Very strange vampire battery drain, need experts help.

[Wennfred]

Tonight after turning everything off, I noticed that the Sentry mode switch was on, where you would select Home, Work locations. Almost at 90% of charge, will unplug for the night, will check in the morning for any drain.

91% / 219 Miles...all is off, even WiFi & Bluetooth,

Before I removed USB, of course I did long press on TeslaCam icon till it become grey X. After about 30 sec. I did remove USB. After exploring it, NO Sentry Mode files at all. Zero.

I meant long press to turn off, then leave it like that to test (don’t remove USB).

There you have it, exactly 12 hours of sleep time, Zero loss of range.

So to Summarize what is off:

Sentry mode (turn off switch) not just the red dot on top, its in the Safety & Security page

Data Sharing down in the Safety & Security page, select No to both fields, then select Submit.

Cabin Overheat Protection (off) Safety & Security page

“Keep Climate On” (off) press the Fan icon to see it.

TeslaCam (off) press and hold the camera icon until it flashes and it will grey out. Leave the memory card installed, don’t need to pull it.

Wifi (off) press the WiFi icon and press WiFi settings and select off.

Bluetooth (off) press Bluetooth icon and select Disconnect.

On the media (music) page I set it to phone to ensure Its not getting any radio signal.

Allow Mobile Access is on but I didn’t wake up the car at all in those 12 hours.

Lock the car to shut it down for the night. Press the Lock on the App.

That should do it, give it a try tonight.

Right now, 10:08am WiFi & Bluetooth is active, still no loss or drain, will return in a few hours to see if any.

Two hours later, still at 91% 219 miles, the Bluetooth & WiFi has no effect on battery drain or range loss. Still on 2019.24.4

Will activate Data Sharing now and shut down again, back in 2 hours.

Isn’t that two pictures 1 minute apart ... or perhaps 23:59 or 24:01 apart, not 12

9:39am and 9:38am.

Any updates?

After 2 hours with Data Sharing on, it dropped 1 Mile 219 - 218.

After 2 hours with Data Sharing on, it dropped 1 Mile 219 - 218.

Using the dashboard display to measure loss over 2-hour periods is very VERY unscientific.

One 2-hour period that shows “0 miles lost” could be MORE than another 2-hour period that shows “1 mile lost”.

e.g.
101.49 start (reads as 101)
100.50 2-hr (reads as 101 still, but 0.99 miles lost)
100.49 4-hr (reads as 100, but only 0.01 miles lost)

This is made worse by short periods where rounding can effect the outcome by almost 100:1 ratio as above.

Get TezLab and use their deepsleep function and see if that helps. I use it all the time and that helps save my battery life by a lot.
