I left for 14 days and the truck was in an airport parking garage and it lost 2%.
I lost 7% in 18 days, parked outside. That includes 2% lost to a software update process.

Something is keeping your vehicle on, and that isn't normal. It should not drain as much as it did.
It looks like it is charging 24 hours a day (exact same kWh multiple days in a row) which could be the case if the mobile connector dropped to a low current limit.

It's set to 6 amps. That's why it's the same.

6A @ 120V will take a long time (if ever) with terrible efficiency .
For kicks, I just charged my truck at 6A@240V, in 75F temps for 5 hours.
Gained 3.93kWh. (Around 3%)
Wall energy was 7.39kWh.
Loss was 3.46kWh, or around 693W. Efficiency of 54%.
6A@120 = 720 from wall
-693 = 27W net charge rate.

Here's my truck's charging behavior at 48A@240V.
Only drove 3 days.

curious, how many people actually use cabin overheat protection?

This is ridiculous, we've been out of state for two months now. I noticed the charge dropped substantially and didn't want to come back to a dead battery so I had one of my adult children plugged it in. No climate control and no sentry mode. What the heck is going on? $22.00 of electricity just sitting?

Is it parked, by any chance, in a hot garage? It definitely has to work harder protecting the battery if it is soaking in heat.

Why does my model 3 never lose any power for weeks?
Cybertruck about 2-3 miles a day in the summer nothing on
depends on your climate and how much the battery needs to maintain the temp delta.

I must say my ModelY was much better than my CyberTruck in this regard.

but even at its worst in my garage in some summer days maybe I see 2% SOC drop/day in my CyberTruck… but nothing ridiculous imo

I was loosing 10% in 24hrs. The coolant pump was running 24/7. It is very quite pump you can hear running best near the front right tire. The phone app never showed "Asleep for ...." It took 2 appointments of about a week each to get the problem fixed. Last visit, the service center replaced FUSED - CAR COMPUTER(1780685-S0-G). Now the coolant pump shuts off and the phone app shows it is asleep. I was also having a problem where most of my speakers would stop working after sitting parked for a few hours. An MV reset would get them all working again temporarily. But as an added bonus, replacing the computer has so far resolved that audio speaker problem as well.

I used it consistently on my Model 3 and Cybertruck. This is partly because I have access to cheap energy (my solar), and I prefer keeping my cabin cool to minimize wear and tear on the interior.
