Vampire Drain is still a major downside after 5 years

An iPhone can keep LTE open on it's 2Ah battery for over 24 hours when you don't use the screen.

In addition it has temp sensors running and is doing a lot more work.

Lithium-Ion itself has almost no self discharge, so that's not really an issue here.

Keyless entry can be done by ICE cars and their 12V battery without problems, so why can't a Model S/X?


Indeed, the e-Golf is much better in this area.

Do you have passive entry turned off? Seems like that would save quite a bit of power, and most other cars don't have that feature.

Ha.
I gave up on sleep mode (latency)and do use Teslafi (so pinging car every minute I think).
Here in Canada it is cold. And even the AP cameras are heated all night.
So when I leave mine for a week, it uses nearly 5 kWh AC per day. Wild big number.
I know because I submeter the circuit.
