Battery decline when parked

[Klepper]

I don't find mine drops either.

In this situation, with the car "out of your possession", hard to know for sure what's going on. Lots of variables.

I saw mine drop around 1-2% a day when at the detailers getting PPF. I figured it was doors opening preheat/precool, lights and other things the does "intelligently".

Some places will put the key on the windshield, could something like that stop the car sleeping?

Just to add, if pre-heat / cool is disabled, my battery SOC remains fixed. I left the battery at 80% SOC for two weeks without any drop.

Just to repeat, mine is disabled and the car is not being accessed at all whilst sitting at the shop (multiple remote checks each day show locked and parked) - the fender arches were removed Day 1 and are being sanded/prepped for paint away from the car so again, I am fairly certain that this is not the reason for the battery drop .

Earlier posts with suggestions relating to arrival batt temp and subsequent very cold (or big heat drop) nights are likely the cause. My SoC seems to have flattened out today i.e. no move lower than 47% which likely supports this further.

Cold temperatures can cause large drops.

Sorry to bring this back, is it normal now to see a battery drain in consistent temperatures? I just got the ana6 update and my battery drain is now a consistent 1percent every 2 - 3 days. Before the update, I could leave it for a week+ without any drain.

The most important question here is... Is your 12v fully charged?

Because if now there's an update that ensures the 12V battery is fully charged, I don't mind 1% main battery every 2-3 days to be totally honest.

Rather get back to a working car and less SOC then a fully charged brick.

Mine’s been in the dealer waiting for a heater (now fixed) for 3 weeks. It lost 1% in that time.
