Vacation Mode



Offer a vacation mode for minimal vampire drain – available from the main screen and remotely via an app.


Something that will allow the vehicle to still be accessed from the app without removing it from sleep. Also a way to put it in this mode and pull out if by the app for those times it has been overlooked.

Moderator: The allowance of celular access is one of the major causes of vampire drain. Perhaps a better solution is once activated, the cellular connection is lost to conserve power.  Also, improved designs in the newest cars (Model 3) further reduces vampire drain, so the feature may not be necessary on the M3 and future models and refreshes.

I'm not certain, but isn't charging the battery the main source of vampire drain.  If that is the case, you eventually would have to replenish that energy when the car comes out of vacation mode.
The car remains alive.. "Vacation mode?"  I think not.
Before I went out of the country for a month, I charged my 2018 Model S 100D to 90%, then set my charging to 80%, and left the UMC in the charge port.  The battery only drained and did not charge.

I'm a new Tesla owner, so it's possible I did not understand what to maintain a specific charge while the car is not in use for long periods of time.  I thought that setting it at 80% and leaving it plugged in meant that it would charge whenever the battery dipped below 80%  to maintain an 80% charge.
“The allowance of celular access is one of the major causes of vampire drain.”

Dubious statement. A typical smartphone battery in 2018 stores around 3000 mAh of charge at around 3.7 volts, equating to about 11.1 watt-hours of stored energy. The Tesla Model 3 Long Range battery packs store about 75,000 watt-hours of energy. If a typical smartphone can remain on standby for a day, then a smartphone running on the Model 3 LR's batteries could remain on standby for about 6,757 days. In other words, the cellular radio is NOT a major cause of vampire drain.
The specific implementation could be left to Tesla engineers, but a one-button Vacation Mode while parked for many days without a power cable would be useful. Think about the analogy of “Airplane Mode” for a phone, done for different reasons but with similar effect, or “Low Power Mode”.

This concerns me if I plan to park at the airport for a multi-week travel, in fact now I am hesitant to do so with a Tesla and instead would likely opt for limo service. I really prefer the convenience of parking, and eventually car parks will probably have lots of outlets supporting trickle charge, which is all you really need.

TeslaFi has a mechanism to put your car to sleep when parked for a long time, and maybe all that means is that they stop pinging it, haven’t looked into it much.
