same car and says his takes noticeably longer, and we can't figure out why. Same year, same trim, both on 240V home setups.
I'm suspicious it's his charger amperage (he's on a 30A circuit, mine is 50A) but he swears the app says the same rate as mine.
Curious what everyone else actually sees at home. Especially if you can tell me your circuit amperage -- trying to figure out if my friend has a real problem or if we're both fine and imagining a discrepancy.
