High Battery Vampire Drain

[KOL2000]

After installing the 8.8 software the vampire drain is dramatically reduced for me.

Im still getting about 2 percent every 8-10 hours. Arrived with 93 percent at 7 am yesterday, didn’t touch my car, everything off, even deleted the Tessie app and disconnected it to be sure. It’s now 9 am today and I’m at 89 percent.

Definitely major issues with sentry mode. Here’s my graph for a few days.

you can tell when I turned it off.

I've notice that the battery charge on my CT is dropping a lot faster than I experience on my Model Y. Last night I charged to 50% finishing at midnight before going to bed. At 6 AM this morning the SOC was down to 48%, a loss of 1/3 % per hour or approx 0.4 kWh/hour. Sentry Mode is off, as is climate control. It's repeatable. Has anyone experienced high phantom drain on their CT? Just thought I'd ask before I put in a Tesla service request.

My battery lost 5% in 12 hrs last night. It started at 75% at 8:30pm and at 8:30am it was 70%. My model 3s do not drain that much (hardly anything). I’ll test tonight by turning sentry mode off.

This seems to be normal for CT at the moment. Did you unplug? People were specifically reporting drain if they were plugged in, after it had finished charging.

powershare?

I've had my AWD for 2 weeks, and just got my240v installed.
I'm in Vegas, and it is over 100 here most of the day right now.
I have to park in the driveway in the sun, and I keep Cabin Overheat set to 90 and have Sentry mode on.
Overnight I lost just under 1/2% per hour.
Monitoring to see if it goes up during the day.

Parking outside and using Sentry and cabin protection I knew I'd have some loss, but keeping the thing cool and protected is worth it. But still seems high.

I've known about similar issues with other models, and know it got fixed eventually.

But it is not cheap, loss is estimated at 15kWh a day. $2.25 in electrical rates.
