Thanks everyone for replies. I'll double check settings in car when home. Will be fine, not too concerned as it's the wife's car. Luckily don't have to charge the Tesla as often, so home charger is available to her most nights & has access to 2nd car. Just frustrating when you think "wonder what the Mini has decided to charge itself to tonight?", though not the biggest problem in the world.Yes but nobody seems to know how the 12% (approx) is split between top and bottom.
The buffer topic is a thing that will go round in circles IMO, until someone definitively says the where the buffer is split I'll avoid charging car to 100%. But like most things in life everyone has different opinions. Having an EV's for a while, plus wife wants to keep the Mini, battery degradation is a small consideration for us. Though not something to get stressed about. Everyone knows the car has a small range, so if thats a problem. You've bought the wrong car. I just want to charge to what I set it to. Most so I don't get a phone call saying "the Mini hasn't charged again".
