I have been monitoring my 12 V battery for the past week. I noticed the following:
About every one day 1/2 (about 36 hours)
- the battery get charged for about one hour at 14.60 V
- then the battery discharge slowly from 13.20 V to 12.70 V (or about 0.5 V).
I noticed several pics of about 50 mV lasting 10 to 20 mS, and I suppose those correspond to an electrical pump starting.
I lost about 3% a week on the propulsion battery. (3% of 75 kWh ) divided by (7 days of 24 hours) = 2,250 / 168 = 13 Wh.

I have Android, Stats is not available but TezLab is very similar, and you can select the time of use to keep the car sleeping.
I lost 4% over 8 hours last night. Granted it was quite cold but I had sentry off, and I don't have summon. I knew I would have to charge on the way home from work and the battery then went from 10% to 0%. Thankfully I could limp it into the supercharger. I'm wondering if I actually lost more than the 4% and why that happened...
Stats puts my phantom drain at 0.7mph, which is quite high. That's probably because I use Sentry Mode when I'm not at home and when I am at home, I am almost always connected to the wall. Anyway, according to the Stats app, that puts me in the 95-96% percentile of phantom drain for the 3. Woohoo!
