is Standby Mode draining your battery?

    ok.....updated to V10. Played with everything turned on StandBy Mode (I believe it allows your car to be "Summon Ready" so its not as long a wait).


    plugged in my car, regular 110v outlet. Normally my charging time was around 14 hours but this time it was 19.

    made me raise an eyebrow so I checked my phone app 3 hours later and my charging time was almost the SAME.

    ....so after wracking my brain I figured it must be that StandBy mode.....went to the car, unplugged it, turned off StandBy mode plugged it back in and viola, the charging time went to 14 hours.

    I have not investigated to see if that is indeed the case but I'm sure this may be of interest to those not as lazy as me.

    Yes. Standby mode drains extra battery. I think it's slightly less than Sentry Mode, but not by that much...

    I turned it off on mine. I don't really see a huge benefit of draining a decent amount of battery just so Smart Summon only takes 1 second instead of waiting the 10-20s for it to connect... but that's just me.

    I have Standby Mode turned on at work along with Sentry mode and I'm monitoring my battery and it is draining a bit more than usually.
    About 2 miles per hour. I'm gonna turn off Standby Mode when I get to my car during lunch.

    I turned my standby mode off. I didn’t even know about it until I looked at the new settings. It looks like the default is on (at least mine was set to on after getting V10).

    I think I lost around 8% of my battery in 24 hours right after V10 was applied and the car not moved. That is a serious waste of electricity...

    So I accidentally left Standby Mode on while car was parked at airport for 6 days. Model 3 LR AWD, ambient temperature was 55F most of the time (Seattle). A bit worrying as I watched battery discharge with nothing i could do, but at least allowed me to calibrate drain caused by this mode.

    Battery drain was 0.236% per hour which is about ¾ mile of range per hour, or about 18 miles per day.

    The big problem here, to my mind, is there is NO WAY to disable this mode from the phone app, unlike (say) Sentry Mode. This is a big hole and its only a matter of time before someone bricks their car.

    If you agree, please join with me in asking Tesla to PLEASE add control of Standby Mode to the phone app. (In this case I did get back to car in time, but it wasnt fun wondering if i would have a dead car when i returned.)

    I'm definitely with you however it may disable itself when the battery reaches under 20%. Either way I hope Tesla see's this and works to make it better.

    Did it actually disable itself at 20%, my car is parked at the airport now and is drained to 21% after leaving it at 50%. I won’t be back for another few days and it would be at 0% unless it turns off at 20%

    Of course it will disable itself.

    You also need to stop checking it via the app so that it stays asleep.
