I am guessing that in order to prevent phantom drain from draining my batteries down to zero, I just leave my car plugged in while I am gone. As soon as the battery goes below 90%, the car will charge itself back up to 90% again.
In case this doesn't work, will my car's batteries drain down to zero if I am gone for 4 weeks? 3 weeks? I mean, should I come back from vacation sooner so I won't come back to a ruined car?
I saw this infographic; https://www.teslarati.com/tesla-model-3-phantom-drain-vampire-loss-vs-s-x/phantom-drain-info-graphic/
The infographic says that my car will lose 5.1 miles per day. So, in 30 days, I will lose 153 miles. Since my car has a 90% charge range of 230 miles, I should still have 77 miles left, even if the car fails to recharge itself while I am gone and left it plugged in?
Bottom line; will my car be ok if I left on vacation for 1 month and should I leave it plugged in?
