Phantom Battery Drain

[Dil100]

My Model Y battery seems to drain approximately 2Km/hour. The temperature is about 2C(approx 34F). I do have Sentry Mode enabled. Is this normal?

With Sentry Mode, yep. The computer is basically always on with that mode.

You can disable Sentry Mode at home if you like... that will drastically reduce consumption in most cases.

So I disabled Sentry mode and what a difference. I now only lost about 4Km of range over a 24 hour period at an outside temperature of -3C. Need to mention that the interior temperature of the car is 3C as it is parked in the garage.

My Stats app says my phantom drain is 0.5 km/hr, around 0-3 degrees here at night, 5-7 degrees in the day. No sentry mode

But what app are you using to monitor this and is that periodically waking up the MY to get data, and causing a lot of that extra drain? Sometimes the act of measuring can make it worse, not letting the MY go to sleep and conserve energy. I tried TeslaFi and never signed up after the trial period was over, could never get it dialed in correctly, it was causing the extra drain I was measuring. Since I got rid of it, no more drain.

According to Tesla, one of the largest phantom drain is using third party apps that tend to keep the computer on longer, and people checking those apps more than the standard app.

I stopped using the Stats app because it was keeping the car awake (the 12V battery monitor made the problem very obvious). The developer claimed it wasn't Stats, but no one else had my password. No idea whether it was particular to my car or an incompatibility or a temporary issue, or what. I recommend changing your password and only letting the Tesla app have it for a bit, to see if it fixes your problem. It's not enough to log out of Stats. Have to change the password.

You should expect about 1-2 rated miles per day if the car is sleeping well (asleep for about 22 hours a day).

Thank you for this. I currently have TeslaFi and will not be signing up for the paid service. The phantom battery drain is quite significant.
